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
     average 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.
