In my specific use-case, I'm not only merging translations from core +
plugins, but also allowing to customize the merged translations, so
the Makefile came in handy to handle "recompilation" only of the
changed parts, etc.

Of course, it would be possible to create a paster command that does
something like this:

- - aggregate translations from core + plugins (this part needs some
care, as the correct procedure is to merge POTs first, and then merge
translations in the newly created POT)

- - install new translation PO files in ckan.i81n_directory (and compile
them to MO)

It should be possible to do all the paths discovery automatically, by
just passing the path to ckan configuration file.

I'd use the order in which plugins are listed in configuration file,
for that.



If we all agree on the creation of a new paster command for merging
translations, I'm going to write that and send a PR.


Cheers
