-# AlaSQL.js - JavaScript SQL database library for relational and graph data manipulation with support of localStorage, IndexedDB, and Excel
-
-AlaSQL - '[à la SQL](http://en.wiktionary.org/wiki/%C3%A0_la)' - is a lightweight JavaScript  SQL database designed to work in browser, Node.js, and Apache Cordova. It supports traditional SQL with some NoSQL functionality. Current version of AlaSQL can work in memory and use file, IndexedDB, and localStorage as a persistent storage.
-
-## How to use?
-
-AlaSQL is easy to use! Just install ```agershun:alasql```packageto your project and call ```alasql()``` function with SQL statement inside: 
-
-```js
-    alasql("CREATE TABLE cities (city string, population number)");
-    alasql("INSERT INTO cities VALUES ('Rome',2863223), ('Paris',2249975),\
-            ('Berlin',3517424), ('Madrid',3041579)");
-    console.log( alasql("SELECT * FROM cities WHERE population < 3500000 ORDER BY population DESC") );
-```

-* [AlaSQL Forum](https://groups.google.com/d/forum/alasql) for discussions
-
-## Documentation 
-
-* [AlaSQL Wiki](https://github.com/agershun/alasql/wiki)
-* [AlaSQL User Manual](http://www.slideshare.net/AndreyGershun/alasql-manual-141220-1)
-* [AlaSQL Coockbok](https://github.com/agershun/alasql/wiki/Data-manipulation) - Q&A, examples
-* [StackOverflow AlaSQL Q&A](http://stackoverflow.com/questions/tagged/alasql)
-
-## Why AlaSQL?
-
-* AlaSQL was written with pure JavaScript and does not use WebSQL database. 
-* AlaSQL uses "good old" SQL with advanced funcionality like multiple JOINs, VIEWs, GROUPs, UNIONs, PRIMARY KEYs, ANY, ALL, IN, subqueries, ROLLUP(), CUBE() and GROUPING SETS(), CROSS APPLY, OUTER APPLY, WITH SELECT, views, functions, variables
-* AlaSQL works with all modern versions of browsers Chrome, Firefox, IE, Safari, Opera, Node.js, and mobile iOS and Android, plus Apache Cordova.
-* AlaSQL can to work directly with JavaScript objects and functions inside SQL, it can search JSON objects like JavaScript and NoSQL databases
-* AlaSQL supports file, IndexedDB, and localStorage (with AUTOCOMMIT ON and AUTOCOMMIT OFF modes)
-* Plus some [JavaScript sugar](#Sugar)
-* AlaSQL is fast, because it uses some optimization methods. 
-
-Check AlaSQL vs other JavaScript SQL databases and data processing libraries: 
-* [AlaSQL vs. WebSQL](http://jsperf.com/alasql-js-vs-websql/7) - for in-memory SELECT operations (see discussion at [issue #47](https://github.com/agershun/alasql/issues/47))
- * [AlaSQL vs. SQL.js](http://jsperf.com/sql-js-vs-alasql-js/4) - in-memory operations* [AlaSQL vs. Linq](http://jsperf.com/alasql-vs-linq-on-groupby) - test on 2^20 records
- * AlaSQL vs. CrossFilter - [test 1](http://jsperf.com/alasql-vs-crossfilter), [test 2 on 8000 records](http://jsperf.com/alasql-vs-crossfilter-athletic-data)
- * [AlaSQL vs. Lodash](http://jsperf.com/alasql-vs-lodash), [AlaSQL vs. Lodash vs. Underscore](http://jsperf.com/alasql-vs-lodash-sort/3) 
- * [AlaSQL vs. Human](http://jsperf.com/javascript-array-grouping/7) :) - based on SatckOverflow [question on grouping](http://stackoverflow.com/questions/6781722/fast-grouping-of-a-javascript-array).
-
-## What is new?
-
-### AlaSQL and Meteor Mongo collections
-
-Now you can use Meteor collections as agruments. To do it simply store alasql.min.js to the client/lib directory and then apply SQL to Meteor Collections: 
-
-```js
-    Template.body.helpers({
-       tasks: function () {
-         return alasql('SELECT * FROM ?',[Tasks]);
-       }
-    });
-```
-
-Or you can use with find() options with special METEOR() from-function:
-```
-    return alasql('SELECT * FROM ?',[Tasks]);
-    return alasql('SELECT * FROM METEOR(?)',[Tasks]);
-    return alasql('SELECT * FROM METEOR(?,?)',[Tasks,{text:"Hello world!"}]);
-    return alasql('SELECT * FROM METEOR(?,{text:"Hello world!"})',[Tasks]);
-```
-
-### Search paths in graph
-
-Now you can search graphs with SEARCH operator:
-```js
-    var res = alasql('CREATE GRAPH Pablo, Maxim, Alex, Napoleon, \
-      Josephine,  Kate, Julia  {age:27}, Paloma, \
-      #Pablo >loves> #Julia, #Maxim >> #Julia, #Alex >> #Kate, \
-      #Kate >> #Julia, #Alex >> #Paloma, #Napoleon > "loves" > #Josephine, \
-      #Josephine >"knows"> #Pablo');
-
-    var res = alasql('SEARCH PATH(#Pablo) name FROM #Napoleon ');
-    // returns ['loves','Josephine','knows','Pablo']
-```
-You can play with grpahs in AlaSQL in [this jsFiddle example](http://jsfiddle.net/fgzya692/1/).
-
-### Documents and graphs paradigms
-
-AlaSQL now is multi-paradigm database with support documents and graphs. Below you can find an example
-how to create graph:
-```js
-    alasql('CREATE GRAPH #Olga, #Helen, #Pablo, #Andrey, #Alice, \
-        #Olga >> #Pablo, #Helen >> #Andrey, \
-        #Pablo >> #Alice, #Andrey >> #Alice');
-```
-and search over it with SEARCH operator:
-```js
-    // Whom loves Olga?
-    alasql('SEARCH / #Olga >> name');
-    // ['Pablo']
-
-    // Whom loves Olga's love objects?
-    alasql('SEARCH / #Olga >> >> name');
-    // ['Alice']
-
-    // Who loves lovers of Alice?
-    alasql('SEARCH / ANY(>> >> #Alice) name');
-    // ['Olga','Helen']
-
-```
-You also make searches over JSON object with SEARCH operator:
-```js
-    var data = {a:{a:{a:{a:{b:10}}}},b:20};
-    var res = alasql('SEARCH a b FROM ?',[data]);
-    var res = alasql('SEARCH (a)+ b FROM ?',[data]);
-    var res = alasql('SEARCH (a a)+ b FROM ?',[data]);
-    var res = alasql('SEARCH (a a a)+ b FROM ?',[data]);
-    var res = alasql('SEARCH (/)+ b FROM ?',[data]);
-    var res = alasql('SEARCH /+b FROM ?',[data]);
-    var res = alasql('SEARCH a* b FROM ?',[data]);
-    var res = alasql('SEARCH a+ b FROM ?',[data]);
-    var res = alasql('SEARCH a? b WHERE(b>20) FROM ?',[data]);
-```
-Please see more examples in test300-test309.js. All these features will be documented soon.
-
-### Version upgrade from 0.0.51 to 0.1.0
-
-AlaSQL now is 6 month old and it can change minor release number from 0.0 to 0.1. 
-
-As we decided earlier, we will change version number to 0.1 after cleaning some 
-known bugs and problems (including [UNION CORRESPONDING](https://github.com/agershun/alasql/issues/75) issue and [IE9 file saving](https://github.com/agershun/alasql/issues/73)). 
-
-The plans and priorities for development from version 0.1 to 0.2 will be:
-* Wiki documentation
-* Fixing bugs and clean the code
-* Add graph- and document- database paradigm functionality
-* Prepare to convert AlaSQL to modular structure (AlaSQL2)
-
-Other areas of future improvements (please add and vote for new features on [Feathub](http://feathub.com/agershun/alasql)):
-* Better Apache Cordova and other mobile frameworks support
-* Improve export to XLS and XLSX (adding colors and LibreOffice support)
-* Support key-value external storages and NoSQL databases
-* Add some missing SQL functionality (constraints, foreign keys, etc.)
-
-### AlaSQL export to Excel with colors (2)
-
-Now AlaSQL can save files to Excel and LibreOffice formats with colors and other
-Excel formatting functions. This function also work in IE9. This is a code sample:
-
-```js
-    var mystyle = {
-      headers:true, 
-      column: {style:{Font:{Bold:"1"}}},
-      rows: {1:{style:{Font:{Color:"#FF0077"}}}},
-      cells: {1:{1:{
-        style: {Font:{Color:"#00FFFF"}}
-      }}}
-    };
-    alasql('SELECT * INTO XLSXML("restest280b.xls",?) FROM ?',[mystyle,data]);
-```
-See the working example in [jsFiddle](http://jsfiddle.net/95j0txwx/7/)
-
-
-### AlaSQL export to Excel with colors (1)
-
-Now AlaSQL can export data to XLS format with coloring cells
-
-```js
-    var opts = {
-      headers: true,
-      sheetid: 'My Birds',
-      style:"background:#00ff00",
-      columns: [
-        {columnid:'a',title:'Albatroses',
-          style:'background:red;font-size:20px',
-          cell:{style:'background:blue'}
-        },
-        {columnid:'b',title:'Bird',cell:{
-          style:function(value,sheet,row,column,rowidx,columnidx){
-            return 'background'+(value==10?'brown':'white')
-        }}},
-        { 
-          columnid: 'b', cell:{value:function(value){ return value * value}}
-        }
-      ]
-    };
-
-    var res = alasql('SELECT * INTO XLS("restest257a.xls",?) FROM ?',[opts,data]); 
-
-```
-Please, see the example with advanced color syntax [in jsFiddle](http://jsfiddle.net/agershun/95j0txwx/2/).
-
-### AlaSQL and Google Spreadsheets (with Tabletop)
-
-Now AlaSQL can read data (and make other manipulations like grouping, filtering, or saving to XLSX) directly from Google Spreadsheets. It uses wonderful [Tabletop library](https://github.com/jsoma/tabletop).
-
-```html
-<script src='../../console/tabletop.js'></script>
-<script src='../../console/alasql.min.js'></script>
-<div id="res"></div>
-<script>
-    var url = 'https://docs.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AmYzu_s7QHsmdDNZUzRlYldnWTZCLXdrMXlYQzVxSFE&output=html';
-
-    alasql('SELECT * INTO HTML("#res",{headers:true}) FROM TABLETOP(?) WHERE name < "D" ORDER BY category',[url]);
-</script>
-```
-
-You can try this example [in jsFiddle](http://jsfiddle.net/ezy7rhhd/2).
-
-### AlaSQL as a WebWorker
-
-AlaSQL can work as a webworker. Include alasql-worker.js and that is it: AlaSQL will work as a webworker.
-
-```html
-    <script src="alasql-worker.min.js"></script>
-    <script>
-        var arr = [{a:1},{a:2},{a:1}];
-        alasql('SELECT * FROM ?',[arr],function(data){
-            console.log(data);
-        });
-    </script>    
-```
-Try the example [at jsFiddle](http://jsfiddle.net/agershun/oxv4rzzc/).
-
-Another option - run alasql.worker() function:
-
-```html
-    <script src="alasql.min.js"></script>
-    <script>
-         alasql.worker();
-         var res = alasql('select value 10',[],function(res){
-              console.log(res);
-         });
-    </script>
-```
-Try this example [in jsFiddle](http://jsfiddle.net/agershun/rjwp8u48/3/).
-
-Also you can use AlaSQL in webworker just simply load it as a script:
-
-```js
-    importScripts('alasql.min.js');
-```
-
-### Read and write Excel, CSV, TAB, JSON,  and text files to/from database
-
-Now AlaSQL can work with files in XLS, XSLX, CSV, TAB, TXT, and JSON format
-
-```js
-    alasql('select * into one from csv("mydata.csv")');
-    alasql('select Country, Name from xlsx("cities.xlsx",{headers:true, range:"B1:E10"})\
-        where Population > 100000',
-        [],function(data){
-        console.log(data);
-    });
-```
-See [test168](test/test168.js) - [test169](test/test169.js)
-
-### d3.js + AlaSQL
-
-AlaSQL can be used with d3.js to create diagrams, like the example below. Here AlaSQL
-read Excel file with Olympic Prizes, group and sort rows by one of the axes, and then
-take top 10 records and create a list with axe values:
-
-```js
-    function graph(axe) {
-        alasql('SELECT TOP 10 '+axe+', SUM([Gold Medals]) AS Gold, \
-            SUM([Silver Medals]) AS Silver, SUM([Bronze Medals]) AS Bronze \
-            FROM XLSX("medals.xlsx",{headers:true}) \
-            GROUP BY '+axe+' ORDER BY '+axe,[],function(data){
-
-            d3.select("body")
-            .append('ul')
-            .data(data)
-            .entry()
-            .append('li')
-            .text(function(d){return d[axe]});
-        });
-    }
-
-    graph('Axe');
-
-```
-
-Try the [simple example](http://alasql.org/demo/005d3/) of AlaSQL + d3.js integration.
-
-
-### Google Maps + AlaSQL
-```js
-    alasql("SELECT * FROM CSV("https://cdn.rawgit.com/albertyw/avenews/master/old/data/average-latitude-longitude-countries.csv",{headers:true})', [], function(country){
-        var mapOptions = { zoom : 3, center : new google.maps.LatLng(40, 0),
-            mapTypeId : google.maps.MapTypeId.ROADMAP
-        };
-        var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
-        for (i = 0; i < country.length; i++) {
-            var opts = {
-                strokeColor : '#000000',
-                fillColor : ["red","green","blue","brown"][i%4],
-                fillOpacity : 0.35,
-                map : map,
-                center : new google.maps.LatLng(country[i].Latitude,country[i].Longitude),
-                radius : 100000
-            };
-            new google.maps.Circle(opts);
-    });
-```
-Check [this example](http://alasql.org/demo/009geo) and [this example](http://jsfiddle.net/agershun/1o2xq1yh/2/) of integrations AlaSQL and Google Maps.
-
-### ETL sample: CSV and IndexedDB database
-
-Upload CSV file with headers to IndexedDB database, and then save only asian countries 
-to Excel file:
-```js
-    alasql('ATTACH INDEXEDDB DATABASE geo; \
-            CREATE TABLE IF NOT EXISTS geo.country; \
-            SELECT * INTO geo.country FROM CSV("country.csv",{headers:true}); \
-            SELECT * INTO XLSX("asia.xlsx") FROM geo.country WHERE continent_name = "Asia"');
-```
-See [the example](http://alasql.org/demo/001csv/). 
-
-### Read SQLite database files
-
-AlaSQL can work with SQLite data files on the top of with [SQL.js](https://github.com/kripken/sql.js) library:
-```html
-    <script src="alasql.js"></script>
-    <script src="sql.js"></script>
-    <script>
-        alasql('ATTACH SQLITE DATABASE Chinook("Chinook_Sqlite.sqlite");\
-            USE Chinook; \
-            SELECT * FROM Genre',[],function(res){
-                console.log("Genres:",res.pop());
-        });
-    </script>
-```
-
-See more detailed [the example](http://alasql.org/demo/004sqlite/).
-
-### Angular.js and AlaSQL.js
-
-You can use AlaSQL together with Angular.js framework:
-
-```js
-    $scope.exportData = function () {

