|
|
// 2. A function parameter, function(Module) { ..generated code.. }
|
|
// 3. pre-run appended it, var Module = {}; ..generated code..
|
|

|
|
// 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 = {};
