+The browser build does not depend on Node's `stream` module. A document is still a
+readable stream, but only the parts a PDF document needs are implemented: `on`,
+`once`, `off`, `emit`, `pipe` and async iteration. `read`, `setEncoding`,
+`destroy`, `stream.pipeline` and the `readable`, `error` and `close` events are
+available in Node only.
