[Nut-upsdev] Still plugging away at the repo conversion

Hi Eric,

Thanks for this update, and the time you put into helping us (and others).
Do your best, and tell us back when you're ready.
I'll be releasing 2.6.3 tomorrow, and will then have a Christmas break
(back ~ January 3rd).

cheers,
Arnaud
