Hmmm, it appears someone (you :) has actually already added some explanatory text to installation.txt giving some explicit instructions on what to do.

I've essentially cut and pasted them into the success message in demo.py for those who don't read documentation.

Richard seems to have given me CVS access so I've committed that change and am closing this Request. I'm sure someone will let me know if I've done something horribly wrong :)
