DebugConsole

DebugConsole won't be ported to Dojo 0.9. Instead just set isDebug: true in your djConfig parameters and use console.log to print debugging messages, which will go to the Firebug console on FF, or a custom <div> on your page on other browsers.

<script type="text/javascript" src="../../dojo/dojo.js" 
	djConfig="parseOnLoad: true, isDebug: true"></script>
...
console.log("hello world");
