  The multiway rendezvous introduced in Theoretical CSP is a powerful paradigm
to achieve synchronization and communication among a group of (possibly more
than two) processes. We illustrate the advantages of this paradigm on the
production cell benchmark, a model of a real metal processing plant, for which
we propose a compositional software controller, which is written in LNT and
LOTOS, and makes intensive use of the multiway rendezvous.
