+data channels---files, pipes, devices, sockets, etc.  It can create
+\"listening\" sockets, named pipes, and pseudo terminals.
+
+socat can be used, for instance, as TCP port forwarder, as a shell interface
+to UNIX sockets, IPv6 relay, for redirecting TCP oriented programs to a serial
+line, to logically connect serial lines on different computers, or to
+establish a relatively secure environment (su and chroot) for running client
+or server shell scripts with network connections. ")
