-** Gnus changes.
-
-*** The Gnus distribution no longer bundles Custom and Widget.
-If your Emacs doesn't come with these libraries, fetch them from
-<URL:http://www.dina.kvl.dk/~abraham/custom/>. You also then need to
-add the following to the lisp/dgnushack.el file:
-
- (push "~/lisp/custom" load-path)
-
-Modify to suit your needs.
-
-*** New functionality for using Gnus as an offline newsreader has been
-added. A plethora of new commands and modes have been added. See the
-Gnus manual for the full story.
-
-*** The nndraft backend has returned, but works differently than
-before. All Message buffers are now also articles in the nndraft
-group, which is created automatically.
-
-*** `gnus-alter-header-function' can now be used to alter header
-values.
-
-*** `gnus-summary-goto-article' now accept Message-ID's.
-
-*** A new Message command for deleting text in the body of a message
-outside the region: `C-c C-v'.
-
-*** You can now post to component group in nnvirtual groups with
-`C-u C-c C-c'.
-
-*** `nntp-rlogin-program' -- new variable to ease customization.
-
-*** `C-u C-c C-c' in `gnus-article-edit-mode' will now inhibit
-re-highlighting of the article buffer.
-
-*** New element in `gnus-boring-article-headers' -- `long-to'.
-
-*** `M-i' symbolic prefix command. See the section "Symbolic
-Prefixes" in the Gnus manual for details.
-
-*** `L' and `I' in the summary buffer now take the symbolic prefix
-`a' to add the score rule to the "all.SCORE" file.
-
-*** `gnus-simplify-subject-functions' variable to allow greater
-control over simplification.
-
-*** `A T' -- new command for fetching the current thread.
-
-*** `/ T' -- new command for including the current thread in the
-limit.
-
-*** `M-RET' is a new Message command for breaking cited text.
-
-*** \\1-expressions are now valid in `nnmail-split-methods'.
-
-*** The `custom-face-lookup' function has been removed.
-If you used this function in your initialization files, you must
-rewrite them to use `face-spec-set' instead.
-
-*** Cancelling now uses the current select method. Symbolic prefix
-`a' forces normal posting method.
-
-*** New command to translate M******** sm*rtq**t*s into proper text
--- `W d'.
-
-*** For easier debugging of nntp, you can set `nntp-record-commands'
-to a non-nil value.
-
-*** nntp now uses ~/.authinfo, a .netrc-like file, for controlling
-where and how to send AUTHINFO to NNTP servers.
-
-*** A command for editing group parameters from the summary buffer
-has been added.
-
-*** A history of where mails have been split is available.
-
-*** A new article date command has been added -- `article-date-iso8601'.
-
-*** Subjects can be simplified when threading by setting
-`gnus-score-thread-simplify'.
-
-*** A new function for citing in Message has been added --
-`message-cite-original-without-signature'.
-
-*** `article-strip-all-blank-lines' -- new article command.
-
-*** A new Message command to kill to the end of the article has
-been added.
-
-*** A minimum adaptive score can be specified by using the
-`gnus-adaptive-word-minimum' variable.
-
-*** The "lapsed date" article header can be kept continually
-updated by the `gnus-start-date-timer' command.
-
-*** Web listserv archives can be read with the nnlistserv backend.
-
-*** Old dejanews archives can now be read by nnweb.

-This package contains Semi-gnus.
-
-What is Semi-gnus?
-==================
-
- Semi-gnus is a replacement of Gnus with gnus-mime for SEMI. It has
-all features of Gnus and gnus-mime, so there are no need to install
-Gnus to use it, and you must not use gnus-mime for SEMI.
-
- It requires SEMI package, so please get and install SEMI package
-before to install it.
-
-
-How to get?
-===========
-
-(0) cvs login
-
- % cvs -d :pserver:anonymous@chamonix.jaist.ac.jp:/hare/cvs/root \

-
-(2) compile
-
- ;; as same as Gnus
-
- % cd gnus
-
- % make EMACS=<file name of your emacs>
-
-(3) update
-
- Please do following in your Open gnus directory:
-
- % cvs update -r semi-gnus
-
-
- (semi-)daily snapshot is also available from
-

-Subject: So you want to use the new Gnus
-Message-ID: <lars-doc1@eyesore.no>
-
-Actually, since you are reading this, chances are you are already
-using the new Gnus. Congratulations.
-
-This entire newsgroup you are reading is, in fact, no real newsgroup
-at all, in the traditional sense. It is an example of one of the
-"foreign" select methods that Gnus may use.
-
-The text you are now reading is stored in the "etc" directory with the
-rest of the Emacs sources. You are using the "nndoc" backend for
-accessing it. Scary, isn't it?
-
-This isn't the real documentation. `M-x info', `m gnus <RET>' to read
-that. This "newsgroup" is intended as a kinder, gentler way of getting
-people started.
-
-Gnus is a rewrite of GNUS 4.1, written by Masanobu Umeda. The rewrite
-was done by moi, yours truly, your humble servant, Lars Magne
-Ingebrigtsen. If you have a WWW browser, you can investigate to your
-heart's delight at <URL:http://www.ifi.uio.no/~larsi/larsi.html>.

-Subject: Starting up
-Message-ID: <lars-doc2@eyesore.no>
-
-If you are having problems with Gnus not finding your server, you have
-to set `gnus-select-method'. A "method" is a way of specifying *how*
-the news is to be found, and from *where*.
-
-Say you want to read news from you local, friendly nntp server
-"news.my.local.server".
-
-(setq gnus-select-method '(nntp "news.my.local.server"))
-
-Quite easy, huh?
-
-From the news spool:
-
-(setq gnus-select-method '(nnspool ""))
-
-From your mh-e spool:
-
-(setq gnus-select-method '(nnmh ""))
-
-There's a whole bunch of other methods for reading mail and news, see
-the "Foreign groups" article for that.

-Subject: Where are all the groups, then?
-Message-ID: <lars-doc3@eyesore.no>
-
-If this is the first time you have used a newsreader, you won't have a
-.newsrc file. This means that Gnus will think that all the newsgroups
-on the server are "new", and kill them all.
-
-If you have a .newsrc file, the new groups will be processed with the
-function in the `gnus-subscribe-newsgroup-method' variable, which is
-`gnus-subscribe-zombies' by default.
-
-This means that all the groups have been made into "zombies" - not
-quite dead, but not exactly alive, either.
-
-Jump back to the *Group* buffer, and type `A z' to list all the zombie
-groups. Look though the list, and subscribe to the groups you want to
-read by pressing `u' on the one you think look interesting.
-
-If all the groups have been killed, type `A k' to list all the killed
-groups. Subscribe to them the same way.
-
-When you are satisfied, press `S z' to kill all the zombie groups.
-
-Now you should have a nice list of all groups you are interested in.
-
-(If you later want to subscribe to more groups, press `A k' to
-list all the kill groups, and repeat. You can also type `U' and be
-prompted for groups to subscribe to.)

-Subject: I want to read my mail!
-Message-ID: <lars-doc4@eyesore.no>
-
-Yes, Virginia, you can read mail with Gnus.
-
-First you have to decide which mail backend you want to use. You have
-nnml, which is a one-file-one-mail backend, which is quite nice, but
-apt to make your systems administrator go crazy and come after you
-with a shotgun.
-
-nnmbox uses a Unix mail box to store mail. Nice, but slow.
-
-nnmh uses mh-e folders, which is also a one-file-one-mail thingie, but
-slower than nnml. (It doesn't support NOV files.)
-
-So if you want to go with nnmbox, you can simply say:
-
-(setq gnus-secondary-select-methods '((nnmbox "")))
-
-(The same for the other methods, kind of.)
-
-You should also set `nnmail-split-methods' to something sensible:
-
-(setq nnmail-split-methods
- '(("mail.junk" "From:.*Lars")
- ("mail.misc "")))
-
-This will put all mail from me in you junk mail group, and the rest in
-"mail.misc".
-
-These groups will be subscribe the same way as the normal groups, so
-you will probably find them among the zombie groups after you set
-these variables and re-start Gnus.

-Subject: Foreign newsgroups
-Message-ID: <lars-doc5@eyesore.no>
-
-These are groups that do not come from `gnus-select-method'.
-
-Say you want to read "alt.furniture.couches" from "news.funet.fi". You
-can then either type `B news.funet.fi <RET>' to browse that server and
-subscribe to that group, or you can type
-`G m alt.furniture.couches<RET>nntp<RET>news.funet.fi<RET>', if you
-like to type a lot.
-
-If you want to read a directory as a newsgroup, you can create an
-nndir group, much the same way. There's a shorthand for that,
-though. If, for instance, you want to read the (ding) list archives,
-you could type `G d /ftp <RET>'.
-
-There's lots more to know about foreign groups, but you have to read
-the info pages to find out more.

-Subject: Low level changes in GNUS, or, Wrong type argument: stringp, nil
-Message-ID: <lars-doc6@eyesore.no>
-
-Gnus really isn't GNUS, even though it looks like it. If you scrape
-the surface, you'll find that most things have changed.
-
-This means that old code that relies on GNUS internals will fail.
-
-In particular, `gnus-newsrc-hashtb', `gnus-newsrc-assoc',
-`gnus-killed-list', the `nntp-header-' macros and the display formats
-have all changed. If you have some code lying around that depend on
-these, or change these, you'll have to re-write your code.
-
-Old hilit19 code does not work at all. In fact, you should probably
-remove all hilit code from all the Gnus hooks
-(`gnus-group-prepare-hook', `gnus-summary-prepare-hook' and
-`gnus-summary-article-hook'). (Well, at the very least the first
-two.) Gnus provides various integrated functions for highlighting,
-which are both faster and more accurated.
-
-There is absolutely no chance, whatsoever, of getting Gnus to work
-with Emacs 18. It won't even work on Emacsen older than Emacs
-19.30/XEmacs 19.13. Upgrade your Emacs or die.

-Message-ID: <lars-doc8@eyesore.no>
-
-Reading the active file from the nntp server is a drag.
-
-Just press `M-g' on the mail groups, and they will be re-scanned.
-
-You can also re-scan all the mail groups by putting them on level 1
-(`S l 1'), and saying `1 g' to re-scan all level 1 groups.

-Subject: How do I set up virtual newsgroups?
-Message-ID: <lars-doc9@eyesore.no>
-
-Virtual newsgroups are collections of other newsgroups. Why people
-want this is beyond me, but here goes:
-
-Create the group by saying
-
-`M-a my.virtual.newsgroup<RET>nnvirtual<RET>^rec\.aquaria\.*<RET>'
-
-This will create the group "nnvirtual:my.virtual.newsgroup", which
-will collect all articles from all the groups in the "rec.aquaria"
-hierarchy.
-
-If you want to edit the regular expression, just type `M-e' on the
-group line.
-
-Note that all the groups that are part of the virtual group have to be
-alive. This means that the cannot, absolutely not, be zombie or
-killed. They can be unsubscribed; that's no problem.
-
-You can combine groups from different servers in the same virtual
-newsgroup, something that may actually be useful. Say you have the
-group "comp.headers" on the server "news.server.no" and the same group
-on "news.server.edu". If people have posted articles with Distribution
-headers that stop propagation of their articles, combining these two
-newsgroups into one virtual newsgroup should give you a better view of
-what's going on.
-
-One caveat, though: The virtual group article numbers from the first
-source group (group A) will always be lower than the article numbers
-from the second (group B). This means that Gnus will believe that
-articles from group A are older than articles from group B. Threading
-will lessen these problems, but it might be a good idea to sort the
-threads over the date of the articles to get a correct feel for the
-flow of the groups:
-
-(setq gnus-thread-sort-functions '(gnus-thread-sort-by-date))
-
-If you only want this in virtual groups, you could say something along
-the lines of:
-
-(setq gnus-select-group-hook
- (lambda ()
- (if (eq 'nnvirtual (car (gnus-find-method-for-group
- gnus-newsgroup-name)))
- (progn
- (make-local-variable 'gnus-thread-sort-functions)
- (setq gnus-thread-sort-functions '(gnus-thread-sort-by-date))))))

-Subject: Bugs & stuff
-Message-ID: <lars-doc7@eyesore.no>
-
-If you want to report a bug, please type `M-x gnus-bug'. This will
-give me a precise overview of your Gnus and Emacs version numbers,
-along with a look at all Gnus variables you have changed.
-
-Du not expect a reply back, but your bug should be fixed in the next
-version. If the bug persists, please re-submit your bug report.
-
-When a bug occurs, I need a recipe for how to trigger the bug. You
-have to tell me exactly what you do to uncover the bug, and you should
-(setq debug-on-error t) and send me the backtrace along with the bug
-report.
-
-If I am not able to reproduce the bug, I won't be able to fix it.
-
-I would, of course, prefer that you locate the bug, fix it, and mail
-me the patches, but one can't have everything.
-
-If you have any questions on usage, the "ding@ifi.uio.no" mailing list
-is where to post the questions.

-;; How do I Rate an article??
-;; Before you type n to go to the next article, hit a number from 1-5
-;; Type r in the summary buffer and you will be prompted.
-;; Note that when you're in grouplens-minor-mode 'r' masks the
-;; usual reply binding for 'r'
-;;
-;; What if, Gasp, I find a bug???
-;; Please type M-x gnus-gl-submit-bug-report. This will set up a
-;; mail buffer with the state of variables and buffers that will help
-;; me debug the problem. A short description up front would help too!
-;;
-;; How do I display the prediction for an article:
-;; If you set the gnus-summary-line-format as shown above, the score
-;; (prediction) will be shown automatically.

-;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
-;; Programmer Notes
-;; 10/9/95
-;; gnus-scores-articles contains the articles
-;; When scoring is done, the call tree looks something like:
-;; gnus-possibly-score-headers
-;; ==> gnus-score-headers
-;; ==> gnus-score-load-file
-;; ==> get-all-mids (from the eval form)
-;;
-;; it would be nice to have one that gets called after all the other
-;; headers have been scored.
-;; we may want a variable gnus-grouplens-scale-factor
-;; and gnus-grouplens-offset this would probably be either -3 or 0
-;; to make the scores centered around zero or not.
-;; Notes 10/12/95
-;; According to Lars, Norse god of gnus, the simple way to insert a
-;; call to an external function is to have a function added to the
-;; variable gnus-score-find-files-function This new function
-;; gnus-grouplens-score-alist will return a core alist that
-;; has (("message-id" ("<message-id-xxxx>" score) ("<message-id-xxxy>" score))
-;; This seems like it would be pretty inefficient, though workable.

