	// the preferred way to load the dojo firebug console is by setting has("dojo-firebug") true in dojoConfig
	// the isDebug config switch is for backcompat and will work fine in sync loading mode; it works in
	// async mode too, but there's no guarantee when the module is loaded; therefore, if you need a firebug
	// console guaranteed at a particular spot in an app, either set config.has["dojo-firebug"] true before
	// loading dojo.js or explicitly include dojo/_firebug/firebug in a dependency list.
