Do you want help running the code? If the problems are Perl related, ( e.g. getting the required modules ) then you can search for nodes that can help you and post a question once you have more specific problems and accompanying error messages, system details etc...

If you want an explanation of the code you pointed to, then that is a hell of a lot to ask of volunteers! Maybe you should offer some kind of bribe. Or contact the SciGen people for a manual etc...

If you want to get into CFG, then maybe the example you gave isn't a good place to start, especially if you are unfamiliar with Perl, maybe start with some of the examples given in Tie::Cfg? But you may run into the same problems with not knowing enough Perl, so i would follow marto's advice and buff up a bit. Maybe working through a cfg related task, if you want to give it some personal interest?