-(defun gnus-kill-file-mode ()
- "Major mode for editing kill files.
-
-If you are using this mode - you probably shouldn't. Kill files
-perform badly and paint with a pretty broad brush. Score files, on
-the other hand, are vastly faster (40x speedup) and give you more
-control over what to do.
-
-In addition to Emacs-Lisp Mode, the following commands are available:
-
-\\{gnus-kill-file-mode-map}
-
- A kill file contains Lisp expressions to be applied to a selected
-newsgroup. The purpose is to mark articles as read on the basis of
-some set of regexps. A global kill file is applied to every newsgroup,
-and a local kill file is applied to a specified newsgroup. Since a
-global kill file is applied to every newsgroup, for better performance
-use a local one.
-
- A kill file can contain any kind of Emacs Lisp expressions expected
-to be evaluated in the Summary buffer. Writing Lisp programs for this
-purpose is not so easy because the internal working of Gnus must be
-well-known. For this reason, Gnus provides a general function which
-does this easily for non-Lisp programmers.
-
- The `gnus-kill' function executes commands available in Summary Mode
-by their key sequences. `gnus-kill' should be called with FIELD,
-REGEXP and optional COMMAND and ALL. FIELD is a string representing
-the header field or an empty string. If FIELD is an empty string, the
-entire article body is searched for. REGEXP is a string which is
-compared with FIELD value. COMMAND is a string representing a valid
-key sequence in Summary mode or Lisp expression. COMMAND defaults to
-'(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is
-executed in the Summary buffer. If the second optional argument ALL
-is non-nil, the COMMAND is applied to articles which are already
-marked as read or unread. Articles which are marked are skipped over
-by default.
-
- For example, if you want to mark articles of which subjects contain
-the string `AI' as read, a possible kill file may look like:
-
- (gnus-kill \"Subject\" \"AI\")
-
- If you want to mark articles with `D' instead of `X', you can use
-the following expression:
-
- (gnus-kill \"Subject\" \"AI\" \"d\")
-
-In this example it is assumed that the command
-`gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode.
-
- It is possible to delete unnecessary headers which are marked with
-`X' in a kill file as follows:
-
- (gnus-expunge \"X\")
-
- If the Summary buffer is empty after applying kill files, Gnus will
-exit the selected newsgroup normally. If headers which are marked
-with `D' are deleted in a kill file, it is impossible to read articles
-which are marked as read in the previous Gnus sessions. Marks other
-than `D' should be used for articles which should really be deleted.
-
-Entry to this mode calls emacs-lisp-mode-hook and
-gnus-kill-file-mode-hook with no arguments, if that value is non-nil."

-
-When any of the following are true, `gnus-find-new-newsgroups' will instead
-ask the servers (primary, secondary, and archive servers) to list new
-groups since the last time it checked:
- 1. This variable is `ask-server'.
- 2. This variable is a list of select methods (see below).
- 3. `gnus-read-active-file' is nil or `some'.
- 4. A prefix argument is given to `gnus-find-new-newsgroups' interactively.
-
-Thus, if this variable is `ask-server' or a list of select methods or
-`gnus-read-active-file' is nil or `some', then the killed list is no
-longer necessary, so you could safely set `gnus-save-killed-list' to nil.
-
-This variable can be a list of select methods which Gnus will query with
-the `ask-server' method in addition to the primary, secondary, and archive
-servers.

- (setq gnus-check-new-newsgroups

-;;; Commentary:
-
-;; This package allows arbitrary undoing in Gnus buffers. As all the
-;; Gnus buffers aren't very text-oriented (what is in the buffers is
-;; just some random representation of the actual data), normal Emacs
-;; undoing doesn't work at all for Gnus.
-;;
-;; This package works by letting Gnus register functions for reversing
-;; actions, and then calling these functions when the user pushes the
-;; `undo' key. As with normal `undo', there it is possible to set
-;; undo boundaries and so on.
-;;
-;; Internally, the undo sequence is represented by the
-;; `gnus-undo-actions' list, where each element is a list of functions
-;; to be called, in sequence, to undo some action. (An "action" is a
-;; collection of functions.)
-;;
-;; For instance, a function for killing a group will call
-;; `gnus-undo-register' with a function that un-kills the group. This
-;; package will put that function into an action.

-To change the behaviour, you can either edit this variable or set
-`gnus-uu-user-view-rules' to something useful.
-
-For example:
-
-To make gnus-uu use 'xli' to display JPEG and GIF files, put the
-following in your .emacs file:
-
- (setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
-
-Both these variables are lists of lists with two string elements. The
-first string is a regular expression. If the file name matches this
-regular expression, the command in the second string is executed with
-the file as an argument.
-
-If the command string contains \"%s\", the file name will be inserted
-at that point in the command string. If there's no \"%s\" in the
-command string, the file name will be appended to the command string
-before executing.
-
-There are several user variables to tailor the behaviour of gnus-uu to
-your needs. First we have `gnus-uu-user-view-rules', which is the
-variable gnus-uu first consults when trying to decide how to view a
-file. If this variable contains no matches, gnus-uu examines the
-default rule variable provided in this package. If gnus-uu finds no
-match here, it uses `gnus-uu-user-view-rules-end' to try to make a

-;;
-;; The second parameter is the state of the list of articles, and can

-;;
-;; The function should return a list. The list may contain the
-;; following symbols:
-;; `error' if an error occurred
-;; `begin' if the beginning of an encoded file has been received
-;; If the list returned contains a `begin', the first element of
-;; the list *must* be a string with the file name of the decoded

-;; `middle' if the article was a body part of an encoded file
-;; `wrong-type' if the article was not a part of an encoded file

-with some simple extensions.

-%d Date of the article (string) in DD-MMM format
-%M Message-id of the article (string)
-%r References of the article (string)
-%c Number of characters in the article (integer)
-%L Number of lines in the article (integer)
-%I Indentation based on thread level (a string of spaces)
-%T A string with two possible values: 80 spaces if the article
- is on thread level two or larger and 0 spaces on level one
-%R \"A\" if this article has been replied to, \" \" otherwise (character)
-%U Status of this article (character, \"R\", \"K\", \"-\" or \" \")
-%[ Opening bracket (character, \"[\" or \"<\")
-%] Closing bracket (character, \"]\" or \">\")
-%> Spaces of length thread-level (string)
-%< Spaces of length (- 20 thread-level) (string)
-%i Article score (number)
-%z Article zcore (character)
-%t Number of articles under the current thread (number).
-%e Whether the thread is empty or not (character).
-%l GroupLens score (string).
-%V Total thread score (number).
-%P The line number (number).
-%O Download mark (character).
-%u User defined specifier. The next character in the format string should
- be a letter. Gnus will call the function gnus-user-format-function-X,
- where X is the letter following %u. The function will be passed the
- current header as argument. The function should return a string, which
- will be inserted into the summary just like information from any other
- summary specifier.
-
-Text between %( and %) will be highlighted with `gnus-mouse-face'
-when the mouse point is placed inside the area. There can only be one
-such area.
-
-The %U (status), %R (replied) and %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 illegal to have these specs after a variable-length spec. Well,
-you might not be arrested, but your summary buffer will look strange,
-which is bad enough.
-
-The smart choice is to have these specs as for to the left as
-possible.
-
-This restriction may disappear in later versions of Gnus."

-
-;;; 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.
-

-(require 'cl)

-;; 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 was based upon Kai Grossjohan's shamessly snarfed code and
-;;; further modified by Joe Hildebrand. It has been updated for Red
-;;; Gnus.
-
-;; TODO:
-;;
-;; * Fix bug where server connection can be lost and impossible to regain
-;; This hasn't happened to me in a while; think it was fixed in Rgnus
-;;
-;; * make it handle different nndb servers seemlessly
-;;
-;; * Optimize expire if FORCE
-;;
-;; * Optimize move (only expire once)
-;;
-;; * Deal with add/deletion of groups
-;;
-;; * make the backend TOUCH an article when marked as expireable (will
-;; make article expire 'expiry' days after that moment).
-
-;;-
-;; Register nndb with known select methods.

-;; The format of a header is now:

-
-\(FIELD VALUE SPLIT): If the message field FIELD (a regexp) contains
- VALUE (a regexp), store the messages as specified by SPLIT.
-
-\(| SPLIT...): Process each SPLIT expression until one of them matches.
- A SPLIT expression is said to match if it will cause the mail
- message to be stored in one or more groups.
-
-\(& SPLIT...): Process each SPLIT expression.
-
-\(: FUNCTION optional args): Call FUNCTION with the optional args, in
- the buffer containing the message headers. The return value FUNCTION
- should be a split, which is then recursively processed.
-
-FIELD must match a complete field name. VALUE must match a complete
-word according to the `nnmail-split-fancy-syntax-table' syntax table.
-You can use \".*\" in the regexps to match partial field names or words.
-
-FIELD and VALUE can also be lisp symbols, in that case they are expanded
-as specified in `nnmail-split-abbrev-alist'.
-

-;;; We map between virtual articles and real articles in a manner
-;;; which keeps the size of the virtual active list the same as
-;;; the sum of the component active lists.
-;;; To achieve fair mixing of the groups, the last article in
-;;; each of N component groups will be in the the last N articles
-;;; in the virtual group.
-
-;;; If you have 3 components A, B and C, with articles 1-8, 1-5, and 6-7
-;;; resprectively, then the virtual article numbers look like:
-;;;
-;;; 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
-;;; A1 A2 A3 A4 B1 A5 B2 A6 B3 A7 B4 C6 A8 B5 C7
-
-;;; To compute these mappings we generate a couple tables and then
-;;; do some fast operations on them. Tables for the example above:
-;;;
-;;; Offsets - [(A 0) (B -3) (C -1)]
-;;;
-;;; a b c d e
-;;; Mapping - ([ 3 0 1 3 0 ]
-;;; [ 6 3 2 9 3 ]
-;;; [ 8 6 3 15 9 ])
-;;;
-;;; (note column 'e' is different in real algorithm, which is slightly
-;;; different than described here, but this gives you the methodology.)
-;;;
-;;; The basic idea is this, when going from component->virtual, apply
-;;; the appropriate offset to the article number. Then search the first
-;;; column of the table for a row where 'a' is less than or equal to the
-;;; modified number. You can see that only group A can therefore go to
-;;; the first row, groups A and B to the second, and all to the last.
-;;; The third column of the table is telling us the number of groups
-;;; which might be able to reach that row (it might increase by more than
-;;; 1 if several groups have the same size).
-;;; Then column 'b' provides an additional offset you apply when you have
-;;; found the correct row. You then multiply by 'c' and add on the groups
-;;; _position_ in the offset table. The basic idea here is that on
-;;; any given row we are going to map back and forth using X'=X*c+Y and
-;;; X=(X'/c), Y=(X' mod c). Then once you've done this transformation,
-;;; you apply a final offset from column 'e' to give the virtual article.
-;;;
-;;; Going the other direction, you instead search on column 'd' instead
-;;; of 'a', and apply everything in reverse order.
-
-;;; Convert component -> virtual:
-;;; set num = num - Offset(group)
-;;; find first row in Mapping where num <= 'a'
-;;; num = (num-'b')*c + Position(group) + 'e'
-
-;;; Convert virtual -> component:
-;;; find first row in Mapping where num <= 'd'
-;;; num = num - 'e'
-;;; group_pos = num mod 'c'
-;;; num = (num / 'c') + 'b' + Offset(group_pos)
-
-;;; Easy no? :)
-;;;
-;;; Well actually, you need to keep column e offset smaller by the 'c'
-;;; column for that line, and always add 1 more when going from
-;;; component -> virtual. Otherwise you run into a problem with
-;;; unique reverse mapping.

-;;; Commentary:
-
-;; With the introduction of the `encode-time', `decode-time', and
-;; `format-time-string' functions, dealing with time became simpler in
-;; Emacs. However, parsing time strings is still largely a matter of
-;; heuristics and no common interface has been designed.
-
-;; `parse-time-string' parses a time in a string and returns a list of 9
-;; values, just like `decode-time', where unspecified elements in the
-;; string are returned as nil. `encode-time' may be applied on these
-;; valuse to obtain an internal time value.

-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/~larsi/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.
-

-@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).

-[Set] [Save] [Reset] [Done]
-@end example

-Q1.1 What is the latest version of Gnus?
-
-The latest (and greatest) version is 5.0.10. You might also run
-across something called @emph{September Gnus}. September Gnus
-is the alpha version of the next major release of Gnus. It is currently
-not stable enough to run unless you are prepared to debug lisp.

-Q1.3 Which version of Emacs do I need?
-
-At least GNU Emacs 19.28, or XEmacs 19.12 is recommended. GNU Emacs
-19.25 has been reported to work under certain circumstances, but it
-doesn't @emph{officially} work on it. 19.27 has also been reported to
-work. Gnus has been reported to work under OS/2 as well as Unix.
-
-
-@item
-Q1.4 Where is timezone.el?
-
-Upgrade to XEmacs 19.13. In earlier versions of XEmacs this file was
-placed with Gnus 4.1.3, but that has been corrected.
-
-
-@item
-Q1.5 When I run Gnus on XEmacs 19.13 I get weird error messages.
-
-You're running an old version of Gnus. Upgrade to at least version

-
-If you are reading the digest version of the list, send an e-mail message

-with @emph{unsubscribe} as the subject and you will be removed.
-
-
-@item
-Q1.7 How do I run Gnus on both Emacs and XEmacs?
-
-The basic answer is to byte-compile under XEmacs, and then you can
-run under either Emacsen. There is, however, a potential version
-problem with easymenu.el with Gnu Emacs prior to 19.29.
-
-Per Abrahamsen <abraham@@dina.kvl.dk> writes :@*
-The internal easymenu.el interface changed between 19.28 and 19.29 in
-order to make it possible to create byte compiled files that can be
-shared between Gnu Emacs and XEmacs. The change is upward
-compatible, but not downward compatible.
-This gives the following compatibility table:
-
-@example
-Compiled with: | Can be used with:
-----------------+--------------------------------------
-19.28 | 19.28 19.29
-19.29 | 19.29 XEmacs
-XEmacs | 19.29 XEmacs
-@end example
-
-If you have Gnu Emacs 19.28 or earlier, or XEmacs 19.12 or earlier, get
-a recent version of auc-menu.el from
-@file{ftp://ftp.iesd.auc.dk/pub/emacs-lisp/auc-menu.el}, and install it
-under the name easymenu.el somewhere early in your load path.

