  <p>
    <b>An example with a basic event handler.</b> Here we've tied
    several form values together with a simple event handler invocation.
    The result is that the form values are updated in real-time as
    the selection is changed using Jcrop's <em>onChange</em> handler.
  </p>

  <p>
    That's how easily Jcrop can be integrated into a traditional web form!
