(description "Zstandard (@command{zstd}) is a lossless compression algorithm
that combines very fast operation with a compression ratio comparable to that of
zlib. In most scenarios, both compression and decompression can be performed in
‘real time’. The compressor can be configured to provide the most suitable
trade-off between compression ratio and speed, without affecting decompression
speed.")

(description "Parallel Zstandard (PZstandard or @command{pzstd}) is a
multi-threaded implementation of the @uref{http://zstd.net/, Zstandard
compression algorithm}. It is fully compatible with the original Zstandard file
format and command-line interface, and can be used as a drop-in replacement.
Compression is distributed over multiple processor cores to improve performance,
as is the decompression of data compressed in this manner. Data compressed by
other implementations will only be decompressed by two threads: one performing
the actual decompression, the other input and output.")
