Well, do you really need to use PAR? I am asking the question because you say that you are new to Perl and, maybe, you think that this is a standard way of using Perl. It isn't. The usual way is to use standalone Perl programs, using the perl my_prog.pl command under most systems, the shebang line under Unix and extension configuration under Windows. There are cases where you want to use PAR, but it is not the most common way of doing things.
