Bundle::CPANxxl - Bundle with a few more components than Bundle::CPAN
IO::Tty -- if we are not explicit, we get a delay and YAML comes interactively
This bundle includes Bundle::CPAN plus what I consider indispensible but not everybody can compile, namely Expect and Module::Signature.
I've taken the liberty to also add YAML::Syck because of its speed advantage.
Kwalify verifies that the files in the prefs_dir/ directory are written according to the specs.
Last not least every full installation of CPAN needs the CPAN::Reporter. I put it into this xxl bundle because it may be a bit overkill for small installations. Maybe we will shift it over to Bundle::CPAN.
