The BasicIO backend supports only simple input and output. Support for Password and LinePrewritten features can be added with a shim from Shim.

basicIO :: Wizard BasicIO a -> Wizard BasicIO a #

A simple identity function, used to restrict types if the type inferred by GHC is too general. You could achieve the same effect with a type signature, but this is slightly less typing.
