+A page written in the "master" language is a "master" page, and is
+written in any supported format but PO. It does not have to be named
+a special way: migration from/to this plugin does not imply heavy
+renaming work.
Example: `bla/page.mdwn` is a "master" Markdown page written in
English; if `usedirs` is enabled, it is rendered as
\[[!map pages="dev/* and lang(LL)" feeds="no"]]
+ \[[!map pages="dev/* and currentlang()" feeds="no"]]
