BSPATCH(1)		FreeBSD	General	Commands Manual		    BSPATCH(1)

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 dra-
     matic loss	of performance.

SEE ALSO
     bsdiff(1)

AUTHORS
     Colin Percival <cperciva@FreeBSD.org>

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	was built.
