The Comprehensive Perl Archive Network (CPAN) is a very useful collection of Perl code. However, authors of modules can delete older versions of modules to only let CPAN have the latest version of a module and BackPAN is where these deleted modules are backed up.
BackPAN.org is a project created by Wallace Reis using Web::Simple and HTML::Zoom. Kindly hosted by Shadowcat Systems. Website design developed by Paulo Vitor.
Please send any corrections, suggestions or comments to wreis at cpan.org.
You can check out the source code from: git://git.shadowcat.co.uk/catagits/BackPAN-Web.git
