// Package config provides utilities for loading configuration from multiple
// sources that can be used to configure the SDK's API clients, and utilities.
//
// The config package will load configuration from environment variables, AWS
// shared configuration file (~/.aws/config), and AWS shared credentials file
// (~/.aws/credentials).
//
// Use the LoadDefaultConfig to load configuration from all the SDK's supported
// sources, and resolve credentials using the SDK's default credential chain.
//
// LoadDefaultConfig allows for a variadic list of additional Config sources that can
// provide one or more configuration values which can be used to programmatically control the resolution
// of a specific value, or allow for broader range of additional configuration sources not supported by the SDK.
// A Config source implements one or more provider interfaces defined in this package. Config sources passed in will
// take precedence over the default environment and shared config sources used by the SDK. If one or more Config sources
// implement the same provider interface, priority will be handled by the order in which the sources were passed in.
//
// A number of helpers (prefixed by “With“)  are provided in this package that implement their respective provider
// interface. These helpers should be used for overriding configuration programmatically at runtime.
