title: less-style markdown viewer for UNIX systems
body: <p>I have a Markdown string in JavaScript, and I'd like to display it (with bolding, etc) in a <code>less</code> (or, I suppose, <code>more</code>)-style viewer for the command line.</p>
  
  <p>For example, with a string </p>
  
  <pre><code>"hello\n" + 
  "_____\n" + 
  "*world*!"
  </code></pre>
  
  <p>I would like to have output pop up with scrollable content that looks like</p>
  
  <blockquote>
    <h2>hello</h2>
    
    <p><em>world</em></p>
  </blockquote>
  
  <p>Is this possible, and if so how?</p>
