Show me how to set up CRON

I've got a script that I need to run on my server every monday at midnight. I've tried to figure out how to do this, but it's a little over my head. The script I need to run is already in my cgi-bin, and I have confirmation that I have CRONTAB privileges on my server. (Running Linux & Apache.) All I need to do is get it running and for you to give me EXACT instructions on how you did it, so that I can repeat if necessary. (When I say EXACT instructions, that's what I mean. In other words, you'll need to pretend you're explaining it to a six year old!) ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
