+# Publisher

+

+## Modules

+- api - exports the publisher interface for clients and providers to import

+- features - used for managing the feature repository for publisher

+- installer - provides a simple install script 

+- provider - provides an implementation of the publisher api, this implementation assumes the controller has a single identity for publishing to DMAAP message router

+- sample.client - a dummy client that posts a simple message to a configured topic during its initialization
