-- Significantly optimized all iteration based collection methods such as `each`, `map`, `filter`, etc (#1245, #1246, #1247).
-
-# v2.0.0
-
-Lots of changes here!
-
-First and foremost, we have a slick new [site for docs](https://caolan.github.io/async/). Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well.
-
-The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before.
-
-We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size.
-
-Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy.
-
-Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that:
-
-1. Takes a variable number of arguments
-2. The last argument is always a callback
-3. The callback can accept any number of arguments
-4. The first argument passed to the callback will be treated as an error result, if the argument is truthy
-5. Any number of result arguments can be passed after the "error" argument
-6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop.
-
-There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, and `filter`.
-
-Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`.
-
-Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205).
-
-## New Features
-
-- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) (#984, #996)
-- Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) (#984, #996)
-- Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. (#568, #1038)
-- Collection methods now accept ES2015 iterators.  Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. (#579, #839, #1074)
-- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. (#1157, #1177)
-- Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. (#1007, #1027)
-- Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object.  (#942, #1012, #1095)
-- `constant` supports dynamic arguments -- it will now always use its last argument as the callback. (#1016, #1052)
-- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. (#940, #1053)
-- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) (#1140).
-- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function. (#608, #1055, #1099, #1100)
-- You can now limit the concurrency of `auto` tasks. (#635, #637)
-- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. (#1058)
-- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. (#1161)
-- `retry` will now pass all of the arguments the task function was resolved with to the callback (#1231).
-- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. (#868, #1030, #1033, #1034)
-- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. (#1170)
-- `applyEach` and `applyEachSeries` now pass results to the final callback. (#1088)
-
-## Breaking changes
-
-- Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. (#814, #815, #1048, #1050)
-- `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) (#1036, #1042)
-- Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. (#696, #704, #1049, #1050)
-- `map` used to return an object when iterating over an object.  `map` now always returns an array, like in other libraries.  The previous object behavior has been split out into `mapValues`. (#1157, #1177)
-- `filter`, `reject`, `some`, `every`, and related functions now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. (#118, #774, #1028, #1041)
-- `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. (#778, #847)
-- `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. (#1054, #1058)
-- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function (#1217, #1224)
-- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs (#1205).
-- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. (#724, #1078)
-- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays (#1237)
-- Dropped support for Component, Jam, SPM, and Volo (#1175, ##176)
-
-## Bug Fixes
-
-- Improved handling of no dependency cases in `auto` & `autoInject` (#1147).
-- Fixed a bug where the callback generated by `asyncify` with  `Promises` could resolve twice (#1197).
-- Fixed several documented optional callbacks not actually being optional (#1223).
-
-## Other
-
-- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases.
-- Added `find` as an alias for `detect. (as well as `findLimit` and `findSeries`).
-- Various doc fixes (#1005, #1008, #1010, #1015, #1021, #1037, #1039, #1051, #1102, #1107, #1121, #1123, #1129, #1135, #1138, #1141, #1153, #1216, #1217, #1232, #1233, #1236, #1238)

+Async is a utility module which provides straight-forward, powerful functions
+for working with asynchronous JavaScript. Although originally designed for
+use with [Node.js](http://nodejs.org) and installable via `npm install async`,
+it can also be used directly in the browser.
 
-*For Async v1.5.x documentation, go [HERE](https://github.com/caolan/async/blob/v1.5.2/README.md)*
+Async is also installable via:
+
+- [bower](http://bower.io/): `bower install async`
+- [component](https://github.com/component/component): `component install
+  caolan/async`
+- [jam](http://jamjs.org/): `jam install async`

+
+Async provides around 20 functions that include the usual 'functional'
+suspects (`map`, `reduce`, `filter`, `each`…) as well as some common patterns
+for asynchronous control flow (`parallel`, `series`, `waterfall`…). All these
+functions assume you follow the Node.js convention of providing a single
+callback as the last argument of your `async` function.
+
+
+## Quick Examples
+
+```javascript
+async.map(['file1','file2','file3'], fs.stat, function(err, results){
+    // results is now an array of stats for each file
+});
+
+async.filter(['file1','file2','file3'], fs.exists, function(results){
+    // results now equals an array of the existing files
+});
+
+async.parallel([
+    function(){ ... },
+    function(){ ... }
+], callback);
+
+async.series([
+    function(){ ... },
+    function(){ ... }
+]);
+```
+
+There are many more functions available so take a look at the docs below for a
+full list. This module aims to be comprehensive, so if you feel anything is
+missing please create a GitHub issue for it.
+
+## Common Pitfalls <sub>[(StackOverflow)](http://stackoverflow.com/questions/tagged/async.js)</sub>
+### Synchronous iteration functions
+
+If you get an error like `RangeError: Maximum call stack size exceeded.` or other stack overflow issues when using async, you are likely using a synchronous iterator.  By *synchronous* we mean a function that calls its callback on the same tick in the javascript event loop, without doing any I/O or using any timers.  Calling many callbacks iteratively will quickly overflow the stack. If you run into this issue, just defer your callback with `async.setImmediate` to start a new call stack on the next tick of the event loop.
+
+This can also arise by accident if you callback early in certain cases:
+
+```js
+async.eachSeries(hugeArray, function iterator(item, callback) {
+  if (inCache(item)) {
+    callback(null, cache[item]); // if many items are cached, you'll overflow
+  } else {
+    doSomeIO(item, callback);
+  }
+}, function done() {
+  //...
+});
+```
+
+Just change it to:
+
+```js
+async.eachSeries(hugeArray, function iterator(item, callback) {
+  if (inCache(item)) {
+    async.setImmediate(function () {
+      callback(null, cache[item]);
+    });
+  } else {
+    doSomeIO(item, callback);
+  //...
+```
+
+Async guards against synchronous functions in some, but not all, cases.  If you are still running into stack overflows, you can defer as suggested above, or wrap functions with [`async.ensureAsync`](#ensureAsync)  Functions that are asynchronous by their nature do not have this problem and don't need the extra callback deferral.
+
+If JavaScript's event loop is still a bit nebulous, check out [this article](http://blog.carbonfive.com/2013/10/27/the-javascript-event-loop-explained/) or [this talk](http://2014.jsconf.eu/speakers/philip-roberts-what-the-heck-is-the-event-loop-anyway.html) for more detailed information about how it works.
+
+
+### Multiple callbacks
+
+Make sure to always `return` when calling a callback early, otherwise you will cause multiple callbacks and unpredictable behavior in many cases.
+
+```js
+async.waterfall([
+    function (callback) {
+        getSomething(options, function (err, result) {
+          if (err) {
+            callback(new Error("failed getting something:" + err.message));
+            // we should return here
+          }
+          // since we did not return, this callback still will be called and
+          // `processData` will be called twice
+          callback(null, result);
+        });
+    },
+    processData
+], done)
+```
+
+It is always good practice to `return callback(err, result)`  whenever a callback call is not the last statement of a function.
+
+
+### Binding a context to an iterator
+
+This section is really about `bind`, not about `async`. If you are wondering how to
+make `async` execute your iterators in a given context, or are confused as to why
+a method of another library isn't working as an iterator, study this example:
+
+```js
+// Here is a simple object with an (unnecessarily roundabout) squaring method
+var AsyncSquaringLibrary = {
+  squareExponent: 2,
+  square: function(number, callback){
+    var result = Math.pow(number, this.squareExponent);
+    setTimeout(function(){
+      callback(null, result);
+    }, 200);
+  }
+};
+
+async.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){
+  // result is [NaN, NaN, NaN]
+  // This fails because the `this.squareExponent` expression in the square
+  // function is not evaluated in the context of AsyncSquaringLibrary, and is
+  // therefore undefined.
+});
+
+async.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){
+  // result is [1, 4, 9]
+  // With the help of bind we can attach a context to the iterator before
+  // passing it to async. Now the square function will be executed in its
+  // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent`
+  // will be as expected.
+});
+```

