[You've assigned this bug to bugs.debian.org, which is for bugs in our bug tracking system, not a general catch-all bug location.] -- Don Armstrong https://www.donarmstrong.com "You know," said Arthur, "it's at times like this, when I'm trapped in a Vogon airlock with a man from Betelgeuse, and about to die from asphyxiation in deep space that I really wish I'd listened to what my mother told me when I was young." "Why, what did she tell you?" "I don't know, I didn't listen." –- Douglas Adams _The Hitchhikers Guide To The Galaxy_
