+
+## 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'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre  {   in{nest}   }  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' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: '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', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+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 `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.
+

+
+**BigInteger.js** is an arbitrary-length integer library for Javascript, allowing arithmetic operations on integers of unlimited size, notwithstanding memory and time limitations.
+
+**Update (December 2, 2018):** [`BigInt` is being added as a native feature of JavaScript](https://tc39.github.io/proposal-bigint/). This library now works as a polyfill: if the environment supports the native `BigInt`, this library acts as a thin wrapper over the native implementation.
+
+## Installation
+
+If you are using a browser, you can download [BigInteger.js from GitHub](http://peterolson.github.com/BigInteger.js/BigInteger.min.js) or just hotlink to it:
+
+	<script src="https://peterolson.github.io/BigInteger.js/BigInteger.min.js"></script>
+
+If you are using node, you can install BigInteger with [npm](https://npmjs.org/).
+
+    npm install big-integer
+
+Then you can include it in your code:
+
+	var bigInt = require("big-integer");
+
+
+## Usage
+### `bigInt(number, [base], [alphabet], [caseSensitive])`
+
+You can create a bigInt by calling the `bigInt` function. You can pass in
+
+ - a string, which it will parse as an bigInt and throw an `"Invalid integer"` error if the parsing fails.
+ - a Javascript number, which it will parse as an bigInt and throw an `"Invalid integer"` error if the parsing fails.
+ - another bigInt.
+ - nothing, and it will return `bigInt.zero`.
+
+ If you provide a second parameter, then it will parse `number` as a number in base `base`. Note that `base` can be any bigInt (even negative or zero). The letters "a-z" and "A-Z" will be interpreted as the numbers 10 to 35. Higher digits can be specified in angle brackets (`<` and `>`). The default `base` is `10`.
+
+ You can specify a custom alphabet for base conversion with the third parameter. The default `alphabet` is `"0123456789abcdefghijklmnopqrstuvwxyz"`.
+
+ The fourth parameter specifies whether or not the number string should be case-sensitive, i.e. whether `a` and `A` should be treated as different digits. By default `caseSensitive` is `false`.
+
+Examples:
+
+    var zero = bigInt();
+    var ninetyThree = bigInt(93);
+	var largeNumber = bigInt("75643564363473453456342378564387956906736546456235345");
+	var googol = bigInt("1e100");
+	var bigNumber = bigInt(largeNumber);
+
+	var maximumByte = bigInt("FF", 16);
+	var fiftyFiveGoogol = bigInt("<55>0", googol);
+
+Note that Javascript numbers larger than `9007199254740992` and smaller than `-9007199254740992` are not precisely represented numbers and will not produce exact results. If you are dealing with numbers outside that range, it is better to pass in strings.
+
+### Method Chaining
+
+Note that bigInt operations return bigInts, which allows you to chain methods, for example:
+
+    var salary = bigInt(dollarsPerHour).times(hoursWorked).plus(randomBonuses)
+
+### Constants
+
+There are three named constants already stored that you do not have to construct with the `bigInt` function yourself:
+
+ - `bigInt.one`, equivalent to `bigInt(1)`
+ - `bigInt.zero`, equivalent to `bigInt(0)`
+ - `bigInt.minusOne`, equivalent to `bigInt(-1)`
+
+The numbers from -999 to 999 are also already prestored and can be accessed using `bigInt[index]`, for example:
+
+ - `bigInt[-999]`, equivalent to `bigInt(-999)`
+ - `bigInt[256]`, equivalent to `bigInt(256)`
+
+### Methods

+
+#### `isEven()`

+ - `bigInt(6).isPrime()` => `false`
+
+#### `isProbablePrime([iterations], [rng])`
+
+Returns `true` if the number is very likely to be prime, `false` otherwise.
+Supplying `iterations` is optional - it determines the number of iterations of the test (default: `5`). The more iterations, the lower chance of getting a false positive.
+This uses the [Miller Rabin test](https://en.wikipedia.org/wiki/Miller%E2%80%93Rabin_primality_test).
+
+ - `bigInt(5).isProbablePrime()` => `true`
+ - `bigInt(49).isProbablePrime()` => `false`
+ - `bigInt(1729).isProbablePrime()` => `false`
+
+Note that this function is not deterministic, since it relies on random sampling of factors, so the result for some numbers is not always the same - unless you pass a predictable random number generator as `rng`. The behavior and requirements are the same as with `randBetween`.
+
+ - `bigInt(1729).isProbablePrime(1, () => 0.1)` => `false`
+ - `bigInt(1729).isProbablePrime(1, () => 0.2)` => `true`
+
+If the number is composite then the Miller–Rabin primality test declares the number probably prime with a probability at most `4` to the power `−iterations`.
+If the number is prime, this function always returns `true`.

