title: Using include in different situations
body: <p>I have a boilerplate that has various includes, one being:</p>
  
  <pre><code>    @include('nav')
  </code></pre>
  
  <p>I would like to use the same boilerplate for the CMS of my site, but use a different nav.</p>
  
  <p>What would be the best way of getting the boilerplate to include a different nav when the user is using the CMS:</p>
  
  <pre><code>    @include('nav-cms')
  </code></pre>
