Ahh, I suppose it would have to be that way. I assume it keeps some
meta-information around for this purpose?

I've seen such dev systems before. ObjectMaster basically did this,
although it was largely faked out back onto files, which I think is the
"right" solution.

process, and yet vendors simply don't DO this in their products.
