Oh, quite true.  Wherever I wrote "CVS", instead substitude "whatever
revision control the system is under".  But then you have to make sure
your merging tool knows what that is, how to access it...   heck, maybe
how to access MULTIPLE ones!  What if The System (tm) is in CVS, but you
locally mirror it into Subversion or something?  This could snowball
really fast.

I think it'd have to be the latter.  The former doesn't give us too much
gain over what we already have (it gives some, of course, since the
merger can know "it's been modified", but if we're gonna bite this
bullet, we might as well bite all the way through at once).

And before anybody else says it, what we REALLY want is a versioning
filesystem!  Yeah!  And files like this should have a vendor branch where
the 'upgrades' go!

Every time you look at the durn thing, the problem gets bigger   8-}
