Making things simpler...
This package provides a buildout recipe for creating a Zope 2 instance based around a deployment.
The deployment concept originates from zc.recipe.deployment and allows the deployment to control where resources of a particular type are created.
While zc.recipe.deployment is suited to production use, you will likely find that gocept.recipe.deploymentsandbox is more useful for development.
This recipe is only compatible with Zope 2.12+.
