%description
    GNU zip (gzip) is a compression utility designed to be a replacement
    for the traditional Unix utility compress(1). Its main advantages
    over compress(1) are much better compression and freedom from
    patented algorithms. gzip produces files with a .gz extension.
    gunzip can decompress files created by gzip, compress and pack. The
    detection of the input format is automatic. The format of the .gz
    files generated by gzip is described in RFCs (Request For Comments)
    1951 and 1952.
