this is the program I recently wrote, that generated
the submodule entries for the GRUB PO file fix

this utility is for reference only. i'll probably do
away with the fix at some point, replacing it with
my own git-based submodule repository, containing the
PO files. this would make things easier, and then
that repository would contain the utility instead.

i'm just putting this in lbmk for now, so that we
have it somewhere.
