Sample express app using smoosh config debug flag.

app.js

var express = require('express')
  , cluster = require('cluster')
  , fs = require('fs')
  , debug

var smooshConfig = JSON.parse(fs.readFileSync('./smoosh.json', 'UTF-8'))
// set the debug flag
debug = smooshConfig.DEBUG  
  
var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.set('views', __dirname + '/views');
