                'application privileged helper tools. Applications can send '
                'messages to the XPC Service daemon, which runs as root, using '
                'the low-level XPC Service <code>C API</code> or the high '
                'level <code>NSXPCConnection API</code> in order to handle '
                'tasks that require elevated privileges (such as network '
                'connections). Applications are responsible for providing the '
                'protocol definition which serves as a blueprint of the XPC '
                'services. Developers typically use XPC Services to provide '
                'applications stability and privilege separation between the '
                'application client and the daemon.(Citation: '
