3# Tests for combining the command line options -n (no action) and -t (touch).
4# This combination is unusual and probably doesn't ever happen in practice,
5# but still make needs to behave as expected.  The option -n is stronger than
6# -t, so instead of being touched, the commands of the targets are printed.
7#
8# See also:
9#	opt-touch-jobs.mk contains the same test without the option -n.
