-\fBlz4\fR is an extremely fast lossless compression algorithm. It is based on
-the \fBLZ77\fR family of compression scheme. At the compression speed of 400
-MB/s per core, \fBlz4\fR is also scalable with multi-core CPUs. It features
-an extremely fast decoder, with speed in multiple GB/s per core, typically
