%% @doc <fullname>Amazon Simple Workflow Service</fullname>
%%
%% 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 <i>task</i> 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 <i> <a
%% href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/">Amazon
%% SWF Developer Guide</a> </i>.
