In many ways, it is similar to JSLint and JSHint with a few exceptions: + +* ESLint uses [Espree](https://github.com/eslint/espree) for JavaScript parsing. +* ESLint uses an AST to evaluate patterns in code. +* ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime. + +## Installation + +You can install ESLint using npm: + + npm install -g eslint + +## Usage + + eslint test.js test2.js + +## Frequently Asked Questions + +### Why don't you like JSHint??? + +I do like JSHint. And I like Anton and Rick. Neither of those were deciding factors in creating this tool. The fact is that I've had a dire need for a JavaScript tool with pluggable linting rules. I had hoped JSHint would be able to do this, however after chatting with Anton, I found that the planned plugin infrastructure wasn't going to suit my purpose. + +### I'm not giving up JSHint for this! + +That's not really a question, but I got it. I'm not trying to convince you that ESLint is better than JSHint. The only thing I know is that ESLint is better than JSHint for what I'm doing. In the off chance you're doing something similar, it might be better for you. Otherwise, keep using JSHint, I'm certainly not going to tell you to stop using it. + +### How does ESLint performance compare to JSHint? + +ESLint is slower than JSHint, usually 2-3x slower on a single file. This is because ESLint uses Espree to construct an AST before it can evaluate your code whereas JSHint evaluates your code as it's being parsed. The speed is also based on the number of rules you enable; the more rules you enable, the slower the process. + +Despite being slower, we believe that ESLint is fast enough to replace JSHint without causing significant pain. + +### Is ESLint just linting or does it also check style? + +ESLint does both traditional linting (looking for problematic patterns) and style checking (enforcement of conventions). You can use it for both. + +### Who is using ESLint? + +The following projects are using ESLint to validate their JavaScript: + +* [Drupal](https://www.drupal.org/node/2274223) +* [Esprima](https://github.com/ariya/esprima) +* [WebKit](https://bugs.webkit.org/show_bug.cgi?id=125048) + +In addition, the following companies are using ESLint internally to validate their JavaScript: + +* [Box](https://box.com) +* [CustomInk](https://customink.com) +* [Fitbit](http://www.fitbit.com) +* [HolidayCheck](http://holidaycheck.de) +* [the native web](http://www.thenativeweb.io) + +### What about ECMAScript 6 support? + +We are implementing ECMAScript 6 support piece-by-piece starting with version 0.12.0.

+[![Build Status](https://travis-ci.org/estools/escope.png?branch=master)](https://travis-ci.org/estools/escope)
+
+### Example
+
+    var escope = require('escope');
+    var esprima = require('esprima');
+    var estraverse = require('estraverse');
+    
+    var ast = esprima.parse(code);

+    });
+
+### Document
+
+Generated JSDoc is [here](http://estools.github.io/escope/).
+
+### Demos and Tools
+
+Demonstration is [here](http://mazurov.github.io/escope-demo/) by [Sasha Mazurov](https://github.com/mazurov) (twitter: [@mazurov](http://twitter.com/mazurov)). [issue](https://github.com/estools/escope/issues/14)

+
+
+And there are tools constructed on Escope.
+
+- [Esmangle](https://github.com/estools/esmangle) is a minifier / mangler / optimizer.
+- [Eslevels](https://github.com/mazurov/eslevels) is a scope levels analyzer and [SublimeText plugin for scope context coloring](https://github.com/mazurov/sublime-levels) is constructed on it.
+- [Esgoggles](https://github.com/keeyipchan/esgoggles) is JavaScript code browser.

+# es6-map
+## Map collection as specified in ECMAScript6
+
+### Usage
+
+If you want to make sure your environment implements `Map`, do:
+
+```javascript
+require('es6-map/implement');
+```
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't, but without implementing `Map` on global scope, do:
+
+```javascript
+var Map = require('es6-map');
+```
+
+If you strictly want to use polyfill even if native `Map` exists, do:
+
+```javascript
+var Map = require('es6-map/polyfill');
+```
+
+### Installation
+
+	$ npm install es6-map
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-map-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Map = require('es6-map');
+
+var x = {}, y = {}, map = new Map([['raz', 'one'], ['dwa', 'two'], [x, y]]);
+
+map.size;                 // 3
+map.get('raz');           // 'one'
+map.get(x);               // y
+map.has('raz');           // true
+map.has(x);               // true
+map.has('foo');           // false
+map.set('trzy', 'three'); // map
+map.size                  // 4
+map.get('trzy');          // 'three'
+map.has('trzy');          // true
+map.has('dwa');           // true
+map.delete('dwa');        // true
+map.size;                 // 3
+
+map.forEach(function (value, key) {
+  // { 'raz', 'one' }, { x, y }, { 'trzy', 'three' } iterated
+});
+
+// FF nightly only:
+for (value of map) {
+ // ['raz', 'one'], [x, y], ['trzy', 'three'] iterated
+}
+
+var iterator = map.values();
+
+iterator.next(); // { done: false, value: 'one' }
+iterator.next(); // { done: false, value: y }
+iterator.next(); // { done: false, value: 'three' }
+iterator.next(); // { done: true, value: undefined }
+
+map.clear(); // undefined
+map.size; // 0
+```

+# D - Property descriptor factory
+
+_Originally derived from [es5-ext](https://github.com/medikoo/es5-ext) package._
+
+Defining properties with descriptors is very verbose:
+
+```javascript
+var Account = function () {};
+Object.defineProperties(Account.prototype, {
+  deposit: { value: function () {
+      /* ... */
+    }, configurable: true, enumerable: false, writable: true },
+  whithdraw: { value: function () {
+      /* ... */
+    }, configurable: true, enumerable: false, writable: true },
+  balance: { get: function () {
+      /* ... */
+    }, configurable: true, enumerable: false }
+});
+```
+
+D cuts that to:
+
+```javascript
+var d = require('d');
+
+var Account = function () {};
+Object.defineProperties(Account.prototype, {
+  deposit: d(function () {
+    /* ... */
+  }),
+  whithdraw: d(function () {
+    /* ... */
+  }),
+  balance: d.gs(function () {
+    /* ... */
+  })
+});
+```
+
+By default, created descriptor follow characteristics of native ES5 properties, and defines values as:
+
+```javascript
+{ configurable: true, enumerable: false, writable: true }
+```
+
+You can overwrite it by preceding _value_ argument with instruction:
+```javascript
+d('c', value); // { configurable: true, enumerable: false, writable: false }
+d('ce', value); // { configurable: true, enumerable: true, writable: false }
+d('e', value); // { configurable: false, enumerable: true, writable: false }
+
+// Same way for get/set:
+d.gs('e', value); // { configurable: false, enumerable: true }
+```
+
+### Other utilities
+
+#### autoBind(obj, props) _(d/auto-bind)_
+
+Define methods which will be automatically bound to its instances
+
+```javascript
+var d = require('d');
+var autoBind = require('d/auto-bind');
+
+var Foo = function () { this._count = 0; };
+autoBind(Foo.prototype, {
+  increment: d(function () { ++this._count; });
+});
+
+var foo = new Foo();
+
+// Increment foo counter on each domEl click
+domEl.addEventListener('click', foo.increment, false);
+```
+
+#### lazy(obj, props) _(d/lazy)_
+
+Define lazy properties, which will be resolved on first access
+
+```javascript
+var d = require('d');
+var lazy = require('d/lazy');
+
+var Foo = function () {};
+lazy(Foo.prototype, {
+  items: d(function () { return []; })
+});
+
+var foo = new Foo();
+foo.items.push(1, 2); // foo.items array created
+```
+
+## Installation
+### NPM
+
+In your project path:
+
+	$ npm install d
+
+### Browser
+
+You can easily bundle _D_ for browser with [modules-webmake](https://github.com/medikoo/modules-webmake)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/d.png)](https://travis-ci.org/medikoo/d)
+

+
+v0.10.2  --  2014.04.24
+- Simplify and deprecate `isCallable`. It seems in ES5 based engines there are
+  no callable objects which are `typeof obj !== 'function'`
+- Update Array.from map callback signature (up to latest resolution of TC39)
+- Improve documentation
+
+v0.10.1  --  2014.04.14
+Bump version for npm
+(Workaround for accidental premature publish & unpublish of v0.10.0 a while ago)
+
+v0.10.0  --  2014.04.13
+Major update:
+- All methods and function specified for ECMAScript 6 are now introduced as
+  shims accompanied with functions through which (optionally) they can be
+  implementend on native objects
+- Filename convention was changed to shorter and strictly lower case names. e.g.
+  `lib/String/prototype/starts-with` became `string/#/starts-with`
+- Generated functions are guaranteed to have expected length
+- Objects with null prototype (created via `Object.create(null)`) are widely
+  supported (older version have crashed due to implied `obj.hasOwnProperty` and
+  related invocations)
+- Support array subclasses
+- When handling lists do not limit its length to Uint32 range
+- Use newly introduced `Object.eq` for strict equality in place of `Object.is`
+- Iteration of Object have been improved so properties that were hidden or
+  removed after iteration started are not iterated.
+

+  handling, improve internals
+- `Array.prototype.find`: return undefined not null, in case of not found
+  (follow ES 6)

+* String#dashToCamelCase -> String#hyphenToCamel
+
+Fixes:
+* Object.isObject - Quote names in literals that match reserved keywords
+  (older implementations crashed on that)
+* String#repeat - Do not accept negative values (coerce them to 1)
+
+Improvements:
+* Array#remove - Accepts many arguments, we can now remove many values at once
+* Object iterators (forEach, map, some) - Compare function invoked with scope
+  object bound to this
+* Function#curry - Algorithm cleanup
+* Object.isCopy - Support for all types, not just plain objects
+* Object.isPlainObject - Support for cross-frame objects
+* Do not memoize any of the functions, it shouldn't be decided internally
+* Remove Object.freeze calls in reserved, it's not up to convention
+* Improved documentation
+* Better linting (hard-core approach using both JSLint mod and JSHint)
+* Optional arguments are now documented in funtions signature
+
+v0.8.2  --  2012.06.22
+Fix errors in Array's intersection and exclusion methods, related to improper
+usage of contains method
+
+v0.8.1  --  2012.06.13
+Reorganized internal logic of Function.prototype.memoize. So it's more safe now
+and clears cache properly. Additionally preventCache option was provided.
+
+v0.8.0  --  2012.05.28
+Again, major overhaul. Probably last experimental stuff was trashed, all API
+looks more like standard extensions now.
+
+Changes:
+* Turn all Object.prototype extensions into functions and move them to Object
+namespace. We learned that extending Object.prototype is bad idea in any case.
+* Rename Function.prototype.curry into Function.prototype.partial. This function
+  is really doing partial application while currying is slightly different
+  concept.
+* Convert Function.prototype.ncurry to new implementation of
+  Function.prototype.curry, it now serves real curry concept additionaly it
+  covers use cases for aritize and hold, which were removed.
+* Rename Array's peek to last, and provide support for sparse arrays in it
+* Rename Date's monthDaysCount into daysInMonth
+* Simplify object iterators, now order of iteration can be configured with just
+  compareFn argument (no extra byKeys option)
+* Rename Object.isDuplicate to Object.isCopy
+* Rename Object.isEqual to Object.is which is compatible with future 'is'
+  keyword
+* Function.memoize is now Function.prototype.memoize. Additionally clear cache
+  functionality is added, and access to original arguments object.
+* Rename validation functions: assertNotNull to validValue, assertCallable to
+  validCallable. validValue was moved to Object namespace. On success they now
+  return validated value instead of true, it supports better composition.
+  Additionally created Date.validDate and Error.validError
+* All documentation is now held in README.md not in code files.
+* Move guid to String namespace. All guids now start with numbers.
+* Array.generate: fill argument is now optional
+* Object.toArray is now Array.from (as new ES6 specification draft suggests)
+* All methods that rely on indexOf or lastIndexOf, now rely on egal (Object.is)
+  versions of them (eIndexOf, eLastIndexOf)
+* Turn all get* functions that returned methods into actuall methods (get*
+  functionality can still be achieved with help of Function.prototype.partial).
+  So: Date.getFormat is now Date.prototype.format,
+  Number.getPad is now Number.prototype.pad,
+  String.getFormat is now String.prototype.format,
+  String.getIndent is now String.prototype.indent,
+  String.getPad is now String.prototype.pad
+* Refactored Object.descriptor, it is now just two functions, main one and
+  main.gs, main is for describing values, and gs for describing getters and
+  setters. Configuration is passed with first argument as string e.g. 'ce' for
+  configurable and enumerable. If no configuration string is provided then by
+  default it returns configurable and writable but not enumerable for value or
+  configurable but not enumerable for getter/setter
+* Function.prototype.silent now returns prepared function (it was
+  expected to be fixed for 0.7)
+* Reserved keywords map (reserved) is now array not hash.
+* Object.merge is now Object.extend (while former Object.extend was completely
+  removed) - 'extend' implies that we change object, not creating new one (as
+  'merge' may imply). Similarily Object.mergeProperties was renamed to
+  Object.extendProperties
+* Position argument support in Array.prototype.contains and
+  String.prototype.contains (so it follows ES6 specification draft)
+* endPosition argument support in String.prototype.endsWith and fromPosition
+  argument support in String.prototype.startsWith (so it follows ES6
+  specification draft)
+* Better and cleaner String.prototype.indent implementation. No default value
+  for indent string argument, optional nest value (defaults to 1), remove
+  nostart argument
+* Correct length values for most methods (so they reflect length of similar
+  methods in standard)
+* Length argument is now optional in number and string pad methods.
+* Improve arguments validation in general, so it adheres to standard conventions
+* Fixed format of package.json
+
+Removed methods and functions:
+* Object.prototype.slice - Object is not ordered collection, so slice doesn't
+  make sense.
+* Function's rcurry, rncurry, s - too cumbersome for JS, not many use cases for
+  that
+* Function.prototype.aritize and Function.prototype.hold - same functionality
+  can be achieved with new Function.prototype.curry
+* Function.prototype.log - provided more generic Function.prototype.wrap for
+  same use case
+* getNextIdGenerator - no use case for that (String.guid should be used if
+  needed)
+* Object.toObject - Can be now acheived with Object(validValue(x))
+* Array.prototype.someValue - no real use case (personally used once and
+  case was already controversial)
+* Date.prototype.duration - moved to external package
+* Number.getAutoincrement - No real use case
+* Object.prototype.extend, Object.prototype.override,
+  Object.prototype.plainCreate, Object.prototype.plainExtend - It was probably
+  too complex, same should be achieved just with Object.create,
+  Object.descriptor and by saving references to super methods in local scope.
+* Object.getCompareBy - Functions should be created individually for each use
+  case
+* Object.get, Object.getSet, Object.set, Object.unset - Not many use cases and
+  same can be easily achieved with simple inline function
+* String.getPrefixWith - Not real use case for something that can be easily
+  achieved with '+' operator
+* Object.isPrimitive - It's just negation of Object.isObject
+* Number.prototype.isLess, Number.prototype.isLessOrEqual - they shouldn't be in
+  Number namespace and should rather be addressed with simple inline functions.
+* Number.prototype.subtract - Should rather be addressed with simple inline
+  function
+
+New methods and functions:
+* Array.prototype.lastIndex - Returns last declared index in array
+* String.prototype.last - last for strings
+* Function.prototype.wrap - Wrap function with other, it allows to specify
+  before and after behavior transform return value or prevent original function
+  from being called.
+* Math.sign - Returns sign of a number (already in ES6 specification draft)
+* Number.toInt - Converts value to integer (already in ES6 specification draft)
+* Number.isNaN - Returns true if value is NaN (already in ES6 specification
+  draft)
+* Number.toUint - Converts value to unsigned integer
+* Number.toUint32 - Converts value to 32bit unsigned integer
+* Array.prototype.eIndexOf, eLastIndexOf - Egal version (that uses Object.is) of
+  standard methods (all methods that were using native indexOf or lastIndexOf
+  now uses eIndexOf and elastIndexOf respectively)
+* Array.of - as it's specified for ES6
+
+Fixes:
+* Fixed binarySearch so it always returns valid list index
+* Object.isList - it failed on lists that are callable (e.g. NodeList in Nitro
+  engine)
+* Object.map now supports third argument for callback
+
+v0.7.1  --  2012.01.05
+New methods:
+* Array.prototype.firstIndex - returns first valid index of array (for
+	sparse arrays it may not be '0'
+
+Improvements:
+* Array.prototype.first - now returns value for index returned by firstIndex
+* Object.prototype.mapToArray - can be called without callback, then array of
+	key-value pairs is returned
+
+Fixes
+* Array.prototype.forEachRight, object's length read through UInt32 conversion
+
+v0.7.0  --  2011.12.27
+Major update.
+Stepped back from experimental ideas and introduced more standard approach
+taking example from how ES5 methods and functions are designed. One exceptions
+is that, we don’t refrain from declaring methods for Object.prototype - it’s up
+to developer whether how he decides to use it in his context (as function or as
+method).
+
+In general:
+* Removed any method 'functionalization' and functionalize method itself.
+	es5-ext declares plain methods, which can be configured to work as functions
+	with call.bind(method) - see documentation.
+* Removed separation of Object methods for ES5 (with descriptors) and
+	ES3 (plain) - we're following ES5 idea on that, some methods are intended just
+	for enumerable properties and some are for all properties, all are declared
+	for Object.prototype
+* Removed separation of Array generic (collected in List folder) and not generic
+	methods (collected in Array folder). Now all methods are generic and are in
+	Array/prototype folder. This separation also meant, that methods in Array are
+	usually destructive. We don’t do that separation now, there’s generally no use
+	case for destructive iterators, we should be fine with one version of each
+	method, (same as ES5 is fine with  e.g. one, non destructive 'filter' method)
+* Folder structure resembles tree of native ES5 Objects
+* All methods are written with ES5 conventions in mind, it means that most
+	methods are generic and can be run on any object. In more detail:
+	** Array.prototype and Object.prototype methods can be run on any object (any
+		not null or undefined value),
+	** Date.prototype methods should be called only on Date instances.
+	** Function.prototype methods can be called on any callable objects (not
+		necessarily functions)
+	** Number.prototype & String.prototype methods can be called on any value, in
+		case of Number it it’ll be degraded to number, in case of string it’ll be
+		degraded to string.
+* Travis CI support (only for Node v0.6 branch, as v0.4 has buggy V8 version)
+
+Improvements for existing functions and methods:
+* Function.memoize (was Function.cache) is now fully generic, can operate on any
+	type of arguments and it’s NaN safe (all NaN objects are considered equal)
+* Method properties passed to Object.prototype.extend or
+	Object.prototype.override can aside of _super optionally take prototype object
+	via _proto argument
+* Object iterators: forEach, mapToArray and every can now iterate in specified
+	order
+* pluck, invoke and other functions that return reusable functions or methods
+	have now their results memoized.
+
+New methods:
+* Global: assertNotNull, getNextIdGenerator, guid, isEqual, isPrimitive,
+	toObject
+* Array: generate
+* Array.prototype: binarySearch, clear, contains, diff, exclusion, find, first,
+	forEachRight, group, indexesOf, intersection, remove, someRight, someValue
+* Boolean: isBoolean
+* Date: isDate
+* Function: arguments, context, insert, isArguments, remove
+* Function.prototype: not, silent
+* Number: getAutoincrement, isNumber
+* Number.prototype: isLessOrEqual, isLess, subtract
+* Object: assertCallable, descriptor (functions for clean descriptors),
+	getCompareBy, isCallable, isObject
+* Object.prototype: clone (real clone), compact, count, diff, empty,
+	getPropertyNames, get, keyOf, mapKeys, override, plainCreate, plainExtend,
+	slice, some, unset
+* RegExp: isRegExp
+* String: getPrefixWith, isString
+* String.prototype: caseInsensitiveCompare, contains, isNumeric

+	objects
+* List.isList -> Object.isList
+* List.toArray -> Object.prototype.toArray
+* String/convert/dashToCamelCase -> String.prototype.dashToCamelCase

+# es5-ext
+## ECMAScript 5 extensions
+### (with respect to ECMAScript 6 standard)
+
+Shims for upcoming ES6 standard and other goodies implemented strictly with ECMAScript conventions in mind.
+
+It's designed to be used in compliant ECMAScript 5 or ECMAScript 6 environments. Older environments are not supported, although most of the features should work with correct ECMAScript 5 shim on board.
+
+When used in ECMAScript 6 environment, native implementation (if valid) takes precedence over shims.
+
+### Installation
+
+	$ npm install es5-ext
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+#### ECMAScript 6 features
+
+You can force ES6 features to be implemented in your environment, e.g. following will assign `from` function to `Array` (only if it's not implemented already).
+
+```javascript
+require('es5-ext/array/from/implement');
+Array.from('foo'); // ['f', 'o', 'o']
+```
+
+You can also access shims directly, without fixing native objects. Following will return native `Array.from` if it's available and fallback to shim if it's not.
+
+```javascript
+var aFrom = require('es5-ext/array/from');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+
+If you want to use shim unconditionally (even if native implementation exists) do:
+
+```javascript
+var aFrom = require('es5-ext/array/from/shim');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+

+
+#### Non ECMAScript standard features
+
+__es5-ext__ provides also other utils, and implements them as if they were proposed for a standard. It mostly offers methods (not functions) which can directly be assigned to native prototypes:
+
+```javascript
+Object.defineProperty(Function.prototype, 'partial', { value: require('es5-ext/function/#/partial'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(Array.prototype, 'flatten', { value: require('es5-ext/array/#/flatten'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(String.prototype, 'capitalize', { value: require('es5-ext/string/#/capitalize'),
+  configurable: true, enumerable: false, writable: true });
+```
+
+See [es5-extend](https://github.com/wookieb/es5-extend#es5-extend), a great utility that automatically will extend natives for you. 
+
+__Important:__ Remember to __not__ extend natives in scope of generic reusable packages (e.g. ones you intend to publish to npm). Extending natives is fine __only__ if you're the _owner_ of the global scope, so e.g. in final project you lead development of.
+
+When you're in situation when native extensions are not good idea, then you should use methods indirectly:
+
+
+```javascript
+var flatten = require('es5-ext/array/#/flatten');
+
+flatten.call([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+for better convenience you can turn methods into functions:
+
+
+```javascript
+var call = Function.prototype.call
+var flatten = call.bind(require('es5-ext/array/#/flatten'));
+
+flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+You can configure custom toolkit (like [underscorejs](http://underscorejs.org/)), and use it throughout your application
+
+```javascript
+var util = {};
+util.partial = call.bind(require('es5-ext/function/#/partial'));
+util.flatten = call.bind(require('es5-ext/array/#/flatten'));
+util.startsWith = call.bind(require('es5-ext/string/#/starts-with'));
+
+util.flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+As with native ones most methods are generic and can be run on any type of object.

+
+#### toArray(obj[, cb[, thisArg[, compareFn]]]) _(es5-ext/object/to-array)_
+
+Creates an array of results of calling a provided function on every key-value pair in this object.  
+Optionally _compareFn_ can be provided which assures that results are added in given order. If provided _compareFn_ is equal to `true`, then order is alphabetical (by key).
+
+#### unserialize(str) _(es5-ext/object/unserialize)_
+
+Userializes value previously serialized with [serialize](#serializevalue-es5-extobjectserialize)

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)

+# es6-iterator
+## ECMAScript 6 Iterator interface
+
+### Installation
+
+	$ npm install es6-iterator
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.
+

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)

+# es6-set
+## Set collection as specified in ECMAScript6
+
+### Usage
+
+If you want to make sure your environment implements `Set`, do:
+
+```javascript
+require('es6-set/implement');
+```
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't, but without implementing `Set` on global scope, do:
+
+```javascript
+var Set = require('es6-set');
+```
+
+If you strictly want to use polyfill even if native `Set` exists, do:
+
+```javascript
+var Set = require('es6-set/polyfill');
+```
+
+### Installation
+
+	$ npm install es6-set
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-set-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Set = require('es6-set');
+
+var set = new Set(['raz', 'dwa', {}]);
+
+set.size;          // 3
+set.has('raz');    // true
+set.has('foo');    // false
+set.add('foo');    // set
+set.size           // 4
+set.has('foo');    // true
+set.has('dwa');    // true
+set.delete('dwa'); // true
+set.size;          // 3
+
+set.forEach(function (value) {
+ // 'raz', {}, 'foo' iterated
+});
+
+// FF nightly only:
+for (value of set) {
+ // 'raz', {}, 'foo' iterated
+}
+
+var iterator = set.values();
+
+iterator.next(); // { done: false, value: 'raz' }
+iterator.next(); // { done: false, value: {} }
+iterator.next(); // { done: false, value: 'foo' }
+iterator.next(); // { done: true, value: undefined }
+
+set.clear(); // undefined
+set.size; // 0
+```
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-set.png)](https://travis-ci.org/medikoo/es6-set)

+# es6-symbol
+## ECMAScript6 Symbol polyfill
+
+### Limitations
+
+- Underneath it uses real string property names which can easily be retrieved (however accidental collision with other property names is unlikely)
+- As it needs custom `toString` behavior to work properly. Original `Symbol.prototype.toString` couldn't be implemented as specified, still it's accessible as `Symbol.prototoype.properToString`
+
+### Usage
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't, but without implementing `Symbol` on global scope, do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+You can easily bundle _es6-symbol_ for browser with [modules-webmake](https://github.com/medikoo/modules-webmake)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)
+
+	$ npm test

+v0.3.1  --  2014.04.25
+* Fix redefinition of emit method in `pipe`
+* Allow custom emit method name in `pipe`
+
+v0.3.0  --  2014.04.24
+* Move out from lib folder
+* Do not expose all utilities on main module
+* Support objects which do not inherit from Object.prototype
+* Improve arguments validation
+* Improve internals
+* Remove Makefile
+* Improve documentation
+
+v0.2.2  --  2013.06.05
+* `unify` functionality
+
+v0.2.1  --  2012.09.21
+* hasListeners module
+* Simplified internal id (improves performance a little), now it starts with
+  underscore (hint it's private). Abstracted it to external module to have it
+  one place
+* Documentation cleanup
+
+v0.2.0  --  2012.09.19
+* Trashed poor implementation of v0.1 and came up with something solid
+
+Changes:
+* Improved performance
+* Fixed bugs event-emitter is now cross-prototype safe and not affected by
+  unexpected methods attached to Object.prototype
+* Removed support for optional "emitter" argument in `emit` method, it was
+  cumbersome to use, and should be solved just with event objects
+
+v0.1.5  --  2012.08.06
+* (maintanance) Do not use descriptors for internal objects, it exposes V8 bugs
+  (only Node v0.6 branch)
+
+v0.1.4  --  2012.06.13
+* Fix detachment of listeners added with 'once'
+
+v0.1.3  --  2012.05.28
+* Updated es5-ext to latest version (v0.8)
+* Cleared package.json so it's in npm friendly format
+
+v0.1.2  --  2012.01.22
+* Support for emitter argument in emit function, this allows some listeners not
+  to be notified about event
+* allOff - removes all listeners from object
+* All methods returns self object
+* Internal fixes
+* Travis CI integration
+
+v0.1.1  --  2011.08.08
+* Added TAD test suite to devDependencies, configured test commands.
+  Tests can be run with 'make test' or 'npm test'
+
+v0.1.0  --  2011.08.08

+# event-emitter
+## Environment agnostic event emitter
+
+### Installation
+
+	$ npm install event-emitter
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+```javascript
+var ee = require('event-emitter');
+
+var emitter = ee({}), listener;
+
+emitter.on('test', listener = function (args) {
+  // …emitter logic
+});
+
+emitter.once('test', function (args) {
+  // …invoked only once(!)
+});
+
+emitter.emit('test', arg1, arg2/*…args*/); // Two above listeners invoked
+emitter.emit('test', arg1, arg2/*…args*/); // Only first listener invoked
+
+emitter.off('test', listener);              // Removed first listener
+emitter.emit('test', arg1, arg2/*…args*/); // No listeners invoked
+```
+### Additional utilities
+
+#### allOff(obj) _(event-emitter/all-off)_
+
+Removes all listeners from given event emitter object
+
+#### hasListeners(obj[, name]) _(event-emitter/has-listeners)_
+
+Whether object has some listeners attached to the object.
+When `name` is provided, it checks listeners for specific event name
+
+```javascript
+var emitter = ee();
+var hasListeners = require('event-emitter/has-listeners');
+var listener = function () {};
+
+hasListeners(emitter); // false
+
+emitter.on('foo', listener);
+hasListeners(emitter); // true
+hasListeners(emitter, 'foo'); // true
+hasListeners(emitter, 'bar'); // false
+
+emitter.off('foo', listener);
+hasListeners(emitter, 'foo'); // false
+```
+
+#### pipe(source, target[, emitMethodName]) _(event-emitter/pipe)_
+
+Pipes all events from _source_ emitter onto _target_ emitter (all events from _source_ emitter will be emitted also on _target_ emitter, but not other way).  
+Returns _pipe_ object which exposes `pipe.close` function. Invoke it to close configured _pipe_.  
+It works internally by redefinition of `emit` method, if in your interface this method is referenced differently, provide its name (or symbol) with third argument.
+
+#### unify(emitter1, emitter2) _(event-emitter/unify)_
+
+Unifies event handling for two objects. Events emitted on _emitter1_ would be also emitter on _emitter2_, and other way back.  
+Non reversible.
+
+```javascript
+var eeUnify = require('event-emitter/unify');
+
+var emitter1 = ee(), listener1, listener3;
+var emitter2 = ee(), listener2, listener4;
+
+emitter1.on('test', listener1 = function () { });
+emitter2.on('test', listener2 = function () { });
+
+emitter1.emit('test'); // Invoked listener1
+emitter2.emit('test'); // Invoked listener2
+
+var unify = eeUnify(emitter1, emitter2);
+
+emitter1.emit('test'); // Invoked listener1 and listener2
+emitter2.emit('test'); // Invoked listener1 and listener2
+
+emitter1.on('test', listener3 = function () { });
+emitter2.on('test', listener4 = function () { });
+
+emitter1.emit('test'); // Invoked listener1, listener2, listener3 and listener4
+emitter2.emit('test'); // Invoked listener1, listener2, listener3 and listener4
+```

+# es6-weak-map
+## WeakMap collection as specified in ECMAScript6
+
+_Roughly inspired by Mark Miller's and Kris Kowal's [WeakMap implementation](https://github.com/drses/weak-map)_.
+
+Differences are:
+- Assumes compliant ES5 environment (no weird ES3 workarounds or hacks)
+- Well modularized CJS style
+- Based on one solution.
+
+### Limitations
+
+- Will fail on non extensible objects provided as keys
+- While `clear` method is provided, it's not perfectly spec compliant. If some objects were saved as _values_, they need to be removed via `delete`. Otherwise they'll remain infinitely attached to _key_ object (that means, they'll be free for GC only if _key_ object was collected as well).
+
+### Installation
+
+	$ npm install es6-weak-map
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+If you want to make sure your environment implements `WeakMap`, do:
+
+```javascript
+require('es6-weak-map/implement');
+```
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't, but without implementing `WeakMap` on global scope, do:
+
+```javascript
+var WeakMap = require('es6-weak-map');
+```
+
+If you strictly want to use polyfill even if native `WeakMap` exists, do:
+
+```javascript
+var WeakMap = require('es6-weak-map/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-weakmap-objects). Still if you want quick look, follow example:
+
+```javascript
+var WeakMap = require('es6-weak-map');
+
+var map = new WeakMap();
+var obj = {};
+
+map.set(obj, 'foo'); // map
+map.get(obj);        // 'foo'
+map.has(obj);        // true
+map.delete(obj);     // true
+map.get(obj);        // undefined
+map.has(obj);        // false
+map.set(obj, 'bar'); // map
+map.clear();         // undefined
+map.has(obj);        // false
+```
+

+# D - Property descriptor factory
+
+_Originally derived from [es5-ext](https://github.com/medikoo/es5-ext) package._
+
+Defining properties with descriptors is very verbose:
+
+```javascript
+var Account = function () {};
+Object.defineProperties(Account.prototype, {
+  deposit: { value: function () {
+      /* ... */
+    }, configurable: true, enumerable: false, writable: true },
+  whithdraw: { value: function () {
+      /* ... */
+    }, configurable: true, enumerable: false, writable: true },
+  balance: { get: function () {
+      /* ... */
+    }, configurable: true, enumerable: false }
+});
+```
+
+D cuts that to:
+
+```javascript
+var d = require('d');
+
+var Account = function () {};
+Object.defineProperties(Account.prototype, {
+  deposit: d(function () {
+    /* ... */
+  }),
+  whithdraw: d(function () {
+    /* ... */
+  }),
+  balance: d.gs(function () {
+    /* ... */
+  })
+});
+```
+
+By default, created descriptor follow characteristics of native ES5 properties, and defines values as:
+
+```javascript
+{ configurable: true, enumerable: false, writable: true }
+```
+
+You can overwrite it by preceding _value_ argument with instruction:
+```javascript
+d('c', value); // { configurable: true, enumerable: false, writable: false }
+d('ce', value); // { configurable: true, enumerable: true, writable: false }
+d('e', value); // { configurable: false, enumerable: true, writable: false }
+
+// Same way for get/set:
+d.gs('e', value); // { configurable: false, enumerable: true }
+```
+
+### Other utilities
+
+#### autoBind(obj, props) _(d/auto-bind)_
+
+Define methods which will be automatically bound to its instances
+
+```javascript
+var d = require('d');
+var autoBind = require('d/auto-bind');
+
+var Foo = function () { this._count = 0; };
+autoBind(Foo.prototype, {
+  increment: d(function () { ++this._count; });
+});
+
+var foo = new Foo();
+
+// Increment foo counter on each domEl click
+domEl.addEventListener('click', foo.increment, false);
+```
+
+#### lazy(obj, props) _(d/lazy)_
+
+Define lazy properties, which will be resolved on first access
+
+```javascript
+var d = require('d');
+var lazy = require('d/lazy');
+
+var Foo = function () {};
+lazy(Foo.prototype, {
+  items: d(function () { return []; })
+});
+
+var foo = new Foo();
+foo.items.push(1, 2); // foo.items array created
+```
+
+## Installation
+### NPM
+
+In your project path:
+
+	$ npm install d
+
+### Browser
+
+You can easily bundle _D_ for browser with [modules-webmake](https://github.com/medikoo/modules-webmake)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/d.png)](https://travis-ci.org/medikoo/d)
+
+	$ npm test

+v0.10.2  --  2014.04.24
+- Simplify and deprecate `isCallable`. It seems in ES5 based engines there are
+  no callable objects which are `typeof obj !== 'function'`
+- Update Array.from map callback signature (up to latest resolution of TC39)
+- Improve documentation
+
+v0.10.1  --  2014.04.14
+Bump version for npm
+(Workaround for accidental premature publish & unpublish of v0.10.0 a while ago)
+
+v0.10.0  --  2014.04.13
+Major update:
+- All methods and function specified for ECMAScript 6 are now introduced as
+  shims accompanied with functions through which (optionally) they can be
+  implementend on native objects
+- Filename convention was changed to shorter and strictly lower case names. e.g.
+  `lib/String/prototype/starts-with` became `string/#/starts-with`
+- Generated functions are guaranteed to have expected length
+- Objects with null prototype (created via `Object.create(null)`) are widely
+  supported (older version have crashed due to implied `obj.hasOwnProperty` and
+  related invocations)
+- Support array subclasses
+- When handling lists do not limit its length to Uint32 range
+- Use newly introduced `Object.eq` for strict equality in place of `Object.is`
+- Iteration of Object have been improved so properties that were hidden or
+  removed after iteration started are not iterated.

+
+v0.9.1  --  2012.09.17
+* Object.reduce - reduce for hash-like collections
+* Accapt any callable object as callback in Object.filter, mapKeys and map
+* Convention cleanup
+
+v0.9.0  --  2012.09.13
+We're getting to real solid API
+
+Removed:
+* Function#memoize - it's grown up to be external package, to be soon published
+  as 'memoizee'
+* String.guid - it doesn't fit es5-ext (extensions) concept, will be provided as
+  external package
+# Function.arguments - obsolete
+# Function.context - obsolete
+# Function#flip - not readable when used, so it was never used
+# Object.clone - obsolete and confusing
+
+Added:
+* String#camelToHyphen - String format convertion
+
+Renamed:
+* String#dashToCamelCase -> String#hyphenToCamel
+
+Fixes:
+* Object.isObject - Quote names in literals that match reserved keywords
+  (older implementations crashed on that)
+* String#repeat - Do not accept negative values (coerce them to 1)
+
+Improvements:
+* Array#remove - Accepts many arguments, we can now remove many values at once
+* Object iterators (forEach, map, some) - Compare function invoked with scope
+  object bound to this
+* Function#curry - Algorithm cleanup
+* Object.isCopy - Support for all types, not just plain objects
+* Object.isPlainObject - Support for cross-frame objects
+* Do not memoize any of the functions, it shouldn't be decided internally
+* Remove Object.freeze calls in reserved, it's not up to convention
+* Improved documentation
+* Better linting (hard-core approach using both JSLint mod and JSHint)
+* Optional arguments are now documented in funtions signature
+
+v0.8.2  --  2012.06.22
+Fix errors in Array's intersection and exclusion methods, related to improper
+usage of contains method
+
+v0.8.1  --  2012.06.13
+Reorganized internal logic of Function.prototype.memoize. So it's more safe now
+and clears cache properly. Additionally preventCache option was provided.
+
+v0.8.0  --  2012.05.28
+Again, major overhaul. Probably last experimental stuff was trashed, all API
+looks more like standard extensions now.
+
+Changes:
+* Turn all Object.prototype extensions into functions and move them to Object
+namespace. We learned that extending Object.prototype is bad idea in any case.
+* Rename Function.prototype.curry into Function.prototype.partial. This function
+  is really doing partial application while currying is slightly different
+  concept.
+* Convert Function.prototype.ncurry to new implementation of
+  Function.prototype.curry, it now serves real curry concept additionaly it
+  covers use cases for aritize and hold, which were removed.
+* Rename Array's peek to last, and provide support for sparse arrays in it
+* Rename Date's monthDaysCount into daysInMonth
+* Simplify object iterators, now order of iteration can be configured with just
+  compareFn argument (no extra byKeys option)
+* Rename Object.isDuplicate to Object.isCopy
+* Rename Object.isEqual to Object.is which is compatible with future 'is'
+  keyword
+* Function.memoize is now Function.prototype.memoize. Additionally clear cache
+  functionality is added, and access to original arguments object.
+* Rename validation functions: assertNotNull to validValue, assertCallable to
+  validCallable. validValue was moved to Object namespace. On success they now
+  return validated value instead of true, it supports better composition.
+  Additionally created Date.validDate and Error.validError
+* All documentation is now held in README.md not in code files.
+* Move guid to String namespace. All guids now start with numbers.
+* Array.generate: fill argument is now optional
+* Object.toArray is now Array.from (as new ES6 specification draft suggests)
+* All methods that rely on indexOf or lastIndexOf, now rely on egal (Object.is)
+  versions of them (eIndexOf, eLastIndexOf)
+* Turn all get* functions that returned methods into actuall methods (get*
+  functionality can still be achieved with help of Function.prototype.partial).
+  So: Date.getFormat is now Date.prototype.format,
+  Number.getPad is now Number.prototype.pad,
+  String.getFormat is now String.prototype.format,
+  String.getIndent is now String.prototype.indent,
+  String.getPad is now String.prototype.pad
+* Refactored Object.descriptor, it is now just two functions, main one and
+  main.gs, main is for describing values, and gs for describing getters and
+  setters. Configuration is passed with first argument as string e.g. 'ce' for
+  configurable and enumerable. If no configuration string is provided then by
+  default it returns configurable and writable but not enumerable for value or
+  configurable but not enumerable for getter/setter
+* Function.prototype.silent now returns prepared function (it was
+  expected to be fixed for 0.7)
+* Reserved keywords map (reserved) is now array not hash.
+* Object.merge is now Object.extend (while former Object.extend was completely
+  removed) - 'extend' implies that we change object, not creating new one (as
+  'merge' may imply). Similarily Object.mergeProperties was renamed to
+  Object.extendProperties
+* Position argument support in Array.prototype.contains and
+  String.prototype.contains (so it follows ES6 specification draft)
+* endPosition argument support in String.prototype.endsWith and fromPosition
+  argument support in String.prototype.startsWith (so it follows ES6
+  specification draft)
+* Better and cleaner String.prototype.indent implementation. No default value
+  for indent string argument, optional nest value (defaults to 1), remove
+  nostart argument
+* Correct length values for most methods (so they reflect length of similar
+  methods in standard)
+* Length argument is now optional in number and string pad methods.
+* Improve arguments validation in general, so it adheres to standard conventions
+* Fixed format of package.json
+
+Removed methods and functions:
+* Object.prototype.slice - Object is not ordered collection, so slice doesn't
+  make sense.
+* Function's rcurry, rncurry, s - too cumbersome for JS, not many use cases for
+  that
+* Function.prototype.aritize and Function.prototype.hold - same functionality
+  can be achieved with new Function.prototype.curry
+* Function.prototype.log - provided more generic Function.prototype.wrap for
+  same use case
+* getNextIdGenerator - no use case for that (String.guid should be used if
+  needed)
+* Object.toObject - Can be now acheived with Object(validValue(x))
+* Array.prototype.someValue - no real use case (personally used once and
+  case was already controversial)
+* Date.prototype.duration - moved to external package
+* Number.getAutoincrement - No real use case
+* Object.prototype.extend, Object.prototype.override,
+  Object.prototype.plainCreate, Object.prototype.plainExtend - It was probably
+  too complex, same should be achieved just with Object.create,
+  Object.descriptor and by saving references to super methods in local scope.
+* Object.getCompareBy - Functions should be created individually for each use
+  case
+* Object.get, Object.getSet, Object.set, Object.unset - Not many use cases and
+  same can be easily achieved with simple inline function
+* String.getPrefixWith - Not real use case for something that can be easily
+  achieved with '+' operator
+* Object.isPrimitive - It's just negation of Object.isObject
+* Number.prototype.isLess, Number.prototype.isLessOrEqual - they shouldn't be in
+  Number namespace and should rather be addressed with simple inline functions.
+* Number.prototype.subtract - Should rather be addressed with simple inline
+  function
+
+New methods and functions:
+* Array.prototype.lastIndex - Returns last declared index in array
+* String.prototype.last - last for strings
+* Function.prototype.wrap - Wrap function with other, it allows to specify
+  before and after behavior transform return value or prevent original function
+  from being called.
+* Math.sign - Returns sign of a number (already in ES6 specification draft)
+* Number.toInt - Converts value to integer (already in ES6 specification draft)
+* Number.isNaN - Returns true if value is NaN (already in ES6 specification
+  draft)
+* Number.toUint - Converts value to unsigned integer
+* Number.toUint32 - Converts value to 32bit unsigned integer
+* Array.prototype.eIndexOf, eLastIndexOf - Egal version (that uses Object.is) of
+  standard methods (all methods that were using native indexOf or lastIndexOf
+  now uses eIndexOf and elastIndexOf respectively)
+* Array.of - as it's specified for ES6
+
+Fixes:
+* Fixed binarySearch so it always returns valid list index
+* Object.isList - it failed on lists that are callable (e.g. NodeList in Nitro
+  engine)
+* Object.map now supports third argument for callback
+
+v0.7.1  --  2012.01.05
+New methods:
+* Array.prototype.firstIndex - returns first valid index of array (for
+	sparse arrays it may not be '0'
+
+Improvements:
+* Array.prototype.first - now returns value for index returned by firstIndex
+* Object.prototype.mapToArray - can be called without callback, then array of
+	key-value pairs is returned
+
+Fixes
+* Array.prototype.forEachRight, object's length read through UInt32 conversion
+
+v0.7.0  --  2011.12.27
+Major update.
+Stepped back from experimental ideas and introduced more standard approach
+taking example from how ES5 methods and functions are designed. One exceptions
+is that, we don’t refrain from declaring methods for Object.prototype - it’s up
+to developer whether how he decides to use it in his context (as function or as
+method).
+
+In general:
+* Removed any method 'functionalization' and functionalize method itself.
+	es5-ext declares plain methods, which can be configured to work as functions
+	with call.bind(method) - see documentation.
+* Removed separation of Object methods for ES5 (with descriptors) and
+	ES3 (plain) - we're following ES5 idea on that, some methods are intended just
+	for enumerable properties and some are for all properties, all are declared
+	for Object.prototype
+* Removed separation of Array generic (collected in List folder) and not generic
+	methods (collected in Array folder). Now all methods are generic and are in
+	Array/prototype folder. This separation also meant, that methods in Array are
+	usually destructive. We don’t do that separation now, there’s generally no use
+	case for destructive iterators, we should be fine with one version of each
+	method, (same as ES5 is fine with  e.g. one, non destructive 'filter' method)
+* Folder structure resembles tree of native ES5 Objects
+* All methods are written with ES5 conventions in mind, it means that most
+	methods are generic and can be run on any object. In more detail:
+	** Array.prototype and Object.prototype methods can be run on any object (any
+		not null or undefined value),
+	** Date.prototype methods should be called only on Date instances.
+	** Function.prototype methods can be called on any callable objects (not
+		necessarily functions)
+	** Number.prototype & String.prototype methods can be called on any value, in
+		case of Number it it’ll be degraded to number, in case of string it’ll be
+		degraded to string.
+* Travis CI support (only for Node v0.6 branch, as v0.4 has buggy V8 version)
+
+Improvements for existing functions and methods:
+* Function.memoize (was Function.cache) is now fully generic, can operate on any
+	type of arguments and it’s NaN safe (all NaN objects are considered equal)
+* Method properties passed to Object.prototype.extend or
+	Object.prototype.override can aside of _super optionally take prototype object
+	via _proto argument
+* Object iterators: forEach, mapToArray and every can now iterate in specified
+	order
+* pluck, invoke and other functions that return reusable functions or methods
+	have now their results memoized.
+
+New methods:
+* Global: assertNotNull, getNextIdGenerator, guid, isEqual, isPrimitive,
+	toObject
+* Array: generate
+* Array.prototype: binarySearch, clear, contains, diff, exclusion, find, first,
+	forEachRight, group, indexesOf, intersection, remove, someRight, someValue
+* Boolean: isBoolean
+* Date: isDate
+* Function: arguments, context, insert, isArguments, remove
+* Function.prototype: not, silent

+* Object.prototype: clone (real clone), compact, count, diff, empty,
+	getPropertyNames, get, keyOf, mapKeys, override, plainCreate, plainExtend,
+	slice, some, unset
+* RegExp: isRegExp
+* String: getPrefixWith, isString
+* String.prototype: caseInsensitiveCompare, contains, isNumeric

+# es5-ext
+## ECMAScript 5 extensions
+### (with respect to ECMAScript 6 standard)
+
+Shims for upcoming ES6 standard and other goodies implemented strictly with ECMAScript conventions in mind.
+
+It's designed to be used in compliant ECMAScript 5 or ECMAScript 6 environments. Older environments are not supported, although most of the features should work with correct ECMAScript 5 shim on board.
+
+When used in ECMAScript 6 environment, native implementation (if valid) takes precedence over shims.
+
+### Installation
+
+	$ npm install es5-ext
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+#### ECMAScript 6 features
+
+You can force ES6 features to be implemented in your environment, e.g. following will assign `from` function to `Array` (only if it's not implemented already).
+
+```javascript
+require('es5-ext/array/from/implement');
+Array.from('foo'); // ['f', 'o', 'o']
+```
+
+You can also access shims directly, without fixing native objects. Following will return native `Array.from` if it's available and fallback to shim if it's not.
+
+```javascript
+var aFrom = require('es5-ext/array/from');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+
+If you want to use shim unconditionally (even if native implementation exists) do:
+
+```javascript
+var aFrom = require('es5-ext/array/from/shim');
+aFrom('foo'); // ['f', 'o', 'o']
+```

+
+#### Non ECMAScript standard features
+
+__es5-ext__ provides also other utils, and implements them as if they were proposed for a standard. It mostly offers methods (not functions) which can directly be assigned to native prototypes:
+
+```javascript
+Object.defineProperty(Function.prototype, 'partial', { value: require('es5-ext/function/#/partial'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(Array.prototype, 'flatten', { value: require('es5-ext/array/#/flatten'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(String.prototype, 'capitalize', { value: require('es5-ext/string/#/capitalize'),
+  configurable: true, enumerable: false, writable: true });
+```
+
+See [es5-extend](https://github.com/wookieb/es5-extend#es5-extend), a great utility that automatically will extend natives for you. 
+
+__Important:__ Remember to __not__ extend natives in scope of generic reusable packages (e.g. ones you intend to publish to npm). Extending natives is fine __only__ if you're the _owner_ of the global scope, so e.g. in final project you lead development of.
+
+When you're in situation when native extensions are not good idea, then you should use methods indirectly:
+
+
+```javascript
+var flatten = require('es5-ext/array/#/flatten');
+
+flatten.call([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+for better convenience you can turn methods into functions:
+
+
+```javascript
+var call = Function.prototype.call
+var flatten = call.bind(require('es5-ext/array/#/flatten'));
+
+flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+You can configure custom toolkit (like [underscorejs](http://underscorejs.org/)), and use it throughout your application
+
+```javascript
+var util = {};
+util.partial = call.bind(require('es5-ext/function/#/partial'));
+util.flatten = call.bind(require('es5-ext/array/#/flatten'));
+util.startsWith = call.bind(require('es5-ext/string/#/starts-with'));
+
+util.flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+As with native ones most methods are generic and can be run on any type of object.

+# es6-iterator
+## ECMAScript 6 Iterator interface
+
+### Installation
+
+	$ npm install es6-iterator
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.
+

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)

+### Esrecurse [![Build Status](https://secure.travis-ci.org/estools/esrecurse.png)](http://travis-ci.org/estools/esrecurse)
+
+Esrecurse ([esrecurse](http://github.com/estools/esrecurse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+recursive traversing functionality.
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+esrecurse.visit(ast, {
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+```
+
+We can use `Visitor` instance.
+
+```javascript
+var visitor = new esrecurse.Visitor({
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+
+visitor.visit(ast);
+```
+
+We can inherit `Visitor` instance easily.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    this.visit(node.left);
+    // do something...
+    this.visit(node.right);
+};
+```
+
+And you can invoke default visiting operation inside custom visit operation.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    // do something...
+    this.visitChildren(node);
+};
+```

+### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.png)](http://travis-ci.org/estools/estraverse)
+
+Estraverse ([estraverse](http://github.com/estools/estraverse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+traversal functions from [esmangle project](http://github.com/estools/esmangle).
+
+### Documentation
+
+You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node, parent) {
+        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
+            return estraverse.VisitorOption.Skip;
+    },
+    leave: function (node, parent) {
+        if (node.type == 'VariableDeclarator')
+          console.log(node.id.name);
+    }
+});
+```
+
+We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node) {
+        this.break();
+    }
+});
+```
+
+And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
+
+```javascript
+result = estraverse.replace(tree, {
+    enter: function (node) {
+        // Replace it with replaced.
+        if (node.type === 'Literal')
+            return replaced;
+    }
+});
+```
+
+By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Extending the exising traversing rules.
+    keys: {
+        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+        TestExpression: ['argument']
+    }
+});
+```
+
+By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Iterating the child **nodes** of unknown nodes.
+    fallback: 'iteration'
+});
+```

+# Espree
+
+Espree is an actively-maintained fork Esprima, a high performance,
+standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+parser written in ECMAScript (also popularly known as
+[JavaScript](http://en.wikipedia.org/wiki/JavaScript)).
+
+## Features
+
+- Full support for ECMAScript 5.1 ([ECMA-262](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Implements [ESTree](https://github.com/estree/estree) (both ES5 and ES6 specs) as the AST format.
+- Optional tracking of syntax node location (index-based and line-column)
+- Heavily tested and battle-hardened by inclusion in [ESLint](http://eslint.org)
+
+## Usage
+
+Install:
+
+```
+npm i espree --save
+```
+
+And in your Node.js code:
+
+```javascript
+var espree = require("espree");
+
+var ast = espree.parse(code);
+```
+
+There is a second argument to `parse()` that allows you to specify various options:
+
+```javascript
+var espree = require("espree");
+
+var ast = espree.parse(code, {
+
+    // attach range information to each node
+    range: true,
+
+    // attach line/column location information to each node
+    loc: true,
+
+    // create a top-level comments array containing all comments
+    comments: true,
+
+    // attach comments to the closest relevant node as leadingComments and
+    // trailingComments
+    attachComment: true,
+
+    // create a top-level tokens array containing all tokens
+    tokens: true,
+
+    // try to continue parsing if an error is encountered, store errors in a
+    // top-level errors array
+    tolerant: true,
+
+    // specify parsing features (default only has blockBindings: true)

+        objectLiteralShorthandProperties: true,
+

+        objectLiteralDuplicateProperties: true,
+
+        // enable parsing of generators/yield
+        generators: true,
+
+        // enable parsing spread operator
+        spread: true,
+
+        // enable parsing classes
+        classes: true,
+

+        jsx: true,

+
+## Plans
+
+Espree starts as a fork of Esprima v1.2.2, the last stable published released of Esprima before work on ECMAScript 6 began. Espree's first version is therefore v1.2.2 and is 100% compatible with Esprima v1.2.2 as a drop-in replacement. The version number will be incremented based on [semantic versioning](http://semver.org/) as features and bug fixes are added.
+
+The immediate plans are:
+
+1. Move away from giant files and move towards small, modular files that are easier to manage.
+1. Move towards CommonJS for all files and use browserify to create browser bundles.
+1. Support ECMAScript version filtering, allowing users to specify which version the parser should work in (similar to Acorn's `ecmaVersion` property).
+1. Add tests to track comment attachment.
+1. Add well-thought-out features that are useful for tools developers.
+1. Add full support for ECMAScript 6.
+1. Add optional parsing of JSX.
+
+## Esprima Compatibility Going Forward
+
+The primary goal is to produce the exact same AST structure as Esprima and Acorn, and that takes precedence over anything else. (The AST structure being the ESTree API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same.
+
+Espree may also deviate from Esprima in the interface it exposes.
+
+## Frequent and Incremental Releases
+
+Espree will not do giant releases. Releases will happen periodically as changes are made and incremental releases will be made towards larger goals. For instance, we will not have one big release for ECMAScript 6 support. Instead, we will implement ECMAScript 6, piece-by-piece, hiding those pieces behind an `ecmaFeatures` property that allows you to opt-in to use those features.
+
+## Contributing
+
+Issues and pull requests will be triaged and responded to as quickly as possible. We operate under the [ESLint Contributor Guidelines](http://eslint.org/docs/developer-guide/contributing.html), so please be sure to read them before contributing.

+## Build Commands
+
+* `npm test` - run all linting and tests
+* `npm run lint` - run all linting
+* `npm run browserify` - creates a version of Espree that is usable in a browser
+
+## Known Incompatibilities
+
+In an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change.
+
+### Esprima 1.2.2
+
+* None.
+
+### Esprima/Harmony Branch
+
+* Esprima/Harmony uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2.
+* Espree uses ESTree format for the AST nodes whereas Esprima/Harmony uses a nonstandard format.
+
+### Esprima-FB
+
+* All Esprima/Harmony incompatibilities.
+
+## Frequently Asked Questions
+
+### Why are you forking Esprima?
+
+[ESLint](http://eslint.org) has been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development has increased dramatically and Esprima has fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that has caused our users frustration.
+
+We decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API.
+
+### Have you tried working with Esprima?
+
+Yes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima. Unfortunately, we've been unable to make much progress towards getting our needs addressed.
+
+We are actively working with Esprima as part of its adoption by the jQuery Foundation. We are hoping to reconcile Espree with Esprima at some point in the future, but there are some different philosophies around how the projects work that need to be worked through. We're committed to a goal of merging Espree back into Esprima, or at the very least, to have Espree track Esprima as an upstream target so there's no duplication of effort. In the meantime, we will continue to update and maintain Espree.
+
+### Why don't you just use Facebook's Esprima fork?
+
+`esprima-fb` is Facebook's Esprima fork that features JSX and Flow type annotations. We tried working with `esprima-fb` in our evaluation of how to support ECMAScript 6 and JSX in ESLint. Unfortunately, we were hampered by bugs that were part of Esprima (not necessarily Facebook's code). Since `esprima-fb` tracks the Esprima Harmony branch, that means we still were unable to get fixes or features we needed in a timely manner.
+
+### Why don't you just use Acorn?
+
+Acorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint.
+
+We expect there are other tools like ESLint that rely on more than just the AST produced by Esprima, and so a drop-in replacement will help those projects as well as ESLint.
+
+### What ECMAScript 6 features do you support?
+
+All of them.
+
+### Why use Espree instead of Esprima?
+
+* Faster turnaround time on bug fixes
+* More frequent releases
+* Better communication and responsiveness to issues
+* Ongoing development
+
+### Why use Espree instead of Esprima-FB?
+
+* Opt-in to just the ECMAScript 6 features you want
+* JSX support is off by default, so you're not forced to use it to use ECMAScript 6
+* Stricter ECMAScript 6 support

