Overview

Package kubectl is a set of libraries that are used by the kubectl command line tool. They are separated out into a library to support unit testing. Most functionality should be included in this package, and the main kubectl should really just be an entry point.

A set of common functions needed by cmd/kubectl and pkg/kubectl packages.
