+This plugin generates a hierarchical page map for the wiki. Example usage:
+
+	\[[map pages="* and !blog/*" maxdepth=2]]
+
+If the pages to include are not specified, all pages (and other files) in
+the wiki are mapped. If the maxdepth parameter is passed, only pages nested
+less than that many levels deep will be included in the map.
+
+This plugin is included in ikiwiki, but is not enabled by default.
+
+If this plugin is enabled, here is a page map for the plugins section
+of this wiki:
+
+[[map pages="plugins or plugins/*" maxdepth=3]]
+
+[[tag type/meta]]
