/**


 * An applet wrapper for Presentations. To display a presentation in


 * an HTML page you need to put use following applet tag:


 * <pre>


 *	&lt;applet code=marimba.gui.PlayerApplet width=300 height=200&gt;


 *	&ltparam name=presentation value=example.gui&gt


 *	&lt/applet&gt


 * </pre>


 * In addtion to that you need to make sure that the marimba classes


 * are accessible to the applet. Note that scripting does not work


 * inside most browsers.
