* ``$PYTHONPATH/django/conf/locale/<language>/LC_MESSAGES/django.(po|mo)``
To create message files, you use the :djadmin:`django-admin.py makemessages <makemessages>`
tool. You only need to be in the same directory where the ``locale/`` directory
is located. And you use :djadmin:`django-admin.py compilemessages <compilemessages>`
tool. And you use :djadmin:`django-admin.py compilemessages <compilemessages>`
to produce the binary ``.mo`` files that are used by ``gettext``.
You can also run :djadmin:`django-admin.py compilemessages
--settings=path.to.settings <compilemessages>` to make the compiler process all
the directories in your :setting:`LOCALE_PATHS` setting.
Finally, you should give some thought to the structure of your translation
files. If your applications need to be delivered to other users and will be used
in other projects, you might want to use app-specific translations. But using
app-specific translations and project-specific translations could produce weird
problems with :djadmin:`makemessages`: it will traverse all directories below
the current path and so might put message IDs into a unified, common message
file for the current project that are already in application message files.
The easiest way out is to store applications that are not part of the project
(and so carry their own translations) outside the project tree. That way,
:djadmin:`django-admin.py makemessages <makemessages>`, when ran on a project
level will only extract strings that are connected to your explicit project and
not strings that are distributed independently.
