##adds action=logout
global $HandleActions;
SDV($HandleActions['logout'], 'HandleLogout');
function HandleLogout($pagename) {
        session_start();
        session_unset();
        if (isset($_COOKIE[session_name()])) {
                setcookie(session_name(), '', time() - 42000, '/');
                                }
        if (isset($_COOKIE['author'])) {
                setcookie('author', '', time() - 42000, '/');
                                }
        session_destroy();
  Redirect('Main.Logout');
}

I modified this code snippet from Dominique Faure, I think, adding the
unsetting of author cookie
