+// 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,

+// Note that if you want to run closure, and also to use Module

+// can continue to use Module afterwards as well.
