honestly, it seems to me that buildout tries to do too much.  it's trying to 
handle both repeatable deployment recipes AND providing a sandbox within which 
to run things.  there may not be a point to having an extra layer on top of 
buildout, but buildout sure does seem to me a bit heavy if all i want is a 
sandbox.  so now i have to learn the workingenv way if i just need a sandbox, 
but i have to learn the buildout way if i also want repeatable deployments?

this is shortsighted, IMO.  i know zope quite well, but i bounced off of 
buildout b/c it required too much knowledge to even get started.  i think it's 
much more likely that people from the greater python community will pick up 
and start using workingenv than they will zc.buildout.

personally, i like chris mcdonough's approach with his buildit package.  it 
does two things:

- it retrieves files from anywhere on the 'net (cvs, svn, tarball, whatever) 
and puts them where you want them on your target machine(s)

- it launches external scripts that then perform whatever final configuration 
you may want to perform.

buildit is also recipe driven, and it's smart enough to pick up where it left 
off on a previous run, a'la make.  i'd guess that you could use buildit and 
workingenv to accomplish pretty much everything you can do w/ zc.buildout, and 
you wouldn't have to bend your brain so much to do so.
