+_akcom-udpecho_ is a shell utility for testing UDP echo servers. _akcom-udpecho_
+supports for RFC 862 compliant servers and TR-143 UDPEchoPlus compliant
+servers.  If the UDP Echo variant is not specified, _akcom-udpecho_ will 
+attempt to determine the variant by examining the __TestRespSN__, 
+__TestRespRecvTimeStamp__, and __TestRespReplyTimeStamp__ fields of the
+UDPEchoPlus packet for non-zero values.
 
 Example usage (RFC 862 compliant):
 
-      $ akcom-udpecho -c 5 udpecho.example.com 30006
+      $ akcom-udpecho -c 5 --rfc udpecho.example.com 30006
