Resurrect GNUS-NEWS autogeneration

* doc/misc/gnus-coding.texi (Gnus Maintenance Guide): Update
GNUS-NEWS section to match current file locations and procedure.
* etc/GNUS-NEWS: Regenerate by using new procedure.
* lisp/Makefile.in (update-gnus-news): New rule, containing a
procedure for building GNUS-NEWS.  The old procedure got lost
somehow when Gnus was merged into Emacs.

-* New features
+* Supported Emacs versions The following Emacs versions are supported by No
+Gnus:
 
-** nnimap can request and use the Gmail "X-GM-LABELS".
+** Emacs 22 and up
+** XEmacs 21.4
+** XEmacs 21.5
+** SXEmacs
 
-** New package `gnus-notifications.el' can send notifications when you
-   receive new messages.
+
+* Installation changes
+
+** Upgrading from previous (stable) version if you have used No Gnus.
+
+If you have tried No Gnus (the unstable Gnus branch leading to this
+release) but went back to a stable version, be careful when upgrading to
+this version.  In particular, you will probably want to remove the
+'~/News/marks' directory (perhaps selectively), so that flags are read
+from your '~/.newsrc.eld' instead of from the stale marks file, where
+this release will store flags for nntp.  See a later entry for more
+information about nntp marks.  Note that downgrading isn't safe in
+general.
+
+** Incompatibility when switching from Emacs 23 to Emacs 22 In Emacs 23,
+Gnus uses Emacs's new internal coding system 'utf-8-emacs' for saving
+articles drafts and '~/.newsrc.eld'.  These files may not be read
+correctly in Emacs 22 and below.  If you want to use Gnus across
+different Emacs versions, you may set 'mm-auto-save-coding-system' to
+'emacs-mule'.
+
+** Lisp files are now installed in '.../site-lisp/gnus/' by default.  It
+defaulted to '.../site-lisp/' formerly.  In addition to this, the new
+installer issues a warning if other Gnus installations which will shadow
+the latest one are detected.  You can then remove those shadows manually
+or remove them using 'make remove-installed-shadows'.
+
+** The installation directory name is allowed to have spaces and/or tabs.
+
+
+* New packages and libraries within Gnus
+
+** New version of 'nnimap'
+
+'nnimap' has been reimplemented in a mostly-compatible way.  See the Gnus
+manual for a description of the new interface.  In particular,
+'nnimap-inbox' and the client side split method has changed.
+
+** Gnus includes the Emacs Lisp SASL library.
+
+This provides a clean API to SASL mechanisms from within Emacs.  The user
+visible aspects of this, compared to the earlier situation, include
+support for DIGEST-MD5 and NTLM.  *Note Emacs SASL: (sasl)Top.
+
+** ManageSieve connections uses the SASL library by default.
+
+The primary change this brings is support for DIGEST-MD5 and NTLM, when
+the server supports it.
+
+** Gnus includes a password cache mechanism in password.el.
+
+It is enabled by default (see 'password-cache'), with a short timeout of
+16 seconds (see 'password-cache-expiry').  If PGG is used as the PGP back
+end, the PGP passphrase is managed by this mechanism.  Passwords for
+ManageSieve connections are managed by this mechanism, after querying the
+user about whether to do so.
+
+** Using EasyPG with Gnus When EasyPG, is available, Gnus will use it
+instead of PGG.  EasyPG is an Emacs user interface to GNU Privacy Guard.
+ *Note EasyPG Assistant user's manual: (epa)Top.  EasyPG is included in
+Emacs 23 and available separately as well.
+
+
+* Changes in group mode
+
+** Symbols like 'gcc-self' now have the same precedence rules in
+'gnus-parameters' as other "real" variables: The last match wins instead
+of the first match.
+
+** Old intermediate incoming mail files ('Incoming*') are deleted after a
+couple of days, not immediately.  *Note Mail Source Customization::.
+(New in Gnus 5.10.10 / No Gnus 0.8)
+
+
+* Changes in summary and article mode
+
+** There's now only one variable that determines how HTML is rendered:
+'mm-text-html-renderer'.
+
+** Gnus now supports sticky article buffers.  Those are article buffers that
+are not reused when you select another article.  *Note Sticky Articles::.
+
+** Gnus can selectively display 'text/html' articles with a WWW browser with
+'K H'.  *Note MIME Commands::.
+
+** International host names (IDNA) can now be decoded inside article bodies
+using 'W i' ('gnus-summary-idna-message').  This requires that GNU Libidn
+(<http://www.gnu.org/software/libidn/>) has been installed.
+
+** The non-ASCII group names handling has been much improved.  The back ends
+that fully support non-ASCII group names are now 'nntp', 'nnml', and
+'nnrss'.  Also the agent, the cache, and the marks features work with
+those back ends.  *Note Non-ASCII Group Names::.
+
+** Gnus now displays DNS master files sent as text/dns using dns-mode.
+
+** Gnus supports new limiting commands in the Summary buffer: '/ r'
+('gnus-summary-limit-to-replied') and '/ R'
+('gnus-summary-limit-to-recipient').  *Note Limiting::.
+
+** You can now fetch all ticked articles from the server using 'Y t'
+('gnus-summary-insert-ticked-articles').  *Note Summary Generation
+Commands::.
+
+** Gnus supports a new sort command in the Summary buffer: 'C-c C-s C-t'
+('gnus-summary-sort-by-recipient').  *Note Summary Sorting::.
+
+** S/MIME now features LDAP user certificate searches.  You need to
+configure the server in 'smime-ldap-host-list'.
+
+** URLs inside OpenPGP headers are retrieved and imported to your PGP key
+ring when you click on them.
+
+** Picons can be displayed right from the textual address, see
+'gnus-picon-style'.  *Note Picons::.
+
+** ANSI SGR control sequences can be transformed using 'W A'.
+
+ANSI sequences are used in some Chinese hierarchies for highlighting
+articles ('gnus-article-treat-ansi-sequences').
 
