+duplexer2 [![build status](https://travis-ci.org/deoxxa/duplexer2.png)](https://travis-ci.org/deoxxa/fork)
+=========
+
+Like duplexer (http://npm.im/duplexer) but using streams2.
+
+Overview
+--------
+
+duplexer2 is a reimplementation of [duplexer](http://npm.im/duplexer) using the
+readable-stream API which is standard in node as of v0.10. Everything largely
+works the same.
+
+Installation
+------------
+
+Available via [npm](http://npmjs.org/):
+
+> $ npm install duplexer2
+
+Or via git:
+
+> $ git clone git://github.com/deoxxa/duplexer2.git node_modules/duplexer2
+
+API
+---
+
+**duplexer2**
+
+Creates a new `DuplexWrapper` object, which is the actual class that implements
+most of the fun stuff. All that fun stuff is hidden. DON'T LOOK.
+
+```javascript
+duplexer2([options], writable, readable)
+```
+
+```javascript
+var duplex = duplexer2(new stream.Writable(), new stream.Readable());
+```
+
+Arguments
+
+* __options__ - an object specifying the regular `stream.Duplex` options, as
+  well as the properties described below.
+* __writable__ - a writable stream
+* __readable__ - a readable stream
+
+Options
+
+* __bubbleErrors__ - a boolean value that specifies whether to bubble errors
+  from the underlying readable/writable streams. Default is `true`.
+
+Example
+-------
+
+Also see [example.js](https://github.com/deoxxa/duplexer2/blob/master/example.js).
+
+Code:
+
+```javascript
+var stream = require("stream");
+
+var duplexer2 = require("duplexer2");
+
+var writable = new stream.Writable({objectMode: true}),
+    readable = new stream.Readable({objectMode: true});
+
+writable._write = function _write(input, encoding, done) {
+  if (readable.push(input)) {
+    return done();
+  } else {
+    readable.once("drain", done);
+  }
+};
+
+readable._read = function _read(n) {
+  // no-op
+};
+
+// simulate the readable thing closing after a bit
+writable.once("finish", function() {
+  setTimeout(function() {
+    readable.push(null);
+  }, 500);
+});
+
+var duplex = duplexer2(writable, readable);
+
+duplex.on("data", function(e) {
+  console.log("got data", JSON.stringify(e));
+});
+
+duplex.on("finish", function() {
+  console.log("got finish event");
+});
+
+duplex.on("end", function() {
+  console.log("got end event");
+});
+
+duplex.write("oh, hi there", function() {
+  console.log("finished writing");
+});
+
+duplex.end(function() {
+  console.log("finished ending");
+});
+```
+
+Output:
+
+```
+got data "oh, hi there"
+finished writing
+got finish event
+finished ending
+got end event
+```