-
-## Installation
-
-### In browser
-
-Include file: [alasql.js](./alasql.js) to the page.
-
-```html
-  <script src="alasql.js"></script>  
-  <script>
-    alasql("CREATE TABLE test (language INT, hello STRING)");
-    alasql("INSERT INTO test VALUES (1,'Hello!')");
-    alasql("INSERT INTO test VALUES (2,'Aloha!')");
-    alasql("INSERT INTO test VALUES (3,'Bonjour!')");
-    console.table(alasql("SELECT * FROM test WHERE language > 1"));
-  </script>
-
-```
-Try this sample in [AlaSQL console](http://alasql.org/console?CREATE TABLE test (language INT, hello STRING);INSERT INTO test VALUES (1,'Hello!');INSERT INTO test VALUES (2,'Aloha!');INSERT INTO test VALUES (3,'Bonjour!');SELECT * FROM test WHERE language > 1)
-
-You can use alasql.js with define()/require() functions in browser as well, because it supports AMD and UMD:
-
-```js
-    require(['../../alasql.js'], function(alasql) {
-        var test1 = [{a:1,b:2,c:3},{a:4,b:5,c:6},{a:7,b:8,c:9}];
-        console.table(alasql('SELECT a, b*c AS bc FROM ? AS t',[test1]));
-    });
-```
-Like in this sample you do not need to CREATE TABLE and INSERTS if you do not need constraints functionality.
-
-### In Node.js
-
-Use the following command for installation:
-```
-    npm install alasql
-```
-Then require alasql.js file:
-
-```js
-    var alasql = require('alasql');
-
-    var db = new alasql.Database();
-    
-    db.exec("CREATE TABLE test (one INT, two INT)");
-    db.tables.test.data = [   // You can mix SQL and JavaScript
-        {one:3,two:4},
-        {one:5,two:6},
-    ];
-    var res = db.exec("SELECT * FROM test ORDER BY two DESC");
-    console.log(res[0].one);
-
-```
-
-### Supported SQL statements
-
-* SELECT TOP number columns INTO table FROM tableid1 JOIN tableid2 ON oncond WHERE cond GROUP BY v1,v2 HAVING cond ORDER BY a,b, LIMIT number OFFSET number
-* INSERT INTO table \[ (field1, field2) \] VALUES (value1, value2), (value3, value4), ...
-* INSERT INTO table SELECT subquery
-* UPDATE table SET field = value1, field = value2 WHERE condition 
-* DELETE FROM table WHERE condition 
-* CREATE TABLE \[IF NOT EXISTS\] table (columns type PRIMARY KEY, constraints)
-* ALTER TABLE ADD COLUMN / DROP COLUMN
-* DROP TABLE \[IF EXISTS\] table
-* CREATE DATABASE, USE DATABASE, DROP DATABASE
-* SHOW DATABASES / SHOW TABLES / SHOW COLUMNS / SHOW CREATE TABLE
-* SOURCE 'url-file.sql'
-* ASSERT json-object
-* Expression (like SELECT expression)
-
-Try all these statements in [AlaSQL console](http://alasql.org/console?help)
-
-#### SELECT statement
-
-AlaSQL.js supports following subset of SELECT syntax:
-
-* SELECT column1, column2 AS alias3, FUNCTION(field4+field5) AS alias6, SUM(expression7) AS alias8, *, table2.*
-* TOP number
-* FROM table1, table2, (SELECT * FROM table3) alias
-* LEFT / RIGHT / INNER / OUTER / ANTI / SEMI / CROSS / NATURAL JOIN table2 ON condition / USING columns
-* WHERE condition
-* GROUP BY column1, column2, ROLLUP(a,b), CUBE(c,d,e), GROUPING SETS(g,h)
-* HAVING condition
-* ORDER BY column1, column2 DESC, 
-* LIMIT number [OFFSET number]
-* UNION / UNION ALL select / INTERSECT / EXCEPT
-
-Operators:
-
-* +, -, *, /, %, AND, OR, NOT, BETWEEN, NOT BETWEEN, EXISTS (Subquery), > ALL (subquery/array), > ANY/SOME (subquery / array), [NOT] IN (subquery / array), LIKE
-* CAST (expression AS type)
-
-Aggregators:
-
-* SUM(), COUNT(), MIN(), MAX(), FIRST(), LAST(), AVG(), AGGR(), ARRAY(), REDUCE()
-
-GROUP BY Grouping functions:
-
-* ROLLUP(), CUBE(), GROUPING SETS()
-
-Functions:
-
-* ABS(), IIF(), IFNULL(), INSTR(), LOWER(), UPPER(), LCASE(), UCASE(), LEN(), LENGTH()
-* GREATEST(), LEAST()
-
-SELECT modifiers (non-standard SQL):
-* SELECT VALUE - get single value
-* SELECT ROW - get first row as an array
-* SELECT COLUMN - get first column as an array
-* SELECT MATRIX - get all results as an array of arrays
-
-#### User-defined JavaScript functions
-
-You can use all benefits of SQL and JavaScript togeather by defining user functions. Just add new functions to alasql.fn object:
-
-```js
-        alasql.fn.double = function(x){return x*2};        
-        alasql.fn.sum10 = function(x,y) { return x+y*10; }
-        db.exec('SELECT a, double(a) AS b, sum10(a,b) FROM test1');
-```
-
-User-defined functions are related to current database. You can define different functions in different databases. 
-
-### alasql
-
-alasql is a main variable of module. You can use it immediatly as default database
-
-In browser:
-```html
-    <script src="alasql.js"></script>
-    <script>
-        alasql('CREATE TABLE one (two INT)');
-    </script>
-```
-Try this sample in [AlaSQL console](http://alasql.org/console?CREATE TABLE one (two INT))
-
-
-or in Node.js:
-```js
-    var alasql = require('alasql');
-    alasql('CREATE TABLE one (two INT)');
-```
-
-Another approach is to create new database:
-
-```js
-    var mybase = new alasql.Database();
-    mybase.exec('CREATE TABLE one (two INT)');
-```
-You can give a name to database and then access it from alasql:
-```js
-    var mybase = new alasql.Database('mybase');
-    console.log(alasql.databases.mybase);
-```
-
-Each database can be used with the following methods:
-
-```js
-    var db = new alasql.Database() - create new alasql-database
-    var res = db.exec("SELECT * FROM one") - executes SELECT query and returns array of objects 
-```
-
-Usually, alasql.js works synchronously, but you can use callback.
-
-```js
-    db.exec('SELECT * FROM test', [], function(res){
-    	console.log(res);
-    });
-```
-
-or you can use aexec() - promised version of exec (in this case you need to install [es6-promise](https://www.npmjs.org/package/es6-promise) module for Node.js) (this feature is experimental and may be removed in a future to reduce dependices):
-```js
-    db.aexec('SELECT * FROM test').then(function(res){
-        console.log(res);
-    });
-```
-You can use compile statements:
-```js
-    var insert = db.compile('INSERT INTO one (1,2)');
-    insert();
-```
-
-You can use parameters in compiled and interpreted statements:
-
-```js
-    var insert1 = db.compile('INSERT INTO one (?,?)');
-    var insert2 = db.compile('INSERT INTO one ($a,$b)');
-    var insert3 = db.compile('INSERT INTO one (:a,:b)');
-
-    insert1([1,2]);
-    insert2({a:1,b:2});
-    insert3({a:3,b:4});
-
-    db.exec('INSERT INTO one (?,?)',[5,6]);
-
-```
-You even can use param in FROM clause: 
-
-```js
-        var years = [
-            {yearid: 2012}, {yearid: 2013},
-            {yearid: 2014}, {yearid: 2015},
-            {yearid: 2016},
-        ];
-
-        var res = alasql.queryArray('SELECT * FROM ? AS years ' +
-            'WHERE yearid > ?', [years,2014]);
-
-        // res == [2015,2016]
-```
-You can use array of arrays to make a query. In this case use square brackets for column name,
-like \[1\] or table\[2\] (remember, all arrays in JavaScript start with 0):
-```js
-        var data = [
-            [2014, 1, 1], [2015, 2, 1],
-            [2016, 3, 1], [2017, 4, 2],
-            [2018, 5, 3], [2019, 6, 3]
-        ];
-        var res = alasql('SELECT SUM([1]) FROM ? d WHERE [0]>2016', [data]);
-```
-Use alasql.queryArrayOfArrays() function to return array of arrays. In this case
-you can specify array position of selected column with number or number in brackets:
-```js
-        var res = alasql.queryArrayOfArrays(
-            'SELECT [1] AS 0,[1]+[2] AS [1] FROM ? d WHERE [0]>2016', [data]);
-```
-This feature can be used as filter for arrays. Compare:
-```js
-        // Same filter
-        var res1 = alasql.queryArrayOfArrays('SELECT * FROM ? a WHERE [0]>2016', [data]);
-        var res2 = data.filter(function(a){return a[0]>2016});
-
-        // Complex filter with aggregating, grouping and sorting
-        var res = alasql.queryArrayOfArrays(
-            'SELECT [2] AS 0, SUM([1]) AS 1 FROM ? a WHERE a[0]>? GROUP BY [0] ORDER BY [1]', 
-            [data, 2016]);
-
-```
-
-### Lower and Upper Case
-
-By default, AlaSQL is case-insensitive to all standard keywords (like SELECT) and standard functions (like ABS()). All database names, table names, column names, and user-defined functions are case sensitive. 
-
-JavaScript is case-sensitive language, so use the same CaSe for AlaSQL and JavaScript data.
-
-Now you can use databases, tables, and columns with spaces inside square brackets:
-
-```sql
-    CREATE DATABASE [My Database];  -- BTW You can use comments in the SQL statements
-    USE [My Database];              /* or comments like this */   
-    CREATE TABLE [A.table] ([the-column] INT);
-    INSERT INTO [A.table] VALUES (1),(2);
-    SELECT [the-column] AS [AS] FROM [My Database];
-```
-Try this sample in [AlaSQL console](http://alasql.org/console?CREATE DATABASE [My Database];USE [My Database];CREATE TABLE [A.table] ([the-column] INT);INSERT INTO [A.table] VALUES (1),(2);SELECT [the-column] AS [AS] FROM [My Database])
-
-
-### JavaScript Sugar
-
-AlaSQL extends "good old" SQL to make it closer to JavaScript. The "sugar" includes:
-
-* Json objects - ``` {a:1,b:@[1,2,3]}
-* Object propertires - ```obj->property->subproperty```
-* Object and arrays elements - ```obj->(a*1)```
-* JavaScript functions - ```obj->valueOf()```
-* SELECT VALUE, ROW, COLUMN, MATRIX to format results of query
-
-### Transactions
-
-There is a limited support of transactions (with tx.rollback() and tx.commit() functions):
-
-```js
-    db = new alasql.Database("mydb");
-    db.transaction(function(tx) {
-        tx.exec('SELECT COUNT(*) FROM students');
-        tx.rollback();
-    });     
-
-```
-Warning: Sorry, transactions now are temporary unavailable due some complexities with realization.
-
-### SQL to JavaScript parser and compiler
-
-You can use AlaSQL to parse to AST and compile SQL statements:
-
-```js
-    // Parse to AST
-    var ast = alasql.parse("SELECT * FROM one");
-    console.log(ast.toString()); // Print restored SQL statement
-
-    // Compile to JavaScript function with or without parameters
-    var statement = alasql.compile("SELECT * FROM one WHERE a > ? AND b < ?");
-    statement([1,5]);
-```
-
-AlaSQL uses wonderful [Jison](http://jison.org) parser to produce AST-tree.
-
-
-### localStorage and DOM-storage
-You can use browser localStorage and [DOM-storage](https://github.com/node-browser-compat/dom-storage) as a data storage. Here is a sample:
-```
-    alasql('CREATE localStorage DATABASE IF NOT EXISTS Atlas');
-    alasql('ATTACH localStorage DATABASE Atlas AS MyAtlas');
-    alasql('CREATE TABLE IF NOT EXISTS MyAtlas.City (city string, population number)');
-    alasql('SELECT * INTO MyAtlas.City FROM ?',[[{city:'Vienna', population:1731000}, 
-        {city:'Budapest', population:1728000}]]);
-    var res = alasql('SELECT * FROM MyAtlas.City');
-    console.log(res);
-```
-Try this sample in [jsFiddle](http://jsfiddle.net/agershun/x1gq3wf2/). Run this sample 
-two or three times, and AlaSQL store more and more data in localStorage. Here, "Atlas" is 
-the name of localStorage database, where "MyAtlas" is a memory AlaSQL database.
-
-You can use localStorage in two modes: SET AUTOCOMMIT ON to immediate save data
-to localStorage after each statement or SET AUTOCOMMIT OFF. In this case you need
-to use COMMIT statement to save all data from in-memory mirror to localStorage.
-
-### Work with CSV, TAB, TXT, and JSON files
-You can use files in these formats directly from AlaSQL (in sync and async modes):
-```js
-    var res1 = alasq("select * from txt('mytext.txt') where [0] like 'M%'");
-    var res2 = alasq("select * from tab('mydata.tab') order by [1]");
-    var res3 = alasq("select [3] as city,[4] as population from csv('cities.csv')");
-    
-    alasq("select * from json('array.json')",[],function(res4){
-        console.log(res4)
-    });
-```
-See [test157.js](test/test157.js) as an example.
-
-### JSON-objects
-
-You can use JSON objects in your databases (do not forget use == and !== operators for deep comparision of objects):
-```sql
-    alasql> SELECT VALUE @{a:1,b:2}
-
-    {a:1,b:2}
-
-    alasql> SELECT VALUE @{a:1,b:2} == @{a:1,b:2}
-
-    true
-
-    alasql> SELECT VALUE @{a:1,b:2}->b
-
-    2
-
-    alasql> SELECT VALUE @{a:1,b:(2*2)}->b
-
-    4
-
-```
-Try AlaSQL JSON objects in  Console [sample](http://alasql.org/console?drop table if exists one;create table one;insert into one values @{a:@[1,2,3],c:{e:23}}, @{a:@[{b:@[1,2,3]}]};select * from one)
-
-### Alacon - command-line utility
-
-You can use AlaSQL from the command-line:
-```sql
-    > alacon "SELECT VALUE 1+1"
-    2
-    > alacon "SELECT VALUE 1+?" 2
-    3
-    > alacon "@{a:(1+?)}" 3
-    4
-```
-
-### Alaserver - simple database server
-
-Yes, you can even use AlaSQL as a very simple server for tests.
-
-To run enter the command: 
-```
-    alaserver [port]
-```
-then type in browser something like "http://127.0.0.1:1337/?SELECT VALUE 2*2" 
-
-Warning: Alaserver is not multi-thread, not concurent, and not secured.
-
-
-### Performance
-
-According the preliminary performance tests alasql.js is faster than [sql.js]() in 5 to 10 times on more than 1000 records tables, and 2 to 3 times to [WebSQL]() on different queries. 
-
-AlaSQL has four different optimization algorithm:
-* Caching of compiled queries
-* Joins: Preindexation of joined table
-* Joins: Prefiltering of WHERE expressions
-
-Now optimization algorithm has some limitations and therefore "table1 JOIN table2 USING column1, column2" is faster than "table1 JOIN table2 ON table1.column1 = table2.column1 AND table1.column2 = table2.column2 ", but with one column it is ok.
-
-### Limitations
-
-It is Ok with select for 1000000 records or 2 join two tables by 10000 records in each. 
-Now you can use streamming functions to work with longer datasources (see [test/test143.js](test/test143.js).
-
-### Tests
-
-### Tests with Mocha
-AlaSQL uses ```mocha``` for tests. Run mocha from command line in directory with tests:
-
-```
-    > cd test
-    > mocha .
-```
-or run [test/index.html](test/index.html) for tests in browser.
-
-### Tests with AlaSQL ASSERT from SQL
-
-Now you can use AlaSQL [ASSERT](wiki/Assert)  operator to test results of previous operation:
-```sql
-    CREATE TABLE one (a INT);
-    ASSERT 1;
-    INSERT INTO one VALUES (1),(2),(3);
-    ASSERT 3;
-    SELECT * FROM one ORDER BY a DESC;
-    ASSERT [{a:3},{a:2},{a:1}];
-```
-
-### Warnings 
-AlaSQL project is very young and still in active development phase, therefore it may have some bugs. Please, wait a little bit before start to use it in production. I am going to add more tests and clean the code before relaese more stable version 0.1.0. Please, submit any bugs and suggestions in [Issues page](https://github.com/agershun/alasql/issues).
-
-You can check next version branches for new experimental features. 
-
-### Known Bugs and Limitations
-
-1. ORDER BY clause on three or more UNIONS ( [See example in AlaSQL console](http://alasql.org/console?select 10 as a union all select 20 as a union all select 30 as a order by a desc) )
-2. Limited functionality for transactions (supports only for localStorage) - Sorry, transactions are limited, because AlaSQL started to use more complex approach for PRIMARY KEYS / FOREIGN KEYS. Transactions will be fully turned on again in one of the future version.
-
-
-Probably, there are many of others. Please, [give me a chance](https://github.com/agershun/alasql/issues) to fix them. Thank you!

-# ES6-Promises (subset of [rsvp.js](https://github.com/tildeio/rsvp.js))
-
-This is a polyfill of [ES6 Promises](https://github.com/domenic/promises-unwrapping). The implementation is a subset of [rsvp.js](https://github.com/tildeio/rsvp.js), if you're wanting extra features and more debugging options, check out the [full library](https://github.com/tildeio/rsvp.js).
-
-For API details and how to use promises, see the <a href="http://www.html5rocks.com/en/tutorials/es6/promises/">JavaScript Promises HTML5Rocks article</a>.

-## Downloads
-
-* [promise](http://s3.amazonaws.com/es6-promises/promise-1.0.0.js)
-* [promise-min](http://s3.amazonaws.com/es6-promises/promise-1.0.0.min.js) (~2k gzipped)
-
-## Node.js
-
-To install:
-
-```sh
-npm install es6-promise
-```
-
-To use:
-
-```js
-var Promise = require('es6-promise').Promise;
-```
-
-## Usage in IE<10
-
-`catch` is a reserved word in IE<10, meaning `promise.catch(func)` throws a syntax error. To work around this, to a string to access the property:
-
-```js
-promise['catch'](function(err) {
-  // ...
-});
-```
-
-Or use `.then` instead:
-
-```js
-promise.then(undefined, function(err) {
-  // ...
-});
-```
-
-## Building & Testing
-
-This package uses the [grunt-microlib](https://github.com/thomasboyt/grunt-microlib) package for building.
-
-Custom tasks:
-
-* `grunt test` - Run Mocha tests through Node and PhantomJS.
-* `grunt test:phantom` - Run Mocha tests through PhantomJS (browser build).
-* `grunt test:node` - Run Mocha tests through Node (CommonJS build).

+# ES6-Promise (subset of [rsvp.js](https://github.com/tildeio/rsvp.js))
+
+This is a polyfill of the [ES6 Promise](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-constructor). The implementation is a subset of [rsvp.js](https://github.com/tildeio/rsvp.js), if you're wanting extra features and more debugging options, check out the [full library](https://github.com/tildeio/rsvp.js).

+* [es6-promise-min](https://raw.githubusercontent.com/jakearchibald/es6-promise/master/dist/es6-promise-min.js)
+
+## Node.js
+
+To install:
+
+```sh
+npm install es6-promise
+```
+
+To use:
+
+```js
+var Promise = require('es6-promise').Promise;
+```
+
+## Usage in IE<9
+
+`catch` is a reserved word in IE<9, meaning `promise.catch(func)` throws a syntax error. To work around this, you can use a string to access the property as shown in the following example.
+
+However, please remember that such technique is already provided by most common minifiers, making the resulting code safe for old browsers and production:
+
+```js
+promise['catch'](function(err) {
+  // ...
+});
+```
+
+Or use `.then` instead:
+
+```js
+promise.then(undefined, function(err) {
+  // ...
+});
+```
+
+## Auto-polyfill
+
+To polyfill the global environment (either in Node or in the browser via CommonJS) use the following code snippet:
+
+```js
+require('es6-promise').polyfill();
+```
+
+Notice that we don't assign the result of `polyfill()` to any variable. The `polyfill()` method will patch the global environment (in this case to the `Promise` name) when called.
+
+## Building & Testing
+
+* `npm run build` to build
+* `npm test` to run tests
+* `npm start` to run a build watcher, and webserver to test 
+* `npm run test:server` for a testem test runner and watching builder

-/**
-  Returns a promise that is fulfilled when all the given promises have been
-  fulfilled, or rejected if any of them become rejected. The return promise
-  is fulfilled with an array that gives all the values in the order they were
-  passed in the `promises` array argument.
-
-  Example:
-
-  ```javascript
-  var promise1 = RSVP.resolve(1);
-  var promise2 = RSVP.resolve(2);
-  var promise3 = RSVP.resolve(3);
-  var promises = [ promise1, promise2, promise3 ];
-
-  RSVP.all(promises).then(function(array){
-    // The array here would be [ 1, 2, 3 ];
-  });
-  ```
-
-  If any of the `promises` given to `RSVP.all` are rejected, the first promise
-  that is rejected will be given as an argument to the returned promises's
-  rejection handler. For example:
-
-  Example:
-
-  ```javascript
-  var promise1 = RSVP.resolve(1);
-  var promise2 = RSVP.reject(new Error("2"));
-  var promise3 = RSVP.reject(new Error("3"));
-  var promises = [ promise1, promise2, promise3 ];
-
-  RSVP.all(promises).then(function(array){
-    // Code here never runs because there are rejected promises!
-  }, function(error) {
-    // error.message === "2"
-  });
-  ```
-
-  @method all
-  @for RSVP
-  @param {Array} promises
-  @param {String} label
-  @return {Promise} promise that is fulfilled when all `promises` have been
-  fulfilled, or rejected if any of them become rejected.

-  `RSVP.race` allows you to watch a series of promises and act as soon as the
-  first promise given to the `promises` argument fulfills or rejects.
-
-  Example:
-
-  ```javascript
-  var promise1 = new RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      resolve("promise 1");
-    }, 200);
-  });
-
-  var promise2 = new RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){

-    }, 100);
-  });
-
-  RSVP.race([promise1, promise2]).then(function(result){
-    // result === "promise 2" because it was resolved before promise1
-    // was resolved.
-  });
-  ```
-
-  `RSVP.race` is deterministic in that only the state of the first completed
-  promise matters. For example, even if other promises given to the `promises`
-  array argument are resolved, but the first completed promise has become
-  rejected before the other promises became fulfilled, the returned promise
-  will become rejected:
-
-  ```javascript
-  var promise1 = new RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      resolve("promise 1");
-    }, 200);
-  });
-
-  var promise2 = new RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      reject(new Error("promise 2"));
-    }, 100);
-  });
-
-  RSVP.race([promise1, promise2]).then(function(result){
-    // Code here never runs because there are rejected promises!
-  }, function(reason){
-    // reason.message === "promise2" because promise 2 became rejected before
-    // promise 1 became fulfilled
-  });
-  ```
-
-  @method race
-  @for RSVP
-  @param {Array} promises array of promises to observe
-  @param {String} label optional string for describing the promise returned.
-  Useful for tooling.
-  @return {Promise} a promise that becomes fulfilled with the value the first

-/**
-  `RSVP.reject` returns a promise that will become rejected with the passed
-  `reason`. `RSVP.reject` is essentially shorthand for the following:
-
-  ```javascript
-  var promise = new RSVP.Promise(function(resolve, reject){
-    reject(new Error('WHOOPS'));
-  });
-
-  promise.then(function(value){
-    // Code here doesn't run because the promise is rejected!
-  }, function(reason){
-    // reason.message === 'WHOOPS'
-  });
-  ```
-
-  Instead of writing the above, your code now simply becomes the following:
-
-  ```javascript
-  var promise = RSVP.reject(new Error('WHOOPS'));
-
-  promise.then(function(value){
-    // Code here doesn't run because the promise is rejected!
-  }, function(reason){
-    // reason.message === 'WHOOPS'
-  });
-  ```
-
-  @method reject
-  @for RSVP
-  @param {Any} reason value that the returned promise will be rejected with.
-  @param {String} label optional string for identifying the returned promise.
-  Useful for tooling.
-  @return {Promise} a promise that will become rejected with the given
-  `reason`.

