Tits module contains input and output devices for grabbing from and rendering to many common multimedia input/output software frameworks.

val init : unit -> unit

Initialize the module. This is done implicitely if you use any of the module's API but is here to provide an easy way to make sure that the module is explicitely linked by the OCaml compiler. NOT thread-safe!
