Are you one of the people who doesn't agree? If so, what's your problem 
with buildout? Hopefully we can sort that rather than having to maintain 
two ways of doing things...

Interesting. I never noticed that... Hopefully that change will make it 
into Zope 2.12 final?

Cool. If only the zope2 egg could expose these now, it would make the 
buildout.cfg simpler... just the matter of passing in the config. I 
wonder if anyone can think of a nicer way of doing that?

Indeed. I'd suggest that if the python used to run zopectl is different 
to the one specified in runzope, there will be problems. My guess is 
that these are just symptoms of how runzope and zopectl used to be 
construted...

When runzope and zopectl are built by buildout, this is already the 
case... One python is used for both...

What's Windows? Seriously though, I haven't needed to run Zope 2.12 on 
Windows, so I don't know...
