 =head1 DESCRIPTION
 
 L<storytags> is a blosxom plugin to format a per-story $storytags::taglist 
-string. The string is a comma-separated list of the tags defined for the
-story, prefixed by $storytags::prefix, and suffixed by $storytags::suffix.
-If no tags are defined, then $taglist will be the empty string '' (i.e. no
-prefix and suffix are added).
+string, and a @storytags::taglist array of tags. The $taglist is a 
+comma-separated list of the tags defined for the story, prefixed by 
+$storytags::prefix, and suffixed by $storytags::suffix. If no tags are 
+defined, then $taglist will be the empty string '' (i.e. no prefix and 
+suffix are added). @taglist is a simple array of the tags for the story,
+and an empty array if none are set.
 
 The default values for $prefix and $suffix are 'Tags: ' and '. ' 
 respectively, so a typical $taglist might look like:
