title: Assetic - How to disable asset combination?
body: <p>I am using assetic to manage my CSS files in the Symfony 2 framework. It works well in production mode.</p>
  
  <p>My problem is that in debug mode, assetic keeps combining my files into one output file. It makes it difficult to track a particular CSS style. Plus the combined file is not always updated.</p>
  
  <p>How can I disable this feature in debug mode ?</p>
  
  <p><strong>Edit</strong>: Here is my call to assetic:</p>
  
  <pre><code> {% stylesheets filter='lessphp,cssrewrite'
      '@DevoptionBaseBundle/Resources/less/front.less'
      '@DevoptionBaseBundle/Resources/less/back.less'
      '@DevoptionBaseBundle/Resources/public/css/custom-theme/jquery-ui-1.10.0.custom.css'
      '@DevoptionBaseBundle/Resources/public/css/jquery.mCustomScrollbar.css'
      output='css/style2.css' 
      %}
  </code></pre>
