    /**
     * PLUGGING INTO USER PAGES
     * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     * Userpages are highly programmable and extendable using a number of
     * hooks. These hooks are:
     *
     *   - userpage_sidebar_left
     *   - userpage_sidebar_right
     *   - userpage_tabs_links
     *   - userpage_tabs_body
     *
     * You can add a variety of sections to user pages, including new tabs
     * and new sections on the tables. To add a tab, attach to
     * userpage_tabs_links and echo out:
     *
     *   <li><a href="#tab:YOURTABID">YOUR TAB TEXT</a></li>
     *
     * Then hook into userpage_tabs_body and echo out:
     *
     *   <div id="tab:YOURTABID">YOUR TAB CONTENT</div>
     *
     * The userpage javascript runtime will take care of everything else,
     * meaning transitions, click events, etc. Currently it's not possible
     * to add custom click events to tabs, but any DOM-related JS that needs
     * to run in your tab can be run onload and the effects will be seen when
     * your tab is clicked. YOURTABID should be lowercase alphanumeric and
     * have a short prefix so as to assure that it remains specific to your
     * plugin.
     *
     * To hook into the "profile" tab, use userpage_sidebar_{left,right}. Just
     * echo out table cells as normal. The table on the left (the wide one) has
     * four columns, and the one on the right has one column.
     * 
     * See plugins.php for a guide on creating and attaching to hooks.
