title: in express how to specify option for prefix plugin for less?
body: <p><a href="https://github.com/less/less-plugin-autoprefix" rel="nofollow">https://github.com/less/less-plugin-autoprefix</a></p>
  
  <p>this is the plugin that i could use </p>
  
  <pre><code>var LessPluginAutoPrefix = require('less-plugin-autoprefix'),
      autoprefixPlugin = new LessPluginAutoPrefix({browsers: ["last 2 versions"]});
  less.render(lessString, { plugins: [autoprefixPlugin] })
  </code></pre>
  
  <p>However, In Express... I use less like this <code>app.use(require('less-middleware')(path.join(__dirname, 'public')..</code></p>
  
  <p>so where can i put <code>plugins: [autoprefixPlugin]</code> part in express. I am new to less and express so I'm pretty lost. </p>