+Applies the function `iterator` to each item in `arr`, in parallel.
+The `iterator` is called with an item from the list, and a callback for when it
+has finished. If the `iterator` passes an error to its `callback`, the main
+`callback` (for the `each` function) is immediately called with the error.
+
+Note, that since this function applies `iterator` to each item in parallel,
+there is no guarantee that the iterator functions will complete in order.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err)` which must be called once it has
+  completed. If no error has occurred, the `callback` should be run without
+  arguments or with an explicit `null` argument.  The array index is not passed
+  to the iterator.  If you need the index, use [`forEachOf`](#forEachOf).
+* `callback(err)` - *Optional* A callback which is called when all `iterator` functions
+  have finished, or an error occurs.
+
+__Examples__
+
+
+```js
+// assuming openFiles is an array of file names and saveFile is a function
+// to save the modified contents of that file:
+
+async.each(openFiles, saveFile, function(err){
+    // if any of the saves produced an error, err would equal that error
+});
+```
+
+```js
+// assuming openFiles is an array of file names
+
+async.each(openFiles, function(file, callback) {
+
+  // Perform operation on file here.
+  console.log('Processing file ' + file);
+
+  if( file.length > 32 ) {
+    console.log('This file name is too long');
+    callback('File name too long');
+  } else {
+    // Do work to process file here
+    console.log('File processed');
+    callback();
+  }
+}, function(err){
+    // if any of the file processing produced an error, err would equal that error
+    if( err ) {
+      // One of the iterations produced an error.
+      // All processing will now stop.
+      console.log('A file failed to process');
+    } else {
+      console.log('All files have been processed successfully');

+Like `each`, except that it iterates over objects, and passes the key as the second argument to the iterator.
+
+__Arguments__
+
+* `obj` - An object or array to iterate over.
+* `iterator(item, key, callback)` - A function to apply to each item in `obj`.
+The `key` is the item's key, or index in the case of an array. The iterator is

+<a name="map" />
+### map(arr, iterator, [callback])
+
+Produces a new array of values by mapping each value in `arr` through
+the `iterator` function. The `iterator` is called with an item from `arr` and a
+callback for when it has finished processing. Each of these callback takes 2 arguments:
+an `error`, and the transformed item from `arr`. If `iterator` passes an error to its
+callback, the main `callback` (for the `map` function) is immediately called with the error.
+
+Note, that since this function applies the `iterator` to each item in parallel,
+there is no guarantee that the `iterator` functions will complete in order.
+However, the results array will be in the same order as the original `arr`.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err, transformed)` which must be called once
+  it has completed with an error (which can be `null`) and a transformed item.
+* `callback(err, results)` - *Optional* A callback which is called when all `iterator`
+  functions have finished, or an error occurs. Results is an array of the
+  transformed items from the `arr`.
+
+__Example__
+
+```js

+_The callback for each `iterator` call only accepts a single argument of `true` or
+`false`; it does not accept an error argument first!_ This is in-line with the

+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
+  The `iterator` is passed a `callback(truthValue)`, which must be called with a
+  boolean argument once it has completed.
+* `callback(results)` - *Optional* A callback which is called after all the `iterator`

+<a name="reduce" />
+### reduce(arr, memo, iterator, [callback])
+
+__Aliases:__ `inject`, `foldl`
+
+Reduces `arr` into a single value using an async `iterator` to return
+each successive step. `memo` is the initial state of the reduction.
+This function only operates in series.
+
+For performance reasons, it may make sense to split a call to this function into
+a parallel map, and then use the normal `Array.prototype.reduce` on the results.
+This function is for situations where each step in the reduction needs to be async;
+if you can get the data before reducing it, then it's probably a good idea to do so.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `memo` - The initial state of the reduction.
+* `iterator(memo, item, callback)` - A function applied to each item in the
+  array to produce the next step in the reduction. The `iterator` is passed a
+  `callback(err, reduction)` which accepts an optional error as its first
+  argument, and the state of the reduction as the second. If an error is
+  passed to the callback, the reduction is stopped and the main `callback` is
+  immediately called with the error.
+* `callback(err, result)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished. Result is the reduced value.
+
+__Example__
+
+```js
+async.reduce([1,2,3], 0, function(memo, item, callback){
+    // pointless async:
+    process.nextTick(function(){
+        callback(null, memo + item)

+
+<a name="detect" />
+### detect(arr, iterator, [callback])
+
+Returns the first value in `arr` that passes an async truth test. The
+`iterator` is applied in parallel, meaning the first iterator to return `true` will
+fire the detect `callback` with that result. That means the result might not be
+the first item in the original `arr` (in terms of order) that passes the test.
+
+If order within the original `arr` is important, then look at [`detectSeries`](#detectSeries).
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
+  The iterator is passed a `callback(truthValue)` which must be called with a
+  boolean argument once it has completed. **Note: this callback does not take an error as its first argument.**
+* `callback(result)` - *Optional* A callback which is called as soon as any iterator returns
+  `true`, or after all the `iterator` functions have finished. Result will be
+  the first item in the array that passes the truth test (iterator) or the
+  value `undefined` if none passed.  **Note: this callback does not take an error as its first argument.**
+

