+This modules allows to select a default language which is used for source terms in translations.
+Any update done with this default_language will be taken as source in translations
+and written in object directly.
+Also when updating a translatable term, all existing translations (but default language) will be set to to_translate
+
+This module is useless in case your main language is en_US or in case you have only 1 language installed
+(in thoses cases, Odoo performs correctly).

+To use this module, you need to:
