CPAN (http://www.cpan.org) is the Comprehensive Perl Archive Network; a large collection of Perl software and documentation.
I have contributed a number of Perl software packages to CPAN:
- RRD::Simple, Util::SelfDestruct, Parse::DMIDecode, Tie::TinyURL, Apache2::AutoIndex::XSLT, WWW::FleXtel, Sys::Filesystem
A comprehensive listing of all my CPAN releases can be found at http://backpan.perl.org/authors/id/N/NI/NICOLAW/ and http://search.cpan.org/~nicolaw/.
librrd-simple-perl, libparse-dmidecode-perl and libsys-filesystem-perl are available as standard packages in Debian and RedHat Linux distributions.
