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

'specials' now become part of the later versions, or will they have to
be new 'special' versions of the later code?
