-go-lz4
-======
-
-go-lz4 is port of LZ4 lossless compression algorithm to Go. The original C code
-is located at:
-
-https://github.com/Cyan4973/lz4
-
-Status
-------
-[![Build Status](https://secure.travis-ci.org/bkaradzic/go-lz4.png)](http://travis-ci.org/bkaradzic/go-lz4)  
-[![GoDoc](https://godoc.org/github.com/bkaradzic/go-lz4?status.png)](https://godoc.org/github.com/bkaradzic/go-lz4)
-
-Usage
------
-
-    go get github.com/bkaradzic/go-lz4
-
-    import "github.com/bkaradzic/go-lz4"
-
-The package name is `lz4`
-
-Notes
------
-
-* go-lz4 saves a uint32 with the original uncompressed length at the beginning
-  of the encoded buffer.  They may get in the way of interoperability with
-  other implementations.
