`po_slave_languages` is used to set the list of supported "slave"
languages, such as:
- po_slave_languages => { 'fr' => 'Français',
- 'es' => 'Español',
- 'de' => 'Deutsch',
- }
+ po_slave_languages => [ 'fr|Français',
+ 'es|Español',
+ 'de|Deutsch',

Decide which pages are translatable
-----------------------------------
Using Apache `mod_negotiation` makes it really easy to have Apache
serve any page in the client's preferred language, if available.
-This is the default Debian Apache configuration.

+Add 'Options MultiViews' to the wiki directory's configuration in Apache.
When `usedirs` is enabled, one has to set `DirectoryIndex index` for
the wiki context.
language code) for the wiki context can help to ensure
`bla/page/index.en.html` is served as `Content-Language: LL`.
+For details, see [Apache's documentation](http://httpd.apache.org/docs/2.2/content-negotiation.html).

lighttpd
--------
-lighttpd unfortunately does not support content negotiation.
+Recent versions of lighttpd should be able to use
+`$HTTP["language"]` to configure the translated pages to be served.
-**FIXME**: does `mod_magnet` provide the functionality needed to
- emulate this?

Likewise, "slave" pages are not supposed to have sub-pages;
-[[WikiLinks|wikilink]] that appear on a "slave" page therefore link to
+[[WikiLinks|ikiwiki/wikilink]] that appear on a "slave" page therefore link to
the master page's sub-pages.

+BUGS
====
-Better links
-------------
-
-Once the fix to
-[[bugs/pagetitle_function_does_not_respect_meta_titles]] from
-[[intrigeri]]'s `meta` branch is merged into ikiwiki upstream, the
-generated links' text will be optionally based on the page titles set
-with the [[meta|plugins/meta]] plugin, and will thus be translatable.
-It will also allow displaying the translation status in links to slave
-pages. Both were implemented, and reverted in commit
-ea753782b222bf4ba2fb4683b6363afdd9055b64, which should be reverted
-once [[intrigeri]]'s `meta` branch is merged.
+[[!inline pages="bugs/po:* and !bugs/done and !link(bugs/done) and !bugs/*/*"
+feeds=no actions=no archive=yes show=0]]
-An integration branch, called `meta-po`, merges [[intrigeri]]'s `po`
-and `meta` branches, and thus has thise additional features.

-Language display order
-----------------------
-
-Jonas pointed out that one might want to control the order that links to
-other languages are listed, for various reasons. Currently, there is no
-order, as `po_slave_languages` is a hash. It would need to be converted
-to an array to support this. (If twere done, twere best done quickly.)

-po files in underlay
---------------------
-
-I think this plugin doesn't yet allow po files to be present in an
-underlay to translate files also from the underlay.
-
-In `istranslatablefile`, it specifically checks that
-the file is present in srcdir.
+TODO
+====
-Problem with this is that it precludes using po to translate
-the basewiki (work which is well under way for Danish BTW),
-since the translated po files cannot really be used.
+[[!inline pages="todo/po:* and !todo/done and !link(todo/done) and !todo/*/*"
+feeds=no actions=no archive=yes show=0]]
-A further problem comes if one wants to use a non-English language as the
-`po_master_language`. It would be good to get a translated
-basewiki, taking po files from the underlay and using them as the primary
-page sources, but this plugin doesn't yet support that.
+broken links to translatable basewiki pages that lack po files
+--------------------------------------------------------------
-And, maybe it shouldn't? A user would not expect to see a po file when
-editing the index page of their wiki, just because they're using a
-different language. Instead, we might want to build localized .mdwn files
-for the basewiki, and then ikiwiki would just use that translated underlay.
-The when the user edits index, they get a nice mdwn file to start from.
+If a page is not translated yet, the "translated" version of it
+displays wikilinks to other, existing (but not yet translated?)
+pages as edit links, as if those pages do not exist.
-So, we seem to have two cases, in one po files from the underlay should be
-used, in the other not. Hmm. Support both?
---[[Joey]]
+That's really confusing, especially as clicking such a link
+brings up an edit form to create a new, english page.
-Duplicate %links ?
-------------------
+This is with po_link_to=current or negotiated. With default, it doesn't
+happen..
-I notice code in the scan hook that seems to assume
-that %links will accumulate duplicate links for a page.
-That used to be so, but the bug was fixed. Does this mean
-that po might be replacing the only link on a page, in error?
+Also, this may only happen if the page being linked to is coming from an
+underlay, and the underlays lack translation to a given language.

-Documentation
--------------
-
-Maybe write separate documentation depending on the people it targets:
-translators, wiki administrators, hackers. This plugin may be complex
-enough to deserve this.
