I would definitely like to read that. Could you post a link to it, here or
elsewhere? I thought I had various links to your povr stuff, but can't find
them. (They might be on my previous Win 7 machine, which is down at the moment.)
I actually couldn't find any povr/Github reference on the web at all, even with
a detailed Google search(!)
