#
# This python file contains utility scripts to manage Django translations.
# It has to be run inside the django git root directory.
#
# The following commands are available:
#
# * update_catalogs: check for new strings in core and contrib catalogs, and
# output how much strings are new/changed.
#
# * lang_stats: output statistics for each catalog/language combination
#
# * fetch: fetch translations from transifex.com
#
# Each command support the --languages and --resources options to limit their
# operation to the specified language or resource. For example, to get stats
# for Spanish in contrib.admin, run:
#
# $ python scripts/manage_translations.py lang_stats --language=es --resources=admin
