# SUBDIRS are explicitly a listing of all the directories that make
# must recurse into BEFORE processing the current directory.
#
# These python scripts must be moved into a sub-directory, and _only_
# executed IF they need to be, and all the nut-scanner sources need
# to be moved out of a sub-directory into this directory.

# Anyway, for the time being, we force build in ./ before nut-scanner,
# to have nutscan-{usb,snmp}.h built before going into the nut-scanner
# sub-directory
