-
-;;; Commentary:
-
-;; This is a direct translation into Emacs LISP of the reference C
-;; implementation of the SHA1 message digest algorithm.
-
-;;; Usage:
-
-;; To compute the SHA1 message digest for a message M (represented as
-;; a string), call
-;; 
-;;   (sha1-encode M)
-;;
-;; which returns the message digest as a hexadecimal string of 20 bytes.
-;; If you need to supply the message in pieces M1, M2, ... Mn, then call
-;; 
-;;   (sha1-init)
-;;   (sha1-update M1)
-;;   (sha1-update M2)
-;;   ...
-;;   (sha1-update Mn)
-;;   (sha1-final)
-
-;;; Notes:
-
-;; The C algorithm uses 32-bit integers; because GNU Emacs
-;; implementations provide 28-bit integers (with 24-bit integers on
-;; versions prior to 19.29), the code represents a 32-bit integer as the
-;; cons of two 16-bit integers.  The most significant word is stored in
-;; the car and the least significant in the cdr.  The algorithm requires
-;; at least 19 bits of integer representation in order to represent the
-;; carry from a 16-bit addition. (see sha1-add())

-
-;;; Commentary:
-
-;; This library perform S/MIME operations from within Emacs.
-;;
-;; Functions for fetching certificates from public repositories are
-;; NOT provided (yet).
-;;
-;; It uses OpenSSL (tested with version 0.9.5a) for signing,
-;; encryption and decryption.
-;;
-;; Some general knowledge of S/MIME, X.509, PKCS#12, PEM etc is
-;; probably required to use this library in any useful way.
-;; Especially, don't expect this library to buy security for you.  If
-;; you don't understand what you are doing, you're as likely to lose
-;; security than gain any by using this library.
-
-;;; Quick introduction:
-
-;; Get your S/MIME certificate from VeriSign or someplace.  I used
-;; Netscape to generate the key and certificate request and stuff, and
-;; Netscape can export the key into PKCS#12 format.
-;;
-;; Enter OpenSSL.  To be able to use this library, it need to have the
-;; SMIME key readable in PEM format.  OpenSSL is used to convert the
-;; key:
-;;
-;; $ openssl pkcs12 -in mykey.p12 -clcerts -nodes > mykey.pem
-;; ...
-;;
-;; Now, use M-x customize-variable smime-keys and add mykey.pem as
-;; a key.
-;;
-;; Now you should be able to sign messages!  Create a buffer and write
-;; something and run M-x smime-sign-buffer RET RET and you should see
-;; your message MIME armoured and a signature.  Encryption, M-x
-;; smime-encrypt-buffer, should also work.
-;;
-;; To be able to verify messages you need to build up trust with
-;; someone.  Perhaps you trust the CA that issued your certificate, at
-;; least I did, so I export it's certificates from my PKCS#12
-;; certificate with:
-;;
-;; $ openssl pkcs12 -in mykey.p12 -cacerts -nodes > cacert.pem
-;; ...
-;;
-;; Now, use M-x customize-variable smime-CAs and add cacert.pem as a
-;; CA certificate.
-;;
-;; You should now be able to sign messages, and even verify messages
-;; sent by others that use the same CA as you.
-
-;; Bugs:
-;;
-;; Don't complain that this package doesn't do encrypted PEM files,
-;; submit a patch instead.  I store my keys in a safe place, so I
-;; didn't need the encryption.  Also, programming this was made a lot
-;; easier by that decision.  One might think that this even influenced
-;; were I store my keys, and one would probably be right. :-)
-;;
-;; Suggestions and comments are appreciated, mail me at simon@josefsson.org.
-
-;; <rant>
-;;
-;; I would include pointers to introductory text on concepts used in
-;; this library here, but the material I've read are so horrible I
-;; don't want to recomend them.
-;;
-;; Why can't someone write a simple introduction to all this stuff?
-;; Until then, much of this resemble security by obscurity.
-;;
-;; Also, I'm not going to mention anything about the wonders of
-;; cryptopolitics.  Oops, I just did.

-;;; Commentary:
-
-;; This implement decoding of RFC2646 formatted text, including the
-;; quoted-depth wins rules.
-
-;; Theory of operation: search for lines ending with SPC, save quote
-;; length of line, remove SPC and concatenate line with the following
-;; line if quote length of following line matches current line.
-
-;; When no further concatenations are possible, we've found a
-;; paragraph and we let `fill-region' fill the long line into several
-;; lines with the quote prefix as `fill-prefix'.
-
-;; Todo: encoding
-
-;; History:
-
-;; 2000-02-17  posted on ding mailing list
-;; 2000-02-19  use `point-at-{b,e}ol' in XEmacs
-;; 2000-03-11  no compile warnings for point-at-bol stuff

-;;; Commentary:
-
-;; This package provides an abstraction to RFC822-style messages, used in
-;; mail news, and some other systems.  The simple syntactic rules for such
-;; headers, such as quoting and line folding, are routinely reimplemented
-;; in many individual packages.  This package removes the need for this
-;; redundancy by representing message headers as association lists,
-;; offering functions to extract the set of headers from a message, to
-;; parse individual headers, to merge sets of headers, and to format a set
-;; of headers.
-
-;; The car of each element in the message-header alist is a symbol whose
-;; print name is the name of the header, in all lower-case.  The cdr of an
-;; element depends on the operation.  After extracting headers from a
-;; message, it is a string, the value of the header.  An extracted set of
-;; headers may be parsed further, which may turn it into a list, whose car
-;; is the original value and whose subsequent elements depend on the
-;; header.  For formatting, it is evaluated to obtain the strings to be
-;; inserted.  For merging, one set of headers consists of strings, while
-;; the other set will be evaluated with the symbols in the first set of
-;; headers bound to their respective values.

-;;; md5.el -- MD5 Message Digest Algorithm
-;;; Gareth Rees <gdr11@cl.cam.ac.uk>
-
-;; LCD Archive Entry:
-;; md5|Gareth Rees|gdr11@cl.cam.ac.uk|
-;; MD5 cryptographic message digest algorithm|
-;; 13-Nov-95|1.0|~/misc/md5.el.Z|
-
-;;; Details: ------------------------------------------------------------------
-
-;; This is a direct translation into Emacs LISP of the reference C
-;; implementation of the MD5 Message-Digest Algorithm written by RSA
-;; Data Security, Inc.
-;;
-;; The algorithm takes a message (that is, a string of bytes) and
-;; computes a 16-byte checksum or "digest" for the message.  This digest
-;; is supposed to be cryptographically strong in the sense that if you
-;; are given a 16-byte digest D, then there is no easier way to
-;; construct a message whose digest is D than to exhaustively search the
-;; space of messages.  However, the robustness of the algorithm has not
-;; been proven, and a similar algorithm (MD4) was shown to be unsound,
-;; so treat with caution!
-;;
-;; The C algorithm uses 32-bit integers; because GNU Emacs
-;; implementations provide 28-bit integers (with 24-bit integers on
-;; versions prior to 19.29), the code represents a 32-bit integer as the
-;; cons of two 16-bit integers.  The most significant word is stored in
-;; the car and the least significant in the cdr.  The algorithm requires
-;; at least 17 bits of integer representation in order to represent the
-;; carry from a 16-bit addition.
-
-;;; Usage: --------------------------------------------------------------------
-
-;; To compute the MD5 Message Digest for a message M (represented as a
-;; string or as a vector of bytes), call
-;;
-;;   (md5-encode M)
-;;
-;; which returns the message digest as a vector of 16 bytes.  If you
-;; need to supply the message in pieces M1, M2, ... Mn, then call
-;;
-;;   (md5-init)
-;;   (md5-update M1)
-;;   (md5-update M2)
-;;   ...
-;;   (md5-update Mn)
-;;   (md5-final)

-;;; Commentary:
-
-;; This file contains some small additions to message mode:
-;;    * inserting files in a message and explicit marking it
-;;      as something somebody else has created,
-;;    * change Subject: header and add (was: <old subject>)
-;;    * strip (was: <old subject>) from Subject: headers
-;;    * add a X-No-Archieve: Yes header and a note in the body
-;;    * a function for cross-post and followup-to messages
-;;    * replace To: header with contents of Cc: or Bcc: header.
-;;

-;;; Generalized mailcap parsing and access routines
-;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
-;;;
-;;; Data structures
-;;; ---------------
-;;; The mailcap structure is an assoc list of assoc lists.
-;;; 1st assoc list is keyed on the major content-type
-;;; 2nd assoc list is keyed on the minor content-type (which can be a regexp)
-;;;
-;;; Which looks like:
-;;; -----------------
-;;; (
-;;;  ("application"
-;;;   ("postscript" . <info>)
-;;;  )
-;;;  ("text"
-;;;   ("plain" . <info>)
-;;;  )
-;;; )
-;;;
-;;; Where <info> is another assoc list of the various information
-;;; related to the mailcap RFC.  This is keyed on the lowercase
-;;; attribute name (viewer, test, etc).  This looks like:
-;;; (("viewer" . viewerinfo)
-;;;  ("test"   . testinfo)
-;;;  ("xxxx"   . "string")
-;;; )
-;;;
-;;; Where viewerinfo specifies how the content-type is viewed.  Can be
-;;; a string, in which case it is run through a shell, with
-;;; appropriate parameters, or a symbol, in which case the symbol is
-;;; funcall'd, with the buffer as an argument.
-;;;
-;;; testinfo is a list of strings, or nil.  If nil, it means the
-;;; viewer specified is always valid.  If it is a list of strings,
-;;; these are used to determine whether a viewer passes the 'test' or
-;;; not.
-;;;
-;;; The main interface to this code is:
-;;;
-;;; To set everything up:
-;;;
-;;;  (mm-parse-mailcaps [path])
-;;;
-;;;  Where PATH is a unix-style path specification (: separated list
-;;;  of strings).  If PATH is nil, the environment variable MAILCAPS
-;;;  will be consulted.  If there is no environment variable, then a
-;;;  default list of paths is used.
-;;;
-;;; To retrieve the information:
-;;;  (mm-mime-info st [nd] [request])
-;;;
-;;;  Where st and nd are positions in a buffer that contain the
-;;;  content-type header information of a mail/news/whatever message.
-;;;  st can optionally be a string that contains the content-type
-;;;  information.
-;;;
-;;;  Third argument REQUEST specifies what information to return.  If
-;;;  it is nil or the empty string, the viewer (second field of the
-;;;  mailcap entry) will be returned.  If it is a string, then the
-;;;  mailcap field corresponding to that string will be returned
-;;;  (print, description, whatever).  If a number, then all the
-;;;  information for this specific viewer is returned.
-;;;

-This package contains a beta version of Gnus.  The lisp directory
-contains the source lisp files, and the texi directory contains a
-draft of the Gnus info pages.
-
-To use Gnus you first have to unpack the files, which you've obviously
-done, because you are reading this.
-
-You should definitely byte-compile the source files. To do that, you
-can simply say "./configure; make" in this directory.  If you are
-using XEmacs, you *must* say "make EMACS=xemacs".  In that case you
-may also want to pull down the package of nice glyphs from
-<URL:http://www.gnus.org/etc.tar.gz>.  It should be installed
-into the "gnus-5.4.53/etc" directory.
-
-Then you have to tell Emacs where Gnus is. You might put something
-like
-
-   (setq load-path (cons (expand-file-name "~/gnus-5.4.53/lisp") load-path))
-
-in your .emacs file, or wherever you keep such things.  
-
-To enable reading the Gnus manual, you could say something like:
-
-  (setq Info-default-directory-list 
-        (cons "~/gnus-5.4.53/texi" Info-default-directory-list))
-
-Note that Gnus and GNUS can't coexist in a single Emacs. They both use
-the same function and variable names.  If you have been running GNUS
-in your Emacs, you should probably exit that Emacs and start a new one
-to fire up Gnus.
-
-Gnus does absolutely not work with anything older than Emacs 19.33 or
-XEmacs 19.14.  So you definitely need a new Emacs.
-
-Then you do a `M-x gnus', and everything should... uhm... it should
-work, but it might not. Set `debug-on-error' to t, and mail me the
-backtraces, or, better yet, find out why Gnus does something wrong,
-fix it, and send me the diffs. :-)
-
-There are four main things I want your help and input on:
-
-1) Startup. Does everything go smoothly, and why not?
-
-2) Any errors while you read news normally?
-
-3) Any errors if you do anything abnormal?
-
-4) Features you do not like, or do like, but would like to tweak a
-   bit, and features you would like to see.
-
-Send any comments and all your bug fixes/complaints to
-`bugs@gnus.org'.

-@section Introduction
-
-This library allows customization of @dfn{user options}.  Currently two
-types of user options are supported, namely @dfn{variables} and
-@dfn{faces}.  Each user option can have four different values
-simultaneously:
-@table @dfn
-@item factory setting
-The value specified by the programmer.
-@item saved value
-The value saved by the user as the default for this variable.  This
-overwrites the factory setting when starting a new emacs.
-@item current value
-The value used by Emacs.  This will not be remembered next time you
-run Emacs.
-@item widget value
-The value entered by the user in a customization buffer, but not yet
-applied.
-@end table
-
-Variables also have a @dfn{type}, which specifies what kind of values
-the variable can hold, and how the value is presented in a customization
-buffer.  By default a variable can hold any valid expression, but the
-programmer can specify a more limited type when declaring the variable.
-
-The user options are organized in a number of @dfn{groups}.  Each group
-can contain a number user options, as well as other groups.  The groups
-allows the user to concentrate on a specific part of emacs.
-
-@node  User Commands, The Customization Buffer, Introduction, Top
-@comment  node-name,  next,  previous,  up
-@section User Commands
-
-The following commands will create a customization buffer:
-
-@table @code
-@item customize
-Create a customization buffer containing a specific group, by default
-the @code{emacs} group.
-
-@item customize-variable
-Create a customization buffer containing a single variable.  
-
-@item customize-face
-Create a customization buffer containing a single face.
-
-@item customize-apropos
-Create a customization buffer containing all variables, faces, and
-groups that match a user specified regular expression.
-@end table
-
-@node The Customization Buffer, Declarations, User Commands, Top
-@comment  node-name,  next,  previous,  up
-@section The Customization Buffer.
-
-The customization buffer allows the user to make temporary or permanent
-changes to how specific aspects of emacs works, by setting and editing
-user options.  
-
-The customization buffer contains three types of text:
-
-@table @dfn
-@item informative text
-where the normal editing commands are disabled.
-
-@item editable fields
-where you can edit with the usual emacs commands.  Editable fields are
-usually displayed with a grey background if your terminal supports
-colors, or an italic font otherwise.
-
-@item buttons
-which can be activated by either pressing the @kbd{@key{ret}} while
-point is located on the text, or pushing @kbd{mouse-2} while the mouse
-pointer is above the tex.  Buttons are usually displayed in a bold
-font. 
-@end table
-
-You can move to the next the next editable field or button by pressing
-@kbd{@key{tab}} or the previous with @kbd{M-@key{tab}}.  Some buttons
-have a small helpful message about their purpose, which will be
-displayed when you move to it with the @key{tab} key.  
-
-The buffer is divided into three part, an introductory text, a list of
-customization options, and a line of customization buttons.  Each part
-will be described in the following. 
-
-@menu
-* The Introductory Text::       
-* The Customization Options::   
-* The Variable Options::        
-* The Face Options::            
-* The Group Options::           
-* The State Button::            
-* The Customization Buttons::   
-@end menu
-
-@node  The Introductory Text, The Customization Options, The Customization Buffer, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection  The Introductory Text
-
-The start of the buffer contains a short explanation of what it is, and
-how to get help.  It will typically look like this:
-
-@example
-This is a customization buffer.
-Push RET or click mouse-2 on the word _help_ for more information.
-@end example
-
-Rather boring.  It is mostly just informative text, but the word
-@samp{help} is a button that will bring up this document when
-activated.  
-
-@node  The Customization Options, The Variable Options, The Introductory Text, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection The Customization Options
-
-Each customization option looks similar to the following text:
-
-@example
- *** custom-background-mode: default 
- State: this item is unchanged from its factory setting.
- [ ] [?] The brightness of the background.
-@end example
-
-The option contains the parts described below.
-
-@table @samp
-@item ***
-The Level Button.  The customization options in the buffer are organized
-in a hierarchy, which is indicated by the number of stars in the level
-button.  The top level options will be shown as @samp{*}.  When they are
-expanded, the suboptions will be shown as @samp{**}.  The example option
-is thus a subsuboption.
-
-Activating the level buttons will toggle between hiding and exposing the
-content of that option.  The content can either be the value of the
-option, as in this example, or a list of suboptions.
-
-@item custom-background-mode
-This is the tag of the the option.  The tag is a name of a variable, a
-face, or customization group.  Activating the tag has an effect that
-depends on the exact type of the option.  In this particular case,
-activating the tag will bring up a menu that will allow you to choose
-from the three possible values of the `custom-background-mode'
-variable. 
-
-@item default
-After the tag, the options value is shown.  Depending on its type, you
-may be able to edit the value directly.  If an option should contain a
-file name, it is displayed in an editable field, i.e. you can edit it
-using the standard emacs editing commands.
-
-@item State: this item is unchanged from its factory setting.
-The state line.  This line will explain the state of the option,
-e.g. whether it is currently hidden, or whether it has been modified or
-not.  Activating the button will allow you to change the state, e.g. set
-or reset the changes you have made.  This is explained in detail in the
-following sections.
-
-@item [ ]
-The magic button.  This is an abbreviated version of the state line. 
-
-@item [?] 
-The documentation button.  If the documentation is more than one line,
-this button will be present.  Activating the button will toggle whether
-the complete documentation is shown, or only the first line.
-
-@item The brightness of the background.
-This is a documentation string explaining the purpose of this particular
-customization option.
-
-@end table

-@node  The Variable Options, The Face Options, The Customization Options, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection The Variable Options
-
-The most common customization options are emacs lisp variables.  The
-actual editing of these variables depend on what type values the
-variable is expected to contain.  For example, a lisp variable whose
-value should be a string will typically be represented with an editable
-text field in the buffer, where you can change the string directly.  If
-the value is a list, each item in the list will be presented in the
-buffer buffer on a separate line, with buttons to insert new items in
-the list, or delete existing items from the list.  You may want to see 
-@ref{User Interface,,, widget, The Widget Library}, where some examples
-of editing are discussed.  
-
-You can either choose to edit the value directly, or edit the lisp
-value for that variable.  The lisp value is a lisp expression that
-will be evaluated when you start emacs.  The result of the evaluation
-will be used as the initial value for that variable.  Editing the
-lisp value is for experts only, but if the current value of the
-variable is of a wrong type (i.e. a symbol where a string is expected),
-the `edit lisp' mode will always be selected.
-
-You can see what mode is currently selected by looking at the state
-button.  If it uses parenthesises (like @samp{( )}) it is in edit lisp
-mode, with square brackets (like @samp{[ ]}) it is normal edit mode.
-You can switch mode by activating the state button, and select either
-@samp{Edit} or @samp{Edit lisp} from the menu.
-
-You can change the state of the variable with the other menu items:
-
-@table @samp
-@item Set
-When you have made your modifications in the buffer, you need to
-activate this item to make the modifications take effect.  The
-modifications will be forgotten next time you run emacs.
-
-@item Save
-Unless you activate this item instead!  This will mark the modification
-as permanent, i.e. the changes will be remembered in the next emacs
-session.
-
-@item Reset
-If you have made some modifications and not yet applied them, you can
-undo the modification by activating this item.
-
-@item Reset to Saved
-Activating this item will reset the value of the variable to the last
-value you marked as permanent with `Save'.
-
-@item Reset to Factory Settings
-Activating this item will undo all modifications you have made, and
-reset the value to the initial value specified by the program itself. 
-@end table
-
-By default, the value of large or complicated variables are hidden.   You
-can show the value by clicking on the level button.
-
-@node  The Face Options, The Group Options, The Variable Options, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection The Face Options
-
-A face is an object that controls the appearance of some buffer text.
-The face has a number of possible attributes, such as boldness,
-foreground color, and more.  For each attribute you can specify whether
-this attribute is controlled by the face, and if so, what the value is.
-For example, if the attribute bold is not controlled by a face, using
-that face on some buffer text will not affect its boldness.  If the bold
-attribute is controlled by the face, it can be turned either on or of.
-
-It is possible to specify that a face should have different attributes
-on different device types.  For example, a face may make text red on a
-color device, and bold on a monochrome device.  You do this by
-activating `Edit All' in the state menu.
-
-The way this is presented in the customization buffer is to have a list
-of display specifications, and for each display specification a list of
-face attributes.  For each face attribute, there is a checkbox
-specifying whether this attribute has effect and what the value is.
-Here is an example:
-
-@example
- *** custom-invalid-face: (sample)
- State: this item is unchanged from its factory setting.
- [ ] Face used when the customize item is invalid.
- [INS] [DEL] Display: [ ] Type: [ ] X [ ] PM [ ] Win32 [ ] DOS [ ] TTY
-                      [X] Class: [X] Color [ ] Grayscale [ ] Monochrome
-                      [ ] Background: [ ] Light [ ] Dark
-             Attributes: [ ] Bold: off 
-                         [ ] Italic: off 
-                         [ ] Underline: off 
-                         [X] Foreground: yellow (sample)
-                         [X] Background: red (sample)
-                         [ ] Stipple:  
- [INS] [DEL] Display: all
-             Attributes: [X] Bold: on 
-                         [X] Italic: on 
-                         [X] Underline: on 
-                         [ ] Foreground: default (sample)
-                         [ ] Background: default (sample)
-                         [ ] Stipple:  
- [INS]
-@end example
-
-This has two display specifications.  The first will match all color
-displays, independently on what window system the device belongs to, and
-whether background color is dark or light.  For devices matching this
-specification, @samp{custom-invalid-face} will force text to be
-displayed in yellow on red, but leave all other attributes alone.
-
-The second display will simply match everything.  Since the list is
-prioritised, this means that it will match all non-color displays.  For
-these, the face will not affect the foreground or background color, but
-force the font to be both bold, italic, and underline.
-
-You can add or delete display specifications by activating the
-@samp{[INS]} and @samp{[DEL]} buttons, and modify them by clicking on
-the check boxes.  The first checkbox in each line in the display
-specification is special.  It specify whether this particular property
-will even be relevant.  By not checking the box in the first display, we
-match all device types, also device types other than those listed.
-
-After modifying the face, you can activate the state button to make the
-changes take effect.  The menu items in the state button menu is similar
-to the state menu items for variables described in the previous section.

-@node  The Group Options, The State Button, The Face Options, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection The Group Options
-
-Since Emacs has approximately a zillion configuration options, they have
-been organized in groups.  Each group can contain other groups, thus
-creating a customization hierarchy.  The nesting of the customization
-within the visible part of this hierarchy is indicated by the number of
-stars in the level button.
-
-Since there is really no customization needed for the group itself, the
-menu items in the groups state button will affect all modified group
-members recursively.  Thus, if you activate the @samp{Set} menu item,
-all variables and faces that have been modified and belong to that group
-will be applied.  For those members that themselves are groups, it will
-work as if you had activated the @samp{Set} menu item on them as well.
-
-@node  The State Button, The Customization Buttons, The Group Options, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection The State Line and The Magic Button
-
-The state line has two purposes.  The first is to hold the state menu,
-as described in the previous sections.  The second is to indicate the
-state of each customization item.  
-
-For the magic button, this is done by the character inside the brackets.
-The following states have been defined, the first that applies to the
-current item will be used:
-
-@table @samp
-@item -
-The option is currently hidden.  For group options that means the
-members are not shown, for variables and faces that the value is not
-shown.  You cannot perform any of the state change operations on a
-hidden customization option.
-
-@item *
-The value if this option has been modified in the buffer, but not yet
-applied.  
-
-@item +
-The item has has been set by the user.
-
-@item :
-The current value of this option is different from the saved value.   
-
-@item !
-The saved value of this option is different from the factory setting.
-
-@item @@
-The factory setting of this option is not known.  This occurs when you
-try to customize variables or faces that have not been explicitly
-declared as customizable.
-
-@item SPC
-The factory setting is still in effect.
-
-@end table
-
-For non-hidden group options, the state shown is the most severe state
-of its members, where more severe means that it appears earlier in the
-list above (except hidden members, which are ignored).
-
-@node  The Customization Buttons,  , The State Button, The Customization Buffer
-@comment  node-name,  next,  previous,  up
-@subsection The Customization Buttons
-
-The last part of the customization buffer looks like this:
-
-@example
-[Set] [Save] [Reset] [Done]
-@end example
-
-Activating the @samp{[Set]}, @samp{[Save]}, or @samp{[Reset]}
-button will affect all modified customization items that are visible in
-the buffer.  @samp{[Done]} will bury the buffer.

-Groups, variables, and faces all share these common keywords:
-
-@table @code
-@item :group
-@var{value} should be a customization group. 
-Add @var{symbol} to that group. 
-@item :link
-@var{value} should be a widget type.

-Useful widget types include @code{custom-manual}, @code{info-link}, and
-@code{url-link}. 
-@item :load
-Add @var{value} to the files that should be loaded nefore displaying
-this customization option.  The value should be iether a string, which

-@subsection Declaring Faces
-
-Faces are declared with @code{defface}.
-
-@defun defface face spec doc [keyword value]... 
-
-Declare @var{face} as a customizable face that defaults to @var{spec}.
-@var{face} does not need to be quoted.
-
-If @var{face} has been set with `custom-set-face', set the face attributes
-as specified by that function, otherwise set the face attributes
-according to @var{spec}.
-
-@var{doc} is the face documentation.
-
-@var{spec} should be an alist of the form @samp{((@var{display} @var{atts})...)}.
-
-@var{atts} is a list of face attributes and their values.  The possible
-attributes are defined in the variable `custom-face-attributes'.
-Alternatively, @var{atts} can be a face in which case the attributes of
-that face is used.
-
-The @var{atts} of the first entry in @var{spec} where the @var{display}
-matches the frame should take effect in that frame.  @var{display} can
-either be the symbol `t', which will match all frames, or an alist of
-the form @samp{((@var{req} @var{item}...)...)}@refill
-
-For the @var{display} to match a FRAME, the @var{req} property of the
-frame must match one of the @var{item}.  The following @var{req} are
-defined:@refill
-
-@table @code
-@item type
-(the value of (window-system))@*
-Should be one of @code{x} or @code{tty}.
-
-@item class
-(the frame's color support)@*
-Should be one of @code{color}, @code{grayscale}, or @code{mono}.
-
-@item background
-(what color is used for the background text)@*
-Should be one of @code{light} or @code{dark}.
-@end table
-  
-Internally, custom uses the symbol property @code{factory-face} for the
-program specified default face properties, @code{saved-face} for
-properties saved by the user, and @code{face-doc-string} for the
-documentation string.@refill

-@node Usage for Package Authors,  , Declaring Faces, Declarations
-@comment  node-name,  next,  previous,  up
-@subsection Usage for Package Authors
-
-The recommended usage for the author of a typical emacs lisp package is
-to create one group identifying the package, and make all user options
-and faces members of that group.  If the package has more than around 20
-such options, they should be divided into a number of subgroups, with
-each subgroup being member of the top level group.
-
-The top level group for the package should itself be member of one or
-more of the standard customization groups.  There exists a group for
-each @emph{finder} keyword.  Press @kbd{C-c p} to see a list of finder
-keywords, and add you group to each of them, using the @code{:group}
-keyword. 
-
-@node  Utilities, The Init File, Declarations, Top
-@comment  node-name,  next,  previous,  up
-@section Utilities
-
-These utilities can come in handy when adding customization support. 
-
-@deffn Widget custom-manual
-Widget type for specifying the info manual entry for a customization
-option.  It takes one argument, an info address.
-@end deffn
-
-@defun custom-add-to-group group member widget
-To existing @var{group} add a new @var{member} of type @var{widget},
-If there already is an entry for that member, overwrite it.
-@end defun
-
-@defun custom-add-link symbol widget
-To the custom option @var{symbol} add the link @var{widget}.
-@end defun
-
-@defun custom-add-load symbol load
-To the custom option @var{symbol} add the dependency @var{load}.
-@var{load} should be either a library file name, or a feature name.
-@end defun
-
-@defun custom-menu-create symbol &optional name
-Create menu for customization group @var{symbol}.
-If optional @var{name} is given, use that as the name of the menu. 
-Otherwise make up a name from @var{symbol}.
-The menu is in a format applicable to @code{easy-menu-define}.
-@end defun
-
-@node  The Init File, Wishlist, Utilities, Top
-@comment  node-name,  next,  previous,  up
-@section The Init File
-
-When you save the customizations, call to @code{custom-set-variables},
-@code{custom-set-faces} are inserted into the file specified by
-@code{custom-file}.  By default @code{custom-file} is your @file{.emacs}
-file.  If you use another file, you must explicitly load it yourself.
-The two functions will initialize variables and faces as you have
-specified.
-
-@node  Wishlist,  , The Init File, Top
-@comment  node-name,  next,  previous,  up
-@section Wishlist
-
-@itemize @bullet
-@item
-The menu items should be grayed out when the information is
-missing.  I.e. if a variable doesn't have a factory setting, the user
-should not be allowed to select the @samp{Factory} menu item.
-
-@item 
-Better support for keyboard operations in the customize buffer.
-
-@item
-Integrate with @file{w3} so you can customization buffers with much
-better formatting.  I'm thinking about adding a <custom>name</custom>
-tag.  The latest w3 have some support for this, so come up with a
-convincing example.
-
-@item
-Add an `examples' section, with explained examples of custom type
-definitions. 
-
-@item
-Support selectable color themes.  I.e., change many faces by setting one
-variable.
-
-@item
-Support undo using lmi's @file{gnus-undo.el}.
-
-@item
-Make it possible to append to `choice', `radio', and `set' options.
-
-@item
-Make it possible to customize code, for example to enable or disable a
-global minor mode.
-
-@item
-Ask whether set or modified variables should be saved in
-@code{kill-buffer-hook}. 
-
-Ditto for @code{kill-emacs-query-functions}.
-
-@item
-Command to check if there are any customization options that
-does not belong to an existing group. 
-
-@item
-Optionally disable the point-cursor and instead highlight the selected
-item in XEmacs.  This is like the *Completions* buffer in XEmacs.
-Suggested by Jens Lautenbacher
-@samp{<jens@@lemming0.lem.uni-karlsruhe.de>}.@refill
-
-@item
-Empty customization groups should start open (harder than it looks).
-

-@chapter Mail with Gnus
-
-Quite a few people wish to read mail with Gnus but stumble across a few
-issues which make this a bit difficult.  This comes from the fact that
-Gnus is really a newsreader, and thus it treats mail in a newsreaderly
-fashion.  It is not desirable to change this, because it is a wonderful
-thing and this is what distinguishes Gnus from other mail readers.  In
-this little tutorial, I'll try to explain what ``newsreaderly fashion''
-means and how exactly Gnus treats mail.
-
-Specific pieces of behavior can always be changed, but if you desire to
-make Gnus behave like a conventional mail reader, think again.  It will
-be an uphill battle.  Maybe a different mail reader is for you?  But
-also, read on.  Maybe you'll find the right behavior in the description
-below.
-
-@c ------------------------------------------------------------ 
-@section Gnus Terminology
-@c ------------------------------------------------------------ 
-
-First, let's talk about a few terms which I'm going to use which might
-be unfamiliar to you.
-
-@table @dfn
-@item Posting, Article, Message, Mail
-These are all related terms.  A news message might also be called a
-posting or an article, whereas a mail message is known as a mail.  Since
-Gnus treats both news and mail, the distinction isn't as clear.  In the
-following, I'll use the term ``message'' for the generic case and ``news
-message'' and ``mail message'' for the specific cases.  But sometimes, I
-might use ``posting'' or ``article'', too, both synonymous with
-``message''.
-
-@item Backend
-Gnus can read messages from various sources.  On the one hand, there is
-news, and on the other hand, there is mail.  News can be read from a
-news server (an NNTP server), or from a so-called spool directory.  Mail
-can be read in various formats.
-
-Generally speaking, a backend describes the way Gnus accesses a set of
-messages.  For a news server, this is the Network News Transfer
-Protocol, NNTP, and thus there is a backend ``nntp''.  For mail stored
-in the same format that the MH message handling system used, there is
-the backend ``nnmh''.  And so on.  See below for a list of backends.
-
-@item Server
-Whereas a backend describes the mechanism used by Gnus to access the
-messages, a server is a specific instance of that mechanism.  You might
-create a specific server for accessing the host @file{news.frob.org}
-using NNTP, say.  Or you might create a server for accessing the
-MH-style directory @file{~/OldMail}.
-
-If you are a programmer, think of a backend as the class and of a server
-as an object (instance) of that class.  If you are a cook, think of a
-backend as an apple pie recipe (say), and think of a server as an actual
-apple pie.  (Yummy!)  If you live in a huge city, think of a backend as
-a bus (or tram, or underground) line (the Circle Line comes to mind),
-and think of a server as a specific bus (or tram train, or underground
-train).  The one at 8:15 last Monday morning, for example.  If you drive
-a car, think of a backend as the model and make and of a server as a
-specific car.
-
-Obviously, there can be two servers using the same backend.  (Two
-instances of the same class, two apple pies baked according to the same
-recipe, two busses going the same route, two cars of the same model.)
-
-@item (Select) method
-Just another term for server.
-
-@item Native server
-This is the primary server, so to speak.  Most people let their news
-server be the native server, hence:
-@lisp
-(setq gnus-select-method '(nntp "news.frob.org"))
-@end lisp
-Groups from the native server are also known as native groups.
-
-@item Secondary select methods
-This is a list of other servers which one also wishes to use.  Many
-people are only going to have two servers, one native (for news) and one
-secondary (for mail).  Thus:
-@lisp
-(setq gnus-secondary-select-methods '((nnml "")))
-@end lisp
-Note that there is one more pair of parentheses in order to be able to
-mention more than one seconary select method.
-
-Groups from a secondary server are also known as secondary groups.
-
-In order to be able to distinguish native groups from secondary groups,
-each server is identified with a (unique) name and that name is used as
-a prefix for the secondary groups.  Thus, you might have a group
-@file{gnu.emacs.help} (which is native) and another group
-@file{nnml:mail.misc} (which is secondary).  A plus character is used if
-the name of a server is not the empty string.  For example, given the
-following in your @file{.gnus} file
-@lisp
-(setq gnus-secondary-select-methods
-      '((nnml "work" (nnml-directory "~/Mail.work/"))
-        (nnml "play" (nnml-directory "~/Mail.play/"))))
-@end lisp
-you might have the groups @file{nnml+work:boss} and
-@file{nnml+play:so}@footnote{``SO'' standing for ``significant other'',
-i.e.@ girlfriend or boyfriend}.
-
-@item Group
-Well, if you've read news before, you know about different news groups.
-One of my favorites is @file{gnu.emacs.gnus}, and I wish I would read
-@file{alt.fan.pratchett}.  Since Gnus treats mail in a newsreaderly
-fashion, it is obvious that it uses groups rather than ``folders'' like
-other mail readers do.  So with Gnus there are news groups and mail
-groups, where mail groups are known as mail folders to other programs.
-
-Each group belongs to a certain server, and each server uses a certain
-backend.
-
-@item Expiry
-News servers offer news groups which contain news postings.  New news
-postings come in, so the news postings accumulate, and pretty soon the
-new hard disk is full.  This is not good news at all.
-
-Thus, a news server does what is known as @dfn{expiry}: it deletes old
-messages.  Of course, on a news server, expiry happens with no regard of
-whether people have already seen the message in question; instead, the
-news server admin chooses expiry times based on available disk space and
-maybe on the normal amount of traffic in a news group.
-
-But mail messages should be under the users' control, so there better be
-no server which deletes messages regardless of users having seen them!
-Instead, Gnus adopts a scheme where users say which messages may be
-deleted, and Gnus takes care of deleting them after a while.  (They are
-not deleted immediately in case you made a mistake, or in case you wish
-to refer back to an old article.)
-
-@item Article marks
-Gnus distinguishes between a number of article marks, which indicate
-whether they have been looked at, or are considered important, or the
-like.  Marks are represented by a character.
-
-If that character is a space, it looks as if the message isn't marked at
-all.  These messages are called @dfn{unmarked}, the mark character used
-is a space, and marking a message with space is considered to be the
-same as removing all marks---after all, such messages are unmarked.  You
-can type @kbd{M-u} to remove all marks and make an article unmarked.
-
-Articles that are considered important or where you wish to indicate
-that you have to deal with them later can be @dfn{ticked}.  The mark
-character used for ticked messages is the exclamation mark, and you can
-use @kbd{u} or @kbd{!} to tick messages.  Ticked messages are always
-shown when you enter a group.
-
-There is the @dfn{dormant} mark which is similar to the ticked mark but
-does not imply importance or urgency; thus, dormant messages aren't
-shown by default.  The mark character used is the question mark, and you
-can mark messages as dormant using the @kbd{?} key.
-
-So far, each kind of mark was associated with one character (as was the
-absence of any mark).  But articles which you have read are a bit
-different, since lots of different characters are used here.  The
-important thing to realize is that these messages are treated in the
-same way by Gnus; the different characters are only used as an
-information for the user.
-
-Articles which are marked as read because you have actually read them
-(the normal case, one would think) are marked with the `R' character.
-(Type @kbd{@key{SPC}} or @kbd{g} to read a message, or click on it using
-the middle mouse button, @kbd{@key{mouse-2}}.)  You can also mark a
-message as read without actually reading it, this is indicated with the
-`r' character and can be achieved with @kbd{d} or @kbd{M r}.
-
-After exiting a group and then entering it again (some time later), the
-messages that had been marked as read before appear with the `O'
-character.
-
-To reiterate: the difference between `r', `R' and `O' is only an
-information for the user.

-@section Choosing a mail backend
-@c ------------------------------------------------------------
-
-The Gnus manual lists quite a few backends.  Of these, the news backends
-pose no problem: you use the @code{nntp} backend if you access a news
-server and the @code{nnspool} backend if you have a local news spool
-directory.  (Leafnode users should use @code{nntp} so that the leafnode
-program can see what you are doing and choose the groups to download
-accordingly.)  But the mail backends are more difficult.  There are many
-of them, and it is not obvious which is the best choice.  In quite a few
-cases, this is because there is no single best choice; or maybe what's
-the best choice depends on the group or changes over time.
-
-Below, I'll give a list of mail backends.  While I say something about
-how messages are stored, I'll try to emphasize what that means for you
-as a user.
-
-Let's try to structure the discussion a bit.  We have servers, which
-contain groups, which in turn contain messages.  How could we store this
-on disk?  After some thought, you'll quickly come up with the following
-alternatives:  You could store all messages from a server in one file.
-The second alternative is to store all messages from one group in one
-file, different groups are stored in different files.  A third
-alternative is to store each message in one file; in this case, one
-could use a directory per group.  A very interesting fourth alternative
-is not to store the messages at all but instead to use the Oracle of
-Delphi (say) to predict what the messages will be; this saves a lot of
-disk space.  I won't talk about the fourth alternative in the following.
-
-
-@subsection Backends with one file per server
-
-Many people use just two servers, the native server for news and a
-secondary server for mail.  Thus, this alternative would mean that you
-store all your mail in one file.  Since Emacs has no fancy mechanisms to
-access parts of files, this means that Gnus loads that file into main
-memory at startup, and all your mails are kept in main memory all the
-time.  (Of course, copies are written to disk every now and then, for
-safekeeping!)
-
-I think you can pretty much figure out the consequences on your own,
-now:
-@itemize @bullet
-@item
-Handling large amounts of mail will be a problem.  (Emacs has a maximum
-file size of 128 MB.)
-
-@item
-Some operations on mails will be fast, since they are in-memory
-operations.  (Saving everything to disk will be slow, though.)
-
-@item
-Some operations on mails will be slow, since they have to search through
-the whole file.
-
-@item
-It is convenient to have all mail stored in one file: you can easily
-transfer it to another computer using FTP, say, or store it on a floppy
-or Zip disk or a tape.
-
-@end itemize
-
-Conclusion: If you don't have a lot of mail to deal with and like the
-convenience of storing it all in one file, one of these backends might
-be for you.  However, since Gnus really shines when dealing with lots of
-mails, most Gnus users can be expected to deal with quite a large volume
-of mail.  Thus, I don't think many Gnus users choose one of these
-backends.
-
-@table @code
-@item nnmbox
-This backend uses the well-known ``mbox'' format for storing mails.  In
-this format, a message begins with the five characters @code{From_} (the
-last character is a space) at the beginning of a line, and ends with an
-empty line.
-
-@item nnbabyl
-This backend uses the lesser known ``babyl'' format for storing mails.
-This uses delimiters for the beginning and the end of a message which
-are less likely to occur in a message.
-
-@quotation
-CCC Are they guaranteed to never occur?
-@end quotation
-
-One advantage of a babyl file over an mbox file is that it is possible
-to insert information about a message in the babyl file, without having
-to change the message itself.  In an mbox file, the only place to put
-such information is the message header, which is part of the message.
-Thus, adding information about a message to an mbox file means that one
-has to change the message.
-
-I think Gnus doesn't make use of this advantage, though.  Gnus stores
-information about messages in an extra file, @file{~/.newsrc.eld}.
-
-@end table
-
-@quotation
-CCC Can somebody provide me with some more arguments in favor of one of
-the formats?
-
-CCC Is it possible to just use an existing babyl file for Gnus, by
-creating a new nnmbox server and pointing it at the file?  What about
-mbox?
-@end quotation
-
-
-@subsection Backends with one file per group
-
-Storing all messages in a group in one file provides a nice middle
-ground between the one file per server type of backend and the one file
-per message type of backend.  Using lots of little files wastes disk
-space; since this approach uses a moderate number of files, less disk
-space is wasted.
-
-@quotation
-CCC Which operations are fast using this kind of backend?  Which are
-slow? 
-@end quotation
-
-@table @code
-@item nnfolder
-This backend uses the same file format as @code{nnmbox}, but uses the
-one file per group approach.
-
-@end table
-
-There is no ``nnbabylfolder'' backend which uses babyl format.
-
-
-@subsection Backends with one file per message
-
-If the number of messages grows so large that even the size of a single
-group exceeds the limit which can be handled by the file-per-group
-backends, you need to think about using one of the backends mentioned
-here.
-
-This category also includes @code{nnml}, the backend which is fastest if
-you have lots of messages.
-
-@table @code
-@item nnmh
-This backend uses the same file format (and directory structure) as MH,
-i.e.@ a group is a directory, and each message is stored in a file, and
-the file names are numbers.
-
-Since @code{nnml} is so similar to @code{nnmh} but a lot faster, only
-unusual situations could warrant using this backend.  You may want to
-use @code{nnmh} if you wish to use Gnus in parallel to your old MH based
-reader.
-
-Normally, you should not let two programs write the same Gnus directory
-(not even two instances of Gnus!), but if you really must, you may wish
-to use @code{nnmh}, since there the probability of things breaking is
-smaller than with the other backends.
-
-@item nnml
-This backend is like @code{nnmh} but also includes an extra file
-@file{.overview} in each directory (group) which contains some headers
-from each message.  Thus, where @code{nnmh} needs to open every file in
-a group to examine its headers, @code{nnml} (normally) needs to only
-read the @file{.overview} file, which is a lot faster.
-@end table
-
-
-@subsection Other mail backends
-
-There is one other mail backend, for keeping messages on an IMAP server.
-
-@table @code
-@item nnimap
-This backend transforms Gnus into an IMAP client.  The general idea of
-IMAP is to store and manipulate the mails on a server (similar to NNTP
-for news).
-
-@code{nnimap} only works with the current development version of Gnus,
-though.  See @url{http://www.extundo.com/nnimap/} for @code{nnimap} and
-see @url{http://www.gnus.org/} for Gnus.  Don't forget to subscribe to
-both the Gnus and the nnimap mailing lists since you are using alpha
-grade software which can be exptected to have bugs.  Be prepared to
-submit meaningful bug reports if you encounter bugs.
-
-Rumor has it that @code{nnimap} will be integrated with the next version
-of Gnus (version 5.8, presumably), when that comes out.
-
-@end table
-
-
-@subsection Summary
-
-If you must talk to an IMAP server, the choice is clear.  But if you
-keep mails on your local disk, the choice isn't as clear-cut.  I think
-that @code{nnml} is generally the best choice unless you have real great
-disk space trouble.  Then, you should be thinking about @code{nnfolder}.
-
-I'm not sure if there is a situation where @code{nnmbox} or
-@code{nnbabyl} is desirable.

-@section Auto-expire versus total-expire
-@c ------------------------------------------------------------
-
-Every now and then, people ask about auto-expire and total-expire.
-Since both of these features are means to the same end, and since they
-are similar and dissimilar at the same time, great confusion can result
-in the unsuspecting new Gnus user.  I'll try to explain how each works
-and which one to use.  However, be prepared that there will be no clear
-recommendation: both work well, so for many situations both are
-appropriate.  So it is more a matter of taste which one to choose.  And
-I can't help you with that!
-
-
-@subsection What is expiry?
-
-Gnus treats mail in a newsreaderly fashion, so it is useful to examine
-the situation for news.  Your news server periodically contacts other
-news servers and exchanges messages with the other server.  The two news
-servers exchange lists of messages, and messages present in one server
-but not in the other are sent to the other server.  This works in both
-directions.  Many connections between news servers exist, and this is
-the way how postings travel from you into the world: when you post a
-message, your news server stores it and offers it to the other servers
-in the message list exchanging phase.  Since the other servers aren't
-going to have the posting you just wrote, it gets transferred and
-finally can be seen all over the world.
-
-You can quickly see that new messages will be arriving at your news
-server, which stores them on disk.  So something has got to happen else
-the disk will fill up real fast.  That ``something'' is expiry: the
-oldest messages are deleted to make room for the new ones.  Normally, a
-news server can be configured on a per-group basis which messages should
-be deleted.  In some groups, messages might be deleted which are older
-than a day, in other groups, messages might be kept for a month.
-
-This means if you go on vacation then come back later to read news, you
-are likely to miss some postings if the expiration time for the groups
-you read is shorter than the time you were on vacation.
-
-How does that apply to mail?
-
-Well, mail should stay more under the control of the user than news is.
-When you come back from a vacation, you expect to see all messages
-arrived during that time, not only the recent ones!
-
-Because of this, Gnus offers you the @kbd{E} key.  This marks a message
-as expirable.  No mail is ever deleted from disk, unless it is
-expirable.  Every once in a while (by default, whenever you quit a group
-by hitting @kbd{q} in the Summary buffer), the expiry process is run,
-which goes through all expirable messages (of a group) and expires it if
-old enough.  By default, messages older than seven days are ``old
-enough''.  Seven days, that is, since it was marked as expirable.
-
-@quotation
-CCC Last sentence correct?
-@end quotation
-
-``But when I read a message, exit the group, then enter it again, the
-message is gone!''
-
-Right.  By default, Gnus hides messages which have already been read.
-If you are the keyboard type, you can hit @kbd{C-u @key{RET}} or
-@kbd{C-u @key{SPC}} to enter the group or @kbd{C-u M-g} when in the
-group to look at the read messages.  If you are the mousey type, you may
-wish to use the ``See old articles'' entry in the ``Group'' menu.
-
-@quotation
-CCC How does one code menu entries in TeXinfo?
-@end quotation
-
-
-@subsection Why auto-expire and total-expire?
-
-When reading mail, by default Gnus marks as read each message that you
-read.  If you want to mark it as expirable, you have to hit @kbd{E}.
-Many people are subscribed to mailing lists and they configure Gnus to
-put mails from a mailing list into their own group.  Most messages in
-such groups should be expirable, once read.  But hitting @kbd{E} all the
-gets old real quick.  Hence, auto-expire and total-expire were invented.
-
-
-@subsection Auto-expire vs.@ total-expire
-
-Auto-expire and total-expire both aim at the same goal: articles which
-are read should normally be expired, only if one does something special
-should these articles be saved on disk.  But what happens when a message
-is being read by you, the user?  Well, the message is marked as read
-(with the `R' mark).  So, what can be done to make these messages
-expire?  Well, two approaches come to mind: one idea is to change the
-mark that is attached to messages that you read, and the other idea is
-to make the `R' articles expirable.  These are @emph{exactly} the things
-that are done in Gnus: auto-expire means to change the mark that is
-attached to a message that is being read, and total-expire means to
-change the meaning of the `R' mark to mean expirable.
-
-A more precise description of auto-expire might be the following: If an
-article is unmarked and then selected for reading,@footnote{Using
-@kbd{g}, or @kbd{@key{mouse-2}}, or by moving to it with @kbd{n} or
-@kbd{p}, or by one of the many other methods provided by Gnus.} it is
-marked with `E', as if the user had hit @kbd{E}.
-
-It is important to realize that auto-expire has @emph{no other}
-consequences.  Selecting a message for reading which wasn't unmarked
-doesn't do anything special, and hitting @kbd{d} on a message also
-doesn't do anything special.  (It therefore marks the message as read,
-not as expirable!)
-
-Now, forget about auto-expire, empty your mind and prepare to learn
-about total-expire.  Like I said, total-expire changes what it means for
-an article to be marked as read.
-
-A more precise description of total-expire might be the following: When
-the expire process is run (for example, when you leave a group with
-@kbd{q}), all messages marked as read are considered to be expirable, as
-if they had been marked with `E'.  Recall that there are several ways to
-mark a message as read: by reading it, by hitting @kbd{d} on it, and in
-a few other ways which I haven't mentioned so far.  Recall that, in
-addition to the messages marked with `R', also those marked with `r' or
-`O' are considered to be marked as read.
-
-Can auto-expire and total-expire be used together?  Well, in principle
-they can, but that doesn't make sense.  Just using total-expire alone
-achieves the same effect.
-
-So, how do auto-expire and total-expire compare?  Well, for once thing,
-hitting @kbd{d} on a message means it is expirable if total-expire is
-on (since it is marked as read and all messages marked as read are
-considered expirable when total-expire is on), but it is not expirable
-if auto-expire is on (since it is marked as read and only articles
-marked expirable (`E') are considered to be expirable).  If you want to
-mark a message as expirable when total-expire is off, use @kbd{E}.
-
-One way of comparing auto-expire and total-expire is to compare the
-message marks that are available, and what they mean.  Since auto-expire
-does not change the meaning of marks, its behavior is the same as in the
-default case.  It's only important whether total-expire is on or off.
-Thus, there are only two cases: the default case and the total-expire
-case.
-
-@subsubsection Article marks with and without total-expire
-
-The following are the default article marks and behavior:
-
-@table @dfn
-@item unmarked
-All new messages are unmarked.  This means you haven't seen them.  They
-are always shown and won't be deleted.
-
-@item read
-Messages marked as read are not shown by default but kept on disk till
-hell freezes over.  You can show them with @kbd{C-u M-g} from the
-summary buffer, or with @kbd{C-u @key{SPC}} or with the `Group' menu
-item `See old articles' from the group buffer.
-
-Depending on the setting of @var{gnus-fetch-old-headers}, a message
-marked as read might be shown if there is a followup or reply to it.
-
-@item dormant
-Dormant messages aren't shown by default but kept on disk till hell
-freezes over.  You can show them with @kbd{/ D} from the summary buffer.
-If there is a reply or followup to a dormant message, the dormant
-message is also shown.
-
-@item ticked
-Ticked messages are always shown and kept on disk till hell freezes
-over.
-
-@item expirable
-Expirable messages will be deleted in due time.  They are not shown by
-default, but you can make them appear with @kbd{C-u M-g} and so on,
-similar to the read ones.
-
-@end table
-
-Please note that the behavior for ticked messages is similar to the
-unread ones, and that the behavior of dormant messages is similar to the
-read ones.  Especially the second fact will become important when we
-look at
-
-The behavior of the article marks with total-expire:
-
-@table @dfn
-@item unmarked
-Same as in the default case.
-
-@item expirable
-Same as in the default case.
-
-@item read
-Same as expirable.
-
-@item dormant
-Same as in the default case.
-
-@item ticked
-Same as in the default case.
-
-@end table
-
-As you can see, only the behavior of the read messages is different, and
-you can use the dormant mark if you want to achieve behavior similar to
-the behavior of read messages in the default case.
-
-
-@subsubsection Speed issues
-
-Total-expire may be slow when expiry happens.  Why is that?  Well, Gnus
-keeps an explicit list of all expirable messages (the ones marked `E'
-without taking total-expire into account), as well as a list of dormant
-messages, and a list of ticked messages.  Normally, when expiration time
-comes, Gnus goes through all articles in the expire list and looks if
-they are old enough to be expired.
-
-However, for read messages the situation is different.  Here, Gnus just
-keeps a list of ranges of article numbers to be able to distinguish read
-messages from unmarked ones.  The assumption is that a message is to be
-considered marked as read if it falls in one of the ranges and isn't
-mentioned in any of the expirable, dormant or ticked lists.
-
-When total-expire is turned on, Gnus needs to go through all messages in
-the read range in order to look if it's in one of the lists.  If the
-message is not in the ticked or dormant list, it is expirable and thus
-Gnus looks to see if it is old enough.
-
-Obviously, going through all the articles in the read ranges takes more
-time than going through just the list of expirable articles.
-
-Something can be done about the speed issue, though.  Normally, the
-expiry process is started whenever you leave a group.  I suggest that
-you disable this and instead run expiry just once per day, for example
-while you are going for lunch.  This means that expiry still takes a
-long time, but you don't see it and thus it doesn't bother you.
-
-Here's how to do that: You disable the expire-on-group-exit thing with
-the following line in your @file{~/.gnus} file:
-@lisp
-(remove-hook 'gnus-summary-prepare-exit-hook
-             'gnus-summary-expire-articles)
-@end lisp
-And before you leave for lunch, you hit @kbd{C-M-x}, or @kbd{M-x
-gnus-group-expire-all-groups @key{RET}}.
-
-
-@subsubsection Functionality
-
-Adaptive scoring doesn't work with auto-expire.  (But normal scoring
-still works fine.)  Adaptive scoring works fine with total-expire.
-
-
-@subsubsection A summary
-
-Well, it is difficult to sum up the whole discussion.  I used to use
-total-expire but have switched to auto-expire a long time ago.  I liked
-the fact that I could use one more kind of article mark.  I also liked
-the fact that marking a message as read works the same in auto-expirable
-groups and in normal mail groups: you hit @kbd{E}.  (With total-expire,
-you normally hit @kbd{d} but must remember to use @kbd{E} for those
-groups where total-expire is off.)  And I liked that auto-expire is
-faster.
-
-On the other hand, adaptive scoring is surely a very useful feature (I'm
-just beginning to use it), so many people might prefer total-expire.
-
-And on a third hand, maybe the key binding issue isn't so important
-after all.  You see, in mail groups the @kbd{d} key means `keep this
-message for archival purposes', whereas in many other modes (dired, CCC
-others?) it stands for `delete'.  I propose to make it mean delete in
-mail groups, too, with the following line in
-@file{~/.gnus}:@footnote{See the chapter on key bindings; maybe you need
-a `require' statement.}
-@lisp
-(define-key gnus-summary-mode-map "d" 'gnus-summary-mark-as-expirable)
-@end lisp
-Marking messages as expirable (rather than read) in news groups does no
-harm, nor does it harm to do so in total-expirable mail groups.  The old
-`keep this message' semantics can still be had by marking a message as
-dormant or by using @kbd{M r} (in non-total-expirable groups only).