-** If you have the "tnef" program installed, Gnus will display ms-tnef
-   files, aka "winmail.dat".
+** Gnus now MIME decodes articles even when they lack "MIME-Version" header.
+This changes the default of 'gnus-article-loose-mime'.
 
-** Archives (like tar and zip files) will be automatically unpacked,
-   and the files inside the packages will be displayed as MIME parts.
+** 'gnus-decay-scores' can be a regexp matching score files.  For example,
+set it to '\\.ADAPT\\'' and only adaptive score files will be decayed.
+ *Note Score Decays::.
 
-** shr has a new command `z' that cycles through image sizes.
+** Strings prefixing to the 'To' and 'Newsgroup' headers in summary lines
+when using 'gnus-ignored-from-addresses' can be customized with
+'gnus-summary-to-prefix' and 'gnus-summary-newsgroup-prefix'.  *Note To
+From Newsgroups::.
 
-** `backtab' in the summary buffer now selects the previous link in
-   the article buffer.
+** You can replace MIME parts with external bodies.  See
+'gnus-mime-replace-part' and 'gnus-article-replace-part'.  *Note MIME
+Commands::, *note Using MIME::.
 
-** Using the "X-Message-SMTP-Method" header in Message buffers now
-   allows specifying how messages are to be sent.  For example:
+** The option 'mm-fill-flowed' can be used to disable treatment of
+format=flowed messages.  Also, flowed text is disabled when sending
+inline PGP signed messages.  *Note Flowed text: (emacs-mime)Flowed text.
+(New in Gnus 5.10.7)
 
-   X-Message-SMTP-Method: smtp smtp.fsf.org 587
+** Now the new command 'S W' ('gnus-article-wide-reply-with-original') for a
+wide reply in the article buffer yanks a text that is in the active
+region, if it is set, as well as the 'R'
+('gnus-article-reply-with-original') command.  Note that the 'R' command
+in the article buffer no longer accepts a prefix argument, which was used
+to make it do a wide reply.  *Note Article Keymap::.
 
-** Gnus keeps track of non-existent articles for nnimap groups, so
-   that sparse IMAP folders now list a correct number of messages in
-   them.
+** The new command 'C-h b' ('gnus-article-describe-bindings') used in the
+article buffer now shows not only the article commands but also the real
+summary commands that are accessible from the article buffer.
 
