+=head1 NAME
+
+storytags - blosxom plugin to format a per-story $storytags::taglist string
+
+=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).
+
+The default values for $prefix and $suffix are 'Tags: ' and '. ' 
+respectively, so a typical $taglist might look like:
+
+    Tags: dogs, cats, pets.
+
+=head1 USAGE
+
+L<storytags> requires the L<tags> plugin, and should be loaded AFTER
+L<tags>. It has no other ordering dependencies.
+
+=head1 ACKNOWLEDGEMENTS
+
+This plugin was inspired by xtaran's excellent L<tagging> plugin,
+which includes similar functionality.
