<!-- 1. Simple, usual case with callback -->
<script type="text/javascript">
	Glow("2").load("core", "widgets").ready(function (glow) {
		// core & widgets loaded & dom ready
		glow.widgets.doodle();
	});
</script>

<!-- 2. 'Application Pattern'. Allows glow instance to be easily used in a wider but not global scope -->
<script type="text/javascript">
	(function() {
		var glow = new Glow("2.3").load("core", "widgets").ready(init);

		function init() {
			// core & widgets loaded & dom ready
			glow.widgets.doodle();
		}
	})();
</script>

<!-- 3. User sets global in callback -->
<script type="text/javascript">
	(function() {
		Glow("2.3.4").load("core", "widgets").ready(function (G) {
			// core & widgets loaded & dom ready
			window.glow = G;
			init();
		});
	})();

	function init() {
		glow.widgets.doodle();
	}
</script>

<!-- 4. Callback for glow modules loading -->
<script type="text/javascript">
	Glow("2.3.4").load("core", "widgets").loaded(function (glow) {
		// core & widgets loaded but dom may not be ready
	});
</script>

<!-- 5. Callback is always required, due to asynchronous loading -->
<script type="text/javascript">
	// can't detect missing callback here
	var glow = new Glow("2.3.4").load("core", "widgets");

	// fails because modules not done downloading yet.
	glow.widgets.doodle();
</script>

<!-- 6. Documentation is different -->
<script type="text/javascript">
	/**
		@name Glow#widgets.doodle
	 */
	// ...
</script>