-@section Migrating old mail
-@c ------------------------------------------------------------

-Probably, you've been reading mail in pre-Gnus times, right?  And surely
-you wish to carry this over to Gnus.  Well, I haven't found a real good
-way to do it, but I can offer a few suggestions for doing it at least
-semi-automatically.
-
-One way of getting at your old mail is to type @kbd{G f}, and to then
-enter the name of your old mail file.  This provides read-only access to
-your mails.  For some people, this might be sufficient.  (With @kbd{G
-f}, you have created an @code{nndoc} group.)
-
-Some people might want to have their mails available in their normal
-mail groups hierarchy.  That's simple, just create an @code{nndoc} group
-for your mail file, then mark all messages in it with @kbd{M P a}, then
-copy all of them over to a normal mail group, with @kbd{B c}.
-
-This is good for people who wish to keep their old arrangement of
-folders, and who have a one-to-one correspondence between old mail files
-and new Gnus groups.  But some people might wish to split up their mails
-differently.  For them, it might be useful to set up
-@var{nnmail-split-methods} correctly and to use @kbd{B r} instead of
-@kbd{B c}.  This goes through all process-marked messages and subjects
-them to the same splitting process that newly arriving messages go
-through.  (Whee!  What a run-on sentence!)

-
-@ifinfo
-
-You can read news (and mail) from within Emacs by using Gnus.  The news
-can be gotten by any nefarious means you can think of---@sc{nntp}, local
-spool or your mbox file.  All at the same time, if you want to push your
-luck.
-
-This manual corresponds to Pterodactyl Gnus .
-
-@end ifinfo

-@iftex
-
-
-Gnus is the advanced, self-documenting, customizable, extensible
-unreal-time newsreader for GNU Emacs.
-
-Oops.  That sounds oddly familiar, so let's start over again to avoid
-being accused of plagiarism:
-
-Gnus is a message-reading laboratory.  It will let you look at just
-about anything as if it were a newsgroup.  You can read mail with it,
-you can browse directories with it, you can @code{ftp} with it---you can
-even read news with it!
-
-Gnus tries to empower people who read news the same way Emacs empowers
-people who edit text.  Gnus sets no limits to what the user should be
-allowed to do.  Users are encouraged to extend Gnus to make it behave
-like they want it to behave.  A program should not control people;
-people should be empowered to do what they want by using (or abusing)
-the program.

-@vindex gnus-select-method
-@c @head
-The @code{gnus-select-method} variable says where Gnus should look for
-news.  This variable should be a list where the first element says
-@dfn{how} and the second element says @dfn{where}.  This method is your
-native method.  All groups not fetched with this method are
-foreign groups.
-
-For instance, if the @samp{news.somewhere.edu} @sc{nntp} server is where
-you want to get your daily dosage of news from, you'd say:
-
-@lisp
-(setq gnus-select-method '(nntp "news.somewhere.edu"))
-@end lisp
-
-If you want to read directly from the local spool, say:
-
-@lisp
-(setq gnus-select-method '(nnspool ""))
-@end lisp
-
-If you can use a local spool, you probably should, as it will almost
-certainly be much faster.
-
-@vindex gnus-nntpserver-file
-@cindex NNTPSERVER
-@cindex @sc{nntp} server
-If this variable is not set, Gnus will take a look at the
-@code{NNTPSERVER} environment variable.  If that variable isn't set,
-Gnus will see whether @code{gnus-nntpserver-file}
-(@file{/etc/nntpserver} by default) has any opinions on the matter.  If
-that fails as well, Gnus will try to use the machine running Emacs as an @sc{nntp} server.  That's a long shot, though.
-
-@vindex gnus-nntp-server
-If @code{gnus-nntp-server} is set, this variable will override
-@code{gnus-select-method}.  You should therefore set
-@code{gnus-nntp-server} to @code{nil}, which is what it is by default.
-
-@vindex gnus-secondary-servers
-@vindex gnus-nntp-server
-You can also make Gnus prompt you interactively for the name of an
-@sc{nntp} server.  If you give a non-numerical prefix to @code{gnus}
-(i.e., @kbd{C-u M-x gnus}), Gnus will let you choose between the servers
-in the @code{gnus-secondary-servers} list (if any).  You can also just
-type in the name of any server you feel like visiting.  (Note that this
-will set @code{gnus-nntp-server}, which means that if you then @kbd{M-x
-gnus} later in the same Emacs session, Gnus will contact the same
-server.)
-
-@findex gnus-group-browse-foreign-server
-@kindex B (Group)
-However, if you use one @sc{nntp} server regularly and are just
-interested in a couple of groups from a different server, you would be
-better served by using the @kbd{B} command in the group buffer.  It will
-let you have a look at what groups are available, and you can subscribe
-to any of the groups you want to.  This also makes @file{.newsrc}
-maintenance much tidier.  @xref{Foreign Groups}.
-
-@vindex gnus-secondary-select-methods
-@c @head
-A slightly different approach to foreign groups is to set the
-@code{gnus-secondary-select-methods} variable.  The select methods
-listed in this variable are in many ways just as native as the
-@code{gnus-select-method} server.  They will also be queried for active
-files during startup (if that's required), and new newsgroups that
-appear on these servers will be subscribed (or not) just as native
-groups are.
-
-For instance, if you use the @code{nnmbox} backend to read your mail, you
-would typically set this variable to
-
-@lisp
-(setq gnus-secondary-select-methods '((nnmbox "")))
-@end lisp
-
-
-@node The First Time
-@section The First Time
-@cindex first time usage
-
-If no startup files exist, Gnus will try to determine what groups should
-be subscribed by default.
-
-@vindex gnus-default-subscribed-newsgroups
-If the variable @code{gnus-default-subscribed-newsgroups} is set, Gnus
-will subscribe you to just those groups in that list, leaving the rest
-killed.  Your system administrator should have set this variable to
-something useful.
-
-Since she hasn't, Gnus will just subscribe you to a few arbitrarily
-picked groups (i.e., @samp{*.newusers}).  (@dfn{Arbitrary} is defined
-here as @dfn{whatever Lars thinks you should read}.)
-
-You'll also be subscribed to the Gnus documentation group, which should
-help you with most common problems.
-
-If @code{gnus-default-subscribed-newsgroups} is @code{t}, Gnus will just
-use the normal functions for handling new groups, and not do anything
-special.
-
-
-@node The Server is Down
-@section The Server is Down
-@cindex server errors
-
-If the default server is down, Gnus will understandably have some
-problems starting.  However, if you have some mail groups in addition to
-the news groups, you may want to start Gnus anyway.
-
-Gnus, being the trusting sort of program, will ask whether to proceed
-without a native select method if that server can't be contacted.  This
-will happen whether the server doesn't actually exist (i.e., you have
-given the wrong address) or the server has just momentarily taken ill
-for some reason or other.  If you decide to continue and have no foreign
-groups, you'll find it difficult to actually do anything in the group
-buffer.  But, hey, that's your problem.  Blllrph!
-
-@findex gnus-no-server
-@kindex M-x gnus-no-server
-@c @head
-If you know that the server is definitely down, or you just want to read
-your mail without bothering with the server at all, you can use the
-@code{gnus-no-server} command to start Gnus.  That might come in handy
-if you're in a hurry as well.  This command will not attempt to contact
-your primary server---instead, it will just activate all groups on level
-1 and 2.  (You should preferably keep no native groups on those two
-levels.)
-
-
-@node Slave Gnusae
-@section Slave Gnusae
-@cindex slave
-
-You might want to run more than one Emacs with more than one Gnus at the
-same time.  If you are using different @file{.newsrc} files (e.g., if you
-are using the two different Gnusae to read from two different servers),
-that is no problem whatsoever.  You just do it.
-
-The problem appears when you want to run two Gnusae that use the same
-@code{.newsrc} file.
-
-To work around that problem some, we here at the Think-Tank at the Gnus
-Towers have come up with a new concept: @dfn{Masters} and
-@dfn{slaves}.  (We have applied for a patent on this concept, and have
-taken out a copyright on those words.  If you wish to use those words in
-conjunction with each other, you have to send $1 per usage instance to
-me.  Usage of the patent (@dfn{Master/Slave Relationships In Computer
-Applications}) will be much more expensive, of course.)
-
-Anyways, you start one Gnus up the normal way with @kbd{M-x gnus} (or
-however you do it).  Each subsequent slave Gnusae should be started with
-@kbd{M-x gnus-slave}.  These slaves won't save normal @file{.newsrc}
-files, but instead save @dfn{slave files} that contain information only
-on what groups have been read in the slave session.  When a master Gnus
-starts, it will read (and delete) these slave files, incorporating all
-information from them.  (The slave files will be read in the sequence
-they were created, so the latest changes will have precedence.)
-
-Information from the slave files has, of course, precedence over the
-information in the normal (i.e., master) @code{.newsrc} file.

-
-@node Checking New Groups
-@subsection Checking New Groups
-
-Gnus normally determines whether a group is new or not by comparing the
-list of groups from the active file(s) with the lists of subscribed and
-dead groups.  This isn't a particularly fast method.  If
-@code{gnus-check-new-newsgroups} is @code{ask-server}, Gnus will ask the
-server for new groups since the last time.  This is both faster and
-cheaper.  This also means that you can get rid of the list of killed
-groups altogether, so you may set @code{gnus-save-killed-list} to
-@code{nil}, which will save time both at startup, at exit, and all over.
-Saves disk space, too.  Why isn't this the default, then?
-Unfortunately, not all servers support this command.
-
-I bet I know what you're thinking now: How do I find out whether my
-server supports @code{ask-server}?  No?  Good, because I don't have a
-fail-safe answer.  I would suggest just setting this variable to
-@code{ask-server} and see whether any new groups appear within the next
-few days.  If any do, then it works.  If none do, then it doesn't
-work.  I could write a function to make Gnus guess whether the server
-supports @code{ask-server}, but it would just be a guess.  So I won't.
-You could @code{telnet} to the server and say @code{HELP} and see
-whether it lists @samp{NEWGROUPS} among the commands it understands.  If
-it does, then it might work.  (But there are servers that lists
-@samp{NEWGROUPS} without supporting the function properly.)
-
-This variable can also be a list of select methods.  If so, Gnus will
-issue an @code{ask-server} command to each of the select methods, and
-subscribe them (or not) using the normal methods.  This might be handy
-if you are monitoring a few servers for new groups.  A side effect is
-that startup will take much longer, so you can meditate while waiting.
-Use the mantra ``dingnusdingnusdingnus'' to achieve permanent bliss.
-
-
-@node Subscription Methods
-@subsection Subscription Methods
-
-@vindex gnus-subscribe-newsgroup-method
-What Gnus does when it encounters a new group is determined by the
-@code{gnus-subscribe-newsgroup-method} variable.
-
-This variable should contain a function.  This function will be called
-with the name of the new group as the only parameter.
-
-Some handy pre-fab functions are:
-
-@table @code
-
-@item gnus-subscribe-zombies
-@vindex gnus-subscribe-zombies
-Make all new groups zombies.  This is the default.  You can browse the
-zombies later (with @kbd{A z}) and either kill them all off properly
-(with @kbd{S z}), or subscribe to them (with @kbd{u}).
-
-@item gnus-subscribe-randomly
-@vindex gnus-subscribe-randomly
-Subscribe all new groups in arbitrary order.  This really means that all
-new groups will be added at ``the top'' of the group buffer.
-
-@item gnus-subscribe-alphabetically
-@vindex gnus-subscribe-alphabetically
-Subscribe all new groups in alphabetical order.
-
-@item gnus-subscribe-hierarchically
-@vindex gnus-subscribe-hierarchically
-Subscribe all new groups hierarchically.  The difference between this
-function and @code{gnus-subscribe-alphabetically} is slight.
-@code{gnus-subscribe-alphabetically} will subscribe new groups in a strictly
-alphabetical fashion, while this function will enter groups into its
-hierarchy.  So if you want to have the @samp{rec} hierarchy before the
-@samp{comp} hierarchy, this function will not mess that configuration
-up.  Or something like that.
-
-@item gnus-subscribe-interactively
-@vindex gnus-subscribe-interactively
-Subscribe new groups interactively.  This means that Gnus will ask
-you about @strong{all} new groups.  The groups you choose to subscribe
-to will be subscribed hierarchically.
-
-@item gnus-subscribe-killed
-@vindex gnus-subscribe-killed
-Kill all new groups.
-
-@item gnus-subscribe-topics
-@vindex gnus-subscribe-topics
-Put the groups into the topic that has a matching @code{subscribe} topic 
-parameter (@pxref{Topic Parameters}).  For instance, a @code{subscribe}
-topic parameter that looks like
-
-@example
-"nnslashdot"
-@end example
-
-will mean that all groups that match that regex will be subscribed under 
-that topic.
-
-@end table
-
-@vindex gnus-subscribe-hierarchical-interactive
-A closely related variable is
-@code{gnus-subscribe-hierarchical-interactive}.  (That's quite a
-mouthful.)  If this variable is non-@code{nil}, Gnus will ask you in a
-hierarchical fashion whether to subscribe to new groups or not.  Gnus
-will ask you for each sub-hierarchy whether you want to descend the
-hierarchy or not.
-
-One common mistake is to set the variable a few paragraphs above
-(@code{gnus-subscribe-newsgroup-method}) to
-@code{gnus-subscribe-hierarchical-interactive}.  This is an error.  This
-will not work.  This is ga-ga.  So don't do it.
-
-
-@node Filtering New Groups
-@subsection Filtering New Groups
-
-A nice and portable way to control which new newsgroups should be
-subscribed (or ignored) is to put an @dfn{options} line at the start of
-the @file{.newsrc} file.  Here's an example:
-
-@example
-options -n !alt.all !rec.all sci.all
-@end example
-
-@vindex gnus-subscribe-options-newsgroup-method
-This line obviously belongs to a serious-minded intellectual scientific
-person (or she may just be plain old boring), because it says that all
-groups that have names beginning with @samp{alt} and @samp{rec} should
-be ignored, and all groups with names beginning with @samp{sci} should
-be subscribed.  Gnus will not use the normal subscription method for
-subscribing these groups.
-@code{gnus-subscribe-options-newsgroup-method} is used instead.  This
-variable defaults to @code{gnus-subscribe-alphabetically}.
-
-@vindex gnus-options-not-subscribe
-@vindex gnus-options-subscribe
-If you don't want to mess with your @file{.newsrc} file, you can just
-set the two variables @code{gnus-options-subscribe} and
-@code{gnus-options-not-subscribe}.  These two variables do exactly the
-same as the @file{.newsrc} @samp{options -n} trick.  Both are regexps,
-and if the new group matches the former, it will be unconditionally
-subscribed, and if it matches the latter, it will be ignored.
-
-@vindex gnus-auto-subscribed-groups
-Yet another variable that meddles here is
-@code{gnus-auto-subscribed-groups}.  It works exactly like
-@code{gnus-options-subscribe}, and is therefore really superfluous, but I
-thought it would be nice to have two of these.  This variable is more
-meant for setting some ground rules, while the other variable is used
-more for user fiddling.  By default this variable makes all new groups
-that come from mail backends (@code{nnml}, @code{nnbabyl},
-@code{nnfolder}, @code{nnmbox}, and @code{nnmh}) subscribed.  If you
-don't like that, just set this variable to @code{nil}.
-
-New groups that match this regexp are subscribed using
-@code{gnus-subscribe-options-newsgroup-method}.

-@node Changing Servers
-@section Changing Servers
-@cindex changing servers
-
-Sometimes it is necessary to move from one @sc{nntp} server to another.
-This happens very rarely, but perhaps you change jobs, or one server is
-very flaky and you want to use another.
-
-Changing the server is pretty easy, right?  You just change
-@code{gnus-select-method} to point to the new server?
-
-@emph{Wrong!}
-
-Article numbers are not (in any way) kept synchronized between different
-@sc{nntp} servers, and the only way Gnus keeps track of what articles
-you have read is by keeping track of article numbers.  So when you
-change @code{gnus-select-method}, your @file{.newsrc} file becomes
-worthless.
-
-Gnus provides a few functions to attempt to translate a @file{.newsrc}
-file from one server to another.  They all have one thing in
-common---they take a looong time to run.  You don't want to use these
-functions more than absolutely necessary.
-
-@kindex M-x gnus-change-server
-@findex gnus-change-server
-If you have access to both servers, Gnus can request the headers for all
-the articles you have read and compare @code{Message-ID}s and map the
-article numbers of the read articles and article marks.  The @kbd{M-x
-gnus-change-server} command will do this for all your native groups.  It
-will prompt for the method you want to move to.
-
-@kindex M-x gnus-group-move-group-to-server
-@findex gnus-group-move-group-to-server
-You can also move individual groups with the @kbd{M-x
-gnus-group-move-group-to-server} command.  This is useful if you want to
-move a (foreign) group from one server to another.
-
-@kindex M-x gnus-group-clear-data-on-native-groups
-@findex gnus-group-clear-data-on-native-groups
-If you don't have access to both the old and new server, all your marks
-and read ranges have become worthless.  You can use the @kbd{M-x
-gnus-group-clear-data-on-native-groups} command to clear out all data
-that you have on your native groups.  Use with caution.
-
-After changing servers, you @strong{must} move the cache hierarchy away,
-since the cached articles will have wrong article numbers, which will
-affect which articles Gnus thinks are read.

-the @file{.newsrc} file.)  @sc{gnus} would read whichever one of these
-files was the most recently saved, which enabled people to swap between
-@sc{gnus} and other newsreaders.
-
-That was kinda silly, so Gnus went one better: In addition to the
-@file{.newsrc} and @file{.newsrc.el} files, Gnus also has a file called
-@file{.newsrc.eld}.  It will read whichever of these files that are most
-recent, but it will never write a @file{.newsrc.el} file.  You should
-never delete the @file{.newsrc.eld} file---it contains much information
-not stored in the @file{.newsrc} file.
-
-@vindex gnus-save-newsrc-file
-@vindex gnus-read-newsrc-file
-You can turn off writing the @file{.newsrc} file by setting
-@code{gnus-save-newsrc-file} to @code{nil}, which means you can delete
-the file and save some space, as well as exiting from Gnus faster.
-However, this will make it impossible to use other newsreaders than
-Gnus.  But hey, who would want to, right?  Similarly, setting
-@code{gnus-read-newsrc-file} to @code{nil} makes Gnus ignore the
-@file{.newsrc} file and any @file{.newsrc-SERVER} files, which is
-convenient if you have a tendency to use Netscape once in a while.
-
-@vindex gnus-save-killed-list
-If @code{gnus-save-killed-list} (default @code{t}) is @code{nil}, Gnus
-will not save the list of killed groups to the startup file.  This will
-save both time (when starting and quitting) and space (on disk).  It
-will also mean that Gnus has no record of what groups are new or old,
-so the automatic new groups subscription methods become meaningless.
-You should always set @code{gnus-check-new-newsgroups} to @code{nil} or
-@code{ask-server} if you set this variable to @code{nil} (@pxref{New
-Groups}).  This variable can also be a regular expression.  If that's
-the case, remove all groups that do not match this regexp before
-saving.  This can be useful in certain obscure situations that involve
-several servers where not all servers support @code{ask-server}.
-
-@vindex gnus-startup-file
-The @code{gnus-startup-file} variable says where the startup files are.
-The default value is @file{~/.newsrc}, with the Gnus (El Dingo) startup
-file being whatever that one is, with a @samp{.eld} appended.
-
-@vindex gnus-save-newsrc-hook
-@vindex gnus-save-quick-newsrc-hook
-@vindex gnus-save-standard-newsrc-hook
-@code{gnus-save-newsrc-hook} is called before saving any of the newsrc
-files, while @code{gnus-save-quick-newsrc-hook} is called just before
-saving the @file{.newsrc.eld} file, and
-@code{gnus-save-standard-newsrc-hook} is called just before saving the
-@file{.newsrc} file.  The latter two are commonly used to turn version
-control on or off.  Version control is on by default when saving the
-startup files.  If you want to turn backup creation off, say something like:
-
-@lisp
-(defun turn-off-backup ()
-  (set (make-local-variable 'backup-inhibited) t))
-
-(add-hook 'gnus-save-quick-newsrc-hook 'turn-off-backup)
-(add-hook 'gnus-save-standard-newsrc-hook 'turn-off-backup)
-@end lisp
-
-@vindex gnus-init-file
-When Gnus starts, it will read the @code{gnus-site-init-file}
-(@file{.../site-lisp/gnus} by default) and @code{gnus-init-file}
-(@file{~/.gnus} by default) files.  These are normal Emacs Lisp files
-and can be used to avoid cluttering your @file{~/.emacs} and
-@file{site-init} files with Gnus stuff.  Gnus will also check for files
-with the same names as these, but with @file{.elc} and @file{.el}
-suffixes.  In other words, if you have set @code{gnus-init-file} to
-@file{~/.gnus}, it will look for @file{~/.gnus.elc}, @file{~/.gnus.el},
-and finally @file{~/.gnus} (in this order).
-
-
-
-@node Auto Save
-@section Auto Save
-@cindex dribble file
-@cindex auto-save
-
-Whenever you do something that changes the Gnus data (reading articles,
-catching up, killing/subscribing groups), the change is added to a
-special @dfn{dribble buffer}.  This buffer is auto-saved the normal
-Emacs way.  If your Emacs should crash before you have saved the
-@file{.newsrc} files, all changes you have made can be recovered from
-this file.
-
-If Gnus detects this file at startup, it will ask the user whether to
-read it.  The auto save file is deleted whenever the real startup file is
-saved.
-
-@vindex gnus-use-dribble-file
-If @code{gnus-use-dribble-file} is @code{nil}, Gnus won't create and
-maintain a dribble buffer.  The default is @code{t}.
-
-@vindex gnus-dribble-directory
-Gnus will put the dribble file(s) in @code{gnus-dribble-directory}.  If
-this variable is @code{nil}, which it is by default, Gnus will dribble
-into the directory where the @file{.newsrc} file is located.  (This is
-normally the user's home directory.)  The dribble file will get the same
-file permissions as the @code{.newsrc} file.
-
-@vindex gnus-always-read-dribble-file
-If @code{gnus-always-read-dribble-file} is non-@code{nil}, Gnus will
-read the dribble file on startup without querying the user.
-
-
-@node The Active File
-@section The Active File
-@cindex active file
-@cindex ignored groups
-
-When Gnus starts, or indeed whenever it tries to determine whether new
-articles have arrived, it reads the active file.  This is a very large
-file that lists all the active groups and articles on the server.
-
-@vindex gnus-ignored-newsgroups
-Before examining the active file, Gnus deletes all lines that match the
-regexp @code{gnus-ignored-newsgroups}.  This is done primarily to reject
-any groups with bogus names, but you can use this variable to make Gnus
-ignore hierarchies you aren't ever interested in.  However, this is not
-recommended.  In fact, it's highly discouraged.  Instead, @pxref{New
-Groups} for an overview of other variables that can be used instead.
-
-@c This variable is
-@c @code{nil} by default, and will slow down active file handling somewhat
-@c if you set it to anything else.
-
-@vindex gnus-read-active-file
-@c @head
-The active file can be rather Huge, so if you have a slow network, you
-can set @code{gnus-read-active-file} to @code{nil} to prevent Gnus from
-reading the active file.  This variable is @code{some} by default.
-
-Gnus will try to make do by getting information just on the groups that
-you actually subscribe to.
-
-Note that if you subscribe to lots and lots of groups, setting this
-variable to @code{nil} will probably make Gnus slower, not faster.  At
-present, having this variable @code{nil} will slow Gnus down
-considerably, unless you read news over a 2400 baud modem.
-
-This variable can also have the value @code{some}.  Gnus will then
-attempt to read active info only on the subscribed groups.  On some
-servers this is quite fast (on sparkling, brand new INN servers that
-support the @code{LIST ACTIVE group} command), on others this isn't fast
-at all.  In any case, @code{some} should be faster than @code{nil}, and
-is certainly faster than @code{t} over slow lines.
-
-Some news servers (Leafnode and old versions of INN, for instance) do
-not support the @code{LIST ACTIVE group}.  For these servers, @code{nil}
-is probably the most efficient value for this variable.
-
-If this variable is @code{nil}, Gnus will ask for group info in total
-lock-step, which isn't very fast.  If it is @code{some} and you use an
-@sc{nntp} server, Gnus will pump out commands as fast as it can, and
-read all the replies in one swoop.  This will normally result in better
-performance, but if the server does not support the aforementioned
-@code{LIST ACTIVE group} command, this isn't very nice to the server.
-
-If you think that starting up Gnus takes too long, try all the three
-different values for this variable and see what works best for you. 
-
-In any case, if you use @code{some} or @code{nil}, you should definitely
-kill all groups that you aren't interested in to speed things up.
-
-Note that this variable also affects active file retrieval from
-secondary select methods.

-@file{.newsrc} file, but doesn't exist on the news server.  Checking for
-bogus groups can take quite a while, so to save time and resources it's
-best to leave this option off, and do the checking for bogus groups once
-in a while from the group buffer instead (@pxref{Group Maintenance}).
-
-@item gnus-inhibit-startup-message
-@vindex gnus-inhibit-startup-message
-If non-@code{nil}, the startup message won't be displayed.  That way,
-your boss might not notice as easily that you are reading news instead
-of doing your job.  Note that this variable is used before
-@file{.gnus.el} is loaded, so it should be set in @code{.emacs} instead.

-@cindex group buffer format
-
-The default format of the group buffer is nice and dull, but you can
-make it as exciting and ugly as you feel like.
-
-Here's a couple of example group lines:
-
-@example
-     25: news.announce.newusers
- *    0: alt.fan.andrea-dworkin
-@end example
-
-Quite simple, huh?
-
-You can see that there are 25 unread articles in
-@samp{news.announce.newusers}.  There are no unread articles, but some
-ticked articles, in @samp{alt.fan.andrea-dworkin} (see that little
-asterisk at the beginning of the line?).
-
-@vindex gnus-group-line-format
-You can change that format to whatever you want by fiddling with the
-@code{gnus-group-line-format} variable.  This variable works along the
-lines of a @code{format} specification, which is pretty much the same as
-a @code{printf} specifications, for those of you who use (feh!) C.
-@xref{Formatting Variables}.
-
-@samp{%M%S%5y: %(%g%)\n} is the value that produced those lines above.
-
-There should always be a colon on the line; the cursor always moves to
-the colon after performing an operation.  Nothing else is required---not
-even the group name.  All displayed text is just window dressing, and is
-never examined by Gnus.  Gnus stores all real information it needs using
-text properties.
-
-(Note that if you make a really strange, wonderful, spreadsheet-like
-layout, everybody will believe you are hard at work with the accounting
-instead of wasting time reading news.)
-
-Here's a list of all available format characters:
-
-@table @samp
-
-@item M
-An asterisk if the group only has marked articles.
-
-@item S
-Whether the group is subscribed.
-
-@item L
-Level of subscribedness.
-
-@item N
-Number of unread articles.
-
-@item I
-Number of dormant articles.
-
-@item T
-Number of ticked articles.
-
-@item R
-Number of read articles.
-
-@item t
-Estimated total number of articles.  (This is really @var{max-number}
-minus @var{min-number} plus 1.)
-
-@item y
-Number of unread, unticked, non-dormant articles.
-
-@item i
-Number of ticked and dormant articles.
-

-A string that looks like @samp{<%s:%n>} if a foreign select method is
-used.
-
-@item P
-Indentation based on the level of the topic (@pxref{Group Topics}).
-
-@item c
-@vindex gnus-group-uncollapsed-levels
-Short (collapsed) group name.  The @code{gnus-group-uncollapsed-levels}
-variable says how many levels to leave at the end of the group name.
-The default is 1---this will mean that group names like
-@samp{gnu.emacs.gnus} will be shortened to @samp{g.e.gnus}.
-
-@item m
-@vindex gnus-new-mail-mark
-@cindex %
-@samp{%} (@code{gnus-new-mail-mark}) if there has arrived new mail to
-the group lately.
-
-@item d
-A string that says when you last read the group (@pxref{Group
-Timestamp}).
-
-@item u
-User defined specifier.  The next character in the format string should
-be a letter.  Gnus will call the function
-@code{gnus-user-format-function-}@samp{X}, where @samp{X} is the letter
-following @samp{%u}.  The function will be passed a single dummy
-parameter as argument.  The function should return a string, which will
-be inserted into the buffer just like information from any other
-specifier.
-@end table

-@findex gnus-group-read-group
-Select the current group, switch to the summary buffer and display the
-first unread article (@code{gnus-group-read-group}).  If there are no
-unread articles in the group, or if you give a non-numerical prefix to
-this command, Gnus will offer to fetch all the old articles in this
-group from the server.  If you give a numerical prefix @var{N}, @var{N}
-determines the number of articles Gnus will fetch.  If @var{N} is
-positive, Gnus fetches the @var{N} newest articles, if @var{N} is

-
-@item RET
-@kindex RET (Group)
-@findex gnus-group-select-group
-Select the current group and switch to the summary buffer
-(@code{gnus-group-select-group}).  Takes the same arguments as
-@code{gnus-group-read-group}---the only difference is that this command
-does not display the first unread article automatically upon group
-entry.
-
-@item M-RET
-@kindex M-RET (Group)
-@findex gnus-group-quick-select-group
-This does the same as the command above, but tries to do it with the
-minimum amount of fuzz (@code{gnus-group-quick-select-group}).  No
-scoring/killing will be performed, there will be no highlights and no
-expunging.  This might be useful if you're in a real hurry and have to
-enter some humongous group.  If you give a 0 prefix to this command
-(i.e., @kbd{0 M-RET}), Gnus won't even generate the summary buffer,
-which is useful if you want to toggle threading before generating the
-summary buffer (@pxref{Summary Generation Commands}).
-
-@item M-SPACE
-@kindex M-SPACE (Group)
-@findex gnus-group-visible-select-group
-This is yet one more command that does the same as the @kbd{RET}
-command, but this one does it without expunging and hiding dormants
-(@code{gnus-group-visible-select-group}).
-
-@item M-C-RET
-@kindex M-C-RET (Group)
-@findex gnus-group-select-group-ephemerally
-Finally, this command selects the current group ephemerally without
-doing any processing of its contents
-(@code{gnus-group-select-group-ephemerally}).  Even threading has been
-turned off.  Everything you do in the group after selecting it in this
-manner will have no permanent effects.

-The @code{gnus-large-newsgroup} variable says what Gnus should consider
-to be a big group.  This is 200 by default.  If the group has more
-(unread and/or ticked) articles than this, Gnus will query the user
-before entering the group.  The user can then specify how many articles
-should be fetched from the server.  If the user specifies a negative
-number (@code{-n}), the @code{n} oldest articles will be fetched.  If it
-is positive, the @code{n} articles that have arrived most recently will
-be fetched.
-
-@vindex gnus-select-group-hook
-@vindex gnus-auto-select-first
-@code{gnus-auto-select-first} control whether any articles are selected

-can ask Gnus to just list groups on a given level or lower
-(@pxref{Listing Groups}), or to just check for new articles in groups on

-@vindex gnus-level-subscribed
-Gnus considers groups from levels 1 to
-@code{gnus-level-subscribed} (inclusive) (default 5) to be subscribed,
-@code{gnus-level-subscribed} (exclusive) and
-@code{gnus-level-unsubscribed} (inclusive) (default 7) to be
-unsubscribed, @code{gnus-level-zombie} to be zombies (walking dead)
-(default 8) and @code{gnus-level-killed} to be killed (completely dead)
-(default 9).  Gnus treats subscribed and unsubscribed groups exactly the
-same, but zombie and killed groups have no information on what articles
-you have read, etc, stored.  This distinction between dead and living
-groups isn't done because it is nice or clever, it is done purely for
-reasons of efficiency.
-
-It is recommended that you keep all your mail groups (if any) on quite
-low levels (e.g. 1 or 2).
-
-If you want to play with the level variables, you should show some care.
-Set them once, and don't touch them ever again.  Better yet, don't touch
-them at all unless you know exactly what you're doing.
-
-@vindex gnus-level-default-unsubscribed
-@vindex gnus-level-default-subscribed
-Two closely related variables are @code{gnus-level-default-subscribed}
-(default 3) and @code{gnus-level-default-unsubscribed} (default 6),
-which are the levels that new groups will be put on if they are
-(un)subscribed.  These two variables should, of course, be inside the
-relevant valid ranges.
-
-@vindex gnus-keep-same-level
-If @code{gnus-keep-same-level} is non-@code{nil}, some movement commands
-will only move to groups of the same level (or lower).  In
-particular, going from the last article in one group to the next group
-will go to the next group of the same level (or lower).  This might be
-handy if you want to read the most important groups before you read the
-rest.
-
-@vindex gnus-group-default-list-level
-All groups with a level less than or equal to
-@code{gnus-group-default-list-level} will be listed in the group buffer
-by default.
-
-@vindex gnus-group-list-inactive-groups
-If @code{gnus-group-list-inactive-groups} is non-@code{nil}, non-active
-groups will be listed along with the unread groups.  This variable is

-
-@vindex gnus-group-use-permanent-levels
-If @code{gnus-group-use-permanent-levels} is non-@code{nil}, once you
-give a level prefix to @kbd{g} or @kbd{l}, all subsequent commands will
-use this level as the ``work'' level.
-
-@vindex gnus-activate-level
-Gnus will normally just activate (i. e., query the server about) groups
-on level @code{gnus-activate-level} or less.  If you don't want to

-group buffer according to how often you read groups, perhaps?  Within
-reason?
-
-This is what @dfn{group score} is for.  You can have Gnus assign a score
-to each group through the mechanism described below.  You can then sort
-the group buffer based on this score.  Alternatively, you can sort on
-score and then level.  (Taken together, the level and the score is
-called the @dfn{rank} of the group.  A group that is on level 4 and has
-a score of 1 has a higher rank than a group on level 5 that has a score
-of 300.  (The level is the most significant part and the score is the
-least significant part.))
-
-@findex gnus-summary-bubble-group
-If you want groups you read often to get higher scores than groups you
-read seldom you can add the @code{gnus-summary-bubble-group} function to
-the @code{gnus-summary-exit-hook} hook.  This will result (after
-sorting) in a bubbling sort of action.  If you want to see that in
-action after each summary exit, you can add
-@code{gnus-group-sort-groups-by-rank} or
-@code{gnus-group-sort-groups-by-score} to the same hook, but that will

-
-@node Group Parameters
-@section Group Parameters
-@cindex group parameters
-
-The group parameters store information local to a particular group.
-Here's an example group parameter list:
-
-@example
-((to-address . "ding@@gnus.org")
- (auto-expire . t))
-@end example
-
-We see that each element consists of a "dotted pair"---the thing before
-the dot is the key, while the thing after the dot is the value.  All the
-parameters have this form @emph{except} local variable specs, which are
-not dotted pairs, but proper lists.
-
-The following group parameters can be used:
-
-@table @code
-@item to-address
-@cindex to-address
-Address used by when doing followups and new posts.
-
-@example
-(to-address .  "some@@where.com")
-@end example
-
-This is primarily useful in mail groups that represent closed mailing
-lists---mailing lists where it's expected that everybody that writes to
-the mailing list is subscribed to it.  Since using this parameter
-ensures that the mail only goes to the mailing list itself, it means
-that members won't receive two copies of your followups.
-
-Using @code{to-address} will actually work whether the group is foreign
-or not.  Let's say there's a group on the server that is called
-@samp{fa.4ad-l}.  This is a real newsgroup, but the server has gotten
-the articles from a mail-to-news gateway.  Posting directly to this
-group is therefore impossible---you have to send mail to the mailing
-list address instead.
-
-@item to-list
-@cindex to-list
-Address used when doing a @kbd{a} in that group.
-
-@example
-(to-list . "some@@where.com")
-@end example
-
-It is totally ignored
-when doing a followup---except that if it is present in a news group,
-you'll get mail group semantics when doing @kbd{f}.
-
-If you do an @kbd{a} command in a mail group and you have neither a
-@code{to-list} group parameter nor a @code{to-address} group parameter,
-then a @code{to-list} group parameter will be added automatically upon
-sending the message if @code{gnus-add-to-list} is set to @code{t}.
-@vindex gnus-add-to-list
-
-If you do an @kbd{a} command in a mail group and you don't have a
-@code{to-list} group parameter, one will be added automatically upon
-sending the message.
-
-@item visible
-@cindex visible
-If the group parameter list has the element @code{(visible . t)},
-that group will always be visible in the Group buffer, regardless
-of whether it has any unread articles.
-
-@item broken-reply-to
-@cindex broken-reply-to
-Elements like @code{(broken-reply-to . t)} signals that @code{Reply-To}
-headers in this group are to be ignored.  This can be useful if you're
-reading a mailing list group where the listserv has inserted
-@code{Reply-To} headers that point back to the listserv itself.  This is
-broken behavior.  So there!
-
-@item to-group
-@cindex to-group
-Elements like @code{(to-group . "some.group.name")} means that all
-posts in that group will be sent to @code{some.group.name}.
-
-@item newsgroup
-@cindex newsgroup
-If you have @code{(newsgroup . t)} in the group parameter list, Gnus
-will treat all responses as if they were responses to news articles.
-This can be useful if you have a mail group that's really a mirror of a
-news group.
-
-@item gcc-self
-@cindex gcc-self
-If @code{(gcc-self . t)} is present in the group parameter list, newly
-composed messages will be @code{Gcc}'d to the current group. If
-@code{(gcc-self . none)} is present, no @code{Gcc:} header will be
-generated, if @code{(gcc-self . "string")} is present, this string will
-be inserted literally as a @code{gcc} header.  This parameter takes
-precedence over any default @code{Gcc} rules as described later
-(@pxref{Archived Messages}).
-
-@item auto-expire
-@cindex auto-expire
-If the group parameter has an element that looks like @code{(auto-expire
-. t)}, all articles read will be marked as expirable.  For an
-alternative approach, @pxref{Expiring Mail}.
-
-@item total-expire
-@cindex total-expire
-If the group parameter has an element that looks like
-@code{(total-expire . t)}, all read articles will be put through the
-expiry process, even if they are not marked as expirable.  Use with
-caution.  Unread, ticked and dormant articles are not eligible for
-expiry.
-
-@item expiry-wait
-@cindex expiry-wait
-@vindex nnmail-expiry-wait-function
-If the group parameter has an element that looks like @code{(expiry-wait
-. 10)}, this value will override any @code{nnmail-expiry-wait} and
-@code{nnmail-expiry-wait-function} when expiring expirable messages.
-The value can either be a number of days (not necessarily an integer) or
-the symbols @code{never} or @code{immediate}.
-
-@item score-file
-@cindex score file group parameter
-Elements that look like @code{(score-file . "file")} will make
-@file{file} into the current score file for the group in question.  All
-interactive score entries will be put into this file.
-
-@item adapt-file
-@cindex adapt file group parameter
-Elements that look like @code{(adapt-file . "file")} will make
-@file{file} into the current adaptive file for the group in question.
-All adaptive score entries will be put into this file.
-
-@item admin-address
-When unsubscribing from a mailing list you should never send the
-unsubscription notice to the mailing list itself.  Instead, you'd send
-messages to the administrative address.  This parameter allows you to
-put the admin address somewhere convenient.
-
-@item display
-Elements that look like @code{(display . MODE)} say which articles to
-display on entering the group.  Valid values are:
-
-@table @code
-@item all
-Display all articles, both read and unread.
-
-@item default
-Display the default visible articles, which normally includes unread and
-ticked articles.
-@end table
-
-@item comment
-Elements that look like @code{(comment . "This is a comment")}
-are arbitrary comments on the group.  They are currently ignored by
-Gnus, but provide a place for you to store information on particular
-groups.
-
-@item charset
-Elements that look like @code{(charset . iso-8859-1)} will make
-@code{iso-8859-1} the default charset; that is, the charset that will be
-used for all articles that do not specify a charset.
-
-@item (@var{variable} @var{form})
-You can use the group parameters to set variables local to the group you
-are entering.  If you want to turn threading off in @samp{news.answers},
-you could put @code{(gnus-show-threads nil)} in the group parameters of
-that group.  @code{gnus-show-threads} will be made into a local variable
-in the summary buffer you enter, and the form @code{nil} will be
-@code{eval}ed there.
-
-This can also be used as a group-specific hook function, if you'd like.
-If you want to hear a beep when you enter a group, you could put
-something like @code{(dummy-variable (ding))} in the parameters of that
-group.  @code{dummy-variable} will be set to the result of the
-@code{(ding)} form, but who cares?
-
-@item posting-style
-You can store additional posting style information for this group only
-here (@pxref{Posting Styles}). The format is that of an entry in the

-@kindex A k (Group)
-@findex gnus-group-list-killed
-List all killed groups (@code{gnus-group-list-killed}).  If given a

-This is in fact how the variable @code{gnus-topic-topology} would look
-for the display above.  That variable is saved in the @file{.newsrc.eld}
-file, and shouldn't be messed with manually---unless you really want
-to.  Since this variable is read from the @file{.newsrc.eld} file,
-setting it in any other startup files will have no effect.
-
-This topology shows what topics are sub-topics of what topics (right),
-and which topics are visible.  Two settings are currently
-allowed---@code{visible} and @code{invisible}.
-
-
-@node Topic Parameters
-@subsection Topic Parameters
-@cindex topic parameters
-
-All groups in a topic will inherit group parameters from the parent (and
-ancestor) topic parameters.  All valid group parameters are valid topic
-parameters (@pxref{Group Parameters}).
-
-Group parameters (of course) override topic parameters, and topic
-parameters in sub-topics override topic parameters in super-topics.  You
-know.  Normal inheritance rules.  (@dfn{Rules} is here a noun, not a
-verb, although you may feel free to disagree with me here.)
-
-@example
-Gnus
-  Emacs
-     3: comp.emacs
-     2: alt.religion.emacs
-   452: alt.sex.emacs
-    Relief
-     452: alt.sex.emacs
-       0: comp.talk.emacs.recovery
-  Misc
-     8: comp.binaries.fractals
-    13: comp.sources.unix
-   452: alt.sex.emacs
-@end example
-
-The @samp{Emacs} topic has the topic parameter @code{(score-file
-. "emacs.SCORE")}; the @samp{Relief} topic has the topic parameter
-@code{(score-file . "relief.SCORE")}; and the @samp{Misc} topic has the
-topic parameter @code{(score-file . "emacs.SCORE")}.  In addition,
-@* @samp{alt.religion.emacs} has the group parameter @code{(score-file
-. "religion.SCORE")}.
-
-Now, when you enter @samp{alt.sex.emacs} in the @samp{Relief} topic, you
-will get the @file{relief.SCORE} home score file.  If you enter the same
-group in the @samp{Emacs} topic, you'll get the @file{emacs.SCORE} home
-score file.  If you enter the group @samp{alt.religion.emacs}, you'll
-get the @file{religion.SCORE} home score file.
-
-This seems rather simple and self-evident, doesn't it?  Well, yes.  But
-there are some problems, especially with the @code{total-expiry}
-parameter.  Say you have a mail group in two topics; one with
-@code{total-expiry} and one without.  What happens when you do @kbd{M-x
-gnus-expire-all-expirable-groups}?  Gnus has no way of telling which one
-of these topics you mean to expire articles from, so anything may
-happen.  In fact, I hereby declare that it is @dfn{undefined} what
-happens.  You just have to be careful if you do stuff like that.

-
-The following format specification characters are understood:
-
-@table @samp
-@item N
-Article number.
-@item S
-Subject string. List identifiers stripped, @code{gnus-list-identifies}. @xref{Article Hiding}.
-@item s
-Subject if the article is the root of the thread or the previous article
-had a different subject, @code{gnus-summary-same-subject} otherwise.
-(@code{gnus-summary-same-subject} defaults to @code{""}.)
-@item F

-@item n
-The name (from the @code{From} header).
-@item f
-The name, code @code{To} header or the @code{Newsgroups} header
-(@pxref{To From Newsgroups}).
-@item a
-The name (from the @code{From} header).  This differs from the @code{n}
-spec in that it uses the function designated by the
-@code{gnus-extract-address-components} variable, which is slower, but
-may be more thorough.
-@item A

-
-The @samp{%U} (status), @samp{%R} (replied) and @samp{%z} (zcore) specs
-have to be handled with care.  For reasons of efficiency, Gnus will
-compute what column these characters will end up in, and ``hard-code''
-that.  This means that it is invalid to have these specs after a

-buffer will look strange, which is bad enough.

-@cindex To
-@cindex Newsgroups
-
-In some groups (particularly in archive groups), the @code{From} header
-isn't very interesting, since all the articles there are written by
-you.  To display the information in the @code{To} or @code{Newsgroups}
-headers instead, you need to decide three things: What information to
-gather; where to display it; and when to display it.
-
-@enumerate
-@item
-@vindex gnus-extra-headers
-The reading of extra header information is controlled by the
-@code{gnus-extra-headers}.  This is a list of header symbols.  For
-instance:
-
-@lisp
-(setq gnus-extra-headers
-      '(To Newsgroups X-Newsreader))
-@end lisp
-
-This will result in Gnus trying to obtain these three headers, and
-storing it in header structures for later easy retrieval.
-
-@item
-@findex gnus-extra-header
-The value of these extra headers can be accessed via the
-@code{gnus-extra-header} function.  Here's a format line spec that will
-access the @code{X-Newsreader} header:
-
-@example
-"%~(form (gnus-extra-header 'X-Newsreader))@@"
-@end example
-
-@item
-@vindex gnus-ignored-from-addresses
-The @code{gnus-ignored-from-addresses} variable says when the @samp{%f}
-summary line spec returns the @code{To}, @code{Newsreader} or
-@code{From} header.  If this regexp matches the contents of the
-@code{From} header, the value of the @code{To} or @code{Newsreader}
-headers are used instead.
-
-@end enumerate
-
-@vindex nnmail-extra-headers
-A related variable is @code{nnmail-extra-headers}, which controls when
-to include extra headers when generating overview (@sc{nov}) files.  If
-you have old overview files, you should regenerate them after changing
-this variable.
-
-@vindex gnus-summary-line-format
-You also have to instruct Gnus to display the data by changing the
-@code{%n} spec to the @code{%f} spec in the
-@code{gnus-summary-line-format} variable.
-
-In summary, you'd typically do something like the following:
-
-@lisp
-(setq gnus-extra-headers
-      '(To Newsgroups))
-(setq nnmail-extra-headers gnus-extra-headers)
-(setq gnus-summary-line-format
-      "%U%R%z%I%(%[%4L: %-20,20f%]%) %s\n")
-(setq gnus-ignored-from-addresses
-      "Your Name Here")
-@end lisp
-
-Now, this is mostly useful for mail groups, where you have control over
-the @sc{nov} files that are created.  However, if you can persuade your
-nntp admin to add:
-
-@example
-Newsgroups:full
-@end example
-
-to the end of her @file{overview.fmt} file, then you can use that just
-as you would the extra headers from the mail groups.