-Q1.9 Gnus hangs on connecting to NNTP server
-
-I am running XEmacs on SunOS and Gnus prints a message about Connecting
-to NNTP server and then just hangs.
-
-Ben Wing <wing@@netcom.com> writes :@*
-I wonder if you're hitting the infamous @emph{libresolv} problem.
-The basic problem is that under SunOS you can compile either
-with DNS or NIS name lookup libraries but not both. Try
-substituting the IP address and see if that works; if so, you
-need to download the sources and recompile.

-@item
-Q1.10 Mailcrypt 3.4 doesn't work
-
-This problem is verified to still exist in Gnus 5.0.9 and Mailcrypt 3.4.
-The answer comes from Peter Arius
-<arius@@immd2.informatik.uni-erlangen.de>.
-
-I found out that mailcrypt uses
-@code{gnus-eval-in-buffer-window}, which is a macro.
-It seems as if you have
-compiled mailcrypt with plain old GNUS in load path, and the XEmacs byte
-compiler has inserted that macro definition into
-@file{mc-toplev.elc}.
-The solution is to recompile @file{mc-toplev.el} with Gnus 5 in
-load-path, and it works fine.
-
-Steve Baur <steve@@miranova.com> adds :@*
-The problem also manifests itself if neither GNUS 4 nor Gnus 5 is in the
-load-path.
-
-
-@item
-Q1.11 What other packages work with Gnus?
-
-@itemize @minus
-@item
-Mailcrypt.
-
-Mailcrypt is an Emacs interface to PGP. It works, it installs
-without hassle, and integrates very easily. Mailcrypt can be
-obtained from@*
-@file{ftp://cag.lcs.mit.edu/pub/patl/mailcrypt-3.4.tar.gz}.
-
-@item
-Tools for Mime.
-
-Tools for Mime is an Emacs MUA interface to MIME. Installation is
-a two-step process unlike most other packages, so you should
-be prepared to move the byte-compiled code somewhere. There
-are currently two versions of this package available. It can
-be obtained from@*
-@file{ftp://ftp.jaist.ac.jp/pub/GNU/elisp/}.
-Be sure to apply the supplied patch. It works with Gnus through
-version 5.0.9. In order for all dependencies to work correctly
-the load sequence is as follows:
-@lisp
- (load "tm-setup")
- (load "gnus")
- (load "mime-compose")
-@end lisp
-
-@emph{NOTE:} Loading the package disables citation highlighting by
-default. To get the old behavior back, use the @kbd{M-t} command.

-Q2.2 How do I quote messages?
-
-I see lots of messages with quoted material in them. I am wondering
-how to have Gnus do it for me.
-
-This is Gnus, so there are a number of ways of doing this. You can use
-the built-in commands to do this. There are the @kbd{F} and @kbd{R}
-keys from the summary buffer which automatically include the article
-being responded to. These commands are also selectable as @i{Followup
-and Yank} and @i{Reply and Yank} in the Post menu.
-
-@kbd{C-c C-y} grabs the previous message and prefixes each line with
-@code{ail-indentation-spaces} spaces or @code{mail-yank-prefix} if that is
-non-nil, unless you have set your own @code{mail-citation-hook}, which will
-be called to do the job.
-
-You might also consider the Supercite package, which allows for pretty
-arbitrarily complex quoting styles. Some people love it, some people
-hate it.

-Q2.3 How can I keep my nnvirtual:* groups sorted?
-
-How can I most efficiently arrange matters so as to keep my nnvirtual:*

-Q4.1 What does the message ``Buffer has changed on disk'' mean in a mail
-group?
-
-Your filter program should not deliver mail directly to your folders,
-instead it should put the mail into spool files. Gnus will then move
-the mail safely from the spool files into the folders. This will
-eliminate the problem. Look it up in the manual, in the section

-Q4.2 How do you make articles un-expirable?
-
-I am using nnml to read news and have used
-@code{gnus-auto-expirable-newsgroups} to automagically expire articles
-in some groups (Gnus being one of them). Sometimes there are
-interesting articles in these groups that I want to keep. Is there any
-way of explicitly marking an article as un-expirable - that is mark it
-as read but not expirable?
-
-Use @kbd{u}, @kbd{!}, @kbd{d} or @kbd{M-u} in the summary buffer. You
-just remove the @kbd{E} mark by setting some other mark. It's not
-necessary to tick the articles.

-My problem is that I have various mail (nnml) groups generated while
-experimenting with Gnus. How do I remove them now? Setting the level to
-9 does not help. Also @code{gnus-group-check-bogus-groups} does not
-recognize them.
-
-Removing mail groups is tricky at the moment. (It's on the to-do list,
-though.) You basically have to kill the groups in Gnus, shut down Gnus,
-edit the active file to exclude these groups, and probably remove the
-nnml directories that contained these groups as well. Then start Gnus

-Q4.4 What happened to my new mail groups?

-@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

-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
-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.
-
-@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.

-also save you some time at startup. Even if this variable is
-@code{nil}, you can always subscribe to the new groups just by pressing
-@kbd{U} in the group buffer (@pxref{Group Maintenance}). This variable
-is @code{ask-server} by default. If you set this variable to

-
-@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 it's
-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.
-
-@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.
-
-
-@node Startup Files
-@section Startup Files
-@cindex startup files
-@cindex .newsrc
-@cindex .newsrc.el
-@cindex .newsrc.eld
-
-Now, you all know about the @file{.newsrc} file. All subscription
-information is traditionally stored in this file.
-
-Things got a bit more complicated with @sc{gnus}. In addition to
-keeping the @file{.newsrc} file updated, it also used a file called
-@file{.newsrc.el} for storing all the information that didn't fit into
-the @file{.newsrc} file. (Actually, it also duplicated everything in
-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
-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 making exit from Gnus faster.
-However, this will make it impossible to use other newsreaders than
-Gnus. But hey, who would want to, right?
-
-@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.
-
-
-@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.
-
-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.
-
-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.

-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

-ticked articles, in @samp{alt.fan.andrea-dworkin} (see that little
-asterisk at the beginning of the line?).
-

-You can change that format to whatever you want by fiddling with the

-@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

-even the group name. All displayed text is just window dressing, and is

-@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

-
-@vindex gnus-activate-level
-Gnus will normally just activate (i. e., query the server about) groups

-You would normally keep important groups on high levels, but that scheme

-group buffer according to how often you read groups, perhaps? Within
-reason?
-
-This is what @dfn{group score} is for. You can assign a score to each
-group. 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

-@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 paramater,
-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 adaptive score file for the group in
-question. All adaptive 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 @var{(variable 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?

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

-currently (un)subscribed. This could entail reading the active file
-from the server.
-

-add the @code{visible} element to the group parameters in question to
-get the same effect.
-
-@vindex gnus-list-groups-with-ticked-articles
-Groups that have just ticked articles in it are normally listed in the

-This is in fact how the variable @code{gnus-topic-topology} would look

-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}.

-@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.

-@code{From} header. Two pre-defined functions exist:
-@code{gnus-extract-address-components}, which is the default, quite

-

-with those specs that require it. The default is @code{""}.

-
-@vindex gnus-summary-line-format

-lines as a normal @code{format} string, with some extensions
-(@pxref{Formatting Variables}).
-
-The default string is @samp{%U%R%z%I%(%[%4L: %-20,20n%]%) %s\n}.
-
-The following format specification characters are understood:
-
-@table @samp
-@item N
-Article number.
-@item S
-Subject string.
-@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
-Full @code{From} header.
-@item n
-The name (from the @code{From} header).
-@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 address (from the @code{From} header). This works the same way as
-the @code{a} spec.
-@item L
-Number of lines in the article.
-@item c
-Number of characters in the article.
-@item I
-Indentation based on thread level (@pxref{Customizing Threading}).
-@item T
-Nothing if the article is a root and lots of spaces if it isn't (it
-pushes everything after it off the screen).
-@item [
-Opening bracket, which is normally @samp{[}, but can also be @samp{<}
-for adopted articles (@pxref{Customizing Threading}).
-@item ]
-Closing bracket, which is normally @samp{]}, but can also be @samp{>}
-for adopted articles.
-@item >
-One space for each thread level.
-@item <
-Twenty minus thread level spaces.
-@item U
-Unread.
-@item R
-Replied.
-@item i
-Score as a number (@pxref{Scoring}).
-@item z
-@vindex gnus-summary-zcore-fuzz
-Zcore, @samp{+} if above the default level and @samp{-} if below the
-default level. If the difference between
-@code{gnus-summary-default-level} and the score is less than
-@code{gnus-summary-zcore-fuzz}, this spec will not be used.
-@item V
-Total thread score.
-@item x
-@code{Xref}.
-@item D
-@code{Date}.
-@item d
-The @code{Date} in @code{DD-MMM} format.
-@item o
-The @code{Date} in @var{YYYYMMDD}@code{T}@var{HHMMSS} format.
-@item M
-@code{Message-ID}.
-@item r
-@code{References}.
-@item t
-Number of articles in the current sub-thread. Using this spec will slow
-down summary buffer generation somewhat.
-@item e
-An @samp{=} (@code{gnus-not-empty-thread-mark}) will be displayed if the
-article has any children.
-@item P
-The line number.
-@item O
-Download mark.
-@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 the current header as
-argument. The function should return a string, which will be inserted
-into the summary just like information from any other summary specifier.
-@end table
-
-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
-variable-length spec. Well, you might not be arrested, but your summary
-buffer will look strange, which is bad enough.
-
-The smart choice is to have these specs as far to the left as possible.
-(Isn't that the case with everything, though? But I digress.)

-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

-@cindex canceling articles
-@cindex superseding articles
-
-Have you ever written something, and then decided that you really,
-really, really wish you hadn't posted that?
-
-Well, you can't cancel mail, but you can cancel posts.
-
-@findex gnus-summary-cancel-article
-@kindex C (Summary)
-@c @icon{gnus-summary-cancel-article}
-Find the article you wish to cancel (you can only cancel your own
-articles, so don't try any funny stuff). Then press @kbd{C} or @kbd{S
-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 cancelling. 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)
-Go to the original article and press @kbd{S s}
-(@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.

-other.
-
-@table @samp
-@item !
-@vindex gnus-ticked-mark
-Marked as ticked (@code{gnus-ticked-mark}).
-
-@dfn{Ticked articles} are articles that will remain visible always. If
-you see an article that you find interesting, or you want to put off
-reading it, or replying to it, until sometime later, you'd typically
-tick it. However, articles can be expired, so if you want to keep an
-article forever, you'll have to make it persistent (@pxref{Persistent
-Articles}).
-
-@item ?
-@vindex gnus-dormant-mark
-Marked as dormant (@code{gnus-dormant-mark}).
-
-@dfn{Dormant articles} will only appear in the summary buffer if there
-are followups to it. If you want to see them even if they don't have
-followups, you can use the @kbd{/ D} command (@pxref{Limiting}).
-
-@item SPACE

-
-One more special mark, though:
-
-@table @samp
-@item E
-@vindex gnus-expirable-mark
-Marked as expirable (@code{gnus-expirable-mark}).
-
-Marking articles as @dfn{expirable} (or have them marked as such
-automatically) doesn't make much sense in normal groups---a user doesn't
-control expiring of news articles, but in mail groups, for instance,
-articles marked as @dfn{expirable} can be deleted by Gnus at
-any time.
-@end table
-
-
-@node Other Marks

-@cindex process mark
-@cindex bookmarks
-
-There are some marks that have nothing to do with whether the article is

-
-@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}
-

-(@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.

-@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 propagration 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 typicall 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.

-@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
-@iflatex
-\gnusfigure{The Summary Buffer}{390}{
-\put(0,0){\epsfig{figure=tmp/summary-adopt.ps,width=7.5cm}}

-
-@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}).
-
-@item gnus-simplify-subject-fuzzy-regexp

-
-@item gnus-simplify-ignored-prefixes

-
-@item gnus-simplify-subject-functions
-@vindex gnus-simplify-subject-functions
-If non-@code{nil}, this variable overrides
-@code{gnus-summary-gather-subject-limit}. This variable should be a
-list of functions to apply to the @code{Subject} string iteratively to
-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
-Strip the leading @samp{Re:}.
-
-@item gnus-simplify-subject-fuzzy
-@findex gnus-simplify-subject-fuzzy
-Simplify fuzzily.
-
-@item gnus-simplify-whitespace
-@findex gnus-simplify-whitespace

-@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
-Gnus gathers threads by looking at @code{Subject} headers. This means
-that totally unrelated articles may end up in the same ``thread'', which
-is confusing. An alternate approach is to look at all the
-@code{Message-ID}s in all the @code{References} headers to find matches.
-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
-cholera:
-
-@table @code
-@item gnus-gather-threads-by-subject
-@findex gnus-gather-threads-by-subject
-This function is the default gathering function and looks at

-

-@findex gnus-gather-threads-by-references
-This function looks at @code{References} headers exclusively.
-@end table

-@node Filling In Threads
-@subsubsection Filling In Threads
-
-@table @code
-@item gnus-fetch-old-headers
-@vindex 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.
-
-This variable can also be set to @code{invisible}. This won't have any
-visible effects, but is useful if you use the @kbd{A T} command a lot
-(@pxref{Finding the Parent}).
-
-@item gnus-build-sparse-threads
-@vindex gnus-build-sparse-threads
-Fetching old headers can be slow. A low-rent similar effect can be
-gotten by setting this variable to @code{some}. Gnus will then look at
-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
-@code{nil} by default.

-@vindex gnus-thread-sort-functions
-If you are using a threaded summary display, you can sort the threads by
-setting @code{gnus-thread-sort-functions}, which is a list of functions.
-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 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
- 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)
- (not (gnus-thread-sort-by-number t1 t2)))
- gnus-thread-sort-by-score))
-@end lisp
-
-@vindex gnus-thread-score-function
-The function in the @code{gnus-thread-score-function} variable (default
-@code{+}) is used for calculating the total score of a thread. Useful
-functions might be @code{max}, @code{min}, or squared means, or whatever
-tickles your fancy.

-@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
-Remove articles when they are read.
-
-@item exit
-Remove articles when exiting the group.
-@end table
-
-The default value is @code{(read exit)}.
-
-@vindex gnus-use-header-prefetch
-If @code{gnus-use-header-prefetch} is non-@code{nil}, prefetch articles
-from the next group.

