I have been doing a fair amount of packaging lately. I have also been testing Hardy Heron and performing system upgrades/fresh installations. Every time I perform one of these fresh installs I lose my packaging/build environment. Attempting to remember, off the top of my head, which packages to install to reinstate my packaging/build environment causes severe brain pain; so, for future reference I decided to record the process and create a wiki page. By following the instructions on the wiki page I should be able to get my packaging/build environment up and running within minutes.

On the subject of packaging, I really need to try and get more involved with packaging for Ubuntu.
