// An object representing a temporary / scratch directory that should be
// cleaned up (recursively) when this object goes out of scope. Since deletion
// occurs during the destructor, no further error handling is possible if the
// directory fails to be deleted. As a result, deletion is not guaranteed by
// this class. (However note that, whenever possible, by default
// CreateUniqueTempDir creates the directory in a location that is
// automatically cleaned up on reboot, or at other appropriate times.)
// Multiple calls to the methods which establish a temporary directory
// (CreateUniqueTempDir, CreateUniqueTempDirUnderPath, and Set) must have
// intervening calls to Delete or Take, or the calls will fail.
