-/**
- * ## Integration Testing
- *
- * Chai HTTP provides an interface for live integration
- * testing via [superagent](https://github.com/visionmedia/superagent).
- * To do this, you must first
- * construct a request to an application or url.
- *
- * Upon construction you are provided a chainable api that
- * allows you to specify the http VERB request (get, post, etc)
- * that you wish to invoke.
- *
- * #### Application / Server
- *
- * You may use a function (such as an express or connect app)
- * or a node.js http(s) server as the foundation for your request.
- * If the server is not running, chai-http will find a suitable
- * port to listen on for a given test.
- *
- * __Note:__ This feature is only supported on Node.js, not in web browsers.
- *
- * ```js
- * chai.request(app)
- *   .get('/')
- * ```
- *
- * #### URL
- *
- * You may also use a base url as the foundation of your request.
- *
- * ```js
- * chai.request('http://localhost:8080')
- *   .get('/')
- * ```
- *
- * #### Setting up requests
- *
- * Once a request is created with a given VERB, it can have headers, form data,
- * json, or even file attachments added to it, all with a simple API:
- *
- * ```js
- * // Send some JSON
- * chai.request(app)
- *   .put('/user/me')
- *   .set('X-API-Key', 'foobar')
- *   .send({ password: '123', confirmPassword: '123' })
- * ```
- *
- * ```js
- * // Send some Form Data
- * chai.request(app)
- *   .post('/user/me')
- *   .field('_method', 'put')
- *   .field('password', '123')
- *   .field('confirmPassword', '123')
- * ```
- *
- * ```js
- * // Attach a file
- * chai.request(app)
- *   .post('/user/avatar')
- *   .attach('imageField', fs.readFileSync('avatar.png'), 'avatar.png')
- * ```
- *
- * ```js
- * // Authenticate with Basic authentication
- * chai.request(app)
- *   .get('/protected')
- *   .auth('user', 'pass')
- * ```
- *
- * ```js
- * // Chain some GET query parameters
- * chai.request(app)
- *   .get('/search')
- *   .query({name: 'foo', limit: 10}) // /search?name=foo&limit=10
- * ```
- *
- * #### Dealing with the response - traditional
- *
- * To make the request and assert on its response, the `end` method can be used:
- *
- * ```js
- * chai.request(app)
- *   .put('/user/me')
- *   .send({ password: '123', confirmPassword: '123' })
- *   .end(function (err, res) {
- *      expect(err).to.be.null;
- *      expect(res).to.have.status(200);
- *   });
- * ```
- * ##### Caveat
- * Because the `end` function is passed a callback, assertions are run
- * asynchronously. Therefore, a mechanism must be used to notify the testing
- * framework that the callback has completed. Otherwise, the test will pass before
- * the assertions are checked.
- *
- * For example, in the [Mocha test framework](http://mochajs.org/), this is
- * accomplished using the
- * [`done` callback](https://mochajs.org/#asynchronous-code), which signal that the
- * callback has completed, and the assertions can be verified:
- *
- * ```js
- * it('fails, as expected', function(done) { // <= Pass in done callback
- *   chai.request('http://localhost:8080')
- *   .get('/')
- *   .end(function(err, res) {
- *     expect(res).to.have.status(123);
- *     done();                               // <= Call done to signal callback end
- *   });
- * }) ;
- *
- * it('succeeds silently!', function() {   // <= No done callback
- *   chai.request('http://localhost:8080')
- *   .get('/')
- *   .end(function(err, res) {
- *     expect(res).to.have.status(123);    // <= Test completes before this runs
- *   });
- * }) ;
- * ```
- *
- * When `done` is passed in, Mocha will wait until the call to `done()`, or until
- * the [timeout](http://mochajs.org/#timeouts) expires. `done` also accepts an
- * error parameter when signaling completion.
- *
- * #### Dealing with the response - Promises
- *
- * If `Promise` is available, `request()` becomes a Promise capable library -
- * and chaining of `then`s becomes possible:
- *
- * ```js
- * chai.request(app)
- *   .put('/user/me')
- *   .send({ password: '123', confirmPassword: '123' })
- *   .then(function (res) {
- *      expect(res).to.have.status(200);
- *   })
- *   .catch(function (err) {
- *      throw err;
- *   })
- * ```
- *
- * __Note:__ Node.js version 0.10.x and some older web browsers do not have
- * native promise support. You can use any promise library, such as
- * [es6-promise](https://github.com/jakearchibald/es6-promise) or
- * [kriskowal/q](https://github.com/kriskowal/q) and call the `addPromise`
- * method to use that library with Chai HTTP. For example:
- *
- * ```js
- * var chai = require('chai');
- * chai.use(require('chai-http'));
- *
- * // Add promise support if this does not exist natively.
- * if (!global.Promise) {
- *   var q = require('q');
- *   chai.request.addPromises(q.Promise);
- * }
- * ```
- *
- * #### Retaining cookies with each request
- *
- * Sometimes you need to keep cookies from one request, and send them with the
- * next. For this, `.request.agent()` is available:
- *
- * ```js
- * // Log in
- * var agent = chai.request.agent(app)
- * agent

-/**
- * ## Integration Testing
- *
- * Chai HTTP provides an interface for live integration
- * testing via [superagent](https://github.com/visionmedia/superagent).
- * To do this, you must first
- * construct a request to an application or url.
- *
- * Upon construction you are provided a chainable api that
- * allows you to specify the http VERB request (get, post, etc)
- * that you wish to invoke.
- *
- * #### Application / Server
- *
- * You may use a function (such as an express or connect app)
- * or a node.js http(s) server as the foundation for your request.
- * If the server is not running, chai-http will find a suitable
- * port to listen on for a given test.
- *
- * __Note:__ This feature is only supported on Node.js, not in web browsers.
- *
- * ```js
- * chai.request(app)
- *   .get('/')
- * ```
- *
- * #### URL
- *
- * You may also use a base url as the foundation of your request.
- *
- * ```js
- * chai.request('http://localhost:8080')
- *   .get('/')
- * ```
- *
- * #### Setting up requests
- *
- * Once a request is created with a given VERB, it can have headers, form data,
- * json, or even file attachments added to it, all with a simple API:
- *
- * ```js
- * // Send some JSON
- * chai.request(app)
- *   .put('/user/me')
- *   .set('X-API-Key', 'foobar')
- *   .send({ password: '123', confirmPassword: '123' })
- * ```
- *
- * ```js
- * // Send some Form Data
- * chai.request(app)
- *   .post('/user/me')
- *   .field('_method', 'put')
- *   .field('password', '123')
- *   .field('confirmPassword', '123')
- * ```
- *
- * ```js
- * // Attach a file
- * chai.request(app)
- *   .post('/user/avatar')
- *   .attach('imageField', fs.readFileSync('avatar.png'), 'avatar.png')
- * ```
- *
- * ```js
- * // Authenticate with Basic authentication
- * chai.request(app)
- *   .get('/protected')
- *   .auth('user', 'pass')
- * ```
- *
- * ```js
- * // Chain some GET query parameters
- * chai.request(app)
- *   .get('/search')
- *   .query({name: 'foo', limit: 10}) // /search?name=foo&limit=10
- * ```
- *
- * #### Dealing with the response - traditional
- *
- * To make the request and assert on its response, the `end` method can be used:
- *
- * ```js
- * chai.request(app)
- *   .put('/user/me')
- *   .send({ password: '123', confirmPassword: '123' })
- *   .end(function (err, res) {
- *      expect(err).to.be.null;
- *      expect(res).to.have.status(200);
- *   });
- * ```
- * ##### Caveat
- * Because the `end` function is passed a callback, assertions are run
- * asynchronously. Therefore, a mechanism must be used to notify the testing
- * framework that the callback has completed. Otherwise, the test will pass before
- * the assertions are checked.
- *
- * For example, in the [Mocha test framework](http://mochajs.org/), this is
- * accomplished using the
- * [`done` callback](https://mochajs.org/#asynchronous-code), which signal that the
- * callback has completed, and the assertions can be verified:
- *
- * ```js
- * it('fails, as expected', function(done) { // <= Pass in done callback
- *   chai.request('http://localhost:8080')
- *   .get('/')
- *   .end(function(err, res) {
- *     expect(res).to.have.status(123);
- *     done();                               // <= Call done to signal callback end
- *   });
- * }) ;
- *
- * it('succeeds silently!', function() {   // <= No done callback
- *   chai.request('http://localhost:8080')
- *   .get('/')
- *   .end(function(err, res) {
- *     expect(res).to.have.status(123);    // <= Test completes before this runs
- *   });
- * }) ;
- * ```
- *
- * When `done` is passed in, Mocha will wait until the call to `done()`, or until
- * the [timeout](http://mochajs.org/#timeouts) expires. `done` also accepts an
- * error parameter when signaling completion.
- *
- * #### Dealing with the response - Promises
- *
- * If `Promise` is available, `request()` becomes a Promise capable library -
- * and chaining of `then`s becomes possible:
- *
- * ```js
- * chai.request(app)
- *   .put('/user/me')
- *   .send({ password: '123', confirmPassword: '123' })
- *   .then(function (res) {
- *      expect(res).to.have.status(200);
- *   })
- *   .catch(function (err) {
- *      throw err;
- *   })
- * ```
- *
- * __Note:__ Node.js version 0.10.x and some older web browsers do not have
- * native promise support. You can use any promise library, such as
- * [es6-promise](https://github.com/jakearchibald/es6-promise) or
- * [kriskowal/q](https://github.com/kriskowal/q) and call the `addPromise`
- * method to use that library with Chai HTTP. For example:
- *
- * ```js
- * var chai = require('chai');
- * chai.use(require('chai-http'));
- *
- * // Add promise support if this does not exist natively.
- * if (!global.Promise) {
- *   var q = require('q');
- *   chai.request.addPromises(q.Promise);
- * }
- * ```
- *
- * #### Retaining cookies with each request
- *
- * Sometimes you need to keep cookies from one request, and send them with the
- * next. For this, `.request.agent()` is available:
- *
- * ```js
- * // Log in
- * var agent = chai.request.agent(app)
- * agent
- *   .post('/session')
- *   .send({ username: 'me', password: '123' })
- *   .then(function (res) {
- *     expect(res).to.have.cookie('sessionid');
- *     // The `agent` now has the sessionid cookie saved, and will send it
- *     // back to the server in the next request:
- *     return agent.get('/user/me')
- *       .then(function (res) {
- *          expect(res).to.have.status(200);
- *       })
- *   })
- * ```

-#CookieJar
-
-Simple robust cookie library
-
-##Exports
-
-###CookieAccessInfo(domain,path,secure,script)
-
-    class to determine matching qualities of a cookie
-
-#####Properties
-
-* String domain - domain to match
-* String path - path to match
-* Boolean secure - access is secure (ssl generally)
-* Boolean script - access is from a script
-
-
-###Cookie(cookiestr_or_cookie, request_domain, request_path)
-
-    turns input into a Cookie (singleton if given a Cookie)
-    the `request_domain` argument is used to default the domain if it is not explicit in the cookie string 
-    the `request_path` argument is used to set the path if it is not explicit in a cookie String.
-
-    explicit domains/paths will cascade, implied domains/paths must *exactly* match (see http://en.wikipedia.org/wiki/HTTP_cookie#Domain_and_Pat)
-
-#####Properties
-
-* String name - name of the cookie
-* String value - string associated with the cookie
-* String domain - domain to match (on a cookie a '.' at the start means a wildcard matching anything ending in the rest)
-* Boolean explicit_domain - if the domain was explicitly set via the cookie string
-* String path - base path to match (matches any path starting with this '/' is root)
-* Boolean explicit_path - if the path was explicitly set via the cookie string
-* Boolean noscript - if it should be kept from scripts
-* Boolean secure - should it only be transmitted over secure means
-* Number expiration_date - number of millis since 1970 at which this should be removed
-
-#####Methods
-
-* String toString() - the __set-cookie:__ string for this cookie
-* String toValueString() - the __cookie:__ string for this cookie
-* Cookie parse(cookiestr, request_domain, request_path) - parses the string onto this cookie or a new one if called directly
-* Boolean matches(access_info) - returns true if the access_info allows retrieval of this cookie
-* Boolean collidesWith(cookie) - returns true if the cookies cannot exist in the same space (domain and path match)
-
-
-###CookieJar()
-
-    class to hold numerous cookies from multiple domains correctly
-
-#####Methods

-ipRegex({exact: true}).test('unicorn 192.168.0.1');
-//=> false
-
-ipRegex.v6({exact: true}).test('1:2:3:4:5:6:7:8');
-//=> true
-
-'unicorn 192.168.0.1 cake 1:2:3:4:5:6:7:8 rainbow'.match(ipRegex());

-HTTP verbs that Node.js core's HTTP parser supports.
-
-This module provides an export that is just like `http.METHODS` from Node.js core,
-with the following differences:
-
-  * All method names are lower-cased.
-  * Contains a fallback list of methods for Node.js versions that do not have a
-    `http.METHODS` export (0.10 and lower).
-  * Provides the fallback list when using tools like `browserify` without pulling
-    in the `http` shim module.
-
-## Install
-
-```bash
-$ npm install methods
-```
-
-## API
-
-```js
-var methods = require('methods')
-```
-
-### methods
-
-This is an array of lower-cased method names that Node.js supports. If Node.js
-provides the `http.METHODS` export, then this is the same array lower-cased,
-otherwise it is a snapshot of the verbs from Node.js 0.10.

-# qs
-
-A querystring parsing and stringifying library with some added security.
-
-[![Build Status](https://api.travis-ci.org/ljharb/qs.svg)](http://travis-ci.org/ljharb/qs)
-
-Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
-
-The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
-
-## Usage
-
-```javascript
-var qs = require('qs');
-var assert = require('assert');
-
-var obj = qs.parse('a=c');
-assert.deepEqual(obj, { a: 'c' });
-
-var str = qs.stringify(obj);
-assert.equal(str, 'a=c');
-```
-
-### Parsing Objects
-
-[](#preventEval)
-```javascript
-qs.parse(string, [options]);
-```
-
-**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
-For example, the string `'foo[bar]=baz'` converts to:
-
-```javascript
-assert.deepEqual(qs.parse('foo[bar]=baz'), {
-  foo: {
-    bar: 'baz'
-  }
-});
-```
-
-When using the `plainObjects` option the parsed value is returned as a plain object, created via `Object.create(null)` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
-
-```javascript
-var plainObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
-assert.deepEqual(plainObject, { a: { hasOwnProperty: 'b' } });
-```
-
-By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties. *WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten. Always be careful with this option.
-
-```javascript
-var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
-assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
-```
-
-URI encoded strings work too:
-
-```javascript
-assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
-  a: { b: 'c' }
-});
-```
-
-You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
-
-```javascript
-assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
-  foo: {
-    bar: {
-      baz: 'foobarbaz'
-    }
-  }
-});
-```
-
-By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
-`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
-
-```javascript
-var expected = {
-  a: {
-    b: {
-      c: {
-        d: {
-          e: {
-            f: {
-              '[g][h][i]': 'j'
-            }
-          }
-        }
-      }
-    }
-  }
-};
-var string = 'a[b][c][d][e][f][g][h][i]=j';
-assert.deepEqual(qs.parse(string), expected);
-```
-
-This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
-
-```javascript
-var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
-assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
-```
-
-The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
-
-For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
-
-```javascript
-var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
-assert.deepEqual(limited, { a: 'b' });
-```
-
-An optional delimiter can also be passed:
-
-```javascript
-var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
-assert.deepEqual(delimited, { a: 'b', c: 'd' });
-```
-
-Delimiters can be a regular expression too:
-
-```javascript
-var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
-assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
-```
-
-Option `allowDots` can be used to enable dot notation:
-
-```javascript
-var withDots = qs.parse('a.b=c', { allowDots: true });
-assert.deepEqual(withDots, { a: { b: 'c' } });
-```
-
-### Parsing Arrays
-
-**qs** can also parse arrays using a similar `[]` notation:
-
-```javascript
-var withArray = qs.parse('a[]=b&a[]=c');
-assert.deepEqual(withArray, { a: ['b', 'c'] });
-```
-
-You may specify an index as well:
-
-```javascript
-var withIndexes = qs.parse('a[1]=c&a[0]=b');
-assert.deepEqual(withIndexes, { a: ['b', 'c'] });
-```
-
-Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
-to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
-their order:
-
-```javascript
-var noSparse = qs.parse('a[1]=b&a[15]=c');
-assert.deepEqual(noSparse, { a: ['b', 'c'] });
-```
-
-Note that an empty string is also a value, and will be preserved:
-
-```javascript
-var withEmptyString = qs.parse('a[]=&a[]=b');
-assert.deepEqual(withEmptyString, { a: ['', 'b'] });
-
-var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
-assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
-```
-
-**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
-instead be converted to an object with the index as the key:
-
-```javascript
-var withMaxIndex = qs.parse('a[100]=b');
-assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
-```
-
-This limit can be overridden by passing an `arrayLimit` option:
-
-```javascript
-var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
-assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
-```
-
-To disable array parsing entirely, set `parseArrays` to `false`.
-
-```javascript
-var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
-assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
-```
-
-If you mix notations, **qs** will merge the two items into an object:
-
-```javascript
-var mixedNotation = qs.parse('a[0]=b&a[b]=c');
-assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
-```
-
-You can also create arrays of objects:
-
-```javascript
-var arraysOfObjects = qs.parse('a[][b]=c');
-assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
-```
-
-### Stringifying
-
-[](#preventEval)
-```javascript
-qs.stringify(object, [options]);
-```
-
-When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b' }), 'a=b');
-assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
-```
-
-This encoding can be disabled by setting the `encode` option to `false`:
-
-```javascript
-var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
-assert.equal(unencoded, 'a[b]=c');
-```
-
-This encoding can also be replaced by a custom encoding method set as `encoder` option:
-
-```javascript
-var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
-  // Passed in values `a`, `b`, `c`
-  return // Return encoded string
-}})
-```
-
-_(Note: the `encoder` option does not apply if `encode` is `false`)_
-
-Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
-
-```javascript
-var decoded = qs.parse('x=z', { decoder: function (str) {
-  // Passed in values `x`, `z`
-  return // Return decoded string
-}})
-```
-
-Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
-
-When arrays are stringified, by default they are given explicit indices:
-
-```javascript
-qs.stringify({ a: ['b', 'c', 'd'] });
-// 'a[0]=b&a[1]=c&a[2]=d'
-```
-
-You may override this by setting the `indices` option to `false`:
-
-```javascript
-qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
-// 'a=b&a=c&a=d'
-```
-
-You may use the `arrayFormat` option to specify the format of the output array
-
-```javascript
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
-// 'a[0]=b&a[1]=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
-// 'a[]=b&a[]=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
-// 'a=b&a=c'
-```
-
-Empty strings and null values will omit the value, but the equals sign (=) remains in place:
-
-```javascript
-assert.equal(qs.stringify({ a: '' }), 'a=');
-```
-
-Properties that are set to `undefined` will be omitted entirely:
-
-```javascript
-assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
-```
-
-The delimiter may be overridden with stringify as well:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
-```
-
-Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
-If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you
-pass an array, it will be used to select properties and array indices for stringification:
-
-```javascript
-function filterFunc(prefix, value) {
-  if (prefix == 'b') {
-    // Return an `undefined` value to omit a property.
-    return;
-  }
-  if (prefix == 'e[f]') {
-    return value.getTime();
-  }
-  if (prefix == 'e[g][0]') {
-    return value * 2;
-  }
-  return value;
-}
-qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
-// 'a=b&c=d&e[f]=123&e[g][0]=4'
-qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
-// 'a=b&e=f'
-qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
-// 'a[0]=b&a[2]=d'
-```
-
-### Handling of `null` values
-
-By default, `null` values are treated like empty strings:
-
-```javascript
-var withNull = qs.stringify({ a: null, b: '' });
-assert.equal(withNull, 'a=&b=');
-```
-
-Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings.
-
-```javascript
-var equalsInsensitive = qs.parse('a&b=');
-assert.deepEqual(equalsInsensitive, { a: '', b: '' });
-```
-
-To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
-values have no `=` sign:
-
-```javascript
-var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
-assert.equal(strictNull, 'a&b=');
-```
-
-To parse values without `=` back to `null` use the `strictNullHandling` flag:
-
-```javascript
-var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
-assert.deepEqual(parsedStrictNull, { a: null, b: '' });
-```
-
-To completely skip rendering keys with `null` values, use the `skipNulls` flag:
-
-```javascript
-var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
-assert.equal(nullsSkipped, 'a=b');
-```
-
-### Dealing with special character sets
-
-By default the encoding and decoding of characters is done in `utf-8`. If you 
-wish to encode querystrings to a different character set (i.e.
-[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
-[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
-
-```javascript
-var encoder = require('qs-iconv/encoder')('shift_jis');
-var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
-assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
-```
-
-This also works for decoding of query strings:
-
-```javascript
-var decoder = require('qs-iconv/decoder')('shift_jis');
-var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
-assert.deepEqual(obj, { a: 'こんにちは！' });
-```

