Indeed! That’s the spirit! :)

There may only be one change to the sample, one line added, but the real change will happen in two files (maybe 3). And really, they aren’t big changes.

Indeed, but someone has to push the edge and give it a go?

I need to get myself a PI3. I have to wait till the 15th to order mine, but that doesn’t mean I can’t start getting ct-ng there. I know there are others out there waiting for aarch64 support, so let’s do this.
