1136: =head1 OVERVIEW
1137:
1138: =head2 Choosing Roles
1139:
1140: C<lonroles> is a handler that allows a user to switch roles in
1141: mid-session. LON-CAPA attempts to work with "No Role Specified", the
1142: default role that a user has before selecting a role, as widely as
1143: possible, but certain handlers for example need specification which
1144: course they should act on, etc. Both in this scenario, and when the
1145: handler determines via C<lonnet>'s C<&allowed> function that a certain
1146: action is not allowed, C<lonroles> is used as error handler. This
1147: allows the user to select another role which may have permission to do
1148: what they were trying to do. C<lonroles> can also be accessed via the
1149: B<CRS> button in the Remote Control.

1162: =head2 Role Initialization
1163:
1164: 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.

1166: =head1 INTRODUCTION
1167:
1168: This module enables a user to select what role he wishes to
1169: operate under (instructor, student, teaching assistant, course
1170: coordinator, etc). These roles are pre-established by the actions
1171: of upper-level users.
