+
+Easy way to create a `Stream` that is both `readable` and `writable`. 
+
+* Pass in optional `write` and `end` methods.
+* `through` takes care of pause/resume logic if you use `this.queue(data)` instead of `this.emit('data', data)`.
+* Use `this.pause()` and `this.resume()` to manage flow.
+* Check `this.paused` to see current flow state. (`write` always returns `!this.paused`).
+
+This function is the basis for most of the synchronous streams in 
+[event-stream](http://github.com/dominictarr/event-stream).
+
+``` js
+var through = require('through')
+
+through(function write(data) {
+    this.queue(data) //data *must* not be null
+  },
+  function end () { //optional
+    this.queue(null)
+  })
+```
+
+Or, can also be used _without_ buffering on pause, use `this.emit('data', data)`,
+and this.emit('end')
+
+``` js
+var through = require('through')
+
+through(function write(data) {
+    this.emit('data', data)
+    //this.pause() 
+  },
+  function end () { //optional
+    this.emit('end')
+  })
+```
+
+## Extended Options
+
+You will probably not need these 99% of the time.
+
+### autoDestroy=false
+
+By default, `through` emits close when the writable
+and readable side of the stream has ended.
+If that is not desired, set `autoDestroy=false`.
+
+``` js
+var through = require('through')
+
+//like this
+var ts = through(write, end, {autoDestroy: false})
+//or like this
+var ts = through(write, end)
+ts.autoDestroy = false
+```
