-# MapStream
-
-Refactored out of [event-stream](https://github.com/dominictarr/event-stream)
-
-##map (asyncFunction[, options])
-
-Create a through stream from an asyncronous function.
-
-``` js
-var map = require('map-stream')
-
-map(function (data, callback) {
- //transform data
- // ...
- callback(null, data)
-})
-
-```
-
-Each map MUST call the callback. It may callback with data, with an error or with no arguments,
-
- * `callback()` drop this data.
- this makes the map work like `filter`,
- note:`callback(null,null)` is not the same, and will emit `null`
-
- * `callback(null, newData)` turn data into newData
-
- * `callback(error)` emit an error for this item.
-
->Note: if a callback is not called, `map` will think that it is still being processed,
->every call must be answered or the stream will not know when to end.
->
->Also, if the callback is called more than once, every call but the first will be ignored.
-
-##Options
-
- * `failures` - `boolean` continue mapping even if error occured. On error `map-stream` will emit `failure` event. (default: `false`)