-# 2.1.0
-
- * Refactored async parsers. Now the `end` callback waits for async parsers to finish (Kornel Lesiński)
- * Errors thrown in `.end()` callback don't cause the callback to be called twice (Kornel Lesiński)
- * Added `headers` to `toJSON()` (Tao)
-
-# 2.0.0
-
-## Breaking changes
-
-Breaking changes are in rarely used functionality, so we hope upgrade will be smooth for most users.
-
-  * Browser: The `.parse()` method has been renamed to `.serialize()` for consistency with NodeJS version.
-  * Browser: Query string keys without a value used to be parsed as `'undefined'`, now their value is `''` (empty string) (shura, Kornel Lesiński).
-  * NodeJS: The `redirect` event is called after new query string and headers have been set and is allowed to override the request URL (Kornel Lesiński)
-  * `.then()` returns a real `Promise`. Note that use of superagent with promises now requires a global `Promise` object.
-    If you target Internet Explorer or Node 0.10, you'll need `require('es6-promise').polyfill()` or similar.
-  * Upgraded all dependencies (Peter Lyons)
-  * Renamed properties documented as `@api private` to have `_prefixed` names (Kornel Lesiński)

-# SuperAgent
-
-SuperAgent is a small progressive __client-side__ HTTP request library, and __Node.js__ module with the same API, sporting many high-level HTTP client features. View the [docs](http://visionmedia.github.io/superagent/).
-
-![super agent](http://f.cl.ly/items/3d282n3A0h0Z0K2w0q2a/Screenshot.png)
-
-## Installation
-
-node:
-
-```
-$ npm install superagent
-```
-
-component:
-
-```
-$ component install visionmedia/superagent
-```
-
-Works with [browserify](https://github.com/substack/node-browserify) and should work with [webpack](https://github.com/visionmedia/superagent/wiki/Superagent-for-Webpack)
-
-```js
-request
-  .post('/api/pet')
-  .send({ name: 'Manny', species: 'cat' })
-  .set('X-API-Key', 'foobar')
-  .set('Accept', 'application/json')
-  .end(function(err, res){
-    // Calling the end function will send the request
-  });
-```
-
-## Supported browsers
-
-Tested browsers:
-
-- Latest Android
-- Latest Firefox
-- Latest Chrome
-- IE10 through latest. IE9 with polyfills.
-- Latest iPhone
-- Latest Safari
-
-Even though IE9 is supported, a polyfill for `window.FormData` is required for `.field()`, and `window.btoa` is needed to use basic auth.
-
-# Plugins
-
-Superagent is easily extended via plugins.
-
-```js
-var nocache = require('superagent-no-cache');
-var request = require('superagent');
-var prefix = require('superagent-prefix')('/static');
-
-request
-.get('/some-url')
-.use(prefix) // Prefixes *only* this request
-.use(nocache) // Prevents caching of *only* this request
-.end(function(err, res){
-    // Do something
-});
-```
-
-Existing plugins:
- * [superagent-no-cache](https://github.com/johntron/superagent-no-cache) - prevents caching by including Cache-Control header

- * [superagent-mocker](https://github.com/shuvalov-anton/superagent-mocker) — simulate REST API
- * [superagent-cache](https://github.com/jpodwys/superagent-cache) - superagent with built-in, flexible caching
- * [superagent-jsonapify](https://github.com/alex94puchades/superagent-jsonapify) - A lightweight [json-api](http://jsonapi.org/format/) client addon for superagent
- * [superagent-serializer](https://github.com/zzarcon/superagent-serializer) - Converts server payload into different cases
- * [superagent-promise-plugin](https://github.com/jomaxx/superagent-promise-plugin) - Shims req.end to return a promise when executed with no callback.
- * [superagent-use](https://github.com/koenpunt/superagent-use) - A client addon to apply plugins to all requests.
- * [superagent-httpbackend](https://www.npmjs.com/package/superagent-httpbackend) - stub out requests using AngularJS' $httpBackend syntax
- * [superagent-throttle](https://github.com/leviwheatcroft/superagent-throttle) - queues and intelligently throttles requests
- * [superagent-charset](https://github.com/magicdawn/superagent-charset) - add charset support for node's superagent
-
-Please prefix your plugin with `superagent-*` so that it can easily be found by others.

-## Packaging Notes for Developers
-
-**npm (for node)** is configured via the `package.json` file and the `.npmignore` file. Key metadata in the `package.json` file is the `version` field which should be changed according to semantic versioning and have a 1-1 correspondence with git tags. So for example, if you were to `git show v1.5.0:package.json | grep version`, you should see `"version": "1.5.0",` and this should hold true for every release. This can be handled via the `npm version` command. Be aware that when publishing, npm will presume the version being published should also be tagged in npm as `latest`, which is OK for normal incremental releases. For betas and minor/patch releases to older versions, be sure to include `--tag` appropriately to avoid an older release getting tagged as `latest`.
-
-**npm (for browser standalone)** When we publish versions to npm, we run `make superagent.js` which generates the standalone `superagent.js` file via `browserify`, and this file is included in the package published to npm (but this file is never checked into the git repository). If users want to install via npm but serve a single `.js` file directly to the browser, the `node_modules/superagent/superagent.js` is a standalone browserified file ready to go for that purpose. It is not minified.
-
-**npm (for browserify)** is handled via the `package.json` `browser` field which allows users to install superagent via npm, reference it from their browser code with `require('superagent')`, and then build their own application bundle via `browserify`, which will use `lib/client.js` as the superagent entrypoint.
-
-**bower** is configured via the `bower.json` file. Bower installs files directly from git/github without any transformation.
-
-**component** is configured via the `component.json` file.

-# SuperAgent
-
- Super Agent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs. It also works with Node.js!
-
-     request
-       .post('/api/pet')
-       .send({ name: 'Manny', species: 'cat' })
-       .set('X-API-Key', 'foobar')
-       .set('Accept', 'application/json')
-       .end(function(err, res){
-         if (err || !res.ok) {
-           alert('Oh no! error');
-         } else {
-           alert('yay got ' + JSON.stringify(res.body));
-         }
-       });
-
-## Test documentation
-
-  The following [test documentation](docs/test.html) was generated with [Mocha's](http://mochajs.org/) "doc" reporter, and directly reflects the test suite. This provides an additional source of documentation.
-
-## Request basics
-
- A request can be initiated by invoking the appropriate method on the `request` object, then calling `.end()` to send the request. For example a simple GET request:
-
-     request
-       .get('/search')
-       .end(function(err, res){
-
-       });
-
-  A method string may also be passed:
-
-    request('GET', '/search').end(callback);
-
-ES6 promises are supported. Instead of `.end()` you can call `.then()`:
-
-    request('GET', '/search').then(success, failure);
-
- The __node__ client may also provide absolute urls:
-
-     request
-       .get('http://example.com/search')
-       .end(function(err, res){
-
-       });
-
-  __DELETE__, __HEAD__, __POST__, __PUT__ and other __HTTP__ verbs may also be used, simply change the method name:
-
-    request
-      .head('/favicon.ico')
-      .end(function(err, res){
-
-      });
-
-  __DELETE__ is a special-case, as it's a reserved word, so the method is named `.del()`:
-
-    request
-      .del('/user/1')
-      .end(function(err, res){
-
-      });
-
-  The HTTP method defaults to __GET__, so if you wish, the following is valid:
-
-     request('/search', function(err, res){
-
-     });
-
-## Setting header fields
-
-  Setting header fields is simple, invoke `.set()` with a field name and value:
-
-     request
-       .get('/search')
-       .set('API-Key', 'foobar')
-       .set('Accept', 'application/json')
-       .end(callback);
-
-  You may also pass an object to set several fields in a single call:
-
-     request
-       .get('/search')
-       .set({ 'API-Key': 'foobar', Accept: 'application/json' })
-       .end(callback);
-
-## GET requests
-
- The `.query()` method accepts objects, which when used with the __GET__ method will form a query-string. The following will produce the path `/search?query=Manny&range=1..5&order=desc`.
-
-     request
-       .get('/search')
-       .query({ query: 'Manny' })
-       .query({ range: '1..5' })
-       .query({ order: 'desc' })
-       .end(function(err, res){
-
-       });
-
-  Or as a single object:
-
-    request
-      .get('/search')
-      .query({ query: 'Manny', range: '1..5', order: 'desc' })
-      .end(function(err, res){
-
-      });
-
-  The `.query()` method accepts strings as well:
-
-      request
-        .get('/querystring')
-        .query('search=Manny&range=1..5')
-        .end(function(err, res){
-
-        });
-
-  Or joined:
-
-      request
-        .get('/querystring')
-        .query('search=Manny')
-        .query('range=1..5')
-        .end(function(err, res){
-
-        });
-
-## HEAD requests
-
-You can also use the `.query()` method for HEAD requests. The following will produce the path `/users?email=joe@smith.com`.
-
-      request
-        .head('/users')
-        .query({ email: 'joe@smith.com' })
-        .end(function(err, res){
-
-        });
-
-## POST / PUT requests
-
-  A typical JSON __POST__ request might look a little like the following, where we set the Content-Type header field appropriately, and "write" some data, in this case just a JSON string.
-
-      request.post('/user')
-        .set('Content-Type', 'application/json')
-        .send('{"name":"tj","pet":"tobi"}')
-        .end(callback)
-
-  Since JSON is undoubtably the most common, it's the _default_! The following example is equivalent to the previous.
-
-      request.post('/user')
-        .send({ name: 'tj', pet: 'tobi' })
-        .end(callback)
-
-  Or using multiple `.send()` calls:
-
-      request.post('/user')
-        .send({ name: 'tj' })
-        .send({ pet: 'tobi' })
-        .end(callback)
-
-  By default sending strings will set the Content-Type to `application/x-www-form-urlencoded`,
-  multiple calls will be concatenated with `&`, here resulting in `name=tj&pet=tobi`:
-
-      request.post('/user')
-        .send('name=tj')
-        .send('pet=tobi')
-        .end(callback);
-
-  SuperAgent formats are extensible, however by default "json" and "form" are supported. To send the data as `application/x-www-form-urlencoded` simply invoke `.type()` with "form", where the default is "json". This request will POST the body "name=tj&pet=tobi".
-
-      request.post('/user')
-        .type('form')
-        .send({ name: 'tj' })
-        .send({ pet: 'tobi' })
-        .end(callback)
-
- Note: "form" is aliased as "form-data" and "urlencoded" for backwards compat.
-
-## Setting the Content-Type
-
-  The obvious solution is to use the `.set()` method:
-
-     request.post('/user')
-       .set('Content-Type', 'application/json')
-
-  As a short-hand the `.type()` method is also available, accepting
-  the canonicalized MIME type name complete with type/subtype, or
-  simply the extension name such as "xml", "json", "png", etc:
-
-     request.post('/user')
-       .type('application/json')
-
-     request.post('/user')
-       .type('json')
-
-     request.post('/user')
-       .type('png')
-
-## Serializing request body
-
-Superagent will automatically serialize JSON and forms. If you want to send the payload in a custom format, you can replace the built-in serialization with `.serialize()` method.
-
-## Setting Accept
-
-In a similar fashion to the `.type()` method it is also possible to set the Accept header via the short hand method `.accept()`. Which references `request.types` as well allowing you to specify either the full canonicalized MIME type name as type/subtype, or the extension suffix form as "xml", "json", "png", etc for convenience:
-
-     request.get('/user')
-       .accept('application/json')
-
-     request.get('/user')
-       .accept('json')
-
-     request.post('/user')
-       .accept('png')
-
-## Query strings
-
-  `res.query(obj)` is a method which may be used to build up a query-string. For example populating `?format=json&dest=/login` on a __POST__:
-
-    request
-      .post('/')
-      .query({ format: 'json' })
-      .query({ dest: '/login' })
-      .send({ post: 'data', here: 'wahoo' })
-      .end(callback);
-
-## Parsing response bodies
-
-  Super Agent will parse known response-body data for you, currently supporting `application/x-www-form-urlencoded`, `application/json`, and `multipart/form-data`.
-
-  You can set a custom parser (that takes precedence over built-in parsers) with the `.buffer(true).parse(fn)` method. If response buffering is not enabled (`.buffer(false)`) then the `response` event will be emitted without waiting for the body parser to finish, so `response.body` won't be available.
-
-### JSON / Urlencoded
-
-  The property `res.body` is the parsed object, for example if a request responded with the JSON string '{"user":{"name":"tobi"}}', `res.body.user.name` would be "tobi". Likewise the x-www-form-urlencoded value of "user[name]=tobi" would yield the same result.
-
-### Multipart
-
-  The Node client supports _multipart/form-data_ via the [Formidable](https://github.com/felixge/node-formidable) module. When parsing multipart responses, the object `res.files` is also available to you. Suppose for example a request responds with the following multipart body:
-
-    --whoop
-    Content-Disposition: attachment; name="image"; filename="tobi.png"
-    Content-Type: image/png
-
-    ... data here ...
-    --whoop
-    Content-Disposition: form-data; name="name"
-    Content-Type: text/plain
-
-    Tobi
-    --whoop--
-
-  You would have the values `res.body.name` provided as "Tobi", and `res.files.image` as a `File` object containing the path on disk, filename, and other properties.
-
-## Response properties
-
-  Many helpful flags and properties are set on the `Response` object, ranging from the response text, parsed response body, header fields, status flags and more.
-
-### Response text
-
-  The `res.text` property contains the unparsed response body string. This
-  property is always present for the client API, and only when the mime type
-  matches "text/*", "*/json", or "x-www-form-urlencoded" by default for node. The
-  reasoning is to conserve memory, as buffering text of large bodies such as multipart files or images is extremely inefficient.
-
-  To force buffering see the "Buffering responses" section.
-
-### Response body
-
-  Much like SuperAgent can auto-serialize request data, it can also automatically parse it. When a parser is defined for the Content-Type, it is parsed, which by default includes "application/json" and "application/x-www-form-urlencoded". The parsed object is then available via `res.body`.
-
-### Response header fields
-
-  The `res.header` contains an object of parsed header fields, lowercasing field names much like node does. For example `res.header['content-length']`.
-
-### Response Content-Type
-
-  The Content-Type response header is special-cased, providing `res.type`, which is void of the charset (if any). For example the Content-Type of "text/html; charset=utf8" will provide "text/html" as `res.type`, and the `res.charset` property would then contain "utf8".
-
-### Response status
-
-  The response status flags help determine if the request was a success, among other useful information, making SuperAgent ideal for interacting with RESTful web services. These flags are currently defined as:
-
-     var type = status / 100 | 0;
-
-     // status / class
-     res.status = status;
-     res.statusType = type;
-
-     // basics
-     res.info = 1 == type;
-     res.ok = 2 == type;
-     res.clientError = 4 == type;
-     res.serverError = 5 == type;
-     res.error = 4 == type || 5 == type;
-
-     // sugar
-     res.accepted = 202 == status;
-     res.noContent = 204 == status || 1223 == status;
-     res.badRequest = 400 == status;
-     res.unauthorized = 401 == status;
-     res.notAcceptable = 406 == status;
-     res.notFound = 404 == status;
-     res.forbidden = 403 == status;
-
-## Aborting requests
-
-  To abort requests simply invoke the `req.abort()` method.
-
-## Request timeouts
-
-  A timeout can be applied by invoking `req.timeout(ms)`, after which an error
-  will be triggered. To differentiate between other errors the `err.timeout` property
-  is set to the `ms` value. __NOTE__ that this is a timeout applied to the request
-  and all subsequent redirects, not per request.
-
-## Authentication
-
-  In both Node and browsers auth available via the `.auth()` method:
-
-    request
-      .get('http://local')
-      .auth('tobi', 'learnboost')
-      .end(callback);
-
-
-  In the _Node_ client Basic auth can be in the URL as "user:pass":
-
-    request.get('http://tobi:learnboost@local').end(callback);
-
-  By default only `Basic` auth is used. In browser you can add `{type:'auto'}` to enable all methods built-in in the browser (Digest, NTLM, etc.):
-
-    request.auth('digest', 'secret', {type:'auto'})
-
-## Following redirects
-
-  By default up to 5 redirects will be followed, however you may specify this with the `res.redirects(n)` method:
-
-    request
-      .get('/some.png')
-      .redirects(2)
-      .end(callback);
-
-## Piping data
-
-  The Node client allows you to pipe data to and from the request. For example piping a file's contents as the request:
-
-    var request = require('superagent')
-      , fs = require('fs');
-
-    var stream = fs.createReadStream('path/to/my.json');
-    var req = request.post('/somewhere');
-    req.type('json');
-    stream.pipe(req);
-
-  Or piping the response to a file:
-
-    var request = require('superagent')
-      , fs = require('fs');
-
-    var stream = fs.createWriteStream('path/to/my.json');
-    var req = request.get('/some.json');
-    req.pipe(stream);
-
-## Multipart requests
-
-  Super Agent is also great for _building_ multipart requests for which it provides methods `.attach()` and `.field()`.
-
-### Attaching files
-
-  As mentioned a higher-level API is also provided, in the form of `.attach(name, [path], [filename])` and `.field(name, value)`. Attaching several files is simple, you can also provide a custom filename for the attachment, otherwise the basename of the attached file is used.
-
-    request
-      .post('/upload')
-      .attach('avatar', 'path/to/tobi.png', 'user.png')
-      .attach('image', 'path/to/loki.png')
-      .attach('file', 'path/to/jane.png')
-      .end(callback);
-
-### Field values
-
-  Much like form fields in HTML, you can set field values with the `.field(name, value)` method. Suppose you want to upload a few images with your name and email, your request might look something like this:
-
-     request
-       .post('/upload')
-       .field('user[name]', 'Tobi')
-       .field('user[email]', 'tobi@learnboost.com')
-       .attach('image', 'path/to/tobi.png')
-       .end(callback);
-
-## Compression
-
-  The node client supports compressed responses, best of all, you don't have to do anything! It just works.
-
-## Buffering responses
-
-  To force buffering of response bodies as `res.text` you may invoke `req.buffer()`. To undo the default of buffering for text responses such
-  as "text/plain", "text/html" etc you may invoke `req.buffer(false)`.
-
-  When buffered the `res.buffered` flag is provided, you may use this to
-  handle both buffered and unbuffered responses in the same callback.
-
-## CORS
-
-  The `.withCredentials()` method enables the ability to send cookies
-  from the origin, however only when "Access-Control-Allow-Origin" is
-  _not_ a wildcard ("*"), and "Access-Control-Allow-Credentials" is "true".
-
-    request
-      .get('http://localhost:4001/')
-      .withCredentials()
-      .end(function(err, res){
-        assert(200 == res.status);
-        assert('tobi' == res.text);
-        next();
-      })
-
-## Error handling
-
-Your callback function will always be passed two arguments: error and response. If no error occurred, the first argument will be null:
-
-    request
-     .post('/upload')
-     .attach('image', 'path/to/tobi.png')
-     .end(function(err, res){
-
-     });
-
-     An "error" event is also emitted, with you can listen for:
-
-    request
-      .post('/upload')
-      .attach('image', 'path/to/tobi.png')
-      .on('error', handle)
-      .end(function(err, res){
-
-      });
-
-  Note that a 4xx or 5xx response with super agent **are** considered an error by default. For example if you get a 500 or 403 response, this status information will be available via `err.status`. Errors from such responses also contain an `err.response` field with all of the properties mentioned in "Response properties". The library behaves in this way to handle the common case of wanting success responses and treating HTTP error status codes as errors while still allowing for custom logic around specific error conditions.
-
-  Network failures, timeouts, and other errors that produce no response will contain no `err.status` or `err.response` fields.
-
-  If you wish to handle 404 or other HTTP error responses, you can query the `err.status` property.
-  When an HTTP error occurs (4xx or 5xx response) the `res.error` property is an `Error` object,
-  this allows you to perform checks such as:
-
-    if (err && err.status === 404) {
-      alert('oh no ' + res.body.message);
-    }
-    else if (err) {
-      // all other error types we handle generically
-    }
-
-## Promise and Generator support
-
-Superagent's request is a "thenable" object that's compatible with JavaScript promises and `async`/`await` syntax.
-
-Libraries like [co](https://github.com/tj/co) or a web framework like [koa](https://github.com/koajs/koa) can `yield` on any superagent method:
-
-    var res = yield request
-      .get('http://local')
-      .auth('tobi', 'learnboost')
-
-Note that superagent expects the global `Promise` object to be present. You'll need a polyfill to use promises in Internet Explorer or Node.js 0.10.
-
-
-## Browser and node versions
-
-Superagent has two implementations: one for web browsers (using XHR) and one for Node.JS (using core http module). By default Browserify and WebPack will pick the browser version.
-
-If want to use WebPack to compile code for Node.JS, you *must* specify [node target](webpack.github.io/docs/configuration.html#target) in its configuration.
-
-### Using browser version in electron
-
-[Electron](http://electron.atom.io/) developers report if you would prefer to use the browser version of superagent instead of the Node version, you can `require('superagent/superagent')`. Your requests will now show up in the Chrome developer tools Network tab. Note this environment is not covered by automated test suite and not officially supported.

-# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](https://travis-ci.org/component/emitter)

-

-  Event emitter component.

-

-## Installation

-

-```

-$ component install component/emitter

-```

-

-## API

-

-### Emitter(obj)

-

-  The `Emitter` may also be used as a mixin. For example

-  a "plain" object may become an emitter, or you may

-  extend an existing prototype.

-

-  As an `Emitter` instance:

-

-```js

-var Emitter = require('emitter');

-var emitter = new Emitter;

-emitter.emit('something');

-```

-

-  As a mixin:

-

-```js

-var Emitter = require('emitter');

-var user = { name: 'tobi' };

-Emitter(user);

-

-user.emit('im a user');

-```

-

-  As a prototype mixin:

-

-```js

-var Emitter = require('emitter');

-Emitter(User.prototype);

-```

-

-### Emitter#on(event, fn)

-

-  Register an `event` handler `fn`.

-

-### Emitter#once(event, fn)

-

-  Register a single-shot `event` handler `fn`,

-  removed immediately after it is invoked the

-  first time.

-

-### Emitter#off(event, fn)

-

-  * Pass `event` and `fn` to remove a listener.

-  * Pass `event` to remove all listeners on that event.

-  * Pass nothing to remove all listeners on all events.

-

-### Emitter#emit(event, ...)

-

-  Emit an `event` with variable option args.

-

-### Emitter#listeners(event)

-

-  Return an array of callbacks, or an empty array.

-

-### Emitter#hasListeners(event)

-

-  Check if this emitter has `event` handlers.

-

-# extend() for Node.js <sup>[![Version Badge][npm-version-png]][npm-url]</sup>
-
-`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
-
-## Installation
-
-This package is available on [npm][npm-url] as: `extend`
-
-``` sh
-npm install extend
-```
-
-## Usage
-
-**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)**
-
-*Extend one object with one or more others, returning the modified object.*
-
-Keep in mind that the target object will be modified, and will be returned from extend().
-
-If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
-Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
-Warning: passing `false` as the first argument is not supported.
-
-### Arguments
-
-* `deep` *Boolean* (optional)
-If set, the merge becomes recursive (i.e. deep copy).
-* `target`	*Object*
-The object to extend.
-* `object1`	*Object*
-The object that will be merged into the first.
-* `objectN` *Object* (Optional)
-More objects to merge into the first.
-
-## License
-
-`node-extend` is licensed under the [MIT License][mit-license-url].
-
-## Acknowledgements
-
-All credit to the jQuery authors for perfecting this amazing utility.

-A library to create readable ```"multipart/form-data"``` streams. Can be used to submit forms and file uploads to other web applications.
-
-The API of this library is inspired by the [XMLHttpRequest-2 FormData Interface][xhr2-fd].

-
-## Install
-
-```
-npm install form-data
-```
-
-## Usage
-
-In this example we are constructing a form with 3 fields that contain a string,
-a buffer and a file stream.
-
-``` javascript
-var FormData = require('form-data');
-var fs = require('fs');
-
-var form = new FormData();
-form.append('my_field', 'my value');
-form.append('my_buffer', new Buffer(10));
-form.append('my_file', fs.createReadStream('/foo/bar.jpg'));
-```
-
-Also you can use http-response stream:
-
-``` javascript
-var FormData = require('form-data');
-var http = require('http');
-
-var form = new FormData();
-
-http.request('http://nodejs.org/images/logo.png', function(response) {
-  form.append('my_field', 'my value');
-  form.append('my_buffer', new Buffer(10));
-  form.append('my_logo', response);
-});
-```
-
-Or @mikeal's [request](https://github.com/request/request) stream:
-
-``` javascript
-var FormData = require('form-data');
-var request = require('request');
-
-var form = new FormData();
-
-form.append('my_field', 'my value');
-form.append('my_buffer', new Buffer(10));
-form.append('my_logo', request('http://nodejs.org/images/logo.png'));
-```
-
-In order to submit this form to a web application, call ```submit(url, [callback])``` method:
-
-``` javascript
-form.submit('http://example.org/', function(err, res) {
-  // res – response object (http.IncomingMessage)  //
-  res.resume();
-});
-
-```
-
-For more advanced request manipulations ```submit()``` method returns ```http.ClientRequest``` object, or you can choose from one of the alternative submission methods.
-
-### Alternative submission methods
-
-You can use node's http client interface:
-
-``` javascript
-var http = require('http');
-
-var request = http.request({
-  method: 'post',
-  host: 'example.org',
-  path: '/upload',
-  headers: form.getHeaders()
-});
-
-form.pipe(request);
-
-request.on('response', function(res) {
-  console.log(res.statusCode);
-});
-```
-
-Or if you would prefer the `'Content-Length'` header to be set for you:
-
-``` javascript
-form.submit('example.org/upload', function(err, res) {
-  console.log(res.statusCode);
-});
-```
-
-To use custom headers and pre-known length in parts:
-
-``` javascript
-var CRLF = '\r\n';
-var form = new FormData();
-
-var options = {
-  header: CRLF + '--' + form.getBoundary() + CRLF + 'X-Custom-Header: 123' + CRLF + CRLF,
-  knownLength: 1
-};
-
-form.append('my_buffer', buffer, options);
-
-form.submit('http://example.com/', function(err, res) {
-  if (err) throw err;
-  console.log('Done');
-});
-```
-
-Form-Data can recognize and fetch all the required information from common types of streams (```fs.readStream```, ```http.response``` and ```mikeal's request```), for some other types of streams you'd need to provide "file"-related information manually:
-
-``` javascript
-someModule.stream(function(err, stdout, stderr) {
-  if (err) throw err;
-
-  var form = new FormData();
-
-  form.append('file', stdout, {
-    filename: 'unicycle.jpg',
-    contentType: 'image/jpg',
-    knownLength: 19806
-  });
-
-  form.submit('http://example.com/', function(err, res) {
-    if (err) throw err;
-    console.log('Done');
-  });
-});
-```
-
-For edge cases, like POST request to URL with query string or to pass HTTP auth credentials, object can be passed to `form.submit()` as first parameter:
-
-``` javascript
-form.submit({
-  host: 'example.com',
-  path: '/probably.php?extra=params',
-  auth: 'username:password'
-}, function(err, res) {
-  console.log(res.statusCode);
-});
-```
-
-In case you need to also send custom HTTP headers with the POST request, you can use the `headers` key in first parameter of `form.submit()`:
-
-``` javascript
-form.submit({
-  host: 'example.com',
-  path: '/surelynot.php',
-  headers: {'x-test-header': 'test-header-value'}
-}, function(err, res) {
-  console.log(res.statusCode);
-});
-```
-
-### Integration with other libraries
-
-#### Request
-
-Form submission using  [request](https://github.com/request/request):
-
-```javascript
-var formData = {
-  my_field: 'my_value',
-  my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
-};
-
-request.post({url:'http://service.com/upload', formData: formData}, function(err, httpResponse, body) {
-  if (err) {
-    return console.error('upload failed:', err);
-  }
-  console.log('Upload successful!  Server responded with:', body);
-});
-```
-
-For more details see [request readme](https://github.com/request/request#multipartform-data-multipart-form-uploads).
-
-#### node-fetch
-
-You can also submit a form using [node-fetch](https://github.com/bitinn/node-fetch):
-
-```javascript
-var form = new FormData();
-
-form.append('a', 1);
-
-fetch('http://example.com', { method: 'POST', body: form })
-    .then(function(res) {
-        return res.json();
-    }).then(function(json) {
-        console.log(json);
-    });
-```
-
-## Notes
-
-- ```getLengthSync()``` method DOESN'T calculate length for streams, use ```knownLength``` options as workaround.
-- If it feels like FormData hangs after submit and you're on ```node-0.10```, please check [Compatibility with Older Node Versions][streams2-thing]

-
-Async is a utility module which provides straight-forward, powerful functions
-for working with asynchronous JavaScript. Although originally designed for
-use with [Node.js](http://nodejs.org) and installable via `npm install async`,
-it can also be used directly in the browser.
-
-Async is also installable via:
-
-- [bower](http://bower.io/): `bower install async`
-- [component](https://github.com/component/component): `component install
-  caolan/async`
-- [jam](http://jamjs.org/): `jam install async`
-- [spm](http://spmjs.io/): `spm install async`
-
-Async provides around 20 functions that include the usual 'functional'
-suspects (`map`, `reduce`, `filter`, `each`…) as well as some common patterns
-for asynchronous control flow (`parallel`, `series`, `waterfall`…). All these
-functions assume you follow the Node.js convention of providing a single
-callback as the last argument of your `async` function.
-
-
-## Quick Examples
-
-```javascript
-async.map(['file1','file2','file3'], fs.stat, function(err, results){
-    // results is now an array of stats for each file
-});
-
-async.filter(['file1','file2','file3'], fs.exists, function(results){
-    // results now equals an array of the existing files
-});
-
-async.parallel([
-    function(){ ... },
-    function(){ ... }
-], callback);
-
-async.series([
-    function(){ ... },
-    function(){ ... }
-]);
-```
-
-There are many more functions available so take a look at the docs below for a
-full list. This module aims to be comprehensive, so if you feel anything is
-missing please create a GitHub issue for it.
-
-## Common Pitfalls <sub>[(StackOverflow)](http://stackoverflow.com/questions/tagged/async.js)</sub>
-### Synchronous iteration functions
-
-If you get an error like `RangeError: Maximum call stack size exceeded.` or other stack overflow issues when using async, you are likely using a synchronous iterator.  By *synchronous* we mean a function that calls its callback on the same tick in the javascript event loop, without doing any I/O or using any timers.  Calling many callbacks iteratively will quickly overflow the stack. If you run into this issue, just defer your callback with `async.setImmediate` to start a new call stack on the next tick of the event loop.
-
-This can also arise by accident if you callback early in certain cases:
-
-```js
-async.eachSeries(hugeArray, function iterator(item, callback) {
-  if (inCache(item)) {
-    callback(null, cache[item]); // if many items are cached, you'll overflow
-  } else {
-    doSomeIO(item, callback);
-  }
-}, function done() {
-  //...
-});
-```
-
-Just change it to:
-
-```js
-async.eachSeries(hugeArray, function iterator(item, callback) {
-  if (inCache(item)) {
-    async.setImmediate(function () {
-      callback(null, cache[item]);
-    });
-  } else {
-    doSomeIO(item, callback);
-  //...
-```
-
-Async guards against synchronous functions in some, but not all, cases.  If you are still running into stack overflows, you can defer as suggested above, or wrap functions with [`async.ensureAsync`](#ensureAsync)  Functions that are asynchronous by their nature do not have this problem and don't need the extra callback deferral.
-
-If JavaScript's event loop is still a bit nebulous, check out [this article](http://blog.carbonfive.com/2013/10/27/the-javascript-event-loop-explained/) or [this talk](http://2014.jsconf.eu/speakers/philip-roberts-what-the-heck-is-the-event-loop-anyway.html) for more detailed information about how it works.

-Make sure to always `return` when calling a callback early, otherwise you will cause multiple callbacks and unpredictable behavior in many cases.
-
-```js
-async.waterfall([
-    function (callback) {
-        getSomething(options, function (err, result) {
-          if (err) {
-            callback(new Error("failed getting something:" + err.message));
-            // we should return here
-          }
-          // since we did not return, this callback still will be called and
-          // `processData` will be called twice
-          callback(null, result);
-        });
-    },
-    processData
-], done)
-```
-
-It is always good practice to `return callback(err, result)`  whenever a callback call is not the last statement of a function.
-
-
-### Binding a context to an iterator
-
-This section is really about `bind`, not about `async`. If you are wondering how to
-make `async` execute your iterators in a given context, or are confused as to why
-a method of another library isn't working as an iterator, study this example:
-
-```js
-// Here is a simple object with an (unnecessarily roundabout) squaring method
-var AsyncSquaringLibrary = {
-  squareExponent: 2,
-  square: function(number, callback){
-    var result = Math.pow(number, this.squareExponent);
-    setTimeout(function(){
-      callback(null, result);
-    }, 200);
-  }
-};
-
-async.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){
-  // result is [NaN, NaN, NaN]
-  // This fails because the `this.squareExponent` expression in the square
-  // function is not evaluated in the context of AsyncSquaringLibrary, and is
-  // therefore undefined.
-});
-
-async.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){
-  // result is [1, 4, 9]
-  // With the help of bind we can attach a context to the iterator before
-  // passing it to async. Now the square function will be executed in its
-  // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent`
-  // will be as expected.
-});
-```

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

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

-error has occurred, the callback should be run without arguments or with an
-explicit `null` argument.
-* `callback(err)` - *Optional* A callback which is called when all `iterator` functions have finished, or an error occurs.

