Yeah. Although, ultimately, I want to escape the command-line
interface. I'd still much rather use a Python API. I'll need to
understand the internals a lot better. I expect looking at the
things you suggested will help me do that. Generally, the farther I
go and the more I learn of setuptools, the less I actually reply on

Yup. All good points. It's not obvious how to expose this.
I think what's needed is a way to say more about how a particular
package should be
handled. This kind of detail doesn't lend itself to command-line
arguments, which is
why zc.buildout is command-line based. :)
