The Comprehensive Perl Archive Network (CPAN) is a software repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors.[1] CPAN can denote either the archive network or the Perl program that acts as an interface to the network and as an automated software installer (somewhat like a package manager). Most software on CPAN is free and open source software.[2]
Most, though not all, modules on CPAN are licensed under the GNU General Public License (GPL) or the Artistic license...
