 *
 * This module reports uptime information about your bot to http://uptime.eggheads.org. The
 * purpose for this is to see how your bot rates against many others (including EnergyMechs
 * and Eggdrops) -- It is a fun little project, jointly run by Eggheads.org and EnergyMech.net.
 *
 * If you don't like being a part of it please just unload this module.
 *
 * Also for bot developers feel free to modify this code to make it a part of your bot and
 * e-mail webmaster@eggheads.org for more information on registering your bot type. See how
 * your bot's stability rates against ours and ours against yours <g>.
