    (description
     "socat is a relay for bidirectional data transfer between two independent
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. ")

messaging middle-ware products.  0MQ sockets provide an abstraction of
asynchronous message queues, multiple messaging patterns, message
filtering (subscriptions), seamless access to multiple transport protocols and
more.")
