=head1 list-ports.pl
Lists TCP ports associated with some virtual server
This command lists all TCP ports in use by or allowed to be used by the
virtual server selected with the C<--domain> flag. To output a list of just
port numbers, use the C<--port-only> flag. Or to show the full details of
each port, use C<--multiline>.
