title: How does Play!'s Comet support work?
body: <p>I saw the Akka module's description says that <a href="http://playframework.org" rel="noreferrer">Play</a> has great Comet support, but I've never used <a href="http://en.wikipedia.org/wiki/Comet_%28programming%29" rel="noreferrer">Comet</a> before and I can't find any mention of it in Play's documentation.  How does it work in Play?</p>

  <p>I spent a few hours over two days figuring this out so I wanted to share this info for other Play beginners.</p>
