Hmm ... the list manager apparently stripped the MIME attachment.
Here it is again inline.

Unix pipelines, on the other hand, tend to be used in a manner that is
strictly linear, without the fan-out and fan-in capabilities described

Morrison-style "network" from Unix processes and pipes, though it's
hard to see how that would work without something like `select`, which
didn't yet exist in 1978. Regardless, Unix still doesn't expose a
particularly convenient syntax for expressing these sorts of
constructions at the shell.
Rick Troth has recently published xfl, which is pretty much CMS Pipelines
for Unix.

He's got a slide deck on it at

There are a lot of really cool things you can do with fanin/fanout.
