// Note that all ns-3 attributes (not just the ones exposed in the below
// script) can be changed at command line; see the ns-3 documentation.
//
// 
// The source node and sink node can be changed like this:
// 
// ./waf --run "scratch/myManet --sourceNode=20 --sinkNode=10"
//
// This script can also be helpful to put the Wifi layer into verbose
// logging mode; this command will turn on all wifi logging:
// 
// ./waf --run "scratch/myManet --verbose=1"
//
// By default, trace file writing is off-- to enable it, try:
// ./waf --run "scratch/myManet --tracing=1"
//
// When you are done tracing, you will notice many pcap trace files 
// in your directory.  If you have tcpdump installed, you can try this:
//
// tcpdump -r scratch/myManet-0-0.pcap -nn -tt
