I would suspect THAT would be a major source of potential corruptions.
There are commercial tools to do that, but it could get costly.

I learnt the hard way. DOCUMENT EVERYTHING ;)
If you are happy to field the calls from sites where an update has
failed, then I think you may be able to do something, but we like to
test everything before passing it to a customer. Have all those
'specials' now become part of the later versions, or will they have to
be new 'special' versions of the later code?
