Hi guys, at first, thank you very much for a great DNS library, it helped me a lot recently! Next, as I need DNSSEC signing features, and as far as I know there's no dnssec implementation in python, I've written it myself. Now I've merged it with the git version of dnspython's dnssec module. I am attaching the patch and a short example of usage. I would like to ask, if it would be possible to merge this features to upstream dnspython? Does it make sense for you? Regards, Tomas Mazak
