bspatch man page
bspatch — apply a patch built with bsdiff(1)
|bspatch|| ⟨ |
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.