+
+### Override Methods
+
+#### `toString(radix = 10, [alphabet])`
+
+Converts a bigInt to a string. There is an optional radix parameter (which defaults to 10) that converts the number to the given radix. Digits in the range `10-35` will use the letters `a-z`.
+
+ - `bigInt("1e9").toString()` => `"1000000000"`
+ - `bigInt("1e9").toString(16)` => `"3b9aca00"`
+
+ You can use a custom base alphabet with the second parameter. The default `alphabet` is `"0123456789abcdefghijklmnopqrstuvwxyz"`.
+
+  - `bigInt("5").toString(2, "aA")` => `"AaA"`
+
+**Note that arithmetical operators will trigger the `valueOf` function rather than the `toString` function.** When converting a bigInteger to a string, you should use the `toString` method or the `String` function instead of adding the empty string.
+
+ - `bigInt("999999999999999999").toString()` => `"999999999999999999"`
+ - `String(bigInt("999999999999999999"))` => `"999999999999999999"`

+
+Negative bases are also supported.
+
+ - `bigInt(12345).toString(-10)` => `"28465"`
+
+Base 1 and base -1 are also supported.
+
+ - `bigInt(-15).toString(1)` => `"-111111111111111"`
+ - `bigInt(-15).toString(-1)` => `"101010101010101010101010101010"`
+
+Base 0 is only allowed for the number zero.
+
+ - `bigInt(0).toString(0)` => `0`
+ - `bigInt(1).toString(0)` => `Error: Cannot convert nonzero numbers to base 0.`
+
+[View benchmarks for this method](http://peterolson.github.io/BigInteger.js/benchmark/#toString)
+
+#### `valueOf()`
+
+Converts a bigInt to a native Javascript number. This override allows you to use native arithmetic operators without explicit conversion:
+
+ - `bigInt("100") + bigInt("200") === 300; //true`

+# Introduction
+
+Bluebird is a fully featured promise library with focus on innovative features and performance
+
+See the [**bluebird website**](http://bluebirdjs.com/docs/getting-started.html) for further documentation, references and instructions. See the [**API reference**](http://bluebirdjs.com/docs/api-reference.html) here.
+
+For bluebird 2.x documentation and files, see the [2.x tree](https://github.com/petkaantonov/bluebird/tree/2.x).
+
+# Questions and issues
+
+The [github issue tracker](https://github.com/petkaantonov/bluebird/issues) is **_only_** for bug reports and feature requests. Anything else, such as questions for help in using the library, should be posted in [StackOverflow](http://stackoverflow.com/questions/tagged/bluebird) under tags `promise` and `bluebird`.

+
+[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)
+[![downloads](https://img.shields.io/npm/dm/brace-expansion.svg)](https://www.npmjs.org/package/brace-expansion)
+[![Greenkeeper badge](https://badges.greenkeeper.io/juliangruber/brace-expansion.svg)](https://greenkeeper.io/)
+
+[![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
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {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
+```

+
+[![Build Status][travis-image]][travis-url]
+[![NPM Version][npm-image]][npm-url]
+[![NPM Downloads][downloads-image]][downloads-url]
+
+This is a polyfill for [`Buffer#indexOf`](https://nodejs.org/api/buffer.html#buffer_buf_indexof_value_byteoffset) and Buffer#lastIndexOf introduced in NodeJS 4.0.
+
+## Example
+
+```js
+require("buffer-indexof-polyfill");
+
+new Buffer("buffer").indexOf("uff") // return 1
+new Buffer("buffer").indexOf("abc") // return -1
+```
+
+## Installation
+
+```bash
+npm install buffer-indexof-polyfill
+```

+
+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.