-@end table
-
-If Gnus asks you to press a key to confirm going to the next group, you
-can use the @kbd{C-n} and @kbd{C-p} keys to move around the group
-buffer, searching for the next group to read without actually returning
-to the group buffer.
-
-Variables related to summary movement:
-
-@table @code
-
-@vindex gnus-auto-select-next
-@item gnus-auto-select-next
-If you issue one of the movement commands (like @kbd{n}) and there are
-no more unread articles after the current one, Gnus will offer to go to
-the next group.  If this variable is @code{t} and the next group is
-empty, Gnus will exit summary mode and return to the group buffer.  If
-this variable is neither @code{t} nor @code{nil}, Gnus will select the
-next group, no matter whether it has any unread articles or not.  As a
-special case, if this variable is @code{quietly}, Gnus will select the
-next group without asking for confirmation.  If this variable is
-@code{almost-quietly}, the same will happen only if you are located on
-the last article in the group.  Finally, if this variable is
-@code{slightly-quietly}, the @kbd{Z n} command will go to the next group
-without confirmation.  Also @pxref{Group Levels}.
-
-@item gnus-auto-select-same
-@vindex gnus-auto-select-same
-If non-@code{nil}, all the movement commands will try to go to the next
-article with the same subject as the current.  (@dfn{Same} here might
-mean @dfn{roughly equal}.  See @code{gnus-summary-gather-subject-limit}
-for details (@pxref{Customizing Threading}).)  If there are no more
-articles with the same subject, go to the first unread article.
-
-This variable is not particularly useful if you use a threaded display.
-
-@item gnus-summary-check-current
-@vindex gnus-summary-check-current
-If non-@code{nil}, all the ``unread'' movement commands will not proceed
-to the next (or previous) article if the current article is unread.
-Instead, they will choose the current article.
-
-@item gnus-auto-center-summary
-@vindex gnus-auto-center-summary
-If non-@code{nil}, Gnus will keep the point in the summary buffer
-centered at all times.  This makes things quite tidy, but if you have a
-slow network connection, or simply do not like this un-Emacsism, you can
-set this variable to @code{nil} to get the normal Emacs scrolling
-action.  This will also inhibit horizontal re-centering of the summary
-buffer, which might make it more inconvenient to read extremely long
-threads.
-
-This variable can also be a number.  In that case, center the window at
-the given number of lines from the top.

-If you have sent a mail, but the mail was bounced back to you for some
-reason (wrong address, transient failure), you can use this command to
-resend that bounced mail (@code{gnus-summary-resend-bounced-mail}).  You
-will be popped into a mail buffer where you can edit the headers before
-sending the mail off again.  If you give a prefix to this command, and

-that mail and display it for easy perusal of its headers.  This might
-very well fail, though.
-
-@item S D r
-@kindex S D r (Summary)
-@findex gnus-summary-resend-message
-Not to be confused with the previous command,
-@code{gnus-summary-resend-message} will prompt you for an address to
-send the current message off to, and then send it to that place.  The
-headers of the message won't be altered---but lots of headers that say
-@code{Resent-To}, @code{Resent-From} and so on will be added.  This
-means that you actually send a mail to someone that has a @code{To}
-header that (probably) points to yourself.  This will confuse people.
-So, natcherly you'll only do that if you're really eVIl.
-
-This command is mainly used if you have several accounts and want to
-ship a mail to a different account of yours.  (If you're both
-@code{root} and @code{postmaster} and get a mail for @code{postmaster}
-to the @code{root} account, you may want to resend it to

-Find the article you wish to cancel (you can only cancel your own

-c} (@code{gnus-summary-cancel-article}).  Your article will be
-canceled---machines all over the world will be deleting your article.
-This command uses the process/prefix convention (@pxref{Process/Prefix}).
-
-Be aware, however, that not all sites honor cancels, so your article may
-live on here and there, while most sites will delete the article in
-question.
-
-Gnus will use the ``current'' select method when canceling.  If you
-want to use the standard posting method, use the @samp{a} symbolic
-prefix (@pxref{Symbolic Prefixes}).
-
-If you discover that you have made some mistakes and want to do some
-corrections, you can post a @dfn{superseding} article that will replace
-your original article.
-
-@findex gnus-summary-supersede-article
-@kindex S (Summary)

-(@code{gnus-summary-supersede-article}).  You will be put in a buffer
-where you can edit the article all you want before sending it off the
-usual way.
-
-The same goes for superseding as for canceling, only more so: Some
-sites do not honor superseding.  On those sites, it will appear that you
-have posted almost the same article twice.
-
-If you have just posted the article, and change your mind right away,
-there is a trick you can use to cancel/supersede the article without
-waiting for the article to appear on your site first.  You simply return
-to the post buffer (which is called @code{*sent ...*}).  There you will
-find the article you just posted, with all the headers intact.  Change
-the @code{Message-ID} header to a @code{Cancel} or @code{Supersedes}
-header by substituting one of those words for the word
-@code{Message-ID}.  Then just press @kbd{C-c C-c} to send the article as
-you would do normally.  The previous article will be
-canceled/superseded.

-
-@itemize @bullet
-
-@item
-You can set a bookmark in the current article.  Say you are reading a
-long thesis on cats' urinary tracts, and have to go home for dinner
-before you've finished reading the thesis.  You can then set a bookmark
-in the article, and Gnus will jump to this bookmark the next time it
-encounters the article.  @xref{Setting Marks}.

-All articles that you have replied to or made a followup to (i.e., have
-answered) will be marked with an @samp{A} in the second column
-(@code{gnus-replied-mark}).
-
-@item

-Articles stored in the article cache will be marked with an @samp{*} in
-the second column (@code{gnus-cached-mark}).  @xref{Article Caching}.
-
-@item
-@vindex gnus-saved-mark
-Articles ``saved'' (in some manner or other; not necessarily
-religiously) are marked with an @samp{S} in the second column
-(@code{gnus-saved-mark}).
-
-@item
-@vindex gnus-not-empty-thread-mark
-@vindex gnus-empty-thread-mark
-If the @samp{%e} spec is used, the presence of threads or not will be
-marked with @code{gnus-not-empty-thread-mark} and
-@code{gnus-empty-thread-mark} in the third column, respectively.
-
-@item
-@vindex gnus-process-mark
-Finally we have the @dfn{process mark} (@code{gnus-process-mark}).  A
-variety of commands react to the presence of the process mark.  For
-instance, @kbd{X u} (@code{gnus-uu-decode-uu}) will uudecode and view
-all articles that have been marked with the process mark.  Articles
-marked with the process mark have a @samp{#} in the second column.
-
-@end itemize
-
-You might have noticed that most of these ``non-readedness'' marks
-appear in the second column by default.  So if you have a cached, saved,
-replied article that you have process-marked, what will that look like?
-
-Nothing much.  The precedence rules go as follows: process -> cache ->
-replied -> saved.  So if the article is in the cache and is replied,
-you'll only see the cache mark and not the replied mark.

-@node Generic Marking Commands
-@subsection Generic Marking Commands
-
-Some people would like the command that ticks an article (@kbd{!}) go to
-the next article.  Others would like it to go to the next unread
-article.  Yet others would like it to stay on the current article.  And
-even though I haven't heard of anybody wanting it to go to the
-previous (unread) article, I'm sure there are people that want that as
-well.
-
-Multiply these five behaviours with five different marking commands, and
-you get a potentially complex set of variable to control what each
-command should do.
-
-To sidestep that mess, Gnus provides commands that do all these
-different things.  They can be found on the @kbd{M M} map in the summary
-buffer.  Type @kbd{M M C-h} to see them all---there are too many of them
-to list in this manual.
-
-While you can use these commands directly, most users would prefer
-altering the summary mode keymap.  For instance, if you would like the
-@kbd{!} command to go to the next article instead of the next unread
-article, you could say something like:
-
-@lisp
-(add-hook 'gnus-summary-mode-hook 'my-alter-summary-map)
-(defun my-alter-summary-map ()
-  (local-set-key "!" 'gnus-summary-put-mark-as-ticked-next))

-@cindex threading
-@cindex article threading
-
-Gnus threads articles by default.  @dfn{To thread} is to put responses
-to articles directly after the articles they respond to---in a
-hierarchical fashion.
-
-Threading is done by looking at the @code{References} headers of the
-articles.  In a perfect world, this would be enough to build pretty
-trees, but unfortunately, the @code{References} header is often broken
-or simply missing.  Weird news propagation excarcerbates the problem,
-so one has to employ other heuristics to get pleasing results.  A
-plethora of approaches exists, as detailed in horrible detail in
-@pxref{Customizing Threading}.
-
-First, a quick overview of the concepts:
-
-@table @dfn
-@item root
-The top-most article in a thread; the first article in the thread.
-
-@item thread
-A tree-like article structure.
-
-@item sub-thread
-A small(er) section of this tree-like structure.
-
-@item loose threads
-Threads often lose their roots due to article expiry, or due to the root
-already having been read in a previous session, and not displayed in the
-summary buffer.  We then typically have many sub-threads that really
-belong to one thread, but are without connecting roots.  These are
-called loose threads.
-
-@item thread gathering
-An attempt to gather loose threads into bigger threads.
-
-@item sparse threads
-A thread where the missing articles have been ``guessed'' at, and are
-displayed as empty lines in the summary buffer.

-@table @code
-@item gnus-summary-make-false-root
-@vindex gnus-summary-make-false-root
-If non-@code{nil}, Gnus will gather all loose subtrees into one big tree
-and create a dummy root at the top.  (Wait a minute.  Root at the top?
-Yup.)  Loose subtrees occur when the real root has expired, or you've
-read or killed the root in a previous session.
-
-When there is no real root of a thread, Gnus will have to fudge
-something.  This variable says what fudging method Gnus should use.
-There are four possible values:
-
-@iftex
-@end iftex
-
-@cindex adopting articles
-
-@table @code
-
-@item adopt
-Gnus will make the first of the orphaned articles the parent.  This
-parent will adopt all the other articles.  The adopted articles will be
-marked as such by pointy brackets (@samp{<>}) instead of the standard
-square brackets (@samp{[]}).  This is the default method.
-
-@item dummy
-@vindex gnus-summary-dummy-line-format
-Gnus will create a dummy summary line that will pretend to be the
-parent.  This dummy line does not correspond to any real article, so
-selecting it will just select the first real article after the dummy
-article.  @code{gnus-summary-dummy-line-format} is used to specify the
-format of the dummy roots.  It accepts only one format spec:  @samp{S},
-which is the subject of the article.  @xref{Formatting Variables}.
-
-@item empty
-Gnus won't actually make any article the parent, but simply leave the
-subject field of all orphans except the first empty.  (Actually, it will
-use @code{gnus-summary-same-subject} as the subject (@pxref{Summary
-Buffer Format}).)
-
-@item none
-Don't make any article parent at all.  Just gather the threads and
-display them after one another.
-
-@item nil
-Don't gather loose threads.
-@end table
-
-@item gnus-summary-gather-subject-limit
-@vindex gnus-summary-gather-subject-limit
-Loose threads are gathered by comparing subjects of articles.  If this
-variable is @code{nil}, Gnus requires an exact match between the
-subjects of the loose threads before gathering them into one big
-super-thread.  This might be too strict a requirement, what with the
-presence of stupid newsreaders that chop off long subject lines.  If
-you think so, set this variable to, say, 20 to require that only the
-first 20 characters of the subjects have to match.  If you set this
-variable to a really low number, you'll find that Gnus will gather
-everything in sight into one thread, which isn't very helpful.
-
-@cindex fuzzy article gathering
-If you set this variable to the special value @code{fuzzy}, Gnus will
-use a fuzzy string comparison algorithm on the subjects (@pxref{Fuzzy
-Matching}).

-arrive at the simplified version of the string.
-
-Useful functions to put in this list include:
-
-@table @code
-@item gnus-simplify-subject-re
-@findex gnus-simplify-subject-re

-@end table
-
-You may also write your own functions, of course.
-
-
-@item gnus-summary-gather-exclude-subject
-@vindex gnus-summary-gather-exclude-subject
-Since loose thread gathering is done on subjects only, that might lead
-to many false hits, especially with certain common subjects like
-@samp{} and @samp{(none)}.  To make the situation slightly better,
-you can use the regexp @code{gnus-summary-gather-exclude-subject} to say
-what subjects should be excluded from the gathering process.@*
-The default is @samp{^ *$\\|^(none)$}.
-
-@item gnus-summary-thread-gathering-function
-@vindex gnus-summary-thread-gathering-function

-is confusing.  An alternate approach is to look at all the

-This will ensure that no gathered threads ever include unrelated
-articles, but it also means that people who have posted with broken
-newsreaders won't be gathered properly.  The choice is yours---plague or

-@item gnus-fetch-old-headers

-If non-@code{nil}, Gnus will attempt to build old threads by fetching
-more old headers---headers to articles marked as read.  If you
-would like to display as few summary lines as possible, but still
-connect as many loose threads as possible, you should set this variable
-to @code{some} or a number.  If you set it to a number, no more than
-that number of extra old headers will be fetched.  In either case,
-fetching old headers only works if the backend you are using carries
-overview files---this would normally be @code{nntp}, @code{nnspool} and
-@code{nnml}.  Also remember that if the root of the thread has been
-expired by the server, there's not much Gnus can do about that.

-the complete @code{References} headers of all articles and try to string
-together articles that belong in the same thread.  This will leave
-@dfn{gaps} in the threading display where Gnus guesses that an article
-is missing from the thread.  (These gaps appear like normal summary
-lines.  If you select a gap, Gnus will try to fetch the article in
-question.)  If this variable is @code{t}, Gnus will display all these
-``gaps'' without regard for whether they are useful for completing the
-thread or not.  Finally, if this variable is @code{more}, Gnus won't cut
-off sparse leaf nodes that don't lead anywhere.  This variable is

-If you are using a threaded summary display, you can sort the threads by
-setting @code{gnus-thread-sort-functions}, which can be either a single
-function, a list of functions, or a list containing functions and
-@code{(not some-function)} elements.
-
-By default, sorting is done on article numbers.  Ready-made sorting
-predicate functions include @code{gnus-thread-sort-by-number},
-@code{gnus-thread-sort-by-author}, @code{gnus-thread-sort-by-subject},
-@code{gnus-thread-sort-by-date}, @code{gnus-thread-sort-by-score}, and
-@code{gnus-thread-sort-by-total-score}.
-
-Each function takes two threads and returns non-@code{nil} if the first
-thread should be sorted before the other.  Note that sorting really is
-normally done by looking only at the roots of each thread.
-
-If you use more than one function, the primary sort key should be the
-last function in the list.  You should probably always include
-@code{gnus-thread-sort-by-number} in the list of sorting
-functions---preferably first.  This will ensure that threads that are
-equal with respect to the other sort criteria will be displayed in
-ascending article order.
-
-If you would like to sort by reverse score, then by subject, and finally
-by number, you could do something like:
-
-@lisp
-(setq gnus-thread-sort-functions
-      '(gnus-thread-sort-by-number
-        gnus-thread-sort-by-subject
-        (not gnus-thread-sort-by-total-score)))
-@end lisp
-
-The threads that have highest score will be displayed first in the
-summary buffer.  When threads have the same score, they will be sorted
-alphabetically.  The threads that have the same score and the same
-subject will be sorted by number, which is (normally) the sequence in
-which the articles arrived.
-
-If you want to sort by score and then reverse arrival order, you could
-say something like:
-
-@lisp
-(setq gnus-thread-sort-functions
-      '((lambda (t1 t2)

-@end lisp
-
-@vindex gnus-thread-score-function
-The function in the @code{gnus-thread-score-function} variable (default

-@node Asynchronous Fetching
-@section Asynchronous Article Fetching
-@cindex asynchronous article fetching
-@cindex article pre-fetch
-@cindex pre-fetch
-
-If you read your news from an @sc{nntp} server that's far away, the
-network latencies may make reading articles a chore.  You have to wait
-for a while after pressing @kbd{n} to go to the next article before the
-article appears.  Why can't Gnus just go ahead and fetch the article
-while you are reading the previous one?  Why not, indeed.
-
-First, some caveats.  There are some pitfalls to using asynchronous
-article fetching, especially the way Gnus does it.
-
-Let's say you are reading article 1, which is short, and article 2 is
-quite long, and you are not interested in reading that.  Gnus does not
-know this, so it goes ahead and fetches article 2.  You decide to read
-article 3, but since Gnus is in the process of fetching article 2, the
-connection is blocked.
-
-To avoid these situations, Gnus will open two (count 'em two)
-connections to the server.  Some people may think this isn't a very nice
-thing to do, but I don't see any real alternatives.  Setting up that
-extra connection takes some time, so Gnus startup will be slower.
-
-Gnus will fetch more articles than you will read.  This will mean that
-the link between your machine and the @sc{nntp} server will become more
-loaded than if you didn't use article pre-fetch.  The server itself will
-also become more loaded---both with the extra article requests, and the
-extra connection.
-
-Ok, so now you know that you shouldn't really use this thing...  unless
-you really want to.
-
-@vindex gnus-asynchronous
-Here's how:  Set @code{gnus-asynchronous} to @code{t}.  The rest should
-happen automatically.
-
-@vindex gnus-use-article-prefetch
-You can control how many articles are to be pre-fetched by setting
-@code{gnus-use-article-prefetch}.  This is 30 by default, which means
-that when you read an article in the group, the backend will pre-fetch
-the next 30 articles.  If this variable is @code{t}, the backend will
-pre-fetch all the articles it can without bound.  If it is
-@code{nil}, no pre-fetching will be done.
-
-@vindex gnus-async-prefetch-article-p
-@findex gnus-async-read-p
-There are probably some articles that you don't want to pre-fetch---read
-articles, for instance.  The @code{gnus-async-prefetch-article-p} variable controls whether an article is to be pre-fetched.  This function should
-return non-@code{nil} when the article in question is to be
-pre-fetched.  The default is @code{gnus-async-read-p}, which returns
-@code{nil} on read articles.  The function is called with an article
-data structure as the only parameter.
-
-If, for instance, you wish to pre-fetch only unread articles shorter than 100 lines, you could say something like:
-
-@lisp
-(defun my-async-short-unread-p (data)
-  "Return non-nil for short, unread articles."
-  (and (gnus-data-unread-p data)
-       (< (mail-header-lines (gnus-data-header data))
-          100)))
-
-(setq gnus-async-prefetch-article-p 'my-async-short-unread-p)
-@end lisp
-
-These functions will be called many, many times, so they should
-preferably be short and sweet to avoid slowing down Gnus too much.
-It's probably a good idea to byte-compile things like this.
-
-@vindex gnus-prefetched-article-deletion-strategy
-Articles have to be removed from the asynch buffer sooner or later.  The
-@code{gnus-prefetched-article-deletion-strategy} says when to remove
-articles.  This is a list that may contain the following elements:
-
-@table @code
-@item read

-@cindex caching
-
-If you have an @emph{extremely} slow @sc{nntp} connection, you may
-consider turning article caching on.  Each article will then be stored
-locally under your home directory.  As you may surmise, this could
-potentially use @emph{huge} amounts of disk space, as well as eat up all
-your inodes so fast it will make your head swim.  In vodka.
-
-Used carefully, though, it could be just an easier way to save articles.
-
-@vindex gnus-use-long-file-name
-@vindex gnus-cache-directory
-@vindex gnus-use-cache
-To turn caching on, set @code{gnus-use-cache} to @code{t}.  By default,
-all articles ticked or marked as dormant will then be copied
-over to your local cache (@code{gnus-cache-directory}).  Whether this
-cache is flat or hierarchal is controlled by the
-@code{gnus-use-long-file-name} variable, as usual.
-
-When re-selecting a ticked or dormant article, it will be fetched from the
-cache instead of from the server.  As articles in your cache will never
-expire, this might serve as a method of saving articles while still
-keeping them where they belong.  Just mark all articles you want to save
-as dormant, and don't worry.
-
-When an article is marked as read, is it removed from the cache.
-
-@vindex gnus-cache-remove-articles
-@vindex gnus-cache-enter-articles
-The entering/removal of articles from the cache is controlled by the
-@code{gnus-cache-enter-articles} and @code{gnus-cache-remove-articles}
-variables.  Both are lists of symbols.  The first is @code{(ticked
-dormant)} by default, meaning that ticked and dormant articles will be
-put in the cache.  The latter is @code{(read)} by default, meaning that
-articles marked as read are removed from the cache.  Possibly
-symbols in these two lists are @code{ticked}, @code{dormant},
-@code{unread} and @code{read}.
-
-@findex gnus-jog-cache
-So where does the massive article-fetching and storing come into the
-picture?  The @code{gnus-jog-cache} command will go through all
-subscribed newsgroups, request all unread articles, score them, and
-store them in the cache.  You should only ever, ever ever ever, use this
-command if 1) your connection to the @sc{nntp} server is really, really,
-really slow and 2) you have a really, really, really huge disk.
-Seriously.  One way to cut down on the number of articles downloaded is
-to score unwanted articles down and have them marked as read.  They will
-not then be downloaded by this command.
-
-@vindex gnus-uncacheable-groups
-@vindex gnus-cacheable-groups
-It is likely that you do not want caching on all groups.  For instance,
-if your @code{nnml} mail is located under your home directory, it makes no
-sense to cache it somewhere else under your home directory.  Unless you
-feel that it's neat to use twice as much space.
-
-To limit the caching, you could set @code{gnus-cacheable-groups} to a
-regexp of groups to cache, @samp{^nntp} for instance, or set the
-@code{gnus-uncacheable-groups} regexp to @samp{^nnml}, for instance.
-Both variables are @code{nil} by default. If a group matches both
-variables, the group is not cached.
-
-@findex gnus-cache-generate-nov-databases
-@findex gnus-cache-generate-active
-@vindex gnus-cache-active-file
-The cache stores information on what articles it contains in its active
-file (@code{gnus-cache-active-file}).  If this file (or any other parts
-of the cache) becomes all messed up for some reason or other, Gnus
-offers two functions that will try to set things right.  @kbd{M-x

-@node Persistent Articles
-@section Persistent Articles
-@cindex persistent articles
-
-Closely related to article caching, we have @dfn{persistent articles}.
-In fact, it's just a different way of looking at caching, and much more
-useful in my opinion.
-
-Say you're reading a newsgroup, and you happen on to some valuable gem
-that you want to keep and treasure forever.  You'd normally just save it
-(using one of the many saving commands) in some file.  The problem with
-that is that it's just, well, yucky.  Ideally you'd prefer just having
-the article remain in the group where you found it forever; untouched by
-the expiry going on at the news server.
-
-This is what a @dfn{persistent article} is---an article that just won't
-be deleted.  It's implemented using the normal cache functions, but
-you use two explicit commands for managing persistent articles:
-
-@table @kbd
-
-@item *
-@kindex * (Summary)
-@findex gnus-cache-enter-article
-Make the current article persistent (@code{gnus-cache-enter-article}).
-
-@item M-*
-@kindex M-* (Summary)
-@findex gnus-cache-remove-article
-Remove the current article from the persistent articles
-(@code{gnus-cache-remove-article}).  This will normally delete the
-article.
-@end table
-
-Both these commands understand the process/prefix convention.
-
-To avoid having all ticked articles (and stuff) entered into the cache,
-you should set @code{gnus-use-cache} to @code{passive} if you're just
-interested in persistent articles:
-
-@lisp
-(setq gnus-use-cache 'passive)
-@end lisp
-
-
-@node Article Backlog
-@section Article Backlog
-@cindex backlog
-@cindex article backlog
-
-If you have a slow connection, but the idea of using caching seems
-unappealing to you (and it is, really), you can help the situation some
-by switching on the @dfn{backlog}.  This is where Gnus will buffer
-already read articles so that it doesn't have to re-fetch articles
-you've already read.  This only helps if you are in the habit of
-re-selecting articles you've recently read, of course.  If you never do
-that, turning the backlog on will slow Gnus down a little bit, and
-increase memory usage some.
-
-@vindex gnus-keep-backlog
-If you set @code{gnus-keep-backlog} to a number @var{n}, Gnus will store
-at most @var{n} old articles in a buffer for later re-fetching.  If this
-variable is non-@code{nil} and is not a number, Gnus will store
-@emph{all} read articles, which means that your Emacs will grow without

-loathe.  If you set this variable to @code{t} instead, you'll be prompted
-just once for each series of articles you save.  If you like to really
-have Gnus do all your thinking for you, you can even set this variable
-to @code{nil}, which means that you will never be prompted for files to

-
-
-@vindex gnus-default-article-saver
-You can customize the @code{gnus-default-article-saver} variable to make

-
-@item gnus-summary-save-in-rmail
-@findex gnus-summary-save-in-rmail
-@vindex gnus-rmail-save-name
-@findex gnus-plain-save-name
-This is the default format, @dfn{babyl}.  Uses the function in the
-@code{gnus-rmail-save-name} variable to get a file name to save the
-article in.  The default is @code{gnus-plain-save-name}.
-
-@item gnus-summary-save-in-mail
-@findex gnus-summary-save-in-mail
-@vindex gnus-mail-save-name
-Save in a Unix mail (mbox) file.  Uses the function in the

-
-@item gnus-summary-save-in-file
-@findex gnus-summary-save-in-file
-@vindex gnus-file-save-name
-@findex gnus-numeric-save-name
-Append the article straight to an ordinary file.  Uses the function in

-article in.  The default is @code{gnus-numeric-save-name}.
-
-@item gnus-summary-save-body-in-file
-@findex gnus-summary-save-body-in-file
-Append the article body to an ordinary file.  Uses the function in the
-@code{gnus-file-save-name} variable to get a file name to save the
-article in.  The default is @code{gnus-numeric-save-name}.
-
-@item gnus-summary-save-in-folder
-@findex gnus-summary-save-in-folder
-@findex gnus-folder-save-name
-@findex gnus-Folder-save-name
-@vindex gnus-folder-save-name
-@cindex rcvstore
-@cindex MH folders
-Save the article to an MH folder using @code{rcvstore} from the MH
-library.  Uses the function in the @code{gnus-folder-save-name} variable
-to get a file name to save the article in.  The default is
-@code{gnus-folder-save-name}, but you can also use
-@code{gnus-Folder-save-name}, which creates capitalized names.
-
-@item gnus-summary-save-in-vm
-@findex gnus-summary-save-in-vm
-Save the article in a VM folder.  You have to have the VM mail
-reader to use this setting.
-@end table
-
-@vindex gnus-article-save-directory
-All of these functions, except for the last one, will save the article
-in the @code{gnus-article-save-directory}, which is initialized from the
-@code{SAVEDIR} environment variable.  This is @file{~/News/} by
-default.
-
-As you can see above, the functions use different functions to find a
-suitable name of a file to save the article in.  Below is a list of
-available functions that generate names:
-
-@table @code
-
-@item gnus-Numeric-save-name
-@findex gnus-Numeric-save-name
-File names like @file{~/News/Alt.andrea-dworkin/45}.
-
-@item gnus-numeric-save-name
-@findex gnus-numeric-save-name
-File names like @file{~/News/alt.andrea-dworkin/45}.
-
-@item gnus-Plain-save-name
-@findex gnus-Plain-save-name
-File names like @file{~/News/Alt.andrea-dworkin}.
-
-@item gnus-plain-save-name
-@findex gnus-plain-save-name
-File names like @file{~/News/alt.andrea-dworkin}.
-@end table
-
-@vindex gnus-split-methods
-You can have Gnus suggest where to save articles by plonking a regexp into
-the @code{gnus-split-methods} alist.  For instance, if you would like to
-save articles related to Gnus in the file @file{gnus-stuff}, and articles
-related to VM in @code{vm-stuff}, you could set this variable to something
-like:
-
-@lisp
-(("^Subject:.*gnus\\|^Newsgroups:.*gnus" "gnus-stuff")
- ("^Subject:.*vm\\|^Xref:.*vm" "vm-stuff")
- (my-choosing-function "../other-dir/my-stuff")
- ((equal gnus-newsgroup-name "mail.misc") "mail-stuff"))
-@end lisp
-
-We see that this is a list where each element is a list that has two
-elements---the @dfn{match} and the @dfn{file}.  The match can either be
-a string (in which case it is used as a regexp to match on the article
-head); it can be a symbol (which will be called as a function with the
-group name as a parameter); or it can be a list (which will be
-@code{eval}ed).  If any of these actions have a non-@code{nil} result,
-the @dfn{file} will be used as a default prompt.  In addition, the
-result of the operation itself will be used if the function or form
-called returns a string or a list of strings.
-
-You basically end up with a list of file names that might be used when
-saving the current article.  (All ``matches'' will be used.)  You will
-then be prompted for what you really want to use as a name, with file
-name completion over the results from applying this variable.
-
-This variable is @code{((gnus-article-archive-name))} by default, which
-means that Gnus will look at the articles it saves for an
-@code{Archive-name} line and use that as a suggestion for the file
-name.
-
-Here's an example function to clean up file names somewhat.  If you have
-lots of mail groups called things like
-@samp{nnml:mail.whatever}, you may want to chop off the beginning of
-these group names before creating the file name to save to.  The
-following will do just that:
-
-@lisp
-(defun my-save-name (group)
-  (when (string-match "^nnml:mail." group)
-    (substring group (match-end 0))))
-
-(setq gnus-split-methods
-      '((gnus-article-archive-name)
-        (my-save-name)))
-@end lisp
-
-
-@vindex gnus-use-long-file-name
-Finally, you have the @code{gnus-use-long-file-name} variable.  If it is
-@code{nil}, all the preceding functions will replace all periods
-(@samp{.}) in the group names with slashes (@samp{/})---which means that
-the functions will generate hierarchies of directories instead of having
-all the files in the top level directory
-(@file{~/News/alt/andrea-dworkin} instead of
-@file{~/News/alt.andrea-dworkin}.)  This variable is @code{t} by default
-on most systems.  However, for historical reasons, this is @code{nil} on
-Xenix and usg-unix-v machines by default.
-
-This function also affects kill and score file names.  If this variable
-is a list, and the list contains the element @code{not-score}, long file
-names will not be used for score files, if it contains the element
-@code{not-save}, long file names will not be used for saving, and if it
-contains the element @code{not-kill}, long file names will not be used
-for kill files.
-
-If you'd like to save articles in a hierarchy that looks something like
-a spool, you could
-
-@lisp
-(setq gnus-use-long-file-name '(not-save)) ; to get a hierarchy
-(setq gnus-default-article-saver 'gnus-summary-save-in-file) ; no encoding
-@end lisp
-
-Then just save with @kbd{o}.  You'd then read this hierarchy with
-ephemeral @code{nneething} groups---@kbd{G D} in the group buffer, and
-the top level directory as the argument (@file{~/News/}).  Then just walk
-around to the groups/directories with @code{nneething}.

-@cindex series
-@cindex article series
-All these functions use the process/prefix convention
-(@pxref{Process/Prefix}) for finding out what articles to work on, with
-the extension that a ``single article'' means ``a single series''.  Gnus
-can find out by itself what articles belong to a series, decode all the
-articles and unpack/view/save the resulting file(s).
-
-Gnus guesses what articles are in the series according to the following
-simplish rule: The subjects must be (nearly) identical, except for the
-last two numbers of the line.  (Spaces are largely ignored, however.)
-
-For example: If you choose a subject called @samp{cat.gif (2/3)}, Gnus
-will find all the articles that match the regexp @samp{^cat.gif
-([0-9]+/[0-9]+).*$}.
-
-Subjects that are non-standard, like @samp{cat.gif (2/3) Part 6 of a
-series}, will not be properly recognized by any of the automatic viewing
-commands, and you have to mark the articles manually with @kbd{#}.

-@node Viewing Files
-@subsection Viewing Files
-@cindex viewing files
-@cindex pseudo-articles
-
-After decoding, if the file is some sort of archive, Gnus will attempt
-to unpack the archive and see if any of the files in the archive can be
-viewed.  For instance, if you have a gzipped tar file @file{pics.tar.gz}
-containing the files @file{pic1.jpg} and @file{pic2.gif}, Gnus will
-uncompress and de-tar the main file, and then view the two pictures.
-This unpacking process is recursive, so if the archive contains archives
-of archives, it'll all be unpacked.
-
-Finally, Gnus will normally insert a @dfn{pseudo-article} for each
-extracted file into the summary buffer.  If you go to these
-``articles'', you will be prompted for a command to run (usually Gnus
-will make a suggestion), and then the command will be run.

-
-@vindex gnus-view-pseudos-separately
-If @code{gnus-view-pseudos-separately} is non-@code{nil}, one

-@vindex gnus-signature-separator
-Each article is divided into two parts---the head and the body.  The
-body can be divided into a signature part and a text part.  The variable
-that says what is to be considered a signature is
-@code{gnus-signature-separator}.  This is normally the standard
-@samp{^-- $} as mandated by son-of-RFC 1036.  However, many people use
-non-standard signature separators, so this variable can also be a list
-of regular expressions to be tested, one by one.  (Searches are done
-from the end of the body towards the beginning.)  One likely value is:
-
-@lisp
-(setq gnus-signature-separator
-      '("^-- $"         ; The standard
-        "^-- *$"        ; A common mangling
-        "^-------*$"    ; Many people just use a looong
-                        ; line of dashes.  Shame!
-        "^ *--------*$" ; Double-shame!
-        "^________*$"   ; Underscores are also popular
-        "^========*$")) ; Pervert!
-@end lisp

-The more permissive you are, the more likely it is that you'll get false
-positives.
-
-@vindex gnus-signature-limit
-@code{gnus-signature-limit} provides a limit to what is considered a
-signature when displaying articles.
-
-@enumerate
-@item
-If it is an integer, no signature may be longer (in characters) than
-that integer.
-@item
-If it is a floating point number, no signature may be longer (in lines)
-than that number.
-@item
-If it is a function, the function will be called without any parameters,
-and if it returns @code{nil}, there is no signature in the buffer.
-@item
-If it is a string, it will be used as a regexp.  If it matches, the text
-in question is not a signature.
-@end enumerate
-
-This variable can also be a list where the elements may be of the types
-listed above.  Here's an example:
-
-@lisp
-(setq gnus-signature-limit
-      '(200.0 "^---*Forwarded article"))
-@end lisp
-
-This means that if there are more than 200 lines after the signature
-separator, or the text after the signature separator is matched by
-the regular expression @samp{^---*Forwarded article}, then it isn't a
-signature after all.

-
-If given a positive numerical prefix, fetch that many articles back into
-the ancestry.  If given a negative numerical prefix, fetch just that
-ancestor.  So if you say @kbd{3 ^}, Gnus will fetch the parent, the

-It can also be a list of select methods, as well as the special symbol
-@code{current}, which means to use the current select method.  If it
-is a list, Gnus will try all the methods in the list until it finds a

-Most of the mail backends support fetching by @code{Message-ID}, but do
-not do a particularly excellent job at it.  That is, @code{nnmbox} and
-@code{nnbabyl} are able to locate articles from any groups, while
-@code{nnml} and @code{nnfolder} are only able to locate articles that
-have been posted to the current group.  (Anything else would be too time

-@node Alternative Approaches
-@section Alternative Approaches
-
-Different people like to read news using different methods.  This being
-Gnus, we offer a small selection of minor modes for the summary buffers.
-
-@menu

-* Binary Groups::               Auto-decode all articles.

-
-
-@node Pick and Read
-@subsection Pick and Read
-@cindex pick and read
-
-Some newsreaders (like @code{nn} and, uhm, @code{Netnews} on VM/CMS) use
-a two-phased reading interface.  The user first marks in a summary
-buffer the articles she wants to read.  Then she starts reading the
-articles with just an article buffer displayed.
-
-@findex gnus-pick-mode
-@kindex M-x gnus-pick-mode
-Gnus provides a summary buffer minor mode that allows
-this---@code{gnus-pick-mode}.  This basically means that a few process
-mark commands become one-keystroke commands to allow easy marking, and
-it provides one additional command for switching to the summary buffer.
-
-Here are the available keystrokes when using pick mode:
-
-@table @kbd
-@item .
-@kindex . (Pick)
-@findex gnus-pick-article-or-thread
-Pick the article or thread on the current line
-(@code{gnus-pick-article-or-thread}).  If the variable
-@code{gnus-thread-hide-subtree} is true, then this key selects the
-entire thread when used at the first article of the thread.  Otherwise,
-it selects just the article. If given a numerical prefix, go to that
-thread or article and pick it.  (The line number is normally displayed
-at the beginning of the summary pick lines.)
-
-@item SPACE
-@kindex SPACE (Pick)
-@findex gnus-pick-next-page
-Scroll the summary buffer up one page (@code{gnus-pick-next-page}).  If
-at the end of the buffer, start reading the picked articles.
-
-@item u
-@kindex u (Pick)
-@findex gnus-pick-unmark-article-or-thread.
-Unpick the thread or article
-(@code{gnus-pick-unmark-article-or-thread}).  If the variable
-@code{gnus-thread-hide-subtree} is true, then this key unpicks the
-thread if used at the first article of the thread.  Otherwise it unpicks
-just the article.  You can give this key a numerical prefix to unpick
-the thread or article at that line.
-
-@item RET
-@kindex RET (Pick)
-@findex gnus-pick-start-reading
-@vindex gnus-pick-display-summary
-Start reading the picked articles (@code{gnus-pick-start-reading}).  If
-given a prefix, mark all unpicked articles as read first.  If
-@code{gnus-pick-display-summary} is non-@code{nil}, the summary buffer
-will still be visible when you are reading.
-
-@end table
-
-All the normal summary mode commands are still available in the
-pick-mode, with the exception of @kbd{u}.  However @kbd{!} is available
-which is mapped to the same function
-@code{gnus-summary-tick-article-forward}.
-
-If this sounds like a good idea to you, you could say:
-
-@lisp
-(add-hook 'gnus-summary-mode-hook 'gnus-pick-mode)
-@end lisp
-
-@vindex gnus-pick-mode-hook
-@code{gnus-pick-mode-hook} is run in pick minor mode buffers.
-
-@vindex gnus-mark-unpicked-articles-as-read
-If @code{gnus-mark-unpicked-articles-as-read} is non-@code{nil}, mark
-all unpicked articles as read.  The default is @code{nil}.
-
-@vindex gnus-summary-pick-line-format
-The summary line format in pick mode is slightly different from the
-standard format.  At the beginning of each line the line number is
-displayed.  The pick mode line format is controlled by the
-@code{gnus-summary-pick-line-format} variable (@pxref{Formatting
-Variables}).  It accepts the same format specs that
-@code{gnus-summary-line-format} does (@pxref{Summary Buffer Lines}).

-
-@item gnus-selected-tree-face
-@vindex gnus-selected-tree-face
-Face used for highlighting the selected article in the tree buffer.  The

-
-@item gnus-tree-line-format
-@vindex gnus-tree-line-format
-A format string for the tree nodes.  The name is a bit of a misnomer,

-@cindex velveeta
-@cindex spamming
-Marking cross-posted articles as read ensures that you'll never have to
-read the same article more than once.  Unless, of course, somebody has
-posted it to several groups separately.  Posting the same article to
-several groups (not cross-posting) is called @dfn{spamming}, and you are
-by law required to send nasty-grams to anyone who perpetrates such a
-heinous crime.  You may want to try NoCeM handling to filter out spam
-(@pxref{NoCeM}).
-
-Remember: Cross-posting is kinda ok, but posting the same article
-separately to several groups is not.  Massive cross-posting (aka.
-@dfn{velveeta}) is to be avoided at all costs, and you can even use the
-@code{gnus-summary-mail-crosspost-complaint} command to complain about
-excessive crossposting (@pxref{Summary Mail Commands}).
-
-@cindex cross-posting
-@cindex Xref
-@cindex @sc{nov}
-One thing that may cause Gnus to not do the cross-posting thing
-correctly is if you use an @sc{nntp} server that supports @sc{xover}
-(which is very nice, because it speeds things up considerably) which
-does not include the @code{Xref} header in its @sc{nov} lines.  This is
-Evil, but all too common, alas, alack.  Gnus tries to Do The Right Thing
-even with @sc{xover} by registering the @code{Xref} lines of all
-articles you actually read, but if you kill the articles, or just mark
-them as read without reading them, Gnus will not get a chance to snoop
-the @code{Xref} lines out of these articles, and will be unable to use
-the cross reference mechanism.
-
-@cindex LIST overview.fmt
-@cindex overview.fmt
-To check whether your @sc{nntp} server includes the @code{Xref} header
-in its overview files, try @samp{telnet your.nntp.server nntp},
-@samp{MODE READER} on @code{inn} servers, and then say @samp{LIST
-overview.fmt}.  This may not work, but if it does, and the last line you
-get does not read @samp{Xref:full}, then you should shout and whine at
-your news admin until she includes the @code{Xref} header in the
-overview files.
-
-@vindex gnus-nov-is-evil
-If you want Gnus to get the @code{Xref}s right all the time, you have to
-set @code{gnus-nov-is-evil} to @code{t}, which slows things down
-considerably.
-
-C'est la vie.
-
-For an alternative approach, @pxref{Duplicate Suppression}.
-
-
-@node Duplicate Suppression
-@section Duplicate Suppression
-
-By default, Gnus tries to make sure that you don't have to read the same
-article more than once by utilizing the crossposting mechanism
-(@pxref{Crosspost Handling}).  However, that simple and efficient
-approach may not work satisfactory for some users for various
-reasons.
-
-@enumerate
-@item
-The @sc{nntp} server may fail to generate the @code{Xref} header.  This
-is evil and not very common.
-
-@item
-The @sc{nntp} server may fail to include the @code{Xref} header in the
-@file{.overview} data bases.  This is evil and all too common, alas.
-
-@item
-You may be reading the same group (or several related groups) from
-different @sc{nntp} servers.
-
-@item
-You may be getting mail that duplicates articles posted to groups.
-@end enumerate
-
-I'm sure there are other situations where @code{Xref} handling fails as
-well, but these four are the most common situations.
-
-If, and only if, @code{Xref} handling fails for you, then you may
-consider switching on @dfn{duplicate suppression}.  If you do so, Gnus
-will remember the @code{Message-ID}s of all articles you have read or
-otherwise marked as read, and then, as if by magic, mark them as read
-all subsequent times you see them---in @emph{all} groups.  Using this
-mechanism is quite likely to be somewhat inefficient, but not overly
-so.  It's certainly preferable to reading the same articles more than
-once.
-
-Duplicate suppression is not a very subtle instrument.  It's more like a
-sledge hammer than anything else.  It works in a very simple
-fashion---if you have marked an article as read, it adds this Message-ID
-to a cache.  The next time it sees this Message-ID, it will mark the
-article as read with the @samp{M} mark.  It doesn't care what group it
-saw the article in.
-
-@table @code
-@item gnus-suppress-duplicates
-@vindex gnus-suppress-duplicates
-If non-@code{nil}, suppress duplicates.
-
-@item gnus-save-duplicate-list
-@vindex gnus-save-duplicate-list
-If non-@code{nil}, save the list of duplicates to a file.  This will
-make startup and shutdown take longer, so the default is @code{nil}.
-However, this means that only duplicate articles read in a single Gnus
-session are suppressed.
-
-@item gnus-duplicate-list-length
-@vindex gnus-duplicate-list-length
-This variable says how many @code{Message-ID}s to keep in the duplicate

-@item gnus-duplicate-file
-@vindex gnus-duplicate-file
-The name of the file to store the duplicate suppression list in.  The

-@end table
-
-If you have a tendency to stop and start Gnus often, setting
-@code{gnus-save-duplicate-list} to @code{t} is probably a good idea.  If
-you leave Gnus running for weeks on end, you may have it @code{nil}.  On
-the other hand, saving the list makes startup and shutdown much slower,
-so that means that if you stop and start Gnus often, you should set
-@code{gnus-save-duplicate-list} to @code{nil}.  Uhm.  I'll leave this up

-
-@item gnus-ignored-headers
-@vindex gnus-ignored-headers
-This variable is the reverse of @code{gnus-visible-headers}.  If this
-variable is set (and @code{gnus-visible-headers} is @code{nil}), it
-should be a regular expression that matches all lines that you want to
-hide.  All lines that do not match this variable will remain visible.
-
-For instance, if you just want to get rid of the @code{References} line
-and the @code{Xref} line, you might say:
-
-@lisp
-(setq gnus-ignored-headers "^References:\\|^Xref:")
-@end lisp
-
-This variable can also be a list of regexps to match headers to

-
-Note that if @code{gnus-visible-headers} is non-@code{nil}, this
-variable will have no effect.
-
-@end table
-
-@vindex gnus-sorted-header-list
-Gnus can also sort the headers for you.  (It does this by default.)  You
-can control the sorting by setting the @code{gnus-sorted-header-list}
-variable.  It is a list of regular expressions that says in what order
-the headers are to be displayed.
-
-For instance, if you want the name of the author of the article first,
-and then the subject, you might say something like:
-
-@lisp
-(setq gnus-sorted-header-list '("^From:" "^Subject:"))
-@end lisp
-
-Any headers that are to remain visible, but are not listed in this
-variable, will be displayed in random order after all the headers listed in this variable.
-
-@findex gnus-article-hide-boring-headers
-@vindex gnus-boring-article-headers
-You can hide further boring headers by setting
-@code{gnus-treat-hide-boring-header} to @code{head}.  What this function
-does depends on the @code{gnus-boring-article-headers} variable.  It's a
-list, but this list doesn't actually contain header names.  Instead is
-lists various @dfn{boring conditions} that Gnus can check and remove
-from sight.
-
-These conditions are:
-@table @code
-@item empty
-Remove all empty headers.
-@item followup-to
-Remove the @code{Followup-To} header if it is identical to the
-@code{Newsgroups} header.
-@item reply-to
-Remove the @code{Reply-To} header if it lists the same address as the
-@code{From} header.
-@item newsgroups
-Remove the @code{Newsgroups} header if it only contains the current group
-name.
-@item date
-Remove the @code{Date} header if the article is less than three days
-old.
-@item long-to
-Remove the @code{To} header if it is very long.
-@item many-to
-Remove all @code{To} headers if there are more than one.
-@end table
-
-To include the four three elements, you could say something like;
-
-@lisp
-(setq gnus-boring-article-headers
-      '(empty followup-to reply-to))
-@end lisp
-
-This is also the default value for this variable.

-@node Using MIME
-@section Using @sc{mime}
-@cindex @sc{mime}
-
-Mime is a standard for waving your hands through the air, aimlessly,
-while people stand around yawning.
-
-@sc{mime}, however, is a standard for encoding your articles, aimlessly,
-while all newsreaders die of fear.
-
-@sc{mime} may specify what character set the article uses, the encoding
-of the characters, and it also makes it possible to embed pictures and
-other naughty stuff in innocent-looking articles.
-
-@vindex gnus-display-mime-function
-@findex gnus-display-mime
-Gnus pushes @sc{mime} articles through @code{gnus-display-mime-function}
-to display the @sc{mime} parts.  This is @code{gnus-display-mime} by
-default, which creates a bundle of clickable buttons that can be used to
-display, save and manipulate the @sc{mime} objects.
-
-The following commands are available when you have placed point over a
-@sc{mime} button:
-
-@table @kbd
-@findex gnus-article-press-button
-@item RET (Article)
-@itemx BUTTON-2 (Article)
-Toggle displaying of the @sc{mime} object
-(@code{gnus-article-press-button}).
-
-@findex gnus-mime-view-part
-@item M-RET (Article)
-@itemx v (Article)
-Prompt for a method, and then view the @sc{mime} object using this
-method (@code{gnus-mime-view-part}).
-
-@findex gnus-mime-save-part
-@item o (Article)
-Prompt for a file name, and then save the @sc{mime} object
-(@code{gnus-mime-save-part}).
-
-@findex gnus-mime-copy-part
-@item c (Article)
-Copy the @sc{mime} object to a fresh buffer and display this buffer
-(@code{gnus-mime-copy-part}).
-
-@findex gnus-mime-view-part-as-type
-@item t (Article)
-View the @sc{mime} object as if it were a different @sc{mime} media type
-(@code{gnus-mime-view-part-as-type}. 
-
-@findex gnus-mime-pipe-part
-@item | (Article)
-Output the @sc{mime} object to a process (@code{gnus-mime-pipe-part}).
-@end table
-
-Gnus will display some @sc{mime} objects automatically.  The way Gnus
-determines which parts to do this with is described in the Emacs MIME
-manual.
-
-It might be best to just use the toggling functions from the article
-buffer to avoid getting nasty surprises.  (For instance, you enter the
-group @samp{alt.sing-a-long} and, before you know it, @sc{mime} has
-decoded the sound file in the article and some horrible sing-a-long song
-comes screaming out your speakers, and you can't find the volume button,
-because there isn't one, and people are starting to look at you, and you
-try to stop the program, but you can't, and you can't find the program
-to control the volume, and everybody else in the room suddenly decides
-to look at you disdainfully, and you'll feel rather stupid.)
-
-Any similarity to real events and people is purely coincidental.  Ahem.

