   * `emitBinary()`: Returns a binary for the module, which you can then compile and run in the browser.
   * `emitText()`: Returns a text representation of the module, in s-expression format.
   * `validate()`: Validates the module, checking it for correctness.
-  * `optimize()`: Optimize the module.
+  * `optimize()`: Runs the standard optimization passes on the module.
+  * `runPasses(passes)`: Runs the specified passes on the module.
   * `autoDrop()`: Automatically inserts `drop` operations. This lets you not worry about dropping when creating your code.
   * `interpret()`: Run the module in the Binaryen interpreter (creates the module, and calls the start method). Useful for debugging.
   * `dispose()`: Cleans up the module. If the Binaryen object can be garbage-collected anyhow, you don't need to do this, but if it stays around - e.g. if you create multiple `Module`s over time - then you should call this once a `Module` is no longer needed. (As binaryen.js uses compiled C++ code, we can't just rely on normal garbage collection to clean things up internally.)
