Turns asynchronous function into synchronous

var flow    = require('control-flow')
var fs      = require('fs')
var express = require('express')

flow.sync(fs, 'readFile')

var app = express.createServer()
app.use(function(req, res, next){
  flow.fiber(next)
})

app.get('/', function(req, res){
  var data = yield(fs.readFile(__filename, 'utf8'))
  res.send(data, {'Content-Type': 'text/plain'})
})

app.listen(3000)
