      url  = require('url'),
      sys  = require('sys'),
      express = require('express'),
      http=require('http');
  
  var app = express();
  var server = http.createServer(app);
  var socket = io.listen(server);
  
  app.engine('.html', require('ejs').__express);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'html');
  
  app.get('/', function(req, res){
      res.render('home');
  });
  
  app.listen(4000);
  sys.puts('server running ' + 'now ' + Date.now());
