+TTCP is a benchmarking tool for determining TCP and UDP performance
+between 2 systems.
+
+The program was created at the US Army Ballistics Research Lab (BRL)
+and is in the public domain. Feel free to distribute this program,
+but please do leave the credit notices in the source and man page intact.
+
+How to get TCP performance numbers:
+receiver: host1 $ ttcp -r -s
+sender: host2 $ ttcp -t -s host1
+
+The -n and -l options change the number and size of the buffers.
