+ (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.")
