    # We need to break dependency circuit between optparse-applicative,
    # process, unix and bytestring. Newer versions of Cabal are capable
    # of coming up with these automatically, but older ones need a hint.
    # Specifically, we need to inform Cabal that:
    #
    # * optparse-applicative doesn't use process; 
    # * QuickCheck uses the old random package; and
    # * tasty doesn't use unix.
