  Thank you for installing #{gem.summary}!

  This version of rspec-rails only works with versions of rails >= 3.0.0.beta.4.

  To configure your app to use rspec-rails, add a declaration to your Gemfile.
  If you are using Bundler's grouping feature in your Gemfile, be sure to include
  rspec-rails in the :development group as well as the :test group so that you
  can access its generators and rake tasks.

    group :development, :test do
      gem "rspec-rails", ">= #{RSpec::Rails::Version::STRING}"
    end

  Be sure to run the following command in each of your Rails apps if you're
  upgrading:

    script/rails generate rspec:install

  Even if you've run it before, this ensures that you have the latest updates
  to spec/spec_helper.rb and any other support files.

  Previous versions of rspec-rails-2.0.0.beta installed files that are no
  longer being used, so please remove these files if you have them:

    lib/tasks/rspec.rake
    config/initializers/rspec_generator.rb

  Lastly, be sure to look at Upgrade.markdown to see what might have changed
  since the last release.
