     This package is the core haskell98 part of the parsec2
-    package, intended to preserve its simplicity and portability.

-    Note, that the module names overlap with those of parsec from the Haskell
-    Platform, therefore I do not recommend to unconditionally use parsec1 (or
-    parsec2 and parsec3) as dependency in cabal files of packages for hackage.
-    But you may want to develop your code using these limited and portable
-    parsec1 functions and finally change the dependency from parsec1 to parsec
-    in order to avoid module ambiguities for users just installing your package.
-    Your own module ambiguities are best avoided by hiding packages.

-    This version only differs from the pervious one by improved error messages
-    for try (positions are not reset), tokens and thus string (longer
-    unexpected strings are now reported to match the error position).
-    The notFollowedBy-parser was generalized (as in parsec-3) so
-    characters in messages are now shown in single instead of double
-    quotes.
-    Also (as since parsec-3.1.2) lookAhead no longer consumes tokens on success
-    (so that the many-parser can detect this).
+    This version differs from the pervious one only by a MonadFail
+    instance to let it compile with ghc-8.8.