+estraverse-fb
+=============
+[![Build Status](https://travis-ci.org/RReverser/estraverse-fb.svg?branch=master)](https://travis-ci.org/RReverser/estraverse-fb)
+
+Drop-in for estraverse that enables traversal over React's JSX and Flow nodes using monkey-patching technique.
+
+You can use estraverse-fb in two possible ways:
+
+* by default, you just require it and it injects needed keys into your installed version of estraverse (it's installed automatically if you don't have it yet):
+    ```javascript
+    var estraverse = require('estraverse-fb');
+    /* same as:
+        require('estraverse-fb');
+        var estraverse = require('estraverse');
+    */
+
+    estraverse.traverse(ast, {
+        enter: ...,
+        leave: ...
+    });
+    ```
+
+* alternatively, you can use it manually for selected traversals:
+    ```javascript
+    var jsxKeys = require('estraverse-fb/keys');
+
+    estraverse.traverse(ast, {
+        enter: ...,
+        leave: ...,
+        keys: jsxKeys
+    })
+```
+
+Check out [estraverse page](https://github.com/Constellation/estraverse) for detailed usage.

+### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.png)](http://travis-ci.org/estools/estraverse)
+
+Estraverse ([estraverse](http://github.com/estools/estraverse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+traversal functions from [esmangle project](http://github.com/estools/esmangle).
+
+### Documentation
+
+You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node, parent) {
+        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
+            return estraverse.VisitorOption.Skip;
+    },
+    leave: function (node, parent) {
+        if (node.type == 'VariableDeclarator')
+          console.log(node.id.name);
+    }
+});
+```
+
+We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node) {
+        this.break();
+    }
+});
+```
+
+And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
+
+```javascript
+result = estraverse.replace(tree, {
+    enter: function (node) {
+        // Replace it with replaced.
+        if (node.type === 'Literal')
+            return replaced;
+    }
+});
+```
+
+By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Extending the exising traversing rules.
+    keys: {
+        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+        TestExpression: ['argument']
+    }
+});
+```
+
+By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Iterating the child **nodes** of unknown nodes.
+    fallback: 'iteration'
+});
+```

+# globals [![Build Status](https://travis-ci.org/sindresorhus/globals.svg?branch=master)](https://travis-ci.org/sindresorhus/globals)
+
+> Global identifiers from different JavaScript environments
+
+Extracted from [JSHint](https://github.com/jshint/jshint/blob/master/src/vars.js) and [ESLint](https://github.com/nzakas/eslint/blob/master/conf/environments.json) and merged.
+
+It's just a [JSON file](globals.json), so use it in whatever environment you like.
+
+
+## Install
+
+```
+$ npm install --save globals
+```
+
+
+## Usage
+
+```js
+var globals = require('globals');
+
+console.log(globals.browser);
+/*
+{
+	addEventListener: false,
+	applicationCache: false,
+	ArrayBuffer: false,
+	atob: false,
+	...
+}
+*/
+```
+
+Each global is given a value of `true` or `false`. A value of `true` indicates that the variable may be overwritten. A value of `false` indicates that the variable should be considered read-only. This information is used by static analysis tools to flag incorrect behavior. We assume all variables should be `false` unless we hear otherwise.

+JS-YAML - YAML 1.2 parser and serializer for JavaScript
+=======================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+[Online Demo](http://nodeca.github.com/js-yaml/)
+
+
+This is an implementation of [YAML](http://yaml.org/), a human friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+
+
+
+
+```
+
+Browser support was done mostly for online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resourses to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+yaml = require('js-yaml');
+fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  var doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns a JavaScript
+object or throws `YAMLException` on error. By default, does not support regexps,
+functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will throw on warnings if this function is not provided.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, JSON schema is not as strict as defined in the YAML specification.
+It allows numbers in any notaion, use `Null` and `NULL` as `null`, etc.
+Core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources you
+must additionally validate object structure, to avoid injections:
+
+``` javascript
+var untrusted_code = '"toString": ! "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string, iterator [ , options ])
+
+Same as `safeLoad()`, but understands multi-document sources and apply
+`iterator` to each document.
+
+``` javascript
+var yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string, iterator [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw exception if you try to dump regexps or functions. However, you can
+disable exceptions by `skipInvalid` option.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+
+styles:
+
+``` none
+!!null
+  "canonical"   => "~"
+
+!!int
+  "binary"      => "0b1", "0b101010", "0b1110001111010"
+  "octal"       => "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" => "0x1", "0x2A", "0x1C7A"
+
+!!null, !!bool, !!float
+  "lowercase"   => "null", "true", "false", ".nan", '.inf'
+  "uppercase"   => "NULL", "TRUE", "FALSE", ".NAN", '.INF'
+  "camelcase"   => "Null", "True", "False", ".NaN", '.Inf'
+```
+
+By default, !!int uses `decimal`, and !!null, !!bool, !!float use `lowercase`.
+
+
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS do not allows objects
+or array as keys, and stringifies (by calling .toString method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```
+
+
+Breaking changes in 2.x.x -> 3.x.x
+----------------------------------
+
+If your have not used __custom__ tags or loader classes and not loaded yaml
+files via `require()` - no changes needed. Just upgrade library.
+
+In other case, you should:
+
+1. Replace all occurences of `require('xxxx.yml')` by `fs.readFileSync()` +
+  `yaml.safeLoad()`.
+2. rewrite your custom tags constructors and custom loader
+  classes, to conform new API. See
+  [examples](https://github.com/nodeca/js-yaml/tree/master/examples) and
+  [wiki](https://github.com/nodeca/js-yaml/wiki) for details.

+argparse
+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.png?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4
+{ foo: '3', bar: '4' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({paramters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supportied yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument([names or flags], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flags``` - Either a name or a list of option strings, e.g. foo or -f, --foo.
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.

+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.

+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+ * of Action instances.
+ *
+ * #####Alowed keywords:

+ * - `storeTrue`
+ * - `storeFalse`
+ * - `append`
+ * - `appendConstant`
+ * - `count`

+ * new Action(options)
+ *
+ * Base class for all actions. Used only for inherits
+ *
+ *
+ * ##### Options:
+ *
+ * - `optionStrings`  A list of command-line option strings for the action.
+ * - `dest`  Attribute to hold the created object(s)
+ * - `nargs`  The number of command-line arguments that should be consumed.
+ * By default, one argument will be consumed and a single value will be
+ * produced.
+ * - `constant`  Default value for an action with no value.
+ * - `defaultValue`  The value to be produced if the option is not specified.
+ * - `type`  Cast to 'string'|'int'|'float'|'complex'|function (string). If
+ * None, 'string'.
+ * - `choices`  The choices available.
+ * - `required`  True if the action must always be specified at the command
+ * line.
+ * - `help`  The help describing the argument.
+ * - `metavar`  The name to be used for the option's argument with the help
+ * string. If None, the 'dest' value will be used as the name.
+ *
+ * ##### nargs supported values:
+ *
+ * - `N` (an integer) consumes N arguments (and produces a list)
+ * - `?`  consumes zero or one arguments
+ * - `*` consumes zero or more arguments (and produces a list)
+ * - `+` consumes one or more arguments (and produces a list)
+ *
+ * Note: that the difference between the default and nargs=1 is that with the
+ * default, a single value will be produced, while with nargs=1, a list
+ * containing a single value will be produced.

+# lodash v3.8.0
+
+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/3.8.0-npm) for more details.
+
+**Note:**

+Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.

+Install [n_](https://www.npmjs.com/package/n_) for a REPL that includes lodash by default.
+
+## Module formats
+
+lodash is also available in a variety of other builds & module formats.
+
+ * npm packages for [modern](https://www.npmjs.com/package/lodash), [compatibility](https://www.npmjs.com/package/lodash-compat), & [per method](https://www.npmjs.com/browse/keyword/lodash-modularized) builds
+ * AMD modules for [modern](https://github.com/lodash/lodash/tree/3.8.0-amd) & [compatibility](https://github.com/lodash/lodash-compat/tree/3.8.0-amd) builds

+ * 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`,

+**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
+standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+parser written in ECMAScript (also popularly known as
+[JavaScript](https://en.wikipedia.org/wiki/JavaScript).
+Esprima is created and maintained by [Ariya Hidayat](https://twitter.com/ariyahidayat),
+with the help of [many contributors](https://github.com/jquery/esprima/contributors).
+
+### Features
+
+- Full support for ECMAScript 5.1 ([ECMA-262](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Sensible [syntax tree format](https://github.com/estree/estree/blob/master/spec.md) as standardized by [EStree project](https://github.com/estree/estree)
+- Optional tracking of syntax node location (index-based and line-column)
+- Heavily tested (~1000 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://travis-ci.org/jquery/esprima))
+- [Partial support](https://github.com/jquery/esprima/issues/1099) for ECMAScript 6
+
+Esprima serves as a **building block** for some JavaScript
+language tools, from [code instrumentation](http://esprima.org/demo/functiontrace.html)
+to [editor autocompletion](http://esprima.org/demo/autocomplete.html).
+
+Esprima runs on many popular web browsers, as well as other ECMAScript platforms such as
+[Rhino](http://www.mozilla.org/rhino), [Nashorn](http://openjdk.java.net/projects/nashorn/), and [Node.js](https://npmjs.org/package/esprima).
+
+For more information, check the web site [esprima.org](http://esprima.org).

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.png)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instanting the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+## Functions
+
+The top-level exported function has a `cache` property, which is an LRU
+cache set to store 100 items.  So, calling these methods repeatedly
+with the same pattern and options will use the same Minimatch object,
+saving the cost of parsing it multiple times.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+# brace-expansion
+
+[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html), 
+as known from sh/bash, in JavaScript.
+
+[![build status](https://secure.travis-ci.org/juliangruber/brace-expansion.svg)](http://travis-ci.org/juliangruber/brace-expansion)
+
+[![testling badge](https://ci.testling.com/juliangruber/brace-expansion.png)](https://ci.testling.com/juliangruber/brace-expansion)
+
+## Example
+
+```js
+var expand = require('brace-expansion');
+
+expand('file-{a,b,c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('-v{,,}')
+// => ['-v', '-v', '-v']
+
+expand('file{0..2}.jpg')
+// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
+
+expand('file-{a..c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('file{2..0}.jpg')
+// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
+
+expand('file{0..4..2}.jpg')
+// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
+
+expand('file-{a..e..2}.jpg')
+// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
+
+expand('file{00..10..5}.jpg')
+// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
+
+expand('{{A..C},{a..c}}')
+// => ['A', 'B', 'C', 'a', 'b', 'c']
+
+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma seperated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install brace-expansion
+```

+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `` and ``.
+
+[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
+[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
+
+[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']`.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install balanced-match
+```

+methods
+=======
+
+``` js
+var concatMap = require('concat-map')
+```
+
+concatMap(xs, fn)
+-----------------
+
+Return an array of concatenated elements by calling `fn(x, i)` for each element
+`x` and each index `i` in the array `xs`.
+
+When `fn(x, i)` returns an array, its result will be concatenated with the
+result array. If `fn(x, i)` returns anything else, that value will be pushed
+onto the end of the result array.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# 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 string or array of strings to always treat as booleans
+* `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
+
+# install
+
+With [npm](https://npmjs.org) do:

+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal

+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.

+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal
+               permission string.
+
+```
+
+# install
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install mkdirp
+```
+
+to get the library, or
+
+```
+npm install -g mkdirp
+```
+
+to get the command.

+# Optionator
+
+
+Optionator is an option parsing and help generation library.
+
+## Why?
+The  problem with other option parsers, such as `yargs` or `minimist`, is they just accept all input, valid or not.
+With Optionator, if you mistype an option, it will give you an error (with a suggestion for what you meant).
+If you give the wrong type of argument for an option, it will give you an error rather than supplying the wrong input to your application.
+
+    $ cmd --halp
+    Invalid option '--halp' - perhaps you meant '--help'?
+
+    $ cmd --count str
+    Invalid value for option 'count' - expected type Int, received value: str.
+
+Over helpful features include reformatting the help text based on the size of the console, so that it fits even if the console is narrow, and accepting not just an array (eg. process.argv), but a string or object as well, making things like testing much easier.
+
+## About
+Optionator uses [type-check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) behind the scenes to cast and verify input according the specified types.
+
+Optionator is used by [Grasp](http://graspjs.com), [eslint](http://eslint.org), [LiveScript](http://livescript.net), [esmangle](https://github.com/estools/esmangle), [escodegen](https://github.com/estools/escodegen), and more.
+
+MIT license. Version 0.5.0
+
+    npm install optionator

+
+## Usage
+`require('optionator');` returns a function. It has one property, `VERSION`, the current version of the library as a string. This function is called with an object specifying your options and other information, see the [settings format section](#settings-format). This in turn returns an object with three properties, `parse`, `generateHelp`, and `generateHelpForOption`, which are all functions.
+
+```js
+var optionator = require('optionator')({
+  prepend: 'Usage: cmd [options]',
+  append: 'Version 1.0.0',
+  options: [{
+    option: 'help',
+    alias: 'h',
+    type: 'Boolean',
+    description: 'displays help'
+  }, {
+    option: 'count',
+    alias: 'c',
+    type: 'Int',
+    description: 'number of things',
+    example: 'cmd --count 2'
+  }]
+});
+```
+
+### parse(input, parseOptions)
+`parse` processes the `input` according to your settings, and returns an object with the results.
+
+##### arguments
+* input - `[String] | Object | String` - the input you wish to parse
+* parseOptions - `{slice: Int}` - all options optional
+    - `slice` specifies how much to slice away from the beginning if the input is an array or string - by default `0` for string, `2` for array (works with `process.argv`)
+
+##### returns
+`Object` - the parsed options, each key is a camelCase version of the option name (specified in dash-case), and each value is the processed value for that option. Positional values are in an array under the `_` key.
+
+##### example
+```js
+parse(['node', 't.js', '--count', '2', 'positional']); // {count: 2, _: ['positional']}
+parse('--count 2 positional');                         // {count: 2, _: ['positional']}
+parse({count: 2, _:['positional']});                   // {count: 2, _: ['positional']}
+```
+
+### generateHelp(helpOptions)
+`generateHelp` produces help text based on your settings.
+
+##### arguments
+* helpOptions - `{showHidden: Boolean, interpolate: Object}` - all options optional
+    - `showHidden` specifies whether to show options with `hidden: true` specified, by default it is `false`
+    - `interpolate` specify data to be interpolated in `prepend` and `append` text, `{{key}}` is the format - eg. `generateHelp({interpolate:{version: '0.4.2'}})`, will change this `append` text: `Version {{version}}` to `Version 0.4.2`
+
+##### returns
+`String` - the generated help text
+
+##### example
+```js
+generateHelp(); /*
+"Usage: cmd [options] positional
+
+  -h, --help       displays help
+  -c, --count Int  number of things
+
+Version  1.0.0
+"*/
+```
+
+### generateHelpForOption(optionName)
+`generateHelpForOption` produces expanded help text for the specified with `optionName` option. If an `example` was specified for the option, it will be displayed,  and if a `longDescription` was specified, it will display that instead of the `description`.
+
+##### arguments
+* optionName - `String` - the name of the option to display
+
+##### returns
+`String` - the generated help text for the option
+
+##### example
+```js
+generateHelpForOption('count'); /*
+"-c, --count Int
+description: number of things
+example: cmd --count 2
+"*/
+```
+
+## Settings Format
+When your `require('optionator')`, you get a function that takes in a settings object. This object has the type:
+
+    {
+      prepend: Maybe String,
+      append: Maybe String,
+      options: [{heading: String} | {
+        option: String,
+        alias: Maybe [String] | String,
+        type: Maybe String,
+        enum: Maybe [String],
+        default: Maybe String,
+        restPositional: Maybe Boolean,
+        requried: Maybe Boolean,
+        overrideRequired: Maybe Bookean,
+        dependsOn: Maybe [String] | String,
+        description: Maybe String,
+        longDescription: Maybe String,
+        example: Maybe [String] | String
+      }],
+      helpStyle: Maybe {
+        aliasSeparator: Maybe String,
+        typeSeparator: Maybe String,
+        descriptionSeparator: Maybe String,
+        initialIndent: Maybe Int,
+        secondaryIndent: Maybe Int,
+        maxPadFactor: Maybe Number
+      },
+      mutuallyExclusive: Maybe [[String | [String]]],
+      concatRepeatedArrays: Maybe Boolean,
+      mergeRepeatedObjects: Maybe Boolean
+    }
+
+### Top Level Properties
+* `prepend` is an optional string to be placed before the options in the help text
+* `append` is an optional string to be placed after the options in the help text
+* `options` is a required array specifying your options and headings, the options and headings will be displayed in the order specified
+* `helpStyle` is an optional object which enables you to change the default appearance of some aspects of the help text
+* `mutuallyExclusive` is an optional array of arrays of either strings or arrays of strings. The top level array is a list of rules, each rule is a list of elements - each element can be either a string (the name of an option), or a list of strings (a group of option names) - there will be an error if more than one element is present
