+// 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.
