Similarly here. The point I was trying to make was that neither of these are exactly baked into the OS. The system that runs on the actual computer is a standalone thing, independant of what the user sees. They can all be replaced. > Now, get a life and stop reading these computer nets all the time, or > you'll turn into a computer geek! > -- Jon > -- > Jonathan Krueger > If you see this article being operated in an unsafe manner, call > ...uunet!daitc!jkrueger jkrueger@daitc.arpa (703) 998-4777 Ha!
