+[[Templates|wikitemplate]] are filled out for many different things in

 The most common thing to do is probably to call `$template->param()` to add
 a new custom parameter to the template.

+used for a page in the wiki. The hook is passed a "page" parameter, and
+should return the name of the template file to use, or undef if it doesn't
+want to change the default ("page.tmpl"). Template files are looked for in
+/usr/share/ikiwiki/templates by default.