+      Promise objects represent the eventual result of an asynchronous operation. The
+      primary way of interacting with a promise is through its `then` method, which
+      registers callbacks to receive either a promise’s eventual value or the reason
+      why the promise cannot be fulfilled.
+
+      Terminology
+      -----------
+
+      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+      - `thenable` is an object or function that defines a `then` method.
+      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+      - `exception` is a value that is thrown using the throw statement.
+      - `reason` is a value that indicates why a promise was rejected.
+      - `settled` the final resting state of a promise, fulfilled or rejected.
+
+      A promise can be in one of three states: pending, fulfilled, or rejected.
+
+      Promises that are fulfilled have a fulfillment value and are in the fulfilled
+      state.  Promises that are rejected have a rejection reason and are in the
+      rejected state.  A fulfillment value is never a thenable.
+
+      Promises can also be said to *resolve* a value.  If this value is also a
+      promise, then the original promise's settled state will match the value's
+      settled state.  So a promise that *resolves* a promise that rejects will
+      itself reject, and a promise that *resolves* a promise that fulfills will
+      itself fulfill.
+
+
+      Basic Usage:
+      ------------
+
+      ```js
+      var promise = new Promise(function(resolve, reject) {
+        // on success
+        resolve(value);
+
+        // on failure
+        reject(reason);
+      });
+
+      promise.then(function(value) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Advanced Usage:
+      ---------------
+
+      Promises shine when abstracting away asynchronous interactions such as
+      `XMLHttpRequest`s.
+
+      ```js
+      function getJSON(url) {
+        return new Promise(function(resolve, reject){
+          var xhr = new XMLHttpRequest();
+
+          xhr.open('GET', url);
+          xhr.onreadystatechange = handler;
+          xhr.responseType = 'json';
+          xhr.setRequestHeader('Accept', 'application/json');
+          xhr.send();
+
+          function handler() {
+            if (this.readyState === this.DONE) {
+              if (this.status === 200) {
+                resolve(this.response);
+              } else {
+                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+              }
+            }
+          };
+        });
+      }
+
+      getJSON('/posts.json').then(function(json) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Unlike callbacks, promises are great composable primitives.
+
+      ```js
+      Promise.all([
+        getJSON('/posts'),
+        getJSON('/comments')
+      ]).then(function(values){
+        values[0] // => postsJSON
+        values[1] // => commentsJSON
+
+        return values;
+      });
+      ```
+
+      @class Promise
+      @param {function} resolver
+      Useful for tooling.
+      @constructor
+    */
+    function lib$es6$promise$promise$$Promise(resolver) {
+      this._id = lib$es6$promise$promise$$counter++;
+      this._state = undefined;
+      this._result = undefined;
+      this._subscribers = [];
+
+      if (lib$es6$promise$$internal$$noop !== resolver) {
+        if (!lib$es6$promise$utils$$isFunction(resolver)) {
+          lib$es6$promise$promise$$needsResolver();
+        }
+
+        if (!(this instanceof lib$es6$promise$promise$$Promise)) {
+          lib$es6$promise$promise$$needsNew();
+        }
+
+        lib$es6$promise$$internal$$initializePromise(this, resolver);
+      }
+    }
+
+    lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default;
+    lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default;
+    lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default;
+    lib$es6$promise$promise$$Promise.reject = lib$es6$promise$promise$reject$$default;
+
+    lib$es6$promise$promise$$Promise.prototype = {
+      constructor: lib$es6$promise$promise$$Promise,
+
+    /**
+      The primary way of interacting with a promise is through its `then` method,
+      which registers callbacks to receive either a promise's eventual value or the
+      reason why the promise cannot be fulfilled.
+
+      ```js
+      findUser().then(function(user){
+        // user is available
+      }, function(reason){
+        // user is unavailable, and you are given the reason why
+      });
+      ```
+
+      Chaining
+      --------
+
+      The return value of `then` is itself a promise.  This second, 'downstream'
+      promise is resolved with the return value of the first promise's fulfillment
+      or rejection handler, or rejected if the handler throws an exception.
+
+      ```js
+      findUser().then(function (user) {
+        return user.name;
+      }, function (reason) {
+        return 'default name';
+      }).then(function (userName) {
+        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+        // will be `'default name'`
+      });
+
+      findUser().then(function (user) {
+        throw new Error('Found user, but still unhappy');
+      }, function (reason) {
+        throw new Error('`findUser` rejected and we're unhappy');
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+      });
+      ```
+      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+      ```js
+      findUser().then(function (user) {
+        throw new PedagogicalException('Upstream error');
+      }).then(function (value) {
+        // never reached
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // The `PedgagocialException` is propagated all the way down to here
+      });
+      ```
+
+      Assimilation
+      ------------
+
+      Sometimes the value you want to propagate to a downstream promise can only be
+      retrieved asynchronously. This can be achieved by returning a promise in the
+      fulfillment or rejection handler. The downstream promise will then be pending
+      until the returned promise is settled. This is called *assimilation*.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // The user's comments are now available
+      });
+      ```
+
+      If the assimliated promise rejects, then the downstream promise will also reject.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // If `findCommentsByAuthor` fulfills, we'll have the value here
+      }, function (reason) {
+        // If `findCommentsByAuthor` rejects, we'll have the reason here
+      });
+      ```

+
+      Synchronous Example
+
+      ```javascript
+      var result;
+
+      try {

-      Returns a promise that is fulfilled when all the given promises have been
-      fulfilled, or rejected if any of them become rejected. The return promise
-      is fulfilled with an array that gives all the values in the order they were
-      passed in the `promises` array argument.
-
-      Example:
-
-      ```javascript
-      var promise1 = RSVP.resolve(1);
-      var promise2 = RSVP.resolve(2);
-      var promise3 = RSVP.resolve(3);

-      RSVP.all(promises).then(function(array){
-        // The array here would be [ 1, 2, 3 ];
-      });
-      ```
-
-      If any of the `promises` given to `RSVP.all` are rejected, the first promise
-      that is rejected will be given as an argument to the returned promises's
-      rejection handler. For example:
-
-      Example:
-
-      ```javascript
-      var promise1 = RSVP.resolve(1);
-      var promise2 = RSVP.reject(new Error("2"));
-      var promise3 = RSVP.reject(new Error("3"));
-      var promises = [ promise1, promise2, promise3 ];
-

-      `RSVP.race` allows you to watch a series of promises and act as soon as the
-      first promise given to the `promises` argument fulfills or rejects.
-
-      Example:
-
-      ```javascript
-      var promise1 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 1");

-        // was resolved.
-      });
-      ```
-
-      `RSVP.race` is deterministic in that only the state of the first completed
-      promise matters. For example, even if other promises given to the `promises`
-      array argument are resolved, but the first completed promise has become
-      rejected before the other promises became fulfilled, the returned promise
-      will become rejected:
-
-      ```javascript
-      var promise1 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 1");
-        }, 200);
-      });
-
-      var promise2 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          reject(new Error("promise 2"));
-        }, 100);
-      });
-
-      RSVP.race([promise1, promise2]).then(function(result){
-        // Code here never runs because there are rejected promises!
-      }, function(reason){
-        // reason.message === "promise2" because promise 2 became rejected before
-        // promise 1 became fulfilled
-      });
-      ```
-

-      @for RSVP
-      @param {Array} promises array of promises to observe
-      @param {String} label optional string for describing the promise returned.

-      `RSVP.race` allows you to watch a series of promises and act as soon as the
-      first promise given to the `promises` argument fulfills or rejects.
-
-      Example:
-
-      ```javascript
-      var promise1 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 1");
-        }, 200);

-
-      var promise2 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){

-        }, 100);
-      });
-
-      RSVP.race([promise1, promise2]).then(function(result){
-        // result === "promise 2" because it was resolved before promise1
-        // was resolved.
-      });
-      ```
-
-      `RSVP.race` is deterministic in that only the state of the first completed
-      promise matters. For example, even if other promises given to the `promises`
-      array argument are resolved, but the first completed promise has become
-      rejected before the other promises became fulfilled, the returned promise
-      will become rejected:
-
-      ```javascript
-      var promise1 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 1");
-        }, 200);
-      });
-
-      var promise2 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          reject(new Error("promise 2"));
-        }, 100);
-      });
-
-      RSVP.race([promise1, promise2]).then(function(result){
-        // Code here never runs because there are rejected promises!
-      }, function(reason){
-        // reason.message === "promise2" because promise 2 became rejected before
-        // promise 1 became fulfilled
-      });
-      ```
-
-      @method race
-      @for RSVP
-      @param {Array} promises array of promises to observe
-      @param {String} label optional string for describing the promise returned.
-      Useful for tooling.
-      @return {Promise} a promise that becomes fulfilled with the value the first
-      completed promises is resolved with if the first completed promise was
-      fulfilled, or rejected with the reason that the first completed promise
-      was rejected with.

+      Promise objects represent the eventual result of an asynchronous operation. The
+      primary way of interacting with a promise is through its `then` method, which
+      registers callbacks to receive either a promise’s eventual value or the reason
+      why the promise cannot be fulfilled.
+
+      Terminology
+      -----------
+
+      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+      - `thenable` is an object or function that defines a `then` method.
+      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+      - `exception` is a value that is thrown using the throw statement.
+      - `reason` is a value that indicates why a promise was rejected.
+      - `settled` the final resting state of a promise, fulfilled or rejected.
+
+      A promise can be in one of three states: pending, fulfilled, or rejected.
+
+      Promises that are fulfilled have a fulfillment value and are in the fulfilled
+      state.  Promises that are rejected have a rejection reason and are in the
+      rejected state.  A fulfillment value is never a thenable.
+
+      Promises can also be said to *resolve* a value.  If this value is also a
+      promise, then the original promise's settled state will match the value's
+      settled state.  So a promise that *resolves* a promise that rejects will
+      itself reject, and a promise that *resolves* a promise that fulfills will
+      itself fulfill.
+
+
+      Basic Usage:
+      ------------
+
+      ```js
+      var promise = new Promise(function(resolve, reject) {
+        // on success
+        resolve(value);
+
+        // on failure
+        reject(reason);
+      });
+
+      promise.then(function(value) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Advanced Usage:
+      ---------------
+
+      Promises shine when abstracting away asynchronous interactions such as
+      `XMLHttpRequest`s.
+
+      ```js
+      function getJSON(url) {
+        return new Promise(function(resolve, reject){
+          var xhr = new XMLHttpRequest();
+
+          xhr.open('GET', url);
+          xhr.onreadystatechange = handler;
+          xhr.responseType = 'json';
+          xhr.setRequestHeader('Accept', 'application/json');
+          xhr.send();
+
+          function handler() {
+            if (this.readyState === this.DONE) {
+              if (this.status === 200) {
+                resolve(this.response);
+              } else {
+                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+              }
+            }
+          };
+        });
+      }
+
+      getJSON('/posts.json').then(function(json) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Unlike callbacks, promises are great composable primitives.
+
+      ```js
+      Promise.all([
+        getJSON('/posts'),
+        getJSON('/comments')
+      ]).then(function(values){
+        values[0] // => postsJSON
+        values[1] // => commentsJSON
+
+        return values;
+      });
+      ```

+      @param {function} resolver

+      this._result = undefined;
+      this._subscribers = [];
+
+      if (lib$es6$promise$$internal$$noop !== resolver) {
+        if (!lib$es6$promise$utils$$isFunction(resolver)) {
+          lib$es6$promise$promise$$needsResolver();
+        }
+
+        if (!(this instanceof lib$es6$promise$promise$$Promise)) {

+
+    /**
+      The primary way of interacting with a promise is through its `then` method,
+      which registers callbacks to receive either a promise's eventual value or the
+      reason why the promise cannot be fulfilled.
+
+      ```js
+      findUser().then(function(user){
+        // user is available
+      }, function(reason){
+        // user is unavailable, and you are given the reason why
+      });
+      ```
+
+      Chaining
+      --------
+
+      The return value of `then` is itself a promise.  This second, 'downstream'
+      promise is resolved with the return value of the first promise's fulfillment
+      or rejection handler, or rejected if the handler throws an exception.
+
+      ```js
+      findUser().then(function (user) {
+        return user.name;
+      }, function (reason) {
+        return 'default name';
+      }).then(function (userName) {
+        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+        // will be `'default name'`
+      });
+
+      findUser().then(function (user) {
+        throw new Error('Found user, but still unhappy');
+      }, function (reason) {
+        throw new Error('`findUser` rejected and we're unhappy');
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+      });
+      ```
+      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+      ```js
+      findUser().then(function (user) {
+        throw new PedagogicalException('Upstream error');
+      }).then(function (value) {
+        // never reached
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // The `PedgagocialException` is propagated all the way down to here
+      });
+      ```
+
+      Assimilation
+      ------------
+
+      Sometimes the value you want to propagate to a downstream promise can only be
+      retrieved asynchronously. This can be achieved by returning a promise in the
+      fulfillment or rejection handler. The downstream promise will then be pending
+      until the returned promise is settled. This is called *assimilation*.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // The user's comments are now available
+      });
+      ```
+
+      If the assimliated promise rejects, then the downstream promise will also reject.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // If `findCommentsByAuthor` fulfills, we'll have the value here
+      }, function (reason) {
+        // If `findCommentsByAuthor` rejects, we'll have the reason here
+      });
+      ```

+      Synchronous Example

+      var result;
+
+      try {

+      Promise objects represent the eventual result of an asynchronous operation. The
+      primary way of interacting with a promise is through its `then` method, which
+      registers callbacks to receive either a promise’s eventual value or the reason
+      why the promise cannot be fulfilled.
+
+      Terminology
+      -----------
+
+      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+      - `thenable` is an object or function that defines a `then` method.
+      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+      - `exception` is a value that is thrown using the throw statement.
+      - `reason` is a value that indicates why a promise was rejected.
+      - `settled` the final resting state of a promise, fulfilled or rejected.
+
+      A promise can be in one of three states: pending, fulfilled, or rejected.
+
+      Promises that are fulfilled have a fulfillment value and are in the fulfilled
+      state.  Promises that are rejected have a rejection reason and are in the
+      rejected state.  A fulfillment value is never a thenable.
+
+      Promises can also be said to *resolve* a value.  If this value is also a
+      promise, then the original promise's settled state will match the value's
+      settled state.  So a promise that *resolves* a promise that rejects will
+      itself reject, and a promise that *resolves* a promise that fulfills will
+      itself fulfill.
+
+
+      Basic Usage:
+      ------------
+
+      ```js
+      var promise = new Promise(function(resolve, reject) {
+        // on success
+        resolve(value);
+
+        // on failure
+        reject(reason);
+      });
+
+      promise.then(function(value) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Advanced Usage:
+      ---------------
+
+      Promises shine when abstracting away asynchronous interactions such as
+      `XMLHttpRequest`s.
+
+      ```js
+      function getJSON(url) {
+        return new Promise(function(resolve, reject){
+          var xhr = new XMLHttpRequest();
+
+          xhr.open('GET', url);
+          xhr.onreadystatechange = handler;
+          xhr.responseType = 'json';
+          xhr.setRequestHeader('Accept', 'application/json');
+          xhr.send();
+
+          function handler() {
+            if (this.readyState === this.DONE) {
+              if (this.status === 200) {
+                resolve(this.response);
+              } else {
+                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+              }
+            }
+          };
+        });
+      }
+
+      getJSON('/posts.json').then(function(json) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Unlike callbacks, promises are great composable primitives.
+
+      ```js
+      Promise.all([
+        getJSON('/posts'),
+        getJSON('/comments')
+      ]).then(function(values){
+        values[0] // => postsJSON
+        values[1] // => commentsJSON
+
+        return values;
+      });
+      ```

+
+      Chaining
+      --------
+

+      or rejection handler, or rejected if the handler throws an exception.
+

+      });
+
+      findUser().then(function (user) {
+        throw new Error('Found user, but still unhappy');
+      }, function (reason) {
+        throw new Error('`findUser` rejected and we're unhappy');
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+      });
+      ```
+      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+      ```js
+      findUser().then(function (user) {
+        throw new PedagogicalException('Upstream error');
+      }).then(function (value) {
+        // never reached
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // The `PedgagocialException` is propagated all the way down to here
+      });
+      ```
+
+      Assimilation
+      ------------
+
+      Sometimes the value you want to propagate to a downstream promise can only be
+      retrieved asynchronously. This can be achieved by returning a promise in the
+      fulfillment or rejection handler. The downstream promise will then be pending
+      until the returned promise is settled. This is called *assimilation*.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // The user's comments are now available
+      });
+      ```
+
+      If the assimliated promise rejects, then the downstream promise will also reject.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // If `findCommentsByAuthor` fulfills, we'll have the value here
+      }, function (reason) {
+        // If `findCommentsByAuthor` rejects, we'll have the reason here
+      });
+      ```

+/**
+  Promise objects represent the eventual result of an asynchronous operation. The
+  primary way of interacting with a promise is through its `then` method, which
+  registers callbacks to receive either a promise’s eventual value or the reason
+  why the promise cannot be fulfilled.
+
+  Terminology
+  -----------
+
+  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+  - `thenable` is an object or function that defines a `then` method.
+  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+  - `exception` is a value that is thrown using the throw statement.
+  - `reason` is a value that indicates why a promise was rejected.
+  - `settled` the final resting state of a promise, fulfilled or rejected.
+
+  A promise can be in one of three states: pending, fulfilled, or rejected.
+
+  Promises that are fulfilled have a fulfillment value and are in the fulfilled
+  state.  Promises that are rejected have a rejection reason and are in the
+  rejected state.  A fulfillment value is never a thenable.
+
+  Promises can also be said to *resolve* a value.  If this value is also a
+  promise, then the original promise's settled state will match the value's
+  settled state.  So a promise that *resolves* a promise that rejects will
+  itself reject, and a promise that *resolves* a promise that fulfills will
+  itself fulfill.
+
+
+  Basic Usage:
+  ------------
+
+  ```js
+  var promise = new Promise(function(resolve, reject) {
+    // on success
+    resolve(value);
+
+    // on failure
+    reject(reason);
+  });
+
+  promise.then(function(value) {
+    // on fulfillment
+  }, function(reason) {
+    // on rejection
+  });
+  ```
+
+  Advanced Usage:
+  ---------------
+
+  Promises shine when abstracting away asynchronous interactions such as
+  `XMLHttpRequest`s.
+
+  ```js
+  function getJSON(url) {
+    return new Promise(function(resolve, reject){
+      var xhr = new XMLHttpRequest();
+
+      xhr.open('GET', url);
+      xhr.onreadystatechange = handler;
+      xhr.responseType = 'json';
+      xhr.setRequestHeader('Accept', 'application/json');
+      xhr.send();
+
+      function handler() {
+        if (this.readyState === this.DONE) {
+          if (this.status === 200) {
+            resolve(this.response);
+          } else {
+            reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+          }
+        }
+      };
+    });
+  }
+
+  getJSON('/posts.json').then(function(json) {
+    // on fulfillment
+  }, function(reason) {
+    // on rejection
+  });
+  ```
+
+  Unlike callbacks, promises are great composable primitives.
+
+  ```js
+  Promise.all([
+    getJSON('/posts'),
+    getJSON('/comments')
+  ]).then(function(values){
+    values[0] // => postsJSON
+    values[1] // => commentsJSON
+
+    return values;
+  });
+  ```
+
+  @class Promise
+  @param {function} resolver
+  Useful for tooling.
+  @constructor
+*/
+function Promise(resolver) {
+  this._id = counter++;
+  this._state = undefined;
+  this._result = undefined;
+  this._subscribers = [];
+
+  if (noop !== resolver) {
+    if (!isFunction(resolver)) {
+      needsResolver();
+    }
+
+    if (!(this instanceof Promise)) {
+      needsNew();
+    }
+
+    initializePromise(this, resolver);
+  }
+}
+
+Promise.all = all;
+Promise.race = race;
+Promise.resolve = Resolve;
+Promise.reject = Reject;
+
+Promise.prototype = {
+  constructor: Promise,
+
+/**
+  The primary way of interacting with a promise is through its `then` method,
+  which registers callbacks to receive either a promise's eventual value or the
+  reason why the promise cannot be fulfilled.
+
+  ```js
+  findUser().then(function(user){
+    // user is available
+  }, function(reason){
+    // user is unavailable, and you are given the reason why
+  });
+  ```
+
+  Chaining
+  --------
+
+  The return value of `then` is itself a promise.  This second, 'downstream'
+  promise is resolved with the return value of the first promise's fulfillment
+  or rejection handler, or rejected if the handler throws an exception.
+
+  ```js
+  findUser().then(function (user) {
+    return user.name;
+  }, function (reason) {
+    return 'default name';
+  }).then(function (userName) {
+    // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+    // will be `'default name'`
+  });
+
+  findUser().then(function (user) {
+    throw new Error('Found user, but still unhappy');
+  }, function (reason) {
+    throw new Error('`findUser` rejected and we're unhappy');
+  }).then(function (value) {
+    // never reached
+  }, function (reason) {
+    // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+    // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+  });
+  ```
+  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+  ```js
+  findUser().then(function (user) {
+    throw new PedagogicalException('Upstream error');
+  }).then(function (value) {
+    // never reached
+  }).then(function (value) {
+    // never reached
+  }, function (reason) {
+    // The `PedgagocialException` is propagated all the way down to here
+  });
+  ```
+
+  Assimilation
+  ------------
+
+  Sometimes the value you want to propagate to a downstream promise can only be
+  retrieved asynchronously. This can be achieved by returning a promise in the
+  fulfillment or rejection handler. The downstream promise will then be pending
+  until the returned promise is settled. This is called *assimilation*.
+
+  ```js
+  findUser().then(function (user) {
+    return findCommentsByAuthor(user);
+  }).then(function (comments) {
+    // The user's comments are now available
+  });
+  ```
+
+  If the assimliated promise rejects, then the downstream promise will also reject.
+
+  ```js
+  findUser().then(function (user) {
+    return findCommentsByAuthor(user);
+  }).then(function (comments) {
+    // If `findCommentsByAuthor` fulfills, we'll have the value here
+  }, function (reason) {
+    // If `findCommentsByAuthor` rejects, we'll have the reason here
+  });
+  ```
+
+  Simple Example
+  --------------
+
+  Synchronous Example
+
+  ```javascript
+  var result;
+
+  try {
+    result = findResult();
+    // success
+  } catch(reason) {
+    // failure
+  }
+  ```
+
+  Errback Example
+
+  ```js
+  findResult(function(result, err){
+    if (err) {
+      // failure
+    } else {
+      // success

