	// This script will keep wow addons up to date.
	//
	// You need to edit the $config['wowdir'] variable, and add the required
	// "addAddon()" lines under the "Addons to keep up to date" heading.
	//============================================================================
	// Changes:
	//======================================
	// 04/01/2008 - Added Ability to store addAddon lines in a separate file
	//              rather than having to edit this file every time there is an
	//              update.
	//======================================
	// 24/12/2008 - Added GroupCalendar
	//======================================
	// 17/12/2008 - Added DoTimer
	//            - Added Recount
	//            - Added DeadlyBossMods
	//            - Added Ripped
	//======================================
	// 14/12/2008 - Added Enhanced Flight Map Official download location
	//            - Added EasySerum
	//            - Added X-DF-Date header.
	//======================================
	// 28/11/2008 - Fixed issue where sometimes toc files were corrupted causing
	//              wow to show the addon as incomatible
	//            - Lower the timout when trying to find the remote version
	//            - Dont show nasty PHP error if remote server returned nothing
	//======================================
	// 18/11/2008 - Added Support for "Manual" type downloads (just shows a
	//              message after the rest have downloaded)
	//            - Added Auctioneer to example list (beta and normal)
	//            - Added QuestHelper to example list
	//            - Fixes for adding X-DF-Version to stop it sometimes being added
	//              twice, or blank.
	//            - Fixed WOWUI support
	//            - Added force-update config option (downloadall)
	//===================
	// 15/10/2008 - Updated for Curse url Changes
	//            - Started keeping a record of changes
