that you have on your native groups. Use with caution.
+@kindex M-x gnus-group-clear-data
+@findex gnus-group-clear-data
+Clear the data from the current group only---nix out marks and the
+list of read articles (@code{gnus-group-clear-data}).
+
After changing servers, you @strong{must} move the cache hierarchy away,
since the cached articles will have wrong article numbers, which will
affect which articles Gnus thinks are read.
+@code{gnus-group-clear-data-on-native-groups} will ask you if you want
+to have it done automatically; for @code{gnus-group-clear-data}, you
+can use @kbd{M-x gnus-cache-move-cache} (but beware, it will move the
+cache for all groups).

-If this variable is a string, this string will be executed in a

-face as the argument. If the @code{gnus-article-x-face-too-ugly} (which
-is a regexp) matches the @code{From} header, the face will not be shown.

-the @code{uncompface} and @code{icontopbm} programs look for a package
-like `compface' or `faces-xface' on a GNU/Linux system.} to view the
-face. Under XEmacs or Emacs 21+ with suitable image support, the
-default action is to display the face before the @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 external programs
-from the @code{pbmplus} package and friends.@footnote{On a GNU/Linux
-system look for packages with names like @code{netpbm} or

+@code{X-Face} headers describe a 48x48 pixel black-and-white (1 bit

+
+Decoding an @code{X-Face} header either requires an Emacs that has
+@samp{compface} support (which most XEmacs versions has), or that you
+have @samp{compface} installed on your system. If either is true,
+Gnus will default to displaying @code{X-Face} headers.
+
+The variable that controls this is the
+@code{gnus-article-x-face-command} variable. If this variable is a
+string, this string will be executed in a sub-shell. If it is a
+function, this function will be called with the face as the argument.
+If the @code{gnus-article-x-face-too-ugly} (which is a regexp) matches
+the @code{From} header, the face will not be shown.
+
+The default action under Emacs 20 is to fork off the @code{display}
+program@footnote{@code{display} is from the ImageMagick package. For
+the @code{uncompface} and @code{icontopbm} programs look for a package
+like @code{compface} or @code{faces-xface} on a GNU/Linux system.} to
+view the face.
+
+Under XEmacs or Emacs 21+ with suitable image support, the default
+action is to display the face before the @code{From} header. (It's
+nicer if XEmacs has been compiled with @code{X-Face} support---that
+will make display somewhat faster. If there's no native @code{X-Face}
+support, Gnus will try to convert the @code{X-Face} header using
+external programs from the @code{pbmplus} package and
+friends.@footnote{On a GNU/Linux system look for packages with names
+like @code{netpbm}, @code{libgr-progs} and @code{compface}.})
+
+(NOTE: @code{x-face} is used in the variable/function names, not
+@code{xface}).
+
+Gnus provides a few convenience functions and variables to allow
+easier insertion of X-Face headers in outgoing messages.
+
+@findex gnus-random-x-face
+@code{gnus-random-x-face} goes through all the @samp{pbm} files
+in @code{gnus-x-face-directory} and picks one at random, and then
+converts it to the X-Face format by using the
+@code{gnus-convert-pbm-to-x-face-command} shell command. The
+@samp{pbm} files should be 48x48 pixels big.
+
+@code{gnus-x-face-from-file} takes a file as the parameter, and then
+converts the file to X-Face format by using the
+@code{gnus-convert-image-to-x-face-command} shell command.
+
+Here's how you would typically use the former function. Put something
+like the folllowing in your @file{.gnus.el} file:
+
+@lisp
+(setq message-required-news-headers
+ (nconc message-required-news-headers
+ (list '(X-Face . gnus-random-x-face))))
+@end lisp
+
+Using the latter function would be something like this:
+
+@lisp
+(setq message-required-news-headers
+ (nconc message-required-news-headers
+ (list '(X-Face . (lambda ()
+ (gnus-x-face-from-file

Gnus is now a MIME-capable reader. This affects many parts of
Gnus, and adds a slew of new commands. See the manual for details.
If this is non-@code{nil}, all threads in the summary buffer will be
hidden initially.
+This can also be a predicate specifier (@pxref{Predicate Specifiers}).
+Avaliable predicates are @code{gnus-article-unread-p} and
+@code{gnus-article-unseen-p}.
+
+Here's an example:
+
+@lisp
+(setq gnus-thread-hide-subtree
+ '(or gnus-article-unread-p
+ gnus-article-unseen-p))
+@end lisp
+
+(It's a pretty nonsensical example, since all unseen articles are also
+unread, but you get my drift.)
+

@item gnus-updated-mode-lines
If this is @code{nil}, Gnus will not put information in the buffer mode
lines, which might save some time.