+

+    setTimeout(function(){
+      resolve('promise 2');
+    }, 100);
+  });
+
+  Promise.race([promise1, promise2]).then(function(result){
+    // result === 'promise 2' because it was resolved before promise1
+    // was resolved.
+  });
+  ```
+
+  `Promise.race` is deterministic in that only the state of the first
+  settled promise matters. For example, even if other promises given to the
+  `promises` array argument are resolved, but the first settled promise has
+  become rejected before the other promises became fulfilled, the returned
+  promise will become rejected:
+
+  ```javascript
+  var promise1 = new Promise(function(resolve, reject){
+    setTimeout(function(){
+      resolve('promise 1');
+    }, 200);
+  });
+
+  var promise2 = new Promise(function(resolve, reject){
+    setTimeout(function(){
+      reject(new Error('promise 2'));
+    }, 100);
+  });
+
+  Promise.race([promise1, promise2]).then(function(result){
+    // Code here never runs
+  }, function(reason){
+    // reason.message === 'promise 2' because promise 2 became rejected before
+    // promise 1 became fulfilled
+  });
+  ```
+
+  An example real-world use case is implementing timeouts:
+
+  ```javascript
+  Promise.race([ajax('foo.json'), timeout(5000)])
+  ```
+
+  @method race
+  @static
+  @param {Array} promises array of promises to observe
+  Useful for tooling.
+  @return {Promise} a promise which settles in the same way as the first passed
+  promise to settle.

-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>

-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.cyan('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. Use the right colors for values. If you pass in multiple arguments it will join them by a space.
-
-```
-values (files, module names, etc.) = magenta
-numbers (times, counts, etc) = cyan
-```
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/');
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files){
-  
-  });
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});
-```

+
+## Usage
+
+```javascript
+var gutil = require('gulp-util');
+
+gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
+gutil.beep();
+
+gutil.replaceExtension('file.coffee', '.js'); // file.js
+
+var opt = {
+  name: 'todd',
+  file: someGulpFile
+};
+gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
+```
+
+### log(msg...)
+
+Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
+
+The default gulp coloring using gutil.colors.<color>:
+```
+values (files, module names, etc.) = cyan
+numbers (times, counts, etc) = magenta
+```
+
+### colors
+
+Is an instance of [chalk](https://github.com/sindresorhus/chalk).
+
+### replaceExtension(path, newExtension)
+
+Replaces a file extension in a path. Returns the new path.
+
+### isStream(obj)
+
+Returns true or false if an object is a stream.
+
+### isBuffer(obj)
+
+Returns true or false if an object is a Buffer.
+
+### template(string[, data])
+
+This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
+
+## new File(obj)
+
+This is just [vinyl](https://github.com/wearefractal/vinyl)
+
+```javascript
+var file = new gutil.File({
+  base: path.join(__dirname, './fixtures/'),
+  cwd: __dirname,
+  path: path.join(__dirname, './fixtures/test.coffee')
+});
+```
+
+## noop()
+
+Returns a stream that does nothing but pass data straight through.
+
+```javascript
+// gulp should be called like this :
+// $ gulp --type production
+gulp.task('scripts', function() {
+  gulp.src('src/**/*.js')
+    .pipe(concat('script.js'))
+    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
+    .pipe(gulp.dest('dist/'));
+});
+```
+
+## buffer(cb)
+
+This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
+
+Returns a stream that can be piped to.
+
+The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
+
+Callback is optional and receives two arguments: error and data
+
+```javascript
+gulp.src('stuff/*.js')
+  .pipe(gutil.buffer(function(err, files) {
+  
+  }));
+```
+
+## new PluginError(pluginName, message[, options])
+
+- pluginName should be the module name of your plugin
+- message can be a string or an existing error
+- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
+- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
+- Note that if you pass in a custom stack string you need to include the message along with that.
+- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
+
+These are all acceptable forms of instantiation:
+
+```javascript
+var err = new gutil.PluginError('test', {
+  message: 'something broke'
+});
+
+var err = new gutil.PluginError({
+  plugin: 'test',
+  message: 'something broke'
+});
+
+var err = new gutil.PluginError('test', 'something broke');
+
+var err = new gutil.PluginError('test', 'something broke', {showStack: true});
+
+var existingError = new Error('OMG');
+var err = new gutil.PluginError('test', existingError, {showStack: true});
+```

+
+> Create an array without duplicates
+
+It's already pretty fast, but will be much faster when [Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set) becomes available in V8 (especially with large arrays).
+
+
+## Install
+
+```sh
+$ npm install --save array-uniq
+```
+
+
+## Usage
+
+```js
+var arrayUniq = require('array-uniq');
+
+arrayUniq([1, 1, 2, 3, 3]);
+//=> [1, 2, 3]
+
+arrayUniq(['foo', 'foo', 'bar', 'foo']);
+//=> ['foo', 'bar']
+```

-> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
-
-You probably want the higher-level [chalk](https://github.com/sindresorhus/chalk) module for styling your strings.
-
-![screenshot](screenshot.png)

-
-## Install
-
-```sh
-$ npm install --save ansi-styles
-```

-var ansi = require('ansi-styles');
-
-console.log(ansi.green.open + 'Hello world!' + ansi.green.close);
-```
-
-
-## API
-
-Each style has an `open` and `close` property.

+
+## Install
+

+
+
+## Usage
+
+```js
+var ansi = require('ansi-styles');
+

+```
+
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## Advanced usage
+
+By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `ansi.modifiers`
+- `ansi.colors`
+- `ansi.bgColors`
+
+
+###### Example
+
+```js
+console.log(ansi.colors.green.open);
+```

-> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
-
-
-## Install
-
-```sh
-$ npm install --save ansi-regex
-```
-
-
-## Usage
-
-```js
-var ansiRegex = require('ansi-regex');
-
-ansiRegex().test('\u001b[4mcake\u001b[0m');
-//=> true
-
-ansiRegex().test('cake');
-//=> false
-
-'\u001b[4mcake\u001b[0m'.match(ansiRegex());
-//=> ['\u001b[4m', '\u001b[0m']
-```
-
-*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

-## Install

-
-
-## Usage
-
-```js
-var ansiRegex = require('ansi-regex');
-
-ansiRegex().test('\u001b[4mcake\u001b[0m');
-//=> true
-
-ansiRegex().test('cake');

-'\u001b[4mcake\u001b[0m'.match(ansiRegex());
-//=> ['\u001b[4m', '\u001b[0m']
-```
-
-*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

-> Terminal string styling done right
-
-[![Build Status](https://travis-ci.org/sindresorhus/chalk.svg?branch=master)](https://travis-ci.org/sindresorhus/chalk)
-![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)
-
-[colors.js](https://github.com/Marak/colors.js) is currently the most popular string styling module, but it has serious deficiencies like extending String.prototype which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
-
-**Chalk is a clean and focused alternative.**
-
-![screenshot](https://github.com/sindresorhus/ansi-styles/raw/master/screenshot.png)
-
-
-## Why
-
-- Highly performant
-- Doesn't extend String.prototype
-- Expressive API
-- Ability to nest styles
-- Clean and focused
-- Auto-detects color support
-- Actively maintained
-- [Used by 1000+ modules](https://npmjs.org/browse/depended/chalk)
-
-
-## Install
-
-```sh
-$ npm install --save chalk
-```
-
-
-## Usage
-
-Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
-
-```js
-var chalk = require('chalk');
-
-// style a string
-console.log(  chalk.blue('Hello world!')  );
-
-// combine styled and normal strings
-console.log(  chalk.blue('Hello'), 'World' + chalk.red('!')  );
-
-// compose multiple styles using the chainable API
-console.log(  chalk.blue.bgRed.bold('Hello world!')  );
-
-// pass in multiple arguments
-console.log(  chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz')  );
-
-// nest styles
-console.log(  chalk.red('Hello', chalk.underline.bgBlue('world') + '!')  );
-
-// nest styles of the same type even (color, underline, background)
-console.log(  chalk.green('I am a green line ' + chalk.blue('with a blue substring') + ' that becomes green again!')  );
-```
-
-Easily define your own themes.
-
-```js
-var chalk = require('chalk');
-var error = chalk.bold.red;
-console.log(error('Error!'));
-```
-
-Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
-
-```js
-var name = 'Sindre';
-console.log(chalk.green('Hello %s'), name);
-//=> Hello Sindre
-```
-
-
-## API
-
-### chalk.`<style>[.<style>...](string, [string...])`
-
-Example: `chalk.red.bold.underline('Hello', 'world');`
-
-Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter.
-
-Multiple arguments will be separated by space.
-
-### chalk.enabled
-
-Color support is automatically detected, but you can override it.
-
-### chalk.supportsColor
-
-Detect whether the terminal [supports color](https://github.com/sindresorhus/supports-color).
-
-Can be overridden by the user with the flags `--color` and `--no-color`.
-
-Used internally and handled for you, but exposed for convenience.
-
-### chalk.styles
-
-Exposes the styles as [ANSI escape codes](https://github.com/sindresorhus/ansi-styles).
-
-Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with yours.
-
-```js
-var chalk = require('chalk');
-
-console.log(chalk.styles.red);
-//=> {open: '\u001b[31m', close: '\u001b[39m'}
-
-console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
-```
-
-### chalk.hasColor(string)
-
-Check whether a string [has color](https://github.com/sindresorhus/has-ansi).
-
-### chalk.stripColor(string)
-
-[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.
-
-Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
-
-Example:
-
-```js
-var chalk = require('chalk');
-var styledString = getText();
-
-if (!chalk.supportsColor) {
-	styledString = chalk.stripColor(styledString);
-}
-```

+> Terminal string styling done right
+
+[![Build Status](https://travis-ci.org/sindresorhus/chalk.svg?branch=master)](https://travis-ci.org/sindresorhus/chalk) [![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg?style=flat)](https://www.youtube.com/watch?v=Sm368W0OsHo)
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
+
+**Chalk is a clean and focused alternative.**
+
+![screenshot](https://github.com/sindresorhus/ansi-styles/raw/master/screenshot.png)
+
+
+## Why
+
+- Highly performant
+- Doesn't extend `String.prototype`
+- Expressive API
+- Ability to nest styles
+- Clean and focused
+- Auto-detects color support
+- Actively maintained
+- [Used by ~3000 modules](https://www.npmjs.com/browse/depended/chalk)
+
+
+## Install
+
+```
+$ npm install --save chalk
+```
+
+
+## Usage
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+var chalk = require('chalk');
+
+// style a string
+chalk.blue('Hello world!');
+
+// combine styled and normal strings
+chalk.blue('Hello') + 'World' + chalk.red('!');
+
+// compose multiple styles using the chainable API
+chalk.blue.bgRed.bold('Hello world!');
+
+// pass in multiple arguments
+chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz');
+
+// nest styles
+chalk.red('Hello', chalk.underline.bgBlue('world') + '!');
+
+// nest styles of the same type even (color, underline, background)
+chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+);
+```
+
+Easily define your own themes.
+
+```js
+var chalk = require('chalk');
+var error = chalk.bold.red;
+console.log(error('Error!'));
+```
+
+Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
+
+```js
+var name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> Hello Sindre
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `Chalk.red.yellow.green` is equivalent to `Chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, but you can override it by setting the `enabled` property. You should however only do this in your own code as it applies globally to all chalk consumers.
+
+If you need to change this in a reusable module create a new instance:
+
+```js
+var ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/sindresorhus/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.
+
+### chalk.styles
+
+Exposes the styles as [ANSI escape codes](https://github.com/sindresorhus/ansi-styles).
+
+Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with your own.
+
+```js
+var chalk = require('chalk');
+
+console.log(chalk.styles.red);
+//=> {open: '\u001b[31m', close: '\u001b[39m'}
+
+console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
+```
+
+### chalk.hasColor(string)
+
+Check whether a string [has color](https://github.com/sindresorhus/has-ansi).
+
+### chalk.stripColor(string)
+
+[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.
+
+Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
+
+Example:
+
+```js
+var chalk = require('chalk');
+var styledString = getText();
+
+if (!chalk.supportsColor) {
+	styledString = chalk.stripColor(styledString);
+}
+```
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue` *(on Windows the bright version is used as normal blue is illegible)*
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## 256-colors
+
+Chalk does not support support anything other than the base eight colors, which guarantees it will work on all terminals and systems. Some terminals, specifically `xterm` compliant ones, will support the full range of 8-bit colors. For this the lower level [ansi-256-colors](https://github.com/jbnicolai/ansi-256-colors) package can be used.
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://bliker.github.io/cmder/) instead of `cmd.exe`.

-# dateformat
-
-A node.js package for Steven Levithan's excellent [dateFormat()][dateformat] function.
-
-## Modifications
-
-* Removed the `Date.prototype.format` method. Sorry folks, but extending native prototypes is for suckers.
-* Added a `module.exports = dateFormat;` statement at the bottom
-* Added the placeholder `N` to get the ISO 8601 numeric representation of the day of the week
-
-## Installation
-
-```bash
-$ npm install dateformat
-```
-
-## Usage
-
-As taken from Steven's post, modified to match the Modifications listed above:
-```js
-    var dateFormat = require('dateformat');
-    var now = new Date();
-
-    // Basic usage
-    dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
-    // Saturday, June 9th, 2007, 5:46:21 PM
-
-    // You can use one of several named masks
-    dateFormat(now, "isoDateTime");
-    // 2007-06-09T17:46:21
-
-    // ...Or add your own
-    dateFormat.masks.hammerTime = 'HH:MM! "Can\'t touch this!"';
-    dateFormat(now, "hammerTime");
-    // 17:46! Can't touch this!
-
-    // When using the standalone dateFormat function,
-    // you can also provide the date as a string
-    dateFormat("Jun 9 2007", "fullDate");
-    // Saturday, June 9, 2007
-
-    // Note that if you don't include the mask argument,
-    // dateFormat.masks.default is used
-    dateFormat(now);
-    // Sat Jun 09 2007 17:46:21
-
-    // And if you don't include the date argument,
-    // the current date and time is used
-    dateFormat();
-    // Sat Jun 09 2007 17:46:22
-
-    // You can also skip the date argument (as long as your mask doesn't
-    // contain any numbers), in which case the current date/time is used
-    dateFormat("longTime");
-    // 5:46:22 PM EST
-
-    // And finally, you can convert local time to UTC time. Simply pass in
-    // true as an additional argument (no argument skipping allowed in this case):
-    dateFormat(now, "longTime", true);
-    // 10:46:21 PM UTC
-
-    // ...Or add the prefix "UTC:" or "GMT:" to your mask.
-    dateFormat(now, "UTC:h:MM:ss TT Z");
-    // 10:46:21 PM UTC
-
-    // You can also get the ISO 8601 week of the year:
-    dateFormat(now, "W");
-    // 42
-
-    // and also get the ISO 8601 numeric representation of the day of the week:

+# lodash.isarray v3.0.3
+
+The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash’s](https://lodash.com/) `_.isArray` exported as a [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) module.
+
+## Installation
+
+Using npm:
+
+```bash
+$ {sudo -H} npm i -g npm
+$ npm i --save lodash.isarray
+```
+
+In Node.js/io.js:
+
+```js
+var isArray = require('lodash.isarray');
+```

-# Lo-Dash v2.4.1
-A utility library delivering consistency, [customization](http://lodash.com/custom-builds), [performance](http://lodash.com/benchmarks), & [extras](http://lodash.com/#features).
-
-## Download
-
-Check out our [wiki]([https://github.com/lodash/lodash/wiki/build-differences]) for details over the differences between builds.
-
-* Modern builds perfect for newer browsers/environments:<br>
-[Development](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.js) &
-[Production](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.min.js)
-
-* Compatibility builds for older environment support too:<br>
-[Development](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.compat.js) &
-[Production](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.compat.min.js)
-
-* Underscore builds to use as a drop-in replacement:<br>
-[Development](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.underscore.js) &
-[Production](https://raw.github.com/lodash/lodash/2.4.1/dist/lodash.underscore.min.js)
-
-CDN copies are available on [cdnjs](http://cdnjs.com/libraries/lodash.js/) & [jsDelivr](http://www.jsdelivr.com/#!lodash). For smaller file sizes, create [custom builds](http://lodash.com/custom-builds) with only the features needed.
-
-Love modules? We’ve got you covered with [lodash-amd](https://npmjs.org/package/lodash-amd), [lodash-es6](https://github.com/lodash/lodash-es6), [lodash-node](https://npmjs.org/package/lodash-node), & [npm packages](https://npmjs.org/browse/keyword/lodash-modularized) per method.
-
-## Dive in
-
-There’s plenty of **[documentation](http://lodash.com/docs)**, [unit tests](http://lodash.com/tests), & [benchmarks](http://lodash.com/benchmarks).<br>
-Check out <a href="http://devdocs.io/lodash/">DevDocs</a> as a fast, organized, & searchable interface for our documentation.
-
-The full changelog for this release is available on our [wiki](https://github.com/lodash/lodash/wiki/Changelog).<br>
-A list of upcoming features is available on our [roadmap](https://github.com/lodash/lodash/wiki/Roadmap).
-
-## Features *not* in Underscore
-
- * AMD loader support ([curl](https://github.com/cujojs/curl), [dojo](http://dojotoolkit.org/), [requirejs](http://requirejs.org/), etc.)
- * [_(…)](http://lodash.com/docs#_) supports intuitive chaining
- * [_.at](http://lodash.com/docs#at) for cherry-picking collection values
- * [_.bindKey](http://lodash.com/docs#bindKey) for binding [*“lazy”*](http://michaux.ca/articles/lazy-function-definition-pattern) defined methods
- * [_.clone](http://lodash.com/docs#clone) supports shallow cloning of `Date` & `RegExp` objects
- * [_.cloneDeep](http://lodash.com/docs#cloneDeep) for deep cloning arrays & objects
- * [_.constant](http://lodash.com/docs#constant) & [_.property](http://lodash.com/docs#property) function generators for composing functions

-   * Creates a `lodash` object which wraps the given value to enable intuitive

-   *
-   * In addition to Lo-Dash methods, wrappers also have the following `Array` methods:
-   * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
-   * and `unshift`
-   *
-   * Chaining is supported in custom builds as long as the `value` method is
-   * implicitly or explicitly included in the build.
-   *
-   * The chainable wrapper functions are:
-   * `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`,
-   * `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`,
-   * `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`,
-   * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
-   * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
-   * `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`,
-   * `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`,
-   * `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`,
-   * `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`,
-   * `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`,
-   * and `zip`
-   *
-   * The non-chainable wrapper functions are:
-   * `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`,
-   * `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`,
-   * `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
-   * `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`,

-   * `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`,
-   * `template`, `unescape`, `uniqueId`, and `value`
-   *
-   * The wrapper functions `first` and `last` return wrapped values when `n` is

-     * Creates a `lodash` object which wraps the given value to enable intuitive
-     * method chaining.
-     *
-     * In addition to Lo-Dash methods, wrappers also have the following `Array` methods:
-     * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
-     * and `unshift`
-     *
-     * Chaining is supported in custom builds as long as the `value` method is
-     * implicitly or explicitly included in the build.
-     *
-     * The chainable wrapper functions are:
-     * `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`,
-     * `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`,
-     * `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`,
-     * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
-     * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
-     * `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`,
-     * `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`,
-     * `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`,
-     * `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`,
-     * `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`,
-     * and `zip`
-     *
-     * The non-chainable wrapper functions are:
-     * `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`,
-     * `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`,
-     * `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
-     * `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`,

-first non-option
-* `opts['--']` - when true, populate `argv._` with everything before the `--`

