Ah, makes sense now. 'develop = src/my.package' probably leads to
development of a package called my.package, but the name in setup.py may
be totally different, so the develop-eggs dir seems the good place to
look. And Tres pointed to the line in zc.buildout that cleans this
directory up, so it looks safe to me.
