+# Usage: ditch.pl [-s <address>] [-p <port>] [filename]
+#
+# Input (in filename, if specified, otherwise stdin) is a series of one
+# or more DNS names and types to send as queries, e.g.:
+#
+# www.example.com A
+# www.example.org MX
+#
+# If not specified, address defaults to 127.0.0.1, port to 53.
