 I'd like to see some way to include certain files from the underlay only when the wiki has certain plugins enabled.  For example:
 
 * Only include smileys.mdwn and the smileys subdirectory if you enable the [[plugins/smiley]] plugin.

+I can see two good ways to implement this.  Ideally, with
+[[conditional_text_based_on_ikiwiki_features]] available, ikiwiki could
+parse a page like conditionalpages.mdwn, which could contain a set of
+conditional-wrapped page names; that seems like the most elegant and
+ikiwiki-like approach.  Alternatively, ikiwiki.setup could contain a
+Perl-generated exclude option by default; that would work, but it seems
+hackish.
