+#!/usr/bin/perl
+#  
+#  This script uses the named D-BUS support, which must be enabled in
+#  the running named with the named '-D' option, to get and print the
+#  list of forwarding zones in the running server.
+#
+#  It accepts an optional <zone> first argument which is the DNS name
+#  of the zone whose forwarders (if any) will be retrieved.
+#
+#  If no zone argument is specified, all forwarding zones will be listed.
+#
+#  Usage: GetForwarders [-n -r] [ <zone> ]
+#    -n : output forward zone statements for named.conf
+#    -r : output in resolv.conf format
+#       : no -r or -n: just list the forwarders
