You say you are 'trying' to run this, are we to believe you've encountered some sort of problem? If so you are going to have to tell us what the problems are (see How do I post a question effectively?). If you want to learn more about Perl see:

• http://learn.perl.org
• http://perldoc.perl.org
• The Tutorials section of this site.

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?
