Sure.  I still don't know what that means. :)

*Maybe* you'd like to use workingenv to install eggs and use buildout to do
other things like set up zope instances.  If that's the case, then it's
just a matter of writing recipes that take into account how you install eggs
and scripts. But maybe that's not what you mean.

Specific use cases would help to guide this.

No, it's more familiar -- to these people.

The alternative seems to be a custom shell script.  I can see how this
would be familiar to the people who wrote it.  When there are well
established and documented buildout recipes for doing common tasks, then
there will be familiar tools, for some definition of familiar.

So lets see. To contribute to the wider Python community, I should
change the name of my Company or change jobs. Hm.

In what way does buildout "ride roughly with existing python techs".
It builds on setuptools.  Do you mean that if there is another
community package that does something somewhat similar, we aren't
allow to create a similar package just because we are associated with
the Zope project.

Oh, I have to use a different repository.

Has it occurred to you that the problem here doesn't lie with the
Zope project or Zope developers?

Oh, as someone who gets lots of criticism, I really don't think that
is much of a problem.

How are we doing this?  The primary forum for discussing buildout
is the distutils sig.  It is released through PyPI.  It doesn't depend
on any other technology that we use -- other than Python.

What should I do to make it more accessible?
