+      ngrep strives to provide most of GNU grep's common features, applying
+      them to the network layer. ngrep is a pcap-aware tool that will allow you
+      to specify extended regular or hexadecimal expressions 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 and snoop.
