+# 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
+# zone 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"
