CVS update

[Marco Spinetti]

Hi all, in 10 days I will have to do a demo of cocoon2. I'm not expert of CVS and then my problem is this: I have cocoon2.0 and I know that now there is cocoon2-1. I would like to do the demo with the new version of cocoon2. How can I update my version without loose all my data? Can you explain me all the steps?   Thanks   Marco
