+Displays the contents of a TCP or UDP stream between two nodes.  The data
+sent by the second node is prefixed with a tab to differentiate it from the
+data sent by the first node.
+
+I<prot> specifies the transport protocol.  It can be one of:
+  B<tcp>   TCP
+  B<udp>   UDP
+
+I<mode> specifies the output mode.  It can be one of:
+  B<ascii> ASCII output with dots for non-printable characters
+  B<hex>   Hexadecimal and ASCII data with offsets
+  B<raw>   Hexadecimal data
+
+Since the output in B<ascii> mode may contain newlines, the length of each section
+of output plus a newline precedes each section of output.
+
+I<filter> specifies the stream to be displayed.  UDP streams are selected with
+IP address plus port pairs.  TCP streams are selected with either the stream
+index or IP address plus port pairs.  For example:
+  B<ip-addr0>:B<port0>,B<ip-addr1>:B<port1>
+  B<tcp-stream-index>
+
+I<range> optionally specifies which "chunks" of the stream should be displayed.
+
+Example: B<-z "follow,tcp,hex,1"> will display the contents of the first TCP
+stream in "hex" format.
