NAME¶

bspatch — apply a patch built with bsdiff(1)

SYNOPSIS¶

bspatch

⟨oldfile⟩ ⟨newfile⟩ ⟨patchfile⟩

DESCRIPTION¶

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.