-@node Article Caching
-@section Article Caching
-@cindex article caching
-@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
-It is likely that you do not want caching on some 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 the @code{gnus-uncacheable-groups} regexp to
-@samp{^nnml}, for instance. This variable is @code{nil} by
-default.
-
-@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
-gnus-cache-generate-nov-databases} will (re)build all the @sc{nov}
-files, and @kbd{gnus-cache-generate-active} will (re)generate the active
-file.
-
-
-@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
-bound before exploding and taking your machine down with you. I put
-that in there just to keep y'all on your toes.
-
-This variable is @code{nil} by default.
-
-
-@node Saving Articles

-Gnus can save articles in a number of ways. Below is the documentation
-for saving articles in a fairly straight-forward fashion (i.e., little
-processing of the article is done before it is saved). For a different
-approach (uudecoding, unsharing) you should use @code{gnus-uu}
-(@pxref{Decoding Articles}).
-
-@vindex gnus-save-all-headers
-If @code{gnus-save-all-headers} is non-@code{nil}, Gnus will not delete
-unwanted headers before saving the article.

-All these commands use the process/prefix convention

-the @code{gnus-prompt-before-saving} variable, which is @code{always} by
-default, giving you that excessive prompting action you know and
-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

-
-@item gnus-summary-save-body-in-file

-@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 toplevel 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 toplevel directory as the argument (@file{~/News/}). Then just walk
-around to the groups/directories with @code{nneething}.
-
-
-@node Decoding Articles
-@section Decoding Articles
-@cindex decoding articles

-Sometime users post articles (or series of articles) that have been

-@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{#}.

-@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-pseudo-asynchronously
-If @code{gnus-view-pseudo-asynchronously} is @code{nil}, Emacs will wait
-until the viewing is done before proceeding.
-
-@vindex gnus-view-pseudos
-If @code{gnus-view-pseudos} is @code{automatic}, Gnus will not insert
-the pseudo-articles into the summary buffer, but view them
-immediately. If this variable is @code{not-confirm}, the user won't even
-be asked for a confirmation before viewing is done.
-
-@vindex gnus-view-pseudos-separately
-If @code{gnus-view-pseudos-separately} is non-@code{nil}, one
-pseudo-article will be created for each file to be viewed. If
-@code{nil}, all files that use the same viewing command will be given as
-a list of parameters to that command.

-Unreadable articles that tell you to read them with Caesar rotate or rot13.
-(Typically offensive jokes and such.)
-
-It's commonly called ``rot13'' because each letter is rotated 13
-positions in the alphabet, e. g. @samp{B} (letter #2) -> @samp{O} (letter
-#15). It is sometimes referred to as ``Caesar rotate'' because Caesar
-is rumoured to have employed this form of, uh, somewhat weak encryption.

-@code{From} header. (It's nicer if XEmacs has been compiled with X-Face
-support---that will make display somewhat faster. If there's no native
-X-Face support, Gnus will try to convert the @code{X-Face} header using

-be nice if Gnus could just fetch whatever it is that people talk about
-with the minimum of fuzz when you hit @kbd{RET} or use the middle mouse
-button on these references.
-
-Gnus adds @dfn{buttons} to certain standard references by default:
-Well-formed URLs, mail addresses and Message-IDs. This is controlled by
-two variables, one that handles article bodies and one that handles
-article heads:
-
-@table @code
-
-@item gnus-button-alist
-@vindex gnus-button-alist
-This is an alist where each entry has this form:
-
-@lisp
-(REGEXP BUTTON-PAR USE-P FUNCTION DATA-PAR)
-@end lisp
-
-@table @var
-
-@item regexp
-All text that match this regular expression will be considered an
-external reference. Here's a typical regexp that matches embedded URLs:
-@samp{<URL:\\([^\n\r>]*\\)>}.
-
-@item button-par
-Gnus has to know which parts of the matches is to be highlighted. This
-is a number that says what sub-expression of the regexp is to be
-highlighted. If you want it all highlighted, you use 0 here.
-
-@item use-p
-This form will be @code{eval}ed, and if the result is non-@code{nil},
-this is considered a match. This is useful if you want extra sifting to
-avoid false matches.
-
-@item function
-This function will be called when you click on this button.
-
-@item data-par
-As with @var{button-par}, this is a sub-expression number, but this one
-says which part of the match is to be sent as data to @var{function}.
-
-@end table
-
-So the full entry for buttonizing URLs is then
-
-@lisp
-("<URL:\\([^\n\r>]*\\)>" 0 t gnus-button-url 1)
-@end lisp
-
-@item gnus-header-button-alist
-@vindex gnus-header-button-alist
-This is just like the other alist, except that it is applied to the

-used to say what headers to apply the buttonize coding to:
-
-@lisp
-(HEADER REGEXP BUTTON-PAR USE-P FUNCTION DATA-PAR)
-@end lisp
-
-@var{HEADER} is a regular expression.
-
-@item gnus-button-url-regexp

-@item
-If it is a floating point number, no signature may be longer (in lines)

-@item
-If it is a function, the function will be called without any parameters,

-@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

-
-@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-summary-mark-as-processable
-Pick the article on the current line
-(@code{gnus-summary-mark-as-processable}). If given a numerical prefix,
-go to that 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

-is @samp{%(%[%3,3n%]%)}, which displays the first three characters of
-the name of the poster. It is vital that all nodes are of the same
-length, so you @emph{must} use @samp{%4,4n}-like specifiers.
-
-Valid specs are:
-
-@table @samp
-@item n
-The name of the poster.
-@item f
-The @code{From} header.
-@item N
-The number of the article.

-@item gnus-tree-brackets
-@vindex gnus-tree-brackets
-This is used for differentiating between ``real'' articles and
-``sparse'' articles. The format is @var{((real-open . real-close)
-(sparse-open . sparse-close) (dummy-open . dummy-close))}, and the
-default is @code{((?[ . ?]) (?( . ?)) (?@{ . ?@}) (?< . ?>))}.
-
-@item gnus-tree-parent-child-edges

-@vindex gnus-tree-minimize-window
-If this variable is non-@code{nil}, Gnus will try to keep the tree
-buffer as small as possible to allow more room for the other Gnus
-windows. If this variable is a number, the tree buffer will never be
-higher than that number. The default is @code{t}. Note that if you
-have several windows displayed side-by-side in a frame and the tree

- | \[Jan]
- | \[odd]-[Eri]
- | \(***)-[Eri]
- | \[odd]-[Paa]
- \[Bjo]

-
-@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
-suppression list. The default is 10000.
-
-@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
-to you to figure out, I think.

-The top section of each article is the @dfn{head}. (The rest is the
-@dfn{body}, but you may have guessed that already.)
-
-@vindex gnus-show-all-headers
-There is a lot of useful information in the head: the name of the person
-who wrote the article, the date it was written and the subject of the
-article. That's well and nice, but there's also lots of information
-most people do not want to see---what systems the article has passed
-through before reaching you, the @code{Message-ID}, the
-@code{References}, etc. ad nauseum---and you'll probably want to get rid
-of some of those lines. If you want to keep all those lines in the
-article buffer, you can set @code{gnus-show-all-headers} to @code{t}.
-
-Gnus provides you with two variables for sifting headers:
-
-@table @code
-
-@item gnus-visible-headers
-@vindex gnus-visible-headers
-If this variable is non-@code{nil}, it should be a regular expression
-that says what headers you wish to keep in the article buffer. All
-headers that do not match this variable will be hidden.
-
-For instance, if you only want to see the name of the person who wrote
-the article and the subject, you'd say:
-
-@lisp
-(setq gnus-visible-headers "^From:\\|^Subject:")
-@end lisp
-
-This variable can also be a list of regexps to match headers to
-remain visible.
-
-@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
-be removed.
-
-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-article-display-hook
-@vindex gnus-boring-article-headers
-You can hide further boring headers by entering
-@code{gnus-article-hide-boring-headers} into
-@code{gnus-article-display-hook}. 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 newsgroups
-Remove the @code{Newsgroups} header if it only contains the current group
-name.
-@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 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 first elements, you could say something like;
-
-@lisp
-(setq gnus-boring-article-headers
- '(empty newsgroups 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-show-mime
-@vindex gnus-show-mime-method
-@vindex gnus-strict-mime
-@findex metamail-buffer
-Gnus handles @sc{mime} by pushing the articles through
-@code{gnus-show-mime-method}, which is @code{metamail-buffer} by
-default. This function calls the external @code{metamail} program to
-actually do the work. One common problem with this program is that is
-thinks that it can't display 8-bit things in the Emacs buffer. To tell
-it the truth, put something like the following in your
-@file{.bash_profile} file. (You do use @code{bash}, don't you?)
-
-@example
-export MM_CHARSET="iso-8859-1"
-@end example
-
-For more information on @code{metamail}, see its manual page.
-
-Set @code{gnus-show-mime} to @code{t} if you want to use
-@sc{mime} all the time. However, if @code{gnus-strict-mime} is
-non-@code{nil}, the @sc{mime} method will only be used if there are
-@sc{mime} headers in the article. If you have @code{gnus-show-mime}
-set, then you'll see some unfortunate display glitches in the article
-buffer. These can't be avoided.
-
-It might be best to just use the toggling functions from the summary
-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.

-
-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.

-@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

-(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" (current-time))))))
-@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.

-@c
-@c All them variables, they make my head swim.
-@c
-@c So what if you want a different @code{Organization} and signature based
-@c on what groups you post to? And you post both from your home machine
-@c and your work machine, and you want different @code{From} lines, and so
-@c on?
-@c
-@c @vindex gnus-posting-styles
-@c One way to do stuff like that is to write clever hooks that change the
-@c variables you need to have changed. That's a bit boring, so somebody
-@c came up with the bright idea of letting the user specify these things in
-@c a handy alist. Here's an example of a @code{gnus-posting-styles}
-@c variable:
-@c
-@c @lisp
-@c ((".*"
-@c (signature . "Peace and happiness")
-@c (organization . "What me?"))
-@c ("^comp"
-@c (signature . "Death to everybody"))
-@c ("comp.emacs.i-love-it"
-@c (organization . "Emacs is it")))
-@c @end lisp
-@c
-@c As you might surmise from this example, this alist consists of several
-@c @dfn{styles}. Each style will be applicable if the first element
-@c ``matches'', in some form or other. The entire alist will be iterated
-@c over, from the beginning towards the end, and each match will be
-@c applied, which means that attributes in later styles that match override
-@c the same attributes in earlier matching styles. So
-@c @samp{comp.programming.literate} will have the @samp{Death to everybody}
-@c signature and the @samp{What me?} @code{Organization} header.
-@c
-@c The first element in each style is called the @code{match}. If it's a
-@c string, then Gnus will try to regexp match it against the group name.
-@c If it's a function symbol, that function will be called with no
-@c arguments. If it's a variable symbol, then the variable will be
-@c referenced. If it's a list, then that list will be @code{eval}ed. In
-@c any case, if this returns a non-@code{nil} value, then the style is said
-@c to @dfn{match}.
-@c
-@c Each style may contain a arbitrary amount of @dfn{attributes}. Each
-@c attribute consists of a @var{(name . value)} pair. The attribute name
-@c can be one of @code{signature}, @code{organization} or @code{from}. The
-@c attribute name can also be a string. In that case, this will be used as
-@c a header name, and the value will be inserted in the headers of the
-@c article.
-@c
-@c The attribute value can be a string (used verbatim), a function (the
-@c return value will be used), a variable (its value will be used) or a
-@c list (it will be @code{eval}ed and the return value will be used).
-@c
-@c So here's a new example:
-@c
-@c @lisp
-@c (setq gnus-posting-styles
-@c '((".*"
-@c (signature . "~/.signature")
-@c (from . "user@@foo (user)")

-@c ((equal (system-name) "gnarly")
-@c (signature . my-quote-randomizer))
-@c (posting-from-work-p
-@c (signature . "~/.work-signature")
-@c (from . "user@@bar.foo (user)")
-@c (organization . "Important Work, Inc"))

-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

-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
-@var{(variable 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

-
-@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"))
-@end lisp
-
-
-@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
-
-@item O
-@kindex O (Server)

-
-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}
-server:
-
-@table @code
-
-@item nntp-server-opened-hook
-@vindex nntp-server-opened-hook
-@cindex @sc{mode reader}
-@cindex authinfo
-@cindex authentification
-@cindex nntp 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 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}, and @samp{password}.
-
-@end enumerate
-
-Here's an example file:
-
-@example
-machine news.uio.no login larsi password geheimnis
-machine nntp.ifi.uio.no login larsi
-@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.
-
-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

-@c described above.

-"XOVERVIEW")}.
-
-@item nntp-nov-gap
-@vindex nntp-nov-gap
-@code{nntp} normally sends just one big request for @sc{nov} lines to
-the server. The server responds with one huge list of lines. However,
-if you have read articles 2-5000 in the group, and only want to read
-article 1 and 5001, that means that @code{nntp} will fetch 4999 @sc{nov}
-lines that you will not need. This variable says how
-big a gap between two consecutive articles is allowed to be before the
-@code{XOVER} request is split into several request. Note that if your
-network is fast, setting this variable to a really small number means
-that fetching will probably be slower. If this variable is @code{nil},
-@code{nntp} will never split requests. The default is 5.

-@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
-
-If the first element is the special symbol @code{junk}, then messages
-that match the regexp will disappear into the aether. Use with
-extreme caution.
-
-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
-can use the @kbd{M-x nnmail-split-history} command.
-
-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
-month's rent money.

