Emacs, some love it, some hate it, and once in a while I stumble on something I wish I'd found years ago. I thought I'd share some of the packages I use, partly so I don't forget!

• debian-el contains a major mode for editing sources.list, as well as an interface to apt for the truly emacs centric. Also has useful support for bug reporting and bug numbers...
• emacs-goodies-el lots of toys, and of particular interest and use to me, a major mode for apache configuration files and color-theme which is somewhat self explanatory
