1088: =head1 OVERVIEW
1089:
1090: =head2 Choosing Roles
1091:
1092: C<lonroles> is a handler that allows a user to switch roles in
1093: mid-session. LON-CAPA attempts to work with "No Role Specified", the
1094: default role that a user has before selecting a role, as widely as
1095: possible, but certain handlers for example need specification which
1096: course they should act on, etc. Both in this scenario, and when the
1097: handler determines via C<lonnet>'s C<&allowed> function that a certain
1098: action is not allowed, C<lonroles> is used as error handler. This
1099: allows the user to select another role which may have permission to do
1100: what they were trying to do. C<lonroles> can also be accessed via the
1101: B<CRS> button in the Remote Control.

1114: =head2 Role Initialization
1115:
1116: 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.

1118: =head1 INTRODUCTION
1119:
1120: This module enables a user to select what role he wishes to
1121: operate under (instructor, student, teaching assistant, course
1122: coordinator, etc). These roles are pre-established by the actions
1123: of upper-level users.