-
-@node Mail Backend Variables
-@subsection Mail Backend Variables
-
-These variables are (for the most part) pertinent to all the various
-mail backends.
-
-@table @code
-@vindex nnmail-read-incoming-hook
-@item nnmail-read-incoming-hook
-The mail backends all call this hook after reading new mail. You can
-use this hook to notify any mail watch programs, if you want to.
-
-@vindex nnmail-spool-file
-@item nnmail-spool-file
-@cindex POP mail
-@cindex MAILHOST
-@cindex movemail
-@vindex nnmail-pop-password
-@vindex nnmail-pop-password-required
-The backends will look for new mail in this file. If this variable is
-@code{nil}, the mail backends will never attempt to fetch mail by
-themselves. If you are using a POP mail server and your name is
-@samp{larsi}, you should set this variable to @samp{po:larsi}. If
-your name is not @samp{larsi}, you should probably modify that
-slightly, but you may have guessed that already, you smart & handsome
-devil! You can also set this variable to @code{pop}, and Gnus will try
-to figure out the POP mail string by itself. In any case, Gnus will
-call @code{movemail} which will contact the POP server named in the
-@code{MAILHOST} environment variable. If the POP server needs a
-password, you can either set @code{nnmail-pop-password-required} to
-@code{t} and be prompted for the password, or set
-@code{nnmail-pop-password} to the password itself.
-
-@code{nnmail-spool-file} can also be a list of mailboxes.
-
-Your Emacs has to have been configured with @samp{--with-pop} before
-compilation. This is the default, but some installations have it
-switched off.
-
-When you use a mail backend, Gnus will slurp all your mail from your
-inbox and plonk it down in your home directory. Gnus doesn't move any
-mail if you're not using a mail backend---you have to do a lot of magic
-invocations first. At the time when you have finished drawing the
-pentagram, lightened the candles, and sacrificed the goat, you really
-shouldn't be too surprised when Gnus moves your mail.
-
-@vindex nnmail-use-procmail
-@vindex nnmail-procmail-suffix
-@item nnmail-use-procmail
-If non-@code{nil}, the mail backends will look in
-@code{nnmail-procmail-directory} for incoming mail. All the files in
-that directory that have names ending in @code{nnmail-procmail-suffix}
-will be considered incoming mailboxes, and will be searched for new
-mail.
-
-@vindex nnmail-crash-box
-@item nnmail-crash-box
-When a mail backend reads a spool file, mail is first moved to this
-file, which is @file{~/.gnus-crash-box} by default. If this file
-already exists, it will always be read (and incorporated) before any
-other spool files.
-
-@vindex nnmail-prepare-incoming-hook
-@item nnmail-prepare-incoming-hook
-This is run in a buffer that holds all the new incoming mail, and can be
-used for, well, anything, really.
-
-@vindex nnmail-split-hook
-@item nnmail-split-hook
-@findex article-decode-rfc1522
-@findex RFC1522 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-rfc1522}
-is one likely function to add to this hook.
-
-@vindex nnmail-pre-get-new-mail-hook
-@vindex nnmail-post-get-new-mail-hook
-@item nnmail-pre-get-new-mail-hook
-@itemx nnmail-post-get-new-mail-hook
-These are two useful hooks executed when treating new incoming
-mail---@code{nnmail-pre-get-new-mail-hook} (is called just before
-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
-default file modes the new mail files get:
-
-@lisp
-(add-hook 'gnus-pre-get-new-mail-hook
- (lambda () (set-default-file-modes 511)))
-
-(add-hook 'gnus-post-get-new-mail-hook
- (lambda () (set-default-file-modes 551)))
-@end lisp
-
-@item nnmail-tmp-directory
-@vindex nnmail-tmp-directory
-This variable says where to move incoming mail to -- while processing
-it. This is usually done in the same directory that the mail backend
-inhabits (e.g., @file{~/Mail/}), but if this variable is non-@code{nil},
-it will be used instead.
-
-@item nnmail-movemail-program
-@vindex nnmail-movemail-program
-This program is executed to move mail from the user's inbox to her home
-directory. The default is @samp{movemail}.
-
-This can also be a function. In that case, the function will be called
-with two parameters -- the name of the inbox, and the file to be moved
-to.
-
-@item nnmail-delete-incoming
-@vindex nnmail-delete-incoming
-@cindex incoming mail files
-@cindex deleting incoming files
-If non-@code{nil}, the mail backends will delete the temporary incoming
-file after splitting mail into the proper groups. This is @code{t} by
-default.
-
-@c This is @code{nil} by
-@c default for reasons of security.
-
-@c Since Red Gnus is an alpha release, it is to be expected to lose mail.
-(No Gnus release since (ding) Gnus 0.10 (or something like that) have
-lost mail, I think, but that's not the point. (Except certain versions
-of Red Gnus.)) By not deleting the Incoming* files, one can be sure not
-to lose mail -- if Gnus totally whacks out, one can always recover what
-was lost.
-
-You may delete the @file{Incoming*} files at will.
-
-@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
-names. Groups like @samp{mail.misc} will end up in directories
-(assuming use of @code{nnml} backend) or files (assuming use of
-@code{nnfolder} backend) like @file{mail.misc}. If it is @code{nil},
-the same group will end up in @file{mail/misc}.
-
-@item nnmail-delete-file-function
-@vindex nnmail-delete-file-function
-@findex delete-file
-Function called to delete files. It is @code{delete-file} by default.
-
-@item nnmail-cache-accepted-message-ids
-@vindex nnmail-cache-accepted-message-ids
-If non-@code{nil}, put the @code{Message-ID}s of articles imported into
-the backend (via @code{Gcc}, for instance) into the mail duplication
-discovery cache. The default is @code{nil}.
-
-@end table

-
-@node Fancy Mail Splitting
-@subsection Fancy Mail Splitting
-@cindex mail splitting
-@cindex fancy mail splitting
-
-@vindex nnmail-split-fancy
-@findex nnmail-split-fancy
-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
-;; the ordinary groups. Warnings are put in a separate group
-;; from real errors.
-(| ("from" mail (| ("subject" "warn.*" "mail.warning")
- "mail.misc"))
- ;; Non-error messages are crossposted to all relevant
- ;; groups, but we don't crosspost between the group for the
- ;; (ding) list and the group for other (ding) related mail.
- (& (| (any "ding@@ifi\\.uio\\.no" "ding.list")
- ("subject" "ding" "ding.misc"))
- ;; Other mailing lists...
- (any "procmail@@informatik\\.rwth-aachen\\.de" "procmail.list")
- (any "SmartList@@informatik\\.rwth-aachen\\.de" "SmartList.list")
- ;; People...
- (any "larsi@@ifi\\.uio\\.no" "people.Lars_Magne_Ingebrigtsen"))
- ;; Unmatched mail goes to the catch all group.
- "misc.misc")
-@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.
-
-@item
-@var{(FIELD VALUE SPLIT)}: If the split is a list, the first element of
-which is a string, then store the message as specified by SPLIT, if
-header FIELD (a regexp) contains VALUE (also a regexp).
-
-@item
-@var{(| SPLIT...)}: If the split is a list, and the first element is
-@code{|} (vertical bar), then process each SPLIT until one of them
-matches. A SPLIT is said to match if it will cause the mail message to
-be stored in one or more groups.
-
-@item
-@var{(& SPLIT...)}: If the split is a list, and the first element is
-@code{&}, then process all SPLITs in the list.
-
-@item
-@code{junk}: If the split is the symbol @code{junk}, then don't save
-this message.
-
-@item
-@var{(: function arg1 arg2 ...)}: 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 SPLIT.
-
-@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
-substitions in the group names), you can say things like:
-
-@example
-(any "debian-\\(\\w*\\)@@lists.debian.org" "mail.debian.\\1")
-@end example
-
-@node Mail and Procmail
-@subsection Mail and Procmail
-@cindex procmail
-
-@cindex slocal
-@cindex elm
-Many people use @code{procmail} (or some other mail filter program or
-external delivery agent---@code{slocal}, @code{elm}, etc) to split
-incoming mail into groups. If you do that, you should set
-@code{nnmail-spool-file} to @code{procmail} to ensure that the mail
-backends never ever try to fetch mail by themselves.
-
-If you have a combined @code{procmail}/POP/mailbox setup, you can do
-something like the following:
-
-@vindex nnmail-use-procmail
-@lisp
-(setq nnmail-use-procmail t)
-(setq nnmail-spool-file
- '("/usr/spool/mail/my-name" "po:my-name"))
-@end lisp
-
-This also means that you probably don't want to set
-@code{nnmail-split-methods} either, which has some, perhaps, unexpected
-side effects.
-
-When a mail backend is queried for what groups it carries, it replies
-with the contents of that variable, along with any groups it has figured
-out that it carries by other means. None of the backends, except
-@code{nnmh}, actually go out to the disk and check what groups actually
-exist. (It's not trivial to distinguish between what the user thinks is
-a basis for a newsgroup and what is just a plain old file or directory.)
-
-This means that you have to tell Gnus (and the backends) by hand what
-groups exist.
-
-Let's take the @code{nnmh} backend as an example:
-
-The folders are located in @code{nnmh-directory}, say, @file{~/Mail/}.
-There are three folders, @file{foo}, @file{bar} and @file{mail.baz}.
-
-Go to the group buffer and type @kbd{G m}. When prompted, answer
-@samp{foo} for the name and @samp{nnmh} for the method. Repeat
-twice for the two other groups, @samp{bar} and @samp{mail.baz}. Be sure
-to include all your mail groups.
-
-That's it. You are now set to read your mail. An active file for this
-method will be created automatically.
-
-@vindex nnmail-procmail-suffix
-@vindex nnmail-procmail-directory
-If you use @code{nnfolder} or any other backend that store more than a
-single article in each file, you should never have procmail add mails to
-the file that Gnus sees. Instead, procmail should put all incoming mail
-in @code{nnmail-procmail-directory}. To arrive at the file name to put
-the incoming mail in, append @code{nnmail-procmail-suffix} to the group
-name. The mail backends will read the mail from these files.
-
-@vindex nnmail-resplit-incoming
-When Gnus reads a file called @file{mail.misc.spool}, this mail will be
-put in the @code{mail.misc}, as one would expect. However, if you want
-Gnus to split the mail the normal way, you could set
-@code{nnmail-resplit-incoming} to @code{t}.
-
-@vindex nnmail-keep-last-article
-If you use @code{procmail} to split things directly into an @code{nnmh}
-directory (which you shouldn't do), you should set
-@code{nnmail-keep-last-article} to non-@code{nil} to prevent Gnus from
-ever expiring the final article (i.e., the article with the highest

-@node Incorporating Old Mail
-@subsection Incorporating Old Mail
-
-Most people have lots of old mail stored in various file formats. If
-you have set up Gnus to read mail using one of the spiffy Gnus mail
-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.

-@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. 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
-

-@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!

-
-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

-weeks. If this is no problem for you, and it isn't a problem for you

-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

-@subsection Directory Groups
-@cindex nndir
-@cindex directory groups
-
-If you have a directory that has lots of articles in separate files in
-it, you might treat it as a newsgroup. The files have to have numerical
-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

-@item nneething-exclude-files
-@vindex nneething-exclude-files
-All files that match this regexp will be ignored. Nice to use to exclude

-@code{nndoc} is a cute little thing that will let you read a single file
-as a newsgroup. Several files types are supported:
-
-@table @code
-@cindex babyl
-@cindex rmail mbox
-
-@item babyl
-The babyl (rmail) mail box.
-@cindex mbox
-@cindex Unix mbox

-
-@item standard-digest
-The standard (RFC 1153) digest format.
-
-@item slack-digest
-Non-standard digest format---matches most things, but does it badly.
-@end table
-
-You can also use the special ``file type'' @code{guess}, which means
-that @code{nndoc} will try to guess what file type it is looking at.
-@code{digest} means that @code{nndoc} should guess what digest type the
-file is.
-
-@code{nndoc} will not try to change the file or insert any extra headers into
-it---it will simply, like, let you use the file as the basis for a
-group. And that's it.
-
-If you have some old archived articles that you want to insert into your
-new & spiffy Gnus mail backend, @code{nndoc} can probably help you with
-that. Say you have an old @file{RMAIL} file with mail that you now want
-to split into your new @code{nnml} groups. You look at that file using
-@code{nndoc} (using the @kbd{G f} command in the group buffer
-(@pxref{Foreign Groups})), set the process mark on all the articles in
-the buffer (@kbd{M P b}, for instance), and then re-spool (@kbd{B r})
-using @code{nnml}. If all goes well, all the mail in the @file{RMAIL}
-file is now also stored in lots of @code{nnml} directories, and you can
-delete that pesky @file{RMAIL} file. If you have the guts!

-@node Document Server Internals
-@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 a 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.

-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.

-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

-@cindex nnvirtual
-@cindex virtual 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$\\|^rec\\.dworkin.*")
-@end lisp
-
-The component groups can be native or foreign; everything should work
-smoothly, but if your computer explodes, it was probably my fault.
-
-Collecting the same group from several servers might actually be a good
-idea if users have set the Distribution header to limit distribution.
-If you would like to read @samp{soc.motss} both from a server in Japan
-and a server in Norway, you could use the following as the group regexp:
-
-@example
-"^nntp\\+some\\.server\\.jp:soc\\.motss$\\|^nntp\\+some\\.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.

-@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.
-
-@itemize @bullet
-@item
-First, set up Gnus as you would do if you were running it on a machine
-that has full connection to the net. Go ahead. I'll still be waiting
-here.
-
-@item
-Then, put the following magical incantation at the end of your
-@file{.gnus.el} file:
-
-@lisp
-(gnus-agentize)
-@end lisp
-@end itemize
-
-That's it. Gnus is now an ``offline'' newsreader.
-
-Of course, to use it as such, you have to learn a few new commands.

-@node Agent Basics
-@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 continously.
-
-@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.
-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 wholly unrelated to normal scores.)
-@end enumerate
-
-A predicate consists 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.
-
-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{From}, @code{Subject},
-@code{Date}, @code{Xref}, @code{Lines}, @code{Chars}, @code{Message-ID},
-and @code{References}.
-
-
-@node The Category Buffer

-;;; Define how Gnus is to fetch news. We do this over NNTP

-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

-The score commands that alter score entries do not actually modify real

-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

-
-@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 Xref line---i.e., the cross-posting line.
-
-@item t
-Score on thread---the References line.
-
-@item d
-Score on the date.
-
-@item l
-Score on the number of lines.

