@vindex gnus-save-newsrc-file
+@vindex gnus-read-newsrc-file
You can turn off writing the @file{.newsrc} file by setting
@code{gnus-save-newsrc-file} to @code{nil}, which means you can delete
the file and save some space, as well as exiting from Gnus faster.
However, this will make it impossible to use other newsreaders than

+Gnus. But hey, who would want to, right? Similarly, setting
+@code{gnus-read-newsrc-file} to @code{nil} makes Gnus ignore the
+@file{.newsrc} file and any @file{.newsrc-SERVER} files, which is
+convenient if you have a tendency to use Netscape once in a while.
@vindex gnus-save-killed-list
If @code{gnus-save-killed-list} (default @code{t}) is @code{nil}, Gnus
at all. In any case, @code{some} should be faster than @code{nil}, and
is certainly faster than @code{t} over slow lines.
+Some news servers (Leafnode and old versions of INN, for instance) do
+not support the @code{LIST ACTIVE group}. For these servers, @code{nil}
+is probably the most efficient value for this variable.
+
If this variable is @code{nil}, Gnus will ask for group info in total
lock-step, which isn't very fast. If it is @code{some} and you use an
@sc{nntp} server, Gnus will pump out commands as fast as it can, and
performance, but if the server does not support the aforementioned
@code{LIST ACTIVE group} command, this isn't very nice to the server.
+If you think that starting up Gnus takes too long, try all the three
+different values for this variable and see what works best for you.
+
In any case, if you use @code{some} or @code{nil}, you should definitely
kill all groups that you aren't interested in to speed things up.

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

+@subsection Mail in a Newsreader
+
+If you are used to traditional mail readers, but have decided to switch
+to reading mail with Gnus, you may find yourself experiencing something
+of a culture shock.
+
+Gnus does not behave like traditional mail readers. If you want to make
+it behave that way, you can, but it's an uphill battle.
+
+Gnus, by default, handles all its groups using the same approach. This
+approach is very newsreaderly---you enter a group, see the new/unread
+messages, and when you read the messages, they get marked as read, and
+you don't see them any more. (Unless you explicitly ask for them.)
+
+In particular, you do not do anything explicitly to delete messages.
+
+Does this mean that all the messages that have been marked as read are
+deleted? How awful!
+
+But, no, it means that old messages are @dfn{expired} according to some
+scheme or other. For news messages, the expire process is controlled by
+the news administrator; for mail, the expire process is controlled by
+you. The expire process for mail is covered in depth in @pxref{Expiring
+Mail}.
+
+What many Gnus users find, after using it a while for both news and
+mail, is that the transport mechanism has very little to do with how
+they want to treat a message.
+
+Many people subscribe to several mailing lists. These are transported
+via SMTP, and are therefore mail. But we might go for weeks without
+answering, or even reading these messages very carefully. We may not
+need to save them because if we should need to read one again, they are
+archived somewhere else.
+
+Some people have local news groups which have only a handful of readers.
+These are transported via NNTP, and are therefore news. But we may need
+to read and answer a large fraction of the messages very carefully in
+order to do our work. And there may not be an archive, so we may need
+to save the interesting messages the same way we would personal mail.
+
+The important distinction turns out to be not the transport mechanism,
+but other factors such as how interested we are in the subject matter,
+or how easy it is to retrieve the message if we need to read it again.
+
+Gnus provides many options for sorting mail into ``groups'' which behave
+like newsgroups, and for treating each group (whether mail or news)
+differently.
+
+Some users never get comfortable using the Gnus (ahem) paradigm and wish
+that Gnus should grow up and be a male, er, mail reader. It is possible
+to whip Gnus into a more mailreaderly being, but, as said before, it's
+not easy. People who prefer proper mail readers should try @sc{vm}
+instead, which is an excellent, and proper, mail reader.
+
+I don't mean to scare anybody off, but I want to make it clear that you
+may be required to learn a new way of thinking about messages. After
+you've been subjected to The Gnus Way, you will come to love it. I can
+guarantee it. (At least the guy who sold me the Emacs Subliminal
+Brain-Washing Functions that I've put into Gnus did guarantee it. You
+Will Be Assimilated. You Love Gnus. You Love The Gnus Mail Way.
+You Do.)

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

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

* Conformity:: Gnus tries to conform to all standards.
* Emacsen:: Gnus can be run on a few modern Emacsen.

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

+I'm having trouble accessing a newsgroup with a "+" in its name with

+"nntp+msnews.microsoft.com:microsoft.public.multimedia.directx.html+time"
