	Original Site: "Countdown to Kickoff - Super Bowl XLI" at www.haroldinc.com in late January 2007
	History: I originally created a "Countodwn to Kickoff" page for Super Bowl XLI, which the
	Indianapolis Colst won on February 4th, 2007. This countdown/countup script was a natural
	progression.
	
	How to use this script:

	This script calculates the difference in time between right now and another point in time which
	we designate as theMainEvent. It returns the difference in time as either a countdown or
	countup timer.
	
		year - The year in which theMainEven happens
		month - The month in which theMainEvent happens
		day - The day in which theMainEvent happens
		hour - The hour in which theMainEvent happens
		minute - The minute in which theMainEvent happens
		ampm - Must be either 'am' or 'pm'

	This program is free software; you can redistribute it and/or modify
	it under the terms of the GNU General Public License as published by
	the Free Software Foundation; either version 3 of the License, or
