(So you could do a build of slightly self-modifying code, a lot like the Linux build in 2.4 was, against a read-only tree.) Would this be a good tool for that sort of application? (There's all sorts of other "trial run" type applications; running stuff against database snapshots and then seeing what the deltas are, etc...) Rob
