But I need some help from you: What are we supposed to do with this code? It's not self-contained. Can you provide a self-contained, reproducing, example, on a branch of a public version control system (which I hope you are using for everybody's sake, else see http://perl-begin.org/tutorials/bad-elements/ ), with instructions on what exactly should we run? Otherwise, your instructions will remain unclear.
