I shouldn't have to ask this question, but I do. It's probably all in the documentation somewhere, but I'm a Debian newbie and I still can't find my way around properly.
I have just installed the stable debian release woody from CD-ROMs, my first experience with debian, and I have found it a success. I especially liked app-get and its friends. Now there's a package (twiki) in the testing distribution I'd like to install. It doesn't appear on the CDROMs, presumably because they are just the stable release. How do I go about it, so that it will be properly downloaded to the proper place, installed properly, and I retain a copy of the package in case I need to do it again? Do I need to set up my own patial mirror on my hard disk somewhere? -- hendrik
