python-based simulation package, Documentation and examples

 SimPy is a process-based discrete-event simulation language based on
 standard Python.
 .
 It provides the modeller with components of a simulation model.
 These include processes, for active components like customers, messages,
 and vehicles, and resources, for passive components that form limited
 capacity congestion points like servers, checkout counters, and tunnels.
 It also provides monitor variables to aid in gathering statistics.
 SimPy comes with extensive plotting capabilities.