+### sortBy(arr, iterator, [callback])

+Sorts a list by the results of running each `arr` value through an async `iterator`.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err, sortValue)` which must be called once it
+  has completed with an error (which can be `null`) and a value to use as the sort
+  criteria.
+* `callback(err, results)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished, or an error occurs. Results is the items from
+  the original `arr` sorted by the values returned by the `iterator` calls.
+
+__Example__
+
+```js
+async.sortBy(['file1','file2','file3'], function(file, callback){

+## Control Flow
+
+<a name="series" />
+### series(tasks, [callback])
+
+Run the functions in the `tasks` array in series, each one running once the previous
+function has completed. If any functions in the series pass an error to its
+callback, no more functions are run, and `callback` is immediately called with the value of the error.
+Otherwise, `callback` receives an array of results when `tasks` have completed.
+
+It is also possible to use an object instead of an array. Each property will be
+run as a function, and the results will be passed to the final `callback` as an object
+instead of an array. This can be a more readable way of handling results from
+[`series`](#series).
+
+**Note** that while many implementations preserve the order of object properties, the
+[ECMAScript Language Specification](http://www.ecma-international.org/ecma-262/5.1/#sec-8.6)
+explicitly states that
+
+> The mechanics and order of enumerating the properties is not specified.
+
+So if you rely on the order in which your series of functions are executed, and want
+this to work on all platforms, consider using an array.
+
+__Arguments__
+
+* `tasks` - An array or object containing functions to run, each function is passed
+  a `callback(err, result)` it must call on completion with an error `err` (which can
+  be `null`) and an optional `result` value.
+* `callback(err, results)` - An optional callback to run once all the functions
+  have completed. This function gets a results array (or object) containing all
+  the result arguments passed to the `task` callbacks.
+
+__Example__

+<a name="parallel" />
+### parallel(tasks, [callback])
+
+Run the `tasks` array of functions in parallel, without waiting until the previous

+callback, the main `callback` is immediately called with the value of the error.
+Once the `tasks` have completed, the results are passed to the final `callback` as an
+array.
+
+**Note:** `parallel` is about kicking-off I/O tasks in parallel, not about parallel execution of code.  If your tasks do not use any timers or perform any I/O, they will actually be executed in series.  Any synchronous setup sections for each task will happen one after the other.  JavaScript remains single-threaded.
+
+It is also possible to use an object instead of an array. Each property will be
+run as a function and the results will be passed to the final `callback` as an object
+instead of an array. This can be a more readable way of handling results from

+__Arguments__
+
+* `tasks` - An array or object containing functions to run. Each function is passed
+  a `callback(err, result)` which it must call on completion with an error `err`
+  (which can be `null`) and an optional `result` value.
+* `callback(err, results)` - An optional callback to run once all the functions
+  have completed successfully. This function gets a results array (or object) containing all
+  the result arguments passed to the task callbacks.

+  argument is an error (which can be `null`) and any further arguments will be
+  passed as arguments in order to the next task.
+* `callback(err, [results])` - An optional callback to run once all the functions
+  have completed. This will be passed the results of the last task's callback.
+
+
+
+__Example__
+
+```js
+async.waterfall([
+    function(callback) {
+        callback(null, 'one', 'two');
+    },
+    function(arg1, arg2, callback) {
+      // arg1 now equals 'one' and arg2 now equals 'two'
+        callback(null, 'three');
+    },
+    function(arg1, callback) {
+        // arg1 now equals 'three'
+        callback(null, 'done');
+    }
+], function (err, result) {
+    // result now equals 'done'
+});
+```
+Or, with named functions:
+
+```js
+async.waterfall([
+    myFirstFunction,
+    mySecondFunction,
+    myLastFunction,
+], function (err, result) {
+    // result now equals 'done'
+});
+function myFirstFunction(callback) {
+  callback(null, 'one', 'two');
+}
+function mySecondFunction(arg1, arg2, callback) {
+  // arg1 now equals 'one' and arg2 now equals 'two'
+  callback(null, 'three');
+}
+function myLastFunction(arg1, callback) {
+  // arg1 now equals 'three'
+  callback(null, 'done');
+}
+```
+
+Or, if you need to pass any argument to the first function:
+
+```js
+async.waterfall([
+    async.apply(myFirstFunction, 'zero'),
+    mySecondFunction,
+    myLastFunction,
+], function (err, result) {
+    // result now equals 'done'
+});
+function myFirstFunction(arg1, callback) {
+  // arg1 now equals 'zero'
+  callback(null, 'one', 'two');
+}
+function mySecondFunction(arg1, arg2, callback) {
+  // arg1 now equals 'one' and arg2 now equals 'two'
+  callback(null, 'three');
+}
+function myLastFunction(arg1, callback) {
+  // arg1 now equals 'three'
+  callback(null, 'done');
+}

+<a name="compose" />
+### compose(fn1, fn2...)
+
+Creates a function which is a composition of the passed asynchronous
+functions. Each function consumes the return value of the function that
+follows. Composing functions `f()`, `g()`, and `h()` would produce the result of
+`f(g(h()))`, only this version uses callbacks to obtain the return values.
+
+Each function is executed with the `this` binding of the composed function.
+
+__Arguments__
+
+* `functions...` - the asynchronous functions to compose
+
+
+__Example__
+
+```js
+function add1(n, callback) {
+    setTimeout(function () {
+        callback(null, n + 1);
+    }, 10);
+}
+
+function mul3(n, callback) {
+    setTimeout(function () {
+        callback(null, n * 3);
+    }, 10);

+<a name="seq" />
+### seq(fn1, fn2...)
+
+Version of the compose function that is more natural to read.
+Each function consumes the return value of the previous function.
+It is the equivalent of [`compose`](#compose) with the arguments reversed.
+
+Each function is executed with the `this` binding of the composed function.
+
+__Arguments__
+
+* `functions...` - the asynchronous functions to compose
+
+
+__Example__
+
+```js
+// Requires lodash (or underscore), express3 and dresende's orm2.
+// Part of an app, that fetches cats of the logged user.
+// This example uses `seq` function to avoid overnesting and error
+// handling clutter.
+app.get('/cats', function(request, response) {
+  var User = request.models.User;
+  async.seq(
+    _.bind(User.get, User),  // 'User.get' has signature (id, callback(err, data))

