URI Language Identifier

Category:Core Extensions::Language Category:Libraries::Language

This language class extension allows you to automatically prefix all site urls with a language abbreviation that is pre-defined in your config file or from a link and automatically load the corresponding language translation file, the route will then be corrected by the route regex for everything to work as normal.

Somewhere in the site you can provide the user with links allowing them to change their desired language name.
