Thanks for this Rick;

the link to http://vl.fmnet.info/csp/ labelled "The CSP Archive" (at
the bottom of the page) is broken and should probably be removed. I
notice that, in general, there's a bit about CSP the calculus, but
little if anything about CSP the programming style or common idioms
that might attract practitioners. A more comprehensive entry would
probably need to be split over several pages and include code examples
and advantages over a variety of forms of concurrency, such as STM,
event-driven awfulness, and so on.

Sorry I don't have time to be more helpful!
