This is a little program that can be used to create 'Patcher' style patches (for use by kpg, patch32lsb or KBpatcher programs) from the difference between two binary files.
It might be useful if you have patched an executable using
KBPatcher or
patch-nickel-css and want to create a patch that can be used with patch32lsb.
For example, patch32lsb can't currently handle zlib compressed strings (because I haven't worked out how to do that) but KBPatcher and patch-nickel-css can. You can use one of those programs to apply a patch to the compressed string, and then use makepatch to create a patch of the difference between the original and modified executable that is usable by patch32lsb.
