Hi Guix!

I was thinking we could have our news file translated at weblate, which
would help having more people translate it. Attached is a script that
is able to generate a pot file from the news.scm file and a translated
news.scm file from the existing news.scm and a directory that contains
the po files and a LINGUAS file.

The goal is to regularly fetch the news.scm file, generate a new pot
that would automatically be updated on weblate. Translators can do
their work, and the result is regularly merged back (after being
checked that it doesn't break) in our repo.

The script tries to reformat the news in a standard way and to merge
existing copyright lines with the authorship lines in the po files. It
is also able to generate the initial po files that I would give
weblate, so translators don't have to redo translations that have
already been done.

I also attached the LINGUAS file with all languages for which we have
at least one entry in news.scm.

WDYT?
