Picon 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-database'
     The location of the picons database.  Should point to a directory
     containing the `news', `domains', `users' (and so on)
     subdirectories.  Defaults to `/usr/local/faces'.

`gnus-picons-news-directory'
     Sub-directory of the faces database containing the icons for
     newsgroups.

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

`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'
     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-buffer'
     The name of the buffer that `picons' points to.  Defaults to
     `*Icon Buffer*'.
