title: Laravel display a custom message in Maintenance Mode
body: <p>I'm checking out Laravel docs for Maintenance Mode: </p>
  
  <p><a href="https://laravel.com/docs/5.3/configuration#maintenance-mode" rel="noreferrer">https://laravel.com/docs/5.3/configuration#maintenance-mode</a></p>
  
  <p>When you execute the command <code>php artisan down</code>, it will put the application under maintenance mode, and return the 503.blade.php view.</p>
  
  <p>Works good, but there is an option I can't really make work.. when I do:</p>
  
  <pre><code>php artisan down --message='Upgrading Database' --retry=60
  </code></pre>
  
  <p>I want to display the message in the view, I tried accessing the obvious choice with <code>{{ $message }}</code> without success, returns undefined variable.</p>
  
  <p>My question is: how to access it?</p>
