  # Spans are not really compatible with bounding boxes because they break
  # the nesting chain and also may position text outside of the bounding box
  # boundaries, but sometimes you may wish to use them anyway for convenience
  # Here's an example of how to do that dynamically.

    text "Here's some default bounding box text. " * 10 
    span(bounds.width, 
      :position => bounds.absolute_left - margin_box.absolute_left) do
      text "The rain in spain falls mainly on the plains. " * 300
