The Translation Management Tool (TMGMT) module provides a tool set for translating content from different sources. The translation can be done by people or translation services of all kinds. It builds on and uses existing language tools and data structures in Drupal and can be used in automated workflow scenarios.
This module does not make i18n or any other language module for Drupal obsolete. It does only facilitate the translation process.
It does provide a controlled process through which a translation job can run his translation items. You can have multiple sources of text for translation, running them through translators of your choice. Human or machine.
Several sources and translation services are available. Additional sources and translators can be added through a pluggable architecture.
