Man am I happy, I'm going to use this. Man ratrace for info.
Thanks to Russ for the original code review on the 9vx version and many improvements. Thanks to Noah Evans for writing the first version of ratrace user-mode tool. Thanks to Jim McKie for the substantial improvements in the current version, which made it portable. Thanks to Geoff for getting it all in. I've found it very handy for figuring things out, I hope you can use it too. ron
