Earlier today I received a couple of emails that pointed out an error I had in my code. In the CronJob class I have two initialize methods and Ruby does not allow methods to be overloaded. If you want to fix the error, replace the two initialize methods with the code below:

def initialize(minute="*", hour="*", day="*", month="*", 

    	weekday="*", command="*")

	@minute = minute

	@hour = hour

	@day = day

	@month = month

	@weekday = weekday

	@command = command

end
