        <h3>What does this do?</h3>
        <p>Prints the date and time the page was last modified.  If no format is given, it will default to a format similar to 'Jan 01, 2004'.</p>
        <h3>How do I use it?</h3>
        <p>Just insert the tag into your template/page like: <code>{modified_date format="%A %d-%b-%y %T %Z"}</code></p>
        <h3>What parameters does it take?</h3>
        <ul>
                <li><em>(optional)</em>format - Date/Time format using parameters from php's strftime function.  See <a href="http://php.net/strftime" target="_blank">here</a> for a parameter list and information.</li>
