Not Good. While I'm not arguing that CTM *is* the best solution, after a very long and thoughtful Jordan had a *LONG* time ago (patchkit days), I don't think it's possible to build a 'simple' system which can get around the above problem. The amount of complexity required to build a system which can detect problems such as this is beyond the scope of this project, IMHO. (But, someone feel free to prove me wrong. *grin*) Basically, I think anyone capable of modifying their own local sources are capable of hand applying patches, in either CTM deltas or diff form.
