      3  1.1     apb # Test behaviour of recursive make and vars set on command line.
      4  1.6  rillig #
      5  1.6  rillig # FIXME: The purpose of this test is unclear.  The test uses six levels of
      6  1.6  rillig # sub-makes, which makes it incredibly hard to understand.  There must be at
      7  1.6  rillig # least an introductory explanation about what _should_ happen here.
      8  1.6  rillig # The variable names are terrible, as well as their values.
      9  1.6  rillig #
     10  1.6  rillig # This test produces different results if the large block with the condition
     11  1.6  rillig # "scope == SCOPE_GLOBAL" in Var_SetWithFlags is removed.  This test should
     12  1.6  rillig # be rewritten to make it clear why there is a difference and why this is
     13  1.6  rillig # actually intended.  Removing that large block of code makes only this test
     14  1.6  rillig # and vardebug.mk fail, which is not enough.