-<a name="map" />
-### map(arr, iterator, [callback])
-
-Produces a new array of values by mapping each value in `arr` through
-the `iterator` function. The `iterator` is called with an item from `arr` and a
-callback for when it has finished processing. Each of these callback takes 2 arguments:
-an `error`, and the transformed item from `arr`. If `iterator` passes an error to its
-callback, the main `callback` (for the `map` function) is immediately called with the error.
-
-Note, that since this function applies the `iterator` to each item in parallel,
-there is no guarantee that the `iterator` functions will complete in order.
-However, the results array will be in the same order as the original `arr`.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `iterator(item, callback)` - A function to apply to each item in `arr`.
-  The iterator is passed a `callback(err, transformed)` which must be called once
-  it has completed with an error (which can be `null`) and a transformed item.
-* `callback(err, results)` - *Optional* A callback which is called when all `iterator`
-  functions have finished, or an error occurs. Results is an array of the
-  transformed items from the `arr`.
-
-__Example__
-
-```js
-async.map(['file1','file2','file3'], fs.stat, function(err, results){
-    // results is now an array of stats for each file
-});

-### filter(arr, iterator, [callback])
-
-__Alias:__ `select`
-
-Returns a new array of all the values in `arr` which pass an async truth test.
-_The callback for each `iterator` call only accepts a single argument of `true` or
-`false`; it does not accept an error argument first!_ This is in-line with the
-way node libraries work with truth tests like `fs.exists`. This operation is
-performed in parallel, but the results array will be in the same order as the
-original.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
-  The `iterator` is passed a `callback(truthValue)`, which must be called with a
-  boolean argument once it has completed.
-* `callback(results)` - *Optional* A callback which is called after all the `iterator`
-  functions have finished.
-
-__Example__
-
-```js
-async.filter(['file1','file2','file3'], fs.exists, function(results){
-    // results now equals an array of the existing files

-
-<a name="reduce" />
-### reduce(arr, memo, iterator, [callback])
-
-__Aliases:__ `inject`, `foldl`
-
-Reduces `arr` into a single value using an async `iterator` to return
-each successive step. `memo` is the initial state of the reduction.
-This function only operates in series.
-
-For performance reasons, it may make sense to split a call to this function into
-a parallel map, and then use the normal `Array.prototype.reduce` on the results.
-This function is for situations where each step in the reduction needs to be async;
-if you can get the data before reducing it, then it's probably a good idea to do so.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `memo` - The initial state of the reduction.
-* `iterator(memo, item, callback)` - A function applied to each item in the
-  array to produce the next step in the reduction. The `iterator` is passed a
-  `callback(err, reduction)` which accepts an optional error as its first
-  argument, and the state of the reduction as the second. If an error is
-  passed to the callback, the reduction is stopped and the main `callback` is
-  immediately called with the error.
-* `callback(err, result)` - *Optional* A callback which is called after all the `iterator`
-  functions have finished. Result is the reduced value.
-
-__Example__
-
-```js
-async.reduce([1,2,3], 0, function(memo, item, callback){
-    // pointless async:
-    process.nextTick(function(){
-        callback(null, memo + item)
-    });
-}, function(err, result){
-    // result is now equal to the last value of memo, which is 6
-});
-```

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

-    // result now equals the first file in the list that exists
-});

-
-<a name="sortBy" />
-### sortBy(arr, iterator, [callback])
-
-Sorts a list by the results of running each `arr` value through an async `iterator`.
-
-__Arguments__
-
-* `arr` - An array to iterate over.
-* `iterator(item, callback)` - A function to apply to each item in `arr`.
-  The iterator is passed a `callback(err, sortValue)` which must be called once it
-  has completed with an error (which can be `null`) and a value to use as the sort
-  criteria.
-* `callback(err, results)` - *Optional* A callback which is called after all the `iterator`
-  functions have finished, or an error occurs. Results is the items from
-  the original `arr` sorted by the values returned by the `iterator` calls.
-
-__Example__
-
-```js
-async.sortBy(['file1','file2','file3'], function(file, callback){
-    fs.stat(file, function(err, stats){
-        callback(err, stats.mtime);
-    });
-}, function(err, results){
-    // results is now the original array of files sorted by
-    // modified date
-});
-```
-
-__Sort Order__
-
-By modifying the callback parameter the sorting order can be influenced:

-```js
-//ascending order
-async.sortBy([1,9,3,5], function(x, callback){
-    callback(null, x);
-}, function(err,result){

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

-        callback(null, 'two');
-    }
-],
-// optional callback

-
-<a name="parallel" />
-### parallel(tasks, [callback])
-
-Run the `tasks` array of functions in parallel, without waiting until the previous
-function has completed. If any of the functions pass an error to its
-callback, the main `callback` is immediately called with the value of the error.
-Once the `tasks` have completed, the results are passed to the final `callback` as an
-array.
-
-**Note:** `parallel` is about kicking-off I/O tasks in parallel, not about parallel execution of code.  If your tasks do not use any timers or perform any I/O, they will actually be executed in series.  Any synchronous setup sections for each task will happen one after the other.  JavaScript remains single-threaded.
-
-It is also possible to use an object instead of an array. Each property will be
-run as a function and the results will be passed to the final `callback` as an object
-instead of an array. This can be a more readable way of handling results from
-[`parallel`](#parallel).
-
-
-__Arguments__
-
-* `tasks` - An array or object containing functions to run. Each function is passed
-  a `callback(err, result)` which it must call on completion with an error `err`
-  (which can be `null`) and an optional `result` value.
-* `callback(err, results)` - An optional callback to run once all the functions
-  have completed successfully. This function gets a results array (or object) containing all
-  the result arguments passed to the task callbacks.
-
-__Example__
-
-```js
-async.parallel([
-    function(callback){
-        setTimeout(function(){
-            callback(null, 'one');

-<a name="whilst" />
-### whilst(test, fn, callback)
-
-Repeatedly call `fn`, while `test` returns `true`. Calls `callback` when stopped,
-or an error occurs.
-
-__Arguments__
-
-* `test()` - synchronous truth test to perform before each execution of `fn`.
-* `fn(callback)` - A function which is called each time `test` passes. The function is
-  passed a `callback(err)`, which must be called once it has completed with an
-  optional `err` argument.
-* `callback(err, [results])` - A callback which is called after the test
-  function has failed and repeated execution of `fn` has stopped. `callback`
-  will be passed an error and any arguments passed to the final `fn`'s callback.
-
-__Example__
-
-```js
-var count = 0;
-
-async.whilst(
-    function () { return count < 5; },
-    function (callback) {
-        count++;
-        setTimeout(function () {
-            callback(null, count);
-        }, 1000);

-### doWhilst(fn, test, callback)
-
-The post-check version of [`whilst`](#whilst). To reflect the difference in

-
-`doWhilst` is to `whilst` as `do while` is to `while` in plain JavaScript.
-
----------------------------------------
-
-<a name="until" />
-### until(test, fn, callback)
-
-Repeatedly call `fn` until `test` returns `true`. Calls `callback` when stopped,

-to the final `fn`'s callback.
-
-The inverse of [`whilst`](#whilst).
-
----------------------------------------
-
-<a name="doUntil" />

-Like [`doWhilst`](#doWhilst), except the `test` is inverted. Note the argument ordering differs from `until`.
-
----------------------------------------
-
-<a name="during" />
-### during(test, fn, callback)
-
-Like [`whilst`](#whilst), except the `test` is an asynchronous function that is passed a callback in the form of `function (err, truth)`. If error is passed to `test` or `fn`, the main callback is immediately called with the value of the error.
-
-__Example__
-
-```js
-var count = 0;
-
-async.during(
-    function (callback) {
-      return callback(null, count < 5);
-    },

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

----------------------------------------
-
-<a name="waterfall" />
-### waterfall(tasks, [callback])
-
-Runs the `tasks` array of functions in series, each passing their results to the next in
-the array. However, if any of the `tasks` pass an error to their own callback, the
-next function is not executed, and the main `callback` is immediately called with
-the error.
-
-__Arguments__
-
-* `tasks` - An array of functions to run, each function is passed a
-  `callback(err, result1, result2, ...)` it must call on completion. The first
-  argument is an error (which can be `null`) and any further arguments will be
-  passed as arguments in order to the next task.
-* `callback(err, [results])` - An optional callback to run once all the functions
-  have completed. This will be passed the results of the last task's callback.
-
-
-
-__Example__
-
-```js
-async.waterfall([
-    function(callback) {
-        callback(null, 'one', 'two');
-    },
-    function(arg1, arg2, callback) {
-      // arg1 now equals 'one' and arg2 now equals 'two'
-        callback(null, 'three');
-    },
-    function(arg1, callback) {
-        // arg1 now equals 'three'
-        callback(null, 'done');
-    }
-], function (err, result) {
-    // result now equals 'done'
-});
-```
-Or, with named functions:
-
-```js
-async.waterfall([
-    myFirstFunction,
-    mySecondFunction,
-    myLastFunction,
-], function (err, result) {
-    // result now equals 'done'
-});
-function myFirstFunction(callback) {
-  callback(null, 'one', 'two');
-}
-function mySecondFunction(arg1, arg2, callback) {
-  // arg1 now equals 'one' and arg2 now equals 'two'
-  callback(null, 'three');
-}
-function myLastFunction(arg1, callback) {
-  // arg1 now equals 'three'
-  callback(null, 'done');
-}
-```
-
-Or, if you need to pass any argument to the first function:
-
-```js
-async.waterfall([
-    async.apply(myFirstFunction, 'zero'),
-    mySecondFunction,
-    myLastFunction,
-], function (err, result) {
-    // result now equals 'done'
-});
-function myFirstFunction(arg1, callback) {
-  // arg1 now equals 'zero'
-  callback(null, 'one', 'two');
-}
-function mySecondFunction(arg1, arg2, callback) {
-  // arg1 now equals 'one' and arg2 now equals 'two'

-  // arg1 now equals 'three'
-  callback(null, 'done');
-}

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

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

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

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

-q.unshift({name: 'bar'}, function (err) {
-    console.log('finished processing bar');
-});

-
-<a name="priorityQueue" />
-### priorityQueue(worker, concurrency)
-
-The same as [`queue`](#queue) only tasks are assigned a priority and completed in ascending priority order. There are two differences between `queue` and `priorityQueue` objects:
-
-* `push(task, priority, [callback])` - `priority` should be a number. If an array of
-  `tasks` is given, all tasks will be assigned the same priority.
-* The `unshift` method was removed.
-
----------------------------------------
-
-<a name="cargo" />
-### cargo(worker, [payload])
-
-Creates a `cargo` object with the specified payload. Tasks added to the
-cargo will be processed altogether (up to the `payload` limit). If the
-`worker` is in progress, the task is queued until it becomes available. Once
-the `worker` has completed some tasks, each callback of those tasks is called.

-
-While [queue](#queue) passes only one task to one of a group of workers
-at a time, cargo passes an array of tasks to a single worker, repeating
-when the worker is finished.
-
-__Arguments__
-
-* `worker(tasks, callback)` - An asynchronous function for processing an array of
-  queued tasks, which must call its `callback(err)` argument when finished, with
-  an optional `err` argument.
-* `payload` - An optional `integer` for determining how many tasks should be
-  processed per round; if omitted, the default is unlimited.
-
-__Cargo objects__
-
-The `cargo` object returned by this function has the following properties and
-methods:
-
-* `length()` - A function returning the number of items waiting to be processed.
-* `payload` - An `integer` for determining how many tasks should be
-  process per round. This property can be changed after a `cargo` is created to
-  alter the payload on-the-fly.
-* `push(task, [callback])` - Adds `task` to the `queue`. The callback is called
-  once the `worker` has finished processing the task. Instead of a single task, an array of `tasks`
-  can be submitted. The respective callback is used for every task in the list.
-* `saturated` - A callback that is called when the `queue.length()` hits the concurrency and further tasks will be queued.
-* `empty` - A callback that is called when the last item from the `queue` is given to a `worker`.
-* `drain` - A callback that is called when the last item from the `queue` has returned from the `worker`.
-* `idle()`, `pause()`, `resume()`, `kill()` - cargo inherits all of the same methods and event calbacks as [`queue`](#queue)
-
-__Example__
-
-```js
-// create a cargo object with payload 2
-
-var cargo = async.cargo(function (tasks, callback) {
-    for(var i=0; i<tasks.length; i++){
-      console.log('hello ' + tasks[i].name);
-    }
-    callback();
-}, 2);
-
-
-// add some items
-
-cargo.push({name: 'foo'}, function (err) {
-    console.log('finished processing foo');
-});
-cargo.push({name: 'bar'}, function (err) {
-    console.log('finished processing bar');
-});
-cargo.push({name: 'baz'}, function (err) {
-    console.log('finished processing baz');
-});
-```
-
----------------------------------------
-
-<a name="auto" />
-### auto(tasks, [concurrency], [callback])
-
-Determines the best order for running the functions in `tasks`, based on their requirements. Each function can optionally depend on other functions being completed first, and each function is run as soon as its requirements are satisfied.
-
-If any of the functions pass an error to their callback, the `auto` sequence will stop. Further tasks will not execute (so any other functions depending on it will not run), and the main `callback` is immediately called with the error.  Functions also receive an object containing the results of functions which have completed so far.
-
-Note, all functions are called with a `results` object as a second argument,
-so it is unsafe to pass functions in the `tasks` object which cannot handle the
-extra argument.
-
-For example, this snippet of code:
-
-```js
-async.auto({
-  readData: async.apply(fs.readFile, 'data.txt', 'utf-8')
-}, callback);
-```
-
-will have the effect of calling `readFile` with the results object as the last
-argument, which will fail:
-
-```js
-fs.readFile('data.txt', 'utf-8', cb, {});
-```
-
-Instead, wrap the call to `readFile` in a function which does not forward the
-`results` object:
-
-```js
-async.auto({
-  readData: function(cb, results){
-    fs.readFile('data.txt', 'utf-8', cb);
-  }
-}, callback);
-```
-
-__Arguments__
-
-* `tasks` - An object. Each of its properties is either a function or an array of
-  requirements, with the function itself the last item in the array. The object's key
-  of a property serves as the name of the task defined by that property,
-  i.e. can be used when specifying requirements for other tasks.
-  The function receives two arguments: (1) a `callback(err, result)` which must be
-  called when finished, passing an `error` (which can be `null`) and the result of
-  the function's execution, and (2) a `results` object, containing the results of
-  the previously executed functions.
-* `concurrency` - An optional `integer` for determining the maximum number of tasks that can be run in parallel. By default, as many as possible.
-* `callback(err, results)` - An optional callback which is called when all the
-  tasks have been completed. It receives the `err` argument if any `tasks`
-  pass an error to their callback. Results are always returned; however, if
-  an error occurs, no further `tasks` will be performed, and the results
-  object will only contain partial results.
-
-
-__Example__
-
-```js
-async.auto({
-    get_data: function(callback){
-        console.log('in get_data');
-        // async code to get some data
-        callback(null, 'data', 'converted to array');
-    },
-    make_folder: function(callback){
-        console.log('in make_folder');
-        // async code to create a directory to store a file in
-        // this is run at the same time as getting the data
-        callback(null, 'folder');
-    },
-    write_file: ['get_data', 'make_folder', function(callback, results){
-        console.log('in write_file', JSON.stringify(results));
-        // once there is some data and the directory exists,
-        // write the data to a file in the directory
-        callback(null, 'filename');
-    }],
-    email_link: ['write_file', function(callback, results){
-        console.log('in email_link', JSON.stringify(results));
-        // once the file is written let's email a link to it...
-        // results.write_file contains the filename returned by write_file.
-        callback(null, {'file':results.write_file, 'email':'user@example.com'});
-    }]
-}, function(err, results) {
-    console.log('err = ', err);
-    console.log('results = ', results);
-});
-```
-
-This is a fairly trivial example, but to do this using the basic parallel and
-series functions would look like this:
-
-```js
-async.parallel([
-    function(callback){
-        console.log('in get_data');
-        // async code to get some data
-        callback(null, 'data', 'converted to array');
-    },
-    function(callback){
-        console.log('in make_folder');
-        // async code to create a directory to store a file in
-        // this is run at the same time as getting the data
-        callback(null, 'folder');
-    }
-],
-function(err, results){
-    async.series([
-        function(callback){
-            console.log('in write_file', JSON.stringify(results));
-            // once there is some data and the directory exists,
-            // write the data to a file in the directory
-            results.push('filename');
-            callback(null);
-        },
-        function(callback){
-            console.log('in email_link', JSON.stringify(results));
-            // once the file is written let's email a link to it...
-            callback(null, {'file':results.pop(), 'email':'user@example.com'});
-        }
-    ]);
-});
-```
-
-For a complicated series of `async` tasks, using the [`auto`](#auto) function makes adding
-new tasks much easier (and the code more readable).
-
-
----------------------------------------
-
-<a name="retry" />
-### retry([opts = {times: 5, interval: 0}| 5], task, [callback])
-
-Attempts to get a successful response from `task` no more than `times` times before
-returning an error. If the task is successful, the `callback` will be passed the result
-of the successful task. If all attempts fail, the callback will be passed the error and
-result (if any) of the final attempt.
-
-__Arguments__
-
-* `opts` - Can be either an object with `times` and `interval` or a number.
-  * `times` - The number of attempts to make before giving up.  The default is `5`.
-  * `interval` - The time to wait between retries, in milliseconds.  The default is `0`.
-  * If `opts` is a number, the number specifies the number of times to retry, with the default interval of `0`. 
-* `task(callback, results)` - A function which receives two arguments: (1) a `callback(err, result)`
-  which must be called when finished, passing `err` (which can be `null`) and the `result` of
-  the function's execution, and (2) a `results` object, containing the results of
-  the previously executed functions (if nested inside another control flow).
-* `callback(err, results)` - An optional callback which is called when the
-  task has succeeded, or after the final failed attempt. It receives the `err` and `result` arguments of the last attempt at completing the `task`.
-
-The [`retry`](#retry) function can be used as a stand-alone control flow by passing a callback, as shown below:
-
-```js
-// try calling apiMethod 3 times
-async.retry(3, apiMethod, function(err, result) {
-    // do something with the result
-});
-```
-
-```js
-// try calling apiMethod 3 times, waiting 200 ms between each retry 
-async.retry({times: 3, interval: 200}, apiMethod, function(err, result) {
-    // do something with the result
-});
-```
-
-```js
-// try calling apiMethod the default 5 times no delay between each retry 
-async.retry(apiMethod, function(err, result) {
-    // do something with the result
-});
-```
-
-It can also be embedded within other control flow functions to retry individual methods
-that are not as reliable, like this:
-
-```js
-async.auto({
-    users: api.getUsers.bind(api),
-    payments: async.retry(3, api.getPayments.bind(api))
-}, function(err, results) {
-  // do something with the results
-});
-```

