NAME

     bsdiff — generate a patch between two binary files

SYNOPSIS

     bsdiffoldfile⟩ ⟨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.
