title: Load JavaScript on demand
body: <p>I am using jQuery and jQuery mobile.</p>
  
  <p>I think both libraries got downloaded to my iPhone over ATT's internet, which is slow.</p>
  
  <p>So I am wondering if there is some framework taking care of it and trimming the file to necessary size for functions I use in the page?</p>
  
  <p>Is there also something for CSS file, which can be fat also?</p>
  
  <p>Thanks</p>
