600: =head1 OVERVIEW
601:
602: =head2 Choosing Roles
603:
604: C<lonroles> is a handler that allows a user to switch roles in
605: mid-session. LON-CAPA attempts to work with "No Role Specified", the
606: default role that a user has before selecting a role, as widely as
607: possible, but certain handlers for example need specification which
608: course they should act on, etc. Both in this scenario, and when the
609: handler determines via C<lonnet>'s C<&allowed> function that a certain
610: action is not allowed, C<lonroles> is used as error handler. This
611: allows the user to select another role which may have permission to do
612: what they were trying to do. C<lonroles> can also be accessed via the
613: B<CRS> button in the Remote Control.

626: =head2 Role Initialization
627:
628: 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.
629:
630: =head1 INTRODUCTION
631:
632: This module enables a user to select what role he wishes to
633: operate under (instructor, student, teaching assistant, course
634: coordinator, etc). These roles are pre-established by the actions
635: of upper-level users.
636:
637: This is part of the LearningOnline Network with CAPA project
638: described at http://www.lon-capa.org.
