Description:
    Skein (<http://www.skein-hash.info/>) is a family of fast
    secure cryptographic hash functions designed by Niels
    Ferguson, Stefan Lucks, Bruce Schneier, Doug Whiting, Mihir
    Bellare, Tadayoshi Kohno, Jon Callas and Jesse Walker.
    .
    This package uses bindings to the optimized C implementation
    of Skein.  We provide a high-level interface (see module
    "Crypto.Skein") to some of the Skein use cases.  We also
    provide a low-level interface (see module
    "Crypto.Skein.Internal") should you need to use Skein in a
    different way.
    .
    Currently we have support for Skein as cryptographic hash
    function as Skein as a message authentication code
    (Skein-MAC).  For examples of how to use this package, see
    "Crypto.Skein" module documentation.

Flag reference
    Description: Use the reference implementation instead of the optimized one.
    Default: False

Flag force-endianness
    Description: Use a manually selected endian when compiling (see flag 'big-endian').
    Default: False

Flag big-endian
    Description: When manually selecting the endianness, use big-endian (default is little-endian).
    Default: False
