[Ludovic Courtès]

Hello!

Andy Wingo <address@hidden> skribis:

Please add (G_ …) for i18n, and also add the file to po/guix/POTFILES.in.

I’ll email guix-sysadmin so potluck.guixsd.org points to the same IP as
guix-potluck.org.  :-)

‘parse-command-line’ honors $GUIX_BUILD_OPTIONS, which is unnecessary
here.  Instead, we should use ‘args-fold*’ like in (guix scripts hash),
for instance.

Otherwise LGTM, thanks!
