R71: Can't re-use code that you've written before?

I haven't seen any discussion on this one yet (please correct me if I missed it). The way I read this you are not allowed to reuse code that you've written for past competitions without "customizing" it. I'm not entirely clear what is meant by "customized" in this rule, but our team's initial impression was that this meant that it would have to be re-typed to be usable. Is that how others interpret it?
