# Sync our translations.
#
# The sync process has 3 different steps:
#
# 1. Generates the message.pot file: it gets all the php files, parses them
#    and find all the strings that are tagged.
#
# 2. Send the pot file to POEditor.
#
# 3. Retrieve from POEditor all the po files for each language we're supporting,
#    allowing us to keep our codebase in sync.
