locale.module in Zircon Profile 8
Same filename and directory in other branches
Enables the translation of the user interface to languages other than English.
When enabled, multiple languages can be added. The site interface can be displayed in different languages, and nodes can have languages assigned. The setup of languages and translations is completely web based. Gettext portable object files are supported.
