+ (description
+ "Plzip is a massively parallel (multi-threaded) lossless data compressor
+and decompressor that uses the lzip file format (.lz). Files produced by plzip
+are fully compatible with lzip and can be rescued with lziprecover.
+On multiprocessor machines, plzip can compress and decompress large files much
+faster than lzip, at the cost of a slightly reduced compression ratio (0.4% to
+2%). The number of usable threads is limited by file size: on files of only a
+few MiB, plzip is no faster than lzip.
+Files that were compressed with regular lzip will also not be decompressed
+faster by plzip, unless the @code{-b} option was used: lzip usually produces
+single-member files which can't be decompressed in parallel.")
