flowdumper and Full Flow Information
Although flowdumper is generally less useful than flow-print, it has some unique features. You've already used the summary feature (-s) to test Cflow.pm. (flowdumper can also accept Perl instructions on the command line, but if you're sufficiently skilled in Perl to do that, you can read the flowdumper manual page.)
If you don't use the summary feature, flowdumper prints all the information the flow file includes for every flow.
