# This script pulls translations from weblate.
#
# It squashes all the changes into a single commit. This removes authorship
# from the changes, which is given to the Translatebot, so to keep the names
# they are grabbed from git log and added to the commit message.
#
# Note that this will apply changes and commit them! Make sure to not have
# uncommited changes when running this script.
#
# Note 2: after applying changes, files will be cleaned up before committing.
