%X This paper presents a software tool for visualising and
   reasoning about the behaviour of message\-passing concurrent
   programs built with the CSO library for the Scala
   programming language. It describes the models needed to
   represent the construction of process networks and the
   runtime behaviour of the resulting program. We detail the
   manner in which information is extracted from the use of
   concurrency primitives in order to maintain these models and
   how these models are diagrammed. Our implementation of
   dynamic deadlock detection is explained. The tool
   can produce a sequence diagram of process communications,
   the communication network depicting the pairs of processes
   which share a communication channel, and the trees resulting
   from the composition of processes. Furthermore, it allows
   for behavioural specifications to be defined and then
   checked at runtime, and guarantees to detect the illegal
   usage of concurrency primitives that could otherwise lead to
   deadlock or data loss. Our implementation imposes only a
   small overhead on the program under inspection.
