description = "Extremely fast compression algorithm";
longDescription = ''
Very fast lossless compression algorithm, providing compression speed
at 400 MB/s per core, with near-linear scalability for multi-threaded
applications. It also features an extremely fast decoder, with speed in
multiple GB/s per core, typically reaching RAM speed limits on
multi-core systems.
