Anything related to Jupiter is in SVN or on the Google Code site. I
uploaded all of what I had from Jupiter's creator and I didn't see any
development document. If you need help you can try and ask some of the
people in this group who have modified the code base for their own
uses. The project is an Eclipse plugin project so you should just be
able to open it in Eclipse and run it like any other project.
I'm sorry I cannot provide any in depth help right now. I'm hoping
maybe others can try to help you answer your questions.
