Generate UUIDs with uuidgen from Node

uuid.js

var sys = require("sys");
var events = require('events')
var childProcess = require('child_process');

var Uuid = function() {
	var self = this;
	
	this.generate = function() {
		var child = childProcess.exec(
			'uuidgen | tr [:upper:] [:lower:]',
			function(error, stdout, stderr) {
				self.emit('generate', stdout.match(/[\w-]+/));

				if(error !== null) { console.log(error); }
			}
		);
	}
};
sys.inherits(Uuid, events.EventEmitter)

module.exports = Uuid;

// // Example
// 
// var sys = require('sys');
// 
// var Uuid = require("./libs/uuid");
// 
// var uuid = new Uuid();
// 
// uuid.on('generate', function(data) {
