Trace/Loss

Hi,  

Does anyone know where I can find the code for Trace/Loss ?  I have
the following code in my script:

#create error model
 set em [new ErrorModel]   
 $em set rate_ 0.02

set tr [$ns create-trace Loss $f $n0 $n1]
$em drop-target $tr

It runs, and marks all the dropped packets with an "e" in file "f".  
What I don't understand is, it looks like create-trace creates a
Trace/Loss object, but I cannot find this object.

Also, I don't really understand what $em drop-target $tr does.

Thanks for any help!!
