Together with a number of other early modelling tools, its architecture helped to inspire newer languages such as Modelica. It was recognised for its flexible use of variables and parameters, which it always treats as solvable, if desired The software remains as an active open-source software project, and has been part of the Google Summer of Code programme in 2009, 2010, 2011, 2012, 2013 (under the Python Software Foundation) and has been accepted for the 2015 programme as well.
