# Recursive make is considered harmful:

#
# For now this Makefile uses explicit dependencies. The project
# hasn't grown big enough to need something complicated, and the
# dependency tracking files are an ugly annoyance.
#
# This file includes */module.mk files which add on to variables:
# FOO += bar/baz
#
#
# Set (or uncomment) SKIP if you wish to avoid something.
# For example, you may prefer the /bin/kill from util-linux or bsdutils.
