+=head1 NAME
+
+Apache::lonroles - User Roles Screen
+
+=head1 SYNOPSIS
+
+Invoked by /etc/httpd/conf/srm.conf:
+
+
+ PerlAccessHandler Apache::lonacc
+ SetHandler perl-script
+ PerlHandler Apache::lonroles
+ ErrorDocument 403 /adm/login
+ ErrorDocument 500 /adm/errorhandler
+
+
+=head1 OVERVIEW
+
+=head2 Choosing Roles
+
+C is a handler that allows a user to switch roles in
+mid-session. LON-CAPA attempts to work with "No Role Specified", the
+default role that a user has before selecting a role, as widely as
+possible, but certain handlers for example need specification which
+course they should act on, etc. Both in this scenario, and when the
+handler determines via C's C<&allowed> function that a certain
+action is not allowed, C is used as error handler. This
+allows the user to select another role which may have permission to do
+what they were trying to do.

+=end latex
+
+=head2 Role Initialization
+
+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'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.
+
+=head1 INTRODUCTION
+
+This module enables a user to select what role he wishes to
+operate under (instructor, student, teaching assistant, course
+coordinator, etc). These roles are pre-established by the actions
+of upper-level users.
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
+
+=head1 HANDLER SUBROUTINE
+
+This routine is called by Apache and mod_perl.
