Mock sm2 as a CommonJs module

my module

var SoundMan = require('SoundManager').SoundManager
  , soundMan = require('SoundManager').soundManager
    
//profit!

SoundManager2

(function(window, _undefined){
    if ( window === _undefined ) 
        throw new Error('SoundManager requries a window object!');
    
    // here be the lib code   
    // use can attach what you must to the window object here!
    
    if ( typeof module === "object" && module && typeof module.exports === "object" ) {
        //CommonJs
        // the "strict" way is to never expose as a global object if possible, so no sm2 on the window
        // you could still export it via module.exports and also add to window if you want though. no added benefit
        // unless your app already expects both, which should not be the case
    	module.exports.SoundManager = SoundManager; 
    	module.exports.soundManager = soundManager; 
    	
    } else if ( typeof define === "function" && define.amd ) {
        // AMD - requireJs
    	define( "SoundManager", [], function () { 
    	    return {
    	        SoundManager: SoundManager
    	        soundManager: soundManager
    	    }; 
        });
    } else {
        //Normal Browser
        window.SoundManager = SoundManager;
    	window.soundManager = soundManager;
    }

})(window);
