 * That line should go just before the closing body tag.
 *
 * Omniupdate will dynamically replace this tag with a link, wrapped
 * around a 1px transparent gif. The line of code containing the link is
 * customizable in Setup > Web Sites. This script dynamically replaces
 * our copyright link's href with the href that OU inserts for us.
