Sorry just forgot that this mailing list is not only python related.

Hmm I need a way to destroy all instances which where created via python. Perhaps there is a better way than recreating the interpreter. A "new" command like in the good old basic days would be perfect. But I couldn't find anything like this in the python docu. BTW I'm working on Virtual Reality Editor with a scripting interface. In the beginning I used swig but than I found boost. A really impressive peace of software!
