A simple sample showing how to use my "sdl" and "webgl" node libraries

greengl.js

// To test on Ubuntu, install the requirements to build
// `apt-get install libsdl-image1.2-dev libsdl-ttf2.0-dev libsdl1.2-dev libgles2-mesa-dev`
// Then load the node libraries needed `npm install sdl webgl`
// Then run this script!

SDL = require('sdl');
gl = require('webgl');

SDL.init(SDL.INIT.VIDEO);
var screen = SDL.setVideoMode(640, 480, 0, SDL.SURFACE.OPENGL);
SDL.events.on("QUIT", process.exit)
SDL.events.on("KEYDOWN", function (evt) { if (evt.sym === 27) process.exit() });
process.on('exit', function () { SDL.quit(); });

gl.viewport(0, 0, screen.w, screen.h);
gl.clearColor(0, 0.5, 0, 1);
gl.clear(gl.COLOR_BUFFER_BIT);

SDL.GL.swapBuffers();

I've been trying to get this to work, but I can't get past the first line of code "SDL = require('sdl');
Are there more details orbetter-yet, a full working version I can obtain? I included a copy of require.js and this code hangs or ends in the function 'function'. I also have those dev libraries, but not sure how this all comes together? Help is appreciated. Just trying to get webgl working with SDL.
