#!/bin/bash
#
#  This script uses the named D-BUS support, which must be enabled in
#  the running named with the named '-D' option, to set the forwarding zones
#  in the running server.
#  
#  One zone argument is required, followed by any number of server IP (v4 or v6)
#  addresses. If the server IP address list is empty, any forwarders for the zone
#  will be removed.
#
#  Usage:
#        SetForwarders [ -t <'first' | 'only'> ] <zone> [ <server IP> [...<server IP>] ]
