I think I wrote something to that effect in the earlier posts, so nice to
hear someone else feels that way - more so, a member of that project! :)
The repo copy saved in NUT organization was more about ensuring that code
is available for wannabe porters who would make a real NUT driver covering
more APC devices (likely not myself - short on time, hardware and skill for
that).
Thanks,
Jim
