=head1 CONFIGURATION

This script is designed to be run on a machine with an active RT instance,
otherwise it will not work!

Also, for this script to do anything useful, reasonable values for
SENDER, RECIPIENT, and USERS should be defined in the configuration
file /etc/sysconfig/perl-RT-admin-tools

See the comments embedded in that file for more information.