+<a name="applyEach" />
+### applyEach(fns, args..., callback)
+
+Applies the provided arguments to each function in the array, calling
+`callback` after all functions have completed. If you only provide the first
+argument, then it will return a function which lets you pass in the
+arguments as if it were a single function call.
+
+__Arguments__
+
+* `fns` - the asynchronous functions to all call with the same arguments
+* `args...` - any number of separate arguments to pass to the function
+* `callback` - the final argument should be the callback, called when all
+  functions have completed processing
+
+
+__Example__
+
+```js
+async.applyEach([enableSearch, updateSchema], 'bucket', callback);

+
+<a name="queue" />
+### queue(worker, [concurrency])
+
+Creates a `queue` object with the specified `concurrency`. Tasks added to the
+`queue` are processed in parallel (up to the `concurrency` limit). If all
+`worker`s are in progress, the task is queued until one becomes available.
+Once a `worker` completes a `task`, that `task`'s callback is called.
+
+__Arguments__
+
+* `worker(task, callback)` - An asynchronous function for processing a queued
+  task, which must call its `callback(err)` argument when finished, with an
+  optional `error` as an argument.  If you want to handle errors from an individual task, pass a callback to `q.push()`.
+* `concurrency` - An `integer` for determining how many `worker` functions should be
+  run in parallel.  If omitted, the concurrency defaults to `1`.  If the concurrency is `0`, an error is thrown.
+
+__Queue objects__
+
+The `queue` object returned by this function has the following properties and
+methods:
+
+* `length()` - a function returning the number of items waiting to be processed.
+* `started` - a function returning whether or not any items have been pushed and processed by the queue
+* `running()` - a function returning the number of items currently being processed.
+* `workersList()` - a function returning the array of items currently being processed.
+* `idle()` - a function returning false if there are items waiting or being processed, or true if not.
+* `concurrency` - an integer for determining how many `worker` functions should be
+  run in parallel. This property can be changed after a `queue` is created to
+  alter the concurrency on-the-fly.
+* `push(task, [callback])` - add a new task to the `queue`. Calls `callback` once
+  the `worker` has finished processing the task. Instead of a single task, a `tasks` array
+  can be submitted. The respective callback is used for every task in the list.
+* `unshift(task, [callback])` - add a new task to the front of the `queue`.
+* `saturated` - a callback that is called when the `queue` length hits the `concurrency` limit,
+   and further tasks will be queued.
+* `empty` - a callback that is called when the last item from the `queue` is given to a `worker`.
+* `drain` - a callback that is called when the last item from the `queue` has returned from the `worker`.
+* `paused` - a boolean for determining whether the queue is in a paused state
+* `pause()` - a function that pauses the processing of tasks until `resume()` is called.
+* `resume()` - a function that resumes the processing of queued tasks when the queue is paused.
+* `kill()` - a function that removes the `drain` callback and empties remaining tasks from the queue forcing it to go idle.
+
+__Example__
+
+```js
+// create a queue object with concurrency 2
+
+var q = async.queue(function (task, callback) {
+    console.log('hello ' + task.name);
+    callback();
+}, 2);
+
+
+// assign a callback
+q.drain = function() {
+    console.log('all items have been processed');
+}
+
+// add some items to the queue
+
+q.push({name: 'foo'}, function (err) {
+    console.log('finished processing foo');
+});
+q.push({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+
+// add some items to the queue (batch-wise)
+
+q.push([{name: 'baz'},{name: 'bay'},{name: 'bax'}], function (err) {
+    console.log('finished processing item');
+});
+
+// add some items to the front of the queue
+
+q.unshift({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+```
+
+
+---------------------------------------
+
+<a name="priorityQueue" />
+### priorityQueue(worker, concurrency)
+
+The same as [`queue`](#queue) only tasks are assigned a priority and completed in ascending priority order. There are two differences between `queue` and `priorityQueue` objects:
+
+* `push(task, priority, [callback])` - `priority` should be a number. If an array of
+  `tasks` is given, all tasks will be assigned the same priority.
+* The `unshift` method was removed.
+
+---------------------------------------
+
+<a name="cargo" />
+### cargo(worker, [payload])
+
+Creates a `cargo` object with the specified payload. Tasks added to the
+cargo will be processed altogether (up to the `payload` limit). If the
+`worker` is in progress, the task is queued until it becomes available. Once
+the `worker` has completed some tasks, each callback of those tasks is called.