-# multipipe
-
-A better `Stream#pipe` that creates duplex streams and lets you handle errors in one place.
-
-[![build status](https://secure.travis-ci.org/segmentio/multipipe.png)](http://travis-ci.org/segmentio/multipipe)
-
-## Example
-
-```js
-var pipe = require('multipipe');
-
-// pipe streams
-var stream = pipe(streamA, streamB, streamC);
-
-// centralized error handling
-stream.on('error', fn);
-
-// creates a new stream
-source.pipe(stream).pipe(dest);
-
-// optional callback on finish or error
-pipe(streamA, streamB, streamC, function(err){
-  // ...
-});
-```
-
-## Duplex streams
-
-  Write to the pipe and you'll really write to the first stream, read from the pipe and you'll read from the last stream.
-
-```js
-var stream = pipe(a, b, c);
-
-source
-  .pipe(stream)
-  .pipe(destination);
-```
-
-  In this example the flow of data is:
-
-  * source ->
-  * a ->
-  * b ->
-  * c ->
-  * destination
-
-## Error handling
-
-  Each `pipe` forwards the errors the streams it wraps emit, so you have one central place to handle errors:
-
-```js
-var stream = pipe(a, b, c);
-
-stream.on('error', function(err){
-  // called three times
-});
-
-a.emit('error', new Error);
-b.emit('error', new Error);
-c.emit('error', new Error);
-```
-
-## API
-
-### pipe(stream, ...)
-
-Pass a variable number of streams and each will be piped to the next one.
-
-A stream will be returned that wraps passed in streams in a way that errors will be forwarded and you can write to and/or read from it.
-
-Pass a function as last argument to be called on `error` or `finish` of the last stream.
-

-
-```bash
-$ npm install multipipe
-```

-duplexer2 [![build status](https://travis-ci.org/deoxxa/duplexer2.png)](https://travis-ci.org/deoxxa/fork)
-=========
-
-Like duplexer (http://npm.im/duplexer) but using streams2.
-
-Overview
---------
-
-duplexer2 is a reimplementation of [duplexer](http://npm.im/duplexer) using the
-readable-stream API which is standard in node as of v0.10. Everything largely
-works the same.
-
-Installation
-------------
-
-Available via [npm](http://npmjs.org/):
-
-> $ npm install duplexer2
-
-Or via git:
-
-> $ git clone git://github.com/deoxxa/duplexer2.git node_modules/duplexer2
-
-API
----
-
-**duplexer2**
-
-Creates a new `DuplexWrapper` object, which is the actual class that implements
-most of the fun stuff. All that fun stuff is hidden. DON'T LOOK.
-
-```javascript
-duplexer2([options], writable, readable)
-```
-
-```javascript
-var duplex = duplexer2(new stream.Writable(), new stream.Readable());
-```
-
-Arguments
-
-* __options__ - an object specifying the regular `stream.Duplex` options, as
-  well as the properties described below.
-* __writable__ - a writable stream
-* __readable__ - a readable stream
-
-Options
-
-* __bubbleErrors__ - a boolean value that specifies whether to bubble errors
-  from the underlying readable/writable streams. Default is `true`.
-
-Example
--------
-
-Also see [example.js](https://github.com/deoxxa/duplexer2/blob/master/example.js).
-
-Code:
-
-```javascript
-var stream = require("stream");
-
-var duplexer2 = require("duplexer2");
-
-var writable = new stream.Writable({objectMode: true}),
-    readable = new stream.Readable({objectMode: true});
-
-writable._write = function _write(input, encoding, done) {
-  if (readable.push(input)) {
-    return done();
-  } else {
-    readable.once("drain", done);
-  }
-};
-
-readable._read = function _read(n) {
-  // no-op
-};
-
-// simulate the readable thing closing after a bit
-writable.once("finish", function() {
-  setTimeout(function() {
-    readable.push(null);
-  }, 500);
-});
-
-var duplex = duplexer2(writable, readable);
-
-duplex.on("data", function(e) {
-  console.log("got data", JSON.stringify(e));
-});
-
-duplex.on("finish", function() {
-  console.log("got finish event");
-});
-
-duplex.on("end", function() {
-  console.log("got end event");
-});
-
-duplex.write("oh, hi there", function() {
-  console.log("finished writing");
-});
-
-duplex.end(function() {
-  console.log("finished ending");
-});
-```
-
-Output:
-
-```
-got data "oh, hi there"
-finished writing
-got finish event
-finished ending

-This package is a mirror of the Streams2 and Streams3 implementations in Node-core.

-If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
-
-**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
-
-**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
+
+> ES6 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) ponyfill
+
+> Ponyfill: A polyfill that doesn't overwrite the native method
+
+
+## Install
+
+```sh
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+var objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, source, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

-```
-
-### constructor(options)
-
-#### options.cwd
-
-Type: `String`  
-Default: `process.cwd()`
-
-#### options.base
-
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`  
-Default: `options.cwd`
-
-#### options.path
-
-Full path to the file.
-
-Type: `String`  
-Default: `null`
-
-#### options.stat
-
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`  
-Default: `null`
-
-#### options.contents
-
-File contents.
-
-Type: `Buffer, Stream, or null`  
-Default: `null`
-
-### isBuffer()
-
-Returns true if file.contents is a Buffer.
-
-### isStream()
-
-Returns true if file.contents is a Stream.
-
-### isNull()
-
-Returns true if file.contents is null.
-
-### clone()
-
-Returns a new File object with all attributes cloned. Custom attributes are deep-cloned.
-
-### pipe(stream[, opt])
-
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### relative
-
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee

+# clone
+
+[![build status](https://secure.travis-ci.org/pvorb/node-clone.png)](http://travis-ci.org/pvorb/node-clone)
+
+offers foolproof _deep cloning_ of variables in JavaScript.
+
+
+## Installation
+
+    npm install clone
+
+or
+
+    ender build clone
+
+
+## Example
+
+~~~ javascript
+var clone = require('clone');
+
+var a, b;
+
+a = { foo: { bar: 'baz' } };  // initial value of a
+
+b = clone(a);                 // clone a -> b
+a.foo.bar = 'foo';            // change a
+
+console.log(a);               // show a
+console.log(b);               // show b
+~~~
+
+This will print:
+
+~~~ javascript
+{ foo: { bar: 'foo' } }
+{ foo: { bar: 'baz' } }
+~~~
+
+**clone** masters cloning simple objects (even with custom prototype), arrays,
+Date objects, and RegExp objects. Everything is cloned recursively, so that you
+can clone dates in arrays in objects, for example.
+
+
+## API
+
+`clone(val, circular, depth)`
+
+  * `val` -- the value that you want to clone, any type allowed
+  * `circular` -- boolean
+
+    Call `clone` with `circular` set to `false` if you are certain that `obj`
+    contains no circular references. This will give better performance if needed.
+    There is no error if `undefined` or `null` is passed as `obj`.
+  * `depth` -- depth to which the object is to be cloned (optional,
+    defaults to infinity)
+
+`clone.clonePrototype(obj)`
+
+  * `obj` -- the object that you want to clone
+
+Does a prototype clone as
+[described by Oran Looney](http://oranlooney.com/functional-javascript/).
+
+
+## Circular References
+
+~~~ javascript
+var a, b;
+
+a = { hello: 'world' };
+
+a.myself = a;
+b = clone(a);
+
+console.log(b);
+~~~
+
+This will print:
+
+~~~ javascript
+{ hello: "world", myself: [Circular] }
+~~~
+
+So, `b.myself` points to `b`, not `a`. Neat!
+
+
+## Test
+
+    npm test
+
+
+## Caveat
+
+Some special objects like a socket or `process.stdout`/`stderr` are known to not
+be cloneable. If you find other objects that cannot be cloned, please [open an
+issue](https://github.com/pvorb/node-clone/issues/new).
+
+
+## Bugs and Issues
+
+If you encounter any bugs or issues, feel free to [open an issue at
+github](https://github.com/pvorb/node-clone/issues) or send me an email to
+<paul@vorba.ch>. I also always like to hear from you, if you’re using my code.

-**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
-
-Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
-
-Note: A **Streams3** version of through2 is available in npm with the tag `"1.0"` rather than `"latest"` so an `npm install through2` will get you the current Streams2 version (version number is 0.x.x). To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
-
-```js
-fs.createReadStream('ex.txt')
-  .pipe(through2(function (chunk, enc, callback) {
-    for (var i = 0; i < chunk.length; i++)
-      if (chunk[i] == 97)
-        chunk[i] = 122 // swap 'a' for 'z'
-
-    this.push(chunk)
-
-    callback()
-   }))
-  .pipe(fs.createWriteStream('out.txt'))
-```
-
-Or object streams:
-
-```js
-var all = []
-
-fs.createReadStream('data.csv')
-  .pipe(csv2())
-  .pipe(through2.obj(function (chunk, enc, callback) {
-    var data = {
-        name    : chunk[0]
-      , address : chunk[3]
-      , phone   : chunk[10]
-    }
-    this.push(data)
-
-    callback()
-  }))
-  .on('data', function (data) {
-    all.push(data)
-  })
-  .on('end', function () {
-    doSomethingSpecial(all)
-  })
-```
-
-Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
-
-## API
-
-<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
-
-Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
-
-### options
-
-The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
-
-The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2({ objectMode: true, allowHalfOpen: false },
-    function (chunk, enc, cb) {
-      cb(null, 'wut?') // note we can use the second argument on the callback
-                       // to provide data as an alternative to this.push('wut?')
-    }
-  )
-  .pipe(fs.createWriteStream('/tmp/wut.txt'))
-```
-
-### transformFunction
-
-The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
-
-To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
-
-Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
-
-If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
-
-### flushFunction
-
-The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2(
-    function (chunk, enc, cb) { cb(null, chunk) }, // transform is a noop
-    function (cb) { // flush function
-      this.push('tacking on an extra buffer to the end');
-      cb();
-    }
-  ))
-  .pipe(fs.createWriteStream('/tmp/wut.txt'));
-```
-
-<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
-
-Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
-
-```js
-var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
-  if (record.temp != null && record.unit = "F") {
-    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
-    record.unit = "C"
-  }
-  this.push(record)
-  callback()
-})
-
-// Create instances of FToC like so:
-var converter = new FToC()
-// Or:
-var converter = FToC()
-// Or specify/override options when you instantiate, if you prefer:
-var converter = FToC({objectMode: true})
-```

-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a",
-    b: 'c'
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }

-# [gulp](http://gulpjs.com)-changed [![Build Status](https://travis-ci.org/sindresorhus/gulp-changed.svg?branch=master)](https://travis-ci.org/sindresorhus/gulp-changed)
-
-> Only pass through changed files
-
-No more wasting precious time on processing unchanged files.
-
-By default it's only able to detect whether files in the stream changed. If you require something more advanced like knowing if imports/dependencies changed, create a custom comparator, or use [another plugin](https://github.com/gulpjs/gulp#incremental-builds).
-
-
-## Install
-
-```sh
-$ npm install --save-dev gulp-changed
-```
-
-
-## Usage
-
-```js
-var gulp = require('gulp');
-var changed = require('gulp-changed');
-var ngmin = require('gulp-ngmin'); // just as an example
-
-var SRC = 'src/*.js';
-var DEST = 'dist';
-
-gulp.task('default', function () {
-	return gulp.src(SRC)
-		.pipe(changed(DEST))
-		// ngmin will only get the files that
-		// changed since the last time it was run
-		.pipe(ngmin())
-		.pipe(gulp.dest(DEST));
-});
-```
-
-## API
-
-### changed(destination, options)
-
-#### destination
-
-Type: `string`
-
-The destination directory. Same as you put into `gulp.dest()`.
-
-This is needed to be able to compare the current files with the destination files.
-
-#### options
-
-##### cwd
-
-Type: `string`  
-Default: `process.cwd()`
-
-The working directory the folder is relative to.
-
-##### extension
-
-Type: `string`
-
-Extension of the destination files.
-
-Useful if it differs from the original, like in the example below:
-
-```js
-gulp.task('jade', function () {
-	gulp.src('src/**/*.jade')
-		.pipe(changed('app', {extension: '.html'}))
-		.pipe(jade())
-		.pipe(gulp.dest('app'))
-});
-```
-
-##### hasChanged
-
-Type: `function`  
-Default: `changed.compareLastModifiedTime`
-
-Function that determines whether the source file is different from the destination file.
-
-###### Built-in comparators
-
-- `changed.compareLastModifiedTime`
-- `changed.compareSha1Digest`
-
-###### Example
-
-```js
-gulp.task('jade', function () {
-	gulp.src('src/**/*.jade')
-		.pipe(changed('app', {hasChanged: changed.compareSha1Digest}))
-		.pipe(jade())
-		.pipe(gulp.dest('app'));
-});
-```
-
-You can also supply a custom comparator function which will receive the following arguments:
-
-- `stream` *([transform object stream](https://github.com/rvagg/through2#transformfunction))* - should be used to queue `sourceFile` if it passes some comparison
-- `callback` *(function)* - should be called when done
-- `sourceFile` *([vinyl file object](https://github.com/wearefractal/vinyl#file))*
-- `destPath` *(string)* - destination for `sourceFile` as an absolute path
-

+gulp.task('jade', function () {
+	gulp.src('src/**/*.jade')
+		.pipe(changed('app', {extension: '.html'}))
+		.pipe(jade())
+		.pipe(gulp.dest('app'))
+});
+```
+
+##### hasChanged
+
+Type: `function`  
+Default: `changed.compareLastModifiedTime`
+
+Function that determines whether the source file is different from the destination file.
+
+###### Built-in comparators
+
+- `changed.compareLastModifiedTime`
+- `changed.compareSha1Digest`
+
+###### Example
+
+```js
+gulp.task('jade', function () {
+	gulp.src('src/**/*.jade')
+		.pipe(changed('app', {hasChanged: changed.compareSha1Digest}))
+		.pipe(jade())
+		.pipe(gulp.dest('app'));
+});
+```
+
+You can also supply a custom comparator function which will receive the following arguments:
+
+- `stream` *([transform object stream](https://github.com/rvagg/through2#transformfunction))* - should be used to queue `sourceFile` if it passes some comparison
+- `callback` *(function)* - should be called when done
+- `sourceFile` *([vinyl file object](https://github.com/wearefractal/vinyl#file))*
+- `destPath` *(string)* - destination for `sourceFile` as an absolute path

-> A handy command line interface for gulp
-
-## Installation
-
-```shell
-npm install --save-dev gulp-shell
-```
-
-## Usage
-
-```js
-var gulp  = require('gulp')
-var shell = require('gulp-shell')
-
-gulp.task('example', function () {
-  return gulp.src('*.js', {read: false})
-    .pipe(shell([
-      'echo <%= f(file.path) %>',
-      'ls -l <%= file.path %>'
-    ], {
-      templateData: {
-        f: function (s) {
-          return s.replace(/$/, '.bak')
-        }
-      }
-    }))
-})
-```
-
-If you just want to execute a series of commands only once, starting the stream with `gulp.src('')` should do the trick.
-
-Or you can use this shorthand:
-
-```js
-gulp.task('shorthand', shell.task([
-  'echo hello',
-  'echo world'
-]))
-```
-
-You can find more examples in the [gulpfile][] of this project.
-
-[gulpfile]: https://github.com/sun-zheng-an/gulp-shell/blob/master/gulpfile.js
-
-## API
-
-### shell(commands, options) or shell.task(commands, options)
-
-#### commands
-
-type: `Array` or `String`
-
-A command can be a [template][] which can be interpolated by some [file][] info (e.g. `file.path`).
-
-[template]: http://lodash.com/docs#template
-[file]:     https://github.com/wearefractal/vinyl
-
-#### options.ignoreErrors
-
-type: `Boolean`
-
-default: `false`
-
-By default, it will emit an `error` event when the command finishes unsuccessfully.
-
-#### options.quiet
-
-type: `Boolean`
-
-default: `false`
-
-By default, it will print the command output.
-
-#### options.cwd
-
-type: `String`
-
-default: [`process.cwd()`](http://nodejs.org/api/process.html#process_process_cwd)
-
-Sets the current working directory for the command.
-
-#### options.templateData
-
-type: `Object`
-
-The data that can be accessed in template.
-
-#### options.maxBuffer
-
-type: `Number`
-
-default: 16MB(16 * 1024 * 1024)
-
-You won't need to set this option unless you encounter a "stdout maxBuffer exceeded" error.
-
-#### options.env
-
-type: `Object`
-
-default: [`process.env`](http://nodejs.org/api/process.html#process_process_env) with `PATH` prepended by `./node_modules/.bin`, allowing you to run executables in your Node's dependencies.

+#### options.env
+

+
+By default, all the commands will be executed in an environment with all the variables in [`process.env`](http://nodejs.org/api/process.html#process_process_env) and `PATH` prepended by `./node_modules/.bin` (allowing you to run executables in your Node's dependencies).
+
+You can override any environment variables with this option.
+
+For example, setting it to `{PATH: process.env.PATH}` will reset the `PATH` if the default one brings your some troubles.

-# Async.js
-
-[![Build Status via Travis CI](https://travis-ci.org/caolan/async.svg?branch=master)](https://travis-ci.org/caolan/async)
-
-
-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), it can also be used directly in the
-browser. Also supports [component](https://github.com/component/component).
-
-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
-
-### 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.
-});
-```

-### each(arr, iterator, callback)
-
-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 occured, the `callback` should be run without 
-  arguments or with an explicit `null` argument.
-* `callback(err)` - 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');
-    }
-});
-```
-
----------------------------------------
-
-<a name="forEachSeries" />
-<a name="eachSeries" />
-### eachSeries(arr, iterator, callback)
-
-The same as [`each`](#each), only `iterator` is applied to each item in `arr` in
-series. The next `iterator` is only called once the current one has completed. 
-This means the `iterator` functions will complete in order.
-
-
----------------------------------------
-
-<a name="forEachLimit" />
-<a name="eachLimit" />
-### eachLimit(arr, limit, iterator, callback)
-
-The same as [`each`](#each), only no more than `limit` `iterator`s will be simultaneously 
-running at any time.
-
-Note that the items in `arr` are not processed in batches, so there is no guarantee that 
-the first `limit` `iterator` functions will complete before any others are started.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `limit` - The maximum number of `iterator`s to run at any time.
-* `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 occured, the callback should be run without 
-  arguments or with an explicit `null` argument.
-* `callback(err)` - A callback which is called when all `iterator` functions
-  have finished, or an error occurs.
-
-__Example__
-
-```js
-// Assume documents is an array of JSON objects and requestApi is a
-// function that interacts with a rate-limited REST api.
-
-async.eachLimit(documents, 20, requestApi, function(err){
-    // if any of the saves produced an error, err would equal that error
-});
-```
-
----------------------------------------
-
-<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 this 
-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)` - 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
-async.map(['file1','file2','file3'], fs.stat, function(err, results){
-    // results is now an array of stats for each file
-});
-```
-
----------------------------------------
-
-<a name="mapSeries" />
-### mapSeries(arr, iterator, callback)
-
-The same as [`map`](#map), only the `iterator` is applied to each item in `arr` in
-series. The next `iterator` is only called once the current one has completed. 
-The results array will be in the same order as the original.
-
-
----------------------------------------
-
-<a name="mapLimit" />
-### mapLimit(arr, limit, iterator, callback)
-
-The same as [`map`](#map), only no more than `limit` `iterator`s will be simultaneously 
-running at any time.
-
-Note that the items are not processed in batches, so there is no guarantee that 
-the first `limit` `iterator` functions will complete before any others are started.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `limit` - The maximum number of `iterator`s to run at any time.
-* `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)` - A callback which is called when all `iterator`
-  calls have finished, or an error occurs. The result is an array of the
-  transformed items from the original `arr`.
-
-__Example__
-
-```js
-async.mapLimit(['file1','file2','file3'], 1, fs.stat, function(err, results){
-    // results is now an array of stats for each file
-});
-```
-
----------------------------------------
-
-<a name="select" />
-<a name="filter" />
-### filter(arr, iterator, callback)
-
-__Alias:__ `select`
-
-Returns a new array of all the values in `arr` which pass an async truth test.
-_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
-way node libraries work with truth tests like `fs.exists`. This operation is
-performed in parallel, but the results array will be in the same order as the
-original.
-
-__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)` - A callback which is called after all the `iterator`
-  functions have finished.
-
-__Example__
-
-```js
-async.filter(['file1','file2','file3'], fs.exists, function(results){
-    // results now equals an array of the existing files
-});
-```
-
----------------------------------------
-
-<a name="selectSeries" />
-<a name="filterSeries" />
-### filterSeries(arr, iterator, callback)
-
-__Alias:__ `selectSeries`
-
-The same as [`filter`](#filter) only the `iterator` is applied to each item in `arr` in
-series. The next `iterator` is only called once the current one has completed. 
-The results array will be in the same order as the original.
-
----------------------------------------
