deja-packet transmits raw packets through a
specified interface. In pcap file mode,
deja-packet transmits user-selected packets from a
libpcap capture file (such as one created by
Ethereal/Wireshark or tcpdump). In raw file mode,
deja-packet transmits the raw contents of a file
as one whole packet, and will exit immediately
after the attempted transmission is complete
(allowing deja-packet to be easily used in a
script).
