title: Symfony 2.1 own vendor library
body: <p>I want to put some code that I shall use in different projects outside the app's bundles. I put it in a new folder in the vendor folder but I can't included in the project. Which are the steps?</p>
  
  <ul>
  <li>Should I follow a special structure of folder and namespaces</li>
  <li>How do I included in my project.</li>
  </ul>
  
  <p>On Google I found a lot of ambiguous answers. I tried also <a href="https://stackoverflow.com/questions/11496255/where-to-register-autoload-when-the-vendor-is-not-managed-with-composer-in-symfo">this</a> but it did not work.</p>
