Yes, tt would be great if the scripts could also be in the
org.mathpiper and don't require any change to the classpath. GeoGebra
is using dynamic loading of jar files and MathPiper will end up in
geogebra_cas.jar (replacing Yacas), so it would be the easiest for us
not having to deal with special classpath settings for MathPiper.
Thanks for your help with all this!
