This version appears fairly well documented, except that the TODO says "implement most of the functionality". What functionality is missing?
Having written code which examines distributions to extract information before, I understand the need for this module. There's not many tests on it, but I hope that it turns out to be portable (e.g. runs on Windows , Macs and various Nix flavors). I look forward to making use of it when (if?) I take up some old CPAN-related projects again.
