How about importing the scanned in source (in electronic form) back into
the States and doing a 'diff' there. This could produce an electronic
patchfile to repair the mistakes in the scanned in code, meaning that the
whole of the code could be cleaned up in one go. This patchfile could then
be exported as it holds no crypto source code. (Somehow this seems *too*
simple. Would this perhaps get up the US gubmint's nose? Have I missed some
nuance or implicit limitation?)
