Entity XLIFF FTP is a Drupal extension that introduces a localization workflow whereby editors or administrators can push XLIFF files to a remote server via SFTP, then pull down processed XLIFF files when they're ready (either manually, or automatically on cron).
This extension was designed specifically to work with SDL WorldServer, but can theoretically be used with any FTP server or FTP-enabled translation management system.
This module aims to ease the deployment of translation .PO files that the great Potx module generates. No longer will you have to manually upload these files to keep your site translations up to date. You can manually batch import all PO files defined in custom modules or alternatively, you can use the always useful Drush command to make things easier for you.
