title: Remove a specific tag and replace it with awk
body: <p>I'm using a tool to generate some html that looks something like this:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;Blah&lt;/title&gt;
  &lt;style&gt;
  /* stuff */
  &lt;/style&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>But I'd like a way to replace that style tag with some custom styling</p>
  
  <pre><code>&lt;link rel="stylesheet" href="style.css"&gt;
  </code></pre>
  
  <p>possibly with <code>awk</code> or <code>sed</code> so that I can add it to my Makefile.
  Is this possible?</p>
