// This example demonstrates calling the Cloud Pub/Sub API. As of 22
// Oct 2014, the Cloud Pub/Sub API is only available if you're
// whitelisted. If you're interested in using it, please apply for the
// Limited Preview program at the following form:
// http://goo.gl/Wql9HL
//
// Also, before running this example, be sure to enable Cloud Pub/Sub
// service on your project in Developer Console at:
// https://console.developers.google.com/
//
// Unless you run this sample on Compute Engine instance, please
// create a new service account and download a JSON key file for it at
// the developer console: https://console.developers.google.com/
//
// It has the following subcommands:
//
//  create_topic <name>
//  delete_topic <name>
//  create_subscription <name> <linked_topic>
//  delete_subscription <name>
//  publish <topic> <message>
//  pull_messages <subscription> <numworkers>
//  publish_messages <topic> <numworkers>
//
// You can choose any names for topic and subscription as long as they
// follow the naming rule described at:
// https://cloud.google.com/pubsub/overview#names
//
// You can create/delete topics/subscriptions by self-explanatory
// subcommands.
//
// The "publish" subcommand is for publishing a single message to a
// specified Cloud Pub/Sub topic.
//
// The "pull_messages" subcommand is for continuously pulling messages
// from a specified Cloud Pub/Sub subscription with specified number
// of workers.
//
// The "publish_messages" subcommand is for continuously publishing