-
-<a name="reject" />
-### reject(arr, iterator, callback)
-
-The opposite of [`filter`](#filter). Removes values that pass an `async` truth test.
-
----------------------------------------
-
-<a name="rejectSeries" />
-### rejectSeries(arr, iterator, callback)
-
-The same as [`reject`](#reject), only the `iterator` is applied to each item in `arr`
-in series.
-
-
----------------------------------------
-
-<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)` - 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)
-    });
-}, function(err, result){
-    // result is now equal to the last value of memo, which is 6
-});
-```
-
----------------------------------------
-
-<a name="reduceRight" />
-### reduceRight(arr, memo, iterator, callback)
-
-__Alias:__ `foldr`
-
-Same as [`reduce`](#reduce), only operates on `arr` in reverse order.
-
-
----------------------------------------
-
-<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.
-* `callback(result)` - 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.
-
-__Example__
-
-```js
-async.detect(['file1','file2','file3'], fs.exists, function(result){
-    // result now equals the first file in the list that exists
-});
-```
-
----------------------------------------
-
-<a name="detectSeries" />
-### detectSeries(arr, iterator, callback)
-
-The same as [`detect`](#detect), only the `iterator` is applied to each item in `arr`
-in series. This means the result is always the first in the original `arr` (in
-terms of array order) that passes the truth test.
-
-
----------------------------------------
-
-<a name="sortBy" />
-### 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)` - 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){
-    fs.stat(file, function(err, stats){
-        callback(err, stats.mtime);
-    });
-}, function(err, results){
-    // results is now the original array of files sorted by
-    // modified date
-});
-```
-
-__Sort Order__
-
-By modifying the callback parameter the sorting order can be influenced:
-
-```js
-//ascending order
-async.sortBy([1,9,3,5], function(x, callback){
-    callback(err, x);
-}, function(err,result){
-    //result callback
-} );
-
-//descending order
-async.sortBy([1,9,3,5], function(x, callback){
-    callback(err, x*-1);    //<- x*-1 instead of x, turns the order around
-}, function(err,result){
-    //result callback
-} );
-```
-
----------------------------------------
-
-<a name="some" />
-### some(arr, iterator, callback)
-
-__Alias:__ `any`
-
-Returns `true` if at least one element in the `arr` satisfies an async test.
-_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
-way node libraries work with truth tests like `fs.exists`. Once any iterator
-call returns `true`, the main `callback` is immediately called.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `iterator(item, callback)` - A truth test to apply to each item in the array
-  in parallel. The iterator is passed a callback(truthValue) which must be 
-  called with a boolean argument once it has completed.
-* `callback(result)` - A callback which is called as soon as any iterator returns
-  `true`, or after all the iterator functions have finished. Result will be
-  either `true` or `false` depending on the values of the async tests.
-
-__Example__
-
-```js
-async.some(['file1','file2','file3'], fs.exists, function(result){
-    // if result is true then at least one of the files exists
-});
-```
-
----------------------------------------
-
-<a name="every" />
-### every(arr, iterator, callback)
-
-__Alias:__ `all`
-
-Returns `true` if every element in `arr` satisfies an async test.
-_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
-way node libraries work with truth tests like `fs.exists`.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `iterator(item, callback)` - A truth test to apply to each item in the array
-  in parallel. The iterator is passed a callback(truthValue) which must be 
-  called with a  boolean argument once it has completed.
-* `callback(result)` - A callback which is called after all the `iterator`
-  functions have finished. Result will be either `true` or `false` depending on
-  the values of the async tests.
-
-__Example__
-
-```js
-async.every(['file1','file2','file3'], fs.exists, function(result){
-    // if result is true then every file exists
-});
-```
-
----------------------------------------
-
-<a name="concat" />
-### concat(arr, iterator, callback)
-
-Applies `iterator` to each item in `arr`, concatenating the results. Returns the
-concatenated list. The `iterator`s are called in parallel, and the results are
-concatenated as they return. There is no guarantee that the results array will
-be returned in the original order of `arr` passed to the `iterator` function.
-
-__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, results)` which must be called once it 
-  has completed with an error (which can be `null`) and an array of results.
-* `callback(err, results)` - A callback which is called after all the `iterator`
-  functions have finished, or an error occurs. Results is an array containing
-  the concatenated results of the `iterator` function.
-
-__Example__
-
-```js
-async.concat(['dir1','dir2','dir3'], fs.readdir, function(err, files){
-    // files is now a list of filenames that exist in the 3 directories
-});
-```
-
----------------------------------------
-
-<a name="concatSeries" />
-### concatSeries(arr, iterator, callback)
-
-Same as [`concat`](#concat), but executes in series instead of parallel.
-
-
-## 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 Specifcation](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__
-
-```js
-async.series([
-    function(callback){
-        // do some stuff ...
-        callback(null, 'one');
-    },
-    function(callback){
-        // do some more stuff ...
-        callback(null, 'two');
-    }
-],
-// optional callback
-function(err, results){
-    // results is now equal to ['one', 'two']
-});
-
-
-// an example using an object instead of an array
-async.series({
-    one: function(callback){
-        setTimeout(function(){
-            callback(null, 1);
-        }, 200);
-    },
-    two: function(callback){
-        setTimeout(function(){
-            callback(null, 2);
-        }, 100);
-    }
-},
-function(err, results) {
-    // results is now equal to: {one: 1, two: 2}
-});
-```
-
----------------------------------------
-
-<a name="parallel" />
-### parallel(tasks, [callback])
-
-Run the `tasks` array of functions in parallel, without waiting until the previous
-function has completed. If any of the functions pass an error to 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.
-
-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
-[`parallel`](#parallel).
-
-
-__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. This function gets a results array (or object) containing all 
-  the result arguments passed to the task callbacks.
-
-__Example__
-
-```js
-async.parallel([
-    function(callback){
-        setTimeout(function(){
-            callback(null, 'one');
-        }, 200);
-    },
-    function(callback){
-        setTimeout(function(){
-            callback(null, 'two');
-        }, 100);
-    }
-],
-// optional callback
-function(err, results){
-    // the results array will equal ['one','two'] even though
-    // the second function had a shorter timeout.
-});
-
-
-// an example using an object instead of an array
-async.parallel({
-    one: function(callback){
-        setTimeout(function(){
-            callback(null, 1);
-        }, 200);
-    },
-    two: function(callback){
-        setTimeout(function(){
-            callback(null, 2);
-        }, 100);
-    }
-},
-function(err, results) {
-    // results is now equals to: {one: 1, two: 2}
-});
-```

-
-<a name="parallelLimit" />
-### parallelLimit(tasks, limit, [callback])
-
-The same as [`parallel`](#parallel), only `tasks` are executed in parallel 
-with a maximum of `limit` tasks executing at any time.
-
-Note that the `tasks` are not executed in batches, so there is no guarantee that 
-the first `limit` tasks will complete before any others are started.
-
-__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.
-* `limit` - The maximum number of `tasks` to run at any time.
-* `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.
-
----------------------------------------
-
-<a name="whilst" />
-### whilst(test, fn, callback)
-
-Repeatedly call `fn`, while `test` returns `true`. Calls `callback` when stopped,
-or an error occurs.
-
-__Arguments__
-
-* `test()` - synchronous truth test to perform before each execution of `fn`.
-* `fn(callback)` - A function which is called each time `test` passes. The function is
-  passed a `callback(err)`, which must be called once it has completed with an 
-  optional `err` argument.
-* `callback(err)` - A callback which is called after the test fails and repeated
-  execution of `fn` has stopped.
-
-__Example__
-
-```js
-var count = 0;
-
-async.whilst(
-    function () { return count < 5; },
-    function (callback) {
-        count++;
-        setTimeout(callback, 1000);
-    },
-    function (err) {
-        // 5 seconds have passed
-    }
-);
-```
-
----------------------------------------
-
-<a name="doWhilst" />
-### doWhilst(fn, test, callback)
-
-The post-check version of [`whilst`](#whilst). To reflect the difference in 
-the order of operations, the arguments `test` and `fn` are switched. 
-
-`doWhilst` is to `whilst` as `do while` is to `while` in plain JavaScript.
-
----------------------------------------
-
-<a name="until" />
-### until(test, fn, callback)
-
-Repeatedly call `fn` until `test` returns `true`. Calls `callback` when stopped,
-or an error occurs.
-
-The inverse of [`whilst`](#whilst).
-
----------------------------------------
-
-<a name="doUntil" />
-### doUntil(fn, test, callback)
-
-Like [`doWhilst`](#doWhilst), except the `test` is inverted. Note the argument ordering differs from `until`.
-
----------------------------------------
-
-<a name="forever" />
-### forever(fn, errback)
-
-Calls the asynchronous function `fn` with a callback parameter that allows it to
-call itself again, in series, indefinitely.
-
-If an error is passed to the callback then `errback` is called with the
-error, and execution stops, otherwise it will never be called.
-
-```js
-async.forever(
-    function(next) {
-        // next is suitable for passing to things that need a callback(err [, whatever]);
-        // it will result in this function being called again.
-    },
-    function(err) {
-        // if next is called with a value in its first parameter, it will appear
-        // in here as 'err', and execution will stop.
-    }
-);
-```
-
----------------------------------------
-
-<a name="waterfall" />
-### waterfall(tasks, [callback])
-
-Runs the `tasks` array of functions in series, each passing their results to the next in
-the array. However, if any of the `tasks` pass an error to their own callback, the
-next function is not executed, and the main `callback` is immediately called with
-the error.
-
-__Arguments__
-
-* `tasks` - An array of functions to run, each function is passed a 
-  `callback(err, result1, result2, ...)` it must call on completion. The first
-  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'    
-});
-```
-
----------------------------------------
-<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);
-}
-
-var add1mul3 = async.compose(mul3, add1);
-
-add1mul3(4, function (err, result) {
-   // result now equals 15
-});
-```
-
----------------------------------------
-<a name="seq" />
-### seq(fn1, fn2...)
-
-Version of the compose function that is more natural to read.
-Each following function consumes the return value of the latter function. 
-
-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) {
-  function handleError(err, data, callback) {
-    if (err) {
-      console.error(err);
-      response.json({ status: 'error', message: err.message });
-    }
-    else {
-      callback(data);
-    }
-  }
-  var User = request.models.User;
-  async.seq(
-    _.bind(User.get, User),  // 'User.get' has signature (id, callback(err, data))
-    handleError,
-    function(user, fn) {
-      user.getCats(fn);      // 'getCats' has signature (callback(err, data))
-    },
-    handleError,
-    function(cats) {
-      response.json({ status: 'ok', message: 'Cats found', data: cats });

-  )(req.session.user_id);
-  }
-});
-```
-
----------------------------------------
-<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);
-
-// partial application example:
-async.each(
-    buckets,
-    async.applyEach([enableSearch, updateSchema]),
-    callback
-);
-```
-
----------------------------------------
-
-<a name="applyEachSeries" />
-### applyEachSeries(arr, iterator, callback)
-
-The same as [`applyEach`](#applyEach) only the functions are applied in series.
-
----------------------------------------
-
-<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.
-* `concurrency` - An `integer` for determining how many `worker` functions should be
-  run in parallel.
-
-__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.
-* `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 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 bar');
-});
-
-// 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.
-Check out [this animation](https://camo.githubusercontent.com/6bbd36f4cf5b35a0f11a96dcd2e97711ffc2fb37/68747470733a2f2f662e636c6f75642e6769746875622e636f6d2f6173736574732f313637363837312f36383130382f62626330636662302d356632392d313165322d393734662d3333393763363464633835382e676966) for how `cargo` and `queue` work.
-
-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`.
-
-__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, [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, it will not 
-complete (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.
-* `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([times = 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 successfull task. If all attemps fail, the callback will be passed the error and
-result (if any) of the final attempt.
-
-__Arguments__
-
-* `times` - An integer indicating how many times to attempt the `task` before giving up. Defaults to 5.
-* `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
-async.retry(3, apiMethod, function(err, result) {
-    // do something with the result
-});
-```
-
-It can also be embeded 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

----------------------------------------
-
-<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)
-
-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, callback)
-
-Calls the `callback` 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.
-* `callback` - The function to call `n` times.
-
-__Example__
-
-```js
-// Pretend this is some complicated async factory
-var createUser = function(id, callback) {
-  callback(null, {
-    id: 'user' + id
-  })
-}
-// generate 5 users
-async.times(5, function(n, next){
-    createUser(n, function(err, user) {
-      next(err, user)
-    })
-}, function(err, users) {
-  // we should now have 5 users
-});
-```
-
-<a name="timesSeries" />
-### timesSeries(n, callback)
-
-The same as [`times`](#times), only the iterator is applied to each item in `arr` in
-series. The next `iterator` is only called once the current one has completed. 
-The results array will be in the same order as the original.
-
-
-## Utils
-
-<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.
-
-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` - Tn 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="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.
+# Async.js
+
+[![Build Status via Travis CI](https://travis-ci.org/caolan/async.svg?branch=master)](https://travis-ci.org/caolan/async)
+
+
+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.
+
+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`
+- [spm](http://spmjs.io/): `spm 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
+
+### 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.
+});
+```

+### each(arr, iterator, callback)
+
+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.
+* `callback(err)` - 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');
+    }
+});

+### eachSeries(arr, iterator, callback)
+
+The same as [`each`](#each), only `iterator` is applied to each item in `arr` in

+### eachLimit(arr, limit, iterator, callback)
+
+The same as [`each`](#each), only no more than `limit` `iterator`s will be simultaneously 
+running at any time.
+
+Note that the items in `arr` are not processed in batches, so there is no guarantee that 
+the first `limit` `iterator` functions will complete before any others are started.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `limit` - The maximum number of `iterator`s to run at any time.
+* `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.
+* `callback(err)` - A callback which is called when all `iterator` functions
+  have finished, or an error occurs.
+
+__Example__
+
+```js
+// Assume documents is an array of JSON objects and requestApi is a
+// function that interacts with a rate-limited REST api.

+    // if any of the saves produced an error, err would equal that error
+});
+```
+
+---------------------------------------
+
+<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 his 
+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)` - 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
+async.map(['file1','file2','file3'], fs.stat, function(err, results){

+
+Note that the items are not processed in batches, so there is no guarantee that 
+the first `limit` `iterator` functions will complete before any others are started.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `limit` - The maximum number of `iterator`s to run at any time.
+* `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)` - A callback which is called when all `iterator`
+  calls have finished, or an error occurs. The result is an array of the
+  transformed items from the original `arr`.
+
+__Example__
+
+```js
+async.mapLimit(['file1','file2','file3'], 1, fs.stat, function(err, results){
+    // results is now an array of stats for each file

+```
+
+---------------------------------------
+
+<a name="select" />
+<a name="filter" />
+### filter(arr, iterator, callback)
+
+__Alias:__ `select`
+
+Returns a new array of all the values in `arr` which pass an async truth test.
+_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
+way node libraries work with truth tests like `fs.exists`. This operation is
+performed in parallel, but the results array will be in the same order as the
+original.
+
+__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)` - A callback which is called after all the `iterator`
+  functions have finished.
+
+__Example__
+
+```js
+async.filter(['file1','file2','file3'], fs.exists, function(results){
+    // results now equals an array of the existing files
+});
+```
+
+---------------------------------------
+
+<a name="selectSeries" />
+<a name="filterSeries" />
+### filterSeries(arr, iterator, callback)
+
+__Alias:__ `selectSeries`
+
+The same as [`filter`](#filter) only the `iterator` is applied to each item in `arr` in
+series. The next `iterator` is only called once the current one has completed. 
+The results array will be in the same order as the original.
+
+---------------------------------------
+
+<a name="reject" />
+### reject(arr, iterator, callback)
+
+The opposite of [`filter`](#filter). Removes values that pass an `async` truth test.
+
+---------------------------------------
+
+<a name="rejectSeries" />
+### rejectSeries(arr, iterator, callback)
+
+The same as [`reject`](#reject), only the `iterator` is applied to each item in `arr`
+in series.
+
+
+---------------------------------------
+
+<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)` - 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)
+    });
+}, function(err, result){
+    // result is now equal to the last value of memo, which is 6
+});
+```
+
+---------------------------------------
+
+<a name="reduceRight" />
+### reduceRight(arr, memo, iterator, callback)
+
+__Alias:__ `foldr`
+
+Same as [`reduce`](#reduce), only operates on `arr` in reverse order.
+
+
+---------------------------------------
+
+<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.
+* `callback(result)` - 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.
+
+__Example__
+
+```js
+async.detect(['file1','file2','file3'], fs.exists, function(result){
+    // result now equals the first file in the list that exists
+});
+```
+
+---------------------------------------
+
+<a name="detectSeries" />
+### detectSeries(arr, iterator, callback)
+
+The same as [`detect`](#detect), only the `iterator` is applied to each item in `arr`
+in series. This means the result is always the first in the original `arr` (in
+terms of array order) that passes the truth test.
+
+
+---------------------------------------
+
+<a name="sortBy" />
+### 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)` - 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){
+    fs.stat(file, function(err, stats){
+        callback(err, stats.mtime);
+    });
+}, function(err, results){
+    // results is now the original array of files sorted by
+    // modified date
+});
+```
+
+__Sort Order__
+
+By modifying the callback parameter the sorting order can be influenced:
+
+```js
+//ascending order
+async.sortBy([1,9,3,5], function(x, callback){
+    callback(null, x);
+}, function(err,result){
+    //result callback
+} );
+
+//descending order
+async.sortBy([1,9,3,5], function(x, callback){
+    callback(null, x*-1);    //<- x*-1 instead of x, turns the order around
+}, function(err,result){
+    //result callback
+} );
+```

+<a name="some" />
+### some(arr, iterator, callback)
+
+__Alias:__ `any`
+
+Returns `true` if at least one element in the `arr` satisfies an async test.
+_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
+way node libraries work with truth tests like `fs.exists`. Once any iterator
+call returns `true`, the main `callback` is immediately called.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in the array
+  in parallel. The iterator is passed a callback(truthValue) which must be 
+  called with a boolean argument once it has completed.
