title: MVC 3 Razor Meta Description / Keywords
body: <p>What is the simplest way of getting meta description / keywords onto my _Layout page?
  Something similar to how you get the page Title would be nice.  Such as</p>
  
  <pre><code>&lt;title&gt;@ViewBag.Title&lt;/title&gt;
  &lt;meta name="keywords" content='@ViewBag.Keywords'/&gt;
  &lt;meta name="description" content='@ViewBag.Description'/&gt;
  </code></pre>
  
  <p>My view would look something like:</p>
  
  <pre><code>@{
      ViewBag.Title = "Contact Me";
      ViewBag.Keywords = "My, keyword, list, etc";
  }
  </code></pre>
