Here is a better diff. It also includes a "flowd-reader -L" mode that can 
be used to convert old flow logs to the new format. E.g.

flowd-reader -Lo new.log old.log

FYI, one very nice side effect of the new format is, because it has no 
per-log header, it makes logging to FIFO's and pipes much easier - no 
patches or special modes should be required now.

The next release of flowd will probably add the ability to log to multiple
targets, including Unix domain sockets. E.g. you could put the following 
in flowd.conf:

logfile "/var/log/netflow.log"
logfile "/var/run/stats.sock" socket datagram

and have a real-time summary process listening on /var/run/stats.sock 
accepting the flows.

But the first priority now is updating the Perl and Python code...
