[ns] processing trace files

[Aicho SAID(ENG)]

Thanks I did it and it works now, and I think they should update their website because it's quite
confusing. 

I have another question if anyone can help, I want to calculate end-to-end delay of the packets
sent , and I am using the new trace format of wireless simulations. 
I was thinking of extracting sent packet time from souce to destination and packet id but I am not
sure at which level at should look at is MAC or RTR?
And I have notice that some lines are like
s -t 1.006144333 -Hs 0 -Hd -2 what does this -2 mean? (i am using a  chain topology ans sending
packet from node 0 to node 1 and node 2 is out of range of node 0), so it shouldn't hear it.

Also packet are sent form node 0 to node 1 but I never seem to see packet receive -Hs 0 -Hd 1, it
is either r -t 1.00555 -Hs 0 -Hd -2 at MAC  or r -1.00222 -Hs 1 -Hd -2 at MAC or r -1.00222 -Hs 1
-Hd -1 at AGT so which one is the packet received at node 1.

Thanks in advance for any knid of input.
