-   You can embed smilies into pages, if you load this plugin. Only the
-   location and URL to the images must be configured, the directory is
-   read in at initialization.
-   Images with a textual name then can be referenced as   :word:
-   from within any WikiPage, and ordinary smilies can be written as is
-   and get replaced by their graphical counterpart (if there is one).
-
-   A prepared "_smilies.tar.gz" package is available from
-   http://erfurtwiki.sourceforge.net/downloads/contrib-add-ons/
-   Just untar it in the ewiki main directory, due to the 'special'
-   characters this however only works on Unix filesystems.
