1069: =head1 OVERVIEW
1070:
1071: =head2 Choosing Roles
1072:
1073: C<lonroles> is a handler that allows a user to switch roles in
1074: mid-session. LON-CAPA attempts to work with "No Role Specified", the
1075: default role that a user has before selecting a role, as widely as
1076: possible, but certain handlers for example need specification which
1077: course they should act on, etc. Both in this scenario, and when the
1078: handler determines via C<lonnet>'s C<&allowed> function that a certain
1079: action is not allowed, C<lonroles> is used as error handler. This
1080: allows the user to select another role which may have permission to do
1081: what they were trying to do. C<lonroles> can also be accessed via the
1082: B<CRS> button in the Remote Control.

1095: =head2 Role Initialization
1096:
1097: 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.

1099: =head1 INTRODUCTION
1100:
1101: This module enables a user to select what role he wishes to
1102: operate under (instructor, student, teaching assistant, course
1103: coordinator, etc). These roles are pre-established by the actions
1104: of upper-level users.
