Cool, I hoped you might say something like that :)

When you say trivial, are you including as "trivial" the integration of 
prolog code into the Java code base in Kepler, and working with the 
complex drag and drop mechanism that is implicit in Ptolemy?  Or do you 
mean, trivial in that we can generate an ASCII-art view of the tree in 
prolog?  I can see the latter being trivial if sparrow-tk already 
handles the use case, but not the former based on my knowledge of 
Kepler.  What are your the specific plans for how the sparrow-tk prolog 
code base will be called and integrated with our various Java-based