+* `callback(result)` - A callback which is called as soon as any iterator returns
+  `true`, or after all the iterator functions have finished. Result will be
+  either `true` or `false` depending on the values of the async tests.
+
+__Example__
+
+```js

+<a name="concat" />
+### concat(arr, iterator, callback)
+
+Applies `iterator` to each item in `arr`, concatenating the results. Returns the
+concatenated list. The `iterator`s are called in parallel, and the results are
+concatenated as they return. There is no guarantee that the results array will
+be returned in the original order of `arr` passed to the `iterator` function.
+
+__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, results)` which must be called once it 
+  has completed with an error (which can be `null`) and an array of results.
+* `callback(err, results)` - A callback which is called after all the `iterator`
+  functions have finished, or an error occurs. Results is an array containing
+  the concatenated results of the `iterator` function.
+
+__Example__
+
+```js
+async.concat(['dir1','dir2','dir3'], fs.readdir, function(err, files){
+    // files is now a list of filenames that exist in the 3 directories
+});

+
+Same as [`concat`](#concat), but executes in series instead of parallel.
+
+
+## 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 Specifcation](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__
+
+```js
+async.series([
+    function(callback){
+        // do some stuff ...
+        callback(null, 'one');
+    },

+
+---------------------------------------
+
+<a name="parallel" />
+### parallel(tasks, [callback])
+
+Run the `tasks` array of functions in parallel, without waiting until the previous
+function has completed. If any of the functions pass an error to 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.
+
+It is also possible to use an object instead of an array. Each property will be

+  (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

+
+<a name="parallelLimit" />
+### parallelLimit(tasks, limit, [callback])
+
+The same as [`parallel`](#parallel), only `tasks` are executed in parallel 
+with a maximum of `limit` tasks executing at any time.
+
+Note that the `tasks` are not executed in batches, so there is no guarantee that 
+the first `limit` tasks will complete before any others are started.
+
+__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.
+* `limit` - The maximum number of `tasks` to run at any time.

+
+<a name="whilst" />
+### whilst(test, fn, callback)
+
+Repeatedly call `fn`, while `test` returns `true`. Calls `callback` when stopped,
+or an error occurs.
+
+__Arguments__
+
+* `test()` - synchronous truth test to perform before each execution of `fn`.
+* `fn(callback)` - A function which is called each time `test` passes. The function is
+  passed a `callback(err)`, which must be called once it has completed with an 
+  optional `err` argument.
+* `callback(err)` - A callback which is called after the test fails and repeated
+  execution of `fn` has stopped.
+
+__Example__
+
+```js
+var count = 0;
+
+async.whilst(
+    function () { return count < 5; },

+
+---------------------------------------
+

+<a name="forever" />
+### forever(fn, errback)
+
+Calls the asynchronous function `fn` with a callback parameter that allows it to
+call itself again, in series, indefinitely.
+
+If an error is passed to the callback then `errback` is called with the
+error, and execution stops, otherwise it will never be called.
+
+```js
+async.forever(
+    function(next) {
+        // next is suitable for passing to things that need a callback(err [, whatever]);
+        // it will result in this function being called again.
+    },
+    function(err) {
+        // if next is called with a value in its first parameter, it will appear

+    }
+);
+```
+
+---------------------------------------
+
+<a name="waterfall" />
+### waterfall(tasks, [callback])
+
+Runs the `tasks` array of functions in series, each passing their results to the next in
+the array. However, if any of the `tasks` pass an error to their own callback, the
+next function is not executed, and the main `callback` is immediately called with
+the error.
+
+__Arguments__
+
+* `tasks` - An array of functions to run, each function is passed a 
+  `callback(err, result1, result2, ...)` it must call on completion. The first
+  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');

+<a name="compose" />
+### compose(fn1, fn2...)
+
+Creates a function which is a composition of the passed asynchronous

+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 () {

+
+Each function is executed with the `this` binding of the composed function.
+
+__Arguments__

+
+__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

+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

+
+<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.
+* `concurrency` - An `integer` for determining how many `worker` functions should be
+  run in parallel.
+
+__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.
+* `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() {

+
+// 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

+
+
+---------------------------------------
+
+<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.
+Check out [this animation](https://camo.githubusercontent.com/6bbd36f4cf5b35a0f11a96dcd2e97711ffc2fb37/68747470733a2f2f662e636c6f75642e6769746875622e636f6d2f6173736574732f313637363837312f36383130382f62626330636662302d356632392d313165322d393734662d3333393763363464633835382e676966) for how `cargo` and `queue` work.
+
+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`.
+
+__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) {

+
+<a name="auto" />
+### auto(tasks, [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, it will not 
+complete (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.
+* `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([times = 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__
+
+* `times` - An integer indicating how many times to attempt the `task` before giving up. Defaults to 5.
+* `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
+async.retry(3, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+It can also be embeded 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, callback)
+
+Calls the `callback` 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.
+* `callback` - The function to call `n` times.
+
+__Example__
+
+```js
+// Pretend this is some complicated async factory
+var createUser = function(id, callback) {
+  callback(null, {
+    id: 'user' + id
+  })
+}
+// generate 5 users
+async.times(5, function(n, next){
+    createUser(n, function(err, user) {
+      next(err, user)
+    })
+}, function(err, users) {
+  // we should now have 5 users
+});
+```
+
+<a name="timesSeries" />
+### timesSeries(n, callback)
+
+The same as [`times`](#times), only the iterator is applied to each item in `arr` in
+series. The next `iterator` is only called once the current one has completed. 
+The results array will be in the same order as the original.
+
+
+## Utils
+
+<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.
+
+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` - Tn 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="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.

-<tr>
-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>
-<td>>= 0.9</td>

-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.cyan('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. Use the right colors for values. If you pass in multiple arguments it will join them by a space.
-
-```
-values (files, module names, etc.) = magenta
-numbers (times, counts, etc) = cyan
-```
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/');
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files){
-  
-  });
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});
-```

+
+
+## API
+

+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## Advanced usage
+
+By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `ansi.modifiers`
+- `ansi.colors`
+- `ansi.bgColors`
+
+
+###### Example
+
+```js
+console.log(ansi.colors.green.open);
+```

-> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
-
-
-## Install
-
-```sh
-$ npm install --save ansi-regex
-```
-
-
-## Usage
-
-```js
-var ansiRegex = require('ansi-regex');
-
-ansiRegex().test('\u001b[4mcake\u001b[0m');
-//=> true
-
-ansiRegex().test('cake');
-//=> false
-
-'\u001b[4mcake\u001b[0m'.match(ansiRegex());
-//=> ['\u001b[4m', '\u001b[0m']
-```
-
-*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

-> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
-
-
-## Install
-
-```sh
-$ npm install --save ansi-regex
-```
-
-
-## Usage
-
-```js
-var ansiRegex = require('ansi-regex');
-
-ansiRegex().test('\u001b[4mcake\u001b[0m');
-//=> true
-
-ansiRegex().test('cake');
-//=> false
-
-'\u001b[4mcake\u001b[0m'.match(ansiRegex());
-//=> ['\u001b[4m', '\u001b[0m']
-```
-
-*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

-> Terminal string styling done right
-
-[![Build Status](https://travis-ci.org/sindresorhus/chalk.svg?branch=master)](https://travis-ci.org/sindresorhus/chalk)
-![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)
-
-[colors.js](https://github.com/Marak/colors.js) is currently the most popular string styling module, but it has serious deficiencies like extending String.prototype which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
-
-**Chalk is a clean and focused alternative.**
-
-![screenshot](https://github.com/sindresorhus/ansi-styles/raw/master/screenshot.png)
-
-
-## Why
-
-- Highly performant
-- Doesn't extend String.prototype
-- Expressive API
-- Ability to nest styles
-- Clean and focused
-- Auto-detects color support
-- Actively maintained
-- [Used by 1000+ modules](https://npmjs.org/browse/depended/chalk)
-
-
-## Install
-
-```sh
-$ npm install --save chalk
-```
-
-
-## Usage
-
-Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
-
-```js
-var chalk = require('chalk');
-
-// style a string
-console.log(  chalk.blue('Hello world!')  );
-
-// combine styled and normal strings
-console.log(  chalk.blue('Hello'), 'World' + chalk.red('!')  );
-
-// compose multiple styles using the chainable API
-console.log(  chalk.blue.bgRed.bold('Hello world!')  );
-
-// pass in multiple arguments
-console.log(  chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz')  );
-
-// nest styles
-console.log(  chalk.red('Hello', chalk.underline.bgBlue('world') + '!')  );
-
-// nest styles of the same type even (color, underline, background)
-console.log(  chalk.green('I am a green line ' + chalk.blue('with a blue substring') + ' that becomes green again!')  );
-```
-
-Easily define your own themes.
-
-```js
-var chalk = require('chalk');
-var error = chalk.bold.red;
-console.log(error('Error!'));
-```
-
-Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
-
-```js
-var name = 'Sindre';
-console.log(chalk.green('Hello %s'), name);
-//=> Hello Sindre
-```
-
-
-## API
-
-### chalk.`<style>[.<style>...](string, [string...])`
-
-Example: `chalk.red.bold.underline('Hello', 'world');`
-
-Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter.
-
-Multiple arguments will be separated by space.
-
-### chalk.enabled
-
-Color support is automatically detected, but you can override it.
-
-### chalk.supportsColor
-
-Detect whether the terminal [supports color](https://github.com/sindresorhus/supports-color).
-
-Can be overridden by the user with the flags `--color` and `--no-color`.
-
-Used internally and handled for you, but exposed for convenience.
-
-### chalk.styles
-
-Exposes the styles as [ANSI escape codes](https://github.com/sindresorhus/ansi-styles).
-
-Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with yours.
-
-```js
-var chalk = require('chalk');
-
-console.log(chalk.styles.red);
-//=> {open: '\u001b[31m', close: '\u001b[39m'}
-
-console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
-```
-
-### chalk.hasColor(string)
-
-Check whether a string [has color](https://github.com/sindresorhus/has-ansi).
-
-### chalk.stripColor(string)
-
-[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.
-
-Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
-
-Example:
-
-```js
-var chalk = require('chalk');
-var styledString = getText();
-
-if (!chalk.supportsColor) {
-	styledString = chalk.stripColor(styledString);
-}
-```
-
-
-## Styles
-
-### General
-
-- `reset`
-- `bold`
-- `dim`
-- `italic` *(not widely supported)*
-- `underline`
-- `inverse`
-- `hidden`
-- `strikethrough` *(not widely supported)*
-
-### Text colors
-
-- `black`
-- `red`
-- `green`
-- `yellow`
-- `blue`
-- `magenta`
-- `cyan`
-- `white`

+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `Chalk.red.yellow.green` is equivalent to `Chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, but you can override it by setting the `enabled` property. You should however only do this in your own code as it applies globally to all chalk consumers.
+
+If you need to change this in a reusable module create a new instance:
+
+```js
+var ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/sindresorhus/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.

+
+console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
+```

+
+[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.
+
+Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
+
+Example:
+

+- `strikethrough` *(not widely supported)*
+
+### Colors

+
+## 256-colors
+
+Chalk does not support support anything other than the base eight colors, which guarantees it will work on all terminals and systems. Some terminals, specifically `xterm` compliant ones, will support the full range of 8-bit colors. For this the lower level [ansi-256-colors](https://github.com/jbnicolai/ansi-256-colors) package can be used.
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://bliker.github.io/cmder/) instead of `cmd.exe`.

-# dateformat
-
-A node.js package for Steven Levithan's excellent [dateFormat()][dateformat] function.
-
-## Modifications
-
-* Removed the `Date.prototype.format` method. Sorry folks, but extending native prototypes is for suckers.
-* Added a `module.exports = dateFormat;` statement at the bottom
-* Added the placeholder `N` to get the ISO 8601 numeric representation of the day of the week
-
-## Installation
-
-```bash
-$ npm install dateformat
-```
-
-## Usage
-
-As taken from Steven's post, modified to match the Modifications listed above:
-```js
-    var dateFormat = require('dateformat');
-    var now = new Date();
-
-    // Basic usage
-    dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
-    // Saturday, June 9th, 2007, 5:46:21 PM
-
-    // You can use one of several named masks
-    dateFormat(now, "isoDateTime");
-    // 2007-06-09T17:46:21
-
-    // ...Or add your own
-    dateFormat.masks.hammerTime = 'HH:MM! "Can\'t touch this!"';
-    dateFormat(now, "hammerTime");
-    // 17:46! Can't touch this!
-
-    // When using the standalone dateFormat function,
-    // you can also provide the date as a string
-    dateFormat("Jun 9 2007", "fullDate");
-    // Saturday, June 9, 2007
-
-    // Note that if you don't include the mask argument,
-    // dateFormat.masks.default is used
-    dateFormat(now);
-    // Sat Jun 09 2007 17:46:21
-
-    // And if you don't include the date argument,
-    // the current date and time is used
-    dateFormat();
-    // Sat Jun 09 2007 17:46:22
-
-    // You can also skip the date argument (as long as your mask doesn't
-    // contain any numbers), in which case the current date/time is used
-    dateFormat("longTime");
-    // 5:46:22 PM EST
-
-    // And finally, you can convert local time to UTC time. Simply pass in
-    // true as an additional argument (no argument skipping allowed in this case):
-    dateFormat(now, "longTime", true);
-    // 10:46:21 PM UTC
-
-    // ...Or add the prefix "UTC:" or "GMT:" to your mask.
-    dateFormat(now, "UTC:h:MM:ss TT Z");
-    // 10:46:21 PM UTC
-
-    // You can also get the ISO 8601 week of the year:
-    dateFormat(now, "W");
-    // 42
-
-    // and also get the ISO 8601 numeric representation of the day of the week:
-    dateFormat(now,"N");
-    // 6

+var fooApp = require('./');
+
+var cli = meow({
+	help: [
+		'Usage',
+		'  foo-app <input>'
+	].join('\n')
+});
+/*
+{
+	input: ['unicorns'],
+	flags: {rainbowCake: true},
+	...
+}
+*/
+
+fooApp(cli.input[0], cli.flags);
+```

-```
-
-# methods
-
-``` js
-var parseArgs = require('minimist')
-```
-
-## var argv = parseArgs(args, opts={})
-
-Return an argument object `argv` populated with the array arguments from `args`.
-
-`argv._` contains all the arguments that didn't have an option associated with
-them.
-
-Numeric-looking arguments will be returned as numbers unless `opts.string` or
-`opts.boolean` is set for that argument name.
-
-Any arguments after `'--'` will not be parsed and will end up in `argv._`.
-
-options can be:
-
-* `opts.string` - a string or array of strings argument names to always treat as
-strings
-* `opts.boolean` - a boolean, string or array of strings to always treat as
-booleans. if `true` will treat all double hyphenated arguments without equal signs
-as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
-* `opts.alias` - an object mapping string names to strings or arrays of string
-argument names to use as aliases
-* `opts.default` - an object mapping string argument names to default values
-* `opts.stopEarly` - when true, populate `argv._` with everything after the
-first non-option
-* `opts['--']` - when true, populate `argv._` with everything before the `--`
-and `argv['--']` with everything after the `--`. Here's an example:
-* `opts.unknown` - a function which is invoked with a command line parameter not
-defined in the `opts` configuration object. If the function returns `false`, the
-unknown option is not added to `argv`.
-
-```
-> require('./')('one two three -- four five --six'.split(' '), { '--': true })
-{ _: [ 'one', 'two', 'three' ],
-  '--': [ 'four', 'five', '--six' ] }
-```
-
-Note that with `opts['--']` set, parsing for arguments still stops after the
-`--`.

+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

-# multipipe
-
-A better `Stream#pipe` that creates duplex streams and lets you handle errors in one place.
-
-[![build status](https://secure.travis-ci.org/segmentio/multipipe.png)](http://travis-ci.org/segmentio/multipipe)
-
-## Example
-
-```js
-var pipe = require('multipipe');
-
-// pipe streams
-var stream = pipe(streamA, streamB, streamC);
-
-// centralized error handling
-stream.on('error', fn);
-
-// creates a new stream
-source.pipe(stream).pipe(dest);
-
-// optional callback on finish or error
-pipe(streamA, streamB, streamC, function(err){
-  // ...
-});
-```
-
-## Duplex streams
-
-  Write to the pipe and you'll really write to the first stream, read from the pipe and you'll read from the last stream.
-
-```js
-var stream = pipe(a, b, c);
-
-source
-  .pipe(stream)
-  .pipe(destination);
-```
-
-  In this example the flow of data is:
-
-  * source ->
-  * a ->
-  * b ->
-  * c ->
-  * destination
-
-## Error handling
-
-  Each `pipe` forwards the errors the streams it wraps emit, so you have one central place to handle errors:
-
-```js
-var stream = pipe(a, b, c);
-
-stream.on('error', function(err){
-  // called three times
-});
-
-a.emit('error', new Error);
-b.emit('error', new Error);
-c.emit('error', new Error);
-```
-
-## API
-
-### pipe(stream, ...)
-
-Pass a variable number of streams and each will be piped to the next one.
-
-A stream will be returned that wraps passed in streams in a way that errors will be forwarded and you can write to and/or read from it.
-
-Pass a function as last argument to be called on `error` or `finish` of the last stream.

-duplexer2 [![build status](https://travis-ci.org/deoxxa/duplexer2.png)](https://travis-ci.org/deoxxa/fork)
-=========
-
-Like duplexer (http://npm.im/duplexer) but using streams2.
-
-Overview
---------
-
-duplexer2 is a reimplementation of [duplexer](http://npm.im/duplexer) using the
-readable-stream API which is standard in node as of v0.10. Everything largely
-works the same.
-
-Installation
-------------
-
-Available via [npm](http://npmjs.org/):
-
-> $ npm install duplexer2
-
-Or via git:
-
-> $ git clone git://github.com/deoxxa/duplexer2.git node_modules/duplexer2
-
-API
----
-
-**duplexer2**
-
-Creates a new `DuplexWrapper` object, which is the actual class that implements
-most of the fun stuff. All that fun stuff is hidden. DON'T LOOK.
-
-```javascript
-duplexer2([options], writable, readable)
-```
-
-```javascript
-var duplex = duplexer2(new stream.Writable(), new stream.Readable());
-```
-
-Arguments
-
-* __options__ - an object specifying the regular `stream.Duplex` options, as
-  well as the properties described below.
-* __writable__ - a writable stream
-* __readable__ - a readable stream
-
-Options
-
-* __bubbleErrors__ - a boolean value that specifies whether to bubble errors
-  from the underlying readable/writable streams. Default is `true`.
-
-Example
--------
-
-Also see [example.js](https://github.com/deoxxa/duplexer2/blob/master/example.js).
-
-Code:
-
-```javascript
-var stream = require("stream");
-
-var duplexer2 = require("duplexer2");
-
-var writable = new stream.Writable({objectMode: true}),
-    readable = new stream.Readable({objectMode: true});
-
-writable._write = function _write(input, encoding, done) {
-  if (readable.push(input)) {
-    return done();
-  } else {
-    readable.once("drain", done);
-  }
-};
-
-readable._read = function _read(n) {
-  // no-op
-};
-
-// simulate the readable thing closing after a bit
-writable.once("finish", function() {
-  setTimeout(function() {
-    readable.push(null);
-  }, 500);
-});
-
-var duplex = duplexer2(writable, readable);
-
-duplex.on("data", function(e) {
-  console.log("got data", JSON.stringify(e));
-});
-
-duplex.on("finish", function() {
-  console.log("got finish event");
-});
-
-duplex.on("end", function() {
-  console.log("got end event");
-});
-
-duplex.write("oh, hi there", function() {
-  console.log("finished writing");
-});
-
-duplex.end(function() {
-  console.log("finished ending");
-});
-```
-
-Output:
-
-```
-got data "oh, hi there"
-finished writing
-got finish event
-finished ending
-got end event
-```

+var duplex = duplexer2(new stream.Writable(), new stream.Readable());
+```
+
+Arguments
+
+* __options__ - an object specifying the regular `stream.Duplex` options, as