+
+Times out a request in the Connect/Express application framework.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install connect-timeout
+```
+
+## API
+
+**NOTE** This module is not recommend as a "top-level" middleware (i.e.
+`app.use(timeout('5s'))`) unless you take precautions to halt your own
+middleware processing. See [as top-level middleware](#as-top-level-middleware)
+for how to use as a top-level middleware.
+
+While the library will emit a 'timeout' event when requests exceed the given
+timeout, node will continue processing the slow request until it terminates.
+Slow requests will continue to use CPU and memory, even if you are returning
+a HTTP response in the timeout callback. For better control over CPU/memory,
+you may need to find the events that are taking a long time (3rd party HTTP
+requests, disk I/O, database calls) and find a way to cancel them, and/or
+close the attached sockets.
+
+### timeout(time, [options])
+
+Returns middleware that times out in `time` milliseconds. `time` can also
+be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
+module. On timeout, `req` will emit `"timeout"`.
+
+#### Options
+
+The `timeout` function takes an optional `options` object that may contain
+any of the following keys:
+
+##### respond
+
+Controls if this module will "respond" in the form of forwarding an error.
+If `true`, the timeout error is passed to `next()` so that you may customize
+the response behavior. This error has a `.timeout` property as well as
+`.status == 503`. This defaults to `true`.
+
+### req.clearTimeout()
+
+Clears the timeout on the request. The timeout is completely removed and
+will not fire for this request in the future.
+
+### req.timedout
+
+`true` if timeout fired; `false` otherwise.
+
+## Examples
+
+### as top-level middleware
+
+Because of the way middleware processing works, once this module
+passes the request to the next middleware (which it has to do in order
+for you to do work), it can no longer stop the flow, so you must take
+care to check if the request has timedout before you continue to act
+on the request.
+
+```javascript
+var bodyParser = require('body-parser')
+var cookieParser = require('cookie-parser')
+var express = require('express')
+var timeout = require('connect-timeout')
+
+// example of using this top-level; note the use of haltOnTimedout
+// after every middleware; it will stop the request flow on a timeout
+var app = express()
+app.use(timeout('5s'))
+app.use(bodyParser())
+app.use(haltOnTimedout)
+app.use(cookieParser())
+app.use(haltOnTimedout)
+
+// Add your routes here, etc.
+
+function haltOnTimedout (req, res, next) {
+  if (!req.timedout) next()
+}
+
+app.listen(3000)
+```
+
+### express 3.x
+
+```javascript
+var express = require('express')
+var bodyParser = require('body-parser')
+var timeout = require('connect-timeout')
+
+var app = express()
+app.post('/save', timeout('5s'), bodyParser.json(), haltOnTimedout, function (req, res, next) {
+  savePost(req.body, function (err, id) {
+    if (err) return next(err)
+    if (req.timedout) return
+    res.send('saved as id ' + id)
+  })
+})
+
+function haltOnTimedout (req, res, next) {
+  if (!req.timedout) next()
+}
+
+function savePost (post, cb) {
+  setTimeout(function () {
+    cb(null, ((Math.random() * 40000) >>> 0))
+  }, (Math.random() * 7000) >>> 0)
+}
+
+app.listen(3000)
+```
+
+### connect
+
+```javascript
+var bodyParser = require('body-parser')
+var connect = require('connect')
+var timeout = require('connect-timeout')
+
+var app = connect()
+app.use('/save', timeout('5s'), bodyParser.json(), haltOnTimedout, function (req, res, next) {
+  savePost(req.body, function (err, id) {
+    if (err) return next(err)
+    if (req.timedout) return
+    res.send('saved as id ' + id)
+  })
+})
+
+function haltOnTimedout (req, res, next) {
+  if (!req.timedout) next()
+}
+
+function savePost (post, cb) {
+  setTimeout(function () {
+    cb(null, ((Math.random() * 40000) >>> 0))
+  }, (Math.random() * 7000) >>> 0)

