Find attached a work-in-progress patch to guix-artwork that constructs
PO entries from nested sexps.  Also attached is a file marked for
translation and the POT file generated from it.  No custom MO reader
is needed because gettext is a fine MO reader, the problem is only
xgettext that cannot extract sexps.  Currently missing though is a
procedure or macro for deconstructing the msgstr to an sexp, so the
patch can only generate unusable POT files at the moment.  I will take
a look at it now, but it may again take a week.  Please tell me if you
think this is the wrong approach.
