// The Amazon Simple Workflow Service (Amazon SWF) makes it easy to build applications
// that use Amazon's cloud to coordinate work across distributed components.
// In Amazon SWF, a task represents a logical unit of work that is performed
// by a component of your workflow. Coordinating tasks in a workflow involves
// managing intertask dependencies, scheduling, and concurrency in accordance
// with the logical flow of the application.
//
// Amazon SWF gives you full control over implementing tasks and coordinating
// them without worrying about underlying complexities such as tracking their
// progress and maintaining their state.
//
// This documentation serves as reference only. For a broader overview of the
// Amazon SWF programming model, see the Amazon SWF Developer Guide (http://docs.aws.amazon.com/amazonswf/latest/developerguide/).