+
+Create HTTP errors for Express, Koa, Connect, etc. with ease.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install http-errors
+```
+
+## Example
+
+```js
+var createError = require('http-errors')
+var express = require('express')
+var app = express()
+
+app.use(function (req, res, next) {
+  if (!req.user) return next(createError(401, 'Please login to view this page.'))
+  next()
+})
+```
+
+## API
+
+This is the current API, currently extracted from Koa and subject to change.
+
+All errors inherit from JavaScript `Error` and the exported `createError.HttpError`.
+
+### Error Properties
+
+- `expose` - can be used to signal if `message` should be sent to the client,
+  defaulting to `false` when `status` >= 500
+- `headers` - can be an object of header names to values to be sent to the
+  client, defaulting to `undefined`. When defined, the key names should all
+  be lower-cased
+- `message` - the traditional error message, which should be kept short and all
+  single line
+- `status` - the status code of the error, mirroring `statusCode` for general
+  compatibility
+- `statusCode` - the status code of the error, defaulting to `500`
+
+### createError([status], [message], [properties])
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var err = createError(404, 'This video does not exist!')
+```
+
+- `status: 500` - the status code as a number
+- `message` - the message of the error, defaulting to node's text for that status code.
+- `properties` - custom properties to attach to the object
+
+### new createError\[code || name\](\[msg]\))
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var err = new createError.NotFound()
+```
+
+- `code` - the status code as a number
+- `name` - the name of the error as a "bumpy case", i.e. `NotFound` or `InternalServerError`.
+
+#### List of all constructors

+# Polyfill for `Object.setPrototypeOf`
+
+A simple cross platform implementation to set the prototype of an instianted object.  Supports all modern browsers and at least back to IE8.
+
+## Usage:
+
+```
+$ npm install --save setprototypeof
+```
+
+```javascript
+var setPrototypeOf = require('setprototypeof');
+
+var obj = {};
+setPrototypeOf(obj, {
+	foo: function() {
+		return 'bar';
+	}
+});
+obj.foo(); // bar
+```
+
+TypeScript is also supported:
+```typescript
+import setPrototypeOf = require('setprototypeof');
+```

+
+Like [duplexer](https://github.com/Raynos/duplexer) but using Streams3
+
+```javascript
+var stream = require("stream");
+
+var duplexer2 = require("duplexer2");
+
+var writable = new stream.Writable({objectMode: true}),
+    readable = new stream.Readable({objectMode: true});
+
+writable._write = function _write(input, encoding, done) {
+  if (readable.push(input)) {
+    return done();
+  } else {
+    readable.once("drain", done);
+  }
+};
+
+readable._read = function _read(n) {
+  // no-op
+};
+
+// simulate the readable thing closing after a bit
+writable.once("finish", function() {
+  setTimeout(function() {
+    readable.push(null);
+  }, 500);
+});
+
+var duplex = duplexer2(writable, readable);
+
+duplex.on("data", function(e) {
+  console.log("got data", JSON.stringify(e));
+});
+
+duplex.on("finish", function() {
+  console.log("got finish event");
+});
+
+duplex.on("end", function() {
+  console.log("got end event");
+});
+
+duplex.write("oh, hi there", function() {
+  console.log("finished writing");
+});
+
+duplex.end(function() {
+  console.log("finished ending");
+});
+```
+
+```
+got data "oh, hi there"
+finished writing
+got finish event
+finished ending
+got end event
+```
+
+## Overview
+
+This is a reimplementation of [duplexer](https://www.npmjs.com/package/duplexer) using the
+Streams3 API which is standard in Node as of v4. Everything largely
+works the same.
+
+
+
+## Installation
+
+[Available via `npm`](https://docs.npmjs.com/cli/install):
+
+```
+$ npm i duplexer2
+```
+
+## API
+
+### duplexer2
+
+Creates a new `DuplexWrapper` object, which is the actual class that implements
+most of the fun stuff. All that fun stuff is hidden. DON'T LOOK.
+
+```javascript
+duplexer2([options], writable, readable)
+```
+
+```javascript
+const duplex = duplexer2(new stream.Writable(), new stream.Readable());
+```
+
+Arguments
+
+* __options__ - an object specifying the regular `stream.Duplex` options, as
+  well as the properties described below.
+* __writable__ - a writable stream
+* __readable__ - a readable stream
+
+Options
+
+* __bubbleErrors__ - a boolean value that specifies whether to bubble errors
+  from the underlying readable/writable streams. Default is `true`.
+

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+
+

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

+
+***Node-core v8.9.4 string_decoder for userland***
+
+
+[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash
+npm install --save string_decoder
+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+# fs.realpath
+
+A backwards-compatible fs.realpath for Node v6 and above
+
+In Node v6, the JavaScript implementation of fs.realpath was replaced
+with a faster (but less resilient) native implementation.  That raises
+new and platform-specific errors and cannot handle long or excessively
+symlink-looping paths.
+
+This module handles those cases by detecting the new errors and
+falling back to the JavaScript implementation.  On versions of Node
+prior to v6, it has no effect.
+
+## USAGE
+
+```js
+var rp = require('fs.realpath')
+
+// async version
+rp.realpath(someLongAndLoopingPath, function (er, real) {
+  // the ELOOP was handled, but it was a bit slower
+})
+
+// sync version
+var real = rp.realpathSync(someLongAndLoopingPath)
+
+// monkeypatch at your own risk!
+// This replaces the fs.realpath/fs.realpathSync builtins
+rp.monkeypatch()
+
+// un-do the monkeypatching
+rp.unmonkeypatch()
+```

