1097: =head1 OVERVIEW
1098:
1099: =head2 Choosing Roles
1100:
1101: C<lonroles> is a handler that allows a user to switch roles in
1102: mid-session. LON-CAPA attempts to work with "No Role Specified", the
1103: default role that a user has before selecting a role, as widely as
1104: possible, but certain handlers for example need specification which
1105: course they should act on, etc. Both in this scenario, and when the
1106: handler determines via C<lonnet>'s C<&allowed> function that a certain
1107: action is not allowed, C<lonroles> is used as error handler. This
1108: allows the user to select another role which may have permission to do
1109: what they were trying to do. C<lonroles> can also be accessed via the
1110: B<CRS> button in the Remote Control.

1123: =head2 Role Initialization
1124:
1125: The privileges for a user are established at login time and stored in the session environment. As a consequence, a new role does not become active till the next login. Handlers are able to query for privileges using C<lonnet>'s C<&allowed> function. When a user first logs in, their role is the "common" role, which means that they have the sum of all of their privileges. During a session it might become necessary to choose a particular role, which as a consequence also limits the user to only the privileges in that particular role.

1127: =head1 INTRODUCTION
1128:
1129: This module enables a user to select what role he wishes to
1130: operate under (instructor, student, teaching assistant, course
1131: coordinator, etc). These roles are pre-established by the actions
1132: of upper-level users.
