      + StartupOption.BACKUP.getName() + "] | \n\t["
      + StartupOption.CHECKPOINT.getName() + "] | \n\t["
      + StartupOption.FORMAT.getName() + " ["
      + StartupOption.CLUSTERID.getName() + " cid ] ["
      + StartupOption.FORCE.getName() + "] ["
      + StartupOption.NONINTERACTIVE.getName() + "] ] | \n\t["
      + StartupOption.UPGRADE.getName() + 
        " [" + StartupOption.CLUSTERID.getName() + " cid]" +
        " [" + StartupOption.RENAMERESERVED.getName() + "<k-v pairs>] ] | \n\t["
      + StartupOption.UPGRADEONLY.getName() + 
        " [" + StartupOption.CLUSTERID.getName() + " cid]" +
