One of the requirements for this course is that you use SOME sort of version control when you manage your project. After several students asked "ok, what does that mean" and I said "well, you should use CVS" and they said "ok, what does THAT mean" we finally managed to get CVS installed on student.cs.uni.edu which is a machine to which you should all have access.
So, how do you use CVS??? Well there turn out to be a lot of good tutorials on CVS located on the web (type "CVS tutorial" in google)
You also can look at some notes from Sessions 24-26 in Dr. Wallingford's
notes from the last time he taught agile software systems.
