        This script encrypts another one with 256 Bit AES, "swordfish" (the
        marx one) as password and zero IV and outputs another script, which
        decrypts the containing cipher and runs the code.
        Disclaimer: This was written just for fun and may contain meaningless
        use of cryptography. If you can not stand it, send complains to
        henning on the honerable orgizm.net server.
