[Zope3-dev] speeding up buildout of individual parts

I noticed the updates in the last days, didn't change much for me
though. The longest time is the 'svn up' in the Zope 3 checkout. It
takes about 32 seconds when I run 'bin/buildout install zope3' (Zope 3
being a zc.recipe.zope3checkout). This is a long time if you're running
bin/buildout many times while working on recipes or buildouts.

Right. I guess 'depending' was a term I chose because I didn't know
better. I'm pretty sure that I didn't change any configuration in the
buildout at all, but the zope3checkout install is run every time, even
when I specify just the zope3instance to be installed.

Right. Again, that's not the time-critical part so not a problem.
