[ns] changing the .cc files in aodv

[umair shah]

hey if i want to change the C++ files in ns2 where should i write make and make 
clean etc.I mean how I recompile it so that changes take place and work .and 
also tell me how can i revert back the changes so that if anything goes wrong I 
can go back to previous state.
for eg If I want to change something from aodv.cc file ,at which directory I 
should write make .?cd ns2.34/tcl  etc etc /aodv / here ? or ns2 34/ here ?
