#
# This script has two options:
# --push
#     1. refresh translation files (*.ts) from source
#     2. upload source language (en_US) to Transifex for translation
# --pull
#     1. download translations from Transifex leaving directly maintained files untouched
#     2. modify Transifex generated *.ts files
#
# Manually:
# 3. review and commit changes to SCM
#
# Prerequisite:
# * have the Transifex client installed (http://docs.transifex.com/client/setup)
#   and configured (http://docs.transifex.com/client/config).
# * user needs to have maintainer priviledges to the Transifex project
# * configure languages not to be updated from Transifex (e.g. because
#   translations arrive in SCM directly) in the DIRECTLY_MAINTAINED list.
