"""The SU app is used to change the current logged in user on-the-fly.
In order to achieve this goal, the module introduces concept of *effective*
and *real* user privileges known from Unix-like systems. The *effective*
user is stored in ``request.user`` field, while the *real* in
``request.real_user``.
On-the-fly means that current session variables are preserved while changing
*effective* user, which may be also a pitfall if some code stores
there data directly connected with current user scope.
