perlmodinstall - Installing CPAN Modules
You can think of a module as the fundamental unit of reusable Perl code; see perlmod for details. Whenever anyone creates a chunk of Perl code that they think will be useful to the world, they register as a Perl developer at https://www.cpan.org/modules/04pause.html so that they can then upload their code to the CPAN. The CPAN is the Comprehensive Perl Archive Network and can be accessed at https://www.cpan.org/ , and searched at https://metacpan.org/ .
This documentation is for people who want to download CPAN modules and install them on their own computer.
