Library for functional reactive programming (FRP); profiling libraries

 Reactive-banana is a library for Functional Reactive Programming (FRP).
 .
 FRP offers an elegant and concise way to express interactive programs
 such as graphical user interfaces, animations, computer music or
 robot controllers. It promises to avoid the spaghetti code that is
 all too common in traditional approaches to GUI programming.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
