    <p>Using this library will automatically set Carmen to use Rails' built-in I18n functionality. This means that changing some configuration should be done through Rails and not Carmen. For example, adding paths for additional locale files should be done inside config/application.rb:</p>

  <pre><code>config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
