+# This is a tool for sending an arbitrary packet via UDP or TCP to an
+# arbitrary address and port.  The packet is specified in a file or on
+# the standard input, in the form of a series of bytes in hexadecimal.
+# Whitespace is ignored, as is anything following a '#' symbol.
+#
+# For example, the following input would generate normal query for
+# isc.org/NS/IN":
+#
+#     # QID:
+#     0c d8
+#     # header:
+#     01 00 00 01 00 00 00 00 00 00
+#     # qname isc.org:
+#     03 69 73 63 03 6f 72 67 00
+#     # qtype NS:
+#     00 02
+#     # qclass IN:
+#     00 01
+#
+# Note that we do not wait for a response for the server.  This is simply
+# a way of injecting arbitrary packets to test server resposnes.
+#
+# Usage: packet.pl [-a <address>] [-p <port>] [-t (udp|tcp)] [filename]
+#
+# If not specified, address defaults to 127.0.0.1, port to 53, protocol
+# to udp, and file to stdin.