+* `concatRepeatedArrays` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an array value and is repeated, the subsequent values for the flag will be appended rather than overwriting the original value - eg. option `g` of type `[String]`: `-g a -g b -g c,d` will result in `['a','b','c','d']`
+* `mergeRepeatedObjects` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an object value and is repeated, the subsequent values for the flag will be merged rather than overwriting the original value - eg. option `g` of type `Object`: `-g a:1 -g b:2 -g c:3,d:4` will result in `{a: 1, b: 2, c: 3, d: 4}`
+
+#### Heading Properties
+* `heading` a required string, the name of the heading
+
+#### Option Properties
+* `option` the required name of the option - use dash-case, without the leading dashes
+* `alias` is an optional string or array of strings which specify any aliases for the option
+* `type` is a required string in the [type check](https://github.com/gkz/type-check) [format](https://github.com/gkz/type-check#type-format), this will be used to cast the inputted value and validate it
+* `enum` is an optional array of strings, each string will be parsed by [levn](https://github.com/gkz/levn) - the argument value must be one of the resulting values - each potential value must validate against the specified `type`
+* `default` is a optional string, which will be parsed by [levn](https://github.com/gkz/levn) and used as the default value if none is set - the value must validate against the specified `type`
+* `restPositional` is an optional boolean - if set to `true`, everything after the option will be taken to be a positional argument, even if it looks like a named argument
+* `required` is an optional boolean - if set to `true`, the option parsing will fail if the option is not defined
+* `overrideRequired` is a optional boolean - if set to `true` and the option is used, and there is another option which is required but not set, it will override the need for the required option and there will be no error - this is useful if you have required options and want to use `--help` or `--version` flags
+* `dependsOn` is an optional string or array of strings - if simply a string (the name of another option), it will make sure that that other option is set, if an array of strings, depending on whether `'and'` or `'or'` is first, it will either check whether all (`['and', 'option-a', 'option-b']`), or at least one (`['or', 'option-a', 'option-b']`) other options are set
+* `description` is an optional string, which will be displayed next to the option in the help text
+* `longDescription` is an optional string, it will be displayed instead of the `description` when `generateHelpForOption` is used
+* `example` is an optional string or array of strings with example(s) for the option - these will be displayed when `generateHelpForOption` is used
+
+#### Help Style Properties
+* `aliasSeparator` is an optional string, separates multiple names from each other - default: ' ,'
+* `typeSeparator` is an optional string, separates the type from the names - default: ' '
+* `descriptionSeparator` is an optional string , separates the description from the padded name and type - default: '  '
+* `initialIndent` is an optional int - the amount of indent for options - default: 2
+* `secondaryIndent` is an optional int - the amount of indent if wrapped fully (in addition to the initial indent) - default: 4
+* `maxPadFactor` is an optional number - affects the default level of padding for the names/type, it is multiplied by the average of the length of the names/type - default: 1.5
+
+## Argument Format
+At the highest level there are two types of arguments: named, and positional.
+
+Name arguments of any length are prefixed with `--` (eg. `--go`), and those of one character may be prefixed with either `--` or `-` (eg. `-g`).
+
+There are two types of named arguments: boolean flags (eg. `--problemo`, `-p`) which take no value and result in a `true` if they are present, the falsey `undefined` if they are not present, or `false` if present and explicitly prefixed with `no` (eg. `--no-problemo`). Named arguments with values (eg. `--tseries 800`, `-t 800`) are the other type. If the option has a type `Boolean` it will automatically be made into a boolean flag. Any other type results in a named argument that takes a value.
+
+For more information about how to properly set types to get the value you want, take a look at the [type check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) pages.
+
+You can group single character arguments that use a single `-`, however all except the last must be boolean flags (which take no value). The last may be a boolean flag, or an argument which takes a value - eg. `-ba 2` is equivalent to `-b -a 2`.
+
+Positional arguments are all those values which do not fall under the above - they can be anywhere, not just at the end. For example, in `cmd -b one -a 2 two` where `b` is a boolean flag, and `a` has the type `Number`, there are two positional arguments, `one` and `two`.
+
+Everything after an `--` is positional, even if it looks like a named argument.
+
+You may optionally use `=` to separate option names from values, for example: `--count=2`.
+
+If you specify the option `NUM`, then any argument using a single `-` followed by a number will be valid and will set the value of `NUM`. Eg. `-2` will be parsed into `NUM: 2`.
+
+If duplicate named arguments are present, the last one will be taken.
+
+## Technical About
+`optionator` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [levn](https://github.com/gkz/levn) to cast arguments to their specified type, and uses [type-check](https://github.com/gkz/type-check) to validate values. It also uses the [prelude.ls](http://preludels.com/) library.

+deep-is
+==========
+
+Node's `assert.deepEqual() algorithm` as a standalone module. Exactly like
+[deep-equal](https://github.com/substack/node-deep-equal) except for the fact that `deepEqual(NaN, NaN) === true`.
+
+This module is around [5 times faster](https://gist.github.com/2790507)
+than wrapping `assert.deepEqual()` in a `try/catch`.
+
+[![browser support](http://ci.testling.com/thlorenz/deep-is.png)](http://ci.testling.com/thlorenz/deep-is)
+
+[![build status](https://secure.travis-ci.org/thlorenz/deep-is.png)](http://travis-ci.org/thlorenz/deep-is)
+
+example
+=======
+
+``` js
+var equal = require('deep-is');

+        { a : [ 2, 3 ], b : [ 4 ] },
+        { a : [ 2, 3 ], b : [ 4 ] }

+    )
+]);
+```
+
+methods
+=======
+
+var deepIs = require('deep-is')
+
+deepIs(a, b)
+---------------
+
+Compare objects `a` and `b`, returning whether they are equal according to a

+# fast-levenshtein - Levenshtein algorithm in Javascript
+
+[![Build Status](https://secure.travis-ci.org/hiddentao/fast-levenshtein.png)](http://travis-ci.org/hiddentao/fast-levenshtein)
+
+An efficient Javascript implementation of the [Levenshtein algorithm](http://en.wikipedia.org/wiki/Levenshtein_distance) with asynchronous callback support.
+
+## Features
+
+* Works in node.js and in the browser.
+* Better performance than other implementations by not needing to store the whole matrix ([more info](http://www.codeproject.com/Articles/13525/Fast-memory-efficient-Levenshtein-algorithm)).
+* Provides synchronous and asynchronous versions of the algorithm.
+* Asynchronous version is almost as fast as the synchronous version for small strings and can also provide progress updates.
+* Comprehensive test suite and performance benchmark.
+* Small: <1 KB minified and gzipped
+
+## Installation
+
+### node.js
+
+Install using [npm](http://npmjs.org/):
+
+```bash
+$ npm install fast-levenshtein
+```
+
+### Browser
+
+Using bower:
+
+```bash
+$ bower install fast-levenshtein
+```
+
+If you are not using any module loader system then the API will then be accessible via the `window.Levenshtein` object.
+
+## Examples
+
+**Synchronous**
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+var distance = levenshtein.get('back', 'book');   // 2
+var distance = levenshtein.get('我愛你', '我叫你');   // 1
+```
+
+**Asynchronous**
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+levenshtein.getAsync('back', 'book', function (err, distance) {
+  // err is null unless an error was thrown
+  // distance equals 2
+});
+```
+
+**Asynchronous with progress updates**
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+var hugeText1 = fs.readFileSync(...);
+var hugeText2 = fs.readFileSync(...);
+
+levenshtein.getAsync(hugeText1, hugeText2, function (err, distance) {
+  // process the results as normal
+}, {
+  progress: function(percentComplete) {
+    console.log(percentComplete + ' % completed so far...');
+  }
+);
+```
+
+## Building and Testing
+
+To build the code and run the tests:
+
+```bash
+$ npm install -g grunt-cli
+$ npm install
+$ npm run build
+```
+
+## Performance
+
+_Thanks to [Titus Wormer](https://github.com/wooorm) for [encouraging me](https://github.com/hiddentao/fast-levenshtein/issues/1) to do this._
+
+Benchmarked against other node.js levenshtein distance modules (on Macbook Air 2012, Core i7, 8GB RAM):
+
+```bash
+Running suite Implementation comparison [benchmark/speed.js]...
+>> levenshtein-edit-distance x 234 ops/sec ±3.02% (73 runs sampled)
+>> levenshtein-component x 422 ops/sec ±4.38% (83 runs sampled)
+>> levenshtein-deltas x 283 ops/sec ±3.83% (78 runs sampled)
+>> natural x 255 ops/sec ±0.76% (88 runs sampled)
+>> levenshtein x 180 ops/sec ±3.55% (86 runs sampled)
+>> fast-levenshtein x 1,792 ops/sec ±2.72% (95 runs sampled)
+Benchmark done.
+Fastest test is fast-levenshtein at 4.2x faster than levenshtein-component
+```
+
+You can run this benchmark yourself by doing:
+
+```bash
+$ npm install -g grunt-cli
+$ npm install
+$ npm run build
+$ npm run benchmark
+```
+
+## Contributing

+# levn [![Build Status](https://travis-ci.org/gkz/levn.png)](https://travis-ci.org/gkz/levn) 
+__Light ECMAScript (JavaScript) Value Notation__
+Levn is a library which allows you to parse a string into a JavaScript value based on an expected type. It is meant for short amounts of human entered data (eg. config files, command line arguments).
+
+Levn aims to concisely describe JavaScript values in text, and allow for the extraction and validation of those values. Levn uses [type-check](https://github.com/gkz/type-check) for its type format, and to validate the results. MIT license. Version 0.2.5.
+
+__How is this different than JSON?__ levn is meant to be written by humans only, is (due to the previous point) much more concise, can be validated against supplied types, has regex and date literals, and can easily be extended with custom types. On the other hand, it is probably slower and thus less efficient at transporting large amounts of data, which is fine since this is not its purpose.
+
+    npm install levn
+
+For updates on levn, [follow me on twitter](https://twitter.com/gkzahariev).
+
+
+## Quick Examples
+
+```js
+var parse = require('levn').parse;
+parse('Number', '2');      // 2
+parse('String', '2');      // '2'
+parse('String', 'levn');   // 'levn'
+parse('String', 'a b');    // 'a b'
+parse('Boolean', 'true');  // true
+
+parse('Date', '#2011-11-11#'); // (Date object)
+parse('Date', '2011-11-11');   // (Date object)
+parse('RegExp', '/[a-z]/gi');  // /[a-z]/gi
+parse('RegExp', 're');         // /re/
+
+parse('Number | String', 'str'); // 'str'
+parse('Number | String', '2');   // 2
+
+parse('[Number]', '[1,2,3]');                      // [1,2,3]
+parse('(String, Boolean)', '(hi, false)');         // ['hi', false]
+parse('{a: String, b: Number}', '{a: str, b: 2}'); // {a: 'str', b: 2}
+
+// at the top level, you can ommit surrounding delimiters
+parse('[Number]', '1,2,3');                      // [1,2,3]
+parse('(String, Boolean)', 'hi, false');         // ['hi', false]
+parse('{a: String, b: Number}', 'a: str, b: 2'); // {a: 'str', b: 2}
+
+// wildcard - auto choose type
+parse('*', '[hi,(null,[42]),{k: true}]'); // ['hi', [null, [42]], {k: true}]
+```
+## Usage
+
+`require('levn');` returns an object that exposes three properties. `VERSION` is the current version of the library as a string. `parse` and `parsedTypeParse` are functions.
+
+```js
+// parse(type, input, options);
+parse('[Number]', '1,2,3'); // [1, 2, 3]
+
+// parsedTypeParse(parsedType, input, options);
+var parsedType = require('type-check').parseType('[Number]');
+parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
+```
+
+### parse(type, input, options)
+
+`parse` casts the string `input` into a JavaScript value according to the specified `type` in the [type format](https://github.com/gkz/type-check#type-format) (and taking account the optional `options`) and returns the resulting JavaScript value.
+
+##### arguments
+* type - `String` - the type written in the [type format](https://github.com/gkz/type-check#type-format) which to check against
+* input - `String` - the value written in the [levn format](#levn-format)
+* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
+
+##### returns
+`*` - the resulting JavaScript value
+
+##### example
+```js
+parse('[Number]', '1,2,3'); // [1, 2, 3]
+```
+
+### parsedTypeParse(parsedType, input, options)
+
+`parsedTypeParse` casts the string `input` into a JavaScript value according to the specified `type` which has already been parsed (and taking account the optional `options`) and returns the resulting JavaScript value. You can parse a type using the [type-check](https://github.com/gkz/type-check) library's `parseType` function.
+
+##### arguments
+* type - `Object` - the type in the parsed type format which to check against
+* input - `String` - the value written in the [levn format](#levn-format)
+* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
+
+##### returns
+`*` - the resulting JavaScript value
+
+##### example
+```js
+var parsedType = require('type-check').parseType('[Number]');
+parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
+```
+
+## Levn Format
+
+Levn can use the type information you provide to choose the appropriate value to produce from the input. For the same input, it will choose a different output value depending on the type provided. For example, `parse('Number', '2')` will produce the number `2`, but `parse('String', '2')` will produce the string `"2"`.
+
+If you do not provide type information, and simply use `*`, levn will parse the input according the unambiguous "explicit" mode, which we will now detail - you can also set the `explicit` option to true manually in the [options](#options).
+
+* `"string"`, `'string'` are parsed as a String, eg. `"a msg"` is `"a msg"`
+* `#date#` is parsed as a Date, eg. `#2011-11-11#` is `new Date('2011-11-11')`
+* `/regexp/flags` is parsed as a RegExp, eg. `/re/gi` is `/re/gi`
+* `undefined`, `null`, `NaN`, `true`, and `false` are all their JavaScript equivalents
+* `[element1, element2, etc]` is an Array, and the casting procedure is recursively applied to each element. Eg. `[1,2,3]` is `[1,2,3]`.
+* `(element1, element2, etc)` is an tuple, and the casting procedure is recursively applied to each element. Eg. `(1, a)` is `(1, a)` (is `[1, 'a']`).
+* `{key1: val1, key2: val2, ...}` is an Object, and the casting procedure is recursively applied to each property. Eg. `{a: 1, b: 2}` is `{a: 1, b: 2}`.
+* Any test which does not fall under the above, and which does not contain special characters (`[``]``(``)``{``}``:``,`) is a string, eg. `$12- blah` is `"$12- blah"`.
+
+If you do provide type information, you can make your input more concise as the program already has some information about what it expects. Please see the [type format](https://github.com/gkz/type-check#type-format) section of [type-check](https://github.com/gkz/type-check) for more information about how to specify types. There are some rules about what levn can do with the information:
+
+* If a String is expected, and only a String, all characters of the input (including any special ones) will become part of the output. Eg. `[({})]` is `"[({})]"`, and `"hi"` is `'"hi"'`.
+* If a Date is expected, the surrounding `#` can be omitted from date literals. Eg. `2011-11-11` is `new Date('2011-11-11')`.
+* If a RegExp is expected, no flags need to be specified, and the regex is not using any of the special characters,the opening and closing `/` can be omitted - this will have the affect of setting the source of the regex to the input. Eg. `regex` is `/regex/`.
+* If an Array is expected, and it is the root node (at the top level), the opening `[` and closing `]` can be omitted. Eg. `1,2,3` is `[1,2,3]`.
+* If a tuple is expected, and it is the root node (at the top level), the opening `(` and closing `)` can be omitted. Eg. `1, a` is `(1, a)` (is `[1, 'a']`).
+* If an Object is expected, and it is the root node (at the top level), the opening `{` and closing `}` can be omitted. Eg `a: 1, b: 2` is `{a: 1, b: 2}`.
+
+If you list multiple types (eg. `Number | String`), it will first attempt to cast to the first type and then validate - if the validation fails it will move on to the next type and so forth, left to right. You must be careful as some types will succeed with any input, such as String. Thus put String at the end of your list. In non-explicit mode, Date and RegExp will succeed with a large variety of input - also be careful with these and list them near the end if not last in your list.
+
+Whitespace between special characters and elements is inconsequential.
+
+## Options
+
+Options is an object. It is an optional parameter to the `parse` and `parsedTypeParse` functions.
+
+### Explicit
+
+A `Boolean`. By default it is `false`.
+
+__Example:__
+
+```js
+parse('RegExp', 're', {explicit: false});          // /re/
+parse('RegExp', 're', {explicit: true});           // Error: ... does not type check...
+parse('RegExp | String', 're', {explicit: true});  // 're'
+```
+
+`explicit` sets whether to be in explicit mode or not. Using `*` automatically activates explicit mode. For more information, read the [levn format](#levn-format) section.
+
+### customTypes
+
+An `Object`. Empty `{}` by default.
+
+__Example:__
+
+```js
+var options = {
+  customTypes: {
+    Even: {
+      typeOf: 'Number',
+      validate: function (x) {
+        return x % 2 === 0;
+      },
+      cast: function (x) {
+        return {type: 'Just', value: parseInt(x)};
+      }
+    }
+  }
+}
+parse('Even', '2', options); // 2
+parse('Even', '3', options); // Error: Value: "3" does not type check...
+```
+
+__Another Example:__
+```js
+function Person(name, age){
+  this.name = name;
+  this.age = age;
+}
+var options = {
+  customTypes: {
+    Person: {
+      typeOf: 'Object',
+      validate: function (x) {
+        x instanceof Person;
+      },
+      cast: function (value, options, typesCast) {
+        var name, age;
+        if ({}.toString.call(value).slice(8, -1) !== 'Object') {
+          return {type: 'Nothing'};
+        }
+        name = typesCast(value.name, [{type: 'String'}], options);
+        age = typesCast(value.age, [{type: 'Numger'}], options);
+        return {type: 'Just', value: new Person(name, age)};
+    }
+  }
+}
+parse('Person', '{name: Laura, age: 25}', options); // Person {name: 'Laura', age: 25}
+```
+
+`customTypes` is an object whose keys are the name of the types, and whose values are an object with three properties, `typeOf`, `validate`, and `cast`. For more information about `typeOf` and `validate`, please see the [custom types](https://github.com/gkz/type-check#custom-types) section of type-check.
+
+`cast` is a function which receives three arguments, the value under question, options, and the typesCast function. In `cast`, attempt to cast the value into the specified type. If you are successful, return an object in the format `{type: 'Just', value: CAST-VALUE}`, if you know it won't work, return `{type: 'Nothing'}`.  You can use the `typesCast` function to cast any child values. Remember to pass `options` to it. In your function you can also check for `options.explicit` and act accordingly.
+
+## Technical About
+
+`levn` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [type-check](https://github.com/gkz/type-check) to both parse types and validate values. It also uses the [prelude.ls](http://preludels.com/) library.

+# prelude.ls [![Build Status](https://travis-ci.org/gkz/prelude-ls.png?branch=master)](https://travis-ci.org/gkz/prelude-ls)
+
+is a functionally oriented utility library. It is powerful and flexible. Almost all of its functions are curried. It is written in, and is the recommended base library for, LiveScript.
+
+See **[the prelude.ls site](http://preludels.com)** for examples, a reference, and more.
+
+You can install via npm `npm install prelude-ls`
+
