+%description
+This package contains the "Control.Monad.Fail" module providing the
+<https://prime.haskell.org/wiki/Libraries/Proposals/MonadFail MonadFail> class
+that became available in <https://hackage.haskell.org/package/base-4.9.0.0
+base-4.9.0.0> for older 'base' package versions.
+
+This package turns into an empty package when used with GHC versions which
+already provide the "Control.Monad.Fail" module to make way for GHC's own
+"Control.Monad.Fail" module.