-<a name="iterator" />
-### iterator(tasks)
-
-Creates an iterator function which calls the next function in the `tasks` array,
-returning a continuation to call the next one after that. It's also possible to
-“peek” at the next iterator with `iterator.next()`.
-
-This function is used internally by the `async` module, but can be useful when
-you want to manually control the flow of functions in series.
-
-__Arguments__
-
-* `tasks` - An array of functions to run.
-
-__Example__
-
-```js
-var iterator = async.iterator([
-    function(){ sys.p('one'); },
-    function(){ sys.p('two'); },
-    function(){ sys.p('three'); }
-]);
-
-node> var iterator2 = iterator();
-'one'
-node> var iterator3 = iterator2();
-'two'
-node> iterator3();
-'three'
-node> var nextfn = iterator2.next();
-node> nextfn();
-'three'
-```
-
----------------------------------------
-
-<a name="apply" />
-### apply(function, arguments..)
-
-Creates a continuation function with some arguments already applied.
-
-Useful as a shorthand when combined with other control flow functions. Any arguments
-passed to the returned function are added to the arguments originally passed
-to apply.
-
-__Arguments__
-
-* `function` - The function you want to eventually apply all arguments to.
-* `arguments...` - Any number of arguments to automatically apply when the
-  continuation is called.
-
-__Example__
-
-```js
-// using apply
-
-async.parallel([
-    async.apply(fs.writeFile, 'testfile1', 'test1'),
-    async.apply(fs.writeFile, 'testfile2', 'test2'),
-]);
-
-
-// the same process without using apply
-
-async.parallel([
-    function(callback){
-        fs.writeFile('testfile1', 'test1', callback);
-    },
-    function(callback){
-        fs.writeFile('testfile2', 'test2', callback);
-    }
-]);
-```
-
-It's possible to pass any number of additional arguments when calling the
-continuation:
-
-```js
-node> var fn = async.apply(sys.puts, 'one');
-node> fn('two', 'three');
-one
-two
-three
-```
-
----------------------------------------
-
-<a name="nextTick" />
-### nextTick(callback), setImmediate(callback)
-
-Calls `callback` on a later loop around the event loop. In Node.js this just
-calls `process.nextTick`; in the browser it falls back to `setImmediate(callback)`
-if available, otherwise `setTimeout(callback, 0)`, which means other higher priority
-events may precede the execution of `callback`.
-
-This is used internally for browser-compatibility purposes.
-
-__Arguments__
-
-* `callback` - The function to call on a later loop around the event loop.
-
-__Example__
-
-```js
-var call_order = [];
-async.nextTick(function(){
-    call_order.push('two');
-    // call_order now equals ['one','two']
-});
-call_order.push('one')
-```
-
-<a name="times" />
-### times(n, iterator, [callback])
-
-Calls the `iterator` function `n` times, and accumulates results in the same manner
-you would use with [`map`](#map).
-
-__Arguments__
-
-* `n` - The number of times to run the function.
-* `iterator` - The function to call `n` times.
-* `callback` - see [`map`](#map)
-
-__Example__
-
-```js
-// Pretend this is some complicated async factory
-var createUser = function(id, callback) {
-  callback(null, {
-    id: 'user' + id
-  })
-}
-// generate 5 users
-async.times(5, function(n, next){
-    createUser(n, function(err, user) {
-      next(err, user)
-    })
-}, function(err, users) {
-  // we should now have 5 users
-});
-```
-
-__Related__
-
-* timesSeries(n, iterator, [callback])
-* timesLimit(n, limit, iterator, [callback])

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

-# combined-stream
-
-A stream that emits multiple other streams one after another.
-
-**NB** Currently `combined-stream` works with streams vesrion 1 only. There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatability with `combined-stream`.
-
-- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module.
-
-- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another.
-
-## Installation
-
-``` bash
-npm install combined-stream
-```
-
-## Usage
-
-Here is a simple example that shows how you can use combined-stream to combine
-two files into one:
-
-``` javascript
-var CombinedStream = require('combined-stream');
-var fs = require('fs');
-
-var combinedStream = CombinedStream.create();
-combinedStream.append(fs.createReadStream('file1.txt'));
-combinedStream.append(fs.createReadStream('file2.txt'));
-
-combinedStream.pipe(fs.createWriteStream('combined.txt'));
-```
-
-While the example above works great, it will pause all source streams until
-they are needed. If you don't want that to happen, you can set `pauseStreams`
-to `false`:
-
-``` javascript
-var CombinedStream = require('combined-stream');
-var fs = require('fs');
-
-var combinedStream = CombinedStream.create({pauseStreams: false});
-combinedStream.append(fs.createReadStream('file1.txt'));
-combinedStream.append(fs.createReadStream('file2.txt'));
-
-combinedStream.pipe(fs.createWriteStream('combined.txt'));
-```
-
-However, what if you don't have all the source streams yet, or you don't want
-to allocate the resources (file descriptors, memory, etc.) for them right away?
-Well, in that case you can simply provide a callback that supplies the stream
-by calling a `next()` function:
-
-``` javascript
-var CombinedStream = require('combined-stream');
-var fs = require('fs');
-
-var combinedStream = CombinedStream.create();
-combinedStream.append(function(next) {
-  next(fs.createReadStream('file1.txt'));
-});
-combinedStream.append(function(next) {
-  next(fs.createReadStream('file2.txt'));
-});
-
-combinedStream.pipe(fs.createWriteStream('combined.txt'));
-```
-
-## API
-
-### CombinedStream.create([options])
-
-Returns a new combined stream object. Available options are:
-
-* `maxDataSize`
-* `pauseStreams`
-
-The effect of those options is described below.
-
-### combinedStream.pauseStreams = `true`
-
-Whether to apply back pressure to the underlaying streams. If set to `false`,
-the underlaying streams will never be paused. If set to `true`, the
-underlaying streams will be paused right after being appended, as well as when
-`delayedStream.pipe()` wants to throttle.
-
-### combinedStream.maxDataSize = `2 * 1024 * 1024`
-
-The maximum amount of bytes (or characters) to buffer for all source streams.
-If this value is exceeded, `combinedStream` emits an `'error'` event.
-
-### combinedStream.dataSize = `0`
-
-The amount of bytes (or characters) currently buffered by `combinedStream`.
-
-### combinedStream.append(stream)
-
-Appends the given `stream` to the combinedStream object. If `pauseStreams` is
-set to `true, this stream will also be paused right away.
-
-`streams` can also be a function that takes one parameter called `next`. `next`
-is a function that must be invoked in order to provide the `next` stream, see
-example above.
-
-Regardless of how the `stream` is appended, combined-stream always attaches an
-`'error'` listener to it, so you don't have to do that manually.
-
-Special case: `stream` can also be a String or Buffer.
-
-### combinedStream.write(data)
-
-You should not call this, `combinedStream` takes care of piping the appended
-streams into itself for you.
-
-### combinedStream.resume()
-
-Causes `combinedStream` to start drain the streams it manages. The function is
-idempotent, and also emits a `'resume'` event each time which usually goes to
-the stream that is currently being drained.
-
-### combinedStream.pause();
-
-If `combinedStream.pauseStreams` is set to `false`, this does nothing.
-Otherwise a `'pause'` event is emitted, this goes to the stream that is
-currently being drained, so you can use it to apply back pressure.
-
-### combinedStream.end();
-
-Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
-all streams from the queue.
-
-### combinedStream.destroy();
-
-Same as `combinedStream.end()`, except it emits a `'close'` event instead of
-`'end'`.

-# delayed-stream
-
-Buffers events from a stream until you are ready to handle them.
-
-## Installation
-
-``` bash
-npm install delayed-stream
-```
-
-## Usage
-
-The following example shows how to write a http echo server that delays its
-response by 1000 ms.
-
-``` javascript
-var DelayedStream = require('delayed-stream');
-var http = require('http');
-
-http.createServer(function(req, res) {
-  var delayed = DelayedStream.create(req);
-
-  setTimeout(function() {
-    res.writeHead(200);
-    delayed.pipe(res);
-  }, 1000);
-});
-```
-
-If you are not using `Stream#pipe`, you can also manually release the buffered
-events by calling `delayedStream.resume()`:
-
-``` javascript
-var delayed = DelayedStream.create(req);
-
-setTimeout(function() {
-  // Emit all buffered events and resume underlaying source
-  delayed.resume();
-}, 1000);
-```
-
-## Implementation
-
-In order to use this meta stream properly, here are a few things you should
-know about the implementation.
-
-### Event Buffering / Proxying
-
-All events of the `source` stream are hijacked by overwriting the `source.emit`
-method. Until node implements a catch-all event listener, this is the only way.
-
-However, delayed-stream still continues to emit all events it captures on the
-`source`, regardless of whether you have released the delayed stream yet or
-not.
-
-Upon creation, delayed-stream captures all `source` events and stores them in
-an internal event buffer. Once `delayedStream.release()` is called, all
-buffered events are emitted on the `delayedStream`, and the event buffer is
-cleared. After that, delayed-stream merely acts as a proxy for the underlaying
-source.
-
-### Error handling
-
-Error events on `source` are buffered / proxied just like any other events.
-However, `delayedStream.create` attaches a no-op `'error'` listener to the
-`source`. This way you only have to handle errors on the `delayedStream`
-object, rather than in two places.
-
-### Buffer limits
-
-delayed-stream provides a `maxDataSize` property that can be used to limit
-the amount of data being buffered. In order to protect you from bad `source`
-streams that don't react to `source.pause()`, this feature is enabled by
-default.
-
-## API
-
-### DelayedStream.create(source, [options])
-
-Returns a new `delayedStream`. Available options are:
-
-* `pauseStream`
-* `maxDataSize`
-
-The description for those properties can be found below.
-
-### delayedStream.source
-
-The `source` stream managed by this object. This is useful if you are
-passing your `delayedStream` around, and you still want to access properties
-on the `source` object.
-
-### delayedStream.pauseStream = true
-
-Whether to pause the underlaying `source` when calling
-`DelayedStream.create()`. Modifying this property afterwards has no effect.
-
-### delayedStream.maxDataSize = 1024 * 1024
-
-The amount of data to buffer before emitting an `error`.
-
-If the underlaying source is emitting `Buffer` objects, the `maxDataSize`
-refers to bytes.
-
-If the underlaying source is emitting JavaScript strings, the size refers to
-characters.
-
-If you know what you are doing, you can set this property to `Infinity` to
-disable this feature. You can also modify this property during runtime.
-
-### delayedStream.dataSize = 0
-
-The amount of data buffered so far.
-
-### delayedStream.readable
-
-An ECMA5 getter that returns the value of `source.readable`.
-
-### delayedStream.resume()
-
-If the `delayedStream` has not been released so far, `delayedStream.release()`
-is called.
-
-In either case, `source.resume()` is called.
-
-### delayedStream.pause()
-
-Calls `source.pause()`.
-
-### delayedStream.pipe(dest)
-
-Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`.
-
-### delayedStream.release()
-
-Emits and clears all events that have been buffered up so far. This does not
-resume the underlaying source, use `delayedStream.resume()` instead.

-[![NPM Version][npm-image]][npm-url]
-[![NPM Downloads][downloads-image]][downloads-url]

-
-The ultimate javascript content-type utility.
-
-Similar to [node-mime](https://github.com/broofa/node-mime), except:
-
-- __No fallbacks.__ Instead of naively returning the first available type, `mime-types` simply returns `false`,
-  so do `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
-- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
-- Additional mime types are added such as jade and stylus via [mime-db](https://github.com/jshttp/mime-db)
-- No `.define()` functionality
-
-Otherwise, the API is compatible.
-
-## Install
-
-```sh
-$ npm install mime-types
-```
-
-## Adding Types
-
-All mime types are based on [mime-db](https://github.com/jshttp/mime-db),
-so open a PR there if you'd like to add mime types.
-
-## API
-
-```js
-var mime = require('mime-types')
-```
-
-All functions return `false` if input is invalid or not found.
-
-### mime.lookup(path)
-
-Lookup the content-type associated with a file.
-
-```js
-mime.lookup('json')             // 'application/json'
-mime.lookup('.md')              // 'text/x-markdown'
-mime.lookup('file.html')        // 'text/html'
-mime.lookup('folder/file.js')   // 'application/javascript'
-mime.lookup('folder/.htaccess') // false
-
-mime.lookup('cats') // false
-```
-
-### mime.contentType(type)
-
-Create a full content-type header given a content-type or extension.
-
-```js
-mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
-mime.contentType('file.json') // 'application/json; charset=utf-8'
-
-// from a full path
-mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
-```
-
-### mime.extension(type)
-
-Get the default extension for a content-type.
-
-```js
-mime.extension('application/octet-stream') // 'bin'
-```
-
-### mime.charset(type)
-
-Lookup the implied default charset of a content-type.
-
-```js
-mime.charset('text/x-markdown') // 'UTF-8'
-```
-
-### var type = mime.types[extension]
-
-A map of content-types by extension.
-
-### [extensions...] = mime.extensions[type]
-
-A map of extensions by content-type.

-# mime-db
-
-[![NPM Version][npm-version-image]][npm-url]
-[![NPM Downloads][npm-downloads-image]][npm-url]
-[![Node.js Version][node-image]][node-url]
-[![Build Status][travis-image]][travis-url]

-
-This is a database of all mime types.
-It consists of a single, public JSON file and does not include any logic,
-allowing it to remain as un-opinionated as possible with an API.
-It aggregates data from the following sources:
-
-- http://www.iana.org/assignments/media-types/media-types.xhtml
-- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
-- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
-
-## Installation
-
-```bash
-npm install mime-db
-```
-
-### Database Download
-
-If you're crazy enough to use this in the browser, you can just grab the
-JSON file using [RawGit](https://rawgit.com/). It is recommended to replace
-`master` with [a release tag](https://github.com/jshttp/mime-db/tags) as the
-JSON format may change in the future.
-
-```
-https://cdn.rawgit.com/jshttp/mime-db/master/db.json
-```
-
-## Usage
-
-```js
-var db = require('mime-db');
-
-// grab data on .js files
-var data = db['application/javascript'];
-```
-
-## Data Structure
-
-The JSON file is a map lookup for lowercased mime types.
-Each mime type has the following properties:
-
-- `.source` - where the mime type is defined.
-    If not set, it's probably a custom media type.
-    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
-    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
-    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
-- `.extensions[]` - known extensions associated with this mime type.
-- `.compressible` - whether a file of this type can be gzipped.
-- `.charset` - the default charset associated with this type, if any.
-
-If unknown, every property could be `undefined`.
-
-## Contributing
-
-To edit the database, only make PRs against `src/custom.json` or
-`src/custom-suffix.json`.
-
-To update the build, run `npm run build`.
-
-## Adding Custom Media Types
-
-The best way to get new media types included in this library is to register
-them with the IANA. The community registration procedure is outlined in
-[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
-registered with the IANA are automatically pulled into this library.