+### Development
+
+`make test` to test
+
+`make build` to build `lib` from `src`
+
+`make build-browser` to build browser versions

+# type-check [![Build Status](https://travis-ci.org/gkz/type-check.png?branch=master)](https://travis-ci.org/gkz/type-check)
+
+
+
+`type-check` is a library which allows you to check the types of JavaScript values at runtime with a Haskell like type syntax. It is great for checking external input, for testing, or even for adding a bit of safety to your internal code. It is a major component of [levn](https://github.com/gkz/levn). MIT license. Version 0.3.1. Check out the [demo](http://gkz.github.io/type-check/).
+
+For updates on `type-check`, [follow me on twitter](https://twitter.com/gkzahariev).
+
+    npm install type-check
+
+## Quick Examples
+
+```js
+// Basic types:
+var typeCheck = require('type-check').typeCheck;
+typeCheck('Number', 1);               // true
+typeCheck('Number', 'str');           // false
+typeCheck('Error', new Error);        // true
+typeCheck('Undefined', undefined);    // true
+
+// Comment
+typeCheck('count::Number', 1);        // true
+
+// One type OR another type:
+typeCheck('Number | String', 2);      // true
+typeCheck('Number | String', 'str');  // true
+
+// Wildcard, matches all types:
+typeCheck('*', 2) // true
+
+// Array, all elements of a single type:
+typeCheck('[Number]', [1, 2, 3]);                // true
+typeCheck('[Number]', [1, 'str', 3]);            // false
+
+// Tuples, or fixed length arrays with elements of different types:
+typeCheck('(String, Number)', ['str', 2]);       // true
+typeCheck('(String, Number)', ['str']);          // false
+typeCheck('(String, Number)', ['str', 2, 5]);    // false
+
+// Object properties:
+typeCheck('{x: Number, y: Boolean}', {x: 2, y: false});             // true
+typeCheck('{x: Number, y: Boolean}',       {x: 2});                 // false
+typeCheck('{x: Number, y: Maybe Boolean}', {x: 2});                 // true
+typeCheck('{x: Number, y: Boolean}',      {x: 2, y: false, z: 3});  // false
+typeCheck('{x: Number, y: Boolean, ...}', {x: 2, y: false, z: 3});  // true
+
+// A particular type AND object properties:
+typeCheck('RegExp{source: String, ...}', /re/i);          // true
+typeCheck('RegExp{source: String, ...}', {source: 're'}); // false
+
+// Custom types:
+var opt = {customTypes:
+  {Even: { typeOf: 'Number', validate: function(x) { return x % 2 === 0; }}}};
+typeCheck('Even', 2, opt); // true
+
+// Nested:
+var type = '{a: (String, [Number], {y: Array, ...}), b: Error{message: String, ...}}'
+typeCheck(type, {a: ['hi', [1, 2, 3], {y: [1, 'ms']}], b: new Error('oh no')}); // true
+```

+
+## Usage
+
+`require('type-check');` returns an object that exposes four properties. `VERSION` is the current version of the library as a string. `typeCheck`, `parseType`, and `parsedTypeCheck` are functions.
+
+```js
+// typeCheck(type, input, options);
+typeCheck('Number', 2);               // true
+
+// parseType(type);
+var parsedType = parseType('Number'); // object
+
+// parsedTypeCheck(parsedType, input, options);
+parsedTypeCheck(parsedType, 2);       // true
+```
+
+### typeCheck(type, input, options)
+
+`typeCheck` checks a JavaScript value `input` against `type` written in the [type format](#type-format) (and taking account the optional `options`) and returns whether the `input` matches the `type`.
+
+##### arguments
+* type - `String` - the type written in the [type format](#type-format) which to check against
+* input - `*` - any JavaScript value, which is to be checked against the type
+* options - `Maybe Object` - an optional parameter specifying additional options, currently the only available option is specifying [custom types](#custom-types)
+
+##### returns
+`Boolean` - whether the input matches the type
+
+##### example
+```js
+typeCheck('Number', 2); // true
+```
+
+### parseType(type)
+
+`parseType` parses string `type` written in the [type format](#type-format) into an object representing the parsed type.
+
+##### arguments
+* type - `String` - the type written in the [type format](#type-format) which to parse
+
+##### returns
+`Object` - an object in the parsed type format representing the parsed type
+
+##### example
+```js
+parseType('Number'); // [{type: 'Number'}]
+```
+### parsedTypeCheck(parsedType, input, options)
+
+`parsedTypeCheck` checks a JavaScript value `input` against parsed `type` in the parsed type format (and taking account the optional `options`) and returns whether the `input` matches the `type`. Use this in conjunction with `parseType` if you are going to use a type more than once.
+
+##### arguments
+* type - `Object` - the type in the parsed type format which to check against
+* input - `*` - any JavaScript value, which is to be checked against the type
+* options - `Maybe Object` - an optional parameter specifying additional options, currently the only available option is specifying [custom types](#custom-types)
+
+##### returns
+`Boolean` - whether the input matches the type
+
+##### example
+```js
+parsedTypeCheck([{type: 'Number'}], 2); // true
+var parsedType = parseType('String');
+parsedTypeCheck(parsedType, 'str');     // true
+```
+
+
+## Type Format
+
+### Syntax
+
+White space is ignored. The root node is a __Types__.
+
+* __Identifier__ = `[\$\w]+` - a group of any lower or upper case letters, numbers, underscores, or dollar signs - eg. `String`
+* __Type__ = an `Identifier`, an `Identifier` followed by a `Structure`, just a `Structure`, or a wildcard `*` - eg. `String`, `Object{x: Number}`, `{x: Number}`, `Array{0: String, 1: Boolean, length: Number}`, `*`
+* __Types__ = optionally a comment (an `Indentifier` followed by a `::`), optionally the identifier `Maybe`, one or more `Type`, separated by `|` - eg. `Number`, `String | Date`, `Maybe Number`, `Maybe Boolean | String`
+* __Structure__ = `Fields`, or a `Tuple`, or an `Array` - eg. `{x: Number}`, `(String, Number)`, `[Date]`
+* __Fields__ = a `{`, followed one or more `Field` separated by a comma `,` (trailing comma `,` is permitted), optionally an `...` (always preceded by a comma `,`), followed by a `}` - eg. `{x: Number, y: String}`, `{k: Function, ...}`
+* __Field__ = an `Identifier`, followed by a colon `:`, followed by `Types` - eg. `x: Date | String`, `y: Boolean`
+* __Tuple__ = a `(`, followed by one or more `Types` separated by a comma `,` (trailing comma `,` is permitted), followed by a `)` - eg `(Date)`, `(Number, Date)`
+* __Array__ = a `[` followed by exactly one `Types` followed by a `]` - eg. `[Boolean]`, `[Boolean | Null]`
+
+### Guide
+
+`type-check` uses `Object.toString` to find out the basic type of a value. Specifically,
+
+```js
+{}.toString.call(VALUE).slice(8, -1)
+{}.toString.call(true).slice(8, -1) // 'Boolean'
+```
+A basic type, eg. `Number`, uses this check. This is much more versatile than using `typeof` - for example, with `document`, `typeof` produces `'object'` which isn't that useful, and our technique produces `'HTMLDocument'`.
+
+You may check for multiple types by separating types with a `|`. The checker proceeds from left to right, and passes if the value is any of the types - eg. `String | Boolean` first checks if the value is a string, and then if it is a boolean. If it is none of those, then it returns false.
+
+Adding a `Maybe` in front of a list of multiple types is the same as also checking for `Null` and `Undefined` - eg. `Maybe String` is equivalent to `Undefined | Null | String`.
+
+You may add a comment to remind you of what the type is for by following an identifier with a `::` before a type (or multiple types). The comment is simply thrown out.
+
+The wildcard `*` matches all types.
+
+There are three types of structures for checking the contents of a value: 'fields', 'tuple', and 'array'.
+
+If used by itself, a 'fields' structure will pass with any type of object as long as it is an instance of `Object` and the properties pass - this allows for duck typing - eg. `{x: Boolean}`.
+
+To check if the properties pass, and the value is of a certain type, you can specify the type - eg. `Error{message: String}`.
+
+If you want to make a field optional, you can simply use `Maybe` - eg. `{x: Boolean, y: Maybe String}` will still pass if `y` is undefined (or null).
+
+If you don't care if the value has properties beyond what you have specified, you can use the 'etc' operator `...` - eg. `{x: Boolean, ...}` will match an object with an `x` property that is a boolean, and with zero or more other properties.
+
+For an array, you must specify one or more types (separated by `|`) - it will pass for something of any length as long as each element passes the types provided - eg. `[Number]`, `[Number | String]`.
+
+A tuple checks for a fixed number of elements, each of a potentially different type. Each element is separated by a comma - eg. `(String, Number)`.
+
+An array and tuple structure check that the value is of type `Array` by default, but if another type is specified, they will check for that instead - eg. `Int32Array[Number]`. You can use the wildcard `*` to search for any type at all.
+
+Check out the [type precedence](https://github.com/zaboco/type-precedence) library for type-check.
+
+## Options
+
+Options is an object. It is an optional parameter to the `typeCheck` and `parsedTypeCheck` functions. The only current option is `customTypes`.
+
+
+### Custom Types
+
+__Example:__
+
+```js
+var options = {
+  customTypes: {
+    Even: {
+      typeOf: 'Number',
+      validate: function(x) {
+        return x % 2 === 0;
+      }
+    }
+  }
+};
+typeCheck('Even', 2, options); // true
+typeCheck('Even', 3, options); // false
+```
+
+`customTypes` allows you to set up custom types for validation. The value of this is an object. The keys of the object are the types you will be matching. Each value of the object will be an object having a `typeOf` property - a string, and `validate` property - a function.
+
+The `typeOf` property is the type the value should be, and `validate` is a function which should return true if the value is of that type. `validate` receives one parameter, which is the value that we are checking.
+
+## Technical About
+
+`type-check` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It also uses the [prelude.ls](http://preludels.com/) library.

+
+Wrap your words.

+output:
+
+                        At long last the struggle and tumult
+                        was over. The machines had finally cast

+                        sun was just another point of light.
+
+methods
+=======
+
+var wrap = require('wordwrap');
+
+wrap(stop), wrap(start, stop, params={mode:"soft"})
+---------------------------------------------------
+
+Returns a function that takes a string and returns a new string.
+
+Pad out lines with spaces out to column `start` and then wrap until column
+`stop`. If a word is longer than `stop - start` characters it will overflow.
+
+In "soft" mode, split chunks by `/(\S+\s+/` and don't break up chunks which are
+longer than `stop - start`, in "hard" mode, split chunks with `/\b/` and break
+up chunks longer than `stop - start`.
+
+wrap.hard(start, stop)
+----------------------
+
+Like `wrap()` but with `params.mode = "hard"`.

+In Praise of Idleness
+
+By Bertrand Russell
+
+[1932]
+
+Like most of my generation, I was brought up on the saying: 'Satan finds some mischief for idle hands to do.' Being a highly virtuous child, I believed all that I was told, and acquired a conscience which has kept me working hard down to the present moment. But although my conscience has controlled my actions, my opinions have undergone a revolution. I think that there is far too much work done in the world, that immense harm is caused by the belief that work is virtuous, and that what needs to be preached in modern industrial countries is quite different from what always has been preached. Everyone knows the story of the traveler in Naples who saw twelve beggars lying in the sun (it was before the days of Mussolini), and offered a lira to the laziest of them. Eleven of them jumped up to claim it, so he gave it to the twelfth. this traveler was on the right lines. But in countries which do not enjoy Mediterranean sunshine idleness is more difficult, and a great public propaganda will be required to inaugurate it. I hope that, after reading the following pages, the leaders of the YMCA will start a campaign to induce good young men to do nothing. If so, I shall not have lived in vain.
+
+Before advancing my own arguments for laziness, I must dispose of one which I cannot accept. Whenever a person who already has enough to live on proposes to engage in some everyday kind of job, such as school-teaching or typing, he or she is told that such conduct takes the bread out of other people's mouths, and is therefore wicked. If this argument were valid, it would only be necessary for us all to be idle in order that we should all have our mouths full of bread. What people who say such things forget is that what a man earns he usually spends, and in spending he gives employment. As long as a man spends his income, he puts just as much bread into people's mouths in spending as he takes out of other people's mouths in earning. The real villain, from this point of view, is the man who saves. If he merely puts his savings in a stocking, like the proverbial French peasant, it is obvious that they do not give employment. If he invests his savings, the matter is less obvious, and different cases arise.
+
+One of the commonest things to do with savings is to lend them to some Government. In view of the fact that the bulk of the public expenditure of most civilized Governments consists in payment for past wars or preparation for future wars, the man who lends his money to a Government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man's economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it in drink or gambling.
+
+But, I shall be told, the case is quite different when savings are invested in industrial enterprises. When such enterprises succeed, and produce something useful, this may be conceded. In these days, however, no one will deny that most enterprises fail. That means that a large amount of human labor, which might have been devoted to producing something that could be enjoyed, was expended on producing machines which, when produced, lay idle and did no good to anyone. The man who invests his savings in a concern that goes bankrupt is therefore injuring others as well as himself. If he spent his money, say, in giving parties for his friends, they (we may hope) would get pleasure, and so would all those upon whom he spent money, such as the butcher, the baker, and the bootlegger. But if he spends it (let us say) upon laying down rails for surface card in some place where surface cars turn out not to be wanted, he has diverted a mass of labor into channels where it gives pleasure to no one. Nevertheless, when he becomes poor through failure of his investment he will be regarded as a victim of undeserved misfortune, whereas the gay spendthrift, who has spent his money philanthropically, will be despised as a fool and a frivolous person.
+
+All this is only preliminary. I want to say, in all seriousness, that a great deal of harm is being done in the modern world by belief in the virtuousness of work, and that the road to happiness and prosperity lies in an organized diminution of work.
+
+First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid. The second kind is capable of indefinite extension: there are not only those who give orders, but those who give advice as to what orders should be given. Usually two opposite kinds of advice are given simultaneously by two organized bodies of men; this is called politics. The skill required for this kind of work is not knowledge of the subjects as to which advice is given, but knowledge of the art of persuasive speaking and writing, i.e. of advertising.
+
+Throughout Europe, though not in America, there is a third class of men, more respected than either of the classes of workers. There are men who, through ownership of land, are able to make others pay for the privilege of being allowed to exist and to work. These landowners are idle, and I might therefore be expected to praise them. Unfortunately, their idleness is only rendered possible by the industry of others; indeed their desire for comfortable idleness is historically the source of the whole gospel of work. The last thing they have ever wished is that others should follow their example.
+
+From the beginning of civilization until the Industrial Revolution, a man could, as a rule, produce by hard work little more than was required for the subsistence of himself and his family, although his wife worked at least as hard as he did, and his children added their labor as soon as they were old enough to do so. The small surplus above bare necessaries was not left to those who produced it, but was appropriated by warriors and priests. In times of famine there was no surplus; the warriors and priests, however, still secured as much as at other times, with the result that many of the workers died of hunger. This system persisted in Russia until 1917 [1], and still persists in the East; in England, in spite of the Industrial Revolution, it remained in full force throughout the Napoleonic wars, and until a hundred years ago, when the new class of manufacturers acquired power. In America, the system came to an end with the Revolution, except in the South, where it persisted until the Civil War. A system which lasted so long and ended so recently has naturally left a profound impress upon men's thoughts and opinions. Much that we take for granted about the desirability of work is derived from this system, and, being pre-industrial, is not adapted to the modern world. Modern technique has made it possible for leisure, within limits, to be not the prerogative of small privileged classes, but a right evenly distributed throughout the community. The morality of work is the morality of slaves, and the modern world has no need of slavery.
+
+It is obvious that, in primitive communities, peasants, left to themselves, would not have parted with the slender surplus upon which the warriors and priests subsisted, but would have either produced less or consumed more. At first, sheer force compelled them to produce and part with the surplus. Gradually, however, it was found possible to induce many of them to accept an ethic according to which it was their duty to work hard, although part of their work went to support others in idleness. By this means the amount of compulsion required was lessened, and the expenses of government were diminished. To this day, 99 per cent of British wage-earners would be genuinely shocked if it were proposed that the King should not have a larger income than a working man. The conception of duty, speaking historically, has been a means used by the holders of power to induce others to live for the interests of their masters rather than for their own. Of course the holders of power conceal this fact from themselves by managing to believe that their interests are identical with the larger interests of humanity. Sometimes this is true; Athenian slave-owners, for instance, employed part of their leisure in making a permanent contribution to civilization which would have been impossible under a just economic system. Leisure is essential to civilization, and in former times leisure for the few was only rendered possible by the labors of the many. But their labors were valuable, not because work is good, but because leisure is good. And with modern technique it would be possible to distribute leisure justly without injury to civilization.
+
+Modern technique has made it possible to diminish enormously the amount of labor required to secure the necessaries of life for everyone. This was made obvious during the war. At that time all the men in the armed forces, and all the men and women engaged in the production of munitions, all the men and women engaged in spying, war propaganda, or Government offices connected with the war, were withdrawn from productive occupations. In spite of this, the general level of well-being among unskilled wage-earners on the side of the Allies was higher than before or since. The significance of this fact was concealed by finance: borrowing made it appear as if the future was nourishing the present. But that, of course, would have been impossible; a man cannot eat a loaf of bread that does not yet exist. The war showed conclusively that, by the scientific organization of production, it is possible to keep modern populations in fair comfort on a small part of the working capacity of the modern world. If, at the end of the war, the scientific organization, which had been created in order to liberate men for fighting and munition work, had been preserved, and the hours of the week had been cut down to four, all would have been well. Instead of that the old chaos was restored, those whose work was demanded were made to work long hours, and the rest were left to starve as unemployed. Why? Because work is a duty, and a man should not receive wages in proportion to what he has produced, but in proportion to his virtue as exemplified by his industry.
