Oh you need the .mo files so you can ‘bindtextdomain’ hmmm…

It would be easier if the web site used the inferior API; you would
delegate translation to the inferior and that’s it.

So we copy them for the sake of ‘bindtextdomain’, right?

In practice those .mo files should be the same as what you’d get via
‘latest-guix’ so that’s probably fine.

Why “lingua” and “lang” BTW?
