+layer.  It's a PCAP-based tool that allows you to specify an extended regular
+or hexadecimal expression to match against data payloads of packets.  It
+understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6,
+IGMP and Raw, across a wide variety of interface types, and understands BPF
+filter logic in the same fashion as more common packet sniffing tools, such as
+tcpdump and snoop.")
