//  Description:
//      This file is the IDL file for the IClusCfgServer interface of the
//      Cluster Setup application.
//
//      The IClusCfgServer interface provides the functions required to gather
//      information about storage devices, networks, the operating
//      system, etc. on a computer. It also has functions to form a cluster
//      on this computer, to add this node to a cluster, to remove this node
//      from a cluster, etc.
