Picon Useless Configuration
...........................

   The following variables offer further control over how things are
done, where things are located, and other useless stuff you really
don't need to worry about.

`gnus-picons-news-directories'
     List of subdirectories to search in `gnus-picons-database' for
     newsgroups faces.  `("news")' is the default.

`gnus-picons-user-directories'
     List of subdirectories to search in `gnus-picons-database' for user
     faces.  `("local" "users" "usenix" "misc")' is the default.

`gnus-picons-domain-directories'
     List of subdirectories to search in `gnus-picons-database' for
     domain name faces.  Defaults to `("domains")'.  Some people may
     want to add `"unknown"' to this list.

`gnus-picons-convert-x-face'
     If you don't have `xface' support builtin XEmacs, this is the
     command to use to convert the `X-Face' header to an X bitmap
     (`xbm').  Defaults to `(format "{ echo '/* Width=48, Height=48
     */'; uncompface; } | icontopbm | pbmtoxbm > %s"
     gnus-picons-x-face-file-name)'

`gnus-picons-x-face-file-name'
     Names a temporary file to store the `X-Face' bitmap in.  Defaults
     to `(format "/tmp/picon-xface.%s.xbm" (user-login-name))'.

`gnus-picons-has-modeline-p'
     If you have set `gnus-picons-display-where' to `picons', your
     XEmacs frame will become really cluttered.  To alleviate this a
     bit you can set `gnus-picons-has-modeline-p' to `nil'; this will
     remove the mode line from the Picons buffer.  This is only useful
     if `gnus-picons-display-where' is `picons'.

`gnus-picons-refresh-before-display'
     If non-nil, display the article buffer before computing the picons.
     Defaults to `nil'.

`gnus-picons-display-as-address'
     If `t' display textual email addresses along with pictures.
     Defaults to `t'.

`gnus-picons-file-suffixes'
     Ordered list of suffixes on picon file names to try.  Defaults to
     `("xpm" "gif" "xbm")' minus those not builtin your XEmacs.

`gnus-picons-setup-hook'
     Hook run in the picon buffer, if that is displayed.

`gnus-picons-display-article-move-p'
     Whether to move point to first empty line when displaying picons.
     This has only an effect if `gnus-picons-display-where' has value
     `article'.

     If `nil', display the picons in the `From' and `Newsgroups' lines.
     This is the default.

`gnus-picons-clear-cache-on-shutdown'
     Whether to clear the picons cache when exiting gnus.  Gnus caches
     every picons it finds while it is running.  This saves some time
     in the search process but eats some memory.  If this variable is
     set to `nil', Gnus will never clear the cache itself; you will
     have to manually call `gnus-picons-clear-cache' to clear it.
     Otherwise the cache will be cleared every time you exit Gnus.
     Defaults to `t'.
