title: How does jQuery's noConflict function work?
body: <p>Hey, I was just looking at the docs for the noConflict function and it says nothing about how it works (obviously). I just wondered if anyone knew.</p>
  
  <p>Does it unset <code>$</code>? (<code>delete window.$</code>?)</p>
  
  <p>Any suggestions will be much appreciated.</p>
