    From powturbo@21:1/5 to All on Thu Jan 2 23:04:31 2020
    Turbo Range Coder : https://github.com/powturbo/Turbo-Range-Coder

    - Fastest Range Coder/Arithmetic Coder
    - 100% C (C++ headers).
    - OS/Arch: Linux amd/intel, arm, PowerPC, s390x, MacOs.
    Windows: Mingw, visual c++
    - No other Range Coder / Arithmetic Coder encode or decode faster with better compression
    - Up to 3 times faster than the next fastest range coder with similar compression ratio
    - Can work as bitwise or/and as multisymbol range coder
    - 32 or 64 bits range coder. Big+Little endian
    - Renormalization output 8,16 or 32 bits
    - Easy connection to bit, nibble or byte predictors
    - stdin/stdout file compressor included

    - NEW: simple single threaded bwt compression/decompression w/ QLFC + TurboRC

    - New: fast lzp byte preprocessor.
    Can be used to reduce (for speedup reason) the input length before further processing like bwt or RC.

    - New: improved bwt speed with lzp preprocessing.
    lzp is considered only when the reduction of the the input length is large enough (> ~6%)
    The minimum lzp match length (32-256) can be set with the option "-l#" (default = 96), -l0=No lzp
    (Use other text files than enwik8/9 for testing)

    - New: Faster Inverse bwt for large inputs
