  #   # Because error messages were defined within Ecto, we must

  #   # Ecto will pass the :count keyword if the error message is
  #   # meant to be pluralized.
  #   # On your own code and templates, depending on whether you
  #   # need the message to be pluralized or not, this could be
  #   # written simply as:
  #   #
  #   #     dngettext "errors", "1 file", "%{count} files", count
