It lets you structure your app a little differently, app.js:
require('fsjs')(8000,'user','repo',function(data,defaultCallback){
defaultCallback('<!doctype html>'+data)
})
exports.get = function(file,callback) {
console.log(this.request.url)
// '/arpith/fsjs/edit/README.md'
callback('the file edited is '+file)
}
