title: grunt: how to replace paths in html file using grunt task
body: <p>inside my grunt configuration if have a variable which defines a directory which contains a css file. Now I would like to configure a grunt task which insert the value of this variable into a html file.
  For example, I can imagine that I have an index.html file as follows</p>
  
  <pre><code>&lt;!doctype html&gt;
     &lt;head&gt;
        &lt;link rel="stylesheet" href="&lt;% pathToCss %&gt;/styles.css"&gt;
        ...
  </code></pre>
  
  <p>But I cannot find a task which can do that for me. Any suggestions which grunt taks can do this for me ?</p>
