%description
    ngrep(1) strives to provide most of the grep(1) common features,
    applying them to the network layer. ngrep(1) is a PCAP-aware tool
    that will allow you to specify extended regular or hexadecimal
    expressions (based on PCRE) to match against data payloads of
    packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP
    and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null
    interfaces, and understands BPF filter logic in the same fashion as
    more common packet sniffing tools such as tcpdump(1).
