    # In the .bos file there was what I thought was clever at the time but

    # a single event could be multiple scenes. But in reality it very rearly used
    # and creating scenes with in events created a potential user error situation.
    
    # So I want to get rid of all the EVENTS and read Scenes directly. Unless
    # the event is empty of scenes. In which case to create a scene with the
    # text of that event.

                       # it. It will be more like Blender's node editor's Frame.
    
    # Even tho I want to change radically the idea of events. We still need to
    # think in the events terms. Because we are parsing and old file. Funny how
    # I will need to write this thing twice. For both file-types.