+
+While [queue](#queue) passes only one task to one of a group of workers
+at a time, cargo passes an array of tasks to a single worker, repeating
+when the worker is finished.
+
+__Arguments__
+
+* `worker(tasks, callback)` - An asynchronous function for processing an array of
+  queued tasks, which must call its `callback(err)` argument when finished, with
+  an optional `err` argument.
+* `payload` - An optional `integer` for determining how many tasks should be
+  processed per round; if omitted, the default is unlimited.
+
+__Cargo objects__
+
+The `cargo` object returned by this function has the following properties and
+methods:
+
+* `length()` - A function returning the number of items waiting to be processed.
+* `payload` - An `integer` for determining how many tasks should be
+  process per round. This property can be changed after a `cargo` is created to
+  alter the payload on-the-fly.
+* `push(task, [callback])` - Adds `task` to the `queue`. The callback is called
+  once the `worker` has finished processing the task. Instead of a single task, an array of `tasks`
+  can be submitted. The respective callback is used for every task in the list.
+* `saturated` - A callback that is called when the `queue.length()` hits the concurrency and further tasks will be queued.
+* `empty` - A callback that is called when the last item from the `queue` is given to a `worker`.
+* `drain` - A callback that is called when the last item from the `queue` has returned from the `worker`.
+* `idle()`, `pause()`, `resume()`, `kill()` - cargo inherits all of the same methods and event calbacks as [`queue`](#queue)
+
+__Example__
+
+```js
+// create a cargo object with payload 2
+
+var cargo = async.cargo(function (tasks, callback) {
+    for(var i=0; i<tasks.length; i++){
+      console.log('hello ' + tasks[i].name);
+    }
+    callback();
+}, 2);
+
+
+// add some items
+
+cargo.push({name: 'foo'}, function (err) {
+    console.log('finished processing foo');
+});
+cargo.push({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+cargo.push({name: 'baz'}, function (err) {
+    console.log('finished processing baz');
+});
+```
+
+---------------------------------------
+
+<a name="auto" />
+### auto(tasks, [concurrency], [callback])
+
+Determines the best order for running the functions in `tasks`, based on their requirements. Each function can optionally depend on other functions being completed first, and each function is run as soon as its requirements are satisfied.
+
+If any of the functions pass an error to their callback, the `auto` sequence will stop. Further tasks will not execute (so any other functions depending on it will not run), and the main `callback` is immediately called with the error.  Functions also receive an object containing the results of functions which have completed so far.
+
+Note, all functions are called with a `results` object as a second argument,
+so it is unsafe to pass functions in the `tasks` object which cannot handle the
+extra argument.
+
+For example, this snippet of code:
+
+```js
+async.auto({
+  readData: async.apply(fs.readFile, 'data.txt', 'utf-8')
+}, callback);
+```
+
+will have the effect of calling `readFile` with the results object as the last
+argument, which will fail:
+
+```js
+fs.readFile('data.txt', 'utf-8', cb, {});
+```
+
+Instead, wrap the call to `readFile` in a function which does not forward the
+`results` object:
+
+```js
+async.auto({
+  readData: function(cb, results){
+    fs.readFile('data.txt', 'utf-8', cb);
+  }
+}, callback);
+```
+
+__Arguments__
+
+* `tasks` - An object. Each of its properties is either a function or an array of
+  requirements, with the function itself the last item in the array. The object's key
+  of a property serves as the name of the task defined by that property,
+  i.e. can be used when specifying requirements for other tasks.
+  The function receives two arguments: (1) a `callback(err, result)` which must be
+  called when finished, passing an `error` (which can be `null`) and the result of
+  the function's execution, and (2) a `results` object, containing the results of
+  the previously executed functions.
+* `concurrency` - An optional `integer` for determining the maximum number of tasks that can be run in parallel. By default, as many as possible.
+* `callback(err, results)` - An optional callback which is called when all the
+  tasks have been completed. It receives the `err` argument if any `tasks`
+  pass an error to their callback. Results are always returned; however, if
+  an error occurs, no further `tasks` will be performed, and the results
+  object will only contain partial results.
+
+
+__Example__
+
+```js
+async.auto({
+    get_data: function(callback){
+        console.log('in get_data');
+        // async code to get some data
+        callback(null, 'data', 'converted to array');
+    },
+    make_folder: function(callback){
+        console.log('in make_folder');
+        // async code to create a directory to store a file in
+        // this is run at the same time as getting the data
+        callback(null, 'folder');
+    },
+    write_file: ['get_data', 'make_folder', function(callback, results){
+        console.log('in write_file', JSON.stringify(results));
+        // once there is some data and the directory exists,
+        // write the data to a file in the directory
+        callback(null, 'filename');
+    }],
+    email_link: ['write_file', function(callback, results){
+        console.log('in email_link', JSON.stringify(results));
+        // once the file is written let's email a link to it...
+        // results.write_file contains the filename returned by write_file.
+        callback(null, {'file':results.write_file, 'email':'user@example.com'});
+    }]
+}, function(err, results) {
+    console.log('err = ', err);
+    console.log('results = ', results);
+});
+```
+
+This is a fairly trivial example, but to do this using the basic parallel and
+series functions would look like this:
+
+```js
+async.parallel([
+    function(callback){
+        console.log('in get_data');
+        // async code to get some data
+        callback(null, 'data', 'converted to array');
+    },
+    function(callback){
+        console.log('in make_folder');
+        // async code to create a directory to store a file in
+        // this is run at the same time as getting the data
+        callback(null, 'folder');
+    }
+],
+function(err, results){
+    async.series([
+        function(callback){
+            console.log('in write_file', JSON.stringify(results));
+            // once there is some data and the directory exists,
+            // write the data to a file in the directory
+            results.push('filename');
+            callback(null);
+        },
+        function(callback){
+            console.log('in email_link', JSON.stringify(results));
+            // once the file is written let's email a link to it...
+            callback(null, {'file':results.pop(), 'email':'user@example.com'});
+        }
+    ]);
+});
+```
+
+For a complicated series of `async` tasks, using the [`auto`](#auto) function makes adding
+new tasks much easier (and the code more readable).
+
+
+---------------------------------------
+
+<a name="retry" />
+### retry([opts = {times: 5, interval: 0}| 5], task, [callback])
+
+Attempts to get a successful response from `task` no more than `times` times before
+returning an error. If the task is successful, the `callback` will be passed the result
+of the successful task. If all attempts fail, the callback will be passed the error and
+result (if any) of the final attempt.
+
+__Arguments__
+
+* `opts` - Can be either an object with `times` and `interval` or a number.
+  * `times` - The number of attempts to make before giving up.  The default is `5`.
+  * `interval` - The time to wait between retries, in milliseconds.  The default is `0`.
+  * If `opts` is a number, the number specifies the number of times to retry, with the default interval of `0`. 
+* `task(callback, results)` - A function which receives two arguments: (1) a `callback(err, result)`
+  which must be called when finished, passing `err` (which can be `null`) and the `result` of
+  the function's execution, and (2) a `results` object, containing the results of
+  the previously executed functions (if nested inside another control flow).
+* `callback(err, results)` - An optional callback which is called when the
+  task has succeeded, or after the final failed attempt. It receives the `err` and `result` arguments of the last attempt at completing the `task`.
+
+The [`retry`](#retry) function can be used as a stand-alone control flow by passing a callback, as shown below:
+
+```js
+// try calling apiMethod 3 times
+async.retry(3, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+```js
+// try calling apiMethod 3 times, waiting 200 ms between each retry 
+async.retry({times: 3, interval: 200}, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+```js
+// try calling apiMethod the default 5 times no delay between each retry 
+async.retry(apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+It can also be embedded within other control flow functions to retry individual methods
+that are not as reliable, like this:
+
+```js
+async.auto({
+    users: api.getUsers.bind(api),
+    payments: async.retry(3, api.getPayments.bind(api))
+}, function(err, results) {
+  // do something with the results
+});
+```
+
+
+---------------------------------------
+
+<a name="iterator" />
+### iterator(tasks)
+
+Creates an iterator function which calls the next function in the `tasks` array,
+returning a continuation to call the next one after that. It's also possible to
+“peek” at the next iterator with `iterator.next()`.
+
+This function is used internally by the `async` module, but can be useful when
+you want to manually control the flow of functions in series.
+
+__Arguments__
+
+* `tasks` - An array of functions to run.
+
+__Example__
+
+```js
+var iterator = async.iterator([
+    function(){ sys.p('one'); },
+    function(){ sys.p('two'); },
+    function(){ sys.p('three'); }
+]);
+
+node> var iterator2 = iterator();
+'one'
+node> var iterator3 = iterator2();
+'two'
+node> iterator3();
+'three'
+node> var nextfn = iterator2.next();
+node> nextfn();
+'three'
+```
+
+---------------------------------------
+
+<a name="apply" />
+### apply(function, arguments..)
+
+Creates a continuation function with some arguments already applied.
+
+Useful as a shorthand when combined with other control flow functions. Any arguments
+passed to the returned function are added to the arguments originally passed
+to apply.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to automatically apply when the
+  continuation is called.
+
+__Example__
+
+```js
+// using apply
+
+async.parallel([
+    async.apply(fs.writeFile, 'testfile1', 'test1'),
+    async.apply(fs.writeFile, 'testfile2', 'test2'),
+]);
+
+
+// the same process without using apply
+
+async.parallel([
+    function(callback){
+        fs.writeFile('testfile1', 'test1', callback);
+    },
+    function(callback){
+        fs.writeFile('testfile2', 'test2', callback);
+    }
+]);
+```
+
+It's possible to pass any number of additional arguments when calling the
+continuation:
+
+```js
+node> var fn = async.apply(sys.puts, 'one');
+node> fn('two', 'three');
+one
+two
+three
+```
+
+---------------------------------------
+
+<a name="nextTick" />
+### nextTick(callback), setImmediate(callback)
+
+Calls `callback` on a later loop around the event loop. In Node.js this just
+calls `process.nextTick`; in the browser it falls back to `setImmediate(callback)`
+if available, otherwise `setTimeout(callback, 0)`, which means other higher priority
+events may precede the execution of `callback`.
+
+This is used internally for browser-compatibility purposes.
+
+__Arguments__
+
+* `callback` - The function to call on a later loop around the event loop.
+
+__Example__
+
+```js
+var call_order = [];
+async.nextTick(function(){
+    call_order.push('two');
+    // call_order now equals ['one','two']
+});
+call_order.push('one')
+```
+
+<a name="times" />
+### times(n, iterator, [callback])
+
+Calls the `iterator` function `n` times, and accumulates results in the same manner
+you would use with [`map`](#map).
+
+__Arguments__
+
+* `n` - The number of times to run the function.
+* `iterator` - The function to call `n` times.
+* `callback` - see [`map`](#map)
+
+__Example__
+
+```js
+// Pretend this is some complicated async factory
+var createUser = function(id, callback) {
+  callback(null, {
+    id: 'user' + id
+  })

