on the client side's HTML HEAD tag you include:

  <script src="/dictionary.js" type="text/javascript" charset="utf-8"></script>
  <script>
    var current_language = "italian";  
  </script>

you manage current_language variable according to user's langauge

and where translated text is needed you use the amazing <dictkey> tag:

class Node
  attr_accessor :children
  attr_accessor :title

  def general_deep_copy
    Marshal.load(Marshal.dump(self))
  end

  def specific_deep_copy
    Node.new(@title,children.map(&:specific_deep_copy))
