Search / Replace Script, Little Update

I would like a slight alteration of this script

I would like to be able to do this:

swap.pl swap.cfg  c:/reports  

and have it go through c:/reports and do in place search / replace in the files

Here is a sample swap.cfg   search for Replacewith


.report.html .report.pl

or if someone could explain how the config file works below that would be cool too.
