Thanks for sharing this issue on the list! I think scripting is a very
powerful tool for many GIS users.

I miss very much documentation, manual, tutorials and/or examples for this
topic. Time ago, I tried to use it, but I gave up shortly thereafter
because my lack of knowledge about it.

Maybe a short post in the blog can be very very useful to start working...
:-)

Volunteers?

Regards,
