  * @class KDBusServiceStarter kdbusservicestarter.h <KDBusServiceStarter>
  *
  * A generic D-Bus service starter, using KServiceTypeTrader.
  * The default implementation starts new processes, but this interface can
  * also be reimplemented by specific applications to provide dlopened in-process D-Bus objects.
  * This interface is similar to the startService() function found in QDBusConnectionInterface, but
  * with the added benefit of using KServiceTypeTrader (and, therefore, additional constraints and the
  * ability to search the standard KDE dirs).
  * @author David Faure <faure@kde.org>
  *
  * @deprecated since 5.61, use D-Bus activation instead
