+
+## usage
+
+This example is longer than the implementation.
+
+```js
+var s = new stream.PassThrough()
+concat(s, function (err, buf) {
+  if (err) throw err
+  console.error(buf)
+})
+s.write('abc')
+setTimeout(function () {

+}, 10)
+setTimeout(function () {
+  s.write('456')
+}, 20)
+setTimeout(function () {
+  s.end('789')
