Good virtualenv and packaging tutorials for beginner?

[Leam Hall]

Folks on IRC have suggested using virtualenv to test code under 
different python versions. Sadly, I've not found a virtualenv tutorial I 
understand. Anyone have a link to a good one?

The next step will be to figure out how to package a project; a good 
tutorial URL would be appreciated on that, too.

Thanks!