-@item f
-Score on followups.
-
-@item b
-Score on the body.
-
-@item h
-Score on the head.
-@end table
-

-The third key is the match type. Which match types are valid depends on
-what headers you are scoring on.
-

-
-@table @kbd
-
-@item e

-@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

-@table @code
-
-@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 you 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.
-
-@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.
-
-@end table
-
-
-@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))
- ("subject"
- ("Ding is Badd" nil 728373))
- ("xref"
- ("alt.politics" -1000 728372 s))
- ("lines"
- (2 -100 nil <))
- (mark 0)
- (expunge -1000)
- (mark-and-expunge -10)
- (read-only nil)
- (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{<=}. 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.)
-@end table
-@end enumerate
-
-@cindex Score File Atoms
-@item mark
-The value of this entry should be a number. Any articles with a score
-lower than this number will be marked as read.
-
-@item expunge
-The value of this entry should be a number. Any articles with a score
-lower than this number will be removed from the summary buffer.
-
-@item mark-and-expunge
-The value of this entry should be a number. Any articles with a score
-lower than this number will be marked as read and removed from the
-summary buffer.
-
-@item thread-mark-and-expunge
-The value of this entry should be a number. All articles that belong to
-a thread that has a total score below this number will be marked as read
-and removed from the summary buffer. @code{gnus-thread-score-function}
-says how to compute the total score for a thread.
-
-@item files
-The value of this entry should be any number of file names. These files
-are assumed to be score files as well, and will be loaded the same way
-this one was.
-
-@item exclude-files
-The clue of this entry should be any number of files. These files will
-not be loaded, even though they would normally be so, for some reason or
-other.
-
-@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.
-@end table
-
-
-@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
-(@code{gnus-score-edit-done}).
-
-@item C-c C-d
-@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}.
-
-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
-@var{(regexp 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:
-
-@lisp
-(setq gnus-home-score-file
- 'gnus-hierarchial-home-score-file)
-@end lisp
-
-This is a ready-made function provided for your convenience.
-
-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.

-
-@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 has a score 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.

-
-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
-that isn't a very good idea.
-
-Normal kill files look like this:
-
-@lisp
-(gnus-kill "From" "Lars Ingebrigtsen")
-(gnus-kill "Subject" "ding")
-(gnus-expunge "X")
-@end lisp
-
-This will mark every article written by me as read, and remove the
-marked articles from the summary buffer. Very useful, you'll agree.
-
-Other programs use a totally different kill file syntax. If Gnus
-encounters what looks like a @code{rn} kill file, it will take a stab at
-interpreting it.

-@vindex grouplens-prediction-display
-In either case, GroupLens gives you a few choices for how you would like

-Scoring on Subjects and From headers is nice enough, but what if you're
-really interested in what a person has to say only when she's talking
-about a particular subject? Or what if you really don't want to
-read what person A has to say when she's following up to person B, but
-want to read what she says when she's following up to person C?
-
-By using advanced scoring rules you may create arbitrarily complex
-scoring patterns.

-@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
-
-However, when he responds to things written by Reig Eigil Logge, you
-really don't want to read what he's written:
-
-@example
-((&
- ("from" "Lars Ingebrigtsen")
- (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"))
- ("body" "white.*socks"))
- 1000)
-@end example
-
-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")))

-@cindex decays
-
-You may find that your scores have a tendency to grow without
-bounds, especially if you're using adaptive scoring. If scores get too
-big, they lose all meaning---they simply max out and it's difficult to
-use them in any sensible way.
-
-@vindex gnus-decay-scores
-@findex gnus-decay-score
-@vindex gnus-score-decay-function
-Gnus provides a mechanism for decaying scores to help with this problem.
-When score files are loaded and @code{gnus-decay-scores} is
-non-@code{nil}, Gnus will run the score files through the decaying
-mechanism thereby lowering the scores of all non-permanent score rules.
-The decay itself if performed by the @code{gnus-score-decay-function}
-function, which is @code{gnus-decay-score} by default. Here's the
-definition of that function:
-
-@lisp
-(defun gnus-decay-score (score)
- "Decay SCORE according to `gnus-score-decay-constant' and `gnus-score-decay-scale'."
- (floor
- (- score
- (* (if (< score 0) 1 -1)
- (min (abs score)
- (max gnus-score-decay-constant
- (* (abs score)
- gnus-score-decay-scale)))))))
-@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.

-@node Process/Prefix
-@section Process/Prefix
-@cindex process/prefix convention
-
-Many functions, among them functions for moving, decoding and saving
-articles, use what is known as the @dfn{Process/Prefix convention}.
-
-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
-articles, starting with the current one. If the numeric prefix is
-negative, perform the operation on the previous N articles, starting
-with the current one.
-
-@vindex transient-mark-mode
-If @code{transient-mark-mode} in non-@code{nil} and the region is
-active, all articles in the region will be worked upon.
-
-If there is no numeric prefix, but some articles are marked with the
-process mark, perform the operation on the articles marked with
-the process mark.
-
-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
-process marked articles onto a stack and will then clear all process
-marked articles. You can restore the previous configuration with the
-@kbd{M P y} command (@pxref{Setting Process Marks}).
-
-@vindex gnus-summary-goto-unread
-One thing that seems to shock & horrify lots of people is that, for
-instance, @kbd{3 d} does exactly the same as @kbd{d} @kbd{d} @kbd{d}.
-Since each @kbd{d} (which marks the current article as read) by default
-goes to the next unread article after marking, this means that @kbd{3 d}
-will mark the next three unread articles as read, no matter what the
-summary buffer looks like. Set @code{gnus-summary-goto-unread} to
-@code{nil} for a more straightforward action.

-@section Symbolic Prefixes
-@cindex symbolic prefixes
-
-Quite a lot of Emacs commands react to the (numeric) prefix. For
-instance, @kbd{C-u 4 C-f} moves point four charaters forward, and
-@kbd{C-u 9 0 0 I s s p} adds a permanent @code{Subject} substring score
-rule of 900 to the current article.
-
-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
-``raw'' prefix in some special way. @kbd{C-u 0 C-x C-s} means that one
-doesn't want a backup file to be created when saving the current buffer,
-for instance. But what if you want to save without making a backup
-file, and you want Emacs to flash lights and play a nice tune at the
-same time? You can't, and you're probably perfectly happy that way.
-
-@kindex M-i (Summary)
-@findex gnus-symbolic-argument
-I'm not, so I've added a second prefix---the @dfn{symbolic prefix}. The
-prefix key is @kbd{M-i} (@code{gnus-symbolic-argument}), and the next
-character typed in is the value. You can stack as many @kbd{M-i}
-prefixes as you want. @kbd{M-i a M-C-u} means ``feed the @kbd{M-C-u}
-command the symbolic prefix @code{a}''. @kbd{M-i a M-i b M-C-u} means
-``feed the @kbd{M-C-u} command the symbolic prefixes @code{a} and
-@code{b}''. You get the drift.
-
-Typing in symbolic prefixes to commands that don't accept them doesn't
-hurt, but it doesn't do any good either. Currently not many Gnus
-functions make use of the symbolic prefix.

-@node Formatting Variables
-@section Formatting Variables
-@cindex formatting variables
-
-Throughout this manual you've probably noticed lots of variables called things like @code{gnus-group-line-format} and
-@code{gnus-summary-mode-line-format}. These control how Gnus is to
-output lines in the various buffers. There's quite a lot of them.
-Fortunately, they all use the same syntax, so there's not that much to
-be annoyed by.
-
-Here's an example format spec (from the group buffer): @samp{%M%S%5y:
-%(%g%)\n}. We see that it is indeed extremely ugly, and that there are
-lots of percentages everywhere.

-* Advanced Formatting:: Modifying output in various ways.
-* User-Defined Specs:: Having Gnus call your own functions.
-* Formatting Fonts:: Making the formatting look colorful and nice.
-@end menu
-
-Currently Gnus uses the following formatting variables:
-@code{gnus-group-line-format}, @code{gnus-summary-line-format},
-@code{gnus-server-line-format}, @code{gnus-topic-line-format},
-@code{gnus-group-mode-line-format},
-@code{gnus-summary-mode-line-format},
-@code{gnus-article-mode-line-format},
-@code{gnus-server-mode-line-format}, and
-@code{gnus-summary-pick-line-format}.
-
-All these format variables can also be arbitrary elisp forms. In that
-case, they will be @code{eval}ed to insert the required lines.
-
-@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 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}.
-
-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.

-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.
-
-@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}.
-
-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" ] ")"
-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

- (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.
-
-Here's a list of all possible keys for
-@code{gnus-buffer-configuration}:
-
-@code{group}, @code{summary}, @code{article}, @code{server},
-@code{browse}, @code{message}, @code{pick}, @code{info},

-@code{reply-yank}, @code{mail-bounce}, @code{draft}, @code{pipe},
-@code{bug}, @code{compose-bounce}, and @code{score-trace}.
-
-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)

- (group 1.0)))))
-@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

-Remember all those line format specification variables?
-@code{gnus-summary-line-format}, @code{gnus-group-line-format}, and so

-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

-@node Mode Lines
-@section Mode Lines
-@cindex mode lines
-
-@vindex gnus-updated-mode-lines
-@code{gnus-updated-mode-lines} says what buffers should keep their mode
-lines updated. It is a list of symbols. Supported symbols include
-@code{group}, @code{article}, @code{summary}, @code{server},
-@code{browse}, and @code{tree}. If the corresponding symbol is present,
-Gnus will keep that mode line updated with information that may be
-pertinent. If this variable is @code{nil}, screen refresh may be
-quicker.
-
-@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:
-
-@c Hook written by Francesco Potorti` <pot@cnuce.cnr.it>
-@lisp
-(add-hook 'display-time-hook
- (lambda () (setq gnus-mode-non-string-length
- (+ 21
- (if line-number-mode 5 0)
- (if column-number-mode 4 0)
- (length display-time-string)))))
-@end lisp
-
-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
-that the default is unlikely to be desirable, as even the percentage
-complete in the buffer may be crowded off the mode line; the user should
-configure this variable appropriately for her configuration.

-@node Highlighting and Menus

-@cindex visual
-@cindex highlighting
-@cindex menus
-
-@vindex gnus-visual
-The @code{gnus-visual} variable controls most of the Gnus-prettifying
-aspects. If @code{nil}, Gnus won't attempt to create menus or use fancy
-colors or fonts. This will also inhibit loading the @file{gnus-vis.el}
-file.
-
-This variable can be a list of visual properties that are enabled. The
-following elements are valid, and are all included by default:
-
-@table @code
-@item group-highlight
-Do highlights in the group buffer.
-@item summary-highlight
-Do highlights in the summary buffer.
-@item article-highlight
-Do highlights in the article buffer.
-@item highlight
-Turn on highlighting in all buffers.
-@item group-menu
-Create menus in the group buffer.
-@item summary-menu
-Create menus in the summary buffers.
-@item article-menu
-Create menus in the article buffer.
-@item browse-menu
-Create menus in the browse buffer.
-@item server-menu
-Create menus in the server buffer.
-@item score-menu
-Create menus in the score buffers.
-@item menu
-Create menus in all buffers.
-@end table
-
-So if you only want highlighting in the article buffer and menus in all
-buffers, you could say something like:
-
-@lisp
-(setq gnus-visual '(article-highlight menu))
-@end lisp
-
-If you want highlighting only and no menus whatsoever, you'd say:
-
-@lisp
-(setq gnus-visual '(highlight))
-@end lisp
-
-If @code{gnus-visual} is @code{t}, highlighting and menus will be used
-in all Gnus buffers.
-
-Other general variables that influence the look of all buffers include:
-
-@table @code
-@item gnus-mouse-face
-@vindex gnus-mouse-face
-This is the face (i.e., font) used for mouse highlighting in Gnus. No
-mouse highlights will be done if @code{gnus-visual} is @code{nil}.
-
-@end table

-@node Daemons
-@section Daemons
-@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.)
-
-@vindex gnus-use-demon
-To set the whole thing in motion, though, you have to set
-@code{gnus-use-demon} to @code{t}.
-
-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 overdo 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
-@var{(issuer conditions ...)} 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 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.

-
-To have Gnus display Picons for you, you must be running XEmacs
-19.13 or greater since all other versions of Emacs aren't yet able to
-display images.
-
-Additionally, you must have @code{x} support compiled into XEmacs. To
-display color picons which are much nicer than the black & white one,
-you also need one of @code{xpm} or @code{gif} compiled into XEmacs.
-
-@vindex gnus-picons-convert-x-face
-If you want to display faces from @code{X-Face} headers, you should have
-the @code{xface} support compiled into XEmacs. Otherwise you must have
-the @code{netpbm} utilities installed, or munge the
-@code{gnus-picons-convert-x-face} variable to use something else.
-
-
-@node Easy Picons
-@subsubsection Easy Picons
-
-To enable displaying picons, simply put the following line in your
-@file{~/.gnus} file and start Gnus.
-
-@lisp
-(setq gnus-use-picons t)
-(add-hook 'gnus-article-display-hook 'gnus-article-display-picons t)
-(add-hook 'gnus-article-display-hook 'gnus-picons-article-display-x-face)
-@end lisp
-
-and make sure @code{gnus-picons-database} points to the directory
-containing the Picons databases.
-
-Alternatively if you want to use the web piconsearch engine add this:
-
-@lisp
-(setq gnus-picons-piconsearch-url "http://www.cs.indiana.edu:800/piconsearch")

-Gnus can display picons for you as you enter and leave groups and
-articles. It knows how to interact with three sections of the picons
-database. Namely, it can display the picons newsgroup pictures,
-author's face picture(s), and the authors domain. To enable this
-feature, you need to select where to get the picons from, and where to
-display them.
-
-@table @code
-
-@item gnus-picons-database
-@vindex gnus-picons-database
-The location of the picons database. Should point to a directory
-containing the @file{news}, @file{domains}, @file{users} (and so on)
-subdirectories. This is only useful if
-@code{gnus-picons-piconsearch-url} is @code{nil}. Defaults to
-@file{/usr/local/faces/}.
-
-@item gnus-picons-piconsearch-url
-@vindex gnus-picons-piconsearch-url
-The URL for the web picons search engine. The only currently known
-engine is @file{http://www.cs.indiana.edu:800/piconsearch}. To
-workaround network delays, icons will be fetched in the background. If
-this is @code{nil} 'the default), then picons are fetched from local
-database indicated by @code{gnus-picons-database}.
-
-@item gnus-picons-display-where
-@vindex gnus-picons-display-where
-Where the picon images should be displayed. It is @code{picons} by

-Groups that are matched by this regexp won't have their group icons
-displayed.

-Smiley maps text smiley faces---@samp{:-)}, @samp{:-=}, @samp{:-(} and

-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:

-@cindex fuzzy matching
-
-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.

-@section Thwarting Email Spam
-@cindex email 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, lustrouos 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
-twarting 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, availiable 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-existant domains is yucky, in my opinion.

-@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.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''.
-
-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.

-@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.
-
-Gnus understands all @sc{gnus} startup files.
-
-@kindex M-x gnus-bug
-@findex gnus-bug
-@cindex reporting bugs
-@cindex bugs
-Overall, a casual user who hasn't written much code that depends on
-@sc{gnus} internals should suffer no problems. If problems occur,
-please let me know by issuing that magic command @kbd{M-x gnus-bug}.

- 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

-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 immagine the labels being used for highliting, 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 summaru 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.

