 tcpflow is a program that captures data transmitted as part of TCP
-connections (flows), and stores it in a way that is convenient for
-protocol analysis or debugging.  A program like 'tcpdump' only shows a
-summary of packets seen on the wire, but usually doesn't store the
-data that's actually being transmitted.  In contrast, tcpflow
-reconstructs the actual data streams and stores each flow in a
-separate file for later analysis.
+connections (flows), and stores the data in a way that is convenient
+for protocol analysis and debugging.  Each TCP flow is stored in its
+own file. Thus, the typical TCP flow will be stored in two files, one
+for each direction. tcpflow can also process stored 'tcpdump' packet
+flows.
 
-tcpflow understands sequence numbers and will correctly reconstruct
-data streams regardless of retransmissions or out-of-order delivery.
-However, it currently does not understand IP fragments; flows
-containing IP fragments will not be recorded properly.
-
-Note: this port includes a small patch that adds the capability of
-      reading the packets from a tcpdump(1) capture file, using
-      a new option (-r).
