      lnc.showLineNumbers(false);
      lnc.setDisplayMode(true);
              lnc.setRevisionInformation(ri);
      lnc.showRevisionAuthor(true);
      System.out.println("ci"+lnc.isShowingChangeInformation());
      System.out.println("ri"+lnc.isShowingRevisionInformation());

  Revision r = new Revision();
