 package Apache::loncreateuser;
 
+=pod
+
+=head1 NAME
+
+Apache::loncreateuser.pm
+
+=head1 SYNOPSIS
+
+    Handler to create users and custom roles
+
+    Provides an Apache handler for creating users,
+    editing their login parameters, roles, and removing roles, and
+    also creating and assigning custom roles.
+
+=head1 OVERVIEW
+
+=head2 Custom Roles
+
+In LON-CAPA, roles are actually collections of privileges. "Teaching
+Assistant", "Course Coordinator", and other such roles are really just
+collection of privileges that are useful in many circumstances.
+
+Custom roles can be defined by a Domain Coordinator, Course Coordinator
+or Community Coordinator via the Manage User functionality.
+The custom role editor screen will show all privileges which can be
+assigned to users. For a complete list of privileges, please see 
+C</home/httpd/lonTabs/rolesplain.tab>.
+
+Custom role definitions are stored in the C<roles.db> file of the creator
+of the role.