+<a name="memoize" />
+### memoize(fn, [hasher])
+
+Caches the results of an `async` function. When creating a hash to store function
+results against, the callback is omitted from the hash and an optional hash
+function can be used.
+
+If no hash function is specified, the first argument is used as a hash key, which may work reasonably if it is a string or a data type that converts to a distinct string. Note that objects and arrays will not behave reasonably. Neither will cases where the other arguments are significant. In such cases, specify your own hash function.
+
+The cache of results is exposed as the `memo` property of the function returned
+by `memoize`.
+
+__Arguments__
+
+* `fn` - The function to proxy and cache results from.
+* `hasher` - An optional function for generating a custom hash for storing
+  results. It has all the arguments applied to it apart from the callback, and
+  must be synchronous.
+
+__Example__
+
+```js
+var slow_fn = function (name, callback) {
+    // do something
+    callback(null, result);
+};
+var fn = async.memoize(slow_fn);
+
+// fn can now be used as if it were slow_fn
+fn('some name', function () {
+    // callback
+});
+```
+
+<a name="unmemoize" />
+### unmemoize(fn)
+
+Undoes a [`memoize`](#memoize)d function, reverting it to the original, unmemoized
+form. Handy for testing.
+
+__Arguments__
+
+* `fn` - the memoized function
+
+---------------------------------------
+
+<a name="ensureAsync" />
+### ensureAsync(fn)
+
+Wrap an async function and ensure it calls its callback on a later tick of the event loop.  If the function already calls its callback on a next tick, no extra deferral is added. This is useful for preventing stack overflows (`RangeError: Maximum call stack size exceeded`) and generally keeping [Zalgo](http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony) contained.
+
+__Arguments__
+
+* `fn` - an async function, one that expects a node-style callback as its last argument
+
+Returns a wrapped function with the exact same call signature as the function passed in.
+
+__Example__
+
+```js
+function sometimesAsync(arg, callback) {
+  if (cache[arg]) {
+    return callback(null, cache[arg]); // this would be synchronous!!
+  } else {
+    doSomeIO(arg, callback); // this IO would be asynchronous
+  }
+}
+
+// this has a risk of stack overflows if many results are cached in a row
+async.mapSeries(args, sometimesAsync, done);
+
+// this will defer sometimesAsync's callback if necessary,
+// preventing stack overflows
+async.mapSeries(args, async.ensureAsync(sometimesAsync), done);
+
+```
+
+---------------------------------------
+
+<a name="constant">
+### constant(values...)
+
+Returns a function that when called, calls-back with the values provided.  Useful as the first function in a `waterfall`, or for plugging values in to `auto`.
+
+__Example__
+
+```js
+async.waterfall([
+  async.constant(42),
+  function (value, next) {
+    // value === 42
+  },
+  //...
+], callback);
+
+async.waterfall([
+  async.constant(filename, "utf8"),
+  fs.readFile,
+  function (fileData, next) {
+    //...
+  }
+  //...
+], callback);
+
+async.auto({
+  hostname: async.constant("https://server.net/"),
+  port: findFreePort,
+  launchServer: ["hostname", "port", function (cb, options) {
+    startServer(options, cb);
+  }],
+  //...
+}, callback);
+
+```
+
+---------------------------------------
+
+<a name="asyncify">
+<a name="wrapSync">
+### asyncify(func)
+
+__Alias:__ `wrapSync`
+
+Take a sync function and make it async, passing its return value to a callback. This is useful for plugging sync functions into a waterfall, series, or other async functions. Any arguments passed to the generated function will be passed to the wrapped function (except for the final callback argument). Errors thrown will be passed to the callback.
+
+__Example__
+
+```js
+async.waterfall([
+  async.apply(fs.readFile, filename, "utf8"),
+  async.asyncify(JSON.parse),
+  function (data, next) {
+    // data is the result of parsing the text.
+    // If there was a parsing error, it would have been caught.
+  }
+], callback)
+```
+
+If the function passed to `asyncify` returns a Promise, that promises's resolved/rejected state will be used to call the callback, rather than simply the synchronous return value.  Example:
+
+```js
+async.waterfall([
+  async.apply(fs.readFile, filename, "utf8"),
+  async.asyncify(function (contents) {
+    return db.model.create(contents);
+  }),
+  function (model, next) {
+    // `model` is the instantiated model object. 
+    // If there was an error, this function would be skipped.
+  }
+], callback)
+```
+
+This also means you can asyncify ES2016 `async` functions.
+
+```js
+var q = async.queue(async.asyncify(async function (file) {
+  var intermediateStep = await processFile(file);
+  return await somePromise(intermediateStep)
+}));
+
+q.push(files);
+```
+
+---------------------------------------
+
+<a name="log" />
+### log(function, arguments)
+
+Logs the result of an `async` function to the `console`. Only works in Node.js or
+in browsers that support `console.log` and `console.error` (such as FF and Chrome).
+If multiple arguments are returned from the async function, `console.log` is
+called on each argument in order.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to apply to the function.
+
+__Example__
+
+```js
+var hello = function(name, callback){
+    setTimeout(function(){
+        callback(null, 'hello ' + name);
+    }, 1000);
+};
+```
+```js
+node> async.log(hello, 'world');
+'hello world'
+```
+
+---------------------------------------
+
+<a name="dir" />
+### dir(function, arguments)
+
+Logs the result of an `async` function to the `console` using `console.dir` to
+display the properties of the resulting object. Only works in Node.js or
+in browsers that support `console.dir` and `console.error` (such as FF and Chrome).
+If multiple arguments are returned from the async function, `console.dir` is
+called on each argument in order.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to apply to the function.
+
+__Example__
+
+```js
+var hello = function(name, callback){
+    setTimeout(function(){
+        callback(null, {hello: name});
+    }, 1000);
+};
+```
+```js
+node> async.dir(hello, 'world');
+{hello: 'world'}
+```
+
+---------------------------------------
+
+<a name="noConflict" />
+### noConflict()
+
+Changes the value of `async` back to its original value, returning a reference to the
+`async` object.

