React is an OCaml module for functional reactive programming (FRP). It provides support to program with time varying values : applicative events and signals. React doesn't define any primitive event or signal, this lets the client chooses the concrete timeline. React is made of a single, independent, module and distributed under the new BSD license. Given an absolute notion of time Rtime helps you to manage a timeline and provides time stamp events, delayed events and delayed signals. dbuenzli/react
