NAME
bsdiff
- generate a patch between two binary files
SYNOPSIS
oldfile newfile patchfile
DESCRIPTION
The
utility
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 average a factor of five smaller
than those produced by any other binary patch tool known
to the author.
The
utility
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
