    A Ruby gem implementing Threshold Secret Sharing. This code can be
    used in your Ruby applications or as a simple command line (CLI)
    executable for splitting and reconstructing secrets.

  spec.description = <<-EOF
    Threshold Secret Sharing (TSS) provides a way to generate N shares
    from a value, so that any M of those shares can be used to
    reconstruct the original value, but any M-1 shares provide no
    information about that value. This method can provide shared access
    control on key material and other secrets that must be strongly
    protected.

    This gem implements a Threshold Secret Sharing method based on
    polynomial interpolation in GF(256) and a format for the storage and
    transmission of shares.

    This implementation follows the specification in the document:
