NAME
bspatch - apply a patch built with bsdiff(1)
SYNOPSIS
bspatch oldfile newfile patchfile
DESCRIPTION
The bspatch utility generates newfile from oldfile and patchfile where
patchfile is a binary patch built by bsdiff(1).
The bspatch utility 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.

BUGS
The bspatch utility does not verify that oldfile is the correct source
file for patchfile. Attempting to apply a patch to the wrong file will
usually produce garbage; consequently it is strongly recommended that
users of bspatch verify that oldfile matches the source file from which
patchfile was built, by comparing cryptographic hashes, for example.
Users may also wish to verify after running bspatch that newfile matches
the target file from which patchfile was built.
