title: Customize Twitter Bootstrap with less in symfony2
body: <p>I've to solve a basic issue. The website has multiple sections and each of them uses an own colortheme. So want to change the .less varibles depending on which page the user visits.</p>
  
  <p>For example (pseudo code):</p>
  
  <pre><code>If request.get('_route') == 'section1'
      @primary-color: red;
  </code></pre>
  
  <p>I'm asking google for a while, but I can not get it work. I can use the less compiler under symfony, but I cannot override variables and I do not know how to inject logic/values form outside into less. Maybe someone can help me out with a simple example where to put what?</p>