+
+This is the morality of the Slave State, applied in circumstances totally unlike those in which it arose. No wonder the result has been disastrous. Let us take an illustration. Suppose that, at a given moment, a certain number of people are engaged in the manufacture of pins. They make as many pins as the world needs, working (say) eight hours a day. Someone makes an invention by which the same number of men can make twice as many pins: pins are already so cheap that hardly any more will be bought at a lower price. In a sensible world, everybody concerned in the manufacturing of pins would take to working four hours instead of eight, and everything else would go on as before. But in the actual world this would be thought demoralizing. The men still work eight hours, there are too many pins, some employers go bankrupt, and half the men previously concerned in making pins are thrown out of work. There is, in the end, just as much leisure as on the other plan, but half the men are totally idle while half are still overworked. In this way, it is insured that the unavoidable leisure shall cause misery all round instead of being a universal source of happiness. Can anything more insane be imagined?
+
+The idea that the poor should have leisure has always been shocking to the rich. In England, in the early nineteenth century, fifteen hours was the ordinary day's work for a man; children sometimes did as much, and very commonly did twelve hours a day. When meddlesome busybodies suggested that perhaps these hours were rather long, they were told that work kept adults from drink and children from mischief. When I was a child, shortly after urban working men had acquired the vote, certain public holidays were established by law, to the great indignation of the upper classes. I remember hearing an old Duchess say: 'What do the poor want with holidays? They ought to work.' People nowadays are less frank, but the sentiment persists, and is the source of much of our economic confusion.
+
+Let us, for a moment, consider the ethics of work frankly, without superstition. Every human being, of necessity, consumes, in the course of his life, a certain amount of the produce of human labor. Assuming, as we may, that labor is on the whole disagreeable, it is unjust that a man should consume more than he produces. Of course he may provide services rather than commodities, like a medical man, for example; but he should provide something in return for his board and lodging. to this extent, the duty of work must be admitted, but to this extent only.
+
+I shall not dwell upon the fact that, in all modern societies outside the USSR, many people escape even this minimum amount of work, namely all those who inherit money and all those who marry money. I do not think the fact that these people are allowed to be idle is nearly so harmful as the fact that wage-earners are expected to overwork or starve.
+
+If the ordinary wage-earner worked four hours a day, there would be enough for everybody and no unemployment -- assuming a certain very moderate amount of sensible organization. This idea shocks the well-to-do, because they are convinced that the poor would not know how to use so much leisure. In America men often work long hours even when they are well off; such men, naturally, are indignant at the idea of leisure for wage-earners, except as the grim punishment of unemployment; in fact, they dislike leisure even for their sons. Oddly enough, while they wish their sons to work so hard as to have no time to be civilized, they do not mind their wives and daughters having no work at all. the snobbish admiration of uselessness, which, in an aristocratic society, extends to both sexes, is, under a plutocracy, confined to women; this, however, does not make it any more in agreement with common sense.
+
+The wise use of leisure, it must be conceded, is a product of civilization and education. A man who has worked long hours all his life will become bored if he becomes suddenly idle. But without a considerable amount of leisure a man is cut off from many of the best things. There is no longer any reason why the bulk of the population should suffer this deprivation; only a foolish asceticism, usually vicarious, makes us continue to insist on work in excessive quantities now that the need no longer exists.
+
+In the new creed which controls the government of Russia, while there is much that is very different from the traditional teaching of the West, there are some things that are quite unchanged. The attitude of the governing classes, and especially of those who conduct educational propaganda, on the subject of the dignity of labor, is almost exactly that which the governing classes of the world have always preached to what were called the 'honest poor'. Industry, sobriety, willingness to work long hours for distant advantages, even submissiveness to authority, all these reappear; moreover authority still represents the will of the Ruler of the Universe, Who, however, is now called by a new name, Dialectical Materialism.
+
+The victory of the proletariat in Russia has some points in common with the victory of the feminists in some other countries. For ages, men had conceded the superior saintliness of women, and had consoled women for their inferiority by maintaining that saintliness is more desirable than power. At last the feminists decided that they would have both, since the pioneers among them believed all that the men had told them about the desirability of virtue, but not what they had told them about the worthlessness of political power. A similar thing has happened in Russia as regards manual work. For ages, the rich and their sycophants have written in praise of 'honest toil', have praised the simple life, have professed a religion which teaches that the poor are much more likely to go to heaven than the rich, and in general have tried to make manual workers believe that there is some special nobility about altering the position of matter in space, just as men tried to make women believe that they derived some special nobility from their sexual enslavement. In Russia, all this teaching about the excellence of manual work has been taken seriously, with the result that the manual worker is more honored than anyone else. What are, in essence, revivalist appeals are made, but not for the old purposes: they are made to secure shock workers for special tasks. Manual work is the ideal which is held before the young, and is the basis of all ethical teaching.
+
+For the present, possibly, this is all to the good. A large country, full of natural resources, awaits development, and has has to be developed with very little use of credit. In these circumstances, hard work is necessary, and is likely to bring a great reward. But what will happen when the point has been reached where everybody could be comfortable without working long hours?
+
+In the West, we have various ways of dealing with this problem. We have no attempt at economic justice, so that a large proportion of the total produce goes to a small minority of the population, many of whom do no work at all. Owing to the absence of any central control over production, we produce hosts of things that are not wanted. We keep a large percentage of the working population idle, because we can dispense with their labor by making the others overwork. When all these methods prove inadequate, we have a war: we cause a number of people to manufacture high explosives, and a number of others to explode them, as if we were children who had just discovered fireworks. By a combination of all these devices we manage, though with difficulty, to keep alive the notion that a great deal of severe manual work must be the lot of the average man.
+
+In Russia, owing to more economic justice and central control over production, the problem will have to be differently solved. the rational solution would be, as soon as the necessaries and elementary comforts can be provided for all, to reduce the hours of labor gradually, allowing a popular vote to decide, at each stage, whether more leisure or more goods were to be preferred. But, having taught the supreme virtue of hard work, it is difficult to see how the authorities can aim at a paradise in which there will be much leisure and little work. It seems more likely that they will find continually fresh schemes, by which present leisure is to be sacrificed to future productivity. I read recently of an ingenious plan put forward by Russian engineers, for making the White Sea and the northern coasts of Siberia warm, by putting a dam across the Kara Sea. An admirable project, but liable to postpone proletarian comfort for a generation, while the nobility of toil is being displayed amid the ice-fields and snowstorms of the Arctic Ocean. This sort of thing, if it happens, will be the result of regarding the virtue of hard work as an end in itself, rather than as a means to a state of affairs in which it is no longer needed.
+
+The fact is that moving matter about, while a certain amount of it is necessary to our existence, is emphatically not one of the ends of human life. If it were, we should have to consider every navvy superior to Shakespeare. We have been misled in this matter by two causes. One is the necessity of keeping the poor contented, which has led the rich, for thousands of years, to preach the dignity of labor, while taking care themselves to remain undignified in this respect. The other is the new pleasure in mechanism, which makes us delight in the astonishingly clever changes that we can produce on the earth's surface. Neither of these motives makes any great appeal to the actual worker. If you ask him what he thinks the best part of his life, he is not likely to say: 'I enjoy manual work because it makes me feel that I am fulfilling man's noblest task, and because I like to think how much man can transform his planet. It is true that my body demands periods of rest, which I have to fill in as best I may, but I am never so happy as when the morning comes and I can return to the toil from which my contentment springs.' I have never heard working men say this sort of thing. They consider work, as it should be considered, a necessary means to a livelihood, and it is from their leisure that they derive whatever happiness they may enjoy.
+
+It will be said that, while a little leisure is pleasant, men would not know how to fill their days if they had only four hours of work out of the twenty-four. In so far as this is true in the modern world, it is a condemnation of our civilization; it would not have been true at any earlier period. There was formerly a capacity for light-heartedness and play which has been to some extent inhibited by the cult of efficiency. The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake. Serious-minded persons, for example, are continually condemning the habit of going to the cinema, and telling us that it leads the young into crime. But all the work that goes to producing a cinema is respectable, because it is work, and because it brings a money profit. The notion that the desirable activities are those that bring a profit has made everything topsy-turvy. The butcher who provides you with meat and the baker who provides you with bread are praiseworthy, because they are making money; but when you enjoy the food they have provided, you are merely frivolous, unless you eat only to get strength for your work. Broadly speaking, it is held that getting money is good and spending money is bad. Seeing that they are two sides of one transaction, this is absurd; one might as well maintain that keys are good, but keyholes are bad. Whatever merit there may be in the production of goods must be entirely derivative from the advantage to be obtained by consuming them. The individual, in our society, works for profit; but the social purpose of his work lies in the consumption of what he produces. It is this divorce between the individual and the social purpose of production that makes it so difficult for men to think clearly in a world in which profit-making is the incentive to industry. We think too much of production, and too little of consumption. One result is that we attach too little importance to enjoyment and simple happiness, and that we do not judge production by the pleasure that it gives to the consumer.
+
+When I suggest that working hours should be reduced to four, I am not meaning to imply that all the remaining time should necessarily be spent in pure frivolity. I mean that four hours' work a day should entitle a man to the necessities and elementary comforts of life, and that the rest of his time should be his to use as he might see fit. It is an essential part of any such social system that education should be carried further than it usually is at present, and should aim, in part, at providing tastes which would enable a man to use leisure intelligently. I am not thinking mainly of the sort of things that would be considered 'highbrow'. Peasant dances have died out except in remote rural areas, but the impulses which caused them to be cultivated must still exist in human nature. The pleasures of urban populations have become mainly passive: seeing cinemas, watching football matches, listening to the radio, and so on. This results from the fact that their active energies are fully taken up with work; if they had more leisure, they would again enjoy pleasures in which they took an active part.
+
+In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges. These facts greatly diminished its excellence, but in spite of this drawback it contributed nearly the whole of what we call civilization. It cultivated the arts and discovered the sciences; it wrote the books, invented the philosophies, and refined social relations. Even the liberation of the oppressed has usually been inaugurated from above. Without the leisure class, mankind would never have emerged from barbarism.
+
+The method of a leisure class without duties was, however, extraordinarily wasteful. None of the members of the class had to be taught to be industrious, and the class as a whole was not exceptionally intelligent. The class might produce one Darwin, but against him had to be set tens of thousands of country gentlemen who never thought of anything more intelligent than fox-hunting and punishing poachers. At present, the universities are supposed to provide, in a more systematic way, what the leisure class provided accidentally and as a by-product. This is a great improvement, but it has certain drawbacks. University life is so different from life in the world at large that men who live in academic milieu tend to be unaware of the preoccupations and problems of ordinary men and women; moreover their ways of expressing themselves are usually such as to rob their opinions of the influence that they ought to have upon the general public. Another disadvantage is that in universities studies are organized, and the man who thinks of some original line of research is likely to be discouraged. Academic institutions, therefore, useful as they are, are not adequate guardians of the interests of civilization in a world where everyone outside their walls is too busy for unutilitarian pursuits.
+
+In a world where no one is compelled to work more than four hours a day, every person possessed of scientific curiosity will be able to indulge it, and every painter will be able to paint without starving, however excellent his pictures may be. Young writers will not be obliged to draw attention to themselves by sensational pot-boilers, with a view to acquiring the economic independence needed for monumental works, for which, when the time at last comes, they will have lost the taste and capacity. Men who, in their professional work, have become interested in some phase of economics or government, will be able to develop their ideas without the academic detachment that makes the work of university economists often seem lacking in reality. Medical men will have the time to learn about the progress of medicine, teachers will not be exasperatedly struggling to teach by routine methods things which they learnt in their youth, which may, in the interval, have been proved to be untrue.
+
+Above all, there will be happiness and joy of life, instead of frayed nerves, weariness, and dyspepsia. The work exacted will be enough to make leisure delightful, but not enough to produce exhaustion. Since men will not be tired in their spare time, they will not demand only such amusements as are passive and vapid. At least one per cent will probably devote the time not spent in professional work to pursuits of some public importance, and, since they will not depend upon these pursuits for their livelihood, their originality will be unhampered, and there will be no need to conform to the standards set by elderly pundits. But it is not only in these exceptional cases that the advantages of leisure will appear. Ordinary men and women, having the opportunity of a happy life, will become more kindly and less persecuting and less inclined to view others with suspicion. The taste for war will die out, partly for this reason, and partly because it will involve long and severe work for all. Good nature is, of all moral qualities, the one that the world needs most, and good nature is the result of ease and security, not of a life of arduous struggle. Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish forever.

+# strip-json-comments [![Build Status](https://travis-ci.org/sindresorhus/strip-json-comments.svg?branch=master)](https://travis-ci.org/sindresorhus/strip-json-comments)
+
+> Strip comments from JSON. Lets you use comments in your JSON files!
+
+This is now possible:
+
+```js
+{
+	// rainbows
+	"unicorn": /* ❤ */ "cake"
+}
+```
+
+It will remove single-line comments `//` and multi-line comments `/**/`.
+
+Also available as a [gulp](https://github.com/sindresorhus/gulp-strip-json-comments)/[grunt](https://github.com/sindresorhus/grunt-strip-json-comments)/[broccoli](https://github.com/sindresorhus/broccoli-strip-json-comments) plugin and a [require hook](https://github.com/uTest/autostrip-json-comments).
+
+
+*There's already [json-comments](https://npmjs.org/package/json-comments), but it's only for Node.js and uses a naive regex to strip comments which fails on simple cases like `{"a":"//"}`. This module however parses out the comments.*
+
+
+## Install
+
+```sh
+$ npm install --save strip-json-comments
+```
+
+```sh
+$ bower install --save strip-json-comments
+```
+
+```sh
+$ component install sindresorhus/strip-json-comments
+```
+
+
+## Usage
+
+```js
+var json = '{/*rainbows*/"unicorn":"cake"}';
+JSON.parse(stripJsonComments(json));
+//=> {unicorn: 'cake'}
+```
+
+
+## API
+
+### stripJsonComments(input)
+
+#### input
+
+Type: `string`
+
+Accepts a string with JSON and returns a string without comments.
+
+
+## CLI
+
+```sh
+$ npm install --global strip-json-comments
+```
+
+```sh
+$ strip-json-comments --help
+
+strip-json-comments input-file > output-file
+# or
+strip-json-comments < input-file > output-file
+```

+```
+
+# methods
+
+``` js
+var table = require('text-table')
+```
+
+## var s = table(rows, opts={})
+
+Return a formatted table string `s` from an array of `rows` and some options
+`opts`.
+
+`rows` should be an array of arrays containing strings, numbers, or other
+printable values.
+
+options can be:
+
+* `opts.hsep` - separator to use between columns, default `'  '`
+* `opts.align` - array of alignment types for each column, default `['l','l',...]`
+* `opts.stringLength` - callback function to use when calculating the string length
+
+alignment types are:
+
+* `'l'` - left
+* `'r'` - right
+* `'c'` - center
+* `'.'` - decimal
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install text-table
+```
+
+# Use with ANSI-colors
+
+Since the string length of ANSI color schemes does not equal the length
+JavaScript sees internally it is necessary to pass the a custom string length
+calculator during the main function call.
+
+See the `test/ansi-colors.js` file for an example.
