-NOTE: This example does not build and is being updated.
-Experimental example code, likely to change.
-Users should not attempt to run this code till this warning is removed.
-
-C++ Client implementation for Cloud Pub/Sub service
-(https://developers.google.com/apis-explorer/#p/pubsub/v1beta1/).
-
-"Google Cloud Pub/Sub" API needs to be enabled at
-https://console.developers.google.com/project to open the access for a client. 
-Select the project name, select the "APIs" under "APIs & auth", and turn
-on "Google Cloud Pub/Sub" API. 
-
-To run the client from Google Compute Engine (GCE), the GCE instance needs to
-be created with scope "https://www.googleapis.com/auth/cloud-platform" as below:
-
-gcloud compute instances create instance-name 
-    --image debian-7 --scopes https://www.googleapis.com/auth/cloud-platform
-
-
-To run the client:
-make pubsub_client
-bins/opt/pubsub_client --project_id="your project id"
