title: What is the new Symfony 3 directory structure?
body: <p>I just created a new Symfony 2.5 project with a regular composer command:</p>
  
  <pre><code>php composer.phar create-project symfony/framework-standard-edition path/ 2.5.0
  </code></pre>
  
  <p>The Terminal asks me:</p>
  
  <blockquote>
    <p>Would you like to use Symfony 3 directory structure?</p>
  </blockquote>
  
  <p>What is this <em>Symfony 3 directory structure?</em> I have never seen it before... Is it new since 2.5?</p>
  
  <p>What are the benefits to using it?</p>
  
  <p>Is there any way to replicate this directory structure?</p>
