+The Cabal-syntax package
+========================
+
+See the [Cabal web site] for more information.
+
+The `Cabal-syntax` package defines the syntax of the `.cabal` file format
+and provides tools for parsing `.cabal` files.
+
+More information
+================
+
+Please see the [Cabal web site] for the [user guide] and [API
+documentation]. There is additional information available on the
+[development wiki].
+
+[user guide]:        http://www.haskell.org/cabal/users-guide

+Bugs
+====
+
+Please report bugs and feature requests to Cabal's [bug tracker].
+
+
+Your help
+---------
+
+To help Cabal's development, it is enormously helpful to know from
+Cabal's users what their most pressing problems are with Cabal and
+[Hackage]. You may have a favourite Cabal bug or limitation. Look at
+Cabal's [bug tracker]. Ensure that the problem is reported there and
+adequately described. Comment on the issue to report how much of a
+problem the bug is for you. Subscribe to the issues's notifications to
+discussed requirements and keep informed on progress. For feature
+requests, it is helpful if there is a description of how you would
+expect to interact with the new feature.