-Currently, I get prompted:

-The problem above is that since there is really only one subsection of

-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?

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

- Take a look at w3-menu.el in the Emacs-W3 distribution - this works out
-really well. Each menu is 'named' by a symbol that would be on a

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

-the main menubar. This approach works really well for Emacs-W3 and VM.

-
-@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.
-

-@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

-@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}.

-@node Required Backend Functions
-@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.
-
-@end table
-
-
-@node Optional Backend Functions
-@subsubsection Optional Backend Functions
-
-@table @code
-
-@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-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.

-@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.

-@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 parsable, 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:
-
-@example
-score-file = "" / "(" *element ")"
-element = rule / atom
-rule = string-rule / number-rule / date-rule
-string-rule = "(" quote string-header quote space *string-match ")"
-number-rule = "(" quote number-header quote space *number-match ")"
-date-rule = "(" quote date-header quote space *date-match ")"
-quote = <ascii 34>
-string-header = "subject" / "from" / "references" / "message-id" /
- "xref" / "body" / "head" / "all" / "followup"
-number-header = "lines" / "chars"
-date-header = "date"
-string-match = "(" quote <string> quote [ "" / [ space score [ "" /
- space date [ "" / [ space string-match-t ] ] ] ] ] ")"
-score = "nil" / <integer>
-date = "nil" / <natural number>
-string-match-t = "nil" / "s" / "substring" / "S" / "Substring" /
- "r" / "regex" / "R" / "Regex" /
- "e" / "exact" / "E" / "Exact" /
- "f" / "fuzzy" / "F" / "Fuzzy"
-number-match = "(" <integer> [ "" / [ space score [ "" /
- space date [ "" / [ space number-match-t ] ] ] ] ] ")"
-number-match-t = "nil" / "=" / "<" / ">" / ">=" / "<="
-date-match = "(" quote <string> quote [ "" / [ space score [ "" /
- space date [ "" / [ space date-match-t ] ] ] ] ")"
-date-match-t = "nil" / "at" / "before" / "after"
-atom = "(" [ required-atom / optional-atom ] ")"
-required-atom = mark / expunge / mark-and-expunge / files /
- exclude-files / read-only / touched
-optional-atom = adapt / local / eval
-mark = "mark" space nil-or-number
-nil-or-number = "nil" / <integer>
-expunge = "expunge" space nil-or-number
-mark-and-expunge = "mark-and-expunge" space nil-or-number
-files = "files" *[ space <string> ]

-read-only = "read-only" [ space "nil" / space "t" ]
-adapt = "adapt" [ space "ignore" / space "t" / space adapt-rule ]
-adapt-rule = "(" *[ <string> *[ "(" <string> <integer> ")" ] ")"
-local = "local" *[ space "(" <string> space <form> ")" ]
-eval = "eval" space <form>
-space = *[ " " / <TAB> / <NEWLINE> ]
-@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}. 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.
-
-The @code{xref} slot is really a @code{misc} slot. Any extra info will
-be put in there.
-
-
-@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

-on the lambda form. So, instead we have @code{gnus-interactive}
-function that takes a string and returns values that are usable to

-
-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.

-@node Active File Format
-@subsubsection Active File Format
-
-The active file lists all groups available on the server in
-question. It also lists the highest and lowest current article numbers
-in each group.
-
-Here's an excerpt from a typical active file:
-
-@example
-soc.motss 296030 293865 y
-alt.binaries.pictures.fractals 3922 3913 n
-comp.sources.unix 1605 1593 m
-comp.binaries.ibm.pc 5097 5089 y
-no.general 1000 900 y
-@end example
-
-Here's a pseudo-BNF definition of this file:
-
-@example
-active = *group-line
-group-line = group space high-number space low-number space flag <NEWLINE>
-group = <non-white-space string>
-space = " "
-high-number = <non-negative integer>
-low-number = <positive integer>
-flag = "y" / "n" / "m" / "j" / "x" / "=" group
-@end example
-
-For a full description of this file, see the manual pages for
-@samp{innd}, in particular @samp{active(5)}.
-
-
-@node Newsgroups File Format
-@subsubsection Newsgroups File Format
-
-The newsgroups file lists groups along with their descriptions. Not all
-groups on the server have to be listed, and not all groups in the file
-have to exist on the server. The file is meant purely as information to
-the user.
-
-The format is quite simple; a group name, a tab, and the description.
-Here's the definition:
-
-@example
-newsgroups = *line
-line = group tab description <NEWLINE>
-group = <non-white-space string>
-tab = <TAB>
-description = <string>

-Believe it or not, but some people who use Gnus haven't really used
-Emacs much before they embarked on their journey on the Gnus Love Boat.
-If you are one of those unfortunates whom ``@kbd{M-C-a}'', ``kill the
-region'', and ``set @code{gnus-flargblossen} to an alist where the key
-is a regexp that is used for matching on the group name'' are magical
-phrases with little or no meaning, then this appendix is for you. If
-you are already familiar with Emacs, just ignore this and go fondle your

-@item
-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.

-\subsec{Notes}
-{\samepage
-Gnus is complex. Currently it has some 346 interactive (user-callable)
-functions. Of these 279 are in the two major modes (Group and
-Summary/Article). Many of these functions have more than one binding, some
-have 3 or even 4 bindings. The total number of keybindings is 389. So in
-order to save 40\% space, every function is listed only once on this
-\guide, under the ``more logical'' binding. Alternative bindings are given
-in parentheses in the beginning of the description.
-
-Many Gnus commands are affected by the numeric prefix. Normally you enter a
-prefix by holding the Meta key and typing a number, but in most Gnus modes
-you don't need to use Meta since the digits are not self-inserting. The
-prefixed behavior of commands is given in [brackets]. Often the prefix is
-used to specify:
-
-\quad [distance] How many objects to move the point over.
-
-\quad [scope] How many objects to operate on (including the current one).
-
-\quad [p/p] The ``Process/Prefix Convention'': If a prefix is given then it
-determines how many objects to operate on. Else if there are some objects
-marked with the process mark \#, these are operated on. Else only the
-current object is affected.
-
-\quad [level] A group subscribedness level. Only groups with a lower or
-equal level will be affected by the operation. If no prefix is given,
-`gnus-group-default-list-level' is used. If
-`gnus-group-use-permanent-levels', then a prefix to the `g' and `l'
-commands will also set the default level.
-
-\quad [score] An article score. If no prefix is given,
-`gnus-summary-default-score' is used.
-%Some functions were not yet documented at the time of creating this
-%\guide and are clearly indicated as such.

-@node New Mail Message
-@section New Mail Message
-
-@findex message-mail
-The @code{message-mail} command pops up a new message buffer.
-
-Two optional parameters are accepted: The first will be used as the
-@code{To} header and the second as the @code{Subject} header. If these
-are @code{nil}, those two headers will be empty.
-
-
-@node New News Message
-@section New News Message
-
-@findex message-news
-The @code{message-news} command pops up a new message buffer.
-
-This function accepts two optional parameters. The first will be used
-as the @code{Newsgroups} header and the second as the @code{Subject}
-header. If these are @code{nil}, those two headers will be empty.
-
-
-@node Reply
-@section Reply
-
-@findex message-reply
-The @code{message-reply} function pops up a message buffer that's a
-reply to the message in the current buffer.
-
-@vindex message-reply-to-function
-Message uses the normal methods to determine where replies are to go
-(@pxref{Responses}), but you can change the behavior to suit your needs
-by fiddling with the @code{message-reply-to-function} variable.
-
-If you want the replies to go to the @code{Sender} instead of the
-@code{From}, you could do something like this:
-
-@lisp
-(setq message-reply-to-function
- (lambda ()
- (cond ((equal (mail-fetch-field "from") "somebody")
- (mail-fetch-field "sender"))
- (t
- nil))))
-@end lisp
-
-This function will be called narrowed to the head of the article that is
-being replied to.
-
-As you can see, this function should return a string if it has an
-opinion as to what the To header should be. If it does not, it should
-just return @code{nil}, and the normal methods for determining the To
-header will be used.
-
-This function can also return a list. In that case, each list element
-should be a cons, where the car should be the name of an header
-(eg. @code{Cc}) and the cdr should be the header value
-(eg. @samp{larsi@@ifi.uio.no}). All these headers will be inserted into
-the head of the outgoing mail.
-
-
-@node Wide Reply
-@section Wide Reply
-
-@findex message-wide-reply
-The @code{message-wide-reply} pops up a message buffer that's a wide
-reply to the message in the current buffer. A @dfn{wide reply} is a
-reply that goes out to all people listed in the @code{To}, @code{From}
-(or @code{Reply-to}) and @code{Cc} headers.
-
-@vindex message-wide-reply-to-function
-Message uses the normal methods to determine where wide replies are to go,
-but you can change the behavior to suit your needs by fiddling with the
-@code{message-wide-reply-to-function}. It is used in the same way as
-@code{message-reply-to-function} (@pxref{Reply}).
-
-@findex rmail-dont-reply-to-names
-Addresses that match the @code{rmail-dont-reply-to-names} regular
-expression will be removed from the @code{Cc} header.
-
-
-@node Followup
-@section Followup
-
-@findex message-followup
-The @code{message-followup} command pops up a message buffer that's a
-followup to the message in the current buffer.
-
-@vindex message-followup-to-function
-Message uses the normal methods to determine where followups are to go,
-but you can change the behavior to suit your needs by fiddling with the
-@code{message-followup-to-function}. It is used in the same way as
-@code{message-reply-to-function} (@pxref{Reply}).
-
-@vindex message-use-followup-to
-The @code{message-use-followup-to} variable says what to do about
-@code{Followup-To} headers. If it is @code{use}, always use the value.
-If it is @code{ask} (which is the default), ask whether to use the
-value. If it is @code{t}, use the value unless it is @samp{poster}. If
-it is @code{nil}, don't use the value.
-
-
-@node Canceling News
-@section Canceling News
-
-@findex message-cancel-news
-The @code{message-cancel-news} command cancels the article in the
-current buffer.
-
-
-@node Superseding
-@section Superseding
-
-@findex message-supersede
-The @code{message-supersede} command pops up a message buffer that will
-supersede the message in the current buffer.
-
-@vindex message-ignored-supersedes-headers
-Headers matching the @code{message-ignored-supersedes-headers} are
-removed before popping up the new message buffer. The default is@*
-@samp{^Path:\\|^Date\\|^NNTP-Posting-Host:\\|^Xref:\\|^Lines:\\|@*
-^Received:\\|^X-From-Line:\\|Return-Path:\\|^Supersedes:}.
-
-
-
-@node Forwarding
-@section Forwarding
-
-@findex message-forward

-
-@item message-signature-before-forwarded-message
-@vindex message-signature-before-forwarded-message
-If this variable is @code{t}, which it is by default, your personal
-signature will be inserted before the forwarded message. If not, the
-forwarded message will be inserted first in the new mail.
-
-@item message-included-forward-headers
-@vindex message-included-forward-headers
-Regexp matching header lines to be included in forwarded messages.
-
-@end table

-
-@node Resending
-@section Resending
-
-@findex message-resend
-The @code{message-resend} command will prompt the user for an address
-and resend the message in the current buffer to that address.
-
-@vindex message-ignored-resent-headers
-Headers that match the @code{message-ignored-resent-headers} regexp will
-be removed before sending the message. The default is
-@samp{^Return-receipt}.
-
-
-@node Bouncing
-@section Bouncing
-
-@findex message-bounce
-The @code{message-bounce} command will, if the current buffer contains a
-bounced mail message, pop up a message buffer stripped of the bounce
-information. A @dfn{bounced message} is typically a mail you've sent
-out that has been returned by some @code{mailer-daemon} as
-undeliverable.
-
-@vindex message-ignored-bounced-headers
-Headers that match the @code{message-ignored-bounced-headers} regexp

-@findex message-cite-original
-@findex sc-cite-original
-@findex message-cite-original-without-signature
-@cindex Supercite
-Function for citing an original message. The default is
-@code{message-cite-original}, which simply inserts the original message
-and prepends @samp{> } to each line.
-@code{message-cite-original-without-signature} does the same, but elides
-the signature. You can also set it to @code{sc-cite-original} to use
-Supercite.
-
-@item message-indent-citation-function
-@vindex message-indent-citation-function
-Function for modifying a citation just inserted in the mail buffer.
-This can also be a list of functions. Each function can find the
-citation between @code{(point)} and @code{(mark t)}. And each function
-should leave point and mark around the citation text as modified.
-
-@item message-signature
-@vindex message-signature
-String to be inserted at the end of the message buffer. If @code{t}
-(which is the default), the @code{message-signature-file} file will be
-inserted instead. If a function, the result from the function will be
-used instead. If a form, the result from the form will be used instead.
-If this variable is @code{nil}, no signature will be inserted at all.
-
-@item message-signature-file
-@vindex message-signature-file
-File containing the signature to be inserted at the end of the buffer.
-The default is @samp{~/.signature}.
-
-@end table
-
-Note that RFC1036bis says that a signature should be preceded by the three
-characters @samp{-- } on a line by themselves. This is to make it
-easier for the recipient to automatically recognize and process the
-signature. So don't remove those characters, even though you might feel
-that they ruin your beautiful design, like, totally.
-
-Also note that no signature should be more than four lines long.
-Including ASCII graphics is an efficient way to get everybody to believe
-that you are silly and have nothing important to say.

-The @code{message-mail-alias-type} variable controls what type of mail
-alias expansion to use. Currently only one form is supported---Message
-uses @code{mailabbrev} to handle mail aliases. If this variable is
-@code{nil}, no mail alias expansion will be performed.
-
-@code{mailabbrev} works by parsing the @file{/etc/mailrc} and
-@file{~/.mailrc} files. These files look like:
-
-@example
-alias lmi "Lars Magne Ingebrigtsen <larsi@@ifi.uio.no>"
-alias ding "ding@@ifi.uio.no (ding mailing list)"
-@end example
-
-After adding lines like this to your @file{~/.mailrc} file, you should
-be able to just write @samp{lmi} in the @code{To} or @code{Cc} (and so
-on) headers and press @kbd{SPC} to expand the alias.
-
-No expansion will be performed upon sending of the message---all
-expansions have to be done explicitly.

