Understood.
It might be an extra level or two, but it's been working for ExtUtils::MakeMaker, even on Windows, at least as far back as 2002, and making use of the Makefile generated from a perl Makefile.PL is part of their design philosophy.
I know other similar tools make use of a ./Build.PL, but I haven't used that toolset, so don't know if that idiom has an intermediate step as well, or not.
Since I had some experience in automating README and similar tasks using MakeMaker for my few distros, I figured I'd share that knowledge.
