+### A little history of "AsyncWrap/AsyncHook" and its incarnations
+
+1. First implementation was called **[AsyncListener](https://github.com/nodejs/node-v0.x-archive/pull/6011)** in node v0.11 but was [removed from core](https://github.com/nodejs/node-v0.x-archive/pull/8110) prior to Nodejs v0.12
+2. Second implementation called **[AsyncWrap, async-wrap or async_wrap](https://github.com/nodejs/node-eps/blob/async-wrap-ep/XXX-asyncwrap-api.md)** was included to Nodejs v0.12.
+    - `AsyncWrap` is unofficial and undocumented but is currently in Nodejs versions 6 & 7
+    - `cls-hooked` currently uses `AsyncWrap`
+3. Third implementation and [offically Node-eps accepted](https://github.com/nodejs/node-eps/blob/master/006-asynchooks-api.md) **AsyncHook API** was recently merged into Nodejs's core master branch and is expected to be in Nodejs 8. :)

 Continuation-local storage works like thread-local storage in threaded
 programming, but is based on chains of Node-style callbacks instead of threads.
 The standard Node convention of functions calling functions is very similar to
