This chapter presented the format of a Perl module. We discussed the Exporter module, the @ISA array, and the ability of a module to export symbols. After building the rudiments of a Complex module, we compared our work with a real module, Roman.pm. Then we showed how to download any module using the Perl Package Manager. Finally, we discussed the CPAN repositories of Perl modules and how you can use CPAN to download any of the modules located there.
