Overview

Package genericapiserver contains code to setup a generic kubernetes-like API server. This does not contain any kubernetes API specific code. Note that this is a work in progress. We are pulling out generic code (specifically from pkg/master and pkg/apiserver) here. We plan to move this package into a separate repo on github once it is done. For more details: https://github.com/kubernetes/kubernetes/issues/2742
