Introduction

System Requirements

This book assumes you have a computer at your disposal with Perl installed. If not, 

then you can still read the book, but you won't be able to try the examples. Many of 

the examples assume you're working on a UNIX system, Perl's  home court.  Where 

possible, I've noted differences under Microsoft Windows, but if you're using any 

thing more exotic, you may need to make minor adjustments to get the examples 

to work.

Perl Version

This book was written using Perl version 5.6.1. If you're using a newer version, you 

may find that the examples given need small adjustments. If you're using an older 

version, you should consider upgrading to get the most out of this book (and Perl).