+Like FS streams, but with stat on them, and supporting directories and
+symbolic links, as well as normal files.  Also, you can use this to set
+the stats on a file, even if you don't change its contents, or to create
+a symlink, etc.
+
+So, for example, you can "write" a directory, and it'll call `mkdir`.  You
+can specify a uid and gid, and it'll call `chown`.  You can specify a
+`mtime` and `atime`, and it'll call `utimes`.  You can call it a symlink
+and provide a `linkpath` and it'll call `symlink`.
+
+Note that it won't automatically resolve symbolic links.  So, if you
+call `fstream.Reader('/some/symlink')` then you'll get an object
+that stats and then ends immediately (since it has no data).  To follow
+symbolic links, do this: `fstream.Reader({path:'/some/symlink', follow:
+true })`.
+
+There are various checks to make sure that the bytes emitted are the
+same as the intended size, if the size is set.
+
+## Examples
+
+```javascript
+fstream
+  .Writer({ path: "path/to/file"
+          , mode: 0755
+          , size: 6
+          })
+  .write("hello\n")
+  .end()
+```
+
+This will create the directories if they're missing, and then write
+`hello\n` into the file, chmod it to 0755, and assert that 6 bytes have
+been written when it's done.
+
+```javascript
+fstream
+  .Writer({ path: "path/to/file"
+          , mode: 0755
+          , size: 6
+          , flags: "a"
+          })
+  .write("hello\n")
+  .end()
+```
+
+You can pass flags in, if you want to append to a file.
+
+```javascript
+fstream
+  .Writer({ path: "path/to/symlink"
+          , linkpath: "./file"
+          , SymbolicLink: true
+          , mode: "0755" // octal strings supported
+          })
+  .end()
+```
+
+If isSymbolicLink is a function, it'll be called, and if it returns
+true, then it'll treat it as a symlink.  If it's not a function, then
+any truish value will make a symlink, or you can set `type:
+'SymbolicLink'`, which does the same thing.
+
+Note that the linkpath is relative to the symbolic link location, not
+the parent dir or cwd.
+
+```javascript
+fstream
+  .Reader("path/to/dir")
+  .pipe(fstream.Writer("path/to/other/dir"))
+```
+
+This will do like `cp -Rp path/to/dir path/to/other/dir`.  If the other
+dir exists and isn't a directory, then it'll emit an error.  It'll also
+set the uid, gid, mode, etc. to be identical.  In this way, it's more
+like `rsync -a` than simply a copy.

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, 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.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.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.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+## USAGE

+var inflight = require('inflight')
+
+// some request that does some stuff
+function req(key, callback) {
+  // key is any random string.  like a url or filename or whatever.
+  //
+  // will return either a falsey value, indicating that the
+  // request for this key is already in flight, or a new callback
+  // which when called will call all callbacks passed to inflightk
+  // with the same key
+  callback = inflight(key, callback)
+
+  // If we got a falsey value back, then there's already a req going
+  if (!callback) return
+
+  // this is where you'd fetch the url or whatever
+  // callback is also once()-ified, so it can safely be assigned
+  // to multiple events etc.  First call wins.
+  setTimeout(function() {
+    callback(null, key)
+  }, 100)
+}
+
+// only assigns a single setTimeout
+// when it dings, all cbs get called
+req('foo', cb1)
+req('foo', cb2)

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](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 instantiating 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.
+
+### 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.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.log(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' }
+```
+
+# security
+
+Previous versions had a prototype pollution bug that could cause privilege
+escalation in some circumstances when handling untrusted user input.
+
+Please use version 1.2.3 or later: https://snyk.io/vuln/SNYK-JS-MINIMIST-559764
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+
+  ```
+  > require('./')('one two three -- four five --six'.split(' '), { '--': true })
+  { _: [ 'one', 'two', 'three' ],
+    '--': [ 'four', 'five', '--six' ] }
+  ```
+
+  Note that with `opts['--']` set, parsing for arguments still stops after the
+  `--`.
+
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install minimist
+```

+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# 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.

