# Tests for the -q command line option.
#
# The -q option only looks at the dependencies between the targets.
# None of the commands in the targets are run, not even those that are
# prefixed with '+'.

# This test consists of several parts:
#
#	main		Delegates to the actual tests.
#
#	commands	Ensures that none of the targets is made.
#
#	variants	Ensures that the up-to-date status is correctly
#			reported in both compat and jobs mode, and for several
#			kinds of make targets.
