+# PauseStream
+
+This is a `Stream` that will strictly buffer when paused.
+Connect it to anything you need buffered.
+
+``` js
+  var ps = require('pause-stream')();
+
+  badlyBehavedStream.pipe(ps.pause())
+
+  aLittleLater(function (err, data) {
+    ps.pipe(createAnotherStream(data))
+    ps.resume()
+  })
+```
+
+`PauseStream` will buffer whenever paused.
+it will buffer when yau have called `pause` manually.
+but also when it's downstream `dest.write()===false`.
+it will attempt to drain the buffer when you call resume
+or the downstream emits `'drain'`
+
+`PauseStream` is tested using [stream-spec](https://github.com/dominictarr/stream-spec)
+and [stream-tester](https://github.com/dominictarr/stream-tester)
