// Implementation of PROOF static resources.                            //
// The purpose of this class is to provide a standard interface to      //
// static config files. It interprets Proof config files (proof.conf)   //
// and sorts the contents into TProofNodeInfo objects. Master info will //
// be placed in fMaster (of type TProofNodeInfo). Submaster info will   //
// be put in fSubmasterList (a TList of TProofNodeInfo objects), while  //
// workers (and condorworkers) will be placed in fWorkerList (a TList   //
// of TProofNodeInfo objects).                                          //
//                                                                      //
