 If you have problems, simply modify the make file as needed. Contact me, if major problems
 arise.
 
+In order to utilize this program effectively you will also need Tcptrace, which you can download

+"Useful Companion Programs" (Note! This is not the xplot that is in the Ubuntu repositories).

 For typical usage, you probably just want -s.
 
+Once you run dccp2tcp, you will then want to run tcptrace on the tcp_file to generate graphs. The command should be something like this:
+tcptrace -lGt tcp_file
+
+You can then use xplot to view the resulting graphs, like this:
+xplot a2b_tsg.xpl a2b_rtt.xpl

 This program does have several important limitations:
-       1)Supports only a single DCCP contection per capture.
+       1)Supports only a single DCCP connection per capture.
        2)Source Port can't equal Destination Port. If the two are equal, this program will get very confused.
        3)DCCP MUST use 48 bit sequence numbers.
        4)Checksums are not computed (they are zeroed).
        5)Only converts those packet types used by the Linux implementation at this date
        6)DCCP Ack packets show up as TCP packets containing one byte
-       7)Very little error checking of packet headers, it's research software afterall
