-// The Module object: Our interface to the outside world. We import
-// and export values on it. There are various ways Module can be used:
-// 1. Not defined. We create it here
-// 2. A function parameter, function(Module) { ..generated code.. }
-// 3. pre-run appended it, var Module = {}; ..generated code..
-// 4. External script tag defines var Module.
-// We need to check if Module already exists (e.g. case 3 above).
-// Substitution will be replaced with actual code on later stage of the build,
-// this way Closure Compiler will not mangle it (e.g. case 4. above).
-// Note that if you want to run closure, and also to use Module
-// after the generated code, you will need to define var Module = {};
-// before the code. Then that object will be used in the code, and you
-// can continue to use Module afterwards as well.
