+ (description
+ "A clean and powerful stream processing library that lets you build
+and connect reusable streaming components. Advantages over traditional streaming
+libraries:
+@itemize
+@item Concise API: Use simple commands like @code{for}, (@code{>->}), @code{await},
+and @code{yield}
+@item Blazing fast: Implementation tuned for speed, including shortcut fusion
+@item Lightweight Dependency: pipes is small and compiles very rapidly, including
+dependencies
+@item Elegant semantics: Use practical category theory
+@item ListT: Correct implementation of @code{ListT} that interconverts with pipes
+@item Bidirectionality: Implement duplex channels
