A simple backend that reads translations from YAML files and stores them in an in-memory hash. Relies on the Base backend.

The implementation is provided by a Implementation module allowing to easily extend Simple backend‘s behavior by including modules. E.g.:

module I18n::Backend::Pluralization

  def pluralize(*args)
    # extended pluralization logic
    super
  end

end

I18n::Backend::Simple.send(:include, I18n::Backend::Pluralization)