-@node Customizing Articles
-@section Customizing Articles
-@cindex article customization
-
-A slew of functions for customizing how the articles are to look like
-exist.  You can call these functions interactively, or you can have them
-called automatically when you select the articles.
-
-To have them called automatically, you should set the corresponding
-``treatment'' variable.  For instance, to have headers hidden, you'd set
-@code{gnus-treat-hide-headers}.  Below is a list of variables that can
-be set, but first we discuss the values these variables can have.
-
-Note: Some values, while valid, make little sense.  Check the list below
-for sensible values.
-
-@enumerate
-@item
-@code{nil}: Don't do this treatment.
-
-@item
-@code{t}: Do this treatment on all body parts.
-
-@item
-@code{head}: Do the treatment on the headers.
-
-@item
-@code{last}: Do this treatment on the last part.
-
-@item
-An integer: Do this treatment on all body parts that have a length less
-than this number.
-
-@item
-A list of strings: Do this treatment on all body parts that are in
-articles that are read in groups that have names that match one of the
-regexps in the list.
-
-@item
-A list where the first element is not a string:
-
-The list is evaluated recursively.  The first element of the list is a
-predicate.  The following predicates are recognized: @code{or},
-@code{and}, @code{not} and @code{typep}.  Here's an example:
-
-@lisp
-(or last
-    (typep "text/x-vcard"))
-@end lisp
-
-@end enumerate
-
-You may have noticed that the word @dfn{part} is used here.  This refers
-to the fact that some messages are @sc{mime} multipart articles that may
-be divided into several parts.  Articles that are not multiparts are
-considered to contain just a single part.
-
-@vindex gnus-article-treat-types
-Are the treatments applied to all sorts of multipart parts?  Yes, if you
-want to, but by default, only @samp{text/plain} parts are given the
-treatment.  This is controlled by the @code{gnus-article-treat-types}
-variable, which is a list of regular expressions that are matched to the
-type of the part.  This variable is ignored if the value of the
-controlling variable is a predicate list, as described above.
-
-The following treatment options are available.  The easiest way to
-customize this is to examine the @code{gnus-article-treat} customization
-group. Values in brackets are suggested sensible values. Others are possible
-but those listed are probably sufficient for most people.

-When you press those magical @kbd{C-c C-c} keys to ship off your latest
-(extremely intelligent, of course) article, where does it go?
-
-Thank you for asking.  I hate you.
-
-@vindex gnus-post-method
-
-It can be quite complicated.  Normally, Gnus will use the same native
-server.  However.  If your native server doesn't allow posting, just
-reading, you probably want to use some other server to post your
-(extremely intelligent and fabulously interesting) articles.  You can
-then set the @code{gnus-post-method} to some other method:
-
-@lisp
-(setq gnus-post-method '(nnspool ""))
-@end lisp
-
-Now, if you've done this, and then this server rejects your article, or
-this server is down, what do you do then?  To override this variable you
-can use a non-zero prefix to the @kbd{C-c C-c} command to force using
-the ``current'' server for posting.
-
-If you give a zero prefix (i.e., @kbd{C-u 0 C-c C-c}) to that command,
-Gnus will prompt you for what method to use for posting.
-
-You can also set @code{gnus-post-method} to a list of select methods.
-If that's the case, Gnus will always prompt you for what method to use
-for posting.
-
-Finally, if you want to always post using the same select method as
-you're reading from (which might be convenient if you're reading lots of
-groups from different private servers), you can set this variable to
-@code{current}.
-

-posting:
-
-@table @code
-@item gnus-mailing-list-groups
-@findex gnus-mailing-list-groups
-@cindex mailing lists
-
-If your news server offers groups that are really mailing lists
-gatewayed to the @sc{nntp} server, you can read those groups without
-problems, but you can't post/followup to them without some difficulty.
-One solution is to add a @code{to-address} to the group parameters
-(@pxref{Group Parameters}).  An easier thing to do is set the
-@code{gnus-mailing-list-groups} to a regexp that matches the groups that
-really are mailing lists.  Then, at least, followups to the mailing
-lists will work most of the time.  Posting to these groups (@kbd{a}) is
-still a pain, though.
-
-@end table
-
-You may want to do spell-checking on messages that you send out.  Or, if
-you don't want to spell-check by hand, you could add automatic
-spell-checking via the @code{ispell} package:
-
-@cindex ispell
-@findex ispell-message
-@lisp
-(add-hook 'message-send-hook 'ispell-message)
-@end lisp
-
-
-@node Archived Messages
-@section Archived Messages
-@cindex archived messages
-@cindex sent messages
-
-Gnus provides a few different methods for storing the mail and news you
-send.  The default method is to use the @dfn{archive virtual server} to
-store the messages.  If you want to disable this completely, the
-@code{gnus-message-archive-group} variable should be @code{nil}, which
-is the default.
-
-@vindex gnus-message-archive-method
-@code{gnus-message-archive-method} says what virtual server Gnus is to
-use to store sent messages.  The default is:
-
-@lisp
-(nnfolder "archive"
-          (nnfolder-directory   "~/Mail/archive")
-          (nnfolder-active-file "~/Mail/archive/active")
-          (nnfolder-get-new-mail nil)
-          (nnfolder-inhibit-expiry t))
-@end lisp
-
-You can, however, use any mail select method (@code{nnml},
-@code{nnmbox}, etc.).  @code{nnfolder} is a quite likeable select method
-for doing this sort of thing, though.  If you don't like the default
-directory chosen, you could say something like:
-
-@lisp
-(setq gnus-message-archive-method
-      '(nnfolder "archive"
-                 (nnfolder-inhibit-expiry t)
-                 (nnfolder-active-file "~/News/sent-mail/active")
-                 (nnfolder-directory "~/News/sent-mail/")))
-@end lisp
-
-@vindex gnus-message-archive-group
-@cindex Gcc
-Gnus will insert @code{Gcc} headers in all outgoing messages that point
-to one or more group(s) on that server.  Which group to use is
-determined by the @code{gnus-message-archive-group} variable.
-
-This variable can be used to do the following:
-
-@itemize @bullet
-@item a string
-Messages will be saved in that group.
-@item a list of strings
-Messages will be saved in all those groups.
-@item an alist of regexps, functions and forms
-When a key ``matches'', the result is used.
-@item @code{nil}
-No message archiving will take place.  This is the default.
-@end itemize
-
-Let's illustrate:
-
-Just saving to a single group called @samp{MisK}:
-@lisp
-(setq gnus-message-archive-group "MisK")
-@end lisp
-
-Saving to two groups, @samp{MisK} and @samp{safe}:
-@lisp
-(setq gnus-message-archive-group '("MisK" "safe"))
-@end lisp
-
-Save to different groups based on what group you are in:
-@lisp
-(setq gnus-message-archive-group
-      '(("^alt" "sent-to-alt")
-        ("mail" "sent-to-mail")
-        (".*" "sent-to-misc")))
-@end lisp
-
-More complex stuff:
-@lisp
-(setq gnus-message-archive-group
-      '((if (message-news-p)
-            "misc-news"
-          "misc-mail")))
-@end lisp
-
-How about storing all news messages in one file, but storing all mail
-messages in one file per month:
-
-@lisp
-(setq gnus-message-archive-group
-      '((if (message-news-p)
-            "misc-news"
-          (concat "mail." (format-time-string "%Y-%m")))))
-@end lisp
-
-(XEmacs 19.13 doesn't have @code{format-time-string}, so you'll have to
-use a different value for @code{gnus-message-archive-group} there.)
-
-Now, when you send a message off, it will be stored in the appropriate
-group.  (If you want to disable storing for just one particular message,
-you can just remove the @code{Gcc} header that has been inserted.)  The
-archive group will appear in the group buffer the next time you start
-Gnus, or the next time you press @kbd{F} in the group buffer.  You can
-enter it and read the articles in it just like you'd read any other
-group.  If the group gets really big and annoying, you can simply rename
-if (using @kbd{G r} in the group buffer) to something
-nice---@samp{misc-mail-september-1995}, or whatever.  New messages will
-continue to be stored in the old (now empty) group.
-
-That's the default method of archiving sent messages.  Gnus offers a
-different way for the people who don't like the default method.  In that
-case you should set @code{gnus-message-archive-group} to @code{nil};
-this will disable archiving.
-
-@table @code
-@item gnus-outgoing-message-group
-@vindex gnus-outgoing-message-group
-All outgoing messages will be put in this group.  If you want to store
-all your outgoing mail and articles in the group @samp{nnml:archive},
-you set this variable to that value.  This variable can also be a list of
-group names.
-
-If you want to have greater control over what group to put each
-message in, you can set this variable to a function that checks the
-current newsgroup name and then returns a suitable group name (or list
-of names).
-
-This variable can be used instead of @code{gnus-message-archive-group},
-but the latter is the preferred method.

-All them variables, they make my head swim.
-
-So what if you want a different @code{Organization} and signature based
-on what groups you post to?  And you post both from your home machine
-and your work machine, and you want different @code{From} lines, and so
-on?
-
-@vindex gnus-posting-styles
-One way to do stuff like that is to write clever hooks that change the
-variables you need to have changed.  That's a bit boring, so somebody
-came up with the bright idea of letting the user specify these things in
-a handy alist.  Here's an example of a @code{gnus-posting-styles}
-variable:
-
-@lisp
-((".*"
-  (signature "Peace and happiness")
-  (organization "What me?"))
- ("^comp"
-  (signature "Death to everybody"))
- ("comp.emacs.i-love-it"
-  (organization "Emacs is it")))
-@end lisp
-
-As you might surmise from this example, this alist consists of several
-@dfn{styles}.  Each style will be applicable if the first element
-``matches'', in some form or other.  The entire alist will be iterated
-over, from the beginning towards the end, and each match will be
-applied, which means that attributes in later styles that match override
-the same attributes in earlier matching styles.  So
-@samp{comp.programming.literate} will have the @samp{Death to everybody}
-signature and the @samp{What me?} @code{Organization} header.
-
-The first element in each style is called the @code{match}.  If it's a
-string, then Gnus will try to regexp match it against the group name.
-If it is the symbol @code{header}, then Gnus will look for header that
-match the next element in the match, and compare that to the last header
-in the match.  If it's a function symbol, that function will be called
-with no arguments.  If it's a variable symbol, then the variable will be
-referenced.  If it's a list, then that list will be @code{eval}ed.  In
-any case, if this returns a non-@code{nil} value, then the style is said
-to @dfn{match}.
-
-Each style may contain a arbitrary amount of @dfn{attributes}.  Each
-attribute consists of a @code{(@var{name} . @var{value})} pair.  The
-attribute name can be one of @code{signature}, @code{signature-file},
-@code{organization}, @code{address}, @code{name} or @code{body}.  The
-attribute name can also be a string.  In that case, this will be used as
-a header name, and the value will be inserted in the headers of the
-article.  If the attribute name is @code{eval}, the form is evaluated,
-and the result is thrown away.
-
-The attribute value can be a string (used verbatim), a function with
-zero arguments (the return value will be used), a variable (its value
-will be used) or a list (it will be @code{eval}ed and the return value
-will be used).  The functions and sexps are called/@code{eval}ed in the
-message buffer that is being set up.  The headers of the current article
-are available through the @code{message-reply-headers} variable.
-
-If you wish to check whether the message you are about to compose is
-meant to be a news article or a mail message, you can check the values
-of the @code{message-news-p} and @code{message-mail-p} functions.
-
-@findex message-mail-p
-@findex message-news-p
-
-So here's a new example:
-
-@lisp
-(setq gnus-posting-styles
-      '((".*"
-         (signature-file "~/.signature")
-         (name "User Name")
-         ("X-Home-Page" (getenv "WWW_HOME"))
-         (organization "People's Front Against MWM"))
-        ("^rec.humor"
-         (signature my-funny-signature-randomizer))
-        ((equal (system-name) "gnarly")
-         (signature my-quote-randomizer))
-        ((message-news-p)
-         (signature my-news-signature))
-        ((header "From.*To" "larsi.*org")
-         (Organization "Somewhere, Inc."))
-        ((posting-from-work-p)
-         (signature-file "~/.work-signature")
-         (address "user@@bar.foo")
-         (body "You are fired.\n\nSincerely, your boss.")
-         (organization "Important Work, Inc"))

-@cindex drafts
-
-If you are writing a message (mail or news) and suddenly remember that
-you have a steak in the oven (or some pesto in the food processor, you
-craaazy vegetarians), you'll probably wish there was a method to save
-the message you are writing so that you can continue editing it some
-other day, and send it when you feel its finished.
-
-Well, don't worry about it.  Whenever you start composing a message of
-some sort using the Gnus mail and post commands, the buffer you get will
-automatically associate to an article in a special @dfn{draft} group.
-If you save the buffer the normal way (@kbd{C-x C-s}, for instance), the
-article will be saved there.  (Auto-save files also go to the draft
-group.)
-
-@cindex nndraft
-@vindex nndraft-directory
-The draft group is a special group (which is implemented as an
-@code{nndraft} group, if you absolutely have to know) called
-@samp{nndraft:drafts}.  The variable @code{nndraft-directory} says where
-@code{nndraft} is to store its files.  What makes this group special is
-that you can't tick any articles in it or mark any articles as
-read---all articles in the group are permanently unread.
-
-If the group doesn't exist, it will be created and you'll be subscribed
-to it.  The only way to make it disappear from the Group buffer is to
-unsubscribe it.

-@c If you're writing some super-secret message that you later want to
-@c encode with PGP before sending, you may wish to turn the auto-saving
-@c (and association with the draft group) off.  You never know who might be
-@c interested in reading all your extremely valuable and terribly horrible
-@c and interesting secrets.  The @kbd{C-c M-d}

-@c If you change your mind and want to turn the auto-saving back on again,
-@c @kbd{C-c C-d} (@code{gnus-associate-buffer-with-draft} does that.

-that.  You will be placed in a buffer where you left off.
-
-Rejected articles will also be put in this draft group (@pxref{Rejected
-Articles}).
-
-@findex gnus-draft-send-all-messages
-@findex gnus-draft-send-message
-If you have lots of rejected messages you want to post (or mail) without

-(@code{gnus-draft-send-message}).  This command understands the
-process/prefix convention (@pxref{Process/Prefix}).  The @kbd{D S}
-command (@code{gnus-draft-send-all-messages}) will ship off all messages
-in the buffer.
-
-If you have some messages that you wish not to send, you can use the
-@kbd{D t} (@code{gnus-draft-toggle-sending}) command to mark the message
-as unsendable.  This is a toggling command.

-@section Rejected Articles
-@cindex rejected articles
-
-Sometimes a news server will reject an article.  Perhaps the server
-doesn't like your face.  Perhaps it just feels miserable.  Perhaps
-@emph{there be demons}.  Perhaps you have included too much cited text.
-Perhaps the disk is full.  Perhaps the server is down.
-
-These situations are, of course, totally beyond the control of Gnus.
-(Gnus, of course, loves the way you look, always feels great, has angels
-fluttering around inside of it, doesn't care about how much cited text
-you include, never runs full and never goes down.)  So Gnus saves these
-articles until some later time when the server feels better.
-
-The rejected articles will automatically be put in a special draft group
-(@pxref{Drafts}).  When the server comes back up again, you'd then
-typically enter that group and send all the articles off.

-@node Select Methods
-@chapter Select Methods
-@cindex foreign groups
-@cindex select methods
-
-A @dfn{foreign group} is a group not read by the usual (or
-default) means.  It could be, for instance, a group from a different
-@sc{nntp} server, it could be a virtual group, or it could be your own
-personal mail group.
-
-A foreign group (or any group, really) is specified by a @dfn{name} and
-a @dfn{select method}.  To take the latter first, a select method is a
-list where the first element says what backend to use (e.g. @code{nntp},
-@code{nnspool}, @code{nnml}) and the second element is the @dfn{server
-name}.  There may be additional elements in the select method, where the
-value may have special meaning for the backend in question.
-
-One could say that a select method defines a @dfn{virtual server}---so
-we do just that (@pxref{The Server Buffer}).
-
-The @dfn{name} of the group is the name the backend will recognize the
-group as.
-
-For instance, the group @samp{soc.motss} on the @sc{nntp} server
-@samp{some.where.edu} will have the name @samp{soc.motss} and select
-method @code{(nntp "some.where.edu")}.  Gnus will call this group
-@samp{nntp+some.where.edu:soc.motss}, even though the @code{nntp}
-backend just knows this group as @samp{soc.motss}.
-
-The different methods all have their peculiarities, of course.

-@node The Server Buffer
-@section The Server Buffer
-
-Traditionally, a @dfn{server} is a machine or a piece of software that
-one connects to, and then requests information from.  Gnus does not
-connect directly to any real servers, but does all transactions through
-one backend or other.  But that's just putting one layer more between
-the actual media and Gnus, so we might just as well say that each
-backend represents a virtual server.
-
-For instance, the @code{nntp} backend may be used to connect to several
-different actual @sc{nntp} servers, or, perhaps, to many different ports
-on the same actual @sc{nntp} server.  You tell Gnus which backend to
-use, and what parameters to set by specifying a @dfn{select method}.
-
-These select method specifications can sometimes become quite
-complicated---say, for instance, that you want to read from the
-@sc{nntp} server @samp{news.funet.fi} on port number 13, which
-hangs if queried for @sc{nov} headers and has a buggy select.  Ahem.
-Anyways, if you had to specify that for each group that used this
-server, that would be too much work, so Gnus offers a way of naming
-select methods, which is what you do in the server buffer.
-
-To enter the server buffer, use the @kbd{^}
-(@code{gnus-group-enter-server-mode}) command in the group buffer.

-@node Example Methods
-@subsection Example Methods
-
-Most select methods are pretty simple and self-explanatory:
-
-@lisp
-(nntp "news.funet.fi")
-@end lisp
-
-Reading directly from the spool is even simpler:
-
-@lisp
-(nnspool "")
-@end lisp
-
-As you can see, the first element in a select method is the name of the
-backend, and the second is the @dfn{address}, or @dfn{name}, if you
-will.
-
-After these two elements, there may be an arbitrary number of
-@code{(@var{variable} @var{form})} pairs.
-
-To go back to the first example---imagine that you want to read from
-port 15 on that machine.  This is what the select method should
-look like then:
-
-@lisp
-(nntp "news.funet.fi" (nntp-port-number 15))
-@end lisp
-
-You should read the documentation to each backend to find out what
-variables are relevant, but here's an @code{nnmh} example:
-
-@code{nnmh} is a mail backend that reads a spool-like structure.  Say
-you have two structures that you wish to access: One is your private
-mail spool, and the other is a public one.  Here's the possible spec for
-your private mail:
-
-@lisp
-(nnmh "private" (nnmh-directory "~/private/mail/"))
-@end lisp
-
-(This server is then called @samp{private}, but you may have guessed
-that.)
-
-Here's the method for a public spool:
-
-@lisp
-(nnmh "public"
-      (nnmh-directory "/usr/information/spool/")
-      (nnmh-get-new-mail nil))
-@end lisp
-
-If you are behind a firewall and only have access to the @sc{nntp}
-server from the firewall machine, you can instruct Gnus to @code{rlogin}
-on the firewall machine and telnet from there to the @sc{nntp} server.
-Doing this can be rather fiddly, but your virtual server definition
-should probably look something like this:
-
-@lisp
-(nntp "firewall"
-      (nntp-address "the.firewall.machine")
-      (nntp-open-connection-function nntp-open-rlogin)
-      (nntp-end-of-line "\n")
-      (nntp-rlogin-parameters
-       ("telnet" "the.real.nntp.host" "nntp")))
-@end lisp
-
-If you want to use the wonderful @code{ssh} program to provide a
-compressed connection over the modem line, you could create a virtual
-server that would look something like this:
-
-@lisp
-(nntp "news"
-       (nntp-address "copper.uio.no")
-       (nntp-rlogin-program "ssh")
-       (nntp-open-connection-function nntp-open-rlogin)
-       (nntp-end-of-line "\n")
-       (nntp-rlogin-parameters
-        ("telnet" "news.uio.no" "nntp")))
-@end lisp
-
-This means that you have to have set up @code{ssh-agent} correctly to
-provide automatic authorization, of course.  And to get a compressed
-connection, you have to have the @samp{Compression} option in the
-@code{ssh} @file{config} file.
-
-
-@node Creating a Virtual Server
-@subsection Creating a Virtual Server
-
-If you're saving lots of articles in the cache by using persistent
-articles, you may want to create a virtual server to read the cache.
-
-First you need to add a new server.  The @kbd{a} command does that.  It
-would probably be best to use @code{nnspool} to read the cache.  You
-could also use @code{nnml} or @code{nnmh}, though.
-
-Type @kbd{a nnspool RET cache RET}.
-
-You should now have a brand new @code{nnspool} virtual server called
-@samp{cache}.  You now need to edit it to have the right definitions.
-Type @kbd{e} to edit the server.  You'll be entered into a buffer that
-will contain the following:
-
-@lisp
-(nnspool "cache")
-@end lisp
-
-Change that to:
-
-@lisp
-(nnspool "cache"
-         (nnspool-spool-directory "~/News/cache/")
-         (nnspool-nov-directory "~/News/cache/")
-         (nnspool-active-file "~/News/cache/active"))
-@end lisp
-
-Type @kbd{C-c C-c} to return to the server buffer.  If you now press
-@kbd{RET} over this virtual server, you should be entered into a browse
-buffer, and you should be able to enter any of the groups displayed.
-
-
-@node Server Variables
-@subsection Server Variables
-
-One sticky point when defining variables (both on backends and in Emacs
-in general) is that some variables are typically initialized from other
-variables when the definition of the variables is being loaded.  If you
-change the "base" variable after the variables have been loaded, you
-won't change the "derived" variables.
-
-This typically affects directory and file variables.  For instance,
-@code{nnml-directory} is @file{~/Mail/} by default, and all @code{nnml}
-directory variables are initialized from that variable, so
-@code{nnml-active-file} will be @file{~/Mail/active}.  If you define a
-new virtual @code{nnml} server, it will @emph{not} suffice to set just
-@code{nnml-directory}---you have to explicitly set all the file
-variables to be what you want them to be.  For a complete list of
-variables for each backend, see each backend's section later in this
-manual, but here's an example @code{nnml} definition:
-
-@lisp
-(nnml "public"
-      (nnml-directory "~/my-mail/")
-      (nnml-active-file "~/my-mail/active")
-      (nnml-newsgroups-file "~/my-mail/newsgroups"))

-@node Servers and Methods
-@subsection Servers and Methods
-
-Wherever you would normally use a select method
-(e.g. @code{gnus-secondary-select-method}, in the group select method,
-when browsing a foreign server) you can use a virtual server name
-instead.  This could potentially save lots of typing.  And it's nice all
-over.
-
-
-@node Unavailable Servers
-@subsection Unavailable Servers
-
-If a server seems to be unreachable, Gnus will mark that server as
-@code{denied}.  That means that any subsequent attempt to make contact
-with that server will just be ignored.  ``It can't be opened,'' Gnus
-will tell you, without making the least effort to see whether that is
-actually the case or not.
-
-That might seem quite naughty, but it does make sense most of the time.
-Let's say you have 10 groups subscribed to on server
-@samp{nephelococcygia.com}.  This server is located somewhere quite far
-away from you and the machine is quite slow, so it takes 1 minute just
-to find out that it refuses connection to you today.  If Gnus were to
-attempt to do that 10 times, you'd be quite annoyed, so Gnus won't
-attempt to do that.  Once it has gotten a single ``connection refused'',
-it will regard that server as ``down''.
-
-So, what happens if the machine was only feeling unwell temporarily?
-How do you test to see whether the machine has come up again?
-
-You jump to the server buffer (@pxref{The Server Buffer}) and poke it
-with the following commands:
-
-@table @kbd
-

-Subscribing to a foreign group from an @sc{nntp} server is rather easy.
-You just specify @code{nntp} as method and the address of the @sc{nntp}
-server as the, uhm, address.
-
-If the @sc{nntp} server is located at a non-standard port, setting the
-third element of the select method to this port number should allow you
-to connect to the right port.  You'll have to edit the group info for
-that (@pxref{Foreign Groups}).
-
-The name of the foreign group can be the same as a native group.  In
-fact, you can subscribe to the same group from as many different servers
-you feel like.  There will be no name collisions.
-
-The following variables can be used to create a virtual @code{nntp}

-
-@table @code
-
-@item nntp-server-opened-hook
-@vindex nntp-server-opened-hook
-@cindex @sc{mode reader}
-@cindex authinfo
-@cindex authentification

-@findex nntp-send-authinfo
-@findex nntp-send-mode-reader
-is run after a connection has been made.  It can be used to send
-commands to the @sc{nntp} server after it has been contacted.  By
-default it sends the command @code{MODE READER} to the server with the
-@code{nntp-send-mode-reader} function.  This function should always be
-present in this hook.
-
-@item nntp-authinfo-function
-@vindex nntp-authinfo-function
-@findex nntp-send-authinfo
-@vindex nntp-authinfo-file
-This function will be used to send @samp{AUTHINFO} to the @sc{nntp}
-server.  The default function is @code{nntp-send-authinfo}, which looks
-through your @file{~/.authinfo} (or whatever you've set the
-@code{nntp-authinfo-file} variable to) for applicable entries.  If none
-are found, it will prompt you for a login name and a password.  The
-format of the @file{~/.authinfo} file is (almost) the same as the
-@code{ftp} @file{~/.netrc} file, which is defined in the @code{ftp}
-manual page, but here are the salient facts:
-
-@enumerate
-@item
-The file contains one or more line, each of which define one server.
-
-@item
-Each line may contain an arbitrary number of token/value pairs.  The
-valid tokens include @samp{machine}, @samp{login}, @samp{password},
-@samp{default} and @samp{force}.  (The latter is not a valid
-@file{.netrc}/@code{ftp} token, which is the only way the
-@file{.authinfo} file format deviates from the @file{.netrc} file
-format.)
-
-@end enumerate
-
-Here's an example file:
-
-@example
-machine news.uio.no login larsi password geheimnis
-machine nntp.ifi.uio.no login larsi force yes
-@end example
-
-The token/value pairs may appear in any order; @samp{machine} doesn't
-have to be first, for instance.
-
-In this example, both login name and password have been supplied for the
-former server, while the latter has only the login name listed, and the
-user will be prompted for the password.  The latter also has the
-@samp{force} tag, which means that the authinfo will be sent to the
-@var{nntp} server upon connection; the default (i.e., when there is not
-@samp{force} tag) is to not send authinfo to the @var{nntp} server
-until the @var{nntp} server asks for it.
-
-You can also add @samp{default} lines that will apply to all servers
-that don't have matching @samp{machine} lines.
-
-@example
-default force yes
-@end example
-
-This will force sending @samp{AUTHINFO} commands to all servers not
-previously mentioned.
-
-Remember to not leave the @file{~/.authinfo} file world-readable.
-
-@item nntp-server-action-alist
-@vindex nntp-server-action-alist
-This is a list of regexps to match on server types and actions to be
-taken when matches are made.  For instance, if you want Gnus to beep
-every time you connect to innd, you could say something like:
-
-@lisp
-(setq nntp-server-action-alist
-      '(("innd" (ding))))
-@end lisp
-
-You probably don't want to do that, though.
-
-The default value is
-
-@lisp
-'(("nntpd 1\\.5\\.11t"
-   (remove-hook 'nntp-server-opened-hook 'nntp-send-mode-reader)))
-@end lisp
-
-This ensures that Gnus doesn't send the @code{MODE READER} command to
-nntpd 1.5.11t, since that command chokes that server, I've been told.
-
-@item nntp-maximum-request
-@vindex nntp-maximum-request
-If the @sc{nntp} server doesn't support @sc{nov} headers, this backend
-will collect headers by sending a series of @code{head} commands.  To
-speed things up, the backend sends lots of these commands without
-waiting for reply, and then reads all the replies.  This is controlled
-by the @code{nntp-maximum-request} variable, and is 400 by default.  If
-your network is buggy, you should set this to 1.
-
-@item nntp-connection-timeout
-@vindex nntp-connection-timeout
-If you have lots of foreign @code{nntp} groups that you connect to
-regularly, you're sure to have problems with @sc{nntp} servers not
-responding properly, or being too loaded to reply within reasonable
-time.  This is can lead to awkward problems, which can be helped
-somewhat by setting @code{nntp-connection-timeout}.  This is an integer
-that says how many seconds the @code{nntp} backend should wait for a
-connection before giving up.  If it is @code{nil}, which is the default,
-no timeouts are done.
-
-@c @item nntp-command-timeout
-@c @vindex nntp-command-timeout
-@c @cindex PPP connections
-@c @cindex dynamic IP addresses
-@c If you're running Gnus on a machine that has a dynamically assigned
-@c address, Gnus may become confused.  If the address of your machine
-@c changes after connecting to the @sc{nntp} server, Gnus will simply sit
-@c waiting forever for replies from the server.  To help with this
-@c unfortunate problem, you can set this command to a number.  Gnus will
-@c then, if it sits waiting for a reply from the server longer than that
-@c number of seconds, shut down the connection, start a new one, and resend
-@c the command.  This should hopefully be transparent to the user.  A
-@c likely number is 30 seconds.
-@c
-@c @item nntp-retry-on-break
-@c @vindex nntp-retry-on-break
-@c If this variable is non-@code{nil}, you can also @kbd{C-g} if Gnus

-@node Mail in a Newsreader
-@subsection Mail in a Newsreader
-
-If you are used to traditional mail readers, but have decided to switch 
-to reading mail with Gnus, you may find yourself experiencing something
-of a culture shock.
-
-Gnus does not behave like traditional mail readers.  If you want to make 
-it behave that way, you can, but it's an uphill battle.
-
-Gnus, by default, handles all its groups using the same approach.  This
-approach is very newsreaderly---you enter a group, see the new/unread
-messages, and when you read the messages, they get marked as read, and
-you don't see them any more.  (Unless you explicitly ask for them.)
-
-In particular, you do not do anything explicitly to delete messages.
-
-Does this mean that all the messages that have been marked as read are
-deleted?  How awful!
-
-But, no, it means that old messages are @dfn{expired} according to some
-scheme or other.  For news messages, the expire process is controlled by 
-the news administrator; for mail, the expire process is controlled by
-you.  The expire process for mail is covered in depth in @pxref{Expiring
-Mail}.
-
-What many Gnus users find, after using it a while for both news and
-mail, is that the transport mechanism has very little to do with how
-they want to treat a message.
-
-Many people subscribe to several mailing lists.  These are transported
-via SMTP, and are therefore mail.  But we might go for weeks without
-answering, or even reading these messages very carefully. We may not
-need to save them because if we should need to read one again, they are
-archived somewhere else.
-
-Some people have local news groups which have only a handful of readers.
-These are transported via NNTP, and are therefore news.  But we may need
-to read and answer a large fraction of the messages very carefully in
-order to do our work.  And there may not be an archive, so we may need
-to save the interesting messages the same way we would personal mail.
-
-The important distinction turns out to be not the transport mechanism,
-but other factors such as how interested we are in the subject matter,
-or how easy it is to retrieve the message if we need to read it again.
-
-Gnus provides many options for sorting mail into ``groups'' which behave
-like newsgroups, and for treating each group (whether mail or news)
-differently.
-
-Some users never get comfortable using the Gnus (ahem) paradigm and wish
-that Gnus should grow up and be a male, er, mail reader.  It is possible
-to whip Gnus into a more mailreaderly being, but, as said before, it's
-not easy.  People who prefer proper mail readers should try @sc{vm}
-instead, which is an excellent, and proper, mail reader.
-
-I don't mean to scare anybody off, but I want to make it clear that you
-may be required to learn a new way of thinking about messages.  After
-you've been subjected to The Gnus Way, you will come to love it.  I can
-guarantee it.  (At least the guy who sold me the Emacs Subliminal
-Brain-Washing Functions that I've put into Gnus did guarantee it.  You
-Will Be Assimilated.  You Love Gnus.  You Love The Gnus Mail Way.
-You Do.)
-
-
-@node Getting Started Reading Mail
-@subsection Getting Started Reading Mail
-
-It's quite easy to use Gnus to read your new mail.  You just plonk the
-mail backend of your choice into @code{gnus-secondary-select-methods},
-and things will happen automatically.
-
-For instance, if you want to use @code{nnml} (which is a "one file per
-mail" backend), you could put the following in your @file{.gnus} file:
-
-@lisp
-(setq gnus-secondary-select-methods
-      '((nnml "private")))
-@end lisp
-
-Now, the next time you start Gnus, this backend will be queried for new
-articles, and it will move all the messages in your spool file to its
-directory, which is @code{~/Mail/} by default.  The new group that will
-be created (@samp{mail.misc}) will be subscribed, and you can read it
-like any other group.
-
-You will probably want to split the mail into several groups, though:
-
-@lisp
-(setq nnmail-split-methods
-      '(("junk" "^From:.*Lars Ingebrigtsen")
-        ("crazy" "^Subject:.*die\\|^Organization:.*flabby")
-        ("other" "")))
-@end lisp
-
-This will result in three new @code{nnml} mail groups being created:
-@samp{nnml:junk}, @samp{nnml:crazy}, and @samp{nnml:other}.  All the
-mail that doesn't fit into the first two groups will be placed in the
-last group.
-
-This should be sufficient for reading mail with Gnus.  You might want to
-give the other sections in this part of the manual a perusal, though.
-Especially @pxref{Choosing a Mail Backend} and @pxref{Expiring Mail}.
-
-
-@node Splitting Mail
-@subsection Splitting Mail
-@cindex splitting mail
-@cindex mail splitting
-
-@vindex nnmail-split-methods
-The @code{nnmail-split-methods} variable says how the incoming mail is
-to be split into groups.
-
-@lisp
-(setq nnmail-split-methods
-  '(("mail.junk" "^From:.*Lars Ingebrigtsen")
-    ("mail.crazy" "^Subject:.*die\\|^Organization:.*flabby")
-    ("mail.other" "")))
-@end lisp
-
-This variable is a list of lists, where the first element of each of
-these lists is the name of the mail group (they do not have to be called
-something beginning with @samp{mail}, by the way), and the second
-element is a regular expression used on the header of each mail to
-determine if it belongs in this mail group.  The first string may
-contain @samp{\\1} forms, like the ones used by @code{replace-match} to
-insert sub-expressions from the matched text.  For instance:
-
-@lisp
-("list.\\1" "From:.* \\(.*\\)-list@@majordomo.com")
-@end lisp
-
-The second element can also be a function.  In that case, it will be
-called narrowed to the headers with the first element of the rule as the
-argument.  It should return a non-@code{nil} value if it thinks that the
-mail belongs in that group.
-
-The last of these groups should always be a general one, and the regular
-expression should @emph{always} be @samp{} so that it matches any mails
-that haven't been matched by any of the other regexps.  (These rules are
-processed from the beginning of the alist toward the end.  The first
-rule to make a match will "win", unless you have crossposting enabled.
-In that case, all matching rules will "win".)
-
-If you like to tinker with this yourself, you can set this variable to a
-function of your choice.  This function will be called without any
-arguments in a buffer narrowed to the headers of an incoming mail
-message.  The function should return a list of group names that it
-thinks should carry this mail message.
-
-Note that the mail backends are free to maul the poor, innocent,
-incoming headers all they want to.  They all add @code{Lines} headers;
-some add @code{X-Gnus-Group} headers; most rename the Unix mbox
-@code{From<SPACE>} line to something else.
-
-@vindex nnmail-crosspost
-The mail backends all support cross-posting.  If several regexps match,
-the mail will be ``cross-posted'' to all those groups.
-@code{nnmail-crosspost} says whether to use this mechanism or not.  Note
-that no articles are crossposted to the general (@samp{}) group.
-
-@vindex nnmail-crosspost-link-function
-@cindex crosspost
-@cindex links
-@code{nnmh} and @code{nnml} makes crossposts by creating hard links to
-the crossposted articles.  However, not all file systems support hard
-links.  If that's the case for you, set
-@code{nnmail-crosspost-link-function} to @code{copy-file}.  (This
-variable is @code{add-name-to-file} by default.)
-
-@kindex M-x nnmail-split-history
-@kindex nnmail-split-history
-If you wish to see where the previous mail split put the messages, you

-
-Gnus gives you all the opportunity you could possibly want for shooting
-yourself in the foot.  Let's say you create a group that will contain
-all the mail you get from your boss.  And then you accidentally
-unsubscribe from the group.  Gnus will still put all the mail from your
-boss in the unsubscribed group, and so, when your boss mails you ``Have
-that report ready by Monday or you're fired!'', you'll never see it and,
-come Tuesday, you'll still believe that you're gainfully employed while
-you really should be out collecting empty bottles to save up for next

-
-@item :fetchflag
-How to flag fetched articles on the server, the default @samp{\Deleted}

-
-@vindex mail-sources
-@vindex nnmail-spool-file
-The way to actually tell Gnus where to get new mail from is to set
-@code{mail-sources} to a list of mail source specifiers
-(@pxref{Mail Source Specifiers}).
-
-If this variable (and the obsolescent @code{nnmail-spool-file}) is
-@code{nil}, the mail backends will never attempt to fetch mail by
-themselves.
-
-If you want to fetch mail both from your local spool as well as a POP
-mail server, you'd say something like:
-
-@lisp
-(setq mail-sources
-      '((file)
-        (pop :server "pop3.mail.server"
-             :password "secret")))

-
-When you use a mail backend, Gnus will slurp all your mail from your

-
-@table @code
-@vindex nnmail-read-incoming-hook

-
-@vindex nnmail-split-hook
-@item nnmail-split-hook
-@findex article-decode-encoded-words
-@findex RFC1522 decoding
-@findex RFC2047 decoding
-Hook run in the buffer where the mail headers of each message is kept
-just before the splitting based on these headers is done.  The hook is
-free to modify the buffer contents in any way it sees fit---the buffer
-is discarded after the splitting has been done, and no changes performed
-in the buffer will show up in any files.
-@code{gnus-article-decode-encoded-words} is one likely function to add
-to this hook.

-starting to handle the new mail) and
-@code{nnmail-post-get-new-mail-hook} (is called when the mail handling
-is done).  Here's and example of using these two hooks to change the

-@item nnmail-use-long-file-names
-@vindex nnmail-use-long-file-names
-If non-@code{nil}, the mail backends will use long file and directory

-If the rather simple, standard method for specifying how to split mail
-doesn't allow you to do what you want, you can set
-@code{nnmail-split-methods} to @code{nnmail-split-fancy}.  Then you can
-play with the @code{nnmail-split-fancy} variable.
-
-Let's look at an example value of this variable first:
-
-@lisp
-;; Messages from the mailer daemon are not crossposted to any of

-;; from real errors.

-@end lisp
-
-This variable has the format of a @dfn{split}.  A split is a (possibly)
-recursive structure where each split may contain other splits.  Here are
-the five possible split syntaxes:
-
-@enumerate
-
-@item
-@samp{group}: If the split is a string, that will be taken as a group
-name.  Normal regexp match expansion will be done.  See below for
-examples.
-
-@item
-@code{(@var{field} @var{value} @var{[- restrict [- restrict [@dots{}]]]} 
-@var{split})}: If the split is a list, the first element of which is a
-string, then store the message as specified by @var{split}, if header
-@var{field} (a regexp) contains @var{value} (also a regexp).  If
-@var{restrict} (yet another regexp) matches some string after
-@var{field} and before the end of the matched @var{value}, the
-@var{split} is ignored.  If none of the @var{restrict} clauses match,
-@var{split} is processed.
-
-@item
-@code{(| @var{split}@dots{})}: If the split is a list, and the first
-element is @code{|} (vertical bar), then process each @var{split} until
-one of them matches.  A @var{split} is said to match if it will cause
-the mail message to be stored in one or more groups.
-
-@item
-@code{(& @var{split}@dots{})}: If the split is a list, and the first
-element is @code{&}, then process all @var{split}s in the list.
-
-@item
-@code{junk}: If the split is the symbol @code{junk}, then don't save
-this message. Use with extreme caution.
-
-@item
-@code{(: @var{function} @var{arg1} @var{arg2} @dots{})}:  If the split is
-a list, and the first element is @code{:}, then the second element will
-be called as a function with @var{args} given as arguments.  The
-function should return a @var{split}.
-
-@item
-@code{(! @var{func} @var{split})}: If the split is a list, and the first
-element is @code{!}, then SPLIT will be processed, and FUNC will be
-called as a function with the result of SPLIT as argument. FUNC should
-return a split.
-
-@item
-@code{nil}: If the split is @code{nil}, it is ignored.
-
-@end enumerate
-
-In these splits, @var{field} must match a complete field name.
-@var{value} must match a complete word according to the fundamental mode
-syntax table.  You can use @code{.*} in the regexps to match partial
-field names or words.  In other words, all @var{value}'s are wrapped in
-@samp{\<} and @samp{\>} pairs.
-
-@vindex nnmail-split-abbrev-alist
-@var{field} and @var{value} can also be lisp symbols, in that case they
-are expanded as specified by the variable
-@code{nnmail-split-abbrev-alist}.  This is an alist of cons cells, where
-the @code{car} of a cell contains the key, and the @code{cdr} contains the associated
-value.
-
-@vindex nnmail-split-fancy-syntax-table
-@code{nnmail-split-fancy-syntax-table} is the syntax table in effect
-when all this splitting is performed.
-
-If you want to have Gnus create groups dynamically based on some
-information in the headers (i.e., do @code{replace-match}-like
-substitutions in the group names), you can say things like:
-
-@example
-(any "debian-\\b\\(\\w+\\)@@lists.debian.org" "mail.debian.\\1")
-@end example
-
-In this example, messages sent to @samp{debian-foo@@lists.debian.org}
-will be filed in @samp{mail.debian.foo}.
-
-If the string contains the element @samp{\&}, then the previously
-matched string will be substituted.  Similarly, the elements @samp{\\1}
-up to @samp{\\9} will be substituted with the text matched by the
-groupings 1 through 9.

-@node Group Mail Splitting
-@subsection Group Mail Splitting
-@cindex mail splitting
-@cindex group mail splitting
-
-@findex gnus-group-split
-If you subscribe to dozens of mailing lists but you don't want to
-maintain mail splitting rules manually, group mail splitting is for you.
-You just have to set @var{to-list} and/or @var{to-address} in group
-parameters or group customization and set @code{nnmail-split-methods} to
-@code{gnus-group-split}.  This splitting function will scan all groups
-for those parameters and split mail accordingly, i.e., messages posted
-from or to the addresses specified in the parameters @var{to-list} or
-@var{to-address} of a mail group will be stored in that group.
-
-Sometimes, mailing lists have multiple addresses, and you may want mail
-splitting to recognize them all: just set the @var{extra-aliases} group
-parameter to the list of additional addresses and it's done.  If you'd
-rather use a regular expression, set @var{split-regexp}.
-
-All these parameters in a group will be used to create an
-@code{nnmail-split-fancy} split, in which the @var{field} is @samp{any},
-the @var{value} is a single regular expression that matches
-@var{to-list}, @var{to-address}, all of @var{extra-aliases} and all
-matches of @var{split-regexp}, and the @var{split} is the name of the
-group.  @var{restrict}s are also supported: just set the
-@var{split-exclude} parameter to a list of regular expressions.
-
-If you can't get the right split to be generated using all these
-parameters, or you just need something fancier, you can set the
-parameter @var{split-spec} to an @code{nnmail-split-fancy} split.  In
-this case, all other aforementioned parameters will be ignored by
-@code{gnus-group-split}.  In particular, @var{split-spec} may be set to
-@code{nil}, in which case the group will be ignored by
-@code{gnus-group-split}.
-
-@vindex gnus-group-split-default-catch-all-group
-@code{gnus-group-split} will do cross-posting on all groups that match,
-by defining a single @code{&} fancy split containing one split for each
-group.  If a message doesn't match any split, it will be stored in the
-group named in @code{gnus-group-split-default-catch-all-group}, unless
-some group has @var{split-spec} set to @code{catch-all}, in which case
-that group is used as the catch-all group.  Note that, in this case,
-there's no cross-posting, as a @code{|} fancy split encloses the
-@code{&} split and the catch-all group.
-
-It's time for an example.  Assume the following group parameters have
-been defined:
-
-@example
-nnml:mail.bar:
-((to-address . "bar@@femail.com")
- (split-regexp . ".*@@femail\\.com"))
-nnml:mail.foo:
-((to-list . "foo@@nowhere.gov")
- (extra-aliases "foo@@localhost" "foo-redist@@home")
- (split-exclude "bugs-foo" "rambling-foo")
- (admin-address . "foo-request@@nowhere.gov"))
-nnml:mail.others:
-((split-spec . catch-all))
-@end example
-
-Setting @code{nnmail-split-methods} to @code{gnus-group-split} will
-behave as if @code{nnmail-split-fancy} had been selected and variable
-@code{nnmail-split-fancy} had been set as follows:
-
-@lisp
-(| (& (any "\\(bar@@femail\\.com\\|.*@@femail\\.com\\)" "mail.bar")
-      (any "\\(foo@@nowhere\\.gov\\|foo@@localhost\\|foo-redist@@home\\)"
-           - "bugs-foo" - "rambling-foo" "mail.foo"))
-   "mail.others")
-@end lisp
-
-@findex gnus-group-split-fancy
-If you'd rather not use group splitting for all your mail groups, you
-may use it for only some of them, by using @code{nnmail-split-fancy}
-splits like this:
-
-@lisp
-(: gnus-mlsplt-fancy GROUPS NO-CROSSPOST CATCH-ALL)
-@end lisp
-
-@var{groups} may be a regular expression or a list of group names whose
-parameters will be scanned to generate the output split.
-@var{no-crosspost} can be used to disable cross-posting; in this case, a
-single @code{|} split will be output.  @var{catch-all} may be the name
-of a group to be used as the default catch-all group.  If
-@var{catch-all} is @code{nil}, or if @var{split-regexp} matches the
-empty string in any selected group, no catch-all split will be issued.
-Otherwise, if some group has @var{split-spec} set to @code{catch-all},
-this group will override the value of the @var{catch-all} argument.
-
-@findex gnus-group-split-setup
-Unfortunately, scanning all groups and their parameters can be quite
-slow, especially considering that it has to be done for every message.
-But don't despair!  The function @code{gnus-group-split-setup} can be
-used to select @code{gnus-group-split} in a much more efficient way.  It
-sets @code{nnmail-split-methods} to @code{nnmail-split-fancy} and sets
-@code{nnmail-split-fancy} to the split produced by
-@code{gnus-group-split-fancy}.  Thus, the group parameters are only
-scanned once, no matter how many messages are split.
-
-@findex gnus-group-split-update
-However, if you change group parameters, you have to update
-@code{nnmail-split-fancy} manually.  You can do it by running
-@code{gnus-group-split-update}.  If you'd rather have it updated
-automatically, just tell @code{gnus-group-split-setup} to do it for
-you.  For example, add to your @file{.gnus}:
-
-@lisp
-(gnus-group-split-setup AUTO-UPDATE CATCH-ALL)
-@end lisp
-
-If @var{auto-update} is non-@code{nil}, @code{gnus-group-split-update}
-will be added to @code{nnmail-pre-get-new-mail-hook}, so you won't ever
-have to worry about updating @code{nnmail-split-fancy} again.  If you
-don't omit @var{catch-all} (it's optional),
-@code{gnus-group-split-default-catch-all-group} will be set to its
-value.
-
-@vindex gnus-group-split-updated-hook
-Because you may want to change @code{nnmail-split-fancy} after it is set
-by @code{gnus-group-split-update}, this function will run
-@code{gnus-group-split-updated-hook} just before finishing.

-backends, you'll probably wish to have that old mail incorporated into
-your mail groups.
-
-Doing so can be quite easy.
-
-To take an example: You're reading mail using @code{nnml}
-(@pxref{Mail Spool}), and have set @code{nnmail-split-methods} to a
-satisfactory value (@pxref{Splitting Mail}).  You have an old Unix mbox
-file filled with important, but old, mail.  You want to move it into
-your @code{nnml} groups.
-
-Here's how:
-
-@enumerate
-@item
-Go to the group buffer.
-
-@item
-Type `G f' and give the path to the mbox file when prompted to create an
-@code{nndoc} group from the mbox file (@pxref{Foreign Groups}).
-
-@item
-Type `SPACE' to enter the newly created group.
-
-@item
-Type `M P b' to process-mark all articles in this group's buffer
-(@pxref{Setting Process Marks}).
-
-@item
-Type `B r' to respool all the process-marked articles, and answer
-@samp{nnml} when prompted (@pxref{Mail Group Commands}).
-@end enumerate
-
-All the mail messages in the mbox file will now also be spread out over
-all your @code{nnml} groups.  Try entering them and check whether things
-have gone without a glitch.  If things look ok, you may consider
-deleting the mbox file, but I wouldn't do that unless I was absolutely
-sure that all the mail has ended up where it should be.
-
-Respooling is also a handy thing to do if you're switching from one mail
-backend to another.  Just respool all the mail in the old mail groups
-using the new mail backend.

-
-@node Expiring Mail
-@subsection Expiring Mail
-@cindex article expiry
-
-Traditional mail readers have a tendency to remove mail articles when
-you mark them as read, in some way.  Gnus takes a fundamentally
-different approach to mail reading.
-
-Gnus basically considers mail just to be news that has been received in
-a rather peculiar manner.  It does not think that it has the power to
-actually change the mail, or delete any mail messages.  If you enter a
-mail group, and mark articles as ``read'', or kill them in some other
-fashion, the mail articles will still exist on the system.  I repeat:
-Gnus will not delete your old, read mail.  Unless you ask it to, of
-course.
-
-To make Gnus get rid of your unwanted mail, you have to mark the
-articles as @dfn{expirable}.  This does not mean that the articles will
-disappear right away, however.  In general, a mail article will be
-deleted from your system if, 1) it is marked as expirable, AND 2) it is
-more than one week old.  If you do not mark an article as expirable, it
-will remain on your system until hell freezes over.  This bears
-repeating one more time, with some spurious capitalizations: IF you do
-NOT mark articles as EXPIRABLE, Gnus will NEVER delete those ARTICLES.
-
-@vindex gnus-auto-expirable-newsgroups
-You do not have to mark articles as expirable by hand.  Groups that
-match the regular expression @code{gnus-auto-expirable-newsgroups} will
-have all articles that you read marked as expirable automatically.  All
-articles marked as expirable have an @samp{E} in the first
-column in the summary buffer.
-
-By default, if you have auto expiry switched on, Gnus will mark all the
-articles you read as expirable, no matter if they were read or unread
-before.  To avoid having articles marked as read marked as expirable
-automatically, you can put something like the following in your
-@file{.gnus} file:
-
-@vindex gnus-mark-article-hook
-@lisp
-(remove-hook 'gnus-mark-article-hook
-             'gnus-summary-mark-read-and-unread-as-read)
-(add-hook 'gnus-mark-article-hook 'gnus-summary-mark-unread-as-read)
-@end lisp
-
-Note that making a group auto-expirable doesn't mean that all read
-articles are expired---only the articles marked as expirable
-will be expired.  Also note that using the @kbd{d} command won't make
-groups expirable---only semi-automatic marking of articles as read will
-mark the articles as expirable in auto-expirable groups.
-
-Let's say you subscribe to a couple of mailing lists, and you want the
-articles you have read to disappear after a while:
-
-@lisp
-(setq gnus-auto-expirable-newsgroups
-      "mail.nonsense-list\\|mail.nice-list")
-@end lisp
-
-Another way to have auto-expiry happen is to have the element
-@code{auto-expire} in the group parameters of the group.
-
-If you use adaptive scoring (@pxref{Adaptive Scoring}) and
-auto-expiring, you'll have problems.  Auto-expiring and adaptive scoring
-don't really mix very well.
-
-@vindex nnmail-expiry-wait
-The @code{nnmail-expiry-wait} variable supplies the default time an
-expirable article has to live.  Gnus starts counting days from when the
-message @emph{arrived}, not from when it was sent.  The default is seven
-days.
-
-Gnus also supplies a function that lets you fine-tune how long articles
-are to live, based on what group they are in.  Let's say you want to
-have one month expiry period in the @samp{mail.private} group, a one day
-expiry period in the @samp{mail.junk} group, and a six day expiry period
-everywhere else:
-
-@vindex nnmail-expiry-wait-function
-@lisp
-(setq nnmail-expiry-wait-function
-      (lambda (group)
-       (cond ((string= group "mail.private")
-               31)
-             ((string= group "mail.junk")
-               1)
-             ((string= group "important")
-               'never)
-             (t
-               6))))
-@end lisp
-
-The group names this function is fed are ``unadorned'' group
-names---no @samp{nnml:} prefixes and the like.
-
-The @code{nnmail-expiry-wait} variable and
-@code{nnmail-expiry-wait-function} function can either be a number (not
-necessarily an integer) or one of the symbols @code{immediate} or
-@code{never}.
-
-You can also use the @code{expiry-wait} group parameter to selectively
-change the expiry period (@pxref{Group Parameters}).
-
-@vindex nnmail-keep-last-article
-If @code{nnmail-keep-last-article} is non-@code{nil}, Gnus will never
-expire the final article in a mail newsgroup.  This is to make life
-easier for procmail users.
-
-@vindex gnus-total-expirable-newsgroups
-By the way: That line up there, about Gnus never expiring non-expirable
-articles, is a lie.  If you put @code{total-expire} in the group
-parameters, articles will not be marked as expirable, but all read
-articles will be put through the expiry process.  Use with extreme
-caution.  Even more dangerous is the
-@code{gnus-total-expirable-newsgroups} variable.  All groups that match
-this regexp will have all read articles put through the expiry process,
-which means that @emph{all} old mail articles in the groups in question
-will be deleted after a while.  Use with extreme caution, and don't come
-crying to me when you discover that the regexp you used matched the
-wrong group and all your important mail has disappeared.  Be a
-@emph{man}!  Or a @emph{woman}!  Whatever you feel more comfortable
-with!  So there!
-
-Most people make most of their mail groups total-expirable, though.
-
-@vindex gnus-inhibit-user-auto-expire
-If @code{gnus-inhibit-user-auto-expire} is non-@code{nil}, user marking
-commands will not mark an article as expirable, even if the group has
-auto-expire turned on.

