Welcome to the Ruby Enterprise Edition installer
This installer will help you install Ruby Enterprise Edition 1.8.7-2011.03.
Don't worry, none of your system files will be touched if you don't want them
to, so there is no risk that things will screw up.

You can expect this from the installation process:

  1. Ruby Enterprise Edition will be compiled and optimized for speed for this
     system.
  2. Ruby on Rails will be installed for Ruby Enterprise Edition.
  3. You will learn how to tell Phusion Passenger to use Ruby Enterprise
     Edition instead of regular Ruby.
