2.13 Using Perl modules
Perl modules provide a range of features to help you avoid reinventing the wheel, and can be downloaded from CPAN ( http://www.cpan.org/ ). A number of popular modules are included with the Perl distribution itself.
Categories of modules range from text manipulation to network protocols to database integration to graphics. A categorized list of modules is also available from CPAN.
To learn how to install modules you download from CPAN, read "Installing CPAN Modules" (perlmodinstall) in the Perl Library Reference Manual (Volume 6).
To learn how to use a particular module, use
Typically you will want to
use Module::Name, which will then give
you access to exported functions or an OO interface to the module.
"Frequently asked questions about Perl" (perlfaq) in the Perl FAQ contains questions and answers related to many common tasks, and often provides suggestions for good CPAN modules to use.
"Perl modules (packages and symbol tables)" (perlmod) in the Perl Library Reference Manual (Volume 2) describes Perl modules in general. "Writing new modules and finding existing ones" (perlmodlib) in the Perl Library Reference Manual (Volume 2) lists the modules which came with your Perl installation.
If you feel the urge to write Perl modules, "Preparing a new module for distribution" (perlnewmod) in the Perl Library Reference Manual (Volume 6) will give you good advice.
