      3 # Unit tests for make(1)
      4 # The main targets are:
      5 # 
      6 # all:	run all the tests
      7 # test:	run 'all', and compare to expected results
      8 # accept: move generated output to expected results
      9 #
     10 # Adding a test case.  
     11 # Each feature should get its own set of tests in its own suitably
     12 # named makefile (*.mk), with its own set of expected results (*.exp),
     13 # and it should be added to the TESTNAMES list.
