Extended Perl5 Tutorial
Now that you've been introduced to the new features in Perl5, you're ready to embark on an extended tutorial on references and modules. You need to understand how these elements work so that you can make use of the examples to follow in this book. There's a lot to cover here, so grab a cup of coffee, and I'll try to avoid monotony. You might find it helpful to be sitting at your computer with your copy of Perl5 ready to run so that you can try out the sample code as you go along.
