* Controller mappings.
*
* For each controller name, we associate a controller file to be found in /inc/ .
* The advantage of this indirection is that it is easy to reorganize the controllers into
* subdirectories by modules. It is also easy to deactivate some controllers if you don't
* want to provide this functionality on a given installation.
*
* Note: while the controller mappings might more or less follow the menu structure, we do not merge
* the two tables since we could, at any time, decide to make a skin with a different menu structure.
* The controllers however would most likely remain the same.
