Nit: it's nice to have an empty line after the top comment.

[Tudor Avram, 2018/10/04 06:48:03]

Done.

What if this fails after all the retries? Above you catch the exception and do
sys.exit() -- is there a reason to do it differently here?

Done.

Nope. I just forgot to add that here :D

but source.list_locales()?

[Tudor Avram, 2018/10/04 06:48:03]

As we discussed in person, I wrote that method because `source.list_locales()`
ignores locales for which the corresponding directory is empty. And I think that
would be the case especially for cases when we want to add new languages to a
website.

Maybe this function would fit better in translate_xtm_cloud.py -- it's basically
doing routing anyway and there it would be easier to see what's in
args.projects_func, so it would be easier to read it.

Done.
