The Transifex Command-line Client is a command line tool that enables
you to easily manage your translations within a project without the
need of an elaborate UI system.
You can use the command line client to easily create new resources,
map locale files to translations and synchronize your Transifex project
with your local repository and viceversa.
Translators and localization managers can also use it to handle large
volumes of translation files easily and without much hassle.
