-Otherwise you need a local copy of his database. For instructions on

-@uref{http://www.cs.indiana.edu/picons/ftp/index.html}. Gnus expects

+@vindex gnus-picon-databases
+For instructions on obtaining and installing the picons databases,

If you are using Debian GNU/Linux, saying @samp{apt-get install

+Picons databases.
-@node Picon Requirements
-@subsubsection Picon Requirements
-
-To have Gnus display Picons for you, you must have @code{x} support
-compiled into XEmacs. To display color picons which are much nicer
-than the black & white one, you also need one of @code{xpm} or
-@code{gif} compiled into XEmacs.
-
-@vindex gnus-picons-convert-x-face
-If you want to display faces from @code{X-Face} headers, you should have
-the @code{xface} support compiled into XEmacs. Otherwise you must have
-the @code{netpbm} utilities installed, or munge the
-@code{gnus-picons-convert-x-face} variable to use something else.
-(NOTE: @code{x-face} is used in the variable name, not @code{xface})
-
-@node Easy Picons
-@subsubsection Easy Picons
-
-To enable displaying picons, simply put the following line in your
-@file{~/.gnus} file and start Gnus.
-
-@lisp
-(setq gnus-use-picons t)
-(setq gnus-treat-display-picons t)
-@end lisp
-
-and make sure @code{gnus-picons-database} points to the directory
-containing the Picons databases.
-
-Alternatively if you want to use the web piconsearch engine add this:
-
-@lisp
-(setq gnus-picons-piconsearch-url
- "http://www.cs.indiana.edu:800/piconsearch")

-Gnus can display picons for you as you enter and leave groups and
-articles. It knows how to interact with three sections of the picons
-database. Namely, it can display the picons newsgroup pictures,
-author's face picture(s), and the authors domain. To enable this
-feature, you need to select where to get the picons from, and where to
-display them.
+The following variables offer control over where things are located.
@table @code
-@item gnus-picons-database
-@vindex gnus-picons-database
-The location of the picons database. Should point to a directory
+@item gnus-picon-databases
+@vindex gnus-picon-databases
+The location of the picons database. This is a list of directories
containing the @file{news}, @file{domains}, @file{users} (and so on)
-subdirectories. This is only useful if
-@code{gnus-picons-piconsearch-url} is @code{nil}. Defaults to
-@file{/usr/local/faces/}.
-
-@item gnus-picons-piconsearch-url
-@vindex gnus-picons-piconsearch-url
-The URL for the web picons search engine. The only currently known
-engine is @uref{http://www.cs.indiana.edu:800/piconsearch}. To
-workaround network delays, icons will be fetched in the background. If
-this is @code{nil} 'the default), then picons are fetched from local
-database indicated by @code{gnus-picons-database}.
-
-@item gnus-picons-display-where
-@vindex gnus-picons-display-where
-Where the picon images should be displayed. It is @code{picons} by
-default (which by default maps to the buffer @samp{*Picons*}). Other
-valid places could be @code{article}, @code{summary}, or
-@samp{*scratch*} for all I care. Just make sure that you've made the
-buffer visible using the standard Gnus window configuration
-routines---@pxref{Window Layout}.
-
-@item gnus-picons-group-excluded-groups
-@vindex gnus-picons-group-excluded-groups
-Groups that are matched by this regexp won't have their group icons
-displayed.
+subdirectories. Defaults to @code{("/usr/lib/picon"
+"/usr/local/faces")}.
-@end table
-
-Note: If you set @code{gnus-use-picons} to @code{t}, it will set up your
-window configuration for you to include the @code{picons} buffer.
-
-Now that you've made those decision, you need to add the following
-functions to the appropriate hooks so these pictures will get displayed
-at the right time.
-
-@vindex gnus-picons-display-where
-@table @code
-@item gnus-article-display-picons
-@findex gnus-article-display-picons
-Looks up and displays the picons for the author and the author's domain
-in the @code{gnus-picons-display-where} buffer.
-
-@item gnus-picons-article-display-x-face
-@findex gnus-picons-article-display-x-face
-Decodes and displays the X-Face header if present.
-(NOTE: @code{x-face} is used in the function name, not @code{xface})

want to add @samp{"unknown"} to this list.
-@item gnus-picons-convert-x-face
-@vindex gnus-picons-convert-x-face
-If you don't have @code{xface} support builtin XEmacs, this is the
-command to use to convert the @code{X-Face} header to an X bitmap
-(@code{xbm}). Defaults to @code{(format "@{ echo '/* Width=48,
-Height=48 */'; uncompface; @} | icontopbm | pbmtoxbm > %s"
-gnus-picons-x-face-file-name)}
-(NOTE: @code{x-face} is used in the variable name, not @code{xface})

-Names a temporary file to store the @code{X-Face} bitmap in. Defaults
-to @code{(format "/tmp/picon-xface.%s.xbm" (user-login-name))}.
-(NOTE: @code{x-face} is used in the variable name, not @code{xface})
-
-@item gnus-picons-has-modeline-p
-@vindex gnus-picons-has-modeline-p
-If you have set @code{gnus-picons-display-where} to @code{picons}, your
-XEmacs frame will become really cluttered. To alleviate this a bit you
-can set @code{gnus-picons-has-modeline-p} to @code{nil}; this will
-remove the mode line from the Picons buffer. This is only useful if
-@code{gnus-picons-display-where} is @code{picons}.
-
-@item gnus-picons-refresh-before-display
-@vindex gnus-picons-refresh-before-display
-If non-nil, display the article buffer before computing the picons.
-Defaults to @code{nil}.

-@item gnus-picons-display-as-address
-@vindex gnus-picons-display-as-address
-If @code{t} display textual email addresses along with pictures.

-
-@item gnus-picons-setup-hook
-@vindex gnus-picons-setup-hook
-Hook run in the picon buffer, if that is displayed.
-
-@item gnus-picons-display-article-move-p
-@vindex 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 @code{nil}, display the picons in the @code{From} and
-@code{Newsgroups} lines. This is the default.
-
-@item gnus-picons-clear-cache-on-shutdown
-@vindex 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 @code{nil},
-Gnus will never clear the cache itself; you will have to manually call
-@code{gnus-picons-clear-cache} to clear it. Otherwise the cache will be
-cleared every time you exit Gnus. Defaults to @code{t}.
