=for developers

If you're a developer, Makefile.PL will pack `cpanm` from
script/cpanm.PL and then copy that file to `bin/cpanm`.

You can pretend to be an author by running it with:

  perl Makefile.PL --author

You should install local::lib, Parse::CPAN::Meta, Module::Metadata,
App::FatPacker and HTTP::Tiny before doing so.

Do not commit the changes to `cpanm` standalone executable. We only
commit changes to this file whenever we tag a new CPAN release.
