# Dynamic update test suite.
#
# Usage:
#
#   perl update_test.pl [-s server] [-p port] zone
#
# The server defaults to 127.0.0.1.
# The port defaults to 53.
#
# The "Special NS rules" tests will only work correctly if the
# has no NS records to begin with, or alternatively has a
# single NS record pointing at the name "ns1" (relative to
# the zone name).
#
# Installation notes:
#
# This program uses the Net::DNS::Resolver module.
# You can install it by saying
#
#    perl -MCPAN -e "install Net::DNS"
