Ocsfml -  an OCaml port of the C++ SFML library (version >= 2.0)

Require :
  - SFML >= 2.0
  - OCaml >= 3.12 
  - cmake >= 2.8
  - findlib >= 1.2.7
  - a C++ compiler having a minimal support of C++11 
    (Tested with :
    	Linux :
	 - gcc 4.6.1
	 - clang 2.9
	OS X (10.7) :
	 - gcc 4.5
	 - clang 2.9
	Windows :
	 - VC++ 10 ) 
   - boost
   - flexlink (only on Windows)

Install :

1) Configuration
The configuration tool is cmake.
When running cmake ocamlc must in the PATH environment variable.
Following instructions will assume that you are in the cmake build directory.

2) Compiling and installing Ocsfml

Ocsfml use a preprocessor library (external_cpp) to facilitate C++/OCaml binding.
Thus, you must first compile and install it; then you could compile ocsfml itself.
Target to build are (in the same order) :
  * external_cpp
  * install_external_cpp
  * all
  * install

For instance :

- With make :
make external_cpp
sudo make install_external_cpp
make
sudo make install

- With nmake :
nmake external_cpp
nmake install_external_cpp
nmake 
nmake install


3) Compiling and installing the tests [optional]
You may want to tests Ocsfml. Build the targets 'tests' and 'install_tests'.
Native and byte-code executable should be installed in CMAKE_INSTALL_PREFIX/share/Ocsfml/Test (on Unix) or CMAKE_INSTALL_PREFIX/Ocsfml/Test (on Windows)

4) Using Ocsfml in Ocaml top-level
Ocsfml may be used in the ocaml top-level :

#use "topfind" ;;
#require "ocsfml.graphics" ;;
open OcsfmlWindow ;;
open OcsfmlGraphics ;;
let vm = VideoMode.({width = 400 ; height = 400 ; bits_per_pixel = 32 }) ;;
let app = new render_window vm "Ocsfml Window" ;;
let shape = mk_circle_shape ~radius:50. ~fill_color:Color.yellow ~outline_color:Color.blue ~outline_thickness:10. ~position:(100., 100.) ();;
app#clear () ;;
app#draw shape ;;
app#display () ;;

5) Integrating Ocsfml in Ocamlbuild toolchain
Add '-use-ocamlfind' flag when invoking ocamlbuild.
In your _tags file, specify package( ocsfml.LLL ) with LLL the lower-case name of one of the SFML module (system, window, graphics, audio or network)
