+## Internal use pages

+Sometimes it's useful to put pages in the wiki without the overhead of

+are collected together to form the RecentChanges page, for example.

+with "_". Internal use pages cannot be edited with the web interface,
+generally shouldn't contain wikilinks or preprocessor directives (use
+either on them with extreme caution), and are not matched by regular
+PageSpecs glob patterns, but instead only by a special `internal()`
+[[ikiwiki/PageSpec]].
