NAME
     bsdiff -- generate	a patch	between	two binary files

SYNOPSIS
     bsdiff <oldfile> <newfile>	<patchfile>

DESCRIPTION
     bsdiff compares <oldfile> to <newfile> and	writes to <patchfile> a	binary
     patch suitable for	use by bspatch(1).  When <oldfile> and <newfile> are
     two versions of an	executable program, the	patches	produced are on	aver-
     age a factor of five smaller than those produced by any other binary
     patch tool	known to the author.

     bsdiff uses memory	equal to 17 times the size of <oldfile>, and requires
     an	absolute minimum working set size of 8 times the size of oldfile.
