The Comprehensive Perl Archive Network (CPAN) is a 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.CPAN can denote either the archive network itself, or the Perl program that acts as an interface to the network and as an automated software installer (somewhat like a package manager).When searching a Perl module, sooner or later you will end up on one of two sites sites providing information about CPAN modules.Both Meta CPAN, and org will show you a link to download the module, but in most cases that's not what you need.PL Data-Dumper-2.121/MANIFEST Data-Dumper-2.121/Data-Dumper-2.121/Todo Data-Dumper-2.121/Changes Removing previously used /home/NAME/.cpan/build/Data-Dumper-2.121 CPAN.pm: Going to build I/IL/ILYAM/Data-Dumper-2.121gz Checking if your kit is complete...

Depending on the Operating System and which Perl distribution you have, the specific instructions differ.CPAN has no revision control system, although the source for the modules is often stored on Git Hub.Also, the complete history of the CPAN and all its modules is available as the Git PAN project, allowing to easily see the complete history for all the modules and for easy maintenance of forks.You might also notice a search box for org which we find appropriate, a list of recently uploaded modules on the homepage and a new page on how to mirror CPAN.If you read the latter page, you'll see that the master mirror is now org:: CPAN (rsync only).Sometimes a maintainer will be appointed to an abandoned module.They can release new versions of the module, and accept patches from the community to the module as their time permits. Old style of updates: update whole perl core package. New packages need the latest version, which makes the process of packaging perl modules slower and painful.Creating updates of modules in main perl package is complicated, sometimes almost impossible because of change in directories/paths inside of the main package. This process should help maintainability of core perl package. For updates has been developed Fedora:: App:: Maintainer Tools Usage: But, maintainertool can't handle unusual macros like: Name: perl-%.Most Perl modules are written in Perl, some use XS (they are written in C) so require a C compiler.Modules may have dependencies on other modules (almost always on CPAN) and cannot be installed without them (or without a specific version of them).
