An example of how module.declare and require would be defined on the client side

ExampleRequire.js

window.module = (function() {
	var module = {};
	var modules = {};
	module.require = function require(mod_name) {
		return modules[mod_name];
	};

	module.declare = function declare(f) {
		if(typeof f === 'function') {
			var m = {};
			modules[f.name] = f.call(module, module.require, m, module) || m;
		} else {
			// ??? what do I name the module ???
		}
	};
	return module;
})();
