    Edit your Gemfile (do not forget to run 'bundle install' after doing that)
    Some of the following commands assume that you passed the --binstubs option
    to bundle install. If you haven't done so, use 'bundle exec rake' where the
    examples below use './bin/rake'
    ---------------------------------------------------------------------------
    If you want to use rspec for testing, you first need to uncomment the line
    that declares it in the Gemfile. The you need to run 'bundle install' again
    Once that's done, you need to actually install it into your app and update
    your spec_helper as shown in the dm-rails README
    ---------------------------------------------------------------------------
    Install rspec (optional):             rails g rspec:install
    Have a look at the dm-rails README:   http://github.com/datamapper/dm-rails
    ---------------------------------------------------------------------------
    Have a look at available rake tasks:  ./bin/rake -T
    Generate a simple scaffold:           rails g scaffold Person name:string
    Create, automigrate and seed the DB:  ./bin/rake db:setup
    Start the server:                     rails server
    ---------------------------------------------------------------------------
    After the sever booted, point your browser at http://localhost:3000/people

Why does the rails command include a gem install utility?

rails g rspec:install