-@node Washing Mail
-@subsection Washing Mail
-@cindex mail washing
-@cindex list server brain damage
-@cindex incoming mail treatment
-
-Mailers and list servers are notorious for doing all sorts of really,
-really stupid things with mail.  ``Hey, RFC822 doesn't explicitly
-prohibit us from adding the string @code{wE aRe ElItE!!!!!1!!} to the
-end of all lines passing through our server, so let's do that!!!!1!''
-Yes, but RFC822 wasn't designed to be read by morons.  Things that were
-considered to be self-evident were not discussed.  So.  Here we are.
-
-Case in point:  The German version of Microsoft Exchange adds @samp{AW:
-} to the subjects of replies instead of @samp{Re: }.  I could pretend to
-be shocked and dismayed by this, but I haven't got the energy.  It is to
-laugh.
-
-Gnus provides a plethora of functions for washing articles while
-displaying them, but it might be nicer to do the filtering before
-storing the mail to disc.  For that purpose, we have three hooks and
-various functions that can be put in these hooks.
-
-@table @code
-@item nnmail-prepare-incoming-hook
-@vindex nnmail-prepare-incoming-hook
-This hook is called before doing anything with the mail and is meant for
-grand, sweeping gestures.  It is called in a buffer that contains all
-the new, incoming mail.  Functions to be used include:
-
-@table @code
-@item nnheader-ms-strip-cr
-@findex nnheader-ms-strip-cr
-Remove trailing carriage returns from each line.  This is default on
-Emacs running on MS machines.
-
-@end table
-
-@item nnmail-prepare-incoming-header-hook
-@vindex nnmail-prepare-incoming-header-hook
-This hook is called narrowed to each header.  It can be used when
-cleaning up the headers.  Functions that can be used include:
-
-@table @code
-@item nnmail-remove-leading-whitespace
-@findex nnmail-remove-leading-whitespace
-Clear leading white space that ``helpful'' listservs have added to the
-headers to make them look nice.  Aaah.
-
-@item nnmail-remove-list-identifiers
-@findex nnmail-remove-list-identifiers
-Some list servers add an identifier---for example, @samp{(idm)}---to the
-beginning of all @code{Subject} headers.  I'm sure that's nice for
-people who use stone age mail readers.  This function will remove
-strings that match the @code{nnmail-list-identifiers} regexp, which can
-also be a list of regexp.
-
-For instance, if you want to remove the @samp{(idm)} and the
-@samp{nagnagnag} identifiers:
-
-@lisp
-(setq nnmail-list-identifiers
-      '("(idm)" "nagnagnag"))
-@end lisp
-
-This can also be done non-destructively with
-@code{gnus-list-identifiers}, @xref{Article Hiding}.
-
-@item nnmail-remove-tabs
-@findex nnmail-remove-tabs
-Translate all @samp{TAB} characters into @samp{SPACE} characters.
-
-@item nnmail-fix-eudora-headers
-@findex nnmail-fix-eudora-headers
-@cindex Eudora
-Eudora produces broken @code{References} headers, but OK
-@code{In-Reply-To} headers.  This function will get rid of the
-@code{References} headers.
-
-@end table
-
-@item nnmail-prepare-incoming-message-hook
-@vindex nnmail-prepare-incoming-message-hook
-This hook is called narrowed to each message.  Functions to be used

-@node Duplicates
-@subsection Duplicates
-
-@vindex nnmail-treat-duplicates
-@vindex nnmail-message-id-cache-length
-@vindex nnmail-message-id-cache-file
-@cindex duplicate mails
-If you are a member of a couple of mailing lists, you will sometimes
-receive two copies of the same mail.  This can be quite annoying, so
-@code{nnmail} checks for and treats any duplicates it might find.  To do
-this, it keeps a cache of old @code{Message-ID}s---
-@code{nnmail-message-id-cache-file}, which is @file{~/.nnmail-cache} by
-default.  The approximate maximum number of @code{Message-ID}s stored
-there is controlled by the @code{nnmail-message-id-cache-length}
-variable, which is 1000 by default. (So 1000 @code{Message-ID}s will be
-stored.) If all this sounds scary to you, you can set
-@code{nnmail-treat-duplicates} to @code{warn} (which is what it is by
-default), and @code{nnmail} won't delete duplicate mails.  Instead it
-will insert a warning into the head of the mail saying that it thinks
-that this is a duplicate of a different message.
-
-This variable can also be a function.  If that's the case, the function
-will be called from a buffer narrowed to the message in question with
-the @code{Message-ID} as a parameter.  The function must return either
-@code{nil}, @code{warn}, or @code{delete}.
-
-You can turn this feature off completely by setting the variable to
-@code{nil}.
-
-If you want all the duplicate mails to be put into a special
-@dfn{duplicates} group, you could do that using the normal mail split
-methods:
-
-@lisp
-(setq nnmail-split-fancy
-      '(| ;; Messages duplicates go to a separate group.
-          ("gnus-warning" "duplication of message" "duplicate")
-          ;; Message from daemons, postmaster, and the like to another.
-          (any mail "mail.misc")
-          ;; Other rules.
-          [ ... ] ))
-@end lisp
-
-Or something like:
-@lisp
-(setq nnmail-split-methods
-      '(("duplicates" "^Gnus-Warning:")
-        ;; Other rules.
-        [...]))
-@end lisp
-
-Here's a neat feature: If you know that the recipient reads her mail
-with Gnus, and that she has @code{nnmail-treat-duplicates} set to
-@code{delete}, you can send her as many insults as you like, just by
-using a @code{Message-ID} of a mail that you know that she's already
-received.  Think of all the fun!  She'll never see any of it!  Whee!

-file you have stashed away with @code{nnbabyl}.  All backends have
-variables called backend-@code{get-new-mail}.  If you want to disable
-the @code{nnbabyl} mail reading, you edit the virtual server for the
-group to have a setting where @code{nnbabyl-get-new-mail} to @code{nil}.

-If you use this backend, Gnus will split all incoming mail into files,

-
-You do not have to create any directories beforehand; Gnus will take
-care of all that.
-
-If you have a strict limit as to how many files you are allowed to store
-in your account, you should not use this backend.  As each mail gets its
-own file, you might very well occupy thousands of inodes within a few
-weeks.  If this is no problem for you, and it isn't a problem for you
-having your friendly systems administrator walking around, madly,
-shouting ``Who is eating all my inodes?! Who? Who!?!'', then you should

-to trudge through a big mbox file just to read your new mail.
-
-@code{nnml} is probably the slowest backend when it comes to article

-@node Comparing Mail Backends
-@subsubsection Comparing Mail Backends
-
-First, just for terminology, the @dfn{backend} is the common word for a
-low-level access method---a transport, if you will, by which something
-is acquired.  The sense is that one's mail has to come from somewhere,
-and so selection of a suitable backend is required in order to get that
-mail within spitting distance of Gnus.
-
-The same concept exists for Usenet itself: Though access to articles is
-typically done by NNTP these days, once upon a midnight dreary, everyone
-in the world got at Usenet by running a reader on the machine where the
-articles lay (the machine which today we call an NNTP server), and
-access was by the reader stepping into the articles' directory spool
-area directly.  One can still select between either the @code{nntp} or
-@code{nnspool} backends, to select between these methods, if one happens
-actually to live on the server (or can see its spool directly, anyway,
-via NFS).
-
-The goal in selecting a mail backend is to pick one which
-simultaneously represents a suitable way of dealing with the original
-format plus leaving mail in a form that is convenient to use in the
-future.  Here are some high and low points on each:
-
-@table @code
-@item nnmbox
-
-UNIX systems have historically had a single, very common, and well-
-defined format.  All messages arrive in a single @dfn{spool file}, and
-they are delineated by a line whose regular expression matches
-@samp{^From_}.  (My notational use of @samp{_} is to indicate a space,
-to make it clear in this instance that this is not the RFC-specified
-@samp{From:} header.)  Because Emacs and therefore Gnus emanate
-historically from the Unix environment, it is simplest if one does not
-mess a great deal with the original mailbox format, so if one chooses
-this backend, Gnus' primary activity in getting mail from the real spool
-area to Gnus' preferred directory is simply to copy it, with no
-(appreciable) format change in the process.  It is the ``dumbest'' way
-to move mail into availability in the Gnus environment.  This makes it
-fast to move into place, but slow to parse, when Gnus has to look at
-what's where.
-
-@item nnbabyl
-
-Once upon a time, there was the DEC-10 and DEC-20, running operating
-systems called TOPS and related things, and the usual (only?) mail
-reading environment was a thing called Babyl.  I don't know what format
-was used for mail landing on the system, but Babyl had its own internal
-format to which mail was converted, primarily involving creating a
-spool-file-like entity with a scheme for inserting Babyl-specific
-headers and status bits above the top of each message in the file.
-RMAIL was Emacs' first mail reader, it was written by Richard Stallman,
-and Stallman came out of that TOPS/Babyl environment, so he wrote RMAIL
-to understand the mail files folks already had in existence.  Gnus (and
-VM, for that matter) continue to support this format because it's
-perceived as having some good qualities in those mailer-specific
-headers/status bits stuff.  RMAIL itself still exists as well, of
-course, and is still maintained by Stallman.
-
-Both of the above forms leave your mail in a single file on your
-filesystem, and they must parse that entire file each time you take a
-look at your mail.
-
-@item nnml
-
-@code{nnml} is the backend which smells the most as though you were
-actually operating with an @code{nnspool}-accessed Usenet system.  (In
-fact, I believe @code{nnml} actually derived from @code{nnspool} code,
-lo these years ago.)  One's mail is taken from the original spool file,
-and is then cut up into individual message files, 1:1.  It maintains a
-Usenet-style active file (analogous to what one finds in an INN- or
-CNews-based news system in (for instance) @file{/var/lib/news/active},
-or what is returned via the @samp{NNTP LIST} verb) and also creates
-@dfn{overview} files for efficient group entry, as has been defined for
-@sc{nntp} servers for some years now.  It is slower in mail-splitting,
-due to the creation of lots of files, updates to the @code{nnml} active
-file, and additions to overview files on a per-message basis, but it is
-extremely fast on access because of what amounts to the indexing support
-provided by the active file and overviews.
-
-@code{nnml} costs @dfn{inodes} in a big way; that is, it soaks up the
-resource which defines available places in the filesystem to put new
-files.  Sysadmins take a dim view of heavy inode occupation within
-tight, shared filesystems.  But if you live on a personal machine where
-the filesystem is your own and space is not at a premium, @code{nnml}
-wins big.
-
-It is also problematic using this backend if you are living in a
-FAT16-based Windows world, since much space will be wasted on all these
-tiny files.
-
-@item nnmh
-
-The Rand MH mail-reading system has been around UNIX systems for a very
-long time; it operates by splitting one's spool file of messages into
-individual files, but with little or no indexing support -- @code{nnmh}
-is considered to be semantically equivalent to ``@code{nnml} without
-active file or overviews''.  This is arguably the worst choice, because
-one gets the slowness of individual file creation married to the
-slowness of access parsing when learning what's new in one's groups.
-
-@item nnfolder
-
-Basically the effect of @code{nnfolder} is @code{nnmbox} (the first
-method described above) on a per-group basis.  That is, @code{nnmbox}
-itself puts *all* one's mail in one file; @code{nnfolder} provides a
-little bit of optimization to this so that each of one's mail groups has
-a Unix mail box file.  It's faster than @code{nnmbox} because each group
-can be parsed separately, and still provides the simple Unix mail box
-format requiring minimal effort in moving the mail around.  In addition, 
-it maintains an ``active'' file making it much faster for Gnus to figure 
-out how many messages there are in each separate group.
-
-If you have groups that are expected to have a massive amount of
-messages, @code{nnfolder} is not the best choice, but if you receive
-only a moderate amount of mail, @code{nnfolder} is probably the most
-friendly mail backend all over.

-Web-based discussion forums are getting more and more popular.  On many
-subjects, the web-based forums have become the most important forums,
-eclipsing the importance of mailing lists and news groups.  The reason
-is easy to understand---they are friendly to new users; you just point
-and click, and there's the discussion.  With mailing lists, you have to
-go through a cumbersome subscription procedure, and most people don't
-even know what a news group is.
-
-The problem with this scenario is that web browsers are not very good at 
-being newsreaders.  They do not keep track of what articles you've read; 
-they do not allow you to score on subjects you're interested in; they do 
-not allow off-line browsing; they require you to click around and drive
-you mad in the end.
-
-So---if web browsers suck at reading discussion forums, why not use Gnus 
-to do it instead?
-
-Gnus has been getting a bit of a collection of backends for providing
-interfaces to these sources.
-
-@menu
-* Web Searches::          Creating groups from articles that match a string.
-* Slashdot::              Reading the Slashdot comments.
-* Ultimate::              The Ultimate Bulletin Board systems.
-@end menu
-
-The main caveat with all these web sources is that they probably won't
-work for a very long time.  Gleaning information from the @sc{html} data 
-is guesswork at best, and when the layout is altered, the Gnus backend
-will fail.  If you have reasonably new versions of these backends,
-though, you should be ok.
-
-One thing all these Web methods have in common is that the Web sources
-are often down, unavailable or just plain too slow to be fun.  In those
-cases, it makes a lot of sense to let the Gnus Agent (@pxref{Gnus
-Unplugged}) handle downloading articles, and then you can read them at
-leisure from your local disk.  No more World Wide Wait for you.

-It's, like, too neat to search the Usenet for articles that match a
-string, but it, like, totally @emph{sucks}, like, totally, to use one of
-those, like, Web browsers, and you, like, have to, rilly, like, look at
-the commercials, so, like, with Gnus you can do @emph{rad}, rilly,
-searches without having to use a browser.
-
-The @code{nnweb} backend allows an easy interface to the mighty search
-engine.  You create an @code{nnweb} group, enter a search pattern, and
-then enter the group and read the articles like you would any normal
-group.  The @kbd{G w} command in the group buffer (@pxref{Foreign
-Groups}) will do this in an easy-to-use fashion.
-
-@code{nnweb} groups don't really lend themselves to being solid
-groups---they have a very fleeting idea of article numbers.  In fact,
-each time you enter an @code{nnweb} group (not even changing the search
-pattern), you are likely to get the articles ordered in a different
-manner.  Not even using duplicate suppression (@pxref{Duplicate
-Suppression}) will help, since @code{nnweb} doesn't even know the
-@code{Message-ID} of the articles before reading them using some search
-engines (DejaNews, for instance).  The only possible way to keep track
-of which articles you've read is by scoring on the @code{Date}
-header---mark all articles posted before the last date you read the
-group as read.
-
-If the search engine changes its output substantially, @code{nnweb}
-won't be able to parse it and will fail.  One could hardly fault the Web
-providers if they were to do this---their @emph{raison d'être} is to
-make money off of advertisements, not to provide services to the
-community.  Since @code{nnweb} washes the ads off all the articles, one
-might think that the providers might be somewhat miffed.  We'll see.

-You must have the @code{url} and @code{w3} package installed to be able

-
-@lisp

-
-When following up to @code{nnslashdot} comments (or posting new
-comments), some light @sc{html}izations will be performed.  In
-particular, text quoted with @samp{> } will be quoted with
-@code{blockquote} instead, and signatures will have @code{br} added to
-the end of each line.  Other than that, you can just write @sc{html}

-Whether @code{nnslashdot} should display threaded groups or not.  The

-@cindex directory groups
-
-If you have a directory that has lots of articles in separate files in

-names, of course.
-
-This might be an opportune moment to mention @code{ange-ftp} (and its
-successor @code{efs}), that most wonderful of all wonderful Emacs
-packages.  When I wrote @code{nndir}, I didn't think much about it---a
-backend to read directories.  Big deal.
-
-@code{ange-ftp} changes that picture dramatically.  For instance, if you
-enter the @code{ange-ftp} file name
-@file{/ftp.hpc.uh.edu:/pub/emacs/ding-list/} as the directory name,
-@code{ange-ftp} or @code{efs} will actually allow you to read this
-directory over at @samp{sina} as a newsgroup.  Distributed news ahoy!
-
-@code{nndir} will use @sc{nov} files if they are present.
-
-@code{nndir} is a ``read-only'' backend---you can't delete or expire
-articles with this method.  You can use @code{nnmh} or @code{nnml} for
-whatever you use @code{nndir} for, so you could switch to any of those
-methods if you feel the need to have a non-read-only @code{nndir}.
-
-
-@node Anything Groups
-@subsection Anything Groups
-@cindex nneething
-
-From the @code{nndir} backend (which reads a single spool-like
-directory), it's just a hop and a skip to @code{nneething}, which
-pretends that any arbitrary directory is a newsgroup.  Strange, but
-true.
-
-When @code{nneething} is presented with a directory, it will scan this
-directory and assign article numbers to each file.  When you enter such
-a group, @code{nneething} must create ``headers'' that Gnus can use.
-After all, Gnus is a newsreader, in case you're
-forgetting. @code{nneething} does this in a two-step process.  First, it
-snoops each file in question.  If the file looks like an article (i.e.,
-the first few lines look like headers), it will use this as the head.
-If this is just some arbitrary file without a head (e.g. a C source
-file), @code{nneething} will cobble up a header out of thin air.  It
-will use file ownership, name and date and do whatever it can with these
-elements.
-
-All this should happen automatically for you, and you will be presented
-with something that looks very much like a newsgroup.  Totally like a
-newsgroup, to be precise.  If you select an article, it will be displayed
-in the article buffer, just as usual.
-
-If you select a line that represents a directory, Gnus will pop you into
-a new summary buffer for this @code{nneething} group.  And so on.  You can
-traverse the entire disk this way, if you feel like, but remember that
-Gnus is not dired, really, and does not intend to be, either.
-
-There are two overall modes to this action---ephemeral or solid.  When
-doing the ephemeral thing (i.e., @kbd{G D} from the group buffer), Gnus
-will not store information on what files you have read, and what files
-are new, and so on.  If you create a solid @code{nneething} group the
-normal way with @kbd{G m}, Gnus will store a mapping table between
-article numbers and file names, and you can treat this group like any
-other groups.  When you activate a solid @code{nneething} group, you will
-be told how many unread articles it contains, etc., etc.
-
-Some variables:
-
-@table @code
-@item nneething-map-file-directory
-@vindex nneething-map-file-directory
-All the mapping files for solid @code{nneething} groups will be stored
-in this directory, which defaults to @file{~/.nneething/}.
-
-@item nneething-exclude-files
-@vindex nneething-exclude-files
-All files that match this regexp will be ignored.  Nice to use to exclude
-auto-save files and the like, which is what it does by default.
-
-@item nneething-include-files
-@vindex nneething-include-files
-Regexp saying what files to include in the group.  If this variable is
-non-@code{nil}, only files matching this regexp will be included.

-@subsubsection Document Server Internals
-
-Adding new document types to be recognized by @code{nndoc} isn't
-difficult.  You just have to whip up a definition of what the document
-looks like, write a predicate function to recognize that document type,
-and then hook into @code{nndoc}.
-
-First, here's an example document type definition:
-
-@example
-(mmdf
- (article-begin .  "^\^A\^A\^A\^A\n")
- (body-end .  "^\^A\^A\^A\^A\n"))
-@end example
-
-The definition is simply a unique @dfn{name} followed by a series of
-regexp pseudo-variable settings.  Below are the possible
-variables---don't be daunted by the number of variables; most document
-types can be defined with very few settings:
-
-@table @code
-@item first-article
-If present, @code{nndoc} will skip past all text until it finds
-something that match this regexp.  All text before this will be
-totally ignored.
-
-@item article-begin
-This setting has to be present in all document type definitions.  It
-says what the beginning of each article looks like.
-
-@item head-begin-function
-If present, this should be a function that moves point to the head of
-the article.
-
-@item nndoc-head-begin
-If present, this should be a regexp that matches the head of the
-article.
-
-@item nndoc-head-end
-This should match the end of the head of the article.  It defaults to
-@samp{^$}---the empty line.
-
-@item body-begin-function
-If present, this function should move point to the beginning of the body
-of the article.
-
-@item body-begin
-This should match the beginning of the body of the article.  It defaults
-to @samp{^\n}.
-
-@item body-end-function
-If present, this function should move point to the end of the body of
-the article.
-
-@item body-end
-If present, this should match the end of the body of the article.
-
-@item file-end
-If present, this should match the end of the file.  All text after this
-regexp will be totally ignored.
-
-@end table
-
-So, using these variables @code{nndoc} is able to dissect a document
-file into a series of articles, each with a head and a body.  However, a
-few more variables are needed since not all document types are all that
-news-like---variables needed to transform the head or the body into
-something that's palatable for Gnus:
-
-@table @code
-@item prepare-body-function
-If present, this function will be called when requesting an article.  It
-will be called with point at the start of the body, and is useful if the
-document has encoded some parts of its contents.
-
-@item article-transform-function
-If present, this function is called when requesting an article.  It's
-meant to be used for more wide-ranging transformation of both head and
-body of the article.
-
-@item generate-head-function
-If present, this function is called to generate a head that Gnus can
-understand.  It is called with the article number as a parameter, and is
-expected to generate a nice head for the article in question.  It is
-called when requesting the headers of all articles.
-
-@end table
-
-Let's look at the most complicated example I can come up with---standard
-digests:
-
-@example
-(standard-digest
- (first-article . ,(concat "^" (make-string 70 ?-) "\n\n+"))
- (article-begin . ,(concat "\n\n" (make-string 30 ?-) "\n\n+"))
- (prepare-body-function . nndoc-unquote-dashes)
- (body-end-function . nndoc-digest-body-end)
- (head-end . "^ ?$")
- (body-begin . "^ ?\n")
- (file-end . "^End of .*digest.*[0-9].*\n\\*\\*\\|^End of.*Digest *$")
- (subtype digest guess))
-@end example
-
-We see that all text before a 70-width line of dashes is ignored; all
-text after a line that starts with that @samp{^End of} is also ignored;
-each article begins with a 30-width line of dashes; the line separating
-the head from the body may contain a single space; and that the body is
-run through @code{nndoc-unquote-dashes} before being delivered.
-
-To hook your own document definition into @code{nndoc}, use the
-@code{nndoc-add-type} function.  It takes two parameters---the first is
-the definition itself and the second (optional) parameter says where in
-the document type definition alist to put this definition.  The alist is
-traversed sequentially, and @code{nndoc-TYPE-type-p} is called for a given type @code{TYPE}.  So @code{nndoc-mmdf-type-p} is called to see whether a document
-is of @code{mmdf} type, and so on.  These type predicates should return
-@code{nil} if the document is not of the correct type; @code{t} if it is
-of the correct type; and a number if the document might be of the
-correct type.  A high number means high probability; a low number means
-low probability with @samp{0} being the lowest valid number.

-@cindex offline
-
-In the PC world people often talk about ``offline'' newsreaders.  These
-are thingies that are combined reader/news transport monstrosities.
-With built-in modem programs.  Yecchh!
-
-Of course, us Unix Weenie types of human beans use things like
-@code{uucp} and, like, @code{nntpd} and set up proper news and mail
-transport things like Ghod intended.  And then we just use normal
-newsreaders.
-
-However, it can sometimes be convenient to do something that's a bit
-easier on the brain if you have a very slow modem, and you're not really
-that interested in doing things properly.
-
-A file format called @sc{soup} has been developed for transporting news
-and mail from servers to home machines and back again.  It can be a bit
-fiddly.
-
-First some terminology:
-
-@table @dfn
-
-@item server
-This is the machine that is connected to the outside world and where you
-get news and/or mail from.
-
-@item home machine
-This is the machine that you want to do the actual reading and responding
-on.  It is typically not connected to the rest of the world in any way.
-
-@item packet
-Something that contains messages and/or commands.  There are two kinds
-of packets:
-
-@table @dfn
-@item message packets
-These are packets made at the server, and typically contain lots of
-messages for you to read.  These are called @file{SoupoutX.tgz} by
-default, where @var{x} is a number.
-
-@item response packets
-These are packets made at the home machine, and typically contains
-replies that you've written.  These are called @file{SoupinX.tgz} by
-default, where @var{x} is a number.
-
-@end table
-
-@end table
-
-
-@enumerate
-
-@item
-You log in on the server and create a @sc{soup} packet.  You can either
-use a dedicated @sc{soup} thingie (like the @code{awk} program), or you
-can use Gnus to create the packet with its @sc{soup} commands (@kbd{O
-s} and/or @kbd{G s b}; and then @kbd{G s p}) (@pxref{SOUP Commands}).
-
-@item
-You transfer the packet home.  Rail, boat, car or modem will do fine.
-
-@item
-You put the packet in your home directory.
-
-@item
-You fire up Gnus on your home machine using the @code{nnsoup} backend as
-the native or secondary server.
-
-@item
-You read articles and mail and answer and followup to the things you
-want (@pxref{SOUP Replies}).
-
-@item
-You do the @kbd{G s r} command to pack these replies into a @sc{soup}
-packet.
-
-@item
-You transfer this packet to the server.
-
-@item
-You use Gnus to mail this packet out with the @kbd{G s s} command.
-
-@item
-You then repeat until you die.
-
-@end enumerate
-
-So you basically have a bipartite system---you use @code{nnsoup} for
-reading and Gnus for packing/sending these @sc{soup} packets.

-The @code{nngateway} backend provides the interface.
-
-Note that you can't read anything from this backend---it can only be
-used to post with.
-
-Server variables:
-
-@table @code
-@item nngateway-address
-@vindex nngateway-address
-This is the address of the mail-to-news gateway.
-
-@item nngateway-header-transformation
-@vindex nngateway-header-transformation
-News headers often have to be transformed in some odd way or other
-for the mail-to-news gateway to accept it.  This variable says what
-transformation should be called, and defaults to
-@code{nngateway-simple-header-transformation}.  The function is called
-narrowed to the headers to be transformed and with one parameter---the
-gateway address.
-
-This default function just inserts a new @code{To} header based on the
-@code{Newsgroups} header and the gateway address.
-For instance, an article with this @code{Newsgroups} header:
-
-@example
-Newsgroups: alt.religion.emacs
-@end example
-
-will get this @code{From} header inserted:
-
-@example
-To: alt-religion-emacs@@GATEWAY
-@end example
-
-The following pre-defined functions exist:
-
-@findex nngateway-simple-header-transformation

-@item nngateway-simple-header-transformation
-Creates a @code{To} header that looks like
-@var{newsgroup}@@@code{nngateway-address}.

-@findex nngateway-mail2news-header-transformation
-
-@item nngateway-mail2news-header-transformation
-Creates a @code{To} header that looks like

-Port on server to contact. Defaults to port 143, or 993 for SSL.
-
-@item nnimap-list-pattern
-@vindex nnimap-list-pattern
-String or list of strings of mailboxes to limit available groups
-to. This is used when the server has very many mailboxes and you're only
-interested in a few -- some servers export your home directory via IMAP,
-you'll probably want to limit the mailboxes to those in @file{~/Mail/*}
-then.
-
-The string can also be a cons of REFERENCE and the string as above, what
-REFERENCE is used for is server specific, but on the University of
-Washington server it's a directory that will be concatenated with the

-Splitting is something Gnus users has loved and used for years, and now
-the rest of the world is catching up. Yeah, dream on, not many IMAP
-server has server side splitting and those that have splitting seem to
-use some non-standard protocol. This means that IMAP support for Gnus
-has to do it's own splitting.
-
-And it does.
-
-There are three variables of interest:
-
-@table @code
-
-@item nnimap-split-crosspost
-@cindex splitting, crosspost
-@cindex crosspost
-@vindex nnimap-split-crosspost
-
-If non-nil, do crossposting if several split methods match the mail. If
-nil, the first match in @code{nnimap-split-rule} found will be used.
-
-Nnmail equivalent: @code{nnmail-crosspost}.
-
-@item nnimap-split-inbox
-@cindex splitting, inbox
-@cindex inbox
-@vindex nnimap-split-inbox
-
-A string or a list of strings that gives the name(s) of IMAP mailboxes
-to split from. Defaults to nil, which means that splitting is disabled!
-
-@lisp
-(setq nnimap-split-inbox '("INBOX" ("~/friend/Mail" . "lists/*") "lists.imap"))
-@end lisp
-
-No nnmail equivalent.
-
-@item nnimap-split-rule
-@cindex Splitting, rules
-@vindex nnimap-split-rule
-
-New mail found in @code{nnimap-split-inbox} will be split according to
-this variable.
-
-This variable contains a list of lists, where the first element in the
-sublist gives the name of the IMAP mailbox to move articles matching the
-regexp in the second element in the sublist. Got that? Neither did I, we
-need examples.
-
-@lisp
-(setq nnimap-split-rule
-        '(("INBOX.nnimap"        "^Sender: owner-nnimap@@vic20.globalcom.se")
-          ("INBOX.junk"          "^Subject:.*MAKE MONEY")
-          ("INBOX.private"       "")))
-@end lisp
-
-This will put all articles from the nnimap mailing list into mailbox
-INBOX.nnimap, all articles containing MAKE MONEY in the Subject: line
-into INBOX.spam and everything else in INBOX.private.
-
-The first string may contain `\\1' forms, like the ones used by
-replace-match to insert sub-expressions from the matched text. For
-instance:
-
-@lisp
-("INBOX.lists.\\1"     "^Sender: owner-\\([a-z-]+\\)@@")
-@end lisp
-
-The second element can also be a function. In that case, it will be
-called with the first element of the rule as the argument, in a buffer
-containing the headers of the article. It should return a non-nil value
-if it thinks that the mail belongs in that group.
-
-Nnmail users might recollect that the last regexp had to be empty to
-match all articles (like in the example above). This is not required in
-nnimap. Articles not matching any of the regexps will not be moved out
-of your inbox. (This might might affect performance if you keep lots of
-unread articles in your inbox, since the splitting code would go over
-them every time you fetch new mail.)
-
-These rules are processed from the beginning of the alist toward the
-end. The first rule to make a match will "win", unless you have
-crossposting enabled. In that case, all matching rules will "win".
-
-The splitting code tries to create mailboxes if it need too.
-
-Nnmail equivalent: @code{nnmail-split-methods}.

-@cindex nnvirtual
-@cindex virtual groups
-@cindex merging groups
-
-An @dfn{nnvirtual group} is really nothing more than a collection of
-other groups.
-
-For instance, if you are tired of reading many small groups, you can
-put them all in one big group, and then grow tired of reading one
-big, unwieldy group.  The joys of computing!
-
-You specify @code{nnvirtual} as the method.  The address should be a
-regexp to match component groups.
-
-All marks in the virtual group will stick to the articles in the
-component groups.  So if you tick an article in a virtual group, the
-article will also be ticked in the component group from whence it came.
-(And vice versa---marks from the component groups will also be shown in
-the virtual group.)
-
-Here's an example @code{nnvirtual} method that collects all Andrea Dworkin
-newsgroups into one, big, happy newsgroup:
-
-@lisp
-(nnvirtual "^alt\\.fan\\.andrea-dworkin$\\|^rec\\.dworkin.*")
-@end lisp
-
-The component groups can be native or foreign; everything should work
-smoothly, but if your computer explodes, it was probably my fault.
-
-Collecting the same group from several servers might actually be a good
-idea if users have set the Distribution header to limit distribution.
-If you would like to read @samp{soc.motss} both from a server in Japan
-and a server in Norway, you could use the following as the group regexp:
-
-@example
-"^nntp\\+server\\.jp:soc\\.motss$\\|^nntp\\+server\\.no:soc\\.motss$"
-@end example
-
-(Remember, though, that if you're creating the group with @kbd{G m}, you
-shouldn't double the backslashes, and you should leave off the quote
-characters at the beginning and the end of the string.)
-
-This should work kinda smoothly---all articles from both groups should
-end up in this one, and there should be no duplicates.  Threading (and
-the rest) will still work as usual, but there might be problems with the
-sequence of articles.  Sorting on date might be an option here
-(@pxref{Selecting a Group}).
-
-One limitation, however---all groups included in a virtual
-group have to be alive (i.e., subscribed or unsubscribed).  Killed or
-zombie groups can't be component groups for @code{nnvirtual} groups.
-
-@vindex nnvirtual-always-rescan
-If the @code{nnvirtual-always-rescan} is non-@code{nil},
-@code{nnvirtual} will always scan groups for unread articles when
-entering a virtual group.  If this variable is @code{nil} (which is the
-default) and you read articles in a component group after the virtual
-group has been activated, the read articles from the component group
-will show up when you enter the virtual group.  You'll also see this
-effect if you have two virtual groups that have a component group in
-common.  If that's the case, you should set this variable to @code{t}.
-Or you can just tap @code{M-g} on the virtual group every time before
-you enter it---it'll have much the same effect.
-
-@code{nnvirtual} can have both mail and news groups as component groups.
-When responding to articles in @code{nnvirtual} groups, @code{nnvirtual}
-has to ask the backend of the component group the article comes from
-whether it is a news or mail backend.  However, when you do a @kbd{^},
-there is typically no sure way for the component backend to know this,
-and in that case @code{nnvirtual} tells Gnus that the article came from a
-not-news backend.  (Just to be on the safe side.)
-
-@kbd{C-c C-t} in the message buffer will insert the @code{Newsgroups}
-line from the article you respond to in these cases.

-@node Kibozed Groups
-@subsection Kibozed Groups
-@cindex nnkiboze
-@cindex kibozing
-
-@dfn{Kibozing} is defined by @sc{oed} as ``grepping through (parts of)
-the news feed''.  @code{nnkiboze} is a backend that will do this for
-you.  Oh joy!  Now you can grind any @sc{nntp} server down to a halt
-with useless requests!  Oh happiness!
-
-@kindex G k (Group)
-To create a kibozed group, use the @kbd{G k} command in the group
-buffer.
-
-The address field of the @code{nnkiboze} method is, as with
-@code{nnvirtual}, a regexp to match groups to be ``included'' in the
-@code{nnkiboze} group.  That's where most similarities between @code{nnkiboze}
-and @code{nnvirtual} end.
-
-In addition to this regexp detailing component groups, an @code{nnkiboze} group
-must have a score file to say what articles are to be included in
-the group (@pxref{Scoring}).
-
-@kindex M-x nnkiboze-generate-groups
-@findex nnkiboze-generate-groups
-You must run @kbd{M-x nnkiboze-generate-groups} after creating the
-@code{nnkiboze} groups you want to have.  This command will take time.  Lots of
-time.  Oodles and oodles of time.  Gnus has to fetch the headers from
-all the articles in all the component groups and run them through the
-scoring process to determine if there are any articles in the groups
-that are to be part of the @code{nnkiboze} groups.
-
-Please limit the number of component groups by using restrictive
-regexps.  Otherwise your sysadmin may become annoyed with you, and the
-@sc{nntp} site may throw you off and never let you back in again.
-Stranger things have happened.
-
-@code{nnkiboze} component groups do not have to be alive---they can be dead,
-and they can be foreign.  No restrictions.
-
-@vindex nnkiboze-directory
-The generation of an @code{nnkiboze} group means writing two files in
-@code{nnkiboze-directory}, which is @file{~/News/} by default.  One
-contains the @sc{nov} header lines for all the articles in the group,
-and the other is an additional @file{.newsrc} file to store information
-on what groups have been searched through to find component articles.
-
-Articles marked as read in the @code{nnkiboze} group will have
-their @sc{nov} lines removed from the @sc{nov} file.

-In olden times (ca. February '88), people used to run their newsreaders
-on big machines with permanent connections to the net.  News transport
-was dealt with by news servers, and all the newsreaders had to do was to
-read news.  Believe it or not.
-
-Nowadays most people read news and mail at home, and use some sort of
-modem to connect to the net.  To avoid running up huge phone bills, it
-would be nice to have a way to slurp down all the news and mail, hang up
-the phone, read for several hours, and then upload any responses you
-have to make.  And then you repeat the procedure.
-
-Of course, you can use news servers for doing this as well.  I've used
-@code{inn} together with @code{slurp}, @code{pop} and @code{sendmail}
-for some years, but doing that's a bore.  Moving the news server
-functionality up to the newsreader makes sense if you're the only person
-reading news on a machine.
-
-Using Gnus as an ``offline'' newsreader is quite simple.

-@subsection Agent Basics
-
-First, let's get some terminology out of the way.
-
-The Gnus Agent is said to be @dfn{unplugged} when you have severed the
-connection to the net (and notified the Agent that this is the case).
-When the connection to the net is up again (and Gnus knows this), the
-Agent is @dfn{plugged}.
-
-The @dfn{local} machine is the one you're running on, and which isn't
-connected to the net continuously.
-
-@dfn{Downloading} means fetching things from the net to your local
-machine.  @dfn{Uploading} is doing the opposite.
-
-Let's take a typical Gnus session using the Agent.
-
-@itemize @bullet
-
-@item
-You start Gnus with @code{gnus-unplugged}.  This brings up the Gnus
-Agent in a disconnected state.  You can read all the news that you have
-already fetched while in this mode.
-
-@item
-You then decide to see whether any new news has arrived.  You connect
-your machine to the net (using PPP or whatever), and then hit @kbd{J j}
-to make Gnus become @dfn{plugged}.
-
-@item
-You can then read the new news immediately, or you can download the news
-onto your local machine.  If you want to do the latter, you press @kbd{J
-s} to fetch all the eligible articles in all the groups.  (To let Gnus
-know which articles you want to download, @pxref{Agent Categories}.)
-
-@item
-After fetching the articles, you press @kbd{J j} to make Gnus become
-unplugged again, and you shut down the PPP thing (or whatever).  And
-then you read the news offline.
-
-@item
-And then you go to step 2.
-@end itemize
-
-Here are some things you should do the first time (or so) that you use
-the Agent.
-
-@itemize @bullet
-
-@item
-Decide which servers should be covered by the Agent.  If you have a mail
-backend, it would probably be nonsensical to have it covered by the
-Agent.  Go to the server buffer (@kbd{^} in the group buffer) and press
-@kbd{J a} the server (or servers) that you wish to have covered by the
-Agent (@pxref{Server Agent Commands}).  This will typically be only the
-primary select method, which is listed on the bottom in the buffer.
-
-@item
-Decide on download policy.  @xref{Agent Categories}.
-
-@item
-Uhm... that's it.
-@end itemize
-
-
-@node Agent Categories
-@subsection Agent Categories
-
-One of the main reasons to integrate the news transport layer into the
-newsreader is to allow greater control over what articles to download.
-There's not much point in downloading huge amounts of articles, just to
-find out that you're not interested in reading any of them.  It's better
-to be somewhat more conservative in choosing what to download, and then
-mark the articles for downloading manually if it should turn out that
-you're interested in the articles anyway.
-
-The main way to control what is to be downloaded is to create a
-@dfn{category} and then assign some (or all) groups to this category.
-Groups that do not belong in any other category belong to the
-@code{default} category. Gnus has its own buffer for creating and
-managing categories.
-
-@menu
-* Category Syntax::       What a category looks like.
-* The Category Buffer::   A buffer for maintaining categories.
-* Category Variables::    Customize'r'Us.
-@end menu
-
-
-@node Category Syntax
-@subsubsection Category Syntax
-
-A category consists of two things.
-
-@enumerate
-@item
-A predicate which (generally) gives a rough outline of which articles
-are eligible for downloading; and
-
-@item
-a score rule which (generally) gives you a finer granularity when
-deciding what articles to download.  (Note that this @dfn{download
-score} is not necessarily related to normal scores.)
-@end enumerate
-
-A predicate in its simplest form can be a single predicate such as
-@code{true} or @code{false}. These two will download every available
-article or nothing respectively. In the case of these two special
-predicates an additional score rule is superfluous.
-
-Predicates of @code{high} or @code{low} download articles in respect of
-their scores in relationship to @code{gnus-agent-high-score} and
-@code{gnus-agent-low-score} as descibed below.
-
-To gain even finer control of what is to be regarded eligible for
-download a predicate can consist of a number of predicates with logical
-operators sprinkled in between.
-
-Perhaps some examples are in order.
-
-Here's a simple predicate.  (It's the default predicate, in fact, used
-for all groups that don't belong to any other category.)
-
-@lisp
-short
-@end lisp
-
-Quite simple, eh?  This predicate is true if and only if the article is
-short (for some value of ``short'').
-
-Here's a more complex predicate:
-
-@lisp
-(or high
-    (and
-     (not low)
-     (not long)))
-@end lisp
-
-This means that an article should be downloaded if it has a high score,
-or if the score is not low and the article is not long.  You get the
-drift.
-
-The available logical operators are @code{or}, @code{and} and
-@code{not}.  (If you prefer, you can use the more ``C''-ish operators
-@samp{|}, @code{&} and @code{!} instead.)
-
-The following predicates are pre-defined, but if none of these fit what
-you want to do, you can write your own.
-
-@table @code
-@item short
-True iff the article is shorter than @code{gnus-agent-short-article}
-lines; default 100.
-
-@item long
-True iff the article is longer than @code{gnus-agent-long-article}
-lines; default 200.
-
-@item low
-True iff the article has a download score less than
-@code{gnus-agent-low-score}; default 0.
-
-@item high
-True iff the article has a download score greater than
-@code{gnus-agent-high-score}; default 0.
-
-@item spam
-True iff the Gnus Agent guesses that the article is spam.  The
-heuristics may change over time, but at present it just computes a
-checksum and sees whether articles match.
-
-@item true
-Always true.
-
-@item false
-Always false.
-@end table
-
-If you want to create your own predicate function, here's what you have
-to know:  The functions are called with no parameters, but the
-@code{gnus-headers} and @code{gnus-score} dynamic variables are bound to
-useful values.
-
-For example, you could decide that you don't want to download articles
-that were posted more than a certain number of days ago (e.g. posted
-more than @code{gnus-agent-expire-days} ago) you might write a function
-something along the lines of the following:
-
-@lisp
-(defun my-article-old-p ()
-  "Say whether an article is old."
-  (< (time-to-days (date-to-time (mail-header-date gnus-headers)))
-     (- (time-to-days (current-time)) gnus-agent-expire-days)))
-@end lisp
-
-with the predicate then defined as:
-
-@lisp
-(not my-article-old-p)
-@end lisp
-
-or you could append your predicate to the predefined
-@code{gnus-category-predicate-alist} in your @file{~/.gnus.el} or
-wherever.  (Note: this would have to be at a point *after*
-@code{gnus-agent} has been loaded via @code{(gnus-agentize)})
-
-@lisp
-(defvar  gnus-category-predicate-alist
-  (append gnus-category-predicate-alist
-	 '((old . my-article-old-p))))
-@end lisp
-
-and simply specify your predicate as:
-
-@lisp
-(not old)
-@end lisp
-
-If/when using something like the above, be aware that there are many
-misconfigured systems/mailers out there and so an article's date is not
-always a reliable indication of when it was posted. Hell, some people
-just don't give a damm.
-
-
-The above predicates apply to *all* the groups which belong to the
-category. However, if you wish to have a specific predicate for an
-individual group within a category, or you're just too lazy to set up a
-new category, you can enter a group's individual predicate in it's group
-parameters like so:
-
-@lisp
-(agent-predicate . short)
-@end lisp
-
-This is the group parameter equivalent of the agent category
-default. Note that when specifying a single word predicate like this,
-the @code{agent-predicate} specification must be in dotted pair
-notation.
-
-The equivalent of the longer example from above would be:
-
-@lisp
-(agent-predicate or high (and (not low) (not long)))
-@end lisp
-
-The outer parenthesis required in the category specification are not
-entered here as, not being in dotted pair notation, the value of the
-predicate is assumed to be a list.
-
-
-Now, the syntax of the download score is the same as the syntax of
-normal score files, except that all elements that require actually
-seeing the article itself are verboten.  This means that only the
-following headers can be scored on: @code{Subject}, @code{From},
-@code{Date}, @code{Message-ID}, @code{References}, @code{Chars},
-@code{Lines}, and @code{Xref}.
-
-As with predicates, the specification of the @code{download score rule}
-to use in respect of a group can be in either the category definition if
-it's to be applicable to all groups in therein, or a group's parameters
-if it's to be specific to that group.
-
-In both of these places the @code{download score rule} can take one of
-three forms:
-
-@enumerate
-@item
-Score rule
-
-This has the same syntax as a normal gnus score file except only a
-subset of scoring keywords are available as mentioned above.
-
-example:
-
-@itemize @bullet
-@item
-Category specification
-
-@lisp
-(("from"
-       ("Lars Ingebrigtsen" 1000000 nil s))
-("lines"
-       (500 -100 nil <)))
-@end lisp
-
-@item
-Group Parameter specification
-
-@lisp
-(agent-score ("from"
-                   ("Lars Ingebrigtsen" 1000000 nil s))
-             ("lines"
-                   (500 -100 nil <)))
-@end lisp
-
-Again, note the omission of the outermost parenthesis here.
-@end itemize
-
-@item
-Agent score file
-
-These score files must *only* contain the permitted scoring keywords
-stated above.
-
-example:
-
-@itemize @bullet
-@item
-Category specification
-
-@lisp
-("~/News/agent.SCORE")
-@end lisp
-
-or perhaps
-
-@lisp
-("~/News/agent.SCORE" "~/News/agent.group.SCORE")
-@end lisp
-
-@item
-Group Parameter specification
-
-@lisp
-(agent-score "~/News/agent.SCORE")
-@end lisp
-
-Additional score files can be specified as above. Need I say anything
-about parenthesis.
-@end itemize
-
-@item
-Use @code{normal} score files
-
-If you dont want to maintain two sets of scoring rules for a group, and
-your desired @code{downloading} criteria for a group are the same as your
-@code{reading} criteria then you can tell the agent to refer to your
-@code{normal} score files when deciding what to download.
-
-These directives in either the category definition or a group's
-parameters will cause the agent to read in all the applicable score
-files for a group, *filtering out* those those sections that do not
-relate to one of the permitted subset of scoring keywords.

-@node Example Setup
-@subsection Example Setup
-
-If you don't want to read this manual, and you have a fairly standard
-setup, you may be able to use something like the following as your
-@file{.gnus.el} file to get started.
-
-@lisp
-;;; Define how Gnus is to fetch news.  We do this over NNTP
-;;; from your ISP's server.
-(setq gnus-select-method '(nntp "news.your-isp.com"))
-
-;;; Define how Gnus is to read your mail.  We read mail from
-;;; your ISP's POP server.
-(setq mail-sources '((pop :server "pop.your-isp.com")))
-
-;;; Say how Gnus is to store the mail.  We use nnml groups.
-(setq gnus-secondary-select-methods '((nnml "")))
-
-;;; Make Gnus into an offline newsreader.
-(gnus-agentize)
-@end lisp
-
-That should be it, basically.  Put that in your @file{~/.gnus.el} file,
-edit to suit your needs, start up PPP (or whatever), and type @kbd{M-x
-gnus}.
-
-If this is the first time you've run Gnus, you will be subscribed
-automatically to a few default newsgroups.  You'll probably want to
-subscribe to more groups, and to do that, you have to query the
-@sc{nntp} server for a complete list of groups with the @kbd{A A}
-command.  This usually takes quite a while, but you only have to do it
-once.
-
-After reading and parsing a while, you'll be presented with a list of
-groups.  Subscribe to the ones you want to read with the @kbd{u}
-command.  @kbd{l} to make all the killed groups disappear after you've
-subscribe to all the groups you want to read.  (@kbd{A k} will bring
-back all the killed groups.)
-
-You can now read the groups at once, or you can download the articles
-with the @kbd{J s} command.  And then read the rest of this manual to
-find out which of the other gazillion things you want to customize.
-
-
-@node Batching Agents
-@subsection Batching Agents
-
-Having the Gnus Agent fetch articles (and post whatever messages you've
-written) is quite easy once you've gotten things set up properly.  The
-following shell script will do everything that is necessary:
-
-@example
-#!/bin/sh
-emacs -batch -l ~/.emacs -f gnus-agent-batch >/dev/null
-@end example
-
-
-@node Agent Caveats
-@subsection Agent Caveats
-
-The Gnus Agent doesn't seem to work like most other offline
-newsreaders.  Here are some common questions that some imaginary people
-may ask:
-
-@table @dfn
-@item If I read an article while plugged, do they get entered into the
-Agent?
-
-@strong{No.}
-
-@item If I read an article while plugged, and the article already exists
-in the Agent, will it get downloaded once more?
-
-@strong{Yes.}
-
-@end table
-
-In short, when Gnus is unplugged, it only looks into the locally stored
-articles; when it's plugged, it only talks to your ISP.

