# 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