-@section Message Headers
-
-Message is quite aggressive on the message generation front. It has to
-be -- it's a combined news and mail agent. To be able to send combined
-messages, it has to generate all headers itself (instead of letting the
-mail/news system do it) to ensure that mail and news copies of messages
-look sufficiently similar.
-
-@table @code
-
-@item message-generate-headers-first
-@vindex message-generate-headers-first
-If non-@code{nil}, generate all headers before starting to compose the
-message.
-
-@item message-from-style
-@vindex message-from-style
-Specifies how @code{From} headers should look. There are four legal
-values:
-
-@table @code
-@item nil
-Just the address -- @samp{king@@grassland.com}.
-
-@item parens
-@samp{king@@grassland.com (Elvis Parsley)}.
-
-@item angles
-@samp{Elvis Parsley <king@@grassland.com>}.
-
-@item default
-Look like @code{angles} if that doesn't require quoting, and
-@code{parens} if it does. If even @code{parens} requires quoting, use
-@code{angles} anyway.
-
-@end table
-
-@item message-deletable-headers
-@vindex message-deletable-headers
-Headers in this list that were previously generated by Message will be
-deleted before posting. Let's say you post an article. Then you decide
-to post it again to some other group, you naughty boy, so you jump back
-to the @code{*post-buf*} buffer, edit the @code{Newsgroups} line, and
-ship it off again. By default, this variable makes sure that the old
-generated @code{Message-ID} is deleted, and a new one generated. If
-this isn't done, the entire empire would probably crumble, anarchy would
-prevail, and cats would start walking on two legs and rule the world.
-Allegedly.

-@section News Headers
-
-@vindex message-required-news-headers
-@code{message-required-news-headers} a list of header symbols. These
-headers will either be automatically generated, or, if that's
-impossible, they will be prompted for. The following symbols are legal:
-
-@table @code
-
-@item From
-@cindex From
-@findex user-full-name
-@findex user-mail-address
-This required header will be filled out with the result of the
-@code{message-make-from} function, which depends on the
-@code{message-from-style}, @code{user-full-name},
-@code{user-mail-address} variables.
-
-@item Subject
-@cindex Subject
-This required header will be prompted for if not present already.
-
-@item Newsgroups
-@cindex Newsgroups
-This required header says which newsgroups the article is to be posted
-to. If it isn't present already, it will be prompted for.
-
-@item Organization
-@cindex organization
-This optional header will be filled out depending on the
-@code{message-user-organization} variable.
-@code{message-user-organization-file} will be used if this variable is
-@code{t}. This variable can also be a string (in which case this string
-will be used), or it can be a function (which will be called with no
-parameters and should return a string to be used).
-
-@item Lines
-@cindex Lines
-This optional header will be computed by Message.
-
-@item Message-ID
-@cindex Message-ID
-@vindex mail-host-address
-@findex system-name
-@cindex Sun
-This required header will be generated by Message. A unique ID will be
-created based on the date, time, user name and system name. Message will
-use @code{mail-host-address} as the fully qualified domain name (FQDN)
-of the machine if that variable is defined. If not, it will use
-@code{system-name}, which doesn't report a FQDN on some machines --
-notably Suns.
-
-@item X-Newsreader
-@cindex X-Newsreader
-This optional header will be filled out according to the
-@code{message-newsreader} local variable.
-
-@item X-Mailer
-This optional header will be filled out according to the
-@code{message-mailer} local variable, unless there already is an
-@code{X-Newsreader} header present.
-
-@item In-Reply-To
-This optional header is filled out using the @code{Date} and @code{From}
-header of the article being replied to.
-
-@item Expires
-@cindex Expires
-This extremely optional header will be inserted according to the
-@code{message-expires} variable. It is highly deprecated and shouldn't
-be used unless you know what you're doing.
-
-@item Distribution
-@cindex Distribution
-This optional header is filled out according to the
-@code{message-distribution-function} variable. It is a deprecated and
-much misunderstood header.
-
-@item Path
-@cindex path
-This extremely optional header should probably never be used.
-However, some @emph{very} old servers require that this header is
-present. @code{message-user-path} further controls how this
-@code{Path} header is to look. If it is @code{nil}, use the server name
-as the leaf node. If it is a string, use the string. If it is neither
-a string nor @code{nil}, use the user name only. However, it is highly
-unlikely that you should need to fiddle with this variable at all.
-@end table
-
-@findex yow
-@cindex Mime-Version
-In addition, you can enter conses into this list. The car of this cons
-should be a symbol. This symbol's name is the name of the header, and
-the cdr can either be a string to be entered verbatim as the value of
-this header, or it can be a function to be called. This function should
-return a string to be inserted. For instance, if you want to insert
-@code{Mime-Version: 1.0}, you should enter @code{(Mime-Version . "1.0")}
-into the list. If you want to insert a funny quote, you could enter
-something like @code{(X-Yow . yow)} into the list. The function
-@code{yow} will then be called without any arguments.
-
-If the list contains a cons where the car of the cons is
-@code{optional}, the cdr of this cons will only be inserted if it is
-non-@code{nil}.
-
-Other variables for customizing outgoing news articles:
-
-@table @code
-
-@item message-syntax-checks
-@vindex message-syntax-checks
-If non-@code{nil}, Message will attempt to check the legality of the
-headers, as well as some other stuff, before posting. You can control
-the granularity of the check by adding or removing elements from this
-list. Legal elements are:
-
-@table @code
-@item subject-cmsg
-Check the subject for commands.
-@item sender
-@cindex Sender
-Insert a new @code{Sender} header if the @code{From} header looks odd.
-@item multiple-headers
-Check for the existence of multiple equal headers.
-@item sendsys
-@cindex sendsys
-Check for the existence of version and sendsys commands.

-Check whether the article has an @code{Approved} header, which is
-something only moderators should include.
-@item empty
-Check whether the article is empty.
-@item empty-headers

-are valid syntactically.
-@item repeated-newsgroups
-Check whether the @code{Newsgroups} and @code{Followup-to} headers
-contains repeated group names.
-@item shorten-followup-to
-Check whether to add a @code{Followup-to} header to shorten the number
-of groups to post to.
-@end table
-
-All these conditions are checked by default.
-
-@item message-ignored-news-headers
-@vindex message-ignored-news-headers

-
-@item message-signature-setup-hook
-@vindex message-signature-setup-hook
-Hook run when initializing the message buffer. It is run after the
-headers have been inserted but before the signature has been inserted.
-
-@item message-setup-hook
-@vindex message-setup-hook
-Hook run as the last thing when the message buffer has been initialized,
-but before yanked text is inserted.
-
-@item message-header-setup-hook
-@vindex message-header-setup-hook
-Hook called narrowed to the headers after initializing the headers.
-
-For instance, if you're running Gnus and wish to insert a
-@samp{Mail-Copies-To} header in all your news articles and all messages
-you send to mailing lists, you could do something like the following:
-
-@lisp
-(defun my-message-header-setup-hook ()
- (let ((group (or gnus-newsgroup-name "")))
- (when (or (message-fetch-field "newsgroups")
- (gnus-group-find-parameter group 'to-address)

- (insert "Mail-Copies-To: never\n"))))
-
-(add-hook 'message-header-setup-hook
- 'my-message-header-setup-hook)
-@end lisp
-
-@item message-send-hook
-@vindex message-send-hook
-Hook run before sending messages.
-
-If you want to add certain headers before sending, you can use the
-@code{message-add-header} function in this hook. For instance:
-@findex message-add-header
-
-@lisp
-(add-hook 'message-send-hook 'my-message-add-content)
-(defun my-message-add-content ()
- (message-add-header
- "Mime-Version: 1.0"
- "Content-Type: text/plain"
- "Content-Transfer-Encoding: 7bit"))
-@end lisp
-
-This function won't add the header if the header is already present.
-

-@vindex message-send-mail-hook
-Hook run before sending mail messages.
-
-@item message-send-news-hook

-@node Message Buffers
-@section Message Buffers
-
-Message will generate new buffers with unique buffer names when you
-request a message buffer. When you send the message, the buffer isn't
-normally killed off. Its name is changed and a certain number of old
-message buffers are kept alive.
-
-@table @code
-@item message-generate-new-buffers
-@vindex message-generate-new-buffers
-If non-@code{nil}, generate new buffers. The default is @code{t}. If
-this is a function, call that function with three parameters: The type,
-the to address and the group name. (Any of these may be @code{nil}.)
-The function should return the new buffer name.
-
-@item message-max-buffers
-@vindex message-max-buffers
-This variable says how many old message buffers to keep. If there are
-more message buffers than this, the oldest buffer will be killed. The
-default is 10. If this variable is @code{nil}, no old message buffers
-will ever be killed.
-
-@item message-send-rename-function
-@vindex message-send-rename-function
-After sending a message, the buffer is renamed from, for instance,
-@samp{*reply to Lars*} to @samp{*sent reply to Lars*}. If you don't
-like this, set this variable to a function that renames the buffer in a
-manner you like. If you don't want to rename the buffer at all, you can
-say:
-
-@lisp
-(setq message-send-rename-function 'ignore)
-@end lisp
-
-@item message-kill-buffer-on-exit
-@findex message-kill-buffer-on-exit
-If non-@code{nil}, kill the buffer immediately on exit.
-
-@end table
-
-
-@node Message Actions
-@section Message Actions
-
-When Message is being used from a news/mail reader, the reader is likely
-to want to perform some task after the message has been sent. Perhaps
-return to the previous window configuration or mark an article as
-replied.
-
-@vindex message-kill-actions
-@vindex message-postpone-actions
-@vindex message-exit-actions
-@vindex message-send-actions
-The user may exit from the message buffer in various ways. The most
-common is @kbd{C-c C-c}, which sends the message and exits. Other
-possibilities are @kbd{C-c C-s} which just sends the message, @kbd{C-c
-C-d} which postpones the message editing and buries the message buffer,
-and @kbd{C-c C-k} which kills the message buffer. Each of these actions
-have lists associated with them that contains actions to be executed:
-@code{message-send-actions}, @code{message-exit-actions},
-@code{message-postpone-actions}, and @code{message-kill-actions}.
-
-Message provides a function to interface with these lists:
-@code{message-add-action}. The first parameter is the action to be
-added, and the rest of the arguments are which lists to add this action
-to. Here's an example from Gnus:
-
-@lisp
- (message-add-action
- `(set-window-configuration ,(current-window-configuration))
- 'exit 'postpone 'kill)
-@end lisp
-
-This restores the Gnus window configuration when the message buffer is
-killed, postponed or exited.
-
-An @dfn{action} can be either: a normal function, or a list where the
-@code{car} is a function and the @code{cdr} is the list of arguments, or
-a form to be @code{eval}ed.
-
-
-@node Compatibility
-@chapter Compatibility
-@cindex compatibility
-
-Message uses virtually only its own variables---older @code{mail-}
-variables aren't consulted. To force Message to take those variables
-into account, you can put the following in your @code{.emacs} file:
-
-@lisp
-(require 'messcompat)
-@end lisp
-
-This will initialize many Message variables from the values in the
-corresponding mail variables.

-
-
-@node Responses
-@section Responses
-
-To determine where a message is to go, the following algorithm is used
-by default.
-
-@table @dfn
-@item reply
-A @dfn{reply} is when you want to respond @emph{just} to the person who
-sent the message via mail. There will only be one recipient. To
-determine who the recipient will be, the following headers are
-consulted, in turn:
-
-@table @code
-@item Reply-To
-
-@item From
-@end table
-
-
-@item wide reply
-A @dfn{wide reply} is a mail response that includes @emph{all} entities
-mentioned in the message you are responded to. All mailboxes from the
-following headers will be concatenated to form the outgoing
-@code{To}/@code{Cc} headers:
-
-@table @code
-@item From
-(unless there's a @code{Reply-To}, in which case that is used instead).
-
-@item Cc
-
-@item To
-@end table
-
-If a @code{Mail-Copies-To} header is present, it will also be included
-in the list of mailboxes. If this header is @samp{never}, that means
-that the @code{From} (or @code{Reply-To}) mailbox will be suppressed.
-
-
-@item followup
-A @dfn{followup} is a response sent via news. The following headers
-(listed in order of precedence) determine where the response is to be
-sent:
-
-@table @code
-
-@item Followup-To
-
-@item Newsgroups
-
-@end table
-
-If a @code{Mail-Copies-To} header is present, it will be used as the
-basis of the new @code{Cc} header, except if this header is
-@samp{never}.

-@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.
-@end table
-
-@node User Interface, Programming Example, Introduction, Top
-@comment node-name, next, previous, up
-@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
-Face used for buttons when the mouse pointer is above it.
-@end defopt
-
-@subsection Navigation
-
-You can use all the normal Emacs commands to move around in a form
-buffer, plus you will have these additional commands:
-
-@table @kbd
-@item @key{TAB}
-@deffn Command widget-forward &optional count
-Move point @var{count} buttons or editing fields forward.
-@end deffn
-@item @key{M-TAB}
-@deffn Command widget-backward &optional count
-Move point @var{count} buttons or editing fields backward.

-@section Setting Up the Buffer
-
-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.
-
-@defvr Const widget-keymap
-A keymap with the global keymap as its parent.@*
-@key{TAB} and @kbd{C-@key{TAB}} are bound to @code{widget-forward} and
-@code{widget-backward}, respectively. @kbd{@key{RET}} and @kbd{mouse-2}
-are bound to @code{widget-button-press} and
-@code{widget-button-}.@refill
-@end defvr
-
-@defvar widget-global-map
-Keymap used by @code{widget-button-press} and @code{widget-button-click}
-when not on a button. By default this is @code{global-map}.
-@end defvar

-@section Basic Types
-
-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 :tag-glyph
-Name of image to use instead of the string specified by `:tag' on
-Emacsen that supports it.
-
-@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.
-

-Widgets with tabbing order @code{-1} are ignored.
-
-@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
-This keyword is only used for members of a @code{radio-button-choice} or
-@code{checklist}. The value should be a list of extra keyword
-arguments, which will be used when creating the @code{radio-button} or
-@code{checkbox} associated with this item.
-
-@end table
-
-@deffn {User Option} widget-glyph-directory
-Directory where glyphs are found.
-Widget will look here for a file with the same name as specified for the
-image, with either a @samp{.xpm} (if supported) or @samp{.xbm} extension.

-
-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.

-
-A number of widgets for editing s-expressions (lisp types) are also
-available. These basically fall in three categories: @dfn{atoms},
-@dfn{composite types}, and @dfn{generic}.
-
-@menu
-* generic::
-* atoms::
-* composite::
-@end menu
-
-@node generic, atoms, Sexp Types, Sexp Types
-@comment node-name, next, previous, up
-@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
