This module is a Drupal Permission Redistribution System, so when you are using permission control module, there is a permission assignment page which has limited perms you selected, and an administrator who is not Drupal Admin could grant perms to others.
It is very good for an sub-administrator who is not drupal admin, but who needs privilege to grant some perms to some role. Such as OA admin, Department Admin, etc.
