title: How to add a config.js file into nwjs install directory?
body: <p>I use node-webkit-builder to package my nwjs application.
  Since the program running directory path is not same as the install directory path( the running directory path is like this: C:\Users[username]\AppData\Local\Temp\nw7388_7201 ). I don't know how to add my config.js file in the install directory, and read it in my nwjs app.</p>
  
  <p>Best regards.</p>
