-Sessions
-========
-
-There are three kinds of sessions.
-
-* `user sessions` are the most common: they are related to users and
-  carry security checks coming with user credentials
-
-* `super sessions` are children of ordinary user sessions and allow to
-  bypass security checks (they are created by calling unsafe_execute
-  on a user session); this is often convenient in hooks which may
-  touch data that is not directly updatable by users
-
-* `internal sessions` have all the powers; they are also used in only a
-  few situations where you don't already have an adequate session at
-  hand, like: user authentication, data synchronisation in
-  multi-source contexts
-
-.. note::
-  Do not confuse the session type with their connection mode, for
-  instance : 'in memory' or 'pyro'.
