Thanks Reiner. I was just about to broadcast this fix. I apologise to all
who are not running W2K though. I really was under the impression this would
work universally (no, I didn't test it

To all those who can't run it: Trust me, it's no great loss! It was a nifty
idea to start with but has since become totally sloppy & confusing.

> I am using it right now

In that case, *not* a dismal failure after all.
Jeff, you've made my day.

Have a look at a little thingy called depends (or any dependency walker for
that matter).

It does all this and much, much more

Actually - this program is totally AWESOME !!

I am using it right now to nail some developers who DIDN'T document some
.dll's that they are using in one of their programs, and I got them dead to
rights !!
