description = "Zstandard real-time compression algorithm";
longDescription = ''
Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression
ratio. Zstd can also offer stronger compression ratio at the cost of
compression speed. Speed/ratio trade-off is configurable by small
increment, to fit different situations. Note however that decompression
speed is preserved and remain roughly the same at all settings, a
property shared by most LZ compression algorithms, such as zlib.
