Thank you very much for telling me about the repository.  I also got an
idea of the translation flow in Guix using Weblate; Weblate refers to
and updates the PO files in the Guix-translations repository, and that
the PO files in the Guix.git cloned in it are updated by the Makefile.

The changes in revision 2 don't alter the location of PO files and the
scripts under the scripts directory.  I couldn't find additional changes
to the po4a.cfg and the Makefiles.

What do you think, Julien Lepiller?  If there are any changes that
should be made, I would appreciate it if you could correct me.

The po4a.cfg added by this change allows quite flexible specification of
file paths by passing variables (with po4a's "--variable key=value"
option.)  It would be therefore possible to make the Guix-translations
repository also use the integrated po4a program anytime.  The Texinfo
parser used by po4a (and po4a-* scripts) is the same before and after
the change, so there should be no side-effect on the PO files.

When I was writing this, I noticed that I have transferred some
configuration to po4a.cfg and now there is one more place to specify the
languages (in the po4a_langs section.)  The documentation will need to
be updated in the future in this respect.

gemmaro.
