[ns] How to use two version of NS2?

[Guy Israeli]

Hi all,

I would like to use two version of NS2, and old version and a new version.
I know how to install 1 version of ns.
what i would like to do is, for instance to call each ns version like this
in terminal/bash

> ns-old example.tcl

and for the new

>ns-new example.tcl

thus running example.tcl on two differrent version of ns

how do I change the ns calling name so i can use whatever calling name
that i want?

thanks a lot,

Guy
