-o TCP-options-file
              This  will  cause nemesis-dns to use the specified TCP-options-file as the options when
              building the TCP header for the injected packet.  TCP options can be up to 40 bytes  in
              length.   The TCP options file must be created manually based upon the desired options.
              TCP options can also be read from stdin by specifying '-o -' instead of a  TCP-options-
              file.
