title: How set/get environment specific variable in a Yeoman Ember app
body: <p>Considering an Yeoman Ember app.</p>
  
  <p>I've looked different tools like:</p>
  
  <ul>
  <li><a href="https://github.com/logankoester/grunt-environment" rel="nofollow">https://github.com/logankoester/grunt-environment</a></li>
  <li><a href="https://github.com/jsoverson/grunt-env" rel="nofollow">https://github.com/jsoverson/grunt-env</a></li>
  <li><a href="https://github.com/outaTiME/grunt-config" rel="nofollow">https://github.com/outaTiME/grunt-config</a></li>
  </ul>
  
  <p>But I don't quite see how can you set/get for instance different adapter url in your router.js depending on some grunt/node environment.</p>
