Questions tagged [perl-module]

A Perl module is a reusable portion of Perl code.

In Perl, modules are vital to object-oriented design and can provide static variables referenced similarly to those in C++. The package model improves code organization, by allowing the coder to import functions from external files and 'bless' new object instances. Further, perl allows the directory structure holding modules to aid in the description of an object hierarchy. Perl module files traditionally have the extension '.pm'

see perlmod - perldoc.perl.org for more information.
