Listing translated locales in Flask-Babel

I'm working on a pastebin application, and while I don't have the
infrastructure fully ready to be translated yet, I'm wondering how I can
get a list of languages that do actually have translations. (i.e.
something that will check the 'translations' folder for me and read the
languages there.) Right now, I'm considering either:

- Having a hardcoded list of AVAILABLE_LANGUAGES in the code
- Manually 'os.listdir'-ing the 'translations' folder and taking
anything that is a directory

The second one is a bit low-level and kludgy for my tastes, and the
first one would be a slight maintenance headache. Sadly, I can't find
out much from the Babel docs, so does anyone know of a function that can
do that? (Or, better yet, add said functionality to Flask-Babel?)

Easy method, not that bad either because you can explicitly disable 
translations that are not up-to-date.

Babel itself does not handle gettext loading because you could load 
translations from pretty much anywhere if you like (for example files in 
/usr/local/translations or even a database).

However Flask-Babel does suggest a specific place for these so it makes 
a lot of sense to add a method to list translations.  I will add one.
