## Purpose
This repository contains functions to be consumed by various Kubernetes and
out-of-tree CSI components like external provisioner to facilitate migration of
code from Kubernetes In-tree plugin code to CSI plugin repositories.
Consumers can make use of this repository can make use of functions like
`TranslateToCSI` and `TranslateToInTree` functions to translate PV sources.
