-.Sh SYNOPSIS

-.Ao Ar oldfile Ac Ao Ar newfile Ac Ao Ar patchfile Ac
-.Sh DESCRIPTION
-.Nm
-compares
-.Ao Ar oldfile Ac
-to
-.Ao Ar newfile Ac
-and writes to
-.Ao Ar patchfile Ac
-a binary patch suitable for use by bspatch(1).
-When
-.Ao Ar oldfile Ac
-and
-.Ao Ar newfile Ac
-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.
-.Pp
-.Nm
-uses memory equal to 17 times the size of 
-.Ao Ar oldfile Ac ,
-and requires
-an absolute minimum working set size of 8 times the size of oldfile.
