+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.")
