> Affects Versions: 1.1.0
> Reporter: Colin Patrick McCabe

>
> Some improvements to the manual NN metadata recovery tools.
> Specifically, we want the Offline Edit Viewer (oev) tool to prints out the
> highest generation stamp that was encountered when processing the edit log.
> We also want OEV to look for large gaps in the generation stamp, as these can
> indicate corruption. The minimum gap to look for should be configurable with
> -G or --genStampGap.
