It's great having python support natively included in GPGME. I've been reviewing the gpg support in other languages, and ruby's support for GnuPG is limited and not well-synced with upstream GnuPG development.
If GPGME could natively produce a ruby module, that would be great! I think swig is supposed to be able to do that, but i don't know swig well enough to make it happen myself right now. So this is a request for that feature.
