# To play around with this some more, try to:

# - create an empty translation:
# cp po/ubuntu-packaging-guide.pot po/xx.po
# - run the script and see if it works and just takes the translations
# above the threshold (PERCENTAGE variable)
# - make sure you don't accidentally commit changes to the packaging
