Okay, here's an example of what I'd like:  for every snort alert,
don't just save (into mmdd at ...3818...) the packet that caused
the alert, but also save the ten preceeding and ten succeeding
packets between the same hosts.

This is why I am running tcpdump and snort simultaneously.  My
question remains.  Sorry, Jason, but your "RTFM" suggestion
to craft a clever snort rule doesn't help.  - Carl
