+// Package session provides a way to create service clients with shared configuration
+// and handlers.
+//
+// Generally this package should be used instead of the `defaults` package.
+//
+// A session should be used to share configurations and request handlers between multiple
+// service clients. When service clients need specific configuration aws.Config can be
+// used to provide additional configuration directly to the service client.

+// A Session provides a central location to create service clients from and

+// Sessions are safe to create service clients concurrently, but it is not safe
+// to mutate the session concurrently.

+// New creates a new instance of the handlers merging in the provided Configs
+// on top of the SDK's default configurations. Once the session is created it
+// can be mutated to modify Configs or Handlers. The session is safe to be read
+// concurrently, but it should not be written to concurrently.
+//
+// Example:
+//     // Create a session with the default config and request handlers.
+//     sess := session.New()

+// and handlers. If any additional configs are provided they will be merged
+// on top of the session's copied config.
