I only know transifex in practice, so my comments below will be biased
a bit towards that direction.

You need to explicitely "tx push" the changed strings to transifex and
give the translators a bit time to translate. This means before the
actual release of a new version, the StringFreeze needs to happen,
where you only move code around, but don't change any _("") strings
Just before the release "tx pull" will get the translations back again
and you can include them into the tar ball for downloading (I'm
unsure, if they need to be committed into git or if including into a
tarball is sufficient).

I'd suggest a string freeze, before each new release, so translators
have a bit time to translate the development version.
(Regularly pushing changed strings to tx would help to always keep a
low number of needed translation strings.)

I cannot remember a project, which splits the translations into
another repository off hand...
It might be good to split the translations of the webpage, as that
might become quite big and is normally not needed in a tarball (if you
want to let translate the webpage too...)

They expect setup.py to compile the .po file into a .mo files and
install them into:
/usr/share/locale/$LANG/LC_MESSAGES/ipython.mo (when you use
Some quick googling showed this as an example for compiling the translations:
Hope that helps.