-
-@node Scoring
-@chapter Scoring
-@cindex scoring
-
-Other people use @dfn{kill files}, but we here at Gnus Towers like
-scoring better than killing, so we'd rather switch than fight.  They do
-something completely different as well, so sit up straight and pay
-attention!
-
-@vindex gnus-summary-mark-below
-All articles have a default score (@code{gnus-summary-default-score}),
-which is 0 by default.  This score may be raised or lowered either
-interactively or by score files.  Articles that have a score lower than
-@code{gnus-summary-mark-below} are marked as read.
-
-Gnus will read any @dfn{score files} that apply to the current group
-before generating the summary buffer.
-
-There are several commands in the summary buffer that insert score
-entries based on the current article.  You can, for instance, ask Gnus to
-lower or increase the score of all articles with a certain subject.
-
-There are two sorts of scoring entries: Permanent and temporary.
-Temporary score entries are self-expiring entries.  Any entries that are
-temporary and have not been used for, say, a week, will be removed
-silently to help keep the sizes of the score files down.

-@node Summary Score Commands
-@section Summary Score Commands
-@cindex score commands
-
-The score commands that alter score entries do not actually modify real
-score files.  That would be too inefficient.  Gnus maintains a cache of
-previously loaded score files, one of which is considered the
-@dfn{current score file alist}.  The score commands simply insert
-entries into this list, and upon group exit, this list is saved.
-
-The current score file is by default the group's local score file, even
-if no such score file actually exists.  To insert score commands into
-some other score file (e.g. @file{all.SCORE}), you must first make this
-score file the current one.
-
-General score commands that don't actually change the score file:
-
-@table @kbd
-
-@item V s
-@kindex V s (Summary)
-@findex gnus-summary-set-score

-@end table
-
-The keystrokes for actually making score entries follow a very regular
-pattern, so there's no need to list all the commands.  (Hundreds of
-them.)
-
-@findex gnus-summary-increase-score
-@findex gnus-summary-lower-score
-
-@enumerate
-@item
-The first key is either @kbd{I} (upper case i) for increasing the score
-or @kbd{L} for lowering the score.
-@item
-The second key says what header you want to score on.  The following
-keys are available:
-@table @kbd
-
-@item a
-Score on the author name.
-
-@item s
-Score on the subject line.
-
-@item x
-Score on the @code{Xref} line---i.e., the cross-posting line.
-
-@item r
-Score on the @code{References} line.
-
-@item d
-Score on the date.
-
-@item l
-Score on the number of lines.
-
-@item i
-Score on the @code{Message-ID} header.
-
-@item f
-Score on followups---this matches the author name, and adds scores to
-the followups to this author.
-
-@item b
-Score on the body.
-
-@item h
-Score on the head.
-
-@item t
-Score on thread.
-
-@end table
-
-@item
-The third key is the match type.  Which match types are valid depends on
-what headers you are scoring on.
-
-@table @code
-
-@item strings
-
-@table @kbd
-
-@item e
-Exact matching.
-
-@item s
-Substring matching.
-
-@item f
-Fuzzy matching (@pxref{Fuzzy Matching}).
-
-@item r
-Regexp matching
-@end table
-
-@item date
-@table @kbd
-
-@item b
-Before date.
-
-@item a
-After date.
-
-@item n
-This date.
-@end table
-
-@item number
-@table @kbd
-
-@item <
-Less than number.
-
-@item =
-Equal to number.
-
-@item >
-Greater than number.
-@end table
-@end table
-
-@item
-The fourth and final key says whether this is a temporary (i.e., expiring)
-score entry, or a permanent (i.e., non-expiring) score entry, or whether
-it is to be done immediately, without adding to the score file.
-@table @kbd
-
-@item t
-Temporary score entry.
-
-@item p
-Permanent score entry.
-
-@item i
-Immediately scoring.
-@end table
-
-@end enumerate
-
-So, let's say you want to increase the score on the current author with
-exact matching permanently: @kbd{I a e p}.  If you want to lower the
-score based on the subject line, using substring matching, and make a
-temporary score entry: @kbd{L s s t}.  Pretty easy.
-
-To make things a bit more complicated, there are shortcuts.  If you use
-a capital letter on either the second or third keys, Gnus will use
-defaults for the remaining one or two keystrokes.  The defaults are
-``substring'' and ``temporary''.  So @kbd{I A} is the same as @kbd{I a s
-t}, and @kbd{I a R} is the same as @kbd{I a r t}.
-
-These functions take both the numerical prefix and the symbolic prefix
-(@pxref{Symbolic Prefixes}).  A numerical prefix says how much to lower
-(or increase) the score of the article.  A symbolic prefix of @code{a}
-says to use the @file{all.SCORE} file for the command instead of the
-current score file.
-
-@vindex gnus-score-mimic-keymap
-The @code{gnus-score-mimic-keymap} says whether these commands will
-pretend they are keymaps or not.

-
-@item gnus-use-scoring
-@vindex gnus-use-scoring
-If @code{nil}, Gnus will not check for score files, and will not, in
-general, do any score-related work.  This is @code{t} by default.
-
-@item gnus-kill-killed
-@vindex gnus-kill-killed
-If this variable is @code{nil}, Gnus will never apply score files to
-articles that have already been through the kill process.  While this
-may save you lots of time, it also means that if you apply a kill file
-to a group, and then change the kill file and want to run it over you
-group again to kill more articles, it won't work.  You have to set this
-variable to @code{t} to do that.  (It is @code{t} by default.)
-
-@item gnus-kill-files-directory
-@vindex gnus-kill-files-directory
-All kill and score files will be stored in this directory, which is
-initialized from the @code{SAVEDIR} environment variable by default.
-This is @file{~/News/} by default.
-
-@item gnus-score-file-suffix
-@vindex gnus-score-file-suffix
-Suffix to add to the group name to arrive at the score file name
-(@samp{SCORE} by default.)
-
-@item gnus-score-uncacheable-files
-@vindex gnus-score-uncacheable-files
-@cindex score cache
-All score files are normally cached to avoid excessive re-loading of
-score files.  However, if this might make your Emacs grow big and
-bloated, so this regexp can be used to weed out score files unlikely to be needed again.  It would be a bad idea to deny caching of
-@file{all.SCORE}, while it might be a good idea to not cache
-@file{comp.infosystems.www.authoring.misc.ADAPT}.  In fact, this
-variable is @samp{ADAPT$} by default, so no adaptive score files will
-be cached.
-
-@item gnus-save-score
-@vindex gnus-save-score
-If you have really complicated score files, and do lots of batch
-scoring, then you might set this variable to @code{t}.  This will make
-Gnus save the scores into the @file{.newsrc.eld} file.
-
-If you do not set this to @code{t}, then manual scores (like those set
-with @kbd{V s} (@code{gnus-summary-set-score})) will not be preserved
-across group visits.
-
-@item gnus-score-interactive-default-score
-@vindex gnus-score-interactive-default-score
-Score used by all the interactive raise/lower commands to raise/lower
-score with.  Default is 1000, which may seem excessive, but this is to
-ensure that the adaptive scoring scheme gets enough room to play with.
-We don't want the small changes from the adaptive scoring to overwrite
-manually entered data.
-
-@item gnus-summary-default-score
-@vindex gnus-summary-default-score
-Default score of an article, which is 0 by default.
-
-@item gnus-summary-expunge-below
-@vindex gnus-summary-expunge-below
-Don't display the summary lines of articles that have scores lower than
-this variable.  This is @code{nil} by default, which means that no
-articles will be hidden.  This variable is local to the summary buffers,
-and has to be set from @code{gnus-summary-mode-hook}.
-
-@item gnus-score-over-mark
-@vindex gnus-score-over-mark
-Mark (in the third column) used for articles with a score over the
-default.  Default is @samp{+}.
-
-@item gnus-score-below-mark
-@vindex gnus-score-below-mark
-Mark (in the third column) used for articles with a score below the
-default.  Default is @samp{-}.
-
-@item gnus-score-find-score-files-function
-@vindex gnus-score-find-score-files-function
-Function used to find score files for the current group.  This function
-is called with the name of the group as the argument.
-
-Predefined functions available are:
-@table @code
-
-@item gnus-score-find-single
-@findex gnus-score-find-single
-Only apply the group's own score file.
-
-@item gnus-score-find-bnews
-@findex gnus-score-find-bnews
-Apply all score files that match, using bnews syntax.  This is the
-default.  If the current group is @samp{gnu.emacs.gnus}, for instance,
-@file{all.emacs.all.SCORE}, @file{not.alt.all.SCORE} and
-@file{gnu.all.SCORE} would all apply.  In short, the instances of
-@samp{all} in the score file names are translated into @samp{.*}, and
-then a regexp match is done.
-
-This means that if you have some score entries that you want to apply to
-all groups, then you put those entries in the @file{all.SCORE} file.
-
-The score files are applied in a semi-random order, although Gnus will
-try to apply the more general score files before the more specific score
-files.  It does this by looking at the number of elements in the score
-file names---discarding the @samp{all} elements.
-
-@item gnus-score-find-hierarchical
-@findex gnus-score-find-hierarchical
-Apply all score files from all the parent groups.  This means that you
-can't have score files like @file{all.SCORE}, but you can have
-@file{SCORE}, @file{comp.SCORE} and @file{comp.emacs.SCORE}.
-
-@end table
-This variable can also be a list of functions.  In that case, all these
-functions will be called, and all the returned lists of score files will
-be applied.  These functions can also return lists of score alists
-directly.  In that case, the functions that return these non-file score
-alists should probably be placed before the ``real'' score file
-functions, to ensure that the last score file returned is the local
-score file.  Phu.
-
-@item gnus-score-expiry-days
-@vindex gnus-score-expiry-days
-This variable says how many days should pass before an unused score file
-entry is expired.  If this variable is @code{nil}, no score file entries
-are expired.  It's 7 by default.
-
-@item gnus-update-score-entry-dates
-@vindex gnus-update-score-entry-dates
-If this variable is non-@code{nil}, matching score entries will have
-their dates updated.  (This is how Gnus controls expiry---all
-non-matching entries will become too old while matching entries will
-stay fresh and young.)  However, if you set this variable to @code{nil},
-even matching entries will grow old and will have to face that oh-so
-grim reaper.
-
-@item gnus-score-after-write-file-function
-@vindex gnus-score-after-write-file-function
-Function called with the name of the score file just written.
-
-@item gnus-score-thread-simplify
-@vindex gnus-score-thread-simplify
-If this variable is non-@code{nil}, article subjects will be simplified
-for subject scoring purposes in the same manner as with
-threading---according to the current value of
-gnus-simplify-subject-functions.  If the scoring entry uses
-@code{substring} or @code{exact} matching, the match will also be
-simplified in this manner.

-
-@node Score File Format
-@section Score File Format
-@cindex score file format
-
-A score file is an @code{emacs-lisp} file that normally contains just a
-single form.  Casual users are not expected to edit these files;
-everything can be changed from the summary buffer.
-
-Anyway, if you'd like to dig into it yourself, here's an example:
-
-@lisp
-(("from"
-  ("Lars Ingebrigtsen" -10000)
-  ("Per Abrahamsen")
-  ("larsi\\|lmi" -50000 nil R))

- (orphan -10)
- (adapt t)
- (files "/hom/larsi/News/gnu.SCORE")
- (exclude-files "all.SCORE")
- (local (gnus-newsgroup-auto-expire t)
-        (gnus-summary-make-false-root empty))
- (eval (ding)))
-@end lisp
-
-This example demonstrates most score file elements.  For a different
-approach, see @pxref{Advanced Scoring}.
-
-Even though this looks much like lisp code, nothing here is actually
-@code{eval}ed.  The lisp reader is used to read this form, though, so it
-has to be valid syntactically, if not semantically.
-
-Six keys are supported by this alist:
-
-@table @code
-
-@item STRING
-If the key is a string, it is the name of the header to perform the
-match on.  Scoring can only be performed on these eight headers:
-@code{From}, @code{Subject}, @code{References}, @code{Message-ID},
-@code{Xref}, @code{Lines}, @code{Chars} and @code{Date}.  In addition to
-these headers, there are three strings to tell Gnus to fetch the entire
-article and do the match on larger parts of the article: @code{Body}
-will perform the match on the body of the article, @code{Head} will
-perform the match on the head of the article, and @code{All} will
-perform the match on the entire article.  Note that using any of these
-last three keys will slow down group entry @emph{considerably}.  The
-final ``header'' you can score on is @code{Followup}.  These score
-entries will result in new score entries being added for all follow-ups
-to articles that matches these score entries.
-
-Following this key is a arbitrary number of score entries, where each
-score entry has one to four elements.
-@enumerate
-
-@item
-The first element is the @dfn{match element}.  On most headers this will
-be a string, but on the Lines and Chars headers, this must be an
-integer.
-
-@item
-If the second element is present, it should be a number---the @dfn{score
-element}.  This number should be an integer in the neginf to posinf
-interval.  This number is added to the score of the article if the match
-is successful.  If this element is not present, the
-@code{gnus-score-interactive-default-score} number will be used
-instead.  This is 1000 by default.
-
-@item
-If the third element is present, it should be a number---the @dfn{date
-element}.  This date says when the last time this score entry matched,
-which provides a mechanism for expiring the score entries.  It this
-element is not present, the score entry is permanent.  The date is
-represented by the number of days since December 31, 1 BCE.
-
-@item
-If the fourth element is present, it should be a symbol---the @dfn{type
-element}.  This element specifies what function should be used to see
-whether this score entry matches the article.  What match types that can
-be used depends on what header you wish to perform the match on.
-@table @dfn
-
-@item From, Subject, References, Xref, Message-ID
-For most header types, there are the @code{r} and @code{R} (regexp), as
-well as @code{s} and @code{S} (substring) types, and @code{e} and
-@code{E} (exact match), and @code{w} (word match) types.  If this
-element is not present, Gnus will assume that substring matching should
-be used.  @code{R}, @code{S}, and @code{E} differ from the others in
-that the matches will be done in a case-sensitive manner.  All these
-one-letter types are really just abbreviations for the @code{regexp},
-@code{string}, @code{exact}, and @code{word} types, which you can use
-instead, if you feel like.
-
-@item Lines, Chars
-These two headers use different match types: @code{<}, @code{>},
-@code{=}, @code{>=} and @code{<=}.
-
-These predicates are true if
-
-@example
-(PREDICATE HEADER MATCH)
-@end example
-
-evaluates to non-@code{nil}.  For instance, the advanced match
-@code{("lines" 4 <)} (@pxref{Advanced Scoring}) will result in the
-following form:
-
-@lisp
-(< header-value 4)
-@end lisp
-
-Or to put it another way: When using @code{<} on @code{Lines} with 4 as
-the match, we get the score added if the article has less than 4 lines.
-(It's easy to get confused and think it's the other way around.  But
-it's not.  I think.)
-
-When matching on @code{Lines}, be careful because some backends (like
-@code{nndir}) do not generate @code{Lines} header, so every article ends
-up being marked as having 0 lines.  This can lead to strange results if
-you happen to lower score of the articles with few lines.
-
-@item Date
-For the Date header we have three kinda silly match types:
-@code{before}, @code{at} and @code{after}.  I can't really imagine this
-ever being useful, but, like, it would feel kinda silly not to provide
-this function.  Just in case.  You never know.  Better safe than sorry.
-Once burnt, twice shy.  Don't judge a book by its cover.  Never not have
-sex on a first date.  (I have been told that at least one person, and I
-quote, ``found this function indispensable'', however.)
-
-@cindex ISO8601
-@cindex date
-A more useful match type is @code{regexp}.  With it, you can match the
-date string using a regular expression.  The date is normalized to
-ISO8601 compact format first---@var{YYYYMMDD}@code{T}@var{HHMMSS}.  If
-you want to match all articles that have been posted on April 1st in
-every year, you could use @samp{....0401.........} as a match string,
-for instance.  (Note that the date is kept in its original time zone, so
-this will match articles that were posted when it was April 1st where
-the article was posted from.  Time zones are such wholesome fun for the
-whole family, eh?)
-
-@item Head, Body, All
-These three match keys use the same match types as the @code{From} (etc)
-header uses.
-
-@item Followup
-This match key is somewhat special, in that it will match the
-@code{From} header, and affect the score of not only the matching
-articles, but also all followups to the matching articles.  This allows
-you e.g. increase the score of followups to your own articles, or
-decrease the score of followups to the articles of some known
-trouble-maker.  Uses the same match types as the @code{From} header
-uses.  (Using this match key will lead to creation of @file{ADAPT}
-files.)
-
-@item Thread
-This match key works along the same lines as the @code{Followup} match
-key.  If you say that you want to score on a (sub-)thread started by an
-article with a @code{Message-ID} @var{x}, then you add a @samp{thread}
-match.  This will add a new @samp{thread} match for each article that
-has @var{x} in its @code{References} header.  (These new @samp{thread}
-matches will use the @code{Message-ID}s of these matching articles.)
-This will ensure that you can raise/lower the score of an entire thread,
-even though some articles in the thread may not have complete
-@code{References} headers.  Note that using this may lead to
-undeterministic scores of the articles in the thread.  (Using this match
-key will lead to creation of @file{ADAPT} files.)

-@item eval
-The value of this entry will be @code{eval}el.  This element will be
-ignored when handling global score files.
-
-@item read-only
-Read-only score files will not be updated or saved.  Global score files
-should feature this atom (@pxref{Global Score Files}).  (Note:
-@dfn{Global} here really means @dfn{global}; not your personal
-apply-to-all-groups score files.)
-
-@item orphan
-The value of this entry should be a number.  Articles that do not have
-parents will get this number added to their scores.  Imagine you follow
-some high-volume newsgroup, like @samp{comp.lang.c}.  Most likely you
-will only follow a few of the threads, also want to see any new threads.
-
-You can do this with the following two score file entries:
-
-@example
-        (orphan -500)
-        (mark-and-expunge -100)
-@end example
-
-When you enter the group the first time, you will only see the new
-threads.  You then raise the score of the threads that you find
-interesting (with @kbd{I T} or @kbd{I S}), and ignore (@kbd{C y}) the
-rest.  Next time you enter the group, you will see new articles in the
-interesting threads, plus any new threads.
-
-I.e.---the orphan score atom is for high-volume groups where there
-exist a few interesting threads which can't be found automatically by
-ordinary scoring rules.
-
-@item adapt
-This entry controls the adaptive scoring.  If it is @code{t}, the
-default adaptive scoring rules will be used.  If it is @code{ignore}, no
-adaptive scoring will be performed on this group.  If it is a list, this
-list will be used as the adaptive scoring rules.  If it isn't present,
-or is something other than @code{t} or @code{ignore}, the default
-adaptive scoring rules will be used.  If you want to use adaptive
-scoring on most groups, you'd set @code{gnus-use-adaptive-scoring} to
-@code{t}, and insert an @code{(adapt ignore)} in the groups where you do
-not want adaptive scoring.  If you only want adaptive scoring in a few
-groups, you'd set @code{gnus-use-adaptive-scoring} to @code{nil}, and
-insert @code{(adapt t)} in the score files of the groups where you want
-it.
-
-@item adapt-file
-All adaptive score entries will go to the file named by this entry.  It
-will also be applied when entering the group.  This atom might be handy
-if you want to adapt on several groups at once, using the same adaptive
-file for a number of groups.
-
-@item local
-@cindex local variables
-The value of this entry should be a list of @code{(VAR VALUE)} pairs.
-Each @var{var} will be made buffer-local to the current summary buffer,
-and set to the value specified.  This is a convenient, if somewhat
-strange, way of setting variables in some groups if you don't like hooks
-much.  Note that the @var{value} won't be evaluated.

-@node Score File Editing
-@section Score File Editing
-
-You normally enter all scoring commands from the summary buffer, but you
-might feel the urge to edit them by hand as well, so we've supplied you
-with a mode for that.
-
-It's simply a slightly customized @code{emacs-lisp} mode, with these
-additional commands:
-
-@table @kbd
-
-@item C-c C-c
-@kindex C-c C-c (Score)
-@findex gnus-score-edit-done
-Save the changes you have made and return to the summary buffer

-@kindex C-c C-d (Score)
-@findex gnus-score-edit-insert-date
-Insert the current date in numerical format
-(@code{gnus-score-edit-insert-date}).  This is really the day number, if
-you were wondering.
-
-@item C-c C-p
-@kindex C-c C-p (Score)
-@findex gnus-score-pretty-print
-The adaptive score files are saved in an unformatted fashion.  If you
-intend to read one of these files, you want to @dfn{pretty print} it
-first.  This command (@code{gnus-score-pretty-print}) does that for
-you.
-
-@end table
-
-Type @kbd{M-x gnus-score-mode} to use this mode.
-
-@vindex gnus-score-mode-hook
-@code{gnus-score-menu-hook} is run in score mode buffers.
-
-In the summary buffer you can use commands like @kbd{V f} and @kbd{V
-e} to begin editing score files.
-
-
-@node Adaptive Scoring
-@section Adaptive Scoring
-@cindex adaptive scoring
-
-If all this scoring is getting you down, Gnus has a way of making it all
-happen automatically---as if by magic.  Or rather, as if by artificial
-stupidity, to be precise.
-
-@vindex gnus-use-adaptive-scoring
-When you read an article, or mark an article as read, or kill an
-article, you leave marks behind.  On exit from the group, Gnus can sniff
-these marks and add score elements depending on what marks it finds.
-You turn on this ability by setting @code{gnus-use-adaptive-scoring} to
-@code{t} or @code{(line)}.  If you want score adaptively on separate
-words appearing in the subjects, you should set this variable to
-@code{(word)}.  If you want to use both adaptive methods, set this
-variable to @code{(word line)}.
-
-@vindex gnus-default-adaptive-score-alist
-To give you complete control over the scoring process, you can customize
-the @code{gnus-default-adaptive-score-alist} variable.  For instance, it
-might look something like this:
-
-@lisp
-(defvar gnus-default-adaptive-score-alist
-  '((gnus-unread-mark)
-    (gnus-ticked-mark (from 4))
-    (gnus-dormant-mark (from 5))
-    (gnus-del-mark (from -4) (subject -1))
-    (gnus-read-mark (from 4) (subject 2))
-    (gnus-expirable-mark (from -1) (subject -1))
-    (gnus-killed-mark (from -1) (subject -3))
-    (gnus-kill-file-mark)
-    (gnus-ancient-mark)
-    (gnus-low-score-mark)
-    (gnus-catchup-mark (from -1) (subject -1))))
-@end lisp
-
-As you see, each element in this alist has a mark as a key (either a
-variable name or a ``real'' mark---a character).  Following this key is
-a arbitrary number of header/score pairs.  If there are no header/score
-pairs following the key, no adaptive scoring will be done on articles
-that have that key as the article mark.  For instance, articles with
-@code{gnus-unread-mark} in the example above will not get adaptive score
-entries.
-
-Each article can have only one mark, so just a single of these rules
-will be applied to each article.
-
-To take @code{gnus-del-mark} as an example---this alist says that all
-articles that have that mark (i.e., are marked with @samp{D}) will have a
-score entry added to lower based on the @code{From} header by -4, and
-lowered by @code{Subject} by -1.  Change this to fit your prejudices.
-
-If you have marked 10 articles with the same subject with
-@code{gnus-del-mark}, the rule for that mark will be applied ten times.
-That means that that subject will get a score of ten times -1, which
-should be, unless I'm much mistaken, -10.
-
-If you have auto-expirable (mail) groups (@pxref{Expiring Mail}), all
-the read articles will be marked with the @samp{E} mark.  This'll
-probably make adaptive scoring slightly impossible, so auto-expiring and
-adaptive scoring doesn't really mix very well.
-
-The headers you can score on are @code{from}, @code{subject},
-@code{message-id}, @code{references}, @code{xref}, @code{lines},
-@code{chars} and @code{date}.  In addition, you can score on
-@code{followup}, which will create an adaptive score entry that matches
-on the @code{References} header using the @code{Message-ID} of the
-current article, thereby matching the following thread.
-
-You can also score on @code{thread}, which will try to score all
-articles that appear in a thread.  @code{thread} matches uses a
-@code{Message-ID} to match on the @code{References} header of the
-article.  If the match is made, the @code{Message-ID} of the article is
-added to the @code{thread} rule.  (Think about it.  I'd recommend two
-aspirins afterwards.)
-
-If you use this scheme, you should set the score file atom @code{mark}
-to something small---like -300, perhaps, to avoid having small random
-changes result in articles getting marked as read.
-
-After using adaptive scoring for a week or so, Gnus should start to
-become properly trained and enhance the authors you like best, and kill
-the authors you like least, without you having to say so explicitly.
-
-You can control what groups the adaptive scoring is to be performed on
-by using the score files (@pxref{Score File Format}).  This will also
-let you use different rules in different groups.
-
-@vindex gnus-adaptive-file-suffix
-The adaptive score entries will be put into a file where the name is the
-group name with @code{gnus-adaptive-file-suffix} appended.  The default
-is @samp{ADAPT}.
-
-@vindex gnus-score-exact-adapt-limit
-When doing adaptive scoring, substring or fuzzy matching would probably
-give you the best results in most cases.  However, if the header one
-matches is short, the possibility for false positives is great, so if
-the length of the match is less than
-@code{gnus-score-exact-adapt-limit}, exact matching will be used.  If
-this variable is @code{nil}, exact matching will always be used to avoid
-this problem.
-
-@vindex gnus-default-adaptive-word-score-alist
-As mentioned above, you can adapt either on individual words or entire
-headers.  If you adapt on words, the
-@code{gnus-default-adaptive-word-score-alist} variable says what score
-each instance of a word should add given a mark.
-
-@lisp
-(setq gnus-default-adaptive-word-score-alist
-      `((,gnus-read-mark . 30)
-        (,gnus-catchup-mark . -10)
-        (,gnus-killed-mark . -20)
-        (,gnus-del-mark . -15)))
-@end lisp
-
-This is the default value.  If you have adaption on words enabled, every
-word that appears in subjects of articles marked with
-@code{gnus-read-mark} will result in a score rule that increase the
-score with 30 points.
-
-@vindex gnus-default-ignored-adaptive-words
-@vindex gnus-ignored-adaptive-words
-Words that appear in the @code{gnus-default-ignored-adaptive-words} list
-will be ignored.  If you wish to add more words to be ignored, use the
-@code{gnus-ignored-adaptive-words} list instead.
-
-@vindex gnus-adaptive-word-syntax-table
-When the scoring is done, @code{gnus-adaptive-word-syntax-table} is the
-syntax table in effect.  It is similar to the standard syntax table, but
-it considers numbers to be non-word-constituent characters.
-
-@vindex gnus-adaptive-word-minimum
-If @code{gnus-adaptive-word-minimum} is set to a number, the adaptive
-word scoring process will never bring down the score of an article to
-below this number.  The default is @code{nil}.
-
-@vindex gnus-adaptive-word-no-group-words
-If @code{gnus-adaptive-word-no-group-words} is set to @code{t}, gnus
-won't adaptively word score any of the words in the group name.  Useful
-for groups like @samp{comp.editors.emacs}, where most of the subject
-lines contain the word @samp{emacs}.
-
-After using this scheme for a while, it might be nice to write a
-@code{gnus-psychoanalyze-user} command to go through the rules and see
-what words you like and what words you don't like.  Or perhaps not.
-
-Note that the adaptive word scoring thing is highly experimental and is
-likely to change in the future.  Initial impressions seem to indicate
-that it's totally useless as it stands.  Some more work (involving more
-rigorous statistical methods) will have to be done to make this useful.
-
-
-@node Home Score File
-@section Home Score File
-
-The score file where new score file entries will go is called the
-@dfn{home score file}.  This is normally (and by default) the score file
-for the group itself.  For instance, the home score file for
-@samp{gnu.emacs.gnus} is @file{gnu.emacs.gnus.SCORE}.
-
-However, this may not be what you want.  It is often convenient to share
-a common home score file among many groups---all @samp{emacs} groups
-could perhaps use the same home score file.
-
-@vindex gnus-home-score-file
-The variable that controls this is @code{gnus-home-score-file}.  It can
-be:
-
-@enumerate
-@item
-A string.  Then this file will be used as the home score file for all
-groups.
-
-@item
-A function. The result of this function will be used as the home score
-file.  The function will be called with the name of the group as the
-parameter.
-
-@item
-A list.  The elements in this list can be:
-
-@enumerate
-@item
-@code{(@var{regexp} @var{file-name})}.  If the @var{regexp} matches the
-group name, the @var{file-name} will will be used as the home score file.
-
-@item
-A function. If the function returns non-nil, the result will be used as
-the home score file.
-
-@item
-A string.  Use the string as the home score file.
-@end enumerate
-
-The list will be traversed from the beginning towards the end looking
-for matches.
-
-@end enumerate
-
-So, if you want to use just a single score file, you could say:
-
-@lisp
-(setq gnus-home-score-file
-      "my-total-score-file.SCORE")
-@end lisp
-
-If you want to use @file{gnu.SCORE} for all @samp{gnu} groups and
-@file{rec.SCORE} for all @samp{rec} groups (and so on), you can say:
-
-@findex gnus-hierarchial-home-score-file
-@lisp
-(setq gnus-home-score-file
-      'gnus-hierarchial-home-score-file)
-@end lisp
-
-This is a ready-made function provided for your convenience.
-Other functions include
-
-@table @code
-@item gnus-current-home-score-file
-@findex gnus-current-home-score-file
-Return the ``current'' regular score file.  This will make scoring
-commands add entry to the ``innermost'' matching score file.
-
-@end table
-
-If you want to have one score file for the @samp{emacs} groups and
-another for the @samp{comp} groups, while letting all other groups use
-their own home score files:
-
-@lisp
-(setq gnus-home-score-file
-      ;; All groups that match the regexp "\\.emacs"
-      '(("\\.emacs" "emacs.SCORE")
-        ;; All the comp groups in one score file
-        ("^comp" "comp.SCORE")))
-@end lisp
-
-@vindex gnus-home-adapt-file
-@code{gnus-home-adapt-file} works exactly the same way as
-@code{gnus-home-score-file}, but says what the home adaptive score file
-is instead.  All new adaptive file entries will go into the file
-specified by this variable, and the same syntax is allowed.
-
-In addition to using @code{gnus-home-score-file} and
-@code{gnus-home-adapt-file}, you can also use group parameters
-(@pxref{Group Parameters}) and topic parameters (@pxref{Topic
-Parameters}) to achieve much the same.  Group and topic parameters take
-precedence over this variable.
-
-
-@node Followups To Yourself
-@section Followups To Yourself
-
-Gnus offers two commands for picking out the @code{Message-ID} header in
-the current buffer.  Gnus will then add a score rule that scores using
-this @code{Message-ID} on the @code{References} header of other
-articles.  This will, in effect, increase the score of all articles that
-respond to the article in the current buffer.  Quite useful if you want
-to easily note when people answer what you've said.
-
-@table @code
-
-@item gnus-score-followup-article
-@findex gnus-score-followup-article
-This will add a score to articles that directly follow up your own
-article.
-
-@item gnus-score-followup-thread
-@findex gnus-score-followup-thread
-This will add a score to all articles that appear in a thread ``below''
-your own article.
-@end table
-
-@vindex message-sent-hook
-These two functions are both primarily meant to be used in hooks like
-@code{message-sent-hook}.
-
-If you look closely at your own @code{Message-ID}, you'll notice that
-the first two or three characters are always the same.  Here's two of
-mine:
-
-@example
-<x6u3u47icf.fsf@@eyesore.no>
-<x6sp9o7ibw.fsf@@eyesore.no>
-@end example
-
-So ``my'' ident on this machine is @samp{x6}.  This can be
-exploited---the following rule will raise the score on all followups to
-myself:
-
-@lisp
-("references"
- ("<x6[0-9a-z]+\\.fsf\\(_-_\\)?@@.*eyesore.no>"
-  1000 nil r))
-@end lisp
-
-Whether it's the first two or first three characters that are ``yours''
-is system-dependent.

-@end lisp
-
-@item Matching on the body
-This is generally not a very good idea---it takes a very long time.
-Gnus actually has to fetch each individual article from the server.  But
-you might want to anyway, I guess.  Even though there are three match
-keys (@code{Head}, @code{Body} and @code{All}), you should choose one
-and stick with it in each score file.  If you use any two, each article
-will be fetched @emph{twice}.  If you want to match a bit on the
-@code{Head} and a bit on the @code{Body}, just use @code{All} for all
-the matches.
-
-@item Marking as read
-You will probably want to mark articles that have scores below a certain
-number as read.  This is most easily achieved by putting the following
-in your @file{all.SCORE} file:
-@lisp
-((mark -100))
-@end lisp
-You may also consider doing something similar with @code{expunge}.
-
-@item Negated character classes
-If you say stuff like @code{[^abcd]*}, you may get unexpected results.
-That will match newlines, which might lead to, well, The Unknown.  Say
-@code{[^abcd\n]*} instead.

-(("subject"
-  ("Sex with Emacs" 2))
- (mark 1)

-
-Note that, at present, using this option will slow down group entry
-somewhat.  (That is---a lot.)
-
-If you want to start maintaining score files for other people to use,
-just put your score file up for anonymous ftp and announce it to the

-
-Here are some tips for the would-be retro-moderator, off the top of my
-head:
-
-@itemize @bullet
-
-@item
-Articles heavily crossposted are probably junk.
-@item
-To lower a single inappropriate article, lower by @code{Message-ID}.
-@item
-Particularly brilliant authors can be raised on a permanent basis.
-@item
-Authors that repeatedly post off-charter for the group can safely be
-lowered out of existence.
-@item
-Set the @code{mark} and @code{expunge} atoms to obliterate the nastiest
-articles completely.
-
-@item
-Use expiring score entries to keep the size of the file down.  You
-should probably have a long expiry period, though, as some sites keep
-old articles for a long time.
-@end itemize
-
-... I wonder whether other newsreaders will support global score files
-in the future.  @emph{Snicker}.  Yup, any day now, newsreaders like Blue
-Wave, xrn and 1stReader are bound to implement scoring.  Should we start
-holding our breath yet?
-
-
-@node Kill Files
-@section Kill Files
-@cindex kill files
-
-Gnus still supports those pesky old kill files.  In fact, the kill file
-entries can now be expiring, which is something I wrote before Daniel
-Quinlan thought of doing score files, so I've left the code in there.
-
-In short, kill processing is a lot slower (and I do mean @emph{a lot})
-than score processing, so it might be a good idea to rewrite your kill
-files into score files.
-
-Anyway, a kill file is a normal @code{emacs-lisp} file.  You can put any
-forms into this file, which means that you can use kill files as some
-sort of primitive hook function to be run on group entry, even though

-from GroupLens in one of three ways controlled by the variable
-@code{gnus-grouplens-override-scoring}.
-
-@vindex gnus-grouplens-override-scoring
-There are three ways to display predictions in grouplens.  You may
-choose to have the GroupLens scores contribute to, or override the
-regular gnus scoring mechanism. override is the default; however, some
-people prefer to see the Gnus scores plus the grouplens scores.  To get
-the separate scoring behavior you need to set
-@code{gnus-grouplens-override-scoring} to @code{'separate}.  To have the
-GroupLens predictions combined with the grouplens scores set it to
-@code{'override} and to combine the scores set
-@code{gnus-grouplens-override-scoring} to @code{'combine}.  When you use
-the combine option you will also want to set the values for
-@code{grouplens-prediction-offset} and
-@code{grouplens-score-scale-factor}.
-
-@vindex grouplens-prediction-display
-In either case, GroupLens gives you a few choices for how you would like

-@node Advanced Scoring Syntax
-@subsection Advanced Scoring Syntax
-
-Ordinary scoring rules have a string as the first element in the rule.
-Advanced scoring rules have a list as the first element.  The second
-element is the score to be applied if the first element evaluated to a
-non-@code{nil} value.
-
-These lists may consist of three logical operators, one redirection
-operator, and various match operators.
-
-Logical operators:
-
-@table @code
-@item &
-@itemx and
-This logical operator will evaluate each of its arguments until it finds
-one that evaluates to @code{false}, and then it'll stop.  If all arguments
-evaluate to @code{true} values, then this operator will return
-@code{true}.
-
-@item |
-@itemx or
-This logical operator will evaluate each of its arguments until it finds
-one that evaluates to @code{true}.  If no arguments are @code{true},
-then this operator will return @code{false}.
-
-@item !
-@itemx not
-@itemx ¬
-This logical operator only takes a single argument.  It returns the
-logical negation of the value of its argument.
-
-@end table
-
-There is an @dfn{indirection operator} that will make its arguments
-apply to the ancestors of the current article being scored.  For
-instance, @code{1-} will make score rules apply to the parent of the
-current article.  @code{2-} will make score rules apply to the
-grandparent of the current article.  Alternatively, you can write
-@code{^^}, where the number of @code{^}s (carets) says how far back into
-the ancestry you want to go.
-
-Finally, we have the match operators.  These are the ones that do the
-real work.  Match operators are header name strings followed by a match
-and a match type.  A typical match operator looks like @samp{("from"
-"Lars Ingebrigtsen" s)}.  The header names are the same as when using
-simple scoring, and the match types are also the same.

-@node Advanced Scoring Examples
-@subsection Advanced Scoring Examples

-Let's say you want to increase the score of articles written by Lars
-when he's talking about Gnus:
-
-@example
-((&
-  ("from" "Lars Ingebrigtsen")
-  ("subject" "Gnus"))
- 1000)
-@end example
-
-Quite simple, huh?
-
-When he writes long articles, he sometimes has something nice to say:
-
-@example
-((&
-  ("from" "Lars Ingebrigtsen")
-  (|
-   ("subject" "Gnus")
-   ("lines" 100 >)))
- 1000)
-@end example

-  (1- ("from" "Reig Eigir Logge")))
- -100000)
-@end example
-
-Everybody that follows up Redmondo when he writes about disappearing
-socks should have their scores raised, but only when they talk about
-white socks.  However, when Lars talks about socks, it's usually not
-very interesting:
-
-@example
-((&
-  (1-
-   (&
-    ("from" "redmondo@@.*no" r)
-    ("body" "disappearing.*socks" t)))
-  (! ("from" "Lars Ingebrigtsen"))

-
-The possibilities are endless.

-
-@node Advanced Scoring Tips
-@subsection Advanced Scoring Tips
-
-The @code{&} and @code{|} logical operators do short-circuit logic.
-That is, they stop processing their arguments when it's clear what the
-result of the operation will be.  For instance, if one of the arguments
-of an @code{&} evaluates to @code{false}, there's no point in evaluating
-the rest of the arguments.  This means that you should put slow matches
-(@samp{body}, @samp{header}) last and quick matches (@samp{from},
-@samp{subject}) first.
-
-The indirection arguments (@code{1-} and so on) will make their
-arguments work on previous generations of the thread.  If you say
-something like:
-
-@example
-...
-(1-
- (1-
-  ("from" "lars")))
-...
-@end example
-
-Then that means "score on the from header of the grandparent of the
-current article".  An indirection is quite fast, but it's better to say:
-
-@example
-(1-
- (&
-  ("from" "Lars")
-  ("subject" "Gnus")))
-@end example
-
-than it is to say:
-
-@example
-(&
- (1- ("from" "Lars"))
- (1- ("subject" "Gnus")))

-Gnus provides a mechanism for decaying scores to help with this problem.

-@end lisp
-
-@vindex gnus-score-decay-scale
-@vindex gnus-score-decay-constant
-@code{gnus-score-decay-constant} is 3 by default and
-@code{gnus-score-decay-scale} is 0.05.  This should cause the following:
-
-@enumerate
-@item
-Scores between -3 and 3 will be set to 0 when this function is called.
-
-@item
-Scores with magnitudes between 3 and 60 will be shrunk by 3.
-
-@item
-Scores with magnitudes greater than 60 will be shrunk by 5% of the
-score.
-@end enumerate
-
-If you don't like this decay function, write your own.  It is called
-with the score to be decayed as its only parameter, and it should return
-the new score, which should be an integer.
-
-Gnus will try to decay scores once a day.  If you haven't run Gnus for
-four days, Gnus will decay the scores four times, for instance.

-
-This is a method for figuring out what articles the user wants the
-command to be performed on.
-
-It goes like this:
-
-If the numeric prefix is N, perform the operation on the next N

-
-If there is neither a numeric prefix nor any articles marked with the
-process mark, just perform the operation on the current article.
-
-Quite simple, really, but it needs to be made clear so that surprises
-are avoided.
-
-Commands that react to the process mark will push the current list of

-This is all nice and well, but what if you want to give a command some
-additional information?  Well, what most commands do is interpret the

-@kindex M-x gnus-update-format
-@findex gnus-update-format
-Gnus includes a command to help you while creating your own format
-specs.  @kbd{M-x gnus-update-format} will @code{eval} the current form,
-update the spec in question and pop you to a buffer where you can
-examine the resulting lisp code to be run to generate the line.

-@node Formatting Basics
-@subsection Formatting Basics
-
-Each @samp{%} element will be replaced by some string or other when the
-buffer in question is generated.  @samp{%5y} means ``insert the @samp{y}
-spec, and pad with spaces to get a 5-character field''.
-
-As with normal C and Emacs Lisp formatting strings, the numerical
-modifier between the @samp{%} and the formatting type character will
-@dfn{pad} the output so that it is always at least that long.
-@samp{%5y} will make the field always (at least) five characters wide by
-padding with spaces to the left.  If you say @samp{%-5y}, it will pad to
-the right instead.
-
-You may also wish to limit the length of the field to protect against
-particularly wide values.  For that you can say @samp{%4,6y}, which
-means that the field will never be more than 6 characters wide and never
-less than 4 characters wide.

-@node Mode Line Formatting
-@subsection Mode Line Formatting
-
-Mode line formatting variables (e.g.,
-@code{gnus-summary-mode-line-format}) follow the same rules as other,
-buffer line oriented formatting variables (@pxref{Formatting Basics})
-with the following two differences:
-
-@enumerate
-
-@item
-There must be no newline (@samp{\n}) at the end.
-
-@item
-The special @samp{%%b} spec can be used to display the buffer name.
-Well, it's no spec at all, really---@samp{%%} is just a way to quote
-@samp{%} to allow it to pass through the formatting machinery unmangled,
-so that Emacs receives @samp{%b}, which is something the Emacs mode line
-display interprets to mean ``show the buffer name''.  For a full list of
-mode line specs Emacs understands, see the documentation of the
-@code{mode-line-format} variable.
-
-@end enumerate
-
-
-@node Advanced Formatting
-@subsection Advanced Formatting
-
-It is frequently useful to post-process the fields in some way.
-Padding, limiting, cutting off parts and suppressing certain values can
-be achieved by using @dfn{tilde modifiers}.  A typical tilde spec might
-look like @samp{%~(cut 3)~(ignore "0")y}.
-
-These are the valid modifiers:
-
-@table @code
-@item pad
-@itemx pad-left
-Pad the field to the left with spaces until it reaches the required
-length.
-
-@item pad-right
-Pad the field to the right with spaces until it reaches the required
-length.
-
-@item max
-@itemx max-left
-Cut off characters from the left until it reaches the specified length.
-
-@item max-right
-Cut off characters from the right until it reaches the specified
-length.
-
-@item cut
-@itemx cut-left
-Cut off the specified number of characters from the left.
-
-@item cut-right
-Cut off the specified number of characters from the right.
-
-@item ignore
-Return an empty string if the field is equal to the specified value.
-
-@item form
-Use the specified form as the field value when the @samp{@@} spec is
-used.
-@end table
-
-Let's take an example.  The @samp{%o} spec in the summary mode lines
-will return a date in compact ISO8601 format---@samp{19960809T230410}.
-This is quite a mouthful, so we want to shave off the century number and
-the time, leaving us with a six-character date.  That would be
-@samp{%~(cut-left 2)~(max-right 6)~(pad 6)o}.  (Cutting is done before
-maxing, and we need the padding to ensure that the date is never less
-than 6 characters to make it look nice in columns.)
-
-Ignoring is done first; then cutting; then maxing; and then as the very
-last operation, padding.
-
-If you use lots of these advanced thingies, you'll find that Gnus gets
-quite slow.  This can be helped enormously by running @kbd{M-x
-gnus-compile} when you are satisfied with the look of your lines.
-@xref{Compilation}.
-
-
-@node User-Defined Specs
-@subsection User-Defined Specs
-
-All the specs allow for inserting user defined specifiers---@samp{u}.
-The next character in the format string should be a letter.  Gnus
-will call the function @code{gnus-user-format-function-}@samp{X}, where
-@samp{X} is the letter following @samp{%u}.  The function will be passed
-a single parameter---what the parameter means depends on what buffer
-it's being called from.  The function should return a string, which will
-be inserted into the buffer just like information from any other
-specifier.  This function may also be called with dummy values, so it
-should protect against that.
-
-You can also use tilde modifiers (@pxref{Advanced Formatting} to achieve
-much the same without defining new functions.  Here's an example:
-@samp{%~(form (count-lines (point-min) (point)))@@}.  The form
-given here will be evaluated to yield the current line number, and then
-inserted.
-
-
-@node Formatting Fonts
-@subsection Formatting Fonts
-
-There are specs for highlighting, and these are shared by all the format
-variables.  Text inside the @samp{%(} and @samp{%)} specifiers will get
-the special @code{mouse-face} property set, which means that it will be
-highlighted (with @code{gnus-mouse-face}) when you put the mouse pointer
-over it.
-
-Text inside the @samp{%@{} and @samp{%@}} specifiers will have their
-normal faces set using @code{gnus-face-0}, which is @code{bold} by
-default.  If you say @samp{%1@{}, you'll get @code{gnus-face-1} instead,
-and so on.  Create as many faces as you wish.  The same goes for the
-@code{mouse-face} specs---you can say @samp{%3(hello%)} to have
-@samp{hello} mouse-highlighted with @code{gnus-mouse-face-3}.
-
-Text inside the @samp{%<} and @samp{%>} specifiers will get the special
-@code{balloon-help} property set to @code{gnus-balloon-face-0}. If you say
-@samp{%1<}, you'll get @code{gnus-balloon-face-1} and so on. The
-@code{gnus-balloon-face-*} variables should be either strings or
-symbols naming functions that return a string. Under @code{balloon-help-mode},
-when the mouse passes over text with this property set, a balloon window
-will appear and display the string. Please refer to the doc string of
-@code{balloon-help-mode} for more information on this.
-
-Here's an alternative recipe for the group buffer:
-
-@lisp
-;; Create three face types.
-(setq gnus-face-1 'bold)
-(setq gnus-face-3 'italic)
-
-;; We want the article count to be in
-;; a bold and green face.  So we create
-;; a new face called `my-green-bold'.
-(copy-face 'bold 'my-green-bold)
-;; Set the color.
-(set-face-foreground 'my-green-bold "ForestGreen")
-(setq gnus-face-2 'my-green-bold)
-
-;; Set the new & fancy format.
-(setq gnus-group-line-format
-      "%M%S%3@{%5y%@}%2[:%] %(%1@{%g%@}%)\n")
-@end lisp
-
-I'm sure you'll be able to use this scheme to create totally unreadable
-and extremely vulgar displays.  Have fun!
-
-Note that the @samp{%(} specs (and friends) do not make any sense on the
-mode-line variables.

