-Intro
------
-
-What's there to say? It's Space Invaders in JavaScript! Create the game, give it a 
-div to draw to, tell it when the keyboard is mashed and that's all you need to 
-add Space Invaders to a wesite.
-
-The Space Invaders Javascript code is all in one file - why is this? Well this is actually
-part of a series of experiments that are used as tutorials, and at this stage we're keeping
-things simple with single files.
-
-Adding Space Invaders to a Web Page
------------------------------------
-
-First, drop the spaceinvaders.js file into the website.
 
-Now add a canvas to the page.
-
-````HTML
-<canvas id="gameCanvas"></canvas>
-````
-
-Finally, add the Space Invaders game code. You create the game, 
-intialise it with the canvas, start it and make sure you tell
-it when a key is pressed or released. That's it!
-
-````HTML
-<script>
-//	Setup the canvas.
-var canvas = document.getElementById("gameCanvas");
-canvas.width = 800;
-canvas.height = 600;
-
-//	Create the game.
-var game = new Game();
-
-//	Initialise it with the game canvas.
-game.initialise(canvas);
-
-//	Start the game.
-game.start();
-
-//	Listen for keyboard events.
-var pressedKeys = [];
-window.addEventListener("keydown", function keydown(e) {
-	var keycode = window.event.keycode || e.which;
-    if(!pressedKeys[keycode])
-    	pressedKeys[keycode] = true;
-    //	Supress further processing of left/right/space (37/29/32)
-    if(keycode == 37 || keycode == 39 || keycode == 32) {
-    	e.preventDefault();
-    }
-    game.keyDown(keycode);
-});
-window.addEventListener("keyup", function keydown(e) {
-	var keycode = window.event.keycode || e.which;
-    if(pressedKeys[keycode])
-    	delete pressedKeys[keycode];
-    game.keyUp(keycode);
-});
-</script>
