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