// Amazon Simple Notification Service (Amazon SNS) is a web service that enables
// you to build distributed web-enabled applications. Applications can use Amazon
// SNS to easily push real-time notification messages to interested subscribers
// over multiple delivery protocols. For more information about this product
// see http://aws.amazon.com/sns (http://aws.amazon.com/sns/). For detailed
// information about Amazon SNS features and their associated API calls, see
// the Amazon SNS Developer Guide (http://docs.aws.amazon.com/sns/latest/dg/).
//
// We also provide SDKs that enable you to access Amazon SNS from your preferred
// programming language. The SDKs contain functionality that automatically takes
// care of tasks such as: cryptographically signing your service requests, retrying
// requests, and handling error responses. For a list of available SDKs, go
// to Tools for Amazon Web Services (http://aws.amazon.com/tools/).
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
