+    (description "@code{wizards} is a package designed for the quick
+and painless development of @emph{interrogative} programs, which revolve around
+a \"dialogue\" with the user, who is asked a series of questions in a
+sequence much like an installation wizard.
+
+Everything from interactive system scripts, to installation wizards, to full-blown
+shells can be implemented with the support of @code{wizards}.
+
+It is developed transparently on top of a free monad, which separates out the
+semantics of the program from any particular interface.  A variety of backends
+exist, including console-based @code{System.Console.Wizard.Haskeline} and
+@code{System.Console.Wizard.BasicIO}, and the pure @code{System.Console.Wizard.Pure}.
+It is also possible to write your own backends, or extend existing back-ends with
+new features.  While both built-in IO backends operate on a console, there is no
+reason why @code{wizards} cannot also be used for making GUI wizard interfaces.
+
+See the github page for examples on usage:
+
+@url{http://www.github.com/liamoc/wizards}
+
+For creating backends, the module @code{System.Console.Wizard.Internal} has a brief
+tutorial.")
