#
# Tests for combining the command line options -n (no action) and -t (touch).
# This combination is unusual and probably doesn't ever happen in practice,
# but still make needs to behave as expected.  The option -n is stronger than
# -t, so instead of being touched, the commands of the targets are printed.
#
# See also:
#	opt-touch-jobs.mk contains the same test without the option -n.
