 TODO
 ====
 
-Link relationships
-------------------
+OTHERLANGUAGES dependencies
+---------------------------
 
-Should pages using the `OTHERLANGUAGES` template loop be declared as
-linking to the same page in other versions?
+Pages using `OTHERLANGUAGES` must depend on any "master" and "slave"
+pages whose status is being displayed. It will trigger dependency
+loops; how to sort this out?
 
-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.
-
-This should not be too hard using gettext tools. If this is
-implemented as a
-[HTML::Template](http://search.cpan.org/search?mode=dist&query=HTML%3A%3ATemplate)
-loop, a page using it should depend on any "master" and "slave" pages
-whose status is being displayed.
-
-If it's not too heavy to compute, this status data may be made
-available in the `OTHERLANGUAGES` template loop; else, a dedicated
-loop would be needed.
+Should pages using the `OTHERLANGUAGES` template loop be declared as
+linking to the same page in other versions? To be rigorous, they
+should, but this may clutter the backlinks.
