          The usual output is:
          ApplicationName RevisionNumber
          ApplicationName ROOT_Version
          ApplicationName KM3NET
          ApplicationName ./command/line --arguments --which --can
          contain
          also
          multiple lines
          and --addtional flags
          etc.
          ApplicationName Linux ... (just the `uname -a` output)
