	"nonstandard": false,    // Define non-standard but widely adopted globals such as escape and unescape.
	"prototypejs": false,    // Enable globals exposed by Prototype JavaScript framework.
	"rhino": false,    // Enable globals available when your code is running inside of the Rhino runtime environment.
	"wsh": false,    // Enable globals available when your code is running as a script for the Windows Script Host.

	// == JSLint Legacy ===================================================

	// == Undocumented Options ============================================
	//
	// While I've found these options in [example1][2] and [example2][3]
	// they are not described in the [JSHint Options documentation][4].

	// [4]: http://www.jshint.com/options/

	"maxerr": 100,      // Maximum errors before stopping.
	"predef": [         // Extra globals.
		//"exampleVar",
