# A simple script that adds all authors from transifex, which are
# listed in comments at the beginning of the file, to the
# 'translator-credits' translations - where launchpad added them
# and which are shown in stk.
#
# Usage: update_po_authors.py PATH_TO/LANGUAGE.po
#
# IMPORTANT note: this script must be run on a file downloaded
# from transifex, not on a file on which this script had
# been run before (otherwise the transifex authors would
# be added again and again)!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
#
# Less important note: The specified file is overwritten without
# a backup! Make sure the git status is unmodified.
