Apache::loncoursequeueadmin.pm
=head1 SYNOPSIS
Utilities used by domain coordinators to administer queued course creation requests,
and by course coordinators for queued self-enrollment requests, and by general
users to display their queued self-enrollment requests.
This is part of the LearningOnline Network with CAPA project
described at http://www.lon-capa.org.