-# Formidable
-
-[![Build Status](https://secure.travis-ci.org/felixge/node-formidable.png?branch=master)](http://travis-ci.org/felixge/node-formidable)
-
-## Purpose
-
-A node.js module for parsing form data, especially file uploads.
-
-## Current status
-
-This module was developed for [Transloadit](http://transloadit.com/), a service focused on uploading
-and encoding images and videos. It has been battle-tested against hundreds of GB of file uploads from
-a large variety of clients and is considered production-ready.
-
-## Features
-
-* Fast (~500mb/sec), non-buffering multipart parser
-* Automatically writing file uploads to disk
-* Low memory footprint
-* Graceful error handling
-* Very high test coverage
-
-## Installation
-
-This is a low level package, and if you're using a high level framework such as Express, chances are it's already included in it. You can [read this discussion](http://stackoverflow.com/questions/11295554/how-to-disable-express-bodyparser-for-file-uploads-node-js) about how Formidable is integrated with Express.
-
-Via [npm](http://github.com/isaacs/npm):
-```
-npm install formidable@latest
-```
-Manually:
-```
-git clone git://github.com/felixge/node-formidable.git formidable
-vim my.js
-# var formidable = require('./formidable');
-```
-
-Note: Formidable requires [gently](http://github.com/felixge/node-gently) to run the unit tests, but you won't need it for just using the library.
-
-## Example
-
-Parse an incoming file upload.
-```javascript
-var formidable = require('formidable'),
-    http = require('http'),
-    util = require('util');
-
-http.createServer(function(req, res) {
-  if (req.url == '/upload' && req.method.toLowerCase() == 'post') {
-    // parse a file upload
-    var form = new formidable.IncomingForm();
-
-    form.parse(req, function(err, fields, files) {
-      res.writeHead(200, {'content-type': 'text/plain'});
-      res.write('received upload:\n\n');
-      res.end(util.inspect({fields: fields, files: files}));
-    });
-
-    return;
-  }
-
-  // show a file upload form
-  res.writeHead(200, {'content-type': 'text/html'});
-  res.end(
-    '<form action="/upload" enctype="multipart/form-data" method="post">'+
-    '<input type="text" name="title"><br>'+
-    '<input type="file" name="upload" multiple="multiple"><br>'+
-    '<input type="submit" value="Upload">'+
-    '</form>'
-  );
-}).listen(8080);
-```
-## API
-
-### Formidable.IncomingForm
-```javascript
-var form = new formidable.IncomingForm()
-```
-Creates a new incoming form.
-
-```javascript
-form.encoding = 'utf-8';
-```
-Sets encoding for incoming form fields.
-
-```javascript
-form.uploadDir = "/my/dir";
-```
-Sets the directory for placing file uploads in. You can move them later on using
-`fs.rename()`. The default is `os.tmpDir()`.
-
-```javascript
-form.keepExtensions = false;
-```
-If you want the files written to `form.uploadDir` to include the extensions of the original files, set this property to `true`.
-
-```javascript
-form.type
-```
-Either 'multipart' or 'urlencoded' depending on the incoming request.
-
-```javascript
-form.maxFieldsSize = 2 * 1024 * 1024;
-```
-Limits the amount of memory all fields together (except files) can allocate in bytes.
-If this value is exceeded, an `'error'` event is emitted. The default
-size is 2MB.
-
-```javascript
-form.maxFields = 1000;
-```
-Limits the number of fields that the querystring parser will decode. Defaults
-to 1000 (0 for unlimited).
-
-```javascript
-form.hash = false;
-```
-If you want checksums calculated for incoming files, set this to either `'sha1'` or `'md5'`.
-
-```javascript
-form.multiples = false;
-```
-If this option is enabled, when you call `form.parse`, the `files` argument will contain arrays of files for inputs which submit multiple files using the HTML5 `multiple` attribute.
-
-```javascript
-form.bytesReceived
-```
-The amount of bytes received for this form so far.
-
-```javascript
-form.bytesExpected
-```
-The expected number of bytes in this form.
-
-```javascript
-form.parse(request, [cb]);
-```
-Parses an incoming node.js `request` containing form data. If `cb` is provided, all fields and files are collected and passed to the callback:
-
-
-```javascript
-form.parse(req, function(err, fields, files) {
-  // ...
-});
-
-form.onPart(part);
-```
-You may overwrite this method if you are interested in directly accessing the multipart stream. Doing so will disable any `'field'` / `'file'` events  processing which would occur otherwise, making you fully responsible for handling the processing.
-
-```javascript
-form.onPart = function(part) {
-  part.addListener('data', function() {
-    // ...
-  });
-}
-```
-If you want to use formidable to only handle certain parts for you, you can do so:
-```javascript
-form.onPart = function(part) {
-  if (!part.filename) {
-    // let formidable handle all non-file parts
-    form.handlePart(part);
-  }
-}
-```
-Check the code in this method for further inspiration.
-
-
-### Formidable.File
-```javascript
-file.size = 0
-```
-The size of the uploaded file in bytes. If the file is still being uploaded (see `'fileBegin'` event), this property says how many bytes of the file have been written to disk yet.
-```javascript
-file.path = null
-```
-The path this file is being written to. You can modify this in the `'fileBegin'` event in
-case you are unhappy with the way formidable generates a temporary path for your files.
-```javascript
-file.name = null
-```
-The name this file had according to the uploading client.
-```javascript
-file.type = null
-```
-The mime type of this file, according to the uploading client.
-```javascript
-file.lastModifiedDate = null
-```
-A date object (or `null`) containing the time this file was last written to. Mostly
-here for compatibility with the [W3C File API Draft](http://dev.w3.org/2006/webapi/FileAPI/).
-```javascript
-file.hash = null
-```
-If hash calculation was set, you can read the hex digest out of this var.
-
-#### Formidable.File#toJSON()
-
-  This method returns a JSON-representation of the file, allowing you to
-  `JSON.stringify()` the file which is useful for logging and responding
-  to requests.
-
-### Events
-
-
-#### 'progress'
-```javascript
-form.on('progress', function(bytesReceived, bytesExpected) {
-});
-```
-Emitted after each incoming chunk of data that has been parsed. Can be used to roll your own progress bar.
-
-
-
-#### 'field'
-```javascript
-form.on('field', function(name, value) {
-});
-```
-
-#### 'fileBegin'
-
-Emitted whenever a field / value pair has been received.
-```javascript
-form.on('fileBegin', function(name, file) {
-});
-```
-
-#### 'file'
-
-Emitted whenever a new file is detected in the upload stream. Use this even if
-you want to stream the file to somewhere else while buffering the upload on
-the file system.
-
-Emitted whenever a field / file pair has been received. `file` is an instance of `File`.
-```javascript
-form.on('file', function(name, file) {
-});
-```
-
-#### 'error'
-
-Emitted when there is an error processing the incoming form. A request that experiences an error is automatically paused, you will have to manually call `request.resume()` if you want the request to continue firing `'data'` events.
-```javascript
-form.on('error', function(err) {
-});
-```
-
-#### 'aborted'
-
-
-Emitted when the request was aborted by the user. Right now this can be due to a 'timeout' or 'close' event on the socket. After this event is emitted, an `error` event will follow. In the future there will be a separate 'timeout' event (needs a change in the node core).
-```javascript
-form.on('aborted', function() {
-});
-```
-
-##### 'end'
-```javascript
-form.on('end', function() {
-});
-```
-Emitted when the entire request has been received, and all contained files have finished flushing to disk. This is a great place for you to send your response.

-# mime
-
-Comprehensive MIME type mapping API based on mime-db module.
-
-## Install
-
-Install with [npm](http://github.com/isaacs/npm):
-
-    npm install mime
-
-## Contributing / Testing
-
-    npm run test
-
-## Command Line
-
-    mime [path_string]
-
-E.g.
-
-    > mime scripts/jquery.js
-    application/javascript
-
-## API - Queries
-
-### mime.lookup(path)
-Get the mime type associated with a file, if no mime type is found `application/octet-stream` is returned. Performs a case-insensitive lookup using the extension in `path` (the substring after the last '/' or '.').  E.g.
-
-```js
-var mime = require('mime');
-
-mime.lookup('/path/to/file.txt');         // => 'text/plain'
-mime.lookup('file.txt');                  // => 'text/plain'
-mime.lookup('.TXT');                      // => 'text/plain'
-mime.lookup('htm');                       // => 'text/html'
-```
-
-### mime.default_type
-Sets the mime type returned when `mime.lookup` fails to find the extension searched for. (Default is `application/octet-stream`.)
-
-### mime.extension(type)
-Get the default extension for `type`
-
-```js
-mime.extension('text/html');                 // => 'html'
-mime.extension('application/octet-stream');  // => 'bin'
-```
-
-### mime.charsets.lookup()
-
-Map mime-type to charset
-
-```js
-mime.charsets.lookup('text/plain');        // => 'UTF-8'
-```
-
-(The logic for charset lookups is pretty rudimentary.  Feel free to suggest improvements.)
-
-## API - Defining Custom Types
-
-Custom type mappings can be added on a per-project basis via the following APIs.
-
-### mime.define()
-
-Add custom mime/extension mappings
-
-```js
-mime.define({
-    'text/x-some-format': ['x-sf', 'x-sft', 'x-sfml'],
-    'application/x-my-type': ['x-mt', 'x-mtt'],
-    // etc ...
-});
-
-mime.lookup('x-sft');                 // => 'text/x-some-format'
-```
-
-The first entry in the extensions array is returned by `mime.extension()`. E.g.
-
-```js
-mime.extension('text/x-some-format'); // => 'x-sf'
-```
-
-### mime.load(filepath)
-
-Load mappings from an Apache ".types" format file
-
-```js
-mime.load('./my_project.types');
-```
-The .types file format is simple -  See the `types` dir for examples.

