Automatic PO files update
-------------------------
-Committing changes to a "master" page must:
+Committing changes to a "master" page:
-1. update the POT file and the PO files for the supported languages,
- before putting them under version control
-2. trigger a refresh of the corresponding HTML slave pages
+1. updates the POT file and the PO files for the supported languages;
+ this is done in the `needsbuild` hook; **FIXME**: the updated PO
+ files must then be put under version control
-The former is to be done at a time when:
+2. triggers a refresh of the corresponding HTML slave pages: this is
+ achieved by making any "slave" page dependent on the corresponding
+ "master" page, in the `needsbuild` hook.
-- we know which "master" page was modified, and thus, which POT/PO
- files have to be updated: the `needsbuild` hook is the first one to
- run that provides us with the necessary information
-- we can modify the list of pages needing a refresh; this is
- `needsbuild` hook's job
+**FIXME** Also, when the plugin has just been enabled:
-The latter can be implemented by making any "slave" page depend on the
-corresponding "master" page. The `add_depends` function can achieve
-this, if used in a **FIXME** hook.
+- all the needed POT and PO files have to be created
+- the PO files must be checked into version control
UI consistency: rename "Edit" button on slave pages
