Chapter 15. Perl Modules
There is a lot more to Perl than what we're able to show you in this book, and there are a lot of people doing a lot of interesting things with Perl. If there is a problem to solve, then somebody has probably already solved it and made their solution available on the Comprehensive Perl Archive Network (CPAN), which is a worldwide collection of servers and mirrors containing thousands of modules of reusable Perl code.
If you want to learn how to write modules, consult the Alpaca book. In this chapter, we'll show you how to use modules that already exist.
