Package lz4 implements reading and writing lz4 compressed data (a frame), as
specified in
http://fastcompression.blogspot.com/2013/04/lz4-streaming-format-final.html.
This package is compatible with the LZ4 frame format although the block level
compression and decompression functions are exposed and are fully compatible
with the LZ4 block format definition, they are low level and should not be
used directly.