-/**
- * Determines the best order for running the functions in `tasks`, based on
- * their requirements. Each function can optionally depend on other functions
- * being completed first, and each function is run as soon as its requirements
- * are satisfied.
- *
- * If any of the functions pass an error to their callback, the `auto` sequence
- * will stop. Further tasks will not execute (so any other functions depending
- * on it will not run), and the main `callback` is immediately called with the
- * error.
- *
- * Functions also receive an object containing the results of functions which
- * have completed so far as the first argument, if they have dependencies. If a
- * task function has no dependencies, it will only be passed a callback.
- *
- * @name auto
- * @static
- * @memberOf module:ControlFlow
- * @method
- * @category Control Flow
- * @param {Object} tasks - An object. Each of its properties is either a
- * function or an array of requirements, with the function itself the last item
- * in the array. The object's key of a property serves as the name of the task
- * defined by that property, i.e. can be used when specifying requirements for
- * other tasks. The function receives one or two arguments:
- * * a `results` object, containing the results of the previously executed
- *   functions, only passed if the task has any dependencies,
- * * a `callback(err, result)` function, which must be called when finished,
- *   passing an `error` (which can be `null`) and the result of the function's
- *   execution.
- * @param {number} [concurrency=Infinity] - An optional `integer` for
- * determining the maximum number of tasks that can be run in parallel. By
- * default, as many as possible.
- * @param {Function} [callback] - An optional callback which is called when all
- * the tasks have been completed. It receives the `err` argument if any `tasks`
- * pass an error to their callback. Results are always returned; however, if an
- * error occurs, no further `tasks` will be performed, and the results object
- * will only contain partial results. Invoked with (err, results).
- * @returns undefined
- * @example
- *
- * async.auto({
- *     // this function will just be passed a callback

-/**
- * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
- * tasks are specified as parameters to the function, after the usual callback
- * parameter, with the parameter names matching the names of the tasks it
- * depends on. This can provide even more readable task graphs which can be
- * easier to maintain.
- *
- * If a final callback is specified, the task results are similarly injected,
- * specified as named parameters after the initial error parameter.
- *
- * The autoInject function is purely syntactic sugar and its semantics are
- * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
- *
- * @name autoInject
- * @static
- * @memberOf module:ControlFlow
- * @method
- * @see [async.auto]{@link module:ControlFlow.auto}
- * @category Control Flow
- * @param {Object} tasks - An object, each of whose properties is a function of
- * the form 'func([dependencies...], callback). The object's key of a property
- * serves as the name of the task defined by that property, i.e. can be used
- * when specifying requirements for other tasks.
- * * The `callback` parameter is a `callback(err, result)` which must be called
- *   when finished, passing an `error` (which can be `null`) and the result of
- *   the function's execution. The remaining parameters name other tasks on
- *   which the task is dependent, and the results from those tasks are the
- *   arguments of those parameters.
- * @param {Function} [callback] - An optional callback which is called when all
- * the tasks have been completed. It receives the `err` argument if any `tasks`
- * pass an error to their callback, and a `results` object with any completed
- * task results, similar to `auto`.
- * @example
- *
- * //  The example from `auto` can be rewritten as follows:
- * async.autoInject({
- *     get_data: function(callback) {
- *         // async code to get some data
- *         callback(null, 'data', 'converted to array');
- *     },
- *     make_folder: function(callback) {
- *         // async code to create a directory to store a file in
- *         // this is run at the same time as getting the data
- *         callback(null, 'folder');
- *     },
- *     write_file: function(get_data, make_folder, callback) {
- *         // once there is some data and the directory exists,
- *         // write the data to a file in the directory
- *         callback(null, 'filename');
- *     },
- *     email_link: function(write_file, callback) {
- *         // once the file is written let's email a link to it...
- *         // write_file contains the filename returned by write_file.
- *         callback(null, {'file':write_file, 'email':'user@example.com'});
- *     }
- * }, function(err, results) {
- *     console.log('err = ', err);
- *     console.log('email_link = ', results.email_link);
- * });
- *
- * // If you are using a JS minifier that mangles parameter names, `autoInject`
- * // will not work with plain functions, since the parameter names will be
- * // collapsed to a single letter identifier.  To work around this, you can
- * // explicitly specify the names of the parameters your task function needs
- * // in an array, similar to Angular.js dependency injection.
- *
- * // This still has an advantage over plain `auto`, since the results a task
- * // depends on are still spread into arguments.
- * async.autoInject({
- *     //...
- *     write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
- *         callback(null, 'filename');
- *     }],
- *     email_link: ['write_file', function(write_file, callback) {
- *         callback(null, {'file':write_file, 'email':'user@example.com'});
- *     }]
- *     //...
- * }, function(err, results) {