-# Stream
-
-    Stability: 2 - Stable
-
-A stream is an abstract interface implemented by various objects in
-Node.js. For example a [request to an HTTP server][http-incoming-message] is a
-stream, as is [`process.stdout`][]. Streams are readable, writable, or both. All
-streams are instances of [`EventEmitter`][].
-
-You can load the Stream base classes by doing `require('stream')`.
-There are base classes provided for [Readable][] streams, [Writable][]
-streams, [Duplex][] streams, and [Transform][] streams.
-
-This document is split up into 3 sections:
-
-1. The first section explains the parts of the API that you need to be
-   aware of to use streams in your programs.
-2. The second section explains the parts of the API that you need to
-   use if you implement your own custom streams yourself. The API is designed to
-   make this easy for you to do.
-3. The third section goes into more depth about how streams work,
-   including some of the internal mechanisms and functions that you
-   should probably not modify unless you definitely know what you are
-   doing.
-
-
-## API for Stream Consumers
-
-<!--type=misc-->
-
-Streams can be either [Readable][], [Writable][], or both ([Duplex][]).
-
-All streams are EventEmitters, but they also have other custom methods
-and properties depending on whether they are Readable, Writable, or
-Duplex.
-
-If a stream is both Readable and Writable, then it implements all of
-the methods and events. So, a [Duplex][] or [Transform][] stream is
-fully described by this API, though their implementation may be
-somewhat different.
-
-It is not necessary to implement Stream interfaces in order to consume
-streams in your programs. If you **are** implementing streaming
-interfaces in your own program, please also refer to
-[API for Stream Implementors][].
-
-Almost all Node.js programs, no matter how simple, use Streams in some
-way. Here is an example of using Streams in an Node.js program:
-
-```js
-const http = require('http');
-
-var server = http.createServer( (req, res) => {
-  // req is an http.IncomingMessage, which is a Readable Stream
-  // res is an http.ServerResponse, which is a Writable Stream
-
-  var body = '';
-  // we want to get the data as utf8 strings
-  // If you don't set an encoding, then you'll get Buffer objects
-  req.setEncoding('utf8');
-
-  // Readable streams emit 'data' events once a listener is added
-  req.on('data', (chunk) => {
-    body += chunk;
-  });
-
-  // the end event tells you that you have entire body
-  req.on('end', () => {
-    try {
-      var data = JSON.parse(body);
-    } catch (er) {
-      // uh oh!  bad json!
-      res.statusCode = 400;
-      return res.end(`error: ${er.message}`);
-    }
-
-    // write back something interesting to the user:
-    res.write(typeof data);
-    res.end();
-  });
-});
-
-server.listen(1337);
-
-// $ curl localhost:1337 -d '{}'
-// object
-// $ curl localhost:1337 -d '"foo"'
-// string
-// $ curl localhost:1337 -d 'not json'
-// error: Unexpected token o
-```
-
-### Class: stream.Duplex
-
-Duplex streams are streams that implement both the [Readable][] and
-[Writable][] interfaces.
-
-Examples of Duplex streams include:
-
-* [TCP sockets][]
-* [zlib streams][zlib]
-* [crypto streams][crypto]
-
-### Class: stream.Readable
-
-<!--type=class-->
-
-The Readable stream interface is the abstraction for a *source* of
-data that you are reading from. In other words, data comes *out* of a
-Readable stream.
-
-A Readable stream will not start emitting data until you indicate that
-you are ready to receive it.
-
-Readable streams have two "modes": a **flowing mode** and a **paused
-mode**. When in flowing mode, data is read from the underlying system
-and provided to your program as fast as possible. In paused mode, you
-must explicitly call [`stream.read()`][stream-read] to get chunks of data out.
-Streams start out in paused mode.
-
-**Note**: If no data event handlers are attached, and there are no
-[`stream.pipe()`][] destinations, and the stream is switched into flowing
-mode, then data will be lost.
-
-You can switch to flowing mode by doing any of the following:
-
-* Adding a [`'data'`][] event handler to listen for data.
-* Calling the [`stream.resume()`][stream-resume] method to explicitly open the
-  flow.
-* Calling the [`stream.pipe()`][] method to send the data to a [Writable][].
-
-You can switch back to paused mode by doing either of the following:
-
-* If there are no pipe destinations, by calling the
-  [`stream.pause()`][stream-pause] method.
-* If there are pipe destinations, by removing any [`'data'`][] event
-  handlers, and removing all pipe destinations by calling the
-  [`stream.unpipe()`][] method.
-
-Note that, for backwards compatibility reasons, removing [`'data'`][]
-event handlers will **not** automatically pause the stream. Also, if
-there are piped destinations, then calling [`stream.pause()`][stream-pause] will
-not guarantee that the stream will *remain* paused once those
-destinations drain and ask for more data.
-
-Examples of readable streams include:
-
-* [HTTP responses, on the client][http-incoming-message]
-* [HTTP requests, on the server][http-incoming-message]
-* [fs read streams][]
-* [zlib streams][zlib]
-* [crypto streams][crypto]
-* [TCP sockets][]
-* [child process stdout and stderr][]
-* [`process.stdin`][]
-
-#### Event: 'close'
-
-Emitted when the stream and any of its underlying resources (a file
-descriptor, for example) have been closed. The event indicates that
-no more events will be emitted, and no further computation will occur.
-
-Not all streams will emit the `'close'` event as the `'close'` event is
-optional.
-
-#### Event: 'data'
-
-* `chunk` {Buffer|String} The chunk of data.
-
-Attaching a `'data'` event listener to a stream that has not been
-explicitly paused will switch the stream into flowing mode. Data will
-then be passed as soon as it is available.
-
-If you just want to get all the data out of the stream as fast as
-possible, this is the best way to do so.
-
-```js
-var readable = getReadableStreamSomehow();
-readable.on('data', (chunk) => {
-  console.log('got %d bytes of data', chunk.length);
-});
-```
-
-#### Event: 'end'
-
-This event fires when there will be no more data to read.
-
-Note that the `'end'` event **will not fire** unless the data is
-completely consumed. This can be done by switching into flowing mode,
-or by calling [`stream.read()`][stream-read] repeatedly until you get to the
-end.
-
-```js
-var readable = getReadableStreamSomehow();
-readable.on('data', (chunk) => {
-  console.log('got %d bytes of data', chunk.length);
-});
-readable.on('end', () => {
-  console.log('there will be no more data.');
-});
-```
-
-#### Event: 'error'
-
-* {Error}
-
-Emitted if there was an error receiving data.
-
-#### Event: 'readable'
-
-When a chunk of data can be read from the stream, it will emit a
-`'readable'` event.
-
-In some cases, listening for a `'readable'` event will cause some data
-to be read into the internal buffer from the underlying system, if it
-hadn't already.
-
-```javascript
-var readable = getReadableStreamSomehow();
-readable.on('readable', () => {
-  // there is some data to read now
-});
-```
-
-Once the internal buffer is drained, a `'readable'` event will fire
-again when more data is available.
-
-The `'readable'` event is not emitted in the "flowing" mode with the
-sole exception of the last one, on end-of-stream.
-
-The `'readable'` event indicates that the stream has new information:
-either new data is available or the end of the stream has been reached.
-In the former case, [`stream.read()`][stream-read] will return that data. In the
-latter case, [`stream.read()`][stream-read] will return null. For instance, in
-the following example, `foo.txt` is an empty file:
-
-```js
-const fs = require('fs');
-var rr = fs.createReadStream('foo.txt');
-rr.on('readable', () => {
-  console.log('readable:', rr.read());
-});
-rr.on('end', () => {
-  console.log('end');
-});
-```
-
-The output of running this script is:
-
-```
-$ node test.js
-readable: null
-end
-```
-
-#### readable.isPaused()
-
-* Return: {Boolean}
-
-This method returns whether or not the `readable` has been **explicitly**
-paused by client code (using [`stream.pause()`][stream-pause] without a
-corresponding [`stream.resume()`][stream-resume]).
-
-```js
-var readable = new stream.Readable
-
-readable.isPaused() // === false
-readable.pause()
-readable.isPaused() // === true
-readable.resume()
-readable.isPaused() // === false
-```
-
-#### readable.pause()
-
-* Return: `this`
-
-This method will cause a stream in flowing mode to stop emitting
-[`'data'`][] events, switching out of flowing mode. Any data that becomes
-available will remain in the internal buffer.
-
-```js
-var readable = getReadableStreamSomehow();
-readable.on('data', (chunk) => {
-  console.log('got %d bytes of data', chunk.length);
-  readable.pause();
-  console.log('there will be no more data for 1 second');
-  setTimeout(() => {
-    console.log('now data will start flowing again');
-    readable.resume();
-  }, 1000);
-});
-```
-
-#### readable.pipe(destination[, options])
-
-* `destination` {stream.Writable} The destination for writing data
-* `options` {Object} Pipe options
-  * `end` {Boolean} End the writer when the reader ends. Default = `true`
-
-This method pulls all the data out of a readable stream, and writes it
-to the supplied destination, automatically managing the flow so that
-the destination is not overwhelmed by a fast readable stream.
-
-Multiple destinations can be piped to safely.
-
-```js
-var readable = getReadableStreamSomehow();
-var writable = fs.createWriteStream('file.txt');
-// All the data from readable goes into 'file.txt'
-readable.pipe(writable);
-```
-
-This function returns the destination stream, so you can set up pipe
-chains like so:
-
-```js
-var r = fs.createReadStream('file.txt');
-var z = zlib.createGzip();
-var w = fs.createWriteStream('file.txt.gz');
-r.pipe(z).pipe(w);
-```
-
-For example, emulating the Unix `cat` command:
-
-```js
-process.stdin.pipe(process.stdout);
-```
-
-By default [`stream.end()`][stream-end] is called on the destination when the
-source stream emits [`'end'`][], so that `destination` is no longer writable.
-Pass `{ end: false }` as `options` to keep the destination stream open.
-
-This keeps `writer` open so that "Goodbye" can be written at the
-end.
-
-```js
-reader.pipe(writer, { end: false });
-reader.on('end', () => {
-  writer.end('Goodbye\n');
-});
-```
-
-Note that [`process.stderr`][] and [`process.stdout`][] are never closed until
-the process exits, regardless of the specified options.
-
-#### readable.read([size])
-
-* `size` {Number} Optional argument to specify how much data to read.
-* Return {String|Buffer|Null}
-
-The `read()` method pulls some data out of the internal buffer and
-returns it. If there is no data available, then it will return
-`null`.
-
-If you pass in a `size` argument, then it will return that many
-bytes. If `size` bytes are not available, then it will return `null`,
-unless we've ended, in which case it will return the data remaining
-in the buffer.
-
-If you do not specify a `size` argument, then it will return all the
-data in the internal buffer.
-
-This method should only be called in paused mode. In flowing mode,
-this method is called automatically until the internal buffer is
-drained.
-
-```js
-var readable = getReadableStreamSomehow();
-readable.on('readable', () => {
-  var chunk;
-  while (null !== (chunk = readable.read())) {
-    console.log('got %d bytes of data', chunk.length);
-  }
-});
-```
-
-If this method returns a data chunk, then it will also trigger the
-emission of a [`'data'`][] event.
-
-Note that calling [`stream.read([size])`][stream-read] after the [`'end'`][]
-event has been triggered will return `null`. No runtime error will be raised.
-
-#### readable.resume()
-
-* Return: `this`
-
-This method will cause the readable stream to resume emitting [`'data'`][]
-events.
-
-This method will switch the stream into flowing mode. If you do *not*
-want to consume the data from a stream, but you *do* want to get to
-its [`'end'`][] event, you can call [`stream.resume()`][stream-resume] to open
-the flow of data.
-
-```js
-var readable = getReadableStreamSomehow();
-readable.resume();
-readable.on('end', () => {
-  console.log('got to the end, but did not read anything');
-});
-```
-
-#### readable.setEncoding(encoding)
-
-* `encoding` {String} The encoding to use.
-* Return: `this`
-
-Call this function to cause the stream to return strings of the specified
-encoding instead of Buffer objects. For example, if you do
-`readable.setEncoding('utf8')`, then the output data will be interpreted as
-UTF-8 data, and returned as strings. If you do `readable.setEncoding('hex')`,
-then the data will be encoded in hexadecimal string format.
-
-This properly handles multi-byte characters that would otherwise be
-potentially mangled if you simply pulled the Buffers directly and
-called [`buf.toString(encoding)`][] on them. If you want to read the data
-as strings, always use this method.
-
-Also you can disable any encoding at all with `readable.setEncoding(null)`.
-This approach is very useful if you deal with binary data or with large
-multi-byte strings spread out over multiple chunks.
-
-```js
-var readable = getReadableStreamSomehow();
-readable.setEncoding('utf8');
-readable.on('data', (chunk) => {
-  assert.equal(typeof chunk, 'string');
-  console.log('got %d characters of string data', chunk.length);
-});
-```
-
-#### readable.unpipe([destination])
-
-* `destination` {stream.Writable} Optional specific stream to unpipe
-
-This method will remove the hooks set up for a previous [`stream.pipe()`][]
-call.
-
-If the destination is not specified, then all pipes are removed.
-
-If the destination is specified, but no pipe is set up for it, then
-this is a no-op.
-
-```js
-var readable = getReadableStreamSomehow();
-var writable = fs.createWriteStream('file.txt');
-// All the data from readable goes into 'file.txt',
-// but only for the first second
-readable.pipe(writable);
-setTimeout(() => {
-  console.log('stop writing to file.txt');
-  readable.unpipe(writable);
-  console.log('manually close the file stream');
-  writable.end();
-}, 1000);
-```
-
-#### readable.unshift(chunk)
-
-* `chunk` {Buffer|String} Chunk of data to unshift onto the read queue
-
-This is useful in certain cases where a stream is being consumed by a
-parser, which needs to "un-consume" some data that it has
-optimistically pulled out of the source, so that the stream can be
-passed on to some other party.
-
-Note that `stream.unshift(chunk)` cannot be called after the [`'end'`][] event
-has been triggered; a runtime error will be raised.
-
-If you find that you must often call `stream.unshift(chunk)` in your
-programs, consider implementing a [Transform][] stream instead. (See [API
-for Stream Implementors][].)
-
-```js
-// Pull off a header delimited by \n\n
-// use unshift() if we get too much
-// Call the callback with (error, header, stream)
-const StringDecoder = require('string_decoder').StringDecoder;
-function parseHeader(stream, callback) {
-  stream.on('error', callback);
-  stream.on('readable', onReadable);
-  var decoder = new StringDecoder('utf8');
-  var header = '';
-  function onReadable() {
-    var chunk;
-    while (null !== (chunk = stream.read())) {
-      var str = decoder.write(chunk);
-      if (str.match(/\n\n/)) {
-        // found the header boundary
-        var split = str.split(/\n\n/);
-        header += split.shift();
-        var remaining = split.join('\n\n');
-        var buf = Buffer.from(remaining, 'utf8');
-        if (buf.length)
-          stream.unshift(buf);
-        stream.removeListener('error', callback);
-        stream.removeListener('readable', onReadable);
-        // now the body of the message can be read from the stream.
-        callback(null, header, stream);
-      } else {
-        // still reading the header.
-        header += str;
-      }
-    }
-  }
-}
-```
-
-Note that, unlike [`stream.push(chunk)`][stream-push], `stream.unshift(chunk)`
-will not end the reading process by resetting the internal reading state of the
-stream. This can cause unexpected results if `unshift()` is called during a
-read (i.e. from within a [`stream._read()`][stream-_read] implementation on a
-custom stream). Following the call to `unshift()` with an immediate
-[`stream.push('')`][stream-push] will reset the reading state appropriately,
-however it is best to simply avoid calling `unshift()` while in the process of
-performing a read.
-
-#### readable.wrap(stream)
-
-* `stream` {Stream} An "old style" readable stream
-
-Versions of Node.js prior to v0.10 had streams that did not implement the
-entire Streams API as it is today. (See [Compatibility][] for
-more information.)
-
-If you are using an older Node.js library that emits [`'data'`][] events and
-has a [`stream.pause()`][stream-pause] method that is advisory only, then you
-can use the `wrap()` method to create a [Readable][] stream that uses the old
-stream as its data source.
-
-You will very rarely ever need to call this function, but it exists
-as a convenience for interacting with old Node.js programs and libraries.
-
-For example:
-
-```js
-const OldReader = require('./old-api-module.js').OldReader;
-const Readable = require('stream').Readable;
-const oreader = new OldReader;
-const myReader = new Readable().wrap(oreader);
-
-myReader.on('readable', () => {
-  myReader.read(); // etc.
-});
-```
-
-### Class: stream.Transform
-
-Transform streams are [Duplex][] streams where the output is in some way
-computed from the input. They implement both the [Readable][] and
-[Writable][] interfaces.
-
-Examples of Transform streams include:
-
-* [zlib streams][zlib]
-* [crypto streams][crypto]
-
-### Class: stream.Writable
-
-<!--type=class-->
-
-The Writable stream interface is an abstraction for a *destination*
-that you are writing data *to*.
-
-Examples of writable streams include:
-
-* [HTTP requests, on the client][]
-* [HTTP responses, on the server][]
-* [fs write streams][]
-* [zlib streams][zlib]
-* [crypto streams][crypto]
-* [TCP sockets][]
-* [child process stdin][]
-* [`process.stdout`][], [`process.stderr`][]
-
-#### Event: 'close'
-
-Emitted when the stream and any of its underlying resources (a file descriptor,
-for example) have been closed. The event indicates that no more events will be
-emitted, and no further computation will occur.
-
-Not all streams will emit the `'close'` event as the `'close'` event is
-optional.
-
-#### Event: 'drain'
-
-If a [`stream.write(chunk)`][stream-write] call returns `false`, then the
-`'drain'` event will indicate when it is appropriate to begin writing more data
-to the stream.
-
-```js
-// Write the data to the supplied writable stream one million times.
-// Be attentive to back-pressure.
-function writeOneMillionTimes(writer, data, encoding, callback) {
-  var i = 1000000;
-  write();
-  function write() {
-    var ok = true;
-    do {
-      i -= 1;
-      if (i === 0) {
-        // last time!
-        writer.write(data, encoding, callback);
-      } else {
-        // see if we should continue, or wait
-        // don't pass the callback, because we're not done yet.
-        ok = writer.write(data, encoding);
-      }
-    } while (i > 0 && ok);
-    if (i > 0) {
-      // had to stop early!
-      // write some more once it drains
-      writer.once('drain', write);
-    }
-  }
-}
-```
-
-#### Event: 'error'
-
-* {Error}
-
-Emitted if there was an error when writing or piping data.
-
-#### Event: 'finish'
-
-When the [`stream.end()`][stream-end] method has been called, and all data has
-been flushed to the underlying system, this event is emitted.
-
-```javascript
-var writer = getWritableStreamSomehow();
-for (var i = 0; i < 100; i ++) {
-  writer.write('hello, #${i}!\n');
-}
-writer.end('this is the end\n');
-writer.on('finish', () => {
-  console.error('all writes are now complete.');
-});
-```
-
-#### Event: 'pipe'
-
-* `src` {stream.Readable} source stream that is piping to this writable
-
-This is emitted whenever the [`stream.pipe()`][] method is called on a readable
-stream, adding this writable to its set of destinations.
-
-```js
-var writer = getWritableStreamSomehow();
-var reader = getReadableStreamSomehow();
-writer.on('pipe', (src) => {
-  console.error('something is piping into the writer');
-  assert.equal(src, reader);
-});
-reader.pipe(writer);
-```
-
-#### Event: 'unpipe'
-
-* `src` {[Readable][] Stream} The source stream that
-  [unpiped][`stream.unpipe()`] this writable
-
-This is emitted whenever the [`stream.unpipe()`][] method is called on a
-readable stream, removing this writable from its set of destinations.
-
-```js
-var writer = getWritableStreamSomehow();
-var reader = getReadableStreamSomehow();
-writer.on('unpipe', (src) => {
-  console.error('something has stopped piping into the writer');
-  assert.equal(src, reader);
-});
-reader.pipe(writer);
-reader.unpipe(writer);
-```
-
-#### writable.cork()
-
-Forces buffering of all writes.
-
-Buffered data will be flushed either at [`stream.uncork()`][] or at
-[`stream.end()`][stream-end] call.
-
-#### writable.end([chunk][, encoding][, callback])
-
-* `chunk` {String|Buffer} Optional data to write
-* `encoding` {String} The encoding, if `chunk` is a String
-* `callback` {Function} Optional callback for when the stream is finished
-
-Call this method when no more data will be written to the stream. If supplied,
-the callback is attached as a listener on the [`'finish'`][] event.
-
-Calling [`stream.write()`][stream-write] after calling
-[`stream.end()`][stream-end] will raise an error.
-
-```js
-// write 'hello, ' and then end with 'world!'
-var file = fs.createWriteStream('example.txt');
-file.write('hello, ');
-file.end('world!');
-// writing more now is not allowed!
-```
-
-#### writable.setDefaultEncoding(encoding)
-
-* `encoding` {String} The new default encoding
-* Return: `this`
-
-Sets the default encoding for a writable stream.
-
-#### writable.uncork()
-
-Flush all data, buffered since [`stream.cork()`][] call.
-
-#### writable.write(chunk[, encoding][, callback])
-
-* `chunk` {String|Buffer} The data to write
-* `encoding` {String} The encoding, if `chunk` is a String
-* `callback` {Function} Callback for when this chunk of data is flushed
-* Returns: {Boolean} `true` if the data was handled completely.
-
-This method writes some data to the underlying system, and calls the
-supplied callback once the data has been fully handled.  If an error
-occurs, the callback may or may not be called with the error as its
-first argument.  To detect write errors, listen for the `'error'` event.
-
-The return value indicates if you should continue writing right now.
-If the data had to be buffered internally, then it will return
-`false`. Otherwise, it will return `true`.
-
-This return value is strictly advisory. You MAY continue to write,
-even if it returns `false`. However, writes will be buffered in
-memory, so it is best not to do this excessively. Instead, wait for
-the [`'drain'`][] event before writing more data.
-
-
-## API for Stream Implementors
-
-<!--type=misc-->
-
-To implement any sort of stream, the pattern is the same:
-
-1. Extend the appropriate parent class in your own subclass. (The
-   [`util.inherits()`][] method is particularly helpful for this.)
-2. Call the appropriate parent class constructor in your constructor,
-   to be sure that the internal mechanisms are set up properly.
-3. Implement one or more specific methods, as detailed below.
-
-The class to extend and the method(s) to implement depend on the sort
-of stream class you are writing:
-
-<table>

