Python is a free, publicly-developed language, not a commercial product. This means you can quickly and easily do grove-based processing from Python. This is very cool. To use the following sample program all you need to do is download the base Python package and the win32com package, both available for free from the Python.org site. Follow their installation instructions.
Returns grove root node.
When using the Pythonwin window, you can use the Python object browser to explore the grove visually. I think you'll find it encouragingly easy to use, with lots of potential. Jade does not provide any form of API or facilities for interacting with the rest of the system. Note that this combination does not provide all the functions that commercial tools like Omnimark and Balize provide, although it does do a lot of things you might otherwise need those sorts of tools for. This might be very interesting too, although I haven't tried it myself.
