So I've decided that I don't feel like waiting any longer for the wishlist bug for syslog output from dpkg to be implemented. I've written a little shell wrapper that will do this for me, and will make it available if anyone likes - I may send it here for cricitism regardless.
However, I realize that this is really not the right approach, it's just expedient. I'd be quite happy to patch dpkg (my needs are simple, so I don't think it'd be hard), but I don't want to bother unless I think it'll be integrated. So I'm writing this to find out how it should be written such that it'll be most likely to be incorporated. Thoughts, opinions, flames?
