CPAN into devel/p5-Dist-Zilla.
Dist::Zilla builds distributions of code to be uploaded to the CPAN.
In this respect, it is like ExtUtils::MakeMaker, Module::Build, or
Module::Install. Unlike those tools, however, it is not also a system for
installing code that has been downloaded from the CPAN. Since it's only
run by authors, and is meant to be run on a repository checkout rather
than on published, released code, it can do much more than those tools,
and is free to make much more ludicrous demands in terms of prerequisites.
