============
A language is chosen as the "master" one, and any other supported
-language is a "slave" one. A page written in the "master" language is
-a "master" page, and is written in any supported format but PO.
+language is a "slave" one.

+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
TODO

+-----
+
+Choice between two behaviors must be possible in `ikiwiki.setup`;
+a `po_link_to_current_language` option must allow switching
+between them.
+
+If `po_link_to_current_language` is disabled, `[[page]]` links to the
+negotiated preferred language, i.e.:
+
+- `usedirs` enabled: `bla/page/`
+- `usedirs` disabled: `bla/page`
+
+This obviously does not work in case Content Negotiation is not
+supported by the web server, hence one can enable
+`po_link_to_current_language` to make `[[page]]` link to the current
+page's language, i.e.:
+
+- `usedirs` enabled: `bla/page/index.LL.html`
+- `usedirs` disabled: `bla/page.LL.html`
+
+**FIXME**: should `po_link_to_current_language` be enabled by default?

Display available translations
------------------------------
To improve user navigation in a multi-lingual wiki, site developers
must be enabled to write:
- \[[!map pages="dev/* and preferredlang()" feeds="no"]]
+ \[[!map pages="dev/* and lang(LL)" feeds="no"]]
\[[!map pages="dev/* and currentlang()" feeds="no"]]
-Some new [[ikiwiki/pagespec]] functions have to be written.
