-I'd like to see some way to conditionally include wiki text based on whether the wiki enables or disables certain features.  For example, [[helponformatting]], could use `\[[if (enabled smiley) """Also, because this wiki has the smiley plugin enabled, you can insert \[[smileys]] and some other useful symbols."""]]`, and a standard template for [[plugins]] pages could check for the given plugin name to print "enabled" or "disabled".

 * `sourcepage pagespec`: true if pagespec includes the page corresponding to the file actually containing this content, rather than a page including it.
 * `included`: true if included on another page, via [[plugins/inline]], [[plugins/sidebar]], [[plugins/contrib/navbar]], etc.
 
-You may or may not want to include boolean operations (`and`, `or`, and `not`); if you do, you could replace `disabled` with `not enabled`, and `no pagespec` or `none pagespec` with `not any pagespec` (but you may want to keep the aliases for simplicity anyway).  You also may or may not want to include an `else` clause; if so, you could label the text used if true as `then`.

-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.
