/**
 * XOrg's Hooks API
 *
 * Hooks are used in modules to allow modules that depends upon us to hook
 * themselves in our core functionnalities.
 *
 * Every module will use some hools, and define their names.
 * Pretend Ť myhook ť is one of those names, then :
 *  - hooks/myhook/API has to exists, and will explain the API of the hook
 *  - every module "mod" may have a file hooks/myhook/mod.inc.php that implements
 *    fully or partially the API of the hook.
 *
 * If the hook's API has to change, the functions that change MUST change their
 * name to avoid any compatibility problem.
