The intro system script is a simple way to make intro's for your game.
see the script itself for more details.

e.g.

EvaluateSystemScript("intro.js");

function test_intro() {
  var intro = new Intro();

  intro.addText("Once upon a time...");
  intro.addText("There was a...");
  intro.addSpace(15);
  intro.addImage(LoadImage("warrior.png"));
  intro.addSpace(15);
  intro.addText("And so the quest begins!");

  intro.play();
}
