// This example demonstrates calling the Cloud Pub/Sub API. As of 20
// Aug 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/
//
// It has 8 subcommands as follows:
//
// PROJ list_topics
// PROJ create_topic TOPIC
// PROJ delete_topic TOPIC
// PROJ list_subscriptions
// PROJ create_subscription SUBSCRIPTION LINKED_TOPIC
// PROJ delete_subscription SUBSCRIPTION
// PROJ connect_irc TOPIC SERVER CHANNEL
// PROJ pull_messages SUBSCRIPTION
//
// You can use either of your alphanumerical or numerial Cloud Project
// ID for PROJ. You can choose any names for TOPIC and SUBSCRIPTION as
// long as they follow the naming rule described at:
// https://developers.google.com/pubsub/overview#names
//
// You can list/create/delete topics/subscriptions by self-explanatory
// subcommands, as well as connect to an IRC channel and publish
// messages from the IRC channel to a specified Cloud Pub/Sub topic by
// the "connect_irc" subcommand, or continuously pull messages from a
// specified Cloud Pub/Sub subscription and display the data by the
// "pull_messages" subcommand.
