I went over the script and the documentation and it looks pretty good to
me at this point. My only comment would be potentially referencing the
TuxMake container images in the example section to give folks a
"prebuilt" container option while getting the kernel.org container
images sorted out but that can always be done in a follow-up change.

I will apply this to kbuild-next-unstable shortly to give folks a week
or so to voice any objections or give critical review comments.

Cheers,
Nathan