-
-@node Windows Configuration
-@section Windows Configuration
-@cindex windows configuration
-
-No, there's nothing here about X, so be quiet.
-
-@vindex gnus-use-full-window
-If @code{gnus-use-full-window} non-@code{nil}, Gnus will delete all
-other windows and occupy the entire Emacs screen by itself.  It is
-@code{t} by default.
-
-Setting this variable to @code{nil} kinda works, but there are
-glitches.  Use at your own peril.
-
-@vindex gnus-buffer-configuration
-@code{gnus-buffer-configuration} describes how much space each Gnus
-buffer should be given.  Here's an excerpt of this variable:
-
-@lisp
-((group (vertical 1.0 (group 1.0 point)
-                      (if gnus-carpal (group-carpal 4))))
- (article (vertical 1.0 (summary 0.25 point)
-                        (article 1.0))))
-@end lisp
-
-This is an alist.  The @dfn{key} is a symbol that names some action or
-other.  For instance, when displaying the group buffer, the window
-configuration function will use @code{group} as the key.  A full list of
-possible names is listed below.
-
-The @dfn{value} (i.e., the @dfn{split}) says how much space each buffer
-should occupy.  To take the @code{article} split as an example -
-
-@lisp
-(article (vertical 1.0 (summary 0.25 point)
-                       (article 1.0)))
-@end lisp
-
-This @dfn{split} says that the summary buffer should occupy 25% of upper
-half of the screen, and that it is placed over the article buffer.  As
-you may have noticed, 100% + 25% is actually 125% (yup, I saw y'all
-reaching for that calculator there).  However, the special number
-@code{1.0} is used to signal that this buffer should soak up all the
-rest of the space available after the rest of the buffers have taken
-whatever they need.  There should be only one buffer with the @code{1.0}
-size spec per split.
-
-Point will be put in the buffer that has the optional third element
-@code{point}.  In a @code{frame} split, the last subsplit having a leaf
-split where the tag @code{frame-focus} is a member (i.e. is the third or
-fourth element in the list, depending on whether the @code{point} tag is
-present) gets focus.
-
-Here's a more complicated example:
-
-@lisp
-(article (vertical 1.0 (group 4)
-                       (summary 0.25 point)
-                       (if gnus-carpal (summary-carpal 4))
-                       (article 1.0)))
-@end lisp
-
-If the size spec is an integer instead of a floating point number,
-then that number will be used to say how many lines a buffer should
-occupy, not a percentage.
-
-If the @dfn{split} looks like something that can be @code{eval}ed (to be
-precise---if the @code{car} of the split is a function or a subr), this
-split will be @code{eval}ed.  If the result is non-@code{nil}, it will
-be used as a split.  This means that there will be three buffers if
-@code{gnus-carpal} is @code{nil}, and four buffers if @code{gnus-carpal}
-is non-@code{nil}.
-
-Not complicated enough for you?  Well, try this on for size:
-
-@lisp
-(article (horizontal 1.0
-             (vertical 0.5
-                 (group 1.0)
-                 (gnus-carpal 4))
-             (vertical 1.0
-                 (summary 0.25 point)
-                 (summary-carpal 4)
-                 (article 1.0))))
-@end lisp
-
-Whoops.  Two buffers with the mystery 100% tag.  And what's that
-@code{horizontal} thingie?
-
-If the first element in one of the split is @code{horizontal}, Gnus will
-split the window horizontally, giving you two windows side-by-side.
-Inside each of these strips you may carry on all you like in the normal
-fashion.  The number following @code{horizontal} says what percentage of
-the screen is to be given to this strip.
-
-For each split, there @emph{must} be one element that has the 100% tag.
-The splitting is never accurate, and this buffer will eat any leftover
-lines from the splits.
-
-To be slightly more formal, here's a definition of what a valid split
-may look like:
-
-@example
-split       = frame | horizontal | vertical | buffer | form
-frame       = "(frame " size *split ")"
-horizontal  = "(horizontal " size *split ")"
-vertical    = "(vertical " size *split ")"
-buffer      = "(" buffer-name " " size *[ "point" ] *[ "frame-focus"] ")"
-size        = number | frame-params
-buffer-name = group | article | summary ...
-@end example
-
-The limitations are that the @code{frame} split can only appear as the
-top-level split.  @var{form} should be an Emacs Lisp form that should
-return a valid split.  We see that each split is fully recursive, and
-may contain any number of @code{vertical} and @code{horizontal} splits.
-
-@vindex gnus-window-min-width
-@vindex gnus-window-min-height
-@cindex window height
-@cindex window width
-Finding the right sizes can be a bit complicated.  No window may be less
-than @code{gnus-window-min-height} (default 1) characters high, and all
-windows must be at least @code{gnus-window-min-width} (default 1)
-characters wide.  Gnus will try to enforce this before applying the
-splits.  If you want to use the normal Emacs window width/height limit,
-you can just set these two variables to @code{nil}.
-
-If you're not familiar with Emacs terminology, @code{horizontal} and
-@code{vertical} splits may work the opposite way of what you'd expect.
-Windows inside a @code{horizontal} split are shown side-by-side, and
-windows within a @code{vertical} split are shown above each other.
-
-@findex gnus-configure-frame
-If you want to experiment with window placement, a good tip is to call
-@code{gnus-configure-frame} directly with a split.  This is the function
-that does all the real work when splitting buffers.  Below is a pretty
-nonsensical configuration with 5 windows; two for the group buffer and
-three for the article buffer.  (I said it was nonsensical.)  If you
-@code{eval} the statement below, you can get an idea of how that would
-look straight away, without going through the normal Gnus channels.
-Play with it until you're satisfied, and then use
-@code{gnus-add-configuration} to add your new creation to the buffer
-configuration list.
-
-@lisp
-(gnus-configure-frame
- '(horizontal 1.0
-    (vertical 10
-      (group 1.0)
-      (article 0.3 point))
-    (vertical 1.0
-      (article 1.0)
-      (horizontal 4
-        (group 1.0)
-        (article 10)))))
-@end lisp
-
-You might want to have several frames as well.  No prob---just use the
-@code{frame} split:
-
-@lisp
-(gnus-configure-frame
- '(frame 1.0
-         (vertical 1.0
-                   (summary 0.25 point frame-focus)
-                   (article 1.0))
-         (vertical ((height . 5) (width . 15)
-                    (user-position . t)
-                    (left . -1) (top . 1))
-                   (picon 1.0))))
-
-@end lisp
-
-This split will result in the familiar summary/article window
-configuration in the first (or ``main'') frame, while a small additional
-frame will be created where picons will be shown.  As you can see,
-instead of the normal @code{1.0} top-level spec, each additional split
-should have a frame parameter alist as the size spec.
-@xref{Frame Parameters, , Frame Parameters, elisp, The GNU Emacs Lisp
-Reference Manual}.  Under XEmacs, a frame property list will be
-accepted, too---for instance, @code{(height 5 width 15 left -1 top 1)}
-is such a plist.
-The list of all possible keys for @code{gnus-buffer-configuration} can
-be found in its default value.
-
-Note that the @code{message} key is used for both
-@code{gnus-group-mail} and @code{gnus-summary-mail-other-window}.  If
-it is desirable to distinguish between the two, something like this
-might be used:
-
-@lisp
-(message (horizontal 1.0
-                     (vertical 1.0 (message 1.0 point))
-                     (vertical 0.24
-                               (if (buffer-live-p gnus-summary-buffer)
-                                   '(summary 0.5))
-                               (group 1.0)))))
-@end lisp
-
-One common desire for a multiple frame split is to have a separate frame
-for composing mail and news while leaving the original frame intact.  To
-accomplish that, something like the following can be done:
-
-@lisp
-(message (frame 1.0
-                (if (not (buffer-live-p gnus-summary-buffer))
-                    (car (cdr (assoc 'group gnus-buffer-configuration)))
-                  (car (cdr (assoc 'summary gnus-buffer-configuration))))
-                (vertical ((user-position . t) (top . 1) (left . 1)
-                           (name . "Message"))
-                          (message 1.0 point))))
-@end lisp
-
-@findex gnus-add-configuration
-Since the @code{gnus-buffer-configuration} variable is so long and
-complicated, there's a function you can use to ease changing the config
-of a single setting: @code{gnus-add-configuration}.  If, for instance,
-you want to change the @code{article} setting, you could say:
-
-@lisp
-(gnus-add-configuration
- '(article (vertical 1.0
-               (group 4)
-               (summary .25 point)
-               (article 1.0))))
-@end lisp
-
-You'd typically stick these @code{gnus-add-configuration} calls in your
-@file{.gnus.el} file or in some startup hook---they should be run after
-Gnus has been loaded.
-
-@vindex gnus-always-force-window-configuration
-If all windows mentioned in the configuration are already visible, Gnus
-won't change the window configuration.  If you always want to force the
-``right'' window configuration, you can set
-@code{gnus-always-force-window-configuration} to non-@code{nil}.
-
-If you're using tree displays (@pxref{Tree Display}), and the tree

-unfortunately, changing them will mean a quite significant slow-down.
-(The default values of these variables have byte-compiled functions
-associated with them, while the user-generated versions do not, of
-course.)
-
-To help with this, you can run @kbd{M-x gnus-compile} after you've
-fiddled around with the variables and feel that you're (kind of)
-satisfied.  This will result in the new specs being byte-compiled, and
-you'll get top speed again.  Gnus will save these compiled specs in the

-@code{browse}, and @code{tree}.  If the corresponding symbol is present,

-
-@cindex display-time

-@vindex gnus-mode-non-string-length
-By default, Gnus displays information on the current article in the mode
-lines of the summary and article buffers.  The information Gnus wishes
-to display (e.g. the subject of the article) is often longer than the
-mode lines, and therefore have to be cut off at some point.  The
-@code{gnus-mode-non-string-length} variable says how long the other
-elements on the line is (i.e., the non-info part).  If you put
-additional elements on the mode line (e.g. a clock), you should modify
-this variable:

-
-If this variable is @code{nil} (which is the default), the mode line
-strings won't be chopped off, and they won't be padded either.  Note

-The @code{gnus-visual} variable controls most of the Gnus-prettifying

-
-This variable can be a list of visual properties that are enabled.  The

-Other general variables that influence the look of all buffers include:
-
-@table @code
-@item gnus-mouse-face

-Those new-fangled @dfn{mouse} contraptions is very popular with the
-young, hep kids who don't want to learn the proper way to do things
-these days.  Why, I remember way back in the summer of '89, when I was
-using Emacs on a Tops 20 system.  Three hundred users on one single

-
-Right.
-
-@vindex gnus-carpal
-Well, you can make Gnus display bufferfuls of buttons you can click to

-@cindex demons
-@cindex daemons
-
-Gnus, being larger than any program ever written (allegedly), does lots
-of strange stuff that you may wish to have done while you're not
-present.  For instance, you may want it to check for new mail once in a
-while.  Or you may want it to close down all connections to all servers
-when you leave Emacs idle.  And stuff like that.
-
-Gnus will let you do stuff like that by defining various
-@dfn{handlers}.  Each handler consists of three elements:  A
-@var{function}, a @var{time}, and an @var{idle} parameter.
-
-Here's an example of a handler that closes connections when Emacs has
-been idle for thirty minutes:
-
-@lisp
-(gnus-demon-close-connections nil 30)
-@end lisp
-
-Here's a handler that scans for PGP headers every hour when Emacs is
-idle:
-
-@lisp
-(gnus-demon-scan-pgp 60 t)
-@end lisp
-
-This @var{time} parameter and than @var{idle} parameter work together
-in a strange, but wonderful fashion.  Basically, if @var{idle} is
-@code{nil}, then the function will be called every @var{time} minutes.
-
-If @var{idle} is @code{t}, then the function will be called after
-@var{time} minutes only if Emacs is idle.  So if Emacs is never idle,
-the function will never be called.  But once Emacs goes idle, the
-function will be called every @var{time} minutes.
-
-If @var{idle} is a number and @var{time} is a number, the function will
-be called every @var{time} minutes only when Emacs has been idle for
-@var{idle} minutes.
-
-If @var{idle} is a number and @var{time} is @code{nil}, the function
-will be called once every time Emacs has been idle for @var{idle}
-minutes.
-
-And if @var{time} is a string, it should look like @samp{07:31}, and
-the function will then be called once every day somewhere near that
-time.  Modified by the @var{idle} parameter, of course.
-
-@vindex gnus-demon-timestep
-(When I say ``minute'' here, I really mean @code{gnus-demon-timestep}
-seconds.  This is 60 by default.  If you change that variable,
-all the timings in the handlers will be affected.)
-
-So, if you want to add a handler, you could put something like this in
-your @file{.gnus} file:
-
-@findex gnus-demon-add-handler
-@lisp
-(gnus-demon-add-handler 'gnus-demon-close-connections 30 t)
-@end lisp
-
-@findex gnus-demon-add-nocem
-@findex gnus-demon-add-scanmail
-@findex gnus-demon-add-rescan
-@findex gnus-demon-add-scan-timestamps
-@findex gnus-demon-add-disconnection
-Some ready-made functions to do this have been created:
-@code{gnus-demon-add-nocem}, @code{gnus-demon-add-disconnection},
-@code{gnus-demon-add-nntp-close-connection},
-@code{gnus-demon-add-scan-timestamps}, @code{gnus-demon-add-rescan}, and
-@code{gnus-demon-add-scanmail}.  Just put those functions in your
-@file{.gnus} if you want those abilities.
-
-@findex gnus-demon-init
-@findex gnus-demon-cancel
-@vindex gnus-demon-handlers
-If you add handlers to @code{gnus-demon-handlers} directly, you should
-run @code{gnus-demon-init} to make the changes take hold.  To cancel all
-daemons, you can use the @code{gnus-demon-cancel} function.
-
-Note that adding daemons can be pretty naughty if you over do it.  Adding
-functions that scan all news and mail from all servers every two seconds
-is a sure-fire way of getting booted off any respectable system.  So
-behave.

-@node NoCeM
-@section NoCeM
-@cindex nocem
-@cindex spam
-
-@dfn{Spamming} is posting the same article lots and lots of times.
-Spamming is bad.  Spamming is evil.
-
-Spamming is usually canceled within a day or so by various anti-spamming
-agencies.  These agencies usually also send out @dfn{NoCeM} messages.
-NoCeM is pronounced ``no see-'em'', and means what the name
-implies---these are messages that make the offending articles, like, go
-away.
-
-What use are these NoCeM messages if the articles are canceled anyway?
-Some sites do not honor cancel messages and some sites just honor cancels
-from a select few people.  Then you may wish to make use of the NoCeM
-messages, which are distributed in the @samp{alt.nocem.misc} newsgroup.
-
-Gnus can read and parse the messages in this group automatically, and
-this will make spam disappear.
-
-There are some variables to customize, of course:
-
-@table @code
-@item gnus-use-nocem
-@vindex gnus-use-nocem
-Set this variable to @code{t} to set the ball rolling.  It is @code{nil}
-by default.
-
-@item gnus-nocem-groups
-@vindex gnus-nocem-groups
-Gnus will look for NoCeM messages in the groups in this list.  The
-default is @code{("news.lists.filters" "news.admin.net-abuse.bulletins"
-"alt.nocem.misc" "news.admin.net-abuse.announce")}.
-
-@item gnus-nocem-issuers
-@vindex gnus-nocem-issuers
-There are many people issuing NoCeM messages.  This list says what
-people you want to listen to.  The default is @code{("Automoose-1"
-"rbraver@@ohww.norman.ok.us" "clewis@@ferret.ocunix.on.ca"
-"jem@@xpat.com" "snowhare@@xmission.com" "red@@redpoll.mrfs.oh.us
-(Richard E. Depew)")}; fine, upstanding citizens all of them.
-
-Known despammers that you can put in this list include:
-
-@table @samp
-@item clewis@@ferret.ocunix.on.ca;
-@cindex Chris Lewis
-Chris Lewis---Major Canadian despammer who has probably canceled more
-usenet abuse than anybody else.
-
-@item Automoose-1
-@cindex CancelMoose[tm]
-The CancelMoose[tm] on autopilot.  The CancelMoose[tm] is reputed to be
-Norwegian, and was the person(s) who invented NoCeM.
-
-@item jem@@xpat.com;
-@cindex Jem
-John Milburn---despammer located in Korea who is getting very busy these
-days.
-
-@item red@@redpoll.mrfs.oh.us (Richard E. Depew)
-Richard E. Depew---lone American despammer.  He mostly cancels binary
-postings to non-binary groups and removes spews (regurgitated articles).
-@end table
-
-You do not have to heed NoCeM messages from all these people---just the
-ones you want to listen to.  You also don't have to accept all NoCeM
-messages from the people you like.  Each NoCeM message has a @dfn{type}
-header that gives the message a (more or less, usually less) rigorous
-definition.  Common types are @samp{spam}, @samp{spew}, @samp{mmf},
-@samp{binary}, and @samp{troll}.  To specify this, you have to use
-@code{(@var{issuer} @var{conditions} @dots{})} elements in the list.
-Each condition is either a string (which is a regexp that matches types
-you want to use) or a list on the form @code{(not @var{string})}, where
-@var{string} is a regexp that matches types you don't want to use.
-
-For instance, if you want all NoCeM messages from Chris Lewis except his
-@samp{troll} messages, you'd say:
-
-@lisp
-("clewis@@ferret.ocunix.on.ca" ".*" (not "troll"))
-@end lisp
-
-On the other hand, if you just want nothing but his @samp{spam} and
-@samp{spew} messages, you'd say:
-
-@lisp
-("clewis@@ferret.ocunix.on.ca" (not ".*") "spew" "spam")
-@end lisp
-
-The specs are applied left-to-right.
-
-
-@item gnus-nocem-verifyer
-@vindex gnus-nocem-verifyer
-@findex mc-verify
-This should be a function for verifying that the NoCeM issuer is who she
-says she is.  The default is @code{mc-verify}, which is a Mailcrypt
-function.  If this is too slow and you don't care for verification
-(which may be dangerous), you can set this variable to @code{nil}.
-
-If you want signed NoCeM messages to be verified and unsigned messages
-not to be verified (but used anyway), you could do something like:
-
-@lisp
-(setq gnus-nocem-verifyer 'my-gnus-mc-verify)
-
-(defun my-gnus-mc-verify ()
-  (not (eq 'forged
-           (ignore-errors
-             (if (mc-verify)
-                 t
-               'forged)))))
-@end lisp
-
-This might be dangerous, though.
-
-@item gnus-nocem-directory
-@vindex gnus-nocem-directory
-This is where Gnus will store its NoCeM cache files.  The default is
-@file{~/News/NoCeM/}.
-
-@item gnus-nocem-expiry-wait
-@vindex gnus-nocem-expiry-wait
-The number of days before removing old NoCeM entries from the cache.
-The default is 15.  If you make it shorter Gnus will be faster, but you
-might then see old spam.
-
-@end table
-
-Using NoCeM could potentially be a memory hog.  If you have many living
-(i. e., subscribed or unsubscribed groups), your Emacs process will grow
-big.  If this is a problem, you should kill off all (or most) of your
-unsubscribed groups (@pxref{Subscription Commands}).
-
-
-@node Undo
-@section Undo
-@cindex undo
-
-It is very useful to be able to undo actions one has done.  In normal
-Emacs buffers, it's easy enough---you just push the @code{undo} button.
-In Gnus buffers, however, it isn't that simple.
-
-The things Gnus displays in its buffer is of no value whatsoever to
-Gnus---it's all just data designed to look nice to the user.
-Killing a group in the group buffer with @kbd{C-k} makes the line
-disappear, but that's just a side-effect of the real action---the
-removal of the group in question from the internal Gnus structures.
-Undoing something like that can't be done by the normal Emacs
-@code{undo} function.
-
-Gnus tries to remedy this somewhat by keeping track of what the user
-does and coming up with actions that would reverse the actions the user
-takes.  When the user then presses the @code{undo} key, Gnus will run
-the code to reverse the previous action, or the previous actions.
-However, not all actions are easily reversible, so Gnus currently offers
-a few key functions to be undoable.  These include killing groups,
-yanking groups, and changing the list of read articles of groups.
-That's it, really.  More functions may be added in the future, but each
-added function means an increase in data to be stored, so Gnus will
-never be totally undoable.
-
-@findex gnus-undo-mode
-@vindex gnus-use-undo
-@findex gnus-undo
-The undoability is provided by the @code{gnus-undo-mode} minor mode.  It
-is used if @code{gnus-use-undo} is non-@code{nil}, which is the
-default.  The @kbd{M-C-_} key performs the @code{gnus-undo} command
-command, which should feel kinda like the normal Emacs @code{undo}
-command.

-
-@item
-You enter that group once in a while and post articles using the @kbd{e}
-(edit-and-post) or @kbd{s} (just send unedited) commands.
-
-@item
-If, while reading the @samp{rec.zoofle} newsgroup, you happen upon some
-articles that weren't approved by you, you can cancel them with the
-@kbd{c} command.

-@dfn{Picons} is short for ``personal icons''.  They're small,
-constrained images used to represent users and domains on the net,
-organized into databases so that the appropriate image for a given
-e-mail address can be found.  Besides users and domains, there are picon

-the like---to pictures and displays those instead of the text smiley
-faces.  The conversion is controlled by a list of regexps that matches
-text and maps that to file names.
-
-@vindex smiley-nosey-regexp-alist
-@vindex smiley-deformed-regexp-alist
-Smiley supplies two example conversion alists by default:
-@code{smiley-deformed-regexp-alist} (which matches @samp{:)}, @samp{:(}
-and so on), and @code{smiley-nosey-regexp-alist} (which matches
-@samp{:-)}, @samp{:-(} and so on).
-
-The alist used is specified by the @code{smiley-regexp-alist} variable,
-which defaults to the value of @code{smiley-deformed-regexp-alist}.
-
-The first item in each element is the regexp to be matched; the second
-element is the regexp match group that is to be replaced by the picture;
-and the third element is the name of the file to be displayed.
-
-The following variables customize where Smiley will look for these
-files, as well as the color to be used and stuff:
-

-
-@item smiley-data-directory
-@vindex smiley-data-directory

-Gnus provides @dfn{fuzzy matching} of @code{Subject} lines when doing
-things like scoring, thread gathering and thread comparison.
-
-As opposed to regular expression matching, fuzzy matching is very fuzzy.
-It's so fuzzy that there's not even a definition of what @dfn{fuzziness}
-means, and the implementation has changed over time.
-
-Basically, it tries to remove all noise from lines before comparing.
-@samp{Re: }, parenthetical remarks, white space, and so on, are filtered
-out of the strings before comparing the results.  This often leads to
-adequate results---even when faced with strings generated by text
-manglers masquerading as newsreaders.

-@node Thwarting Email Spam
-@section Thwarting Email Spam
-@cindex email spam
-@cindex spam
-@cindex UCE
-@cindex unsolicited commercial email
-
-In these last days of the Usenet, commercial vultures are hanging about
-and grepping through news like crazy to find email addresses they can
-foist off their scams and products to.  As a reaction to this, many
-people have started putting nonsense addresses into their @code{From}
-lines.  I think this is counterproductive---it makes it difficult for
-people to send you legitimate mail in response to things you write, as
-well as making it difficult to see who wrote what.  This rewriting may
-perhaps be a bigger menace than the unsolicited commercial email itself
-in the end.
-
-The biggest problem I have with email spam is that it comes in under
-false pretenses.  I press @kbd{g} and Gnus merrily informs me that I
-have 10 new emails.  I say ``Golly gee!  Happy is me!'' and select the
-mail group, only to find two pyramid schemes, seven advertisements
-(``New!  Miracle tonic for growing full, lustrous hair on your toes!'')
-and one mail asking me to repent and find some god.
-
-This is annoying.
-
-The way to deal with this is having Gnus split out all spam into a
-@samp{spam} mail group (@pxref{Splitting Mail}).
-
-First, pick one (1) valid mail address that you can be reached at, and
-put it in your @code{From} header of all your news articles.  (I've
-chosen @samp{larsi@@trym.ifi.uio.no}, but for many addresses on the form
-@samp{larsi+usenet@@ifi.uio.no} will be a better choice.  Ask your
-sysadm whether your sendmail installation accepts keywords in the local
-part of the mail address.)
-
-@lisp
-(setq message-default-news-headers
-      "From: Lars Magne Ingebrigtsen <larsi@@trym.ifi.uio.no>\n")
-@end lisp
-
-Then put the following split rule in @code{nnmail-split-fancy}
-(@pxref{Fancy Mail Splitting}):
-
-@lisp
-(
- ...
- (to "larsi@@trym.ifi.uio.no"
-      (| ("subject" "re:.*" "misc")
-         ("references" ".*@@.*" "misc")
-         "spam"))
- ...
-)
-@end lisp
-
-This says that all mail to this address is suspect, but if it has a
-@code{Subject} that starts with a @samp{Re:} or has a @code{References}
-header, it's probably ok.  All the rest goes to the @samp{spam} group.
-(This idea probably comes from Tim Pierce.)
-
-In addition, many mail spammers talk directly to your @code{smtp} server
-and do not include your email address explicitly in the @code{To}
-header.  Why they do this is unknown---perhaps it's to thwart this
-thwarting scheme?  In any case, this is trivial to deal with---you just
-put anything not addressed to you in the @samp{spam} group by ending
-your fancy split rule in this way:
-
-@lisp
-(
- ...
- (to "larsi" "misc")
- "spam")
-@end lisp
-
-In my experience, this will sort virtually everything into the right
-group.  You still have to check the @samp{spam} group from time to time to
-check for legitimate mail, though.  If you feel like being a good net
-citizen, you can even send off complaints to the proper authorities on
-each unsolicited commercial email---at your leisure.
-
-If you are also a lazy net citizen, you will probably prefer complaining
-automatically with the @file{gnus-junk.el} package, available FOR FREE
-at @* @file{<URL:http://stud2.tuwien.ac.at/~e9426626/gnus-junk.html>}.
-Since most e-mail spam is sent automatically, this may reconcile the
-cosmic balance somewhat.
-
-This works for me.  It allows people an easy way to contact me (they can
-just press @kbd{r} in the usual way), and I'm not bothered at all with
-spam.  It's a win-win situation.  Forging @code{From} headers to point
-to non-existent domains is yucky, in my opinion.

-@section History
-
-@cindex history
-@sc{gnus} was written by Masanobu @sc{Umeda}.  When autumn crept up in
-'94, Lars Magne Ingebrigtsen grew bored and decided to rewrite Gnus.
-
-If you want to investigate the person responsible for this outrage, you
-can point your (feh!) web browser to
-@file{http://www.stud.ifi.uio.no/~larsi/}.  This is also the primary
-distribution point for the new and spiffy versions of Gnus, and is known
-as The Site That Destroys Newsrcs And Drives People Mad.
-
-During the first extended alpha period of development, the new Gnus was
-called ``(ding) Gnus''.  @dfn{(ding)} is, of course, short for
-@dfn{ding is not Gnus}, which is a total and utter lie, but who cares?
-(Besides, the ``Gnus'' in this abbreviation should probably be
-pronounced ``news'' as @sc{Umeda} intended, which makes it a more
-appropriate name, don't you think?)
-
-In any case, after spending all that energy on coming up with a new and
-spunky name, we decided that the name was @emph{too} spunky, so we
-renamed it back again to ``Gnus''.  But in mixed case.  ``Gnus'' vs.
-``@sc{gnus}''.  New vs. old.
-
-The first ``proper'' release of Gnus 5 was done in November 1995 when it
-was included in the Emacs 19.30 distribution (132 (ding) Gnus releases
-plus 15 Gnus 5.0 releases).
-
-In May 1996 the next Gnus generation (aka. ``September Gnus'' (after 99
-releases)) was released under the name ``Gnus 5.2'' (40 releases).
-
-On July 28th 1996 work on Red Gnus was begun, and it was released on
-January 25th 1997 (after 84 releases) as ``Gnus 5.4'' (67 releases).
-
-On September 13th 1997, Quassia Gnus was started and lasted 37
-releases.  If was released as ``Gnus 5.6 on March 8th 1998.
-
-If you happen upon a version of Gnus that has a prefixed name --
-``(ding) Gnus'', ``September Gnus'', ``Red Gnus'', ``Quassia Gnus'' --
-don't panic.  Don't let it know that you're frightened.  Back away.
-Slowly.  Whatever you do, don't run.  Walk away, calmly, until you're
-out of its reach.  Find a proper released version of Gnus and snuggle up
-to that instead.

-
-What's the point of Gnus?
-
-I want to provide a ``rad'', ``happening'', ``way cool'' and ``hep''
-newsreader, that lets you do anything you can think of.  That was my
-original motivation, but while working on Gnus, it has become clear to
-me that this generation of newsreaders really belong in the stone age.
-Newsreaders haven't developed much since the infancy of the net.  If the
-volume continues to rise with the current rate of increase, all current
-newsreaders will be pretty much useless.  How do you deal with
-newsgroups that have thousands of new articles each day?  How do you
-keep track of millions of people who post?
-
-Gnus offers no real solutions to these questions, but I would very much
-like to see Gnus being used as a testing ground for new methods of
-reading and fetching news.  Expanding on @sc{Umeda}-san's wise decision
-to separate the newsreader from the backends, Gnus now offers a simple
-interface for anybody who wants to write new backends for fetching mail
-and news from different sources.  I have added hooks for customizations
-everywhere I could imagine it being useful.  By doing so, I'm inviting
-every one of you to explore and invent.

-May Gnus never be complete. @kbd{C-u 100 M-x all-hail-emacs} and

-@node Compatibility
-@subsection Compatibility
-
-@cindex compatibility
-Gnus was designed to be fully compatible with @sc{gnus}.  Almost all key
-bindings have been kept.  More key bindings have been added, of course,
-but only in one or two obscure cases have old bindings been changed.
-
-Our motto is:
-@quotation
-@cartouche
-@center In a cloud bones of steel.
-@end cartouche
-@end quotation
-
-All commands have kept their names.  Some internal functions have changed
-their names.
-
-The @code{gnus-uu} package has changed drastically. @xref{Decoding
-Articles}.
-
-One major compatibility question is the presence of several summary
-buffers.  All variables relevant while reading a group are
-buffer-local to the summary buffer they belong in.  Although many
-important variables have their values copied into their global
-counterparts whenever a command is executed in the summary buffer, this
-change might lead to incorrect values being used unless you are careful.
-
-All code that relies on knowledge of @sc{gnus} internals will probably
-fail.  To take two examples: Sorting @code{gnus-newsrc-alist} (or
-changing it in any way, as a matter of fact) is strictly verboten.  Gnus
-maintains a hash table that points to the entries in this alist (which
-speeds up many functions), and changing the alist directly will lead to
-peculiar results.
-
-@cindex hilit19
-@cindex highlighting
-Old hilit19 code does not work at all.  In fact, you should probably
-remove all hilit code from all Gnus hooks
-(@code{gnus-group-prepare-hook} and @code{gnus-summary-prepare-hook}).
-Gnus provides various integrated functions for highlighting.  These are
-faster and more accurate.  To make life easier for everybody, Gnus will
-by default remove all hilit calls from all hilit hooks.  Uncleanliness!
-Away!
-
-Packages like @code{expire-kill} will no longer work.  As a matter of
-fact, you should probably remove all old @sc{gnus} packages (and other
-code) when you start using Gnus.  More likely than not, Gnus already
-does what you have written code to make @sc{gnus} do.  (Snicker.)
-
-Even though old methods of doing things are still supported, only the
-new methods are documented in this manual.  If you detect a new method of
-doing something while reading this manual, that does not mean you have
-to stop doing it the old way.

-@node Gnus Development
-@subsection Gnus Development
-
-Gnus is developed in a two-phased cycle.  The first phase involves much
-discussion on the @samp{ding@@gnus.org} mailing list, where people
-propose changes and new features, post patches and new backends.  This
-phase is called the @dfn{alpha} phase, since the Gnusae released in this
-phase are @dfn{alpha releases}, or (perhaps more commonly in other
-circles) @dfn{snapshots}.  During this phase, Gnus is assumed to be
-unstable and should not be used by casual users.  Gnus alpha releases
-have names like ``Red Gnus'' and ``Quassia Gnus''.
-
-After futzing around for 50-100 alpha releases, Gnus is declared
-@dfn{frozen}, and only bug fixes are applied.  Gnus loses the prefix,
-and is called things like ``Gnus 5.6.32'' instead.  Normal people are
-supposed to be able to use these, and these are mostly discussed on the
-@samp{gnu.emacs.gnus} newsgroup.
-
-@cindex Incoming*
-@vindex nnmail-delete-incoming
-Some variable defaults differ between alpha Gnusae and released Gnusae.
-In particular, @code{nnmail-delete-incoming} defaults to @code{nil} in
-alpha Gnusae and @code{t} in released Gnusae.  This is to prevent
-lossage of mail if an alpha release hiccups while handling the mail.
-
-The division of discussion between the ding mailing list and the Gnus
-newsgroup is not purely based on publicity concerns.  It's true that
-having people write about the horrible things that an alpha Gnus release
-can do (sometimes) in a public forum may scare people off, but more
-importantly, talking about new experimental features that have been
-introduced may confuse casual users.  New features are frequently
-introduced, fiddled with, and judged to be found wanting, and then
-either discarded or totally rewritten.  People reading the mailing list
-usually keep up with these rapid changes, whille people on the newsgroup
-can't be assumed to do so.

-@item
- I like the option for trying to retrieve the FAQ for a group and I was
-thinking it would be great if for those newsgroups that had archives
-you could also try to read the archive for that group.  Part of the
-problem is that archives are spread all over the net, unlike FAQs.
-What would be best I suppose is to find the one closest to your site.
-
-In any case, there is a list of general news group archives at @*

-@item
- tanken var at når du bruker `gnus-startup-file' som prefix (FOO) til å lete
-opp en fil FOO-SERVER, FOO-SERVER.el, FOO-SERVER.eld, kan du la den være en

-LMI> Well, nnbabyl could alter the group info to heed labels like
-LMI> answered and read, I guess.
-
-It could also keep them updated (the same for the Status: header of
-unix mbox files).
-
-They could be used like this:
-
-
-@example
-`M l <name> RET' add label <name> to current message.
-`M u <name> RET' remove label <name> from current message.
-`/ l <expr> RET' limit summary buffer according to <expr>.
-
-<expr> would be a boolean expression on the labels, e.g.
-
-`/ l bug & !fixed RET'
-@end example
-
-would show all the messages which are labeled `bug' but not labeled
-`fixed'.
-
-One could also imagine the labels being used for highlighting, or
-affect the summary line format.

-I'd like a gnus-find-file which work like find file, except that it
-would recognize things that looks like messages or folders:
-
-- If it is a directory containing numbered files, create an nndir
-summary buffer.
-
-- For other directories, create a nneething summary buffer.
-
-- For files matching "\\`From ", create a nndoc/mbox summary.
-
-- For files matching "\\`BABYL OPTIONS:", create a nndoc/baby summary.
-
-- For files matching "\\`[^ \t\n]+:", create an *Article* buffer.
-
-- For other files, just find them normally.
-
-I'd like `nneething' to use this function, so it would work on a
-directory potentially containing mboxes or babyl files.

-@item
-Currently, I get prompted:
-
-decend into sci?
-- type y
-decend into sci.something ?
-- type n
-decend into ucd?
-
-The problem above is that since there is really only one subsection of
-science, shouldn't it prompt you for only descending sci.something?  If
-there was a sci.somethingelse group or section, then it should prompt
-for sci? first the sci.something? then sci.somethingelse?...
-
-@item
-Ja, det burde være en måte å si slikt.  Kanskje en ny variabel?
-`gnus-use-few-score-files'?  Så kunne score-regler legges til den
-"mest" lokale score-fila.  F. eks. ville no-gruppene betjenes av
-"no.all.SCORE", osv.
-
-@item
-What i want is for Gnus to treat any sequence or combination of the following
-as a single spoiler warning and hide it all, replacing it with a "Next Page"
-button:
-
-
-^L's
-
-more than n blank lines
-
-more than m identical lines
-(which should be replaced with button to show them)
-
-any whitespace surrounding any of the above
-
-
-@item
-Well, we could allow a new value to `gnus-thread-ignore-subject' --
-`spaces', or something.  (We could even default to that.)  And then
-subjects that differ in white space only could be considered the
-"same" subject for threading purposes.
-
-@item
-Modes to preprocess the contents (e.g. jka-compr) use the second form
-"(REGEXP FUNCTION NON-NIL)" while ordinary modes (e.g. tex) use the first
-form "(REGEXP . FUNCTION)", so you could use it to distinguish between
-those two types of modes. (auto-modes-alist, insert-file-contents-literally.)

-My precise need here would have been to limit files to Incoming*.
-One could think of some `nneething-only-files' variable, but I guess

-A more useful approach would be to, in response to the `G D' prompt, be

-  Take a look at w3-menu.el in the Emacs-W3 distribution - this works out

-
-  So for gnus-summary-menus, I would set to '(sort mark dispose ...)

-
-@item news
-@cindex news
-This is what you are supposed to use this thing for---reading news.
-News is generally fetched from a nearby @sc{nntp} server, and is
-generally publicly available to everybody.  If you post news, the entire
-world is likely to read just what you have written, and they'll all
-snigger mischievously.  Behind your back.
-
-@item mail
-@cindex mail
-Everything that's delivered to you personally is mail.  Some news/mail
-readers (like Gnus) blur the distinction between mail and news, but
-there is a difference.  Mail is private.  News is public.  Mailing is
-not posting, and replying is not following up.
-
-@item reply
-@cindex reply
-Send a mail to the person who has written what you are reading.
-
-@item follow up
-@cindex follow up
-Post an article to the current newsgroup responding to the article you
-are reading.
-
-@item backend
-@cindex backend
-Gnus gets fed articles from a number of backends, both news and mail
-backends.  Gnus does not handle the underlying media, so to speak---this
-is all done by the backends.
-
-@item native
-@cindex native
-Gnus will always use one method (and backend) as the @dfn{native}, or
-default, way of getting news.
-
-@item foreign
-@cindex foreign
-You can also have any number of foreign groups active at the same time.
-These are groups that use non-native non-secondary backends for getting
-news.
-
-@item secondary
-@cindex secondary
-Secondary backends are somewhere half-way between being native and being
-foreign, but they mostly act like they are native.
-
-@item article
-@cindex article
-A message that has been posted as news.
-
-@item mail message
-@cindex mail message
-A message that has been mailed.
-
-@item message
-@cindex message
-A mail message or news article
-
-@item head
-@cindex head
-The top part of a message, where administrative information (etc.) is
-put.
-
-@item body
-@cindex body
-The rest of an article.  Everything not in the head is in the
-body.
-
-@item header
-@cindex header
-A line from the head of an article.
-
-@item headers
-@cindex headers
-A collection of such lines, or a collection of heads.  Or even a
-collection of @sc{nov} lines.
-
-@item @sc{nov}
-@cindex nov
-When Gnus enters a group, it asks the backend for the headers of all
-unread articles in the group.  Most servers support the News OverView
-format, which is more compact and much faster to read and parse than the
-normal @sc{head} format.
-
-@item level
-@cindex levels
-Each group is subscribed at some @dfn{level} or other (1-9).  The ones
-that have a lower level are ``more'' subscribed than the groups with a
-higher level.  In fact, groups on levels 1-5 are considered
-@dfn{subscribed}; 6-7 are @dfn{unsubscribed}; 8 are @dfn{zombies}; and 9
-are @dfn{killed}.  Commands for listing groups and scanning for new
-articles will all use the numeric prefix as @dfn{working level}.
-
-@item killed groups
-@cindex killed groups
-No information on killed groups is stored or updated, which makes killed
-groups much easier to handle than subscribed groups.
-
-@item zombie groups
-@cindex zombie groups
-Just like killed groups, only slightly less dead.
-
-@item active file
-@cindex active file
-The news server has to keep track of what articles it carries, and what
-groups exist.  All this information in stored in the active file, which
-is rather large, as you might surmise.
-
-@item bogus groups
-@cindex bogus groups
-A group that exists in the @file{.newsrc} file, but isn't known to the
-server (i.e.,  it isn't in the active file), is a @emph{bogus group}.
-This means that the group probably doesn't exist (any more).
-
-@item activating
-@cindex activating groups
-The act of asking the server for info on a group and computing the
-number of unread articles is called @dfn{activating the group}.
-Un-activated groups are listed with @samp{*} in the group buffer.
-
-@item server
-@cindex server
-A machine one can connect to and get news (or mail) from.
-
-@item select method
-@cindex select method
-A structure that specifies the backend, the server and the virtual
-server settings.
-
-@item virtual server
-@cindex virtual server
-A named select method.  Since a select method defines all there is to
-know about connecting to a (physical) server, taking the thing as a
-whole is a virtual server.
-
-@item washing
-@cindex washing
-Taking a buffer and running it through a filter of some sort.  The
-result will (more often than not) be cleaner and more pleasing than the
-original.
-
-@item ephemeral groups
-@cindex ephemeral groups
-Most groups store data on what articles you have read.  @dfn{Ephemeral}
-groups are groups that will have no data stored---when you exit the
-group, it'll disappear into the aether.
-
-@item solid groups
-@cindex solid groups
-This is the opposite of ephemeral groups.  All groups listed in the
-group buffer are solid groups.
-
-@item sparse articles
-@cindex sparse articles
-These are article placeholders shown in the summary buffer when
-@code{gnus-build-sparse-threads} has been switched on.
-
-@item threading
-@cindex threading
-To put responses to articles directly after the articles they respond
-to---in a hierarchical fashion.
-
-@item root
-@cindex root
-@cindex thread root
-The first article in a thread is the root.  It is the ancestor of all
-articles in the thread.
-
-@item parent
-@cindex parent
-An article that has responses.
-
-@item child
-@cindex child
-An article that responds to a different article---its parent.

-@node Backend Interface
-@subsection Backend Interface
-
-Gnus doesn't know anything about @sc{nntp}, spools, mail or virtual
-groups.  It only knows how to talk to @dfn{virtual servers}.  A virtual
-server is a @dfn{backend} and some @dfn{backend variables}.  As examples
-of the first, we have @code{nntp}, @code{nnspool} and @code{nnmbox}.  As
-examples of the latter we have @code{nntp-port-number} and
-@code{nnmbox-directory}.
-
-When Gnus asks for information from a backend---say @code{nntp}---on
-something, it will normally include a virtual server name in the
-function parameters.  (If not, the backend should use the ``current''
-virtual server.)  For instance, @code{nntp-request-list} takes a virtual
-server as its only (optional) parameter.  If this virtual server hasn't
-been opened, the function should fail.
-
-Note that a virtual server name has no relation to some physical server
-name.  Take this example:
-
-@lisp
-(nntp "odd-one"
-      (nntp-address "ifi.uio.no")
-      (nntp-port-number 4324))
-@end lisp
-
-Here the virtual server name is @samp{odd-one} while the name of
-the physical server is @samp{ifi.uio.no}.
-
-The backends should be able to switch between several virtual servers.
-The standard backends implement this by keeping an alist of virtual
-server environments that they pull down/push up when needed.
-
-There are two groups of interface functions: @dfn{required functions},
-which must be present, and @dfn{optional functions}, which Gnus will
-always check for presence before attempting to call 'em.
-
-All these functions are expected to return data in the buffer
-@code{nntp-server-buffer} (@samp{ *nntpd*}), which is somewhat
-unfortunately named, but we'll have to live with it.  When I talk about
-@dfn{resulting data}, I always refer to the data in that buffer.  When I
-talk about @dfn{return value}, I talk about the function value returned by
-the function call.  Functions that fail should return @code{nil} as the
-return value.
-
-Some backends could be said to be @dfn{server-forming} backends, and
-some might be said not to be.  The latter are backends that generally
-only operate on one group at a time, and have no concept of ``server''
--- they have a group, and they deliver info on that group and nothing
-more.
-
-In the examples and definitions I will refer to the imaginary backend
-@code{nnchoke}.

-@subsubsection Required Backend Functions
-
-@table @code
-
-@item (nnchoke-retrieve-headers ARTICLES &optional GROUP SERVER FETCH-OLD)
-
-@var{articles} is either a range of article numbers or a list of
-@code{Message-ID}s.  Current backends do not fully support either---only
-sequences (lists) of article numbers, and most backends do not support
-retrieval of @code{Message-ID}s.  But they should try for both.
-
-The result data should either be HEADs or NOV lines, and the result
-value should either be @code{headers} or @code{nov} to reflect this.
-This might later be expanded to @code{various}, which will be a mixture
-of HEADs and NOV lines, but this is currently not supported by Gnus.
-
-If @var{fetch-old} is non-@code{nil} it says to try fetching "extra
-headers", in some meaning of the word.  This is generally done by
-fetching (at most) @var{fetch-old} extra headers less than the smallest
-article number in @code{articles}, and filling the gaps as well.  The
-presence of this parameter can be ignored if the backend finds it
-cumbersome to follow the request.  If this is non-@code{nil} and not a
-number, do maximum fetches.
-
-Here's an example HEAD:
-
-@example
-221 1056 Article retrieved.
-Path: ifi.uio.no!sturles
-From: sturles@@ifi.uio.no (Sturle Sunde)
-Newsgroups: ifi.discussion
-Subject: Re: Something very droll
-Date: 27 Oct 1994 14:02:57 +0100
-Organization: Dept. of Informatics, University of Oslo, Norway
-Lines: 26
-Message-ID: <38o8e1$a0o@@holmenkollen.ifi.uio.no>
-References: <38jdmq$4qu@@visbur.ifi.uio.no>
-NNTP-Posting-Host: holmenkollen.ifi.uio.no
-.
-@end example
-
-So a @code{headers} return value would imply that there's a number of
-these in the data buffer.
-
-Here's a BNF definition of such a buffer:
-
-@example
-headers        = *head
-head           = error / valid-head
-error-message  = [ "4" / "5" ] 2number " " <error message> eol
-valid-head     = valid-message *header "." eol
-valid-message  = "221 " <number> " Article retrieved." eol
-header         = <text> eol
-@end example
-
-If the return value is @code{nov}, the data buffer should contain
-@dfn{network overview database} lines.  These are basically fields
-separated by tabs.
-
-@example
-nov-buffer = *nov-line
-nov-line   = 8*9 [ field <TAB> ] eol
-field      = <text except TAB>
-@end example
-
-For a closer look at what should be in those fields,
-@pxref{Headers}.
-
-
-@item (nnchoke-open-server SERVER &optional DEFINITIONS)
-
-@var{server} is here the virtual server name.  @var{definitions} is a
-list of @code{(VARIABLE VALUE)} pairs that define this virtual server.
-
-If the server can't be opened, no error should be signaled.  The backend
-may then choose to refuse further attempts at connecting to this
-server.  In fact, it should do so.
-
-If the server is opened already, this function should return a
-non-@code{nil} value.  There should be no data returned.
-
-
-@item (nnchoke-close-server &optional SERVER)
-
-Close connection to @var{server} and free all resources connected
-to it.  Return @code{nil} if the server couldn't be closed for some
-reason.
-
-There should be no data returned.
-
-
-@item (nnchoke-request-close)
-
-Close connection to all servers and free all resources that the backend
-have reserved.  All buffers that have been created by that backend
-should be killed.  (Not the @code{nntp-server-buffer}, though.)  This
-function is generally only called when Gnus is shutting down.
-
-There should be no data returned.
-
-
-@item (nnchoke-server-opened &optional SERVER)
-
-If @var{server} is the current virtual server, and the connection to the
-physical server is alive, then this function should return a
-non-@code{nil} vlue.  This function should under no circumstances
-attempt to reconnect to a server we have lost connection to.
-
-There should be no data returned.
-
-
-@item (nnchoke-status-message &optional SERVER)
-
-This function should return the last error message from @var{server}.
-
-There should be no data returned.
-
-
-@item (nnchoke-request-article ARTICLE &optional GROUP SERVER TO-BUFFER)
-
-The result data from this function should be the article specified by
-@var{article}.  This might either be a @code{Message-ID} or a number.
-It is optional whether to implement retrieval by @code{Message-ID}, but
-it would be nice if that were possible.
-
-If @var{to-buffer} is non-@code{nil}, the result data should be returned
-in this buffer instead of the normal data buffer.  This is to make it
-possible to avoid copying large amounts of data from one buffer to
-another, while Gnus mainly requests articles to be inserted directly
-into its article buffer.
-
-If it is at all possible, this function should return a cons cell where
-the @code{car} is the group name the article was fetched from, and the @code{cdr} is
-the article number.  This will enable Gnus to find out what the real
-group and article numbers are when fetching articles by
-@code{Message-ID}.  If this isn't possible, @code{t} should be returned
-on successful article retrieval.
-
-
-@item (nnchoke-request-group GROUP &optional SERVER FAST)
-
-Get data on @var{group}.  This function also has the side effect of
-making @var{group} the current group.
-
-If @var{fast}, don't bother to return useful data, just make @var{group}
-the current group.
-
-Here's an example of some result data and a definition of the same:
-
-@example
-211 56 1000 1059 ifi.discussion
-@end example
-
-The first number is the status, which should be 211.  Next is the
-total number of articles in the group, the lowest article number, the
-highest article number, and finally the group name.  Note that the total
-number of articles may be less than one might think while just
-considering the highest and lowest article numbers, but some articles
-may have been canceled.  Gnus just discards the total-number, so
-whether one should take the bother to generate it properly (if that is a
-problem) is left as an exercise to the reader.
-
-@example
-group-status = [ error / info ] eol
-error        = [ "4" / "5" ] 2<number> " " <Error message>
-info         = "211 " 3* [ <number> " " ] <string>
-@end example
-
-
-@item (nnchoke-close-group GROUP &optional SERVER)
-
-Close @var{group} and free any resources connected to it.  This will be
-a no-op on most backends.
-
-There should be no data returned.
-
-
-@item (nnchoke-request-list &optional SERVER)
-
-Return a list of all groups available on @var{server}.  And that means
-@emph{all}.
-
-Here's an example from a server that only carries two groups:
-
-@example
-ifi.test 0000002200 0000002000 y
-ifi.discussion 3324 3300 n
-@end example
-
-On each line we have a group name, then the highest article number in
-that group, the lowest article number, and finally a flag.
-
-@example
-active-file = *active-line
-active-line = name " " <number> " " <number> " " flags eol
-name        = <string>
-flags       = "n" / "y" / "m" / "x" / "j" / "=" name
-@end example
-
-The flag says whether the group is read-only (@samp{n}), is moderated
-(@samp{m}), is dead (@samp{x}), is aliased to some other group
-(@samp{=other-group}) or none of the above (@samp{y}).
-
-
-@item (nnchoke-request-post &optional SERVER)
-
-This function should post the current buffer.  It might return whether
-the posting was successful or not, but that's not required.  If, for
-instance, the posting is done asynchronously, it has generally not been
-completed by the time this function concludes.  In that case, this
-function should set up some kind of sentinel to beep the user loud and
-clear if the posting could not be completed.
-
-There should be no result data from this function.

