This is awesome, and by that I don't mean the fact that we have a plone 
buildout, but that we actually have Zope 2 recipes for buildout. I hope 
they can be moved to svn.zope.org for further development to benefit the 
whole Zope 2 community.

I also see that workingenv was abandoned. That's very good to hear 
because buildout has a lot of machinery for installing eggs already, it 
would just've been duplicated with workingenv...

gocept's Zope 3 instance recipe actually installs a script into the 
top-level bin directory, so you can do:

   $ bin/buildout
   $ bin/instance fg

Where 'instance' is the name of the instance configuration section in 
buildout.cfg. So, if you have multiple instances, you can start them all 
with according scripts from 'bin'.

It'd be really cool if z2c.recipe.zope2instance would do the same. To be 
frank, I think having to mess around in 'parts' sucks. I would even 
argue that app data like logs, databases, etc. shouldn't be in 'parts' 
either. You should be able to delete 'parts' and lose nothing 
(disclaimer: this is my view, not sure how "Buildout Jim" see it ;)).

Yeah! We all owe beers to Hanno.
