          be available for the CPC.
  
          For a list of available features, see section "Features" in the
          :term:`HMC API`, or use the :meth:`feature_info` method.

          Returns:
  
            bool: `True` if the feature is enabled, or `False` if the feature is
            disabled (but available).

            :exc:`ValueError`: Features are not supported on the HMC.
