	};

opt.set(['-h','--help'], function () {
		var help = opt.help(), ky;

				console.log("\t" + ky + "\t\t" + help[ky]);     
		}

}, "This help document.");
	
// Parse the command line options
if (process.argv.length < 3) {

}
console.log("\nConfig object properties set by opt: ");
console.log(util.inspect(config));
