  \brief The QRemoteFactory class creates QRemoteInterface objects.

  The remote factory creates a QRemoteInterface object for a given key with
  QRemoteFactory::create(key).

  The Remote-controls are either built-in or dynamically loaded from a RC
  plugin (see \l QRemotePlugin).

  QRemoteFactory::keys() returns a list of valid keys. Qt currently
  ships with "rc1".
