Create a Participant and assign roles using API (outside the process)

Question

I want to create a participant in the BPM directory using API, which I believe is available in the fuegopapi-client.jar file. What is missing is a sample or documentation for that API. PAPI Javadocs found on the web don't cover the rest of the API available in the mentioned jar file.
There are examples of how to do this within a process, but not outside the context of the process. Any references to documentation or samples, you may have come across is greatly appreciated. I have not had success in finding anything on this forum and the web. Thanks.

          if (directorySessionRol==null){
                         DirectoryConfigurationManager.getRuntime().setPropertiesFileName(props.getProperty("fuego.custom.replication.config.directoryFile").trim());
Directory.DEFAULT_ENGINE_PRESET);
                         DirectoryPassport directoryPassport = DirectoryPassport.createWithIDAndPreset(props.getProperty("fuego.custom.replication.config.directoryId").trim(), props.getProperty("fuego.custom.replication.config.preset").trim());
                              if (directoryPassport == null)
                                   throw new RuntimeException("Invalid directory passport for FDI");
                              System.out.println("openSesionDFI: " +directoryPassport.getUrl());
                              directoryPassport.fillPassport();          
                              directorySessionRol = Directory.startAdminSession(directoryPassport);
          System.out.println("openSesionDFI: " +"fin");
