Ouch, sorry for writing in German ... was not my intention to answer@all :(
>> There is also a way to interface Fricas with MMAs via SageMath, which has interfaces to Maple, Matlab, Magma, and Mathematica. Yes, I know and that's why it wasn't worthwhile to follow up this Rubi affair. I thought once it might be easy (though conversion to CL is) to translate, however, there are too many side conditions in the rules ...
