+ "This package provides a dependent sum is a generalization of a
+particular way of thinking about the @code{Either} type. @code{Either a b}
+can be thought of as a 2-tuple @code{(tag, value)}, where the value of the tag
+determines the type of the value. In particular, either @code{tag = Left} and
+@code{value :: a} or @code{tag = Right} and @code{value :: b}. This package
+allows you to define your own dependent sum types by using your own \"tag\"
+types.")
