// scripts and/or other plugins which may not be closed properly.

		// undefined is used here as the undefined global variable in ECMAScript 3 is
		// mutable (ie. it can be changed by someone else). undefined isn't really being
		// passed in so we can ensure the value of it is truly undefined. In ES5, undefined

		// as this (slightly) quickens the resolution process and can be more efficiently
		// minified (especially when both are regularly referenced in your plugin).
