gitPAN

gitPAN lets you answer some simple questions about CPAN projects easily. For example, "give me version X of project Y" or "what changed between versions X and Y?". Surprisingly difficult to answer with just CPAN indexes, something search.cpan.org sort of provides, gitPAN makes easy.

Version control, and git in particular, is ideal for this. Its all about tracking versions of a project, and letting you ask questions.

gitPAN took the entire history of CPAN, every release ever, put each project into its own repository, and hosts them on github.com. Now, for example, if you want to know what changed between version 2.34 and 2.36 of XML::Parser...

git clone git://github.com/gitpan/XML-Parser
cd XML-Parser
git diff 2.34..2.36

You'll learn a bit about the difficulties building gitPAN, handy ways to use gitPAN to make maintaining CPAN installations easier, and how gitPAN makes patching CPAN modules simpler.
