Пакет gem-setup: Информация

Every well practiced Rubyist is aware of Minero Aoki's ever setup.rb script.
It's how most of us used to install our Ruby programs before RubyGems came
along. And it's still mighty useful in certain scenarios, not the least of
which is the job of the distro package maintainer.

Ruby Setup converts setup.rb into a stand-alone application. No longer
requiring the distribution of the setup.rb script with every Ruby package.
Just instruct one's users to install Ruby Setup (gem install setup) and go from
there. As long as a project is setup.rb compliant, as most are, then there is
little to nothing it's developer must do.
