This questions comes from noticing locales aren't detected on Watcher
and many other OpenStack projects when `python setup.py install` is
executed. The behavior of installing and detecting locales seems to be
the same both inside and without a virtualenv.

On  Watcher we do not have a MANIFEST.in file in the repository, what
would such a file look like do you perhaps have a reference?

Currently I was thinking of doing something like this:

data_files =
    usr/share/locale/nl/LC_MESSAGES =

This, however, feels clunky and I would expect locale installation and
detection to be more automatic.

you can test if locales are detected for a project using:


In the case of Watcher this only returns `['en_US']` which is inserted
as default.

Maybe `python setup.py install` is not the right command to install locales?

Kind regards,
