   1 -- 2021-10-07, issue #7705
   2 --
   3 -- Non-existent config file given explicitly (via option or environment variable)
   4 -- should not be filled with default content.
   5 -- Rather, an error should be raised.
   6 --
   7 -- See also @PackageTests/UserConfig/cabal.test.hs@ for testing of command
   8 -- @user-config@.
   9 --
  10 -- We use the @info@ command as it does not have side-effects.
  11 -- Does not really matter which command we use for this test,
  12 -- except that it should accept option @--config-file@.
  13 --
  14 -- This is a golden value test that reports the produced error message.
  15 -- Needs to be checked manually whether it meets expectations.
