+----------------------------------
+
+We can get all users and their roles for a certain context
+object. This even works for objects that cannot have local roles as
+they are not stored in the ZODB:
+
+    >>> from waeup.sirp.permissions import get_users_with_local_roles
+    >>> mycontext = object()
+    >>> people_and_roles = get_users_with_local_roles(mycontext)
+    >>> people_and_roles
+    <generator object at 0x...>
+
+In this case, the result is empty:
+
+    >>> people_and_roles = list(people_and_roles)
+    >>> people_and_roles
+    []
