This is a quick readme file for an early version of the topology generator,
running with the GAtech itm generator.

Getting the files and packages:
	- get the GT-ITM package for topology generation from GAtech:

	directly from:
	http://www.cc.gatech.edu/fac/Ellen.Zegura/graphs.html
	then go to 'Software' and click on GT-ITM,

	or go thru the vint web pages:
	http://www-mash.cs.berkeley.edu/ns/ns-topogen.html

	- get the conversion program 'sgb2ns' from
	http://www-mash.cs.berkeley.edu/ns/ns-topogen.html
	go to 'Conversion of GT-ITM output to ns-2 format

	- add itm and sgb2ns to your path

	- get files topo-gen.tcl, topo-view.tcl, topo-gen-script.tcl
		topo-gen.tcl: provides an API for the topology generator
		topo-view.tcl: to view the topology using nam after generation
				and before actual simulation
		topo-gen-script.tcl: an example of using the functions provided 
			by the above 2 files

you're ready to go... ! run topo-gen-script.tcl and view the output 
topologies [nam may not do a good job in viewing large and complex 
topologies... see what you think !].

If you want more help on how to use the 'topology' proc in topo-gen.tcl, run 
ns, source topo-gen.tcl, then type 'topology -h' and follow instructions.
