Unfortunately, I've unexpectedly had to move house, so I haven't been able to get time to adding scripting support. I had hoped to get to it before now, but I haven't. I'm leaving the country in three days for a month, and I won't have access to a compiler. I'll be unsubscribing from this mailing list after I send this message. I hope that when I get back, my life will settle down a little and I'll be able to hack on Inkscape some more. Sorry for dropping the ball here.