-** Gnus will guess the real type of MIME parts of type
-   application/octet-stream based on the file suffix.  So an
-   application/octet-stream with a name of "rms.jpg" will be displayed
-   as an image/jpeg type by default, for instance.
+
+* Changes in Message mode
+
+** Gnus now defaults to saving all outgoing messages in per-month nnfolder
+archives.
+
+** Gnus now supports the "hashcash" client puzzle anti-spam mechanism.  Use
+'(setq message-generate-hashcash t)' to enable.  *Note Hashcash::.
+
+** You can now drag and drop attachments to the Message buffer.  See
+'mml-dnd-protocol-alist' and 'mml-dnd-attach-options'.  *Note MIME:
+(message)MIME.
+
+** The option 'message-yank-empty-prefix' now controls how empty lines are
+prefixed in cited text.  *Note Insertion Variables: (message)Insertion
+Variables.
+
+** Gnus uses narrowing to hide headers in Message buffers.  The 'References'
+header is hidden by default.  To make all headers visible, use '(setq
+message-hidden-headers nil)'.  *Note Message Headers: (message)Message
+Headers.
+
+** You can highlight different levels of citations like in the article
+buffer.  See 'gnus-message-highlight-citation'.
+
+** 'auto-fill-mode' is enabled by default in Message mode.  See
+'message-fill-column'.  *Note Message Headers: (message)Various Message
+Variables.
+
+** You can now store signature files in a special directory named
+'message-signature-directory'.
+
+** The option 'message-citation-line-format' controls the format of the
+"Whomever writes:" line.  You need to set
+'message-citation-line-function' to
+'message-insert-formatted-citation-line' as well.
+
+
+* Changes in Browse Server mode
+
+** Gnus' sophisticated subscription methods are now available in Browse
+Server buffers as well using the variable
+'gnus-browse-subscribe-newsgroup-method'.
+
+
+* Changes in back ends
+
+** The nntp back end stores article marks in '~/News/marks'.
+
+The directory can be changed using the (customizable) variable
+'nntp-marks-directory', and marks can be disabled using the (back end)
+variable 'nntp-marks-is-evil'.  The advantage of this is that you can
+copy '~/News/marks' (using rsync, scp or whatever) to another Gnus
+installation, and it will realize what articles you have read and marked.
+The data in '~/News/marks' has priority over the same data in
+'~/.newsrc.eld'.
+
+** You can import and export your RSS subscriptions from OPML files.  *Note
+RSS::.
+
+** IMAP identity (RFC 2971) is supported.
 
-** `nnimap-inbox' can now be a list of mail box names.
-   
+By default, Gnus does not send any information about itself, but you can
+customize it using the variable 'nnimap-id'.
+
+** The 'nnrss' back end now supports multilingual text.  Non-ASCII group
+names for the 'nnrss' groups are also supported.  *Note RSS::.
+
+** Retrieving mail with POP3 is supported over SSL/TLS and with StartTLS.
+
+** The nnml back end allows other compression programs beside 'gzip' for
+compressed message files.  *Note Mail Spool::.
+
+** The nnml back end supports group compaction.
+
+This feature, accessible via the functions 'gnus-group-compact-group' ('G
+z' in the group buffer) and 'gnus-server-compact-server' ('z' in the
+server buffer) renumbers all articles in a group, starting from 1 and
+removing gaps.  As a consequence, you get a correct total article count
+(until messages are deleted again).
+
+
+* Appearance
+
+** The tool bar has been updated to use GNOME icons.  You can also customize
+the tool bars: 'M-x customize-apropos RET -tool-bar$' should get you
+started.  (Only for Emacs, not in XEmacs.)
+
+** The tool bar icons are now (de)activated correctly in the group buffer,
+see the variable 'gnus-group-update-tool-bar'.  Its default value depends
+on your Emacs version.
+
+** You can change the location of XEmacs's toolbars in Gnus buffers.  See
+'gnus-use-toolbar' and 'message-use-toolbar'.
+
+
+* Miscellaneous changes
+
+** Having edited the select-method for the foreign server in the server
+buffer is immediately reflected to the subscription of the groups which
+use the server in question.  For instance, if you change
+'nntp-via-address' into 'bar.example.com' from 'foo.example.com', Gnus
+will connect to the news host by way of the intermediate host
+'bar.example.com' from next time.
+
+** The 'all.SCORE' file can be edited from the group buffer using 'W e'.
+
+** You can set 'gnus-mark-copied-or-moved-articles-as-expirable' to a
+non-'nil' value so that articles that have been read may be marked as
+expirable automatically when copying or moving them to a group that has
+auto-expire turned on.  The default is 'nil' and copying and moving of
+articles behave as before; i.e., the expirable marks will be unchanged
+except that the marks will be removed when copying or moving articles to
+a group that has not turned auto-expire on.  *Note Expiring Mail::.
+
+** NoCeM support has been removed.
+
+** Carpal mode has been removed.
