[Moose-dev] MSE 3.0 to 2.1 Converter?

Hi everybody, last question for today :-) Is there a converter which converts from MSE 3.0 to 2.1 format? I'm obviously trying to visualize some Java code with Code City. The MSE was created using verveinej. I know that the inFamix paid version can produce MSE 2.1 output, but if somehow possible I would prefer an open source / non-paid solution. Maybe, is there an older version of verveinej available which would produce MSE 2.1? Or was verveinej producing MSE 3.0 from the beginning? Thanks a lot and best regards, Torben
