Ask HN: Who has experience with debian packaging?

Hey Everyone, I maintain a debian/ubuntu application (www.trimage.org) that I would like to have included in the Debian repositories. It's been really hard to find information on the correct way to package an application, contact the right debian maintainers and finding a sponsor via mentors.debian.net (debian works in a way that as an application maintainer, you add your application to mentors.debian.net and then find a sponsor to upload your application into debian repositories; my application: http://mentors.debian.net/cgi-bin/sponsor-pkglist?action=details;package=trimage). There are probably some people here on HN that have already gone through this process and have their applications in Debian. Can you give me (and others) tips on how to approach this? Cheers, Kilian
