title: What does compilationOptions.emitEntryPoint mean?
body: <p>Just installed the rc1 tools and created a new web project to see what has changed in the template.</p>
  
  <p>I noticed that project.json now contains:</p>
  
  <pre><code>"compilationOptions": {
      "emitEntryPoint": true
  }
  </code></pre>
  
  <p>But it's unclear what this does.</p>
  
  <p>Does anyone have an idea?</p>
