+This plugin allows inserting text generated by polygen into a wiki page.
+For example:

+It's also possible to specify a starting nonterminal for the grammar by

+If this plugin is enabled, and polygen is installed, here are a few notes
+about ikiwiki.

+----
+
+Ikiwiki is internally based on a [[polygen grammar="designpatterns"]]
+coupled to a [[polygen grammar="designpatterns"]], as described in
+"[[polygen grammar="paper2"]]" by [[polygen grammar="nipponame"]] of
+[[polygen grammar="boyband"]].
