+If the [[po|plugins/po]] plugin is enabled, the regular
+[[ikiwiki/PageSpec]] syntax is expanded with the following additional
+tests that can be used to improve user navigation in a multi-lingual
+wiki:
+
+* "`lang(LL)`" - Tests whether a page is written in the language
+ specified as a ISO639-1 (two-letter) language code.
+* "`currentlang()`" - Tests whether a page is written in the same
+ language as the current page.

+Note: every non-po page is considered to be written in
+`po_master_language`, as specified in `ikiwiki.setup`.
