Nit: could perhaps that line be broken in a bit more readable way? build_parser = subparser.add_parser('build', help='Builds a kernel with KUnit tests. ' 'Successful build depends on a clean source tree. ' 'Run mrproper to clean generated artifacts for prior ' 'ARCH=foo kernel build. ' 'Run "make ARCH=foo mrproper"') (fixed "artifacts" while I was in the neighborhood :) jon
