END OF LICENSE Implements SimPy Processes, resources, and the backbone simulation scheduling by coroutine calls. Based on generators (Python 2.2 and later) Change history: 4/8/2003: - Experimental introduction of synchronization of simulation time and real time (idea of Geoff Jarrad of CSIRO -- thanks, Geoff!). * Changes made to class __Evlist, _nextev(), simulate() Dec 11, 2003: - Updated to Simulation 1.4alpha API Dec 2003: Merged in Monitor and Histogram Feb 2004: Repaired bug in activeQ monitor of class Resource. Now actMon correctly records departures from activeQ. May 19, 2004: added missing Histogram class
