No no no. Follow the instructions in the INSTALL.txt. ../buildout -N
should only take
a very very brief time. I spent a lot of time making it so. All eggs should be
shared between each buildout. bootstrap needs to run only once. A
single Zope 3 setup is shared between all buildouts. It's basically
just setting up a Zope 3 instance, and on my machine that takes less
than a second.

That would be nicer.

Hm, we should ask Jim.

People should at the very least mark changes that have an effect on
the tutorial. What would be the right place for this? We should
starting maintaining a CHANGES.txt file anyhow, perhaps that can be
used for this.

It's a difficult balance to make. Just realize that running an
individual buildout of a tutorial is extremely fast (after the first
