# would use both libnutscan and libcommon or similar libs. Here we did have
# a problem with nut-scanner using two copies of common.c and conflicting
# copies of "nut_debug_level" making fun of our debug-logging attempts.
# One solution to tackle if needed for those cases would be to make some
# dynamic/shared libnutcommon (etc.)
