// types of scheduling that can be achieved and the required input parameters
// for starting a download.  Note that BackgroundDownloadService with a valid
// storage directory will persist the requests across restarts.  This means that
// any feature requesting a download will have to implement a download::Client
// interface so this class knows who to contact when a download completes after
// a process restart.
// See the embedder specific factories for creation options.
