README

This is a fork of binarydist

It is not comptabile with bsdiff, and uses snappy for compression of patches instead of bzip2.

Functions

func Diff

func Diff(old, new io.Reader, patch io.Writer) error

Diff computes the difference between old and new, according to the bsdiff algorithm, and writes the result to patch.

func Patch

func Patch(old io.ReadSeeker, new io.Writer, patch io.Reader) error

Patch applies patch to old, according to the bspatch algorithm, and writes the result to new.