+  well as the properties described below.
+* __writable__ - a writable stream
+* __readable__ - a readable stream
+
+Options
+
+* __bubbleErrors__ - a boolean value that specifies whether to bubble errors
+  from the underlying readable/writable streams. Default is `true`.
+
+Example
+-------
+
+Also see [example.js](https://github.com/deoxxa/duplexer2/blob/master/example.js).
+
+Code:
+
+```javascript
+var stream = require("stream");
+
+var duplexer2 = require("duplexer2");
+
+var writable = new stream.Writable({objectMode: true}),
+    readable = new stream.Readable({objectMode: true});
+
+writable._write = function _write(input, encoding, done) {
+  if (readable.push(input)) {
+    return done();
+  } else {
+    readable.once("drain", done);
+  }
+};
+
+readable._read = function _read(n) {
+  // no-op
+};
+
+// simulate the readable thing closing after a bit
+writable.once("finish", function() {
+  setTimeout(function() {
+    readable.push(null);
+  }, 500);
+});
+
+var duplex = duplexer2(writable, readable);
+
+duplex.on("data", function(e) {
+  console.log("got data", JSON.stringify(e));
+});
+
+duplex.on("finish", function() {
+  console.log("got finish event");
+});
+
+duplex.on("end", function() {
+  console.log("got end event");
+});
+
+duplex.write("oh, hi there", function() {
+  console.log("finished writing");
+});
+
+duplex.end(function() {
+  console.log("finished ending");
+});
+```
+
+Output:
+
+```
+got data "oh, hi there"
+finished writing
+got finish event
+finished ending
+got end event
+```

-This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
-
-If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
-
-**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
-
-**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

Alternative\nimplementation is a literal copy of standard one located in standalone\nmodule to avoid requiring of `util`. It also has a shim for old\nbrowsers with no `Object.create` support.\n\nWhile keeping you sure you are using standard `inherits`\nimplementation in node.js environment, it allows bundlers such as\n[browserify](https://github.com/substack/node-browserify) to not\ninclude full `util` package to your client code if all you need is\njust `inherits` function. It worth, because browser shim for `util`\npackage is large and `inherits` is often the single function you need\nfrom it.\n\nIt's recommended to use this package instead of\n`require('util').inherits` for any code that has chances to be used\nnot only in node.js but in browser too.\n\n## usage\n\n```js\nvar inherits = require('inherits');\n// then use exactly as the standard one\n```\n\n## note on version ~1.0\n\nVersion ~1.0 had completely different motivation and is not compatible\nneither with 2.0 nor with standard node.js `inherits`.\n\nIf you are using version ~1.0 and planning to switch to ~2.0, be\ncareful:\n\n* new version uses `super_` instead of `super` for referencing\n  superclass\n* new version overwrites current prototype while old one preserves any\n  existing fields on it\n",

+
+> ES6 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) ponyfill
+
+> Ponyfill: A polyfill that doesn't overwrite the native method
+
+
+## Install
+
+```sh
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+var objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, source, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

-**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
-
-Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
-
-Note: A **Streams3** version of through2 is available in npm with the tag `"1.0"` rather than `"latest"` so an `npm install through2` will get you the current Streams2 version (version number is 0.x.x). To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
-
-```js
-fs.createReadStream('ex.txt')
-  .pipe(through2(function (chunk, enc, callback) {
-    for (var i = 0; i < chunk.length; i++)
-      if (chunk[i] == 97)
-        chunk[i] = 122 // swap 'a' for 'z'
-
-    this.push(chunk)
-
-    callback()
-   }))
-  .pipe(fs.createWriteStream('out.txt'))
-```
-
-Or object streams:
-
-```js
-var all = []
-
-fs.createReadStream('data.csv')
-  .pipe(csv2())
-  .pipe(through2.obj(function (chunk, enc, callback) {
-    var data = {
-        name    : chunk[0]
-      , address : chunk[3]
-      , phone   : chunk[10]
-    }
-    this.push(data)
-
-    callback()
-  }))
-  .on('data', function (data) {
-    all.push(data)
-  })
-  .on('end', function () {
-    doSomethingSpecial(all)
-  })
-```
-
-Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
-
-## API
-
-<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
-
-Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
-
-### options
-
-The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
-
-The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2({ objectMode: true, allowHalfOpen: false },
-    function (chunk, enc, cb) {
-      cb(null, 'wut?') // note we can use the second argument on the callback
-                       // to provide data as an alternative to this.push('wut?')
-    }
-  )
-  .pipe(fs.createWriteStream('/tmp/wut.txt'))
-```
-
-### transformFunction
-
-The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
-
-To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
-
-Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
-
-If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
-
-### flushFunction
-
-The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2(
-    function (chunk, enc, cb) { cb(null, chunk) }, // transform is a noop
-    function (cb) { // flush function
-      this.push('tacking on an extra buffer to the end');
-      cb();
-    }
-  ))
-  .pipe(fs.createWriteStream('/tmp/wut.txt'));
-```
-
-<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
-
-Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
-
-```js
-var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
-  if (record.temp != null && record.unit = "F") {
-    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
-    record.unit = "C"
-  }
-  this.push(record)
-  callback()
-})
-
-// Create instances of FToC like so:
-var converter = new FToC()
-// Or:
-var converter = FToC()
-// Or specify/override options when you instantiate, if you prefer:
-var converter = FToC({objectMode: true})
-```

-This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
-
-If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
-
-**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
-
-**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

-
-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-Browser-friendly inheritance fully compatible with standard node.js
-[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
-
-This package exports standard `inherits` from node.js `util` module in
-node environment, but also provides alternative browser-friendly
-implementation through [browser
-field](https://gist.github.com/shtylman/4339901). Alternative
-implementation is a literal copy of standard one located in standalone
-module to avoid requiring of `util`. It also has a shim for old
-browsers with no `Object.create` support.
-
-While keeping you sure you are using standard `inherits`
-implementation in node.js environment, it allows bundlers such as
-[browserify](https://github.com/substack/node-browserify) to not
-include full `util` package to your client code if all you need is
-just `inherits` function. It worth, because browser shim for `util`
-package is large and `inherits` is often the single function you need
-from it.
-
-It's recommended to use this package instead of
-`require('util').inherits` for any code that has chances to be used
-not only in node.js but in browser too.
-
-## usage
-
-```js
-var inherits = require('inherits');
-// then use exactly as the standard one
-```
-
-## note on version ~1.0
-
-Version ~1.0 had completely different motivation and is not compatible
-neither with 2.0 nor with standard node.js `inherits`.
-
-If you are using version ~1.0 and planning to switch to ~2.0, be
-careful:
-
-* new version uses `super_` instead of `super` for referencing
-  superclass

Alternative\nimplementation is a literal copy of standard one located in standalone\nmodule to avoid requiring of `util`. It also has a shim for old\nbrowsers with no `Object.create` support.\n\nWhile keeping you sure you are using standard `inherits`\nimplementation in node.js environment, it allows bundlers such as\n[browserify](https://github.com/substack/node-browserify) to not\ninclude full `util` package to your client code if all you need is\njust `inherits` function. It worth, because browser shim for `util`\npackage is large and `inherits` is often the single function you need\nfrom it.\n\nIt's recommended to use this package instead of\n`require('util').inherits` for any code that has chances to be used\nnot only in node.js but in browser too.\n\n## usage\n\n```js\nvar inherits = require('inherits');\n// then use exactly as the standard one\n```\n\n## note on version ~1.0\n\nVersion ~1.0 had completely different motivation and is not compatible\nneither with 2.0 nor with standard node.js `inherits`.\n\nIf you are using version ~1.0 and planning to switch to ~2.0, be\ncareful:\n\n* new version uses `super_` instead of `super` for referencing\n  superclass\n* new version overwrites current prototype while old one preserves any\n  existing fields on it\n",

-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a",
-    b: 'c'
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }
-```

-
-var coffeeFile = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee",
-  contents: new Buffer("test = 123")
-});
-```
-
-### constructor(options)
-
-#### options.cwd
-
-Type: `String`  
-Default: `process.cwd()`
-
-#### options.base
-
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`  
-Default: `options.cwd`
-
-#### options.path
-
-Full path to the file.
-
-Type: `String`  
-Default: `null`
-
-#### options.stat
-
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`  
-Default: `null`
-
-#### options.contents
-
-File contents.
-
-Type: `Buffer, Stream, or null`  
-Default: `null`
-
-### isBuffer()
-
-Returns true if file.contents is a Buffer.
-
-### isStream()
-
-Returns true if file.contents is a Stream.
-
-### isNull()
-
-Returns true if file.contents is null.
-
-### clone()
-
-Returns a new File object with all attributes cloned. Custom attributes are deep-cloned.
-
-### pipe(stream[, opt])
-
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### relative
-
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee

+If opt.end is false, the destination stream will not be ended (same as node core).
+
+Returns the stream.
+
+### inspect()
+
+Returns a pretty String interpretation of the File. Useful for console.log.
+
+### relative
+
+Returns path.relative for the file base and file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.relative); // file.coffee
+```

+# clone
+
+[![build status](https://secure.travis-ci.org/pvorb/node-clone.png)](http://travis-ci.org/pvorb/node-clone)
+
+offers foolproof _deep cloning_ of variables in JavaScript.
+
+
+## Installation
+
+    npm install clone
+
+or
+
+    ender build clone
+
+
+## Example
+
+~~~ javascript
+var clone = require('clone');
+
+var a, b;
+
+a = { foo: { bar: 'baz' } };  // initial value of a
+
+b = clone(a);                 // clone a -> b
+a.foo.bar = 'foo';            // change a
+
+console.log(a);               // show a
+console.log(b);               // show b
+~~~
+
+This will print:
+
+~~~ javascript
+{ foo: { bar: 'foo' } }
+{ foo: { bar: 'baz' } }
+~~~
+
+**clone** masters cloning simple objects (even with custom prototype), arrays,
+Date objects, and RegExp objects. Everything is cloned recursively, so that you
+can clone dates in arrays in objects, for example.
+
+
+## API
+
+`clone(val, circular, depth)`
+
+  * `val` -- the value that you want to clone, any type allowed
+  * `circular` -- boolean
+
+    Call `clone` with `circular` set to `false` if you are certain that `obj`
+    contains no circular references. This will give better performance if needed.
+    There is no error if `undefined` or `null` is passed as `obj`.
+  * `depth` -- depth to which the object is to be cloned (optional,
+    defaults to infinity)
+
+`clone.clonePrototype(obj)`
+
+  * `obj` -- the object that you want to clone
+
+Does a prototype clone as
+[described by Oran Looney](http://oranlooney.com/functional-javascript/).
+
+
+## Circular References
+
+~~~ javascript
+var a, b;
+
+a = { hello: 'world' };
+
+a.myself = a;
+b = clone(a);
+
+console.log(b);
+~~~
+
+This will print:
+
+~~~ javascript
+{ hello: "world", myself: [Circular] }
+~~~
+
+So, `b.myself` points to `b`, not `a`. Neat!
+
+
+## Test
+
+    npm test
+
+
+## Caveat
+
+Some special objects like a socket or `process.stdout`/`stderr` are known to not
+be cloneable. If you find other objects that cannot be cloned, please [open an
+issue](https://github.com/pvorb/node-clone/issues/new).
+
+
+## Bugs and Issues
+
+If you encounter any bugs or issues, feel free to [open an issue at
+github](https://github.com/pvorb/node-clone/issues) or send me an email to
+<paul@vorba.ch>. I also always like to hear from you, if you’re using my code.

+# lodash v3.5.0
+
+The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash](https://lodash.com/) exported as [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) modules.
+
+Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli):
+```bash
+$ lodash modularize modern exports=node -o ./
+$ lodash modern -d -o ./index.js
+```
+
+## Installation
+
+Using npm:
+
+```bash
+$ {sudo -H} npm i -g npm
+$ npm i --save lodash
+```
+
+In Node.js/io.js:
+
+```js
+// load the modern build
+var _ = require('lodash');
+// or a method category
+var array = require('lodash/array');
+// or a method (great for smaller builds with browserify/webpack)
+var chunk = require('lodash/array/chunk');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/3.5.0-npm) for more details.
+
+**Note:**<br>
+Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.<br>
+Install [n_](https://www.npmjs.com/package/n_) for a REPL that includes lodash by default.
+
+## Module formats

-**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
-
-Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
-
-Note: A **Streams3** version of through2 is available in npm with the tag `"1.0"` rather than `"latest"` so an `npm install through2` will get you the current Streams2 version (version number is 0.x.x). To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations [here](http://www.nearform.com/nodecrunch/dont-use-nodes-core-stream-module).
-
-```js
-fs.createReadStream('ex.txt')
-  .pipe(through2(function (chunk, enc, callback) {
-
-    for (var i = 0; i < chunk.length; i++)
-      if (chunk[i] == 97)
-        chunk[i] = 122 // swap 'a' for 'z'
-
-    this.push(chunk)
-
-    callback()
-
-   }))
-  .pipe(fs.createWriteStream('out.txt'))
-```
-
-Or object streams:
-
-```js
-var all = []
-
-fs.createReadStream('data.csv')
-  .pipe(csv2())
-  .pipe(through2.obj(function (chunk, enc, callback) {
-
-    var data = {
-        name    : chunk[0]
-      , address : chunk[3]
-      , phone   : chunk[10]
-    }
-
-    this.push(data)
-
-    callback()
-
-  }))
-  .on('data', function (data) {
-    all.push(data)
-  })
-  .on('end', function () {
-    doSomethingSpecial(all)
-  })
-```
-
-Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
-
-## API
-
-<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
-
-Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
-
-### options
-
-The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
-
-The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2({ objectMode: true, allowHalfOpen: false }, function (chunk, enc, cb) {
-
-    this.push(new Buffer('wut?'))
-    cb()
-
-  })
-  .pipe(fs.createWriteStream('/tmp/wut.txt'))
-```
-
-### transformFunction
-
-The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
-
-To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
-
-If you **do not provide a `transformFunction`** then you will get a simple simple pass-through stream.
-
-### flushFunction
-
-The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
-
-<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
-
-Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
-
-```js
-var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
-  if (record.temp != null && record.unit = "F") {
-    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
-    record.unit = "C"
-  }
-  this.push(record)
-  callback()
-})
-
-// Create instances of FToC like so:
-var converter = new FToC()
-// Or:
-var converter = FToC()
-// Or specify/override options when you instantiate, if you prefer:
-var converter = FToC({objectMode: true})
-```

-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes presedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a"
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }

+# lodash v3.7.0
+
+The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash](https://lodash.com/) exported as [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) modules.
+
+Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli):
+```bash
+$ lodash modularize modern exports=node -o ./
+$ lodash modern -d -o ./index.js
+```
+
+## Installation
+
+Using npm:
+
+```bash
+$ {sudo -H} npm i -g npm
+$ npm i --save lodash
+```
+
+In Node.js/io.js:
+
+```js
+// load the modern build
+var _ = require('lodash');
+// or a method category
+var array = require('lodash/array');
+// or a method (great for smaller builds with browserify/webpack)
+var chunk = require('lodash/array/chunk');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/3.7.0-npm) for more details.
+
+**Note:**<br>
+Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.<br>
+Install [n_](https://www.npmjs.com/package/n_) for a REPL that includes lodash by default.
+

+ * Creates a `lodash` object which wraps `value` to enable implicit chaining.
+ * Methods that operate on and return arrays, collections, and functions can
+ * be chained together. Methods that return a boolean or single value will
+ * automatically end the chain returning the unwrapped value. Explicit chaining
+ * may be enabled using `_.chain`. The execution of chained methods is lazy,
+ * that is, execution is deferred until `_#value` is implicitly or explicitly
+ * called.
+ *
+ * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
+ * fusion is an optimization that merges iteratees to avoid creating intermediate
+ * arrays and reduce the number of iteratee executions.
+ *
+ * Chaining is supported in custom builds as long as the `_#value` method is
+ * directly or indirectly included in the build.
+ *
+ * In addition to lodash methods, wrappers have `Array` and `String` methods.
+ *
+ * The wrapper `Array` methods are:
+ * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`,
+ * `splice`, and `unshift`
+ *
+ * The wrapper `String` methods are:
+ * `replace` and `split`
+ *
+ * The wrapper methods that support shortcut fusion are:
+ * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
+ * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
+ * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
+ * and `where`
+ *
+ * The chainable wrapper methods are:
+ * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
+ * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
+ * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
+ * `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
+ * `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
+ * `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
+ * `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
+ * `keysIn`, `map`, `mapValues`, `matches`, `matchesProperty`, `memoize`,
+ * `merge`, `mixin`, `negate`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
+ * `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,
+ * `pullAt`, `push`, `range`, `rearg`, `reject`, `remove`, `rest`, `reverse`,
+ * `shuffle`, `slice`, `sort`, `sortBy`, `sortByAll`, `sortByOrder`, `splice`,
+ * `spread`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `tap`,

+ * `union`, `uniq`, `unshift`, `unzip`, `values`, `valuesIn`, `where`,
+ * `without`, `wrap`, `xor`, `zip`, and `zipObject`
+ *
+ * The wrapper methods that are **not** chainable by default are:
+ * `add`, `attempt`, `camelCase`, `capitalize`, `clone`, `cloneDeep`, `deburr`,
+ * `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`, `findKey`,
+ * `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`, `has`,

-   * Creates a `lodash` object which wraps the given value to enable intuitive
-   * method chaining.
-   *
-   * In addition to Lo-Dash methods, wrappers also have the following `Array` methods:
-   * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
-   * and `unshift`
-   *
-   * Chaining is supported in custom builds as long as the `value` method is
-   * implicitly or explicitly included in the build.
-   *
-   * The chainable wrapper functions are:
-   * `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`,
-   * `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`,
-   * `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`,
-   * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
-   * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
-   * `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`,
-   * `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`,
-   * `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`,
-   * `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`,
-   * `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`,
-   * and `zip`
-   *
-   * The non-chainable wrapper functions are:
-   * `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`,
-   * `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`,
-   * `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
-   * `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`,
-   * `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`, `join`,
-   * `lastIndexOf`, `mixin`, `noConflict`, `parseInt`, `pop`, `random`, `reduce`,
-   * `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`,
-   * `template`, `unescape`, `uniqueId`, and `value`
-   *
-   * The wrapper functions `first` and `last` return wrapped values when `n` is
-   * provided, otherwise they return unwrapped values.
-   *
-   * Explicit chaining can be enabled by using the `_.chain` method.
