+tcptrace is a TCP connection analysis tool. It can tell you detailed
+information about TCP connections by sifting through dump files.
+The dump file formats supported are:
+   Standard tcpdump format (you need the pcap library)
+   Sun's snoop format
+   Macintosh Etherpeek format
+   HP/NetMetrix protocol analysis format
+   NS simulator output format
+   NetScout
+   NLANR Tsh Format
+
+To see the graphs, you'll also need Tim Shepard's xplot program,
+available at http://www.xplot.org
