Internal links
--------------
+### Links targets
+
The `po_link_to` option in `ikiwiki.setup` is used to decide how
internal links should be generated, depending on web server features
and site-specific preferences.
-### Default linking behavior
+#### Default linking behavior
If `po_link_to` is unset, or set to `default`, ikiwiki's default
linking behavior is preserved: `\[[destpage]]` links to the master
language's page.
-### Link to current language
+#### 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
* `foo/destpage/index.LL.html` if `usedirs` is enabled
* `foo/destpage.LL.html` if `usedirs` is disabled
-### Link to negotiated language
+#### Link to negotiated language
If `po_link_to` is set to `negotiated`, `\[[page]]` links to the
negotiated preferred language, *i.e.* `foo/page/`.
* if the web server does not support Content Negotiation, setting
`po_link_to` to `negotiated` will produce a unusable website.
+### Links appearance
+
+When `po_translation_status_in_links` is enabled, the text of a link
+to a slave pages displays this page's translation status.
+
+When the `po_strictly_refresh_backlinks` setting is enabled, a page is
+refreshed every time a backlinked page is changed. This updates the
+translation status in links, and helps having a consistent translated
+wiki. Beware, this make every page depend on every page that links to
+it, which can slow everything down and bloat the dependency pagespecs.
