bspatch - apply a patch built with bsdiff(1)
bspatch generates <newfile> from <oldfile> and <patchfile> where <patchfile> is a binary patch built by bsdiff(1).
bspatch uses memory equal to the size of <oldfile> plus the size of <newfile>, but can tolerate a very small working set without a dramatic loss of performance.
