def description # :nodoc:
  <<-EOS
The exefy command replaces the default gem batch(.bat) script runner with
a Windows executable(.exe) stub. Exefy also includes hooks that will
automatically do this for all new Gem installs and will remove the
executable with a Gem uninstall.

Requires a RubyInstaller Ruby installation and the RubyInstaller DevKit.
