Changing URI segments in Code Ingniter

[eluser]tomcode[/eluser]
In my latest site I used a customized Router class based on this Wiki entry, I put the changed Router.php into the application library folder.

Before I used a central MY_Controller with a Controller foreach language, which would set the language and then use the methods of MY_Controller, suitable for small sites, very readable and fast.

Another method using routes is described in the Wiki by wiredesignz
