Visual specification of actor configurations

An initial actor configuration is a set of actors with behaviours. A configuration is a concurrent system and this makes it far from trivial to specify it in a traditional actor language. We adapt the scenario technique in order to be able to specify actor behaviours. Using this technique called Actor Scenarios, a configuration is specified by visually specifying the causal ordering of events in the configuration for all external stimuli. We believe this is a good way of specifying an actor configuration because the overview over the configuration is greatly improved
