What site can I use to generate a custom sources.list?

I've just installed Ubuntu 11.04, after installing 10.10 I found a real useful official site which compiles a /etc/apt/source.list that can be copied and pasted, and a list of the key commands for terminal. I don't seem to be able to find it now and the only others I can find are generic lists that others have made.


Solution 1:

The site in question is RepoGen.
