Earlier today i was messing around with ubuntu and found a package that gave me a graphic box with different version in it like ubuntu xubuntu kubuntu and so on.
I found it very useful as you could install one and remove the other at the same time, But the main problem is now i can't seem to find it again and i've searched google but can't find a post about it either which sucks.

Does anyone know what this package is call and the terminal code to get it to run.
