Open Stack

Hi guys,

I'm trying to get ceilometer consistent with the translation process of OpenStack, following http://wiki.openstack.org/Translations. I have some questions about the i18n process:

1. Do we have to manually add .pot and .po files into git repository? Or the Jenkins/Transifex can do it automatically?

2. The i18n process on the wiki suggests to put Babel dependency into pip-requires. Is it required to run a openstack service? My first impression is that Babel is only required to generate the gettext message catalog.

Best Regards,
