Summary
In this chapter, you learned how to shake Perl to get information out of it. This includes not only how to use the perldoc command to find out about all the online documentation but also how to use CPAN to learn about modules and documentation stored in the main Perl archive.
By using modules and exploring the work of other people, you can make your programming job simpler. But you still have to do some programming yourself, so the next few chapters cover how to actually write Perl programs.
