"""Presentation object is a container for special automatic operations performing
animation of characters and other sprites that commonly are moved in game action.
The game creator must only write one of those .cbp (cheeseboys presentation) file in the right
format, and the Presentation object will move the actors on the scene.
Of course, Presentation are played on a real GameLevel instance.
NBB: the .cbp file format is (for now, but maybe it will never change) a simple list of python commands
using Cheese Boys APIs.
This will lead to security issues! If you write a python command that will erase your HD in a .cbp file
this will be executed by the game!