+
+Execute a listener when a response is about to write headers.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install on-headers
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var onHeaders = require('on-headers')
+```
+
+### onHeaders(res, listener)
+
+This will add the listener `listener` to fire when headers are emitted for `res`.
+The listener is passed the `response` object as it's context (`this`). Headers are
+considered to be emitted only once, right before they are sent to the client.
+
+When this is called multiple times on the same `res`, the `listener`s are fired
+in the reverse order they were added.
+
+## Examples
+
+```js
+var http = require('http')
+var onHeaders = require('on-headers')
+
+http
+  .createServer(onRequest)
+  .listen(3000)
+
+function addPoweredBy () {
+  // set if not set by end of request
+  if (!this.getHeader('X-Powered-By')) {
+    this.setHeader('X-Powered-By', 'Node.js')
+  }
+}
+
+function onRequest (req, res) {
+  onHeaders(res, addPoweredBy)
+
+  res.setHeader('Content-Type', 'text/plain')
+  res.end('hello!')
+}
+```
+
+## Testing
+
+```sh
+$ npm test
+```

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).

+# unzipper
+
+This is an active fork and drop-in replacement of the [node-unzip](https://github.com/EvanOxfeld/node-unzip) and addresses the following issues:
+* finish/close events are not always triggered, particular when the input stream is slower than the receivers
+* Any files are buffered into memory before passing on to entry
+
+The structure of this fork is similar to the original, but uses Promises and inherit guarantees provided by node streams to ensure low memory footprint and emits finish/close events at the end of processing.   The new `Parser` will push any parsed `entries` downstream if you pipe from it, while still supporting the legacy `entry` event as well.
+
+Breaking changes: The new `Parser` will not automatically drain entries if there are no listeners or pipes in place.
+
+Unzipper provides simple APIs similar to [node-tar](https://github.com/isaacs/node-tar) for parsing and extracting zip files.
+There are no added compiled dependencies - inflation is handled by node.js's built in zlib support.
+
+Please note:  Methods that use the Central Directory instead of parsing entire file can be found under [`Open`](#open)
+
+Chrome extension files (.crx) are zipfiles with an [extra header](http://www.adambarth.com/experimental/crx/docs/crx.html) at the start of the file.  Unzipper will parse .crx file with the streaming methods (`Parse` and `ParseOne`).  The `Open` methods will check for `crx` headers and parse crx files, but only if you provide `crx: true` in options.
+
+## Installation
+
+```bash
+$ npm install unzipper
+```
+
+## Quick Examples
+
+### Extract to a directory
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Extract({ path: 'output/path' }));
+```
+
+Extract emits the 'close' event once the zip's contents have been fully extracted to disk. `Extract` uses [fstream.Writer](https://www.npmjs.com/package/fstream) and therefore needs need an absolute path to the destination directory.  This directory will be automatically created if it doesn't already exits.
+
+### Parse zip file contents
+
+Process each zip file entry or pipe entries to another stream.
+
+__Important__: If you do not intend to consume an entry stream's raw data, call autodrain() to dispose of the entry's
+contents. Otherwise the stream will halt.   `.autodrain()` returns an empty stream that provides `error` and `finish` events.
+Additionally you can call `.autodrain().promise()` to get the promisified version of success or failure of the autodrain.
+
+```js
+// If you want to handle autodrain errors you can either:
+entry.autodrain().catch(e => handleError);
+// or
+entry.autodrain().on('error' => handleError);
+```
+
+Here is a quick example:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .on('entry', function (entry) {
+    const fileName = entry.path;
+    const type = entry.type; // 'Directory' or 'File'
+    const size = entry.vars.uncompressedSize; // There is also compressedSize;
+    if (fileName === "this IS the file I'm looking for") {
+      entry.pipe(fs.createWriteStream('output/path'));
+    } else {
+      entry.autodrain();
+    }
+  });
+```
+
+and the same example using async iterators:
+
+```js
+const zip = fs.createReadStream('path/to/archive.zip').pipe(unzipper.Parse({forceStream: true}));
+for await (const entry of zip) {
+  const fileName = entry.path;
+  const type = entry.type; // 'Directory' or 'File'
+  const size = entry.vars.uncompressedSize; // There is also compressedSize;
+  if (fileName === "this IS the file I'm looking for") {
+    entry.pipe(fs.createWriteStream('output/path'));
+  } else {
