    # Gemfile should only have the gemspec directive.
    # An exception is when you need to develop against a gem that hasn't yet been released,
    # in this case you can declare that dependency in the Gemfile:
    #
    #   gem 'rack', github: 'rack/rack'
    #
    # gemspec is the place to declare dependencies.
