+	 * PHP.updateDNS

+	 *

+	 * +====================================================+

+	 *  Services Supported:

+	 *    - DynDns (dyndns.org)

+	 *    - DHSDns (dhs.org)

+	 *    - No-IP (no-ip.com)

+	 *    - EasyDNS (easydns.com)

+	 * +----------------------------------------------------+

+	 *  Requirements:

+	 *    - PHP version 4.0.2 or higher with CURL Library

+	 * +----------------------------------------------------+

+	 *  Public Functions

+	 *    - updatedns()

+	 *

+	 *  Private Functions

+	 *    - _update()

+	 *    - _checkStatus()

+	 *    - _error()

+	 *    - _detectChange()

+	 * +----------------------------------------------------+

+	 *  Changelog

+	 *    - 12 July 05, DynDNS, DHS, No-IP working. At this

+	 *        point I have to assume that EasyDNS works due

+	 *        to the fact that I don't have an account with

+	 *        them. I followed their Dynamic DNS docs. There

+	 *        is no error checking for CURL events at this

+	 *        point, error checking will be added soon.

+	 *

+	 *    - 11 July 05, Initial Build of updateDNS

+	 * +----------------------------------------------------+

+	 *  DynDNS   - Last Tested: 12 July 2005

+	 *  No-IP    - Last Tested: 12 July 2005

+	 *  HN.org   - Last Tested: 12 July 2005

+	 *  EasyDNS  - Last Tested: NEVER

+	 *  DHS      - Last Tested: 12 July 2005

+	 *  ZoneEdit - Last Tested: NEVER

+	 *  Dyns     - Last Tested: NEVER