- * @method
- * @category Control Flow
- * @param {Object} tasks - An object. Each of its properties is either a

- * in the array. The object's key of a property serves as the name of the task
- * defined by that property, i.e. can be used when specifying requirements for
- * other tasks. The function receives one or two arguments:
- * * a `results` object, containing the results of the previously executed
- *   functions, only passed if the task has any dependencies,
- * * a `callback(err, result)` function, which must be called when finished,
- *   passing an `error` (which can be `null`) and the result of the function's
- *   execution.
- * @param {number} [concurrency=Infinity] - An optional `integer` for
- * determining the maximum number of tasks that can be run in parallel. By
- * default, as many as possible.
- * @param {Function} [callback] - An optional callback which is called when all
- * the tasks have been completed. It receives the `err` argument if any `tasks`
- * pass an error to their callback. Results are always returned; however, if an
- * error occurs, no further `tasks` will be performed, and the results object
- * will only contain partial results. Invoked with (err, results).

- * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
- * tasks are specified as parameters to the function, after the usual callback
- * parameter, with the parameter names matching the names of the tasks it
- * depends on. This can provide even more readable task graphs which can be
- * easier to maintain.
- *
- * If a final callback is specified, the task results are similarly injected,
- * specified as named parameters after the initial error parameter.
- *
- * The autoInject function is purely syntactic sugar and its semantics are
- * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
- *
- * @name autoInject
- * @static
- * @memberOf module:ControlFlow
- * @method
- * @see [async.auto]{@link module:ControlFlow.auto}
- * @category Control Flow
- * @param {Object} tasks - An object, each of whose properties is a function of
- * the form 'func([dependencies...], callback). The object's key of a property
- * serves as the name of the task defined by that property, i.e. can be used
- * when specifying requirements for other tasks.
- * * The `callback` parameter is a `callback(err, result)` which must be called
- *   when finished, passing an `error` (which can be `null`) and the result of
- *   the function's execution. The remaining parameters name other tasks on
- *   which the task is dependent, and the results from those tasks are the
- *   arguments of those parameters.
- * @param {Function} [callback] - An optional callback which is called when all
- * the tasks have been completed. It receives the `err` argument if any `tasks`
- * pass an error to their callback, and a `results` object with any completed
- * task results, similar to `auto`.
- * @example
- *
- * //  The example from `auto` can be rewritten as follows:
- * async.autoInject({
- *     get_data: function(callback) {
- *         // async code to get some data
- *         callback(null, 'data', 'converted to array');

- *     make_folder: function(callback) {
- *         // async code to create a directory to store a file in
- *         // this is run at the same time as getting the data
- *         callback(null, 'folder');
- *     },
- *     write_file: function(get_data, make_folder, callback) {
- *         // once there is some data and the directory exists,
- *         // write the data to a file in the directory
- *         callback(null, 'filename');
- *     },
- *     email_link: function(write_file, callback) {
- *         // once the file is written let's email a link to it...
- *         // write_file contains the filename returned by write_file.
- *         callback(null, {'file':write_file, 'email':'user@example.com'});
- *     }
- * }, function(err, results) {
- *     console.log('err = ', err);
- *     console.log('email_link = ', results.email_link);
- * });
- *
- * // If you are using a JS minifier that mangles parameter names, `autoInject`
- * // will not work with plain functions, since the parameter names will be
- * // collapsed to a single letter identifier.  To work around this, you can
- * // explicitly specify the names of the parameters your task function needs
- * // in an array, similar to Angular.js dependency injection.
- *
- * // This still has an advantage over plain `auto`, since the results a task
- * // depends on are still spread into arguments.
- * async.autoInject({

- * Run the `tasks` collection of functions in parallel, without waiting until

- * its callback, the main `callback` is immediately called with the value of the
- * error. Once the `tasks` have completed, the results are passed to the final
- * `callback` as an array.
- *
- * **Note:** `parallel` is about kicking-off I/O tasks in parallel, not about
- * parallel execution of code.  If your tasks do not use any timers or perform
- * any I/O, they will actually be executed in series.  Any synchronous setup
- * sections for each task will happen one after the other.  JavaScript remains
- * single-threaded.
- *
- * It is also possible to use an object instead of an array. Each property will
- * be run as a function and the results will be passed to the final `callback`
- * as an object instead of an array. This can be a more readable way of handling
- * results from {@link async.parallel}.

- * Each function is passed a `callback(err, result)` which it must call on
- * completion with an error `err` (which can be `null`) and an optional `result`
- * value.
- * @param {Function} [callback] - An optional callback to run once all the
- * functions have completed successfully. This function gets a results array
- * (or object) containing all the result arguments passed to the task callbacks.
- * Invoked with (err, results).
- * @example

- * (which can be `null`) and the `result` of the function's execution, and (2)
- * a `results` object, containing the results of the previously executed
- * functions (if nested inside another control flow). Invoked with

- * Run the functions in the `tasks` collection in series, each one running once
- * the previous function has completed. If any functions in the series pass an
- * error to its callback, no more functions are run, and `callback` is
- * immediately called with the value of the error. Otherwise, `callback`
- * receives an array of results when `tasks` have completed.
- *
- * It is also possible to use an object instead of an array. Each property will
- * be run as a function, and the results will be passed to the final `callback`
- * as an object instead of an array. This can be a more readable way of handling
- *  results from {@link async.series}.
- *
- * **Note** that while many implementations preserve the order of object
- * properties, the [ECMAScript Language Specification](http://www.ecma-international.org/ecma-262/5.1/#sec-8.6)
- * explicitly states that
- *
- * > The mechanics and order of enumerating the properties is not specified.
- *
- * So if you rely on the order in which your series of functions are executed,
- * and want this to work on all platforms, consider using an array.

+## API
 
-## CLI
+Returns an `object`, or `false` if color is not supported.
 
-```sh
-$ npm install --global supports-color
-```
+The returned object specifies a level of support for color through a `.level` property and a corresponding flag:
 
-```
-$ supports-color --help
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: 16 million (truecolor) support
 
-  Usage
-    supports-color
 
-  Exits with code 0 if color is supported and 1 if not
-```
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.
+
+Explicit 256/truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
