title: LESS is not working in Express Js
body: <p>I'm trying to use less with express js</p>
  
  <pre><code>var app = express.createServer();
  var pub = __dirname + '/styles';
  app.configure(function(){
      app.set("view engine", "html");
      app.register(".html", require("jqtpl").express);
      app.set('views', __dirname + '/views');
      app.set("view options", { layout: true });
  
      app.use(express.compiler({ src:pub, enable: ['less'] }));
      app.use("/styles", express.static(pub));
      app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
      app.use(express.bodyParser());
      app.use(app.router);
  });
  </code></pre>
  
  <p>in layout.html</p>
  
  <pre><code>&lt;!DOCTYPE HTML&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;${title}&lt;/title&gt;
          &lt;link rel="stylesheet" href="/styles/style.less" type="text/css" media="screen" title="main css" charset="utf-8"&gt;
      &lt;head&gt;
      &lt;body&gt;
              &lt;h1&gt;Hello World!&lt;/h1&gt;
          {{html body}}
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>My style.less is </p>
  
  <pre><code>@color: #4D926F;
  h1 {
      color:@color;
  }
  </code></pre>
  
  <p>I can call <a href="http://localhost/styles/style.less" rel="nofollow">http://localhost/styles/style.less</a> but it is not render CSS.</p>
