=============

+Supported languages

+`po_master_language` is used to set the "master" language in
`ikiwiki.setup`, such as:
po_master_language => { 'code' => 'en', 'name' => 'English' }
translatable. It is a [[ikiwiki/PageSpec]], so you have lots of
control over what kind of pages are translatable.

Internal links

+The `po_link_to` option in `ikiwiki.setup` is used to decide how
internal links should be generated, depending on web server features

language's page.
+### Link to current language
+
+If `po_link_to` is set to `current`, `\[[destpage]]` links to the
+`destpage`'s version written in the current page's language, if
+available, *i.e.*:
+
+- `foo/destpage/index.LL.html` if `usedirs` is enabled
+- `foo/destpage.LL.html` if `usedirs` is disabled
+
### Link to negotiated language
If `po_link_to` is set to `negotiated`, `\[[page]]` links to the
(In)compatibility notes:
-- `po_link_to => negotiated` provides no useful behavior if `usedirs`
- is disabled; this option combination is neither implemented nor
- allowed
-- `po_link_to => negotiated` provides no useful behavior if the web
- server does not support Content Negotiation
-
-### Link to current language
-
-If `po_link_to` is set to `current` and the destination page is either
-a translatable page or a translation, `\[[page]]` links to the current

versions of the same page, and the translations' status.

- `PERCENT` - for "slave" pages, is set to the translation completeness, in percents

-------------------

-Should pages using the `OTHERLANGUAGES` template loop be declared as
-linking to the same page in other versions?

-View translation status
------------------------
-
-One should be able to view some information about the translation
-completeness, either for a given page or for the whole wiki.
+OTHERLANGUAGES dependencies
+---------------------------
-This should not be too hard using gettext tools. If this is

+Pages using `OTHERLANGUAGES` must depend on any "master" and "slave"
+pages whose status is being displayed. It will trigger dependency
