[ns] ns-trace file information

[Aja Rangaswamy <eng81522@nus.edu.sg>]

Hi,

This is regarding the information found in the ns trace files for the 
wireless models using the new trace format.

When i run the simple-wireless.tcl(Marc Greiss Tutorial), i get a trace file

of about 20,000 lines.
When i parse the file to get the sent, received and dropped packets, 
(based on 'r', 's' and 'D' fields), i get numbers of about 6000 each.

Surely, not that many packets are being sent or received.

So how do i extract information such as the acutal number of packets being 
sent or received.

I really appreciate you help.
