(description "LZ4 is a lossless compression algorithm, providing
compression speed at 400 MB/s per core (0.16 Bytes/cycle). It also features an
extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle).
A high compression derivative, called LZ4_HC, is also provided. It trades CPU
time for compression ratio.")
