=head1 NAME
Apache::loncreateuser - handler to create users and custom roles
=head1 SYNOPSIS
Apache::loncreateuser 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.
Creating custom roles can be done by the Domain Coordinator through
the Create User functionality. That screen will show all privileges
that 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 role
author.
