flocker-go
==========
[![circleci](https://circleci.com/gh/ClusterHQ/flocker-go.svg)](https://circleci.com/gh/ClusterHQ/flocker-go)
flocker-go implements the package `flocker` that will let you easily interact
with a Flocker Control Service.
What can it do?
---------------
You can check the package documentation here: https://godoc.org/github.com/ClusterHQ/flocker-go
TODO
----
- Define a proper interface `flockerClientable` with all the needed methods for
wrapping the Flocker API.