+    entry.autodrain();
+  }
+}
+```
+
+### Parse zip by piping entries downstream
+
+If you `pipe` from unzipper the downstream components will receive each `entry` for further processing.   This allows for clean pipelines transforming zipfiles into unzipped data.
+
+Example using `stream.Transform`:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .pipe(stream.Transform({
+    objectMode: true,
+    transform: function(entry,e,cb) {
+      const fileName = entry.path;
+      const type = entry.type; // 'Directory' or 'File'
+      const size = entry.vars.uncompressedSize; // There is also compressedSize;
+      if (fileName === "this IS the file I'm looking for") {
+        entry.pipe(fs.createWriteStream('output/path'))
+          .on('finish',cb);
+      } else {
+        entry.autodrain();
+        cb();
+      }
+    }
+  }
+  }));
+```
+
+Example using [etl](https://www.npmjs.com/package/etl):
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .pipe(etl.map(entry => {
+    if (entry.path == "this IS the file I'm looking for")
+      return entry
+        .pipe(etl.toFile('output/path'))
+        .promise();
+    else
+      entry.autodrain();
+  }))
+
+```
+
+### Parse a single file and pipe contents
+
+`unzipper.parseOne([regex])` is a convenience method that unzips only one file from the archive and pipes the contents down (not the entry itself).  If no search criteria is specified, the first file in the archive will be unzipped.  Otherwise, each filename will be compared to the criteria and the first one to match will be unzipped and piped down.  If no file matches then the the stream will end without any content.
+
+Example:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.ParseOne())
+  .pipe(fs.createReadStream('firstFile.txt'));
+```
+
+### Buffering the content of an entry into memory
+
+While the recommended strategy of consuming the unzipped contents is using streams, it is sometimes convenient to be able to get the full buffered contents of each file .  Each `entry` provides a `.buffer` function that consumes the entry by buffering the contents into memory and returning a promise to the complete buffer.
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .pipe(etl.map(async entry => {
+    if (entry.path == "this IS the file I'm looking for") {
+      const content = await entry.buffer();
+      await fs.writeFile('output/path',content);
+    }
+    else {
+      entry.autodrain();
+    }
+  }))
+```
+
+### Parse.promise() syntax sugar
+
+The parser emits `finish` and `error` events like any other stream.  The parser additionally provides a promise wrapper around those two events to allow easy folding into existing Promise-based structures.
+
+Example:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .on('entry', entry => entry.autodrain())
+  .promise()
+  .then( () => console.log('done'), e => console.log('error',e));
+```
+
+### Parse zip created by DOS ZIP or Windows ZIP Folders
+
+Archives created by legacy tools usually have filenames encoded with IBM PC (Windows OEM) character set.
+You can decode filenames with preferred character set:
+
+```js
+const il = require('iconv-lite');
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .on('entry', function (entry) {
+    // if some legacy zip tool follow ZIP spec then this flag will be set
+    const isUnicode = entry.props.flags.isUnicode;
+    // decode "non-unicode" filename from OEM Cyrillic character set
+    const fileName = isUnicode ? entry.path : il.decode(entry.props.pathBuffer, 'cp866');
+    const type = entry.type; // 'Directory' or 'File'
+    const size = entry.vars.uncompressedSize; // There is also compressedSize;
+    if (fileName === "Текстовый файл.txt") {
+      entry.pipe(fs.createWriteStream(fileName));
+    } else {
+      entry.autodrain();
+    }
+  });
+```
+
+## Open
+Previous methods rely on the entire zipfile being received through a pipe.  The Open methods load take a different approach: load the central directory first (at the end of the zipfile) and provide the ability to pick and choose which zipfiles to extract, even extracting them in parallel.   The open methods return a promise on the contents of the directory, with individual `files` listed in an array.   Each file element has the following methods:
+* `stream([password])` - returns a stream of the unzipped content which can be piped to any destination
+* `buffer([password])` - returns a promise on the buffered content of the file)
+If the file is encrypted you will have to supply a password to decrypt, otherwise you can leave blank.
+Unlike `adm-zip` the Open methods will never read the entire zipfile into buffer.
+
