      3 # Tests for the -q command line option.
      4 #
      5 # The -q option only looks at the dependencies between the targets.
      6 # None of the commands in the targets are run, not even those that are
      7 # prefixed with '+'.

      9 # This test consists of several parts:
     10 #
     11 #	main		Delegates to the actual tests.
     12 #
     13 #	commands	Ensures that none of the targets is made.
     14 #
     15 #	variants	Ensures that the up-to-date status is correctly
     16 #			reported in both compat and jobs mode, and for several
     17 #			kinds of make targets.
