-----------

    XZ Utils provide a general-purpose data-compression library plus
    command-line tools. The native file format is the .xz format, but
    also the legacy .lzma format is supported. The .xz format supports
    multiple compression algorithms, which are called "filters" in the
    context of XZ Utils. The primary filter is currently LZMA2. With
    typical files, XZ Utils create about 30 % smaller files than gzip.

    To ease adapting support for the .xz format into existing applications
    and scripts, the API of liblzma is somewhat similar to the API of the
    popular zlib library. For the same reason, the command-line tool xz
    has a command-line s