+The last argument is optional `options` object where you can specify `tailSize` (default 80 bytes), i.e. how many bytes should we read at the end of the zipfile to locate the endOfCentralDirectory.  This location can be variable depending on zip64 extensible data sector size.   Additionally you can supply option `crx: true` which will check for a crx header and parse the file accordingly by shifting all file offsets by the length of the crx header.
+
+### Open.file([path], [options])
+Returns a Promise to the central directory information with methods to extract individual files.   `start` and `end` options are used to avoid reading the whole file.
+
+Example:
+```js
+async function main() {
+  const directory = await unzipper.Open.file('path/to/archive.zip');
+  console.log('directory', d);
+  return new Promise( (resolve, reject) => {
+    directory.files[0]
+      .stream()
+      .pipe(fs.createWriteStream('firstFile'))
+      .on('error',reject)
+      .on('finish',resolve)
+  });
+}
+
+main();
+```
+
+### Open.url([requestLibrary], [url | params], [options])
+This function will return a Promise to the central directory information from a URL point to a zipfile.  Range-headers are used to avoid reading the whole file. Unzipper does not ship with a request library so you will have to provide it as the first option.
+
+Live Example: (extracts a tiny xml file from the middle of a 500MB zipfile)
+
+```js
+const request = require('request');
+const unzipper = require('./unzip');
+
+async function main() {
+  const directory = await unzipper.Open.url(request,'http://www2.census.gov/geo/tiger/TIGER2015/ZCTA5/tl_2015_us_zcta510.zip');
+  const file = directory.files.find(d => d.path === 'tl_2015_us_zcta510.shp.iso.xml');
+  const content = await file.buffer();
+  console.log(content.toString());
+}
+
+main();
+```
+
+
+This function takes a second parameter which can either be a string containing the `url` to request, or an `options` object to invoke the supplied `request` library with. This can be used when other request options are required, such as custom headers or authentication to a third party service.
+
+```js
+const request = require('google-oauth-jwt').requestWithJWT();
+
+const googleStorageOptions = {
+  url: `https://www.googleapis.com/storage/v1/b/m-bucket-name/o/my-object-name`,
+  qs: { alt: 'media' },
+  jwt: {
+      email: google.storage.credentials.client_email,
+      key: google.storage.credentials.private_key,
+      scopes: ['https://www.googleapis.com/auth/devstorage.read_only']
+  }
+});
+
+async function getFile(req, res, next) {
+  const directory = await unzipper.Open.url(request, googleStorageOptions);
+  const file = zip.files.find((file) => file.path === 'my-filename');
+  return file.stream().pipe(res);
+});
+```
+
+### Open.s3([aws-sdk], [params], [options])
+This function will return a Promise to the central directory information from a zipfile on S3.  Range-headers are used to avoid reading the whole file.    Unzipper does not ship with with the aws-sdk so you have to provide an instantiated client as first arguments.    The params object requires `Bucket` and `Key` to fetch the correct file.
+
+Example:
+
+```js
+const unzipper = require('./unzip');
+const AWS = require('aws-sdk');
+const s3Client = AWS.S3(config);
+
+async function main() {
+  const directory = await unzipper.Open.s3(s3Client,{Bucket: 'unzipper', Key: 'archive.zip'});
+  return new Promise( (resolve, reject) => {
+    directory.files[0]
+      .stream()
+      .pipe(fs.createWriteStream('firstFile'))
+      .on('error',reject)
+      .on('finish',resolve)
+  });
+}
+
+main();
+```
+
+### Open.buffer(buffer, [options])
+If you already have the zip file in-memory as a buffer, you can open the contents directly.
+
+Example:
+
+```js
+// never use readFileSync - only used here to simplify the example
+const buffer = fs.readFileSync('path/to/arhive.zip');
+
+async function main() {
+  const directory = await unzipper.Open.buffer(buffer);
+  console.log('directory',directory);
+  // ...
+}
+
+main();
+```
+
+### Open.[method].extract()
+
+The directory object returned from `Open.[method]` provides an `extract` method which extracts all the files to a specified `path`, with an optional `concurrency` (default: 1).
+
+Example (with concurrency of 5):
+
+```js
+unzip.Open.file('path/to/archive.zip')
+  .then(d => d.extract({path: '/extraction/path', concurrency: 5}));
+```

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)

+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+

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

+***Node-core v8.9.4 string_decoder for userland***
+
+
+[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash
+npm install --save string_decoder
+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+util-deprecate
+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```
