CPANs
CPANs, short for Comprehensive Perl Archive Network mirrors, refer to the worldwide network of servers that host and distribute Perl modules, distributions, and documentation. The CPAN serves as the primary repository used by developers to publish reusable code and by users to install and learn about Perl software. Each mirror maintains a local copy of the CPAN repository and is synchronized with other mirrors to keep content up to date.
CPANs are organized as a distributed system rather than a single central site. Mirrors reproduce the structure
Access to CPANs is typically via CPAN clients, such as the interactive CPAN shell (cpan) or the
Maintenance of CPANs is collaborative and volunteer-driven. Mirrors are operated by individuals, universities, companies, and organizations
