     * 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.
