I'm guessing your aversion to bdiff is because your product is
commercial. If I remember my GPL correctly, just distributing and using
it alongside your commercial product would not require you to GPL your
commercial product as well. You are not creating a derivative or
incorporating bdiff into your product. But check with a lawyer on this
just to make sure.
Same for xdelta.
Anyone else have any pointers to products, source code, or an easy to
implement algorithm which can do this? (A non-GPLed Cocoa class would
be
*perfect*, BTW, not that I'm expecting one to be out there... <grin>)
diff and patch are part of Mac OS X. You can use 'diff -a --binary' to
create a patch file, and 'patch --binary original patchfile'. Haven't
tested this, but that's what the man pages indicate.
Hope this helps,
