 * Here's a sample main() function that you can add to your applet class:
 *
 *  public static void main(String args[])                 
 *  {
 *     AppletFrame.startApplet( <ClassName>, "Application Title");
 *  }
 *
 * The class AppletFrame provides a simple AWT Frame window for running
 * applications.
