%description
    GRZip II is a high-performance file compressor based on
    Burrows-Wheeler Transform (BWT), Schindler Transform (ST),
    Move-To-Front (MTF) and Weighted Frequency Counting (WFC). It uses
    The Block-Sorting Lossless Data Compression Algorithm (BSLDCA),
    which has received considerable attention over recent years for
    both its simplicity and effectiveness. This implementation has
    compression rate of 2.234bps on the Calgary Corpus (14 files)
    without preprocessing filters.