-

-
-@item (nnchoke-retrieve-groups GROUPS &optional SERVER)
-
-@var{groups} is a list of groups, and this function should request data
-on all those groups.  How it does it is of no concern to Gnus, but it
-should attempt to do this in a speedy fashion.
-
-The return value of this function can be either @code{active} or
-@code{group}, which says what the format of the result data is.  The
-former is in the same format as the data from
-@code{nnchoke-request-list}, while the latter is a buffer full of lines
-in the same format as @code{nnchoke-request-group} gives.
-
-@example
-group-buffer = *active-line / *group-status
-@end example
-
-
-@item (nnchoke-request-update-info GROUP INFO &optional SERVER)
-
-A Gnus group info (@pxref{Group Info}) is handed to the backend for
-alterations.  This comes in handy if the backend really carries all the
-information (as is the case with virtual and imap groups).  This
-function should destructively alter the info to suit its needs, and
-should return the (altered) group info.
-
-There should be no result data from this function.
-
-
-@item (nnchoke-request-type GROUP &optional ARTICLE)
-
-When the user issues commands for ``sending news'' (@kbd{F} in the
-summary buffer, for instance), Gnus has to know whether the article the
-user is following up on is news or mail.  This function should return
-@code{news} if @var{article} in @var{group} is news, @code{mail} if it
-is mail and @code{unknown} if the type can't be decided.  (The
-@var{article} parameter is necessary in @code{nnvirtual} groups which
-might very well combine mail groups and news groups.)  Both @var{group}
-and @var{article} may be @code{nil}.
-
-There should be no result data from this function.
-

-@item (nnchoke-request-set-mark GROUP ACTION &optional SERVER)
-
-Set/remove/add marks on articles. Normally Gnus handles the article
-marks (such as read, ticked, expired etc) internally, and store them in
-@code{~/.newsrc.eld}. Some backends (such as IMAP) however carry all
-information about the articles on the server, so Gnus need to propagate
-the mark information to the server.
-
-ACTION is a list of mark setting requests, having this format:
-
-@example
-(RANGE ACTION MARK)
-@end example
-
-Range is a range of articles you wish to update marks on. Action is
-@code{set}, @code{add} or @code{del}, respectively used for removing all
-existing marks and setting them as specified, adding (preserving the
-marks not mentioned) mark and removing (preserving the marks not
-mentioned) marks. Mark is a list of marks; where each mark is a
-symbol. Currently used marks are @code{read}, @code{tick}, @code{reply},
-@code{expire}, @code{killed}, @code{dormant}, @code{save},
-@code{download} and @code{unsend}, but your backend should, if possible,
-not limit itself to theese.
-
-Given contradictory actions, the last action in the list should be the
-effective one. That is, if your action contains a request to add the
-@code{tick} mark on article 1 and, later in the list, a request to
-remove the mark on the same article, the mark should in fact be removed.
-
-An example action list:
-
-@example
-(((5 12 30) 'del '(tick))
- ((10 . 90) 'add '(read expire))
- ((92 94) 'del '(read)))
-@end example
-
-The function should return a range of articles it wasn't able to set the
-mark on (currently not used for anything).
-
-There should be no result data from this function.
-
-@item (nnchoke-request-update-mark GROUP ARTICLE MARK)
-
-If the user tries to set a mark that the backend doesn't like, this
-function may change the mark.  Gnus will use whatever this function
-returns as the mark for @var{article} instead of the original
-@var{mark}.  If the backend doesn't care, it must return the original
-@var{mark}, and not @code{nil} or any other type of garbage.
-
-The only use for this I can see is what @code{nnvirtual} does with
-it---if a component group is auto-expirable, marking an article as read
-in the virtual group should result in the article being marked as
-expirable.
-
-There should be no result data from this function.
-
-
-@item (nnchoke-request-scan &optional GROUP SERVER)
-
-This function may be called at any time (by Gnus or anything else) to
-request that the backend check for incoming articles, in one way or
-another.  A mail backend will typically read the spool file or query the
-POP server when this function is invoked.  The @var{group} doesn't have
-to be heeded---if the backend decides that it is too much work just
-scanning for a single group, it may do a total scan of all groups.  It
-would be nice, however, to keep things local if that's practical.
-
-There should be no result data from this function.
-
-
-@item (nnchoke-request-group-description GROUP &optional SERVER)
-
-The result data from this function should be a description of
-@var{group}.
-
-@example
-description-line = name <TAB> description eol
-name             = <string>
-description      = <text>
-@end example
-
-@item (nnchoke-request-list-newsgroups &optional SERVER)
-
-The result data from this function should be the description of all
-groups available on the server.
-
-@example
-description-buffer = *description-line
-@end example
-
-
-@item (nnchoke-request-newgroups DATE &optional SERVER)
-
-The result data from this function should be all groups that were
-created after @samp{date}, which is in normal human-readable date
-format.  The data should be in the active buffer format.
-
-
-@item (nnchoke-request-create-group GROUP &optional SERVER)
-
-This function should create an empty group with name @var{group}.
-
-There should be no return data.
-
-
-@item (nnchoke-request-expire-articles ARTICLES &optional GROUP SERVER FORCE)
-
-This function should run the expiry process on all articles in the
-@var{articles} range (which is currently a simple list of article
-numbers.)  It is left up to the backend to decide how old articles
-should be before they are removed by this function.  If @var{force} is
-non-@code{nil}, all @var{articles} should be deleted, no matter how new
-they are.
-
-This function should return a list of articles that it did not/was not
-able to delete.
-
-There should be no result data returned.
-
-
-@item (nnchoke-request-move-article ARTICLE GROUP SERVER ACCEPT-FORM
-&optional LAST)
-
-This function should move @var{article} (which is a number) from
-@var{group} by calling @var{accept-form}.
-
-This function should ready the article in question for moving by
-removing any header lines it has added to the article, and generally
-should ``tidy up'' the article.  Then it should @code{eval}
-@var{accept-form} in the buffer where the ``tidy'' article is.  This
-will do the actual copying.  If this @code{eval} returns a
-non-@code{nil} value, the article should be removed.
-
-If @var{last} is @code{nil}, that means that there is a high likelihood
-that there will be more requests issued shortly, so that allows some
-optimizations.
-
-The function should return a cons where the @code{car} is the group name and
-the @code{cdr} is the article number that the article was entered as.
-
-There should be no data returned.
-
-
-@item (nnchoke-request-accept-article GROUP &optional SERVER LAST)
-
-This function takes the current buffer and inserts it into @var{group}.
-If @var{last} in @code{nil}, that means that there will be more calls to
-this function in short order.
-
-The function should return a cons where the @code{car} is the group name and
-the @code{cdr} is the article number that the article was entered as.
-
-There should be no data returned.
-
-
-@item (nnchoke-request-replace-article ARTICLE GROUP BUFFER)
-
-This function should remove @var{article} (which is a number) from
-@var{group} and insert @var{buffer} there instead.
-
-There should be no data returned.
-
-
-@item (nnchoke-request-delete-group GROUP FORCE &optional SERVER)
-
-This function should delete @var{group}.  If @var{force}, it should
-really delete all the articles in the group, and then delete the group
-itself.  (If there is such a thing as ``the group itself''.)
-
-There should be no data returned.
-
-
-@item (nnchoke-request-rename-group GROUP NEW-NAME &optional SERVER)
-
-This function should rename @var{group} into @var{new-name}.  All
-articles in @var{group} should move to @var{new-name}.
-
-There should be no data returned.
-
-@end table

-
-@node Error Messaging
-@subsubsection Error Messaging
-
-@findex nnheader-report
-@findex nnheader-get-report
-The backends should use the function @code{nnheader-report} to report
-error conditions---they should not raise errors when they aren't able to
-perform a request.  The first argument to this function is the backend
-symbol, and the rest are interpreted as arguments to @code{format} if
-there are multiple of them, or just a string if there is one of them.
-This function must always returns @code{nil}.
-
-@lisp
-(nnheader-report 'nnchoke "You did something totally bogus")
-
-(nnheader-report 'nnchoke "Could not request group %s" group)
-@end lisp
-
-Gnus, in turn, will call @code{nnheader-get-report} when it gets a
-@code{nil} back from a server, and this function returns the most
-recently reported message for the backend in question.  This function
-takes one argument---the server symbol.
-
-Internally, these functions access @var{backend}@code{-status-string},
-so the @code{nnchoke} backend will have its error message stored in
-@code{nnchoke-status-string}.
-
-
-@node Writing New Backends
-@subsubsection Writing New Backends
-
-Many backends are quite similar.  @code{nnml} is just like
-@code{nnspool}, but it allows you to edit the articles on the server.
-@code{nnmh} is just like @code{nnml}, but it doesn't use an active file,
-and it doesn't maintain overview databases.  @code{nndir} is just like
-@code{nnml}, but it has no concept of ``groups'', and it doesn't allow
-editing articles.
-
-It would make sense if it were possible to ``inherit'' functions from
-backends when writing new backends.  And, indeed, you can do that if you
-want to.  (You don't have to if you don't want to, of course.)
-
-All the backends declare their public variables and functions by using a
-package called @code{nnoo}.
-
-To inherit functions from other backends (and allow other backends to
-inherit functions from the current backend), you should use the
-following macros:
-
-@table @code
-
-@item nnoo-declare
-This macro declares the first parameter to be a child of the subsequent
-parameters.  For instance:
-
-@lisp
-(nnoo-declare nndir
-  nnml nnmh)
-@end lisp
-
-@code{nndir} has declared here that it intends to inherit functions from
-both @code{nnml} and @code{nnmh}.
-
-@item defvoo
-This macro is equivalent to @code{defvar}, but registers the variable as
-a public server variable.  Most state-oriented variables should be
-declared with @code{defvoo} instead of @code{defvar}.
-
-In addition to the normal @code{defvar} parameters, it takes a list of
-variables in the parent backends to map the variable to when executing
-a function in those backends.
-
-@lisp
-(defvoo nndir-directory nil
-  "Where nndir will look for groups."
-  nnml-current-directory nnmh-current-directory)
-@end lisp
-
-This means that @code{nnml-current-directory} will be set to
-@code{nndir-directory} when an @code{nnml} function is called on behalf
-of @code{nndir}.  (The same with @code{nnmh}.)
-
-@item nnoo-define-basics
-This macro defines some common functions that almost all backends should
-have.
-
-@example
-(nnoo-define-basics nndir)
-@end example
-
-@item deffoo
-This macro is just like @code{defun} and takes the same parameters.  In
-addition to doing the normal @code{defun} things, it registers the
-function as being public so that other backends can inherit it.
-
-@item nnoo-map-functions
-This macro allows mapping of functions from the current backend to
-functions from the parent backends.
-
-@example
-(nnoo-map-functions nndir
-  (nnml-retrieve-headers 0 nndir-current-group 0 0)
-  (nnmh-request-article 0 nndir-current-group 0 0))
-@end example
-
-This means that when @code{nndir-retrieve-headers} is called, the first,
-third, and fourth parameters will be passed on to
-@code{nnml-retrieve-headers}, while the second parameter is set to the
-value of @code{nndir-current-group}.
-
-@item nnoo-import
-This macro allows importing functions from backends.  It should be the
-last thing in the source file, since it will only define functions that
-haven't already been defined.
-
-@example
-(nnoo-import nndir
-  (nnmh
-   nnmh-request-list
-   nnmh-request-newgroups)
-  (nnml))
-@end example
-
-This means that calls to @code{nndir-request-list} should just be passed
-on to @code{nnmh-request-list}, while all public functions from
-@code{nnml} that haven't been defined in @code{nndir} yet should be
-defined now.
-
-@end table

-@node Hooking New Backends Into Gnus
-@subsubsection Hooking New Backends Into Gnus
-
-@vindex gnus-valid-select-methods
-Having Gnus start using your new backend is rather easy---you just
-declare it with the @code{gnus-declare-backend} functions.  This will
-enter the backend into the @code{gnus-valid-select-methods} variable.
-
-@code{gnus-declare-backend} takes two parameters---the backend name and
-an arbitrary number of @dfn{abilities}.
-
-Here's an example:
-
-@lisp
-(gnus-declare-backend "nnchoke" 'mail 'respool 'address)
-@end lisp
-
-The abilities can be:
-
-@table @code
-@item mail
-This is a mailish backend---followups should (probably) go via mail.
-@item post
-This is a newsish backend---followups should (probably) go via news.
-@item post-mail
-This backend supports both mail and news.
-@item none
-This is neither a post nor mail backend---it's something completely
-different.
-@item respool
-It supports respooling---or rather, it is able to modify its source
-articles and groups.
-@item address
-The name of the server should be in the virtual server name.  This is
-true for almost all backends.
-@item prompt-address
-The user should be prompted for an address when doing commands like
-@kbd{B} in the group buffer.  This is true for backends like
-@code{nntp}, but not @code{nnmbox}, for instance.
-@end table
-
-
-@node Mail-like Backends
-@subsubsection Mail-like Backends
-
-One of the things that separate the mail backends from the rest of the
-backends is the heavy dependence by the mail backends on common
-functions in @file{nnmail.el}.  For instance, here's the definition of
-@code{nnml-request-scan}:
-
-@lisp
-(deffoo nnml-request-scan (&optional group server)
-  (setq nnml-article-file-alist nil)
-  (nnmail-get-new-mail 'nnml 'nnml-save-nov nnml-directory group))
-@end lisp
-
-It simply calls @code{nnmail-get-new-mail} with a few parameters,
-and @code{nnmail} takes care of all the moving and splitting of the
-mail.
-
-This function takes four parameters.
-
-@table @var
-@item method
-This should be a symbol to designate which backend is responsible for
-the call.
-
-@item exit-function
-This function should be called after the splitting has been performed.
-
-@item temp-directory
-Where the temporary files should be stored.
-
-@item group
-This optional argument should be a group name if the splitting is to be
-performed for one group only.
-@end table
-
-@code{nnmail-get-new-mail} will call @var{backend}@code{-save-mail} to
-save each article.  @var{backend}@code{-active-number} will be called to
-find the article number assigned to this article.
-
-The function also uses the following variables:
-@var{backend}@code{-get-new-mail} (to see whether to get new mail for
-this backend); and @var{backend}@code{-group-alist} and
-@var{backend}@code{-active-file} to generate the new active file.
-@var{backend}@code{-group-alist} should be a group-active alist, like
-this:
-
-@example
-(("a-group" (1 . 10))
- ("some-group" (34 . 39)))
-@end example
-

-@node Score File Syntax
-@subsection Score File Syntax
-
-Score files are meant to be easily parseable, but yet extremely
-mallable.   It was decided that something that had the same read syntax
-as an Emacs Lisp list would fit that spec.
-
-Here's a typical score file:
-
-@lisp
-(("summary"
-  ("win95" -10000 nil s)
-  ("Gnus"))
- ("from"
-  ("Lars" -1000))
- (mark -100))
-@end lisp
-
-BNF definition of a score file:

-@end example
-
-Any unrecognized elements in a score file should be ignored, but not
-discarded.
-
-As you can see, white space is needed, but the type and amount of white
-space is irrelevant.  This means that formatting of the score file is
-left up to the programmer---if it's simpler to just spew it all out on
-one looong line, then that's ok.
-
-The meaning of the various atoms are explained elsewhere in this
-manual (@pxref{Score File Format}).

-
-@node Headers
-@subsection Headers
-
-Internally Gnus uses a format for storing article headers that
-corresponds to the @sc{nov} format in a mysterious fashion.  One could
-almost suspect that the author looked at the @sc{nov} specification and
-just shamelessly @emph{stole} the entire thing, and one would be right.
-
-@dfn{Header} is a severely overloaded term.  ``Header'' is used in
-RFC1036 to talk about lines in the head of an article (e.g.,
-@code{From}).  It is used by many people as a synonym for
-``head''---``the header and the body''.  (That should be avoided, in my
-opinion.)  And Gnus uses a format internally that it calls ``header'',
-which is what I'm talking about here.  This is a 9-element vector,
-basically, with each header (ouch) having one slot.
-
-These slots are, in order: @code{number}, @code{subject}, @code{from},
-@code{date}, @code{id}, @code{references}, @code{chars}, @code{lines},
-@code{xref}, and @code{extra}.  There are macros for accessing and
-setting these slots---they all have predictable names beginning with
-@code{mail-header-} and @code{mail-header-set-}, respectively.
-
-All these slots contain strings, except the @code{extra} slot, which
-contains an alist of header/value pairs (@pxref{To From Newsgroups}).
-
-
-@node Ranges
-@subsection Ranges
-
-@sc{gnus} introduced a concept that I found so useful that I've started
-using it a lot and have elaborated on it greatly.
-
-The question is simple: If you have a large amount of objects that are
-identified by numbers (say, articles, to take a @emph{wild} example)
-that you want to qualify as being ``included'', a normal sequence isn't
-very useful.  (A 200,000 length sequence is a bit long-winded.)
-
-The solution is as simple as the question: You just collapse the
-sequence.
-
-@example
-(1 2 3 4 5 6 10 11 12)
-@end example
-
-is transformed into
-
-@example
-((1 . 6) (10 . 12))
-@end example
-
-To avoid having those nasty @samp{(13 . 13)} elements to denote a
-lonesome object, a @samp{13} is a valid element:
-
-@example
-((1 . 6) 7 (10 . 12))
-@end example
-
-This means that comparing two ranges to find out whether they are equal
-is slightly tricky:
-
-@example
-((1 . 5) 7 8 (10 . 12))
-@end example
-
-and
-
-@example
-((1 . 5) (7 . 8) (10 . 12))
-@end example
-
-are equal.  In fact, any non-descending list is a range:
-
-@example
-(1 2 3 4 5)
-@end example
-
-is a perfectly valid range, although a pretty long-winded one.  This is
-also valid:
-
-@example
-(1 . 5)
-@end example
-
-and is equal to the previous range.
-
-Here's a BNF definition of ranges.  Of course, one must remember the
-semantic requirement that the numbers are non-descending.  (Any number
-of repetition of the same number is allowed, but apt to disappear in
-range handling.)
-
-@example
-range           = simple-range / normal-range
-simple-range    = "(" number " . " number ")"
-normal-range    = "(" start-contents ")"
-contents        = "" / simple-range *[ " " contents ] /
-                  number *[ " " contents ]
-@end example
-
-Gnus currently uses ranges to keep track of read articles and article
-marks.  I plan on implementing a number of range operators in C if The
-Powers That Be are willing to let me.  (I haven't asked yet, because I
-need to do some more thinking on what operators I need to make life
-totally range-based without ever having to convert back to normal
-sequences.)
-
-
-@node Group Info
-@subsection Group Info
-
-Gnus stores all permanent info on groups in a @dfn{group info} list.
-This list is from three to six elements (or more) long and exhaustively
-describes the group.
-
-Here are two example group infos; one is a very simple group while the
-second is a more complex one:
-
-@example
-("no.group" 5 ((1 . 54324)))
-
-("nnml:my.mail" 3 ((1 . 5) 9 (20 . 55))
-                ((tick (15 . 19)) (replied 3 6 (19 . 3)))
-                (nnml "")
-                ((auto-expire . t) (to-address . "ding@@gnus.org")))
-@end example
-
-The first element is the @dfn{group name}---as Gnus knows the group,
-anyway.  The second element is the @dfn{subscription level}, which
-normally is a small integer.  (It can also be the @dfn{rank}, which is a
-cons cell where the @code{car} is the level and the @code{cdr} is the
-score.)  The third element is a list of ranges of read articles.  The
-fourth element is a list of lists of article marks of various kinds.
-The fifth element is the select method (or virtual server, if you like).
-The sixth element is a list of @dfn{group parameters}, which is what
-this section is about.
-
-Any of the last three elements may be missing if they are not required.
-In fact, the vast majority of groups will normally only have the first
-three elements, which saves quite a lot of cons cells.
-
-Here's a BNF definition of the group info format:
-
-@example
-info          = "(" group space ralevel space read
-                [ "" / [ space marks-list [ "" / [ space method [ "" /
-                space parameters ] ] ] ] ] ")"
-group         = quote <string> quote
-ralevel       = rank / level
-level         = <integer in the range of 1 to inf>
-rank          = "(" level "." score ")"
-score         = <integer in the range of 1 to inf>
-read          = range
-marks-lists   = nil / "(" *marks ")"
-marks         = "(" <string> range ")"
-method        = "(" <string> *elisp-forms ")"
-parameters    = "(" *elisp-forms ")"
-@end example
-
-Actually that @samp{marks} rule is a fib.  A @samp{marks} is a
-@samp{<string>} consed on to a @samp{range}, but that's a bitch to say
-in pseudo-BNF.
-
-If you have a Gnus info and want to access the elements, Gnus offers a
-series of macros for getting/setting these elements.
-
-@table @code
-@item gnus-info-group
-@itemx gnus-info-set-group
-@findex gnus-info-group
-@findex gnus-info-set-group
-Get/set the group name.
-
-@item gnus-info-rank
-@itemx gnus-info-set-rank
-@findex gnus-info-rank
-@findex gnus-info-set-rank
-Get/set the group rank (@pxref{Group Score}).
-
-@item gnus-info-level
-@itemx gnus-info-set-level
-@findex gnus-info-level
-@findex gnus-info-set-level
-Get/set the group level.
-
-@item gnus-info-score
-@itemx gnus-info-set-score
-@findex gnus-info-score
-@findex gnus-info-set-score
-Get/set the group score (@pxref{Group Score}).
-
-@item gnus-info-read
-@itemx gnus-info-set-read
-@findex gnus-info-read
-@findex gnus-info-set-read
-Get/set the ranges of read articles.
-
-@item gnus-info-marks
-@itemx gnus-info-set-marks
-@findex gnus-info-marks
-@findex gnus-info-set-marks
-Get/set the lists of ranges of marked articles.
-
-@item gnus-info-method
-@itemx gnus-info-set-method
-@findex gnus-info-method
-@findex gnus-info-set-method
-Get/set the group select method.
-
-@item gnus-info-params
-@itemx gnus-info-set-params
-@findex gnus-info-params
-@findex gnus-info-set-params
-Get/set the group parameters.
-@end table
-
-All the getter functions take one parameter---the info list.  The setter
-functions take two parameters---the info list and the new value.
-
-The last three elements in the group info aren't mandatory, so it may be
-necessary to extend the group info before setting the element.  If this
-is necessary, you can just pass on a non-@code{nil} third parameter to
-the three final setter functions to have this happen automatically.

-@node Extended Interactive
-@subsection Extended Interactive
-@cindex interactive
-@findex gnus-interactive
-
-Gnus extends the standard Emacs @code{interactive} specification
-slightly to allow easy use of the symbolic prefix (@pxref{Symbolic
-Prefixes}).  Here's an example of how this is used:
-
-@lisp
-(defun gnus-summary-increase-score (&optional score symp)
-  (interactive (gnus-interactive "P\ny"))
-  ...
-  )
-@end lisp
-
-The best thing to do would have been to implement
-@code{gnus-interactive} as a macro which would have returned an
-@code{interactive} form, but this isn't possible since Emacs checks
-whether a function is interactive or not by simply doing an @code{assq}
-on the lambda form.  So, instead we have @code{gnus-interactive}
-function that takes a string and returns values that are usable to
-@code{interactive}.
-
-This function accepts (almost) all normal @code{interactive} specs, but
-adds a few more.
-
-@table @samp
-@item y
-@vindex gnus-current-prefix-symbol
-The current symbolic prefix---the @code{gnus-current-prefix-symbol}
-variable.

-
-While Gnus runs under Emacs, XEmacs and Mule, I decided that one of the
-platforms must be the primary one.  I chose Emacs.  Not because I don't
-like XEmacs or Mule, but because it comes first alphabetically.
-
-This means that Gnus will byte-compile under Emacs with nary a warning,
-while XEmacs will pump out gigabytes of warnings while byte-compiling.
-As I use byte-compilation warnings to help me root out trivial errors in
-Gnus, that's very useful.
-
-I've also consistently used Emacs function interfaces, but have used
-Gnusey aliases for the functions.  To take an example:  Emacs defines a
-@code{run-at-time} function while XEmacs defines a @code{start-itimer}
-function.  I then define a function called @code{gnus-run-at-time} that
-takes the same parameters as the Emacs @code{run-at-time}.  When running
-Gnus under Emacs, the former function is just an alias for the latter.
-However, when running under XEmacs, the former is an alias for the
-following function:
-
-@lisp
-(defun gnus-xmas-run-at-time (time repeat function &rest args)
-  (start-itimer
-   "gnus-run-at-time"
-   `(lambda ()
-      (,function ,@@args))
-   time repeat))
-@end lisp
-
-This sort of thing has been done for bunches of functions.  Gnus does
-not redefine any native Emacs functions while running under XEmacs---it
-does this @code{defalias} thing with Gnus equivalents instead.  Cleaner
-all over.
-
-In the cases where the XEmacs function interface was obviously cleaner,
-I used it instead.  For example @code{gnus-region-active-p} is an alias
-for @code{region-active-p} in XEmacs, whereas in Emacs it is a function.
-
-Of course, I could have chosen XEmacs as my native platform and done
-mapping functions the other way around.  But I didn't.  The performance
-hit these indirections impose on Gnus under XEmacs should be slight.

-Q: What is an experienced Emacs user?
-
-@item
-A: A person who wishes that the terminal had pedals.
-@end itemize
-
-Yes, when you use Emacs, you are apt to use the control key, the shift
-key and the meta key a lot.  This is very annoying to some people
-(notably @code{vi}le users), and the rest of us just love the hell out
-of it.  Just give up and submit.  Emacs really does stand for
-``Escape-Meta-Alt-Control-Shift'', and not ``Editing Macros'', as you
-may have heard from other disreputable sources (like the Emacs author).
-
-The shift keys are normally located near your pinky fingers, and are
-normally used to get capital letters and stuff.  You probably use it all
-the time.  The control key is normally marked ``CTRL'' or something like
-that.  The meta key is, funnily enough, never marked as such on any
-keyboard.  The one I'm currently at has a key that's marked ``Alt'',
-which is the meta key on this keyboard.  It's usually located somewhere
-to the left hand side of the keyboard, usually on the bottom row.
-
-Now, us Emacs people don't say ``press the meta-control-m key'',
-because that's just too inconvenient.  We say ``press the @kbd{M-C-m}
-key''.  @kbd{M-} is the prefix that means ``meta'' and ``C-'' is the
-prefix that means ``control''.  So ``press @kbd{C-k}'' means ``press
-down the control key, and hold it down while you press @kbd{k}''.
-``Press @kbd{M-C-k}'' means ``press down and hold down the meta key and
-the control key and then press @kbd{k}''.  Simple, ay?
-
-This is somewhat complicated by the fact that not all keyboards have a
-meta key.  In that case you can use the ``escape'' key.  Then @kbd{M-k}
-means ``press escape, release escape, press @kbd{k}''.  That's much more
-work than if you have a meta key, so if that's the case, I respectfully
-suggest you get a real keyboard with a meta key.  You can't live without
-it.

-
-@node Emacs Lisp
-@subsection Emacs Lisp
-
-Emacs is the King of Editors because it's really a Lisp interpreter.
-Each and every key you tap runs some Emacs Lisp code snippet, and since
-Emacs Lisp is an interpreted language, that means that you can configure
-any key to run any arbitrary code.  You just, like, do it.
-
-Gnus is written in Emacs Lisp, and is run as a bunch of interpreted
-functions.  (These are byte-compiled for speed, but it's still
-interpreted.)  If you decide that you don't like the way Gnus does
-certain things, it's trivial to have it do something a different way.
-(Well, at least if you know how to write Lisp code.)  However, that's
-beyond the scope of this manual, so we are simply going to talk about
-some common constructs that you normally use in your @file{.emacs} file
-to customize Gnus.
-
-If you want to set the variable @code{gnus-florgbnize} to four (4), you
-write the following:
-
-@lisp
-(setq gnus-florgbnize 4)
-@end lisp
-
-This function (really ``special form'') @code{setq} is the one that can
-set a variable to some value.  This is really all you need to know.  Now
-you can go and fill your @code{.emacs} file with lots of these to change
-how Gnus works.
-
-If you have put that thing in your @code{.emacs} file, it will be read
-and @code{eval}ed (which is lisp-ese for ``run'') the next time you
-start Emacs.  If you want to change the variable right away, simply say
-@kbd{C-x C-e} after the closing parenthesis.  That will @code{eval} the
-previous ``form'', which is a simple @code{setq} statement here.
-
-Go ahead---just try it, if you're located at your Emacs.  After you
-@kbd{C-x C-e}, you will see @samp{4} appear in the echo area, which
-is the return value of the form you @code{eval}ed.
-
-Some pitfalls:
-
-If the manual says ``set @code{gnus-read-active-file} to @code{some}'',
-that means:
-
-@lisp
-(setq gnus-read-active-file 'some)
-@end lisp
-
-On the other hand, if the manual says ``set @code{gnus-nntp-server} to
-@samp{nntp.ifi.uio.no}'', that means:
-
-@lisp
-(setq gnus-nntp-server "nntp.ifi.uio.no")
-@end lisp
-
-So be careful not to mix up strings (the latter) with symbols (the
-former).  The manual is unambiguous, but it can be confusing.

-@section Introduction
-
-Most graphical user interface toolkits, such as Motif and XView, provide
-a number of standard user interface controls (sometimes known as
-`widgets' or `gadgets').  Emacs doesn't really support anything like
-this, except for an incredible powerful text ``widget''.  On the other
-hand, Emacs does provide the necessary primitives to implement many
-other widgets within a text buffer.  The @code{widget} package
-simplifies this task.
-
-The basic widgets are:
-
-@table @code
-@item link
-Areas of text with an associated action.  Intended for hypertext links
-embedded in text.
-@item push-button 
-Like link, but intended for stand-alone buttons.
-@item editable-field
-An editable text field.  It can be either variable or fixed length.
-@item menu-choice
-Allows the user to choose one of multiple options from a menu, each
-option is itself a widget.  Only the selected option will be visible in
-the buffer.
-@item radio-button-choice
-Allows the user to choose one of multiple options by pushing radio
-buttons.  The options are implemented as widgets.  All options will be
-visible in the buffer.
-@item item
-A simple constant widget intended to be used in the @code{menu-choice} and
-@code{radio-button-choice} widgets. 
-@item choice-item
-An button item only intended for use in choices.  When pushed, the user
-will be asked to select another option from the choice widget.
-@item toggle
-A simple @samp{on}/@samp{off} switch.
-@item checkbox
-A checkbox (@samp{[ ]}/@samp{[X]}). 
-@item editable-list
-Create an editable list.  The user can insert or delete items in the
-list.  Each list item is itself a widget.
-@end table
-
-Now of what possible use can support for widgets be in a text editor?
-I'm glad you asked.  The answer is that widgets are useful for
-implementing forms.  A @dfn{form} in emacs is a buffer where the user is
-supposed to fill out a number of fields, each of which has a specific
-meaning.  The user is not supposed to change or delete any of the text
-between the fields.  Examples of forms in Emacs are the @file{forms}
-package (of course), the customize buffers, the mail and news compose
-modes, and the @sc{html} form support in the @file{w3} browser.  
-
-The advantages for a programmer of using the @code{widget} package to
-implement forms are:
-
-@enumerate
-@item
-More complex field than just editable text are supported. 
-@item
-You can give the user immediate feedback if he enters invalid data in a
-text field, and sometimes prevent entering invalid data.
-@item 
-You can have fixed sized fields, thus allowing multiple field to be
-lined up in columns.
-@item
-It is simple to query or set the value of a field. 
-@item 
-Editing happens in buffer, not in the mini-buffer.
-@item 
-Packages using the library get a uniform look, making them easier for
-the user to learn.
-@item 
-As support for embedded graphics improve, the widget library will
-extended to support it.  This means that your code using the widget
-library will also use the new graphic features by automatic.
-@end enumerate
-
-In order to minimize the code that is loaded by users who does not
-create any widgets, the code has been split in two files:
-
-@table @file
-@item widget.el
-This will declare the user variables, define the function
-@code{widget-define}, and autoload the function @code{widget-create}. 
-@item wid-edit.el
-Everything else is here, there is no reason to load it explicitly, as
-it will be autoloaded when needed.

-@section User Interface
-
-A form consist of read only text for documentation and some fields,
-where each the fields contain two parts, as tag and a value.  The tags
-are used to identify the fields, so the documentation can refer to the
-foo field, meaning the field tagged with @samp{Foo}. Here is an example
-form:
-
-@example
-Here is some documentation.
-
-Name: @i{My Name}     @strong{Choose}: This option
-Address:  @i{Some Place
-In some City
-Some country.}
-
-See also @b{_other work_} for more information.
-
-Numbers: count to three below
-@b{[INS]} @b{[DEL]} @i{One}
-@b{[INS]} @b{[DEL]} @i{Eh, two?}
-@b{[INS]} @b{[DEL]} @i{Five!}
-@b{[INS]} 
-
-Select multiple:
-
-@b{[X]} This
-@b{[ ]} That
-@b{[X]} Thus
-
-Select one:
-
-@b{(*)} One
-@b{( )} Another One.
-@b{( )} A Final One.
-
-@b{[Apply Form]} @b{[Reset Form]}
-@end example
-
-The top level widgets in is example are tagged @samp{Name},
-@samp{Choose}, @samp{Address}, @samp{_other work_}, @samp{Numbers},
-@samp{Select multiple}, @samp{Select one}, @samp{[Apply Form]}, and
-@samp{[Reset Form]}.  There are basically two thing the user can do within
-a form, namely editing the editable text fields and activating the
-buttons.
-
-@subsection Editable Text Fields
-
-In the example, the value for the @samp{Name} is most likely displayed
-in an editable text field, and so are values for each of the members of
-the @samp{Numbers} list.  All the normal Emacs editing operations are
-available for editing these fields.  The only restriction is that each
-change you make must be contained within a single editable text field.
-For example, capitalizing all text from the middle of one field to the
-middle of another field is prohibited.
-
-Editing text fields are created by the @code{editable-field} widget.
-
-The editing text fields are highlighted with the
-@code{widget-field-face} face, making them easy to find.
-
-@deffn Face widget-field-face
-Face used for other editing fields.
-@end deffn
-
-@subsection Buttons
-
-Some portions of the buffer have an associated @dfn{action}, which can
-be @dfn{activated} by a standard key or mouse command.  These portions
-are called @dfn{buttons}.  The default commands for activating a button
-are:
-
-@table @kbd
-@item @key{RET}
-@deffn Command widget-button-press @var{pos} &optional @var{event}
-Activate the button at @var{pos}, defaulting to point.
-If point is not located on a button, activate the binding in
-@code{widget-global-map} (by default the global map).
-@end deffn
-
-@item mouse-2
-@deffn Command widget-button-click @var{event}
-Activate the button at the location of the mouse pointer.  If the mouse
-pointer is located in an editable text field, activate the binding in
-@code{widget-global-map} (by default the global map).
-@end deffn
-@end table
-
-There are several different kind of buttons, all of which are present in
-the example:
-
-@table @emph
-@item The Option Field Tags.
-When you activate one of these buttons, you will be asked to choose
-between a number of different options.  This is how you edit an option
-field.  Option fields are created by the @code{menu-choice} widget.  In
-the example, @samp{@b{Choose}} is an option field tag.
-@item The @samp{@b{[INS]}} and @samp{@b{[DEL]}} buttons.
-Activating these will insert or delete elements from a editable list.
-The list is created by the @code{editable-list} widget. 
-@item Embedded Buttons.
-The @samp{@b{_other work_}} is an example of an embedded
-button. Embedded buttons are not associated with a fields, but can serve
-any purpose, such as implementing hypertext references.  They are
-usually created by the @code{link} widget.
-@item The @samp{@b{[ ]}} and @samp{@b{[X]}} buttons.
-Activating one of these will convert it to the other.  This is useful
-for implementing multiple-choice fields.  You can create it wit
-@item The @samp{@b{( )}} and @samp{@b{(*)}} buttons.
-Only one radio button in a @code{radio-button-choice} widget can be selected at any
-time.  When you push one of the unselected radio buttons, it will be
-selected and the previous selected radio button will become unselected. 
-@item The @samp{@b{[Apply Form]}} @samp{@b{[Reset Form]}} buttons.
-These are explicit buttons made with the @code{push-button} widget.  The main
-difference from the @code{link} widget is that the buttons are will be
-displayed as GUI buttons when possible.
-enough. 
-@end table
-
-To make them easier to locate, buttons are emphasized in the buffer.  
-
-@deffn Face widget-button-face
-Face used for buttons.
-@end deffn
-
-@defopt widget-mouse-face

-Widgets are created with @code{widget-create}, which returns a
-@dfn{widget} object.  This object can be queried and manipulated by
-other widget functions, until it is deleted with @code{widget-delete}.
-After the widgets have been created, @code{widget-setup} must be called
-to enable them.
-
-@defun widget-create type [ keyword argument ]@dots{}
-Create and return a widget of type @var{type}.
-The syntax for the @var{type} argument is described in @ref{Basic Types}.
-
-The keyword arguments can be used to overwrite the keyword arguments
-that are part of @var{type}.
-@end defun
-
-@defun widget-delete widget
-Delete @var{widget} and remove it from the buffer.
-@end defun
-
-@defun widget-setup 
-Setup a buffer to support widgets. 
-
-This should be called after creating all the widgets and before allowing
-the user to edit them.
-@refill
-@end defun
-
-If you want to insert text outside the widgets in the form, the
-recommended way to do that is with @code{widget-insert}.
-
-@defun widget-insert 
-Insert the arguments, either strings or characters, at point.
-The inserted text will be read only.
-@end defun
-
-There is a standard widget keymap which you might find useful.

-
-The syntax of a type specification is given below:
-
-@example
-NAME ::= (NAME [KEYWORD ARGUMENT]... ARGS)
-     |   NAME
-@end example
-
-Where, @var{name} is a widget name, @var{keyword} is the name of a
-property, @var{argument} is the value of the property, and @var{args}
-are interpreted in a widget specific way.
-
-There following keyword arguments that apply to all widgets:
-
-@table @code
-@item :value
-The initial value for widgets of this type.
-
-@item :format
-This string will be inserted in the buffer when you create a widget.
-The following @samp{%} escapes are available:
-
-@table @samp
-@item %[
-@itemx %]
-The text inside will be marked as a button.
-
-@item %@{
-@itemx %@}
-The text inside will be displayed with the face specified by
-@code{:sample-face}. 
-
-@item %v
-This will be replaces with the buffer representation of the widgets
-value.  What this is depends on the widget type.
-
-@item %d
-Insert the string specified by @code{:doc} here.
-
-@item %h
-Like @samp{%d}, with the following modifications: If the documentation
-string is more than one line, it will add a button which will toggle
-between showing only the first line, and showing the full text.
-Furthermore, if there is no @code{:doc} property in the widget, it will
-instead examine the @code{:documentation-property} property.  If it is a
-lambda expression, it will be called with the widget's value as an
-argument, and the result will be used as the documentation text.
-
-@item %t
-Insert the string specified by @code{:tag} here, or the @code{princ}
-representation of the value if there is no tag.
-
-@item %%
-Insert a literal @samp{%}. 
-@end table
-
-@item :button-face
-Face used to highlight text inside %[ %] in the format.
-
-@item :doc
-The string inserted by the @samp{%d} escape in the format
-string.  
-
-@item :tag
-The string inserted by the @samp{%t} escape in the format
-string.

-@item :help-echo
-Message displayed whenever you move to the widget with either
-@code{widget-forward} or @code{widget-backward}.
-
-@item :indent
-An integer indicating the absolute number of spaces to indent children
-of this widget.
-
-@item :offset
-An integer indicating how many extra spaces to add to the widget's
-grandchildren compared to this widget.
-
-@item :extra-offset
-An integer indicating how many extra spaces to add to the widget's
-children compared to this widget.
-
-@item :notify
-A function called each time the widget or a nested widget is changed.
-The function is called with two or three arguments.  The first argument
-is the widget itself, the second argument is the widget that was
-changed, and the third argument is the event leading to the change, if
-any. 
-
-@item :menu-tag
-Tag used in the menu when the widget is used as an option in a
-@code{menu-choice} widget.
-
-@item :menu-tag-get
-Function used for finding the tag when the widget is used as an option
-in a @code{menu-choice} widget.  By default, the tag used will be either the
-@code{:menu-tag} or @code{:tag} property if present, or the @code{princ}
-representation of the @code{:value} property if not.
-
-@item :match
-Should be a function called with two arguments, the widget and a value,
-and returning non-nil if the widget can represent the specified value.
-
-@item :validate
-A function which takes a widget as an argument, and return nil if the
-widgets current value is valid for the widget.  Otherwise, it should
-return the widget containing the invalid data, and set that widgets
-@code{:error} property to a string explaining the error.
-
-@item :tab-order
-Specify the order in which widgets are traversed with
-@code{widget-forward} or @code{widget-backward}.  This is only partially
-implemented.
-
-@enumerate a

-
-@item 
-(Unimplemented) When on a widget with tabbing order @var{n}, go to the
-next widget in the buffer with tabbing order @var{n+1} or @code{nil},
-whichever comes first.
-
-@item
-When on a widget with no tabbing order specified, go to the next widget
-in the buffer with a positive tabbing order, or @code{nil}
-@end enumerate
-
-@item :parent
-The parent of a nested widget (e.g. a @code{menu-choice} item or an
-element of a @code{editable-list} widget).
-
-@item :sibling-args

-The @var{value}, if present, is used to initialize the @code{:value}
-property.  The value should be a string, which will be inserted in
-field.  This widget will match all string values.
-
-The following extra properties are recognized.
-
-@table @code
-@item :size
-The width of the editable field.@*
-By default the field will reach to the end of the line.
-
-@item :value-face
-Face used for highlighting the editable field.  Default is
-@code{widget-field-face}. 
-
-@item :secret
-Character used to display the value.  You can set this to e.g. @code{?*}
-if the field contains a password or other secret information.  By
-default, the value is not secret.
-
-@item :valid-regexp
-By default the @code{:validate} function will match the content of the
-field with the value of this attribute.  The default value is @code{""}
-which matches everything.
-
-@item :keymap
-Keymap used in the editable field.  The default value is
-@code{widget-field-keymap}, which allows you to use all the normal
-editing commands, even if the buffers major mode supress some of them.
-Pressing return activates the function specified by @code{:activate}. 
-
-@item :hide-front-space
-@itemx :hide-rear-space
-In order to keep track of the editable field, emacs places an invisible
-space character in front of the field, and for fixed sized fields also
-in the rear end of the field.  For fields that extent to the end of the
-line, the terminating linefeed serves that purpose instead.  
-
-Emacs will try to make the spaces intangible when it is safe to do so.
-Intangible means that the cursor motion commands will skip over the
-character as if it didn't exist.  This is safe to do when the text
-preceding or following the widget cannot possible change during the
-lifetime of the @code{editable-field} widget.  The preferred way to tell
-Emacs this, is to add text to the @code{:format} property around the
-value.  For example @code{:format "Tag: %v "}.  
-
-You can overwrite the internal safety check by setting the
-@code{:hide-front-space} or @code{:hide-rear-space} properties to
-non-nil.  This is not recommended.  For example, @emph{all} text that
-belongs to a widget (i.e. is created from its @code{:format} string) will
-change whenever the widget changes its value.

-@subsection The Generic Widget.
-
-The @code{const} and @code{sexp} widgets can contain any lisp
-expression.  In the case of the @code{const} widget the user is
-prohibited from editing edit it, which is mainly useful as a component
-of one of the composite widgets.
-
-The syntax for the generic widgets is
-
-@example
-TYPE ::= (const [KEYWORD ARGUMENT]...  [ VALUE ])
-@end example
-
-The @var{value}, if present, is used to initialize the @code{:value}
-property and can be any s-expression.
-
-@deffn Widget const
-This will display any valid s-expression in an immutable part of the
-buffer. 
-@end deffn
-
-@deffn Widget sexp
-This will allow you to edit any valid s-expression in an editable buffer
-field. 
-
-The @code{sexp} widget takes the same keyword arguments as the
-@code{editable-field} widget.
-@end deffn
-
-@node atoms, composite, generic, Sexp Types
-@comment  node-name,  next,  previous,  up
-@subsection Atomic Sexp Widgets.
-
-The atoms are s-expressions that does not consist of other
-s-expressions.  A string is an atom, while a list is a composite type.
-You can edit the value of an atom with the following widgets.  
-
-The syntax for all the atoms are
-
-@example
-TYPE ::= (NAME [KEYWORD ARGUMENT]...  [ VALUE ])
-@end example
-
-The @var{value}, if present, is used to initialize the @code{:value}
-property and must be an expression of the same type as the widget.
-I.e. the string widget can only be initialized with a string.
-
-All the atom widgets take the same keyword arguments as the @code{editable-field}
-widget.
-
-@deffn Widget string
-Allows you to edit a string in an editable field.
-@end deffn
-
-@deffn Widget file
-Allows you to edit a file name in an editable field.  You you activate
-the tag button, you can edit the file name in the mini-buffer with
-completion. 
-
-Keywords:
-@table @code
-@item :must-match
-If this is set to non-nil, only existing file names will be allowed in
-the minibuffer.
-@end table
-@end deffn
-
-@deffn Widget directory
-Allows you to edit a directory name in an editable field.
-Similar to the @code{file} widget.
-@end deffn
-
-@deffn Widget symbol
-Allows you to edit a lisp symbol in an editable field.
-@end deffn
-
-@deffn Widget integer
-Allows you to edit an integer in an editable field.
-@end deffn
-
-@deffn Widget number
-Allows you to edit a number in an editable field.
-@end deffn
-
-@deffn Widget boolean
-Allows you to edit a boolean.  In lisp this means a variable which is
-either nil meaning false, or non-nil meaning true.
-@end deffn
-
-
-@node composite,  , atoms, Sexp Types
-@comment  node-name,  next,  previous,  up
-@subsection Composite Sexp Widgets.
-
-The syntax for the composite are
-
-@example
-TYPE ::= (NAME [KEYWORD ARGUMENT]...  COMPONENT...)
-@end example
-
-Where each @var{component} must be a widget type.  Each component widget
-will be displayed in the buffer, and be editable to the user.
-
-@deffn Widget cons
-The value of a @code{cons} widget is a cons-cell where the car is the
-value of the first component and the cdr is the value of the second
-component.  There must be exactly two components. 
-@end deffn
-
-@deffn Widget lisp
-The value of a @code{lisp} widget is a list containing the value of
-each of its component.
-@end deffn
-
-@deffn Widget vector
-The value of a @code{vector} widget is a vector containing the value of
-each of its component.
-@end deffn
-
-The above suffice for specifying fixed size lists and vectors.  To get
-variable length lists and vectors, you can use a @code{choice},
-@code{set} or @code{repeat} widgets together with the @code{:inline}
-keywords.  If any component of a composite widget has the @code{:inline}
-keyword set, its value must be a list which will then be spliced into
-the composite.  For example, to specify a list whose first element must
-be a file name, and whose remaining arguments should either by the
-symbol @code{t} or two files, you can use the following widget
-specification:
-
-@example
-(list file
-      (choice (const t)
-              (list :inline t
-                    :value ("foo" "bar")
-                    string string)))
-@end example
-
-The value of a widget of this type will either have the form 
-@samp{(file t)} or @code{(file string string)}.
-
-This concept of inline is probably hard to understand.  It was certainly
-hard to implement so instead of confuse you more by trying to explain it
-here, I'll just suggest you meditate over it for a while.
-
-@deffn Widget choice
-Allows you to edit a sexp which may have one of fixed set of types.  It
-is currently implemented with the @code{choice-menu} basic widget, and
-has a similar syntax.
-@end deffn
-
-@deffn Widget set
-Allows you to specify a type which must be a list whose elements all
-belong to given set.  The elements of the list is not significant.  This
-is implemented on top of the @code{checklist} basic widget, and has a
-similar syntax. 
-@end deffn
-
-@deffn Widget repeat
-Allows you to specify a variable length list whose members are all of
-the same type.  Implemented on top of the `editable-list' basic widget,
-and has a similar syntax.

-You can examine or set the value of a widget by using the widget object
-that was returned by @code{widget-create}.
-
-@defun widget-value widget
-Return the current value contained in @var{widget}.
-It is an error to call this function on an uninitialized widget.
-@end defun
-
-@defun widget-value-set widget value
-Set the value contained in @var{widget} to @var{value}.
-It is an error to call this function with an invalid @var{value}.
-@end defun
-
-@strong{Important:} You @emph{must} call @code{widget-setup} after
-modifying the value of a widget before the user is allowed to edit the
-widget again.  It is enough to call @code{widget-setup} once if you
-modify multiple widgets.  This is currently only necessary if the widget
-contains an editing field, but may be necessary for other widgets in the
-future. 
-
-If your application needs to associate some information with the widget
-objects, for example a reference to the item being edited, it can be
-done with @code{widget-put} and @code{widget-get}.  The property names
-must begin with a @samp{:}.
-
-@defun widget-put widget property value
-In @var{widget} set @var{property} to @var{value}.
-@var{property} should be a symbol, while @var{value} can be anything.
-@end defun
-
-@defun widget-get widget property
-In @var{widget} return the value for @var{property}.
-@var{property} should be a symbol, the value is what was last set by
-@code{widget-put} for @var{property}.
-@end defun
-
-@defun widget-member widget property
-Non-nil if @var{widget} has a value (even nil) for property @var{property}.
-@end defun
-
-Occasionally it can be useful to know which kind of widget you have,
-i.e. the name of the widget type you gave when the widget was created. 
-
-@defun widget-type widget
-Return the name of @var{widget}, a symbol.
-@end defun
-
-Widgets can be in two states: active, which means they are modifiable by
-the user, or inactive, which means they cannot be modified by the user.
-You can query or set the state with the following code:
-
-@lisp
-;; Examine if @var{widget} is active or not.
-(if (widget-apply @var{widget} :active)
-    (message "Widget is active.")
-  (message "Widget is inactive.")
-
-;; Make @var{widget} inactive.
-(widget-apply @var{widget} :deactivate)
-
-;; Make @var{widget} active.
-(widget-apply @var{widget} :activate)
-@end lisp
-
-A widget is inactive if itself, or any of its ancestors (found by
-following the @code{:parent} link) have been deactivated.  To make sure
-a widget is really active, you must therefore activate both itself, and
-all its ancestors.
-
-@lisp
-(while widget 
-  (widget-apply widget :activate)
-  (setq widget (widget-get widget :parent)))
-@end lisp
-
-You can check if a widget has been made inactive by examining the value
-of @code{:inactive} keyword.  If this is non-nil, the widget itself has
-been deactivated.  This is different from using the @code{:active}
-keyword, in that the later tell you if the widget @strong{or} any of its
-ancestors have been deactivated.   Do not attempt to set the
-@code{:inactive} keyword directly.  Use the @code{:activate}
-@code{:deactivated} keywords instead.

-@section Defining New Widgets
-
-You can define specialized widgets with @code{define-widget}.  It allows
-you to create a shorthand for more complex widgets, including specifying
-component widgets and default new default values for the keyword
-arguments. 
-
-@defun widget-define name class doc &rest args
-Define a new widget type named @var{name} from @code{class}.
-
-@var{name} and class should both be symbols, @code{class} should be one
-of the existing widget types. 
-
-The third argument @var{DOC} is a documentation string for the widget.
-
-After the new widget has been defined, the following two calls will
-create identical widgets:
-
-@itemize @bullet
-@item
-@lisp
-(widget-create @var{name})
-@end lisp
-
-@item
-@lisp
-(apply widget-create @var{class} @var{args})
-@end lisp
-@end itemize
-
-@end defun
-
-Using @code{widget-define} does just store the definition of the widget
-type in the @code{widget-type} property of @var{name}, which is what
-@code{widget-create} uses.
-
-If you just want to specify defaults for keywords with no complex
-conversions, you can use @code{identity} as your conversion function.
-
-The following additional keyword arguments are useful when defining new
-widgets: 
-@table @code
-@item :convert-widget
-Function to convert a widget type before creating a widget of that
-type.  It takes a widget type as an argument, and returns the converted
-widget type.  When a widget is created, this function is called for the
-widget type and all the widgets parent types, most derived first. 
-
-@item :value-to-internal
-Function to convert the value to the internal format.  The function
-takes two arguments, a widget and an external value, and returns the
-internal value.  The function is called on the present @code{:value}
-when the widget is created, and on any value set later with
-@code{widget-value-set}.
-
-@item :value-to-external
-Function to convert the value to the external format.  The function
-takes two arguments, a widget and an internal value, and returns the
-internal value.  The function is called on the present @code{:value}
-when the widget is created, and on any value set later with
-@code{widget-value-set}.
-
-@item :create
-Function to create a widget from scratch.  The function takes one
-argument, a widget type, and create a widget of that type, insert it in
-the buffer, and return a widget object.
-
-@item :delete
-Function to delete a widget.  The function takes one argument, a widget,
-and should remove all traces of the widget from the buffer.
-
-@item :value-create
-Function to expand the @samp{%v} escape in the format string.  It will
-be called with the widget as its argument.  Should
-insert a representation of the widgets value in the buffer.
-
-@item :value-delete
-Should remove the representation of the widgets value from the buffer.
-It will be called with the widget as its argument.  It doesn't have to
-remove the text, but it should release markers and delete nested widgets
-if such has been used.
-
-@item :format-handler
-Function to handle unknown @samp{%} escapes in the format string.  It
-will be called with the widget and the escape character as arguments.
-You can set this to allow your widget to handle non-standard escapes.
-
-You should end up calling @code{widget-default-format-handler} to handle
-unknown escape sequences, which will handle the @samp{%h} and any future
-escape sequences, as well as give an error for unknown escapes.
-@end table
-
-If you want to define a new widget from scratch, use the @code{default}
-widget as its base.
-
-@deffn Widget default [ keyword argument ]
-Widget used as a base for other widgets. 
-
-It provides most of the functionality that is referred to as ``by
-default'' in this text.
