title: How to add production mode to sailsjs app when started using PM2
body: <p>To start sailsjs in production mode you append <code>--prod</code>.</p>
  
  <p>Run:
  <code>node app.js --prod</code></p>
  
  <p>I'm using PM2 and a simple json file for settings, which contains name of process and scriptname, to kick off the node process.</p>
  
  <p>How would I pass the production argument using PM2?</p>
