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.
