Usage

usage: xor [-h] [-b buffer_limit_usize] [-l listen_address]
           [-m mtu_usize] [-o timeout_f64_secs]
           [-r remote_address] [-s set_method] [-t token_hex_u8]
Command Summary:
        -b              for total pre-allocated buffer
        -h              prints this help message
        -l              listen address
        -m              for link mtu
        -o              client timeout in seconds
        -r              remote address
        -s              one of: `xor`, `dnspad`, `dnsunpad`; defaults to `xor`
        -t              e.g. 0xFF