-
-In your implementation code, it is very important to never call the methods
-described in [API for Stream Consumers][]. Otherwise, you can potentially cause
-adverse side effects in programs that consume your streaming interfaces.
-
-### Class: stream.Duplex
-
-<!--type=class-->
-
-A "duplex" stream is one that is both Readable and Writable, such as a TCP
-socket connection.
-
-Note that `stream.Duplex` is an abstract class designed to be extended
-with an underlying implementation of the [`stream._read(size)`][stream-_read]
-and [`stream._write(chunk, encoding, callback)`][stream-_write] methods as you
-would with a Readable or Writable stream class.
-
-Since JavaScript doesn't have multiple prototypal inheritance, this class
-prototypally inherits from Readable, and then parasitically from Writable. It is
-thus up to the user to implement both the low-level
-[`stream._read(n)`][stream-_read] method as well as the low-level
-[`stream._write(chunk, encoding, callback)`][stream-_write] method on extension
-duplex classes.
-
-#### new stream.Duplex(options)
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors. Also has the following fields:
-  * `allowHalfOpen` {Boolean} Default = `true`. If set to `false`, then
-    the stream will automatically end the readable side when the
-    writable side ends and vice versa.
-  * `readableObjectMode` {Boolean} Default = `false`. Sets `objectMode`
-    for readable side of the stream. Has no effect if `objectMode`
-    is `true`.
-  * `writableObjectMode` {Boolean} Default = `false`. Sets `objectMode`
-    for writable side of the stream. Has no effect if `objectMode`
-    is `true`.
-
-In classes that extend the Duplex class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-### Class: stream.PassThrough
-
-This is a trivial implementation of a [Transform][] stream that simply
-passes the input bytes across to the output. Its purpose is mainly
-for examples and testing, but there are occasionally use cases where
-it can come in handy as a building block for novel sorts of streams.
-
-### Class: stream.Readable
-
-<!--type=class-->
-
-`stream.Readable` is an abstract class designed to be extended with an
-underlying implementation of the [`stream._read(size)`][stream-_read] method.
-
-Please see [API for Stream Consumers][] for how to consume
-streams in your programs. What follows is an explanation of how to
-implement Readable streams in your programs.
-
-#### new stream.Readable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} The maximum number of bytes to store in
-    the internal buffer before ceasing to read from the underlying
-    resource. Default = `16384` (16kb), or `16` for `objectMode` streams
-  * `encoding` {String} If specified, then buffers will be decoded to
-    strings using the specified encoding. Default = `null`
-  * `objectMode` {Boolean} Whether this stream should behave
-    as a stream of objects. Meaning that [`stream.read(n)`][stream-read] returns
-    a single value instead of a Buffer of size n. Default = `false`
-  * `read` {Function} Implementation for the [`stream._read()`][stream-_read]
-    method.
-
-In classes that extend the Readable class, make sure to call the
-Readable constructor so that the buffering settings can be properly
-initialized.
-
-#### readable.\_read(size)
-
-* `size` {Number} Number of bytes to read asynchronously
-
-Note: **Implement this method, but do NOT call it directly.**
-
-This method is prefixed with an underscore because it is internal to the
-class that defines it and should only be called by the internal Readable
-class methods. All Readable stream implementations must provide a \_read
-method to fetch data from the underlying resource.
-
-When `_read()` is called, if data is available from the resource, the `_read()`
-implementation should start pushing that data into the read queue by calling
-[`this.push(dataChunk)`][stream-push]. `_read()` should continue reading from
-the resource and pushing data until push returns `false`, at which point it
-should stop reading from the resource. Only when `_read()` is called again after
-it has stopped should it start reading more data from the resource and pushing
-that data onto the queue.
-
-Note: once the `_read()` method is called, it will not be called again until
-the [`stream.push()`][stream-push] method is called.
-
-The `size` argument is advisory. Implementations where a "read" is a
-single call that returns data can use this to know how much data to
-fetch. Implementations where that is not relevant, such as TCP or
-TLS, may ignore this argument, and simply provide data whenever it
-becomes available. There is no need, for example to "wait" until
-`size` bytes are available before calling [`stream.push(chunk)`][stream-push].
-
-#### readable.push(chunk[, encoding])
-
-
-* `chunk` {Buffer|Null|String} Chunk of data to push into the read queue
-* `encoding` {String} Encoding of String chunks.  Must be a valid
-  Buffer encoding, such as `'utf8'` or `'ascii'`
-* return {Boolean} Whether or not more pushes should be performed
-
-Note: **This method should be called by Readable implementors, NOT
-by consumers of Readable streams.**
-
-If a value other than null is passed, The `push()` method adds a chunk of data
-into the queue for subsequent stream processors to consume. If `null` is
-passed, it signals the end of the stream (EOF), after which no more data
-can be written.
-
-The data added with `push()` can be pulled out by calling the
-[`stream.read()`][stream-read] method when the [`'readable'`][] event fires.
-
-This API is designed to be as flexible as possible. For example,
-you may be wrapping a lower-level source which has some sort of
-pause/resume mechanism, and a data callback. In those cases, you
-could wrap the low-level source object by doing something like this:
-
-```js
-// source is an object with readStop() and readStart() methods,
-// and an `ondata` member that gets called when it has data, and
-// an `onend` member that gets called when the data is over.
-
-util.inherits(SourceWrapper, Readable);
-
-function SourceWrapper(options) {
-  Readable.call(this, options);
-
-  this._source = getLowlevelSourceObject();
-
-  // Every time there's data, we push it into the internal buffer.
-  this._source.ondata = (chunk) => {
-    // if push() returns false, then we need to stop reading from source
-    if (!this.push(chunk))
-      this._source.readStop();
-  };
-
-  // When the source ends, we push the EOF-signaling `null` chunk
-  this._source.onend = () => {
-    this.push(null);
-  };
-}
-
-// _read will be called when the stream wants to pull more data in
-// the advisory size argument is ignored in this case.
-SourceWrapper.prototype._read = function(size) {
-  this._source.readStart();
-};
-```
-
-#### Example: A Counting Stream
-
-<!--type=example-->
-
-This is a basic example of a Readable stream. It emits the numerals
-from 1 to 1,000,000 in ascending order, and then ends.
-
-```js
-const Readable = require('stream').Readable;
-const util = require('util');
-util.inherits(Counter, Readable);
-
-function Counter(opt) {
-  Readable.call(this, opt);
-  this._max = 1000000;
-  this._index = 1;
-}
-
-Counter.prototype._read = function() {
-  var i = this._index++;
-  if (i > this._max)
-    this.push(null);
-  else {
-    var str = '' + i;
-    var buf = Buffer.from(str, 'ascii');
-    this.push(buf);
-  }
-};
-```
-
-#### Example: SimpleProtocol v1 (Sub-optimal)
-
-This is similar to the `parseHeader` function described
-[here](#stream_readable_unshift_chunk), but implemented as a custom stream.
-Also, note that this implementation does not convert the incoming data to a
-string.
-
-However, this would be better implemented as a [Transform][] stream. See
-[SimpleProtocol v2][] for a better implementation.
-
-```js
-// A parser for a simple data protocol.
-// The "header" is a JSON object, followed by 2 \n characters, and
-// then a message body.
-//
-// NOTE: This can be done more simply as a Transform stream!
-// Using Readable directly for this is sub-optimal. See the
-// alternative example below under the Transform section.
-
-const Readable = require('stream').Readable;
-const util = require('util');
-
-util.inherits(SimpleProtocol, Readable);
-
-function SimpleProtocol(source, options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(source, options);
-
-  Readable.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-
-  // source is a readable stream, such as a socket or file
-  this._source = source;
-
-  source.on('end', () => {
-    this.push(null);
-  });
-
-  // give it a kick whenever the source is readable
-  // read(0) will not consume any bytes
-  source.on('readable', () => {
-    this.read(0);
-  });
-
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype._read = function(n) {
-  if (!this._inBody) {
-    var chunk = this._source.read();
-
-    // if the source doesn't have data, we don't have data yet.
-    if (chunk === null)
-      return this.push('');
-
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-      this.push('');
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // now, because we got some extra data, unshift the rest
-      // back into the read queue so that our consumer will see it.
-      var b = chunk.slice(split);
-      this.unshift(b);
-      // calling unshift by itself does not reset the reading state
-      // of the stream; since we're inside _read, doing an additional
-      // push('') will reset the state appropriately.
-      this.push('');
-
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-    }
-  } else {
-    // from there on, just provide the data to our consumer.
-    // careful not to push(null), since that would indicate EOF.
-    var chunk = this._source.read();
-    if (chunk) this.push(chunk);
-  }
-};
-
-// Usage:
-// var parser = new SimpleProtocol(source);
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-### Class: stream.Transform
-
-A "transform" stream is a duplex stream where the output is causally
-connected in some way to the input, such as a [zlib][] stream or a
-[crypto][] stream.
-
-There is no requirement that the output be the same size as the input,
-the same number of chunks, or arrive at the same time. For example, a
-Hash stream will only ever have a single chunk of output which is
-provided when the input is ended. A zlib stream will produce output
-that is either much smaller or much larger than its input.
-
-Rather than implement the [`stream._read()`][stream-_read] and
-[`stream._write()`][stream-_write] methods, Transform classes must implement the
-[`stream._transform()`][stream-_transform] method, and may optionally
-also implement the [`stream._flush()`][stream-_flush] method. (See below.)
-
-#### new stream.Transform([options])
-
-* `options` {Object} Passed to both Writable and Readable
-  constructors. Also has the following fields:
-  * `transform` {Function} Implementation for the
-    [`stream._transform()`][stream-_transform] method.
-  * `flush` {Function} Implementation for the [`stream._flush()`][stream-_flush]
-    method.
-
-In classes that extend the Transform class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-#### Events: 'finish' and 'end'
-
-The [`'finish'`][] and [`'end'`][] events are from the parent Writable
-and Readable classes respectively. The `'finish'` event is fired after
-[`stream.end()`][stream-end] is called and all chunks have been processed by
-[`stream._transform()`][stream-_transform], `'end'` is fired after all data has
-been output which is after the callback in [`stream._flush()`][stream-_flush]
-has been called.
-
-#### transform.\_flush(callback)
-
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done flushing any remaining data.
-
-Note: **This function MUST NOT be called directly.**  It MAY be implemented
-by child classes, and if so, will be called by the internal Transform
-class methods only.
-
-In some cases, your transform operation may need to emit a bit more
-data at the end of the stream. For example, a `Zlib` compression
-stream will store up some internal state so that it can optimally
-compress the output. At the end, however, it needs to do the best it
-can with what is left, so that the data will be complete.
-
-In those cases, you can implement a `_flush()` method, which will be
-called at the very end, after all the written data is consumed, but
-before emitting [`'end'`][] to signal the end of the readable side. Just
-like with [`stream._transform()`][stream-_transform], call
-`transform.push(chunk)` zero or more times, as appropriate, and call `callback`
-when the flush operation is complete.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs. However, you **are** expected to override this method in
-your own extension classes.
-
-#### transform.\_transform(chunk, encoding, callback)
-
-* `chunk` {Buffer|String} The chunk to be transformed. Will **always**
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type. If chunk is a buffer, then this is the special
-  value - 'buffer', ignore it in this case.
-* `callback` {Function} Call this function (optionally with an error
-  argument and data) when you are done processing the supplied chunk.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Transform
-class methods only.
-
-All Transform stream implementations must provide a `_transform()`
-method to accept input and produce output.
-
-`_transform()` should do whatever has to be done in this specific
-Transform class, to handle the bytes being written, and pass them off
-to the readable portion of the interface. Do asynchronous I/O,
-process things, and so on.
-
-Call `transform.push(outputChunk)` 0 or more times to generate output
-from this input chunk, depending on how much data you want to output
-as a result of this chunk.
-
-Call the callback function only when the current chunk is completely
-consumed. Note that there may or may not be output as a result of any
-particular input chunk. If you supply a second argument to the callback
-it will be passed to the push method. In other words the following are
-equivalent:
-
-```js
-transform.prototype._transform = function (data, encoding, callback) {
-  this.push(data);
-  callback();
-};
-
-transform.prototype._transform = function (data, encoding, callback) {
-  callback(null, data);
-};
-```
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs. However, you **are** expected to override this method in
-your own extension classes.
-
-#### Example: `SimpleProtocol` parser v2
-
-The example [here](#stream_example_simpleprotocol_v1_sub_optimal) of a simple
-protocol parser can be implemented simply by using the higher level
-[Transform][] stream class, similar to the `parseHeader` and `SimpleProtocol
-v1` examples.
-
-In this example, rather than providing the input as an argument, it
-would be piped into the parser, which is a more idiomatic Node.js stream
-approach.
-
-```javascript
-const util = require('util');
-const Transform = require('stream').Transform;
-util.inherits(SimpleProtocol, Transform);
-
-function SimpleProtocol(options) {
-  if (!(this instanceof SimpleProtocol))
-    return new SimpleProtocol(options);
-
-  Transform.call(this, options);
-  this._inBody = false;
-  this._sawFirstCr = false;
-  this._rawHeader = [];
-  this.header = null;
-}
-
-SimpleProtocol.prototype._transform = function(chunk, encoding, done) {
-  if (!this._inBody) {
-    // check if the chunk has a \n\n
-    var split = -1;
-    for (var i = 0; i < chunk.length; i++) {
-      if (chunk[i] === 10) { // '\n'
-        if (this._sawFirstCr) {
-          split = i;
-          break;
-        } else {
-          this._sawFirstCr = true;
-        }
-      } else {
-        this._sawFirstCr = false;
-      }
-    }
-
-    if (split === -1) {
-      // still waiting for the \n\n
-      // stash the chunk, and try again.
-      this._rawHeader.push(chunk);
-    } else {
-      this._inBody = true;
-      var h = chunk.slice(0, split);
-      this._rawHeader.push(h);
-      var header = Buffer.concat(this._rawHeader).toString();
-      try {

-### Class: stream.Writable
-
-<!--type=class-->
-
-`stream.Writable` is an abstract class designed to be extended with an
-underlying implementation of the
-[`stream._write(chunk, encoding, callback)`][stream-_write] method.
-
-Please see [API for Stream Consumers][] for how to consume
-writable streams in your programs. What follows is an explanation of
-how to implement Writable streams in your programs.
-
-#### new stream.Writable([options])
-
-* `options` {Object}
-  * `highWaterMark` {Number} Buffer level when
-    [`stream.write()`][stream-write] starts returning `false`. Default = `16384`
-    (16kb), or `16` for `objectMode` streams.
-  * `decodeStrings` {Boolean} Whether or not to decode strings into
-    Buffers before passing them to [`stream._write()`][stream-_write].
-    Default = `true`
-  * `objectMode` {Boolean} Whether or not the
-    [`stream.write(anyObj)`][stream-write] is a valid operation. If set you can
-    write arbitrary data instead of only `Buffer` / `String` data.
-    Default = `false`
-  * `write` {Function} Implementation for the
-    [`stream._write()`][stream-_write] method.
-  * `writev` {Function} Implementation for the
-    [`stream._writev()`][stream-_writev] method.
-
-In classes that extend the Writable class, make sure to call the
-constructor so that the buffering settings can be properly
-initialized.
-
-#### writable.\_write(chunk, encoding, callback)
-
-* `chunk` {Buffer|String} The chunk to be written. Will **always**
-  be a buffer unless the `decodeStrings` option was set to `false`.
-* `encoding` {String} If the chunk is a string, then this is the
-  encoding type. If chunk is a buffer, then this is the special
-  value - 'buffer', ignore it in this case.
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunk.
-
-All Writable stream implementations must provide a
-[`stream._write()`][stream-_write] method to send data to the underlying
-resource.
-
-Note: **This function MUST NOT be called directly.**  It should be
-implemented by child classes, and called by the internal Writable
-class methods only.
-
-Call the callback using the standard `callback(error)` pattern to
-signal that the write completed successfully or with an error.
-
-If the `decodeStrings` flag is set in the constructor options, then
-`chunk` may be a string rather than a Buffer, and `encoding` will
-indicate the sort of string that it is. This is to support
-implementations that have an optimized handling for certain string
-data encodings. If you do not explicitly set the `decodeStrings`
-option to `false`, then you can safely ignore the `encoding` argument,
-and assume that `chunk` will always be a Buffer.
-
-This method is prefixed with an underscore because it is internal to
-the class that defines it, and should not be called directly by user
-programs. However, you **are** expected to override this method in
-your own extension classes.
-
-#### writable.\_writev(chunks, callback)
-
-* `chunks` {Array} The chunks to be written. Each chunk has following
-  format: `{ chunk: ..., encoding: ... }`.
-* `callback` {Function} Call this function (optionally with an error
-  argument) when you are done processing the supplied chunks.
-
-Note: **This function MUST NOT be called directly.**  It may be
-implemented by child classes, and called by the internal Writable
-class methods only.
-
-This function is completely optional to implement. In most cases it is
-unnecessary. If implemented, it will be called with all the chunks
-that are buffered in the write queue.
-
-
-## Simplified Constructor API
-
-<!--type=misc-->
-
-In simple cases there is now the added benefit of being able to construct a
-stream without inheritance.
-
-This can be done by passing the appropriate methods as constructor options:
-
-Examples:
-
-### Duplex
-
-```js
-var duplex = new stream.Duplex({
-  read: function(n) {
-    // sets this._read under the hood
-
-    // push data onto the read queue, passing null
-    // will signal the end of the stream (EOF)
-    this.push(chunk);
-  },
-  write: function(chunk, encoding, next) {
-    // sets this._write under the hood
-
-    // An optional error can be passed as the first argument
-    next()
-  }
-});
-
-// or
-
-var duplex = new stream.Duplex({
-  read: function(n) {
-    // sets this._read under the hood
-
-    // push data onto the read queue, passing null
-    // will signal the end of the stream (EOF)
-    this.push(chunk);
-  },
-  writev: function(chunks, next) {
-    // sets this._writev under the hood
-
-    // An optional error can be passed as the first argument
-    next()
-  }
-});
-```
-
-### Readable
-
-```js
-var readable = new stream.Readable({
-  read: function(n) {
-    // sets this._read under the hood
-
-    // push data onto the read queue, passing null
-    // will signal the end of the stream (EOF)
-    this.push(chunk);
-  }
-});
-```
-
-### Transform
-
-```js
-var transform = new stream.Transform({
-  transform: function(chunk, encoding, next) {
-    // sets this._transform under the hood
-
-    // generate output as many times as needed
-    // this.push(chunk);
-
-    // call when the current chunk is consumed
-    next();
-  },
-  flush: function(done) {
-    // sets this._flush under the hood
-
-    // generate output as many times as needed
-    // this.push(chunk);
-
-    done();
-  }
-});
-```
-
-### Writable
-
-```js
-var writable = new stream.Writable({
-  write: function(chunk, encoding, next) {
-    // sets this._write under the hood
-
-    // An optional error can be passed as the first argument
-    next()
-  }
-});
-
-// or
-
-var writable = new stream.Writable({
-  writev: function(chunks, next) {
-    // sets this._writev under the hood
-
-    // An optional error can be passed as the first argument
-    next()
-  }
-});
-```
-
-## Streams: Under the Hood
-
-<!--type=misc-->
-
-### Buffering
-
-<!--type=misc-->
-
-Both Writable and Readable streams will buffer data on an internal
-object which can be retrieved from `_writableState.getBuffer()` or
-`_readableState.buffer`, respectively.
-
-The amount of data that will potentially be buffered depends on the
-`highWaterMark` option which is passed into the constructor.
-
-Buffering in Readable streams happens when the implementation calls
-[`stream.push(chunk)`][stream-push]. If the consumer of the Stream does not
-call [`stream.read()`][stream-read], then the data will sit in the internal
-queue until it is consumed.
-
-Buffering in Writable streams happens when the user calls
-[`stream.write(chunk)`][stream-write] repeatedly, even when it returns `false`.
-
-The purpose of streams, especially with the [`stream.pipe()`][] method, is to
-limit the buffering of data to acceptable levels, so that sources and
-destinations of varying speed will not overwhelm the available memory.
-
-### Compatibility with Older Node.js Versions
-
-<!--type=misc-->
-
-In versions of Node.js prior to v0.10, the Readable stream interface was
-simpler, but also less powerful and less useful.
-
-* Rather than waiting for you to call the [`stream.read()`][stream-read] method,
-  [`'data'`][] events would start emitting immediately. If you needed to do
-  some I/O to decide how to handle data, then you had to store the chunks
-  in some kind of buffer so that they would not be lost.
-* The [`stream.pause()`][stream-pause] method was advisory, rather than
-  guaranteed. This meant that you still had to be prepared to receive
-  [`'data'`][] events even when the stream was in a paused state.
-
-In Node.js v0.10, the [Readable][] class was added.
-For backwards compatibility with older Node.js programs, Readable streams
-switch into "flowing mode" when a [`'data'`][] event handler is added, or
-when the [`stream.resume()`][stream-resume] method is called. The effect is
-that, even if you are not using the new [`stream.read()`][stream-read] method
-and [`'readable'`][] event, you no longer have to worry about losing
-[`'data'`][] chunks.
-
-Most programs will continue to function normally. However, this
-introduces an edge case in the following conditions:
-
-* No [`'data'`][] event handler is added.
-* The [`stream.resume()`][stream-resume] method is never called.
-* The stream is not piped to any writable destination.
-
-For example, consider the following code:
-
-```js
-// WARNING!  BROKEN!
-net.createServer((socket) => {
-
-  // we add an 'end' method, but never consume the data
-  socket.on('end', () => {
-    // It will never get here.
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-}).listen(1337);
-```
-
-In versions of Node.js prior to v0.10, the incoming message data would be
-simply discarded. However, in Node.js v0.10 and beyond,
-the socket will remain paused forever.
-
-The workaround in this situation is to call the
-[`stream.resume()`][stream-resume] method to start the flow of data:
-
-```js
-// Workaround
-net.createServer((socket) => {
-
-  socket.on('end', () => {
-    socket.end('I got your message (but didnt read it)\n');
-  });
-
-  // start the flow of data, discarding it.
-  socket.resume();
-
-}).listen(1337);
-```
-
-In addition to new Readable streams switching into flowing mode,
-pre-v0.10 style streams can be wrapped in a Readable class using the
-[`stream.wrap()`][] method.
-
-
-### Object Mode
-
-<!--type=misc-->
-
-Normally, Streams operate on Strings and Buffers exclusively.
-
-Streams that are in **object mode** can emit generic JavaScript values
-other than Buffers and Strings.
-
-A Readable stream in object mode will always return a single item from
-a call to [`stream.read(size)`][stream-read], regardless of what the size
-argument is.
-
-A Writable stream in object mode will always ignore the `encoding`
-argument to [`stream.write(data, encoding)`][stream-write].
-
-The special value `null` still retains its special value for object
-mode streams. That is, for object mode readable streams, `null` as a
-return value from [`stream.read()`][stream-read] indicates that there is no more
-data, and [`stream.push(null)`][stream-push] will signal the end of stream data
-(`EOF`).
-
-No streams in Node.js core are object mode streams. This pattern is only
-used by userland streaming libraries.
-
-You should set `objectMode` in your stream child class constructor on
-the options object. Setting `objectMode` mid-stream is not safe.
-
-For Duplex streams `objectMode` can be set exclusively for readable or
-writable side with `readableObjectMode` and `writableObjectMode`
-respectively. These options can be used to implement parsers and
-serializers with Transform streams.
-
-```js
-const util = require('util');
-const StringDecoder = require('string_decoder').StringDecoder;
-const Transform = require('stream').Transform;
-util.inherits(JSONParseStream, Transform);
-
-// Gets \n-delimited JSON string data, and emits the parsed objects
-function JSONParseStream() {
-  if (!(this instanceof JSONParseStream))
-    return new JSONParseStream();
-
-  Transform.call(this, { readableObjectMode : true });
-
-  this._buffer = '';
-  this._decoder = new StringDecoder('utf8');
-}
-
-JSONParseStream.prototype._transform = function(chunk, encoding, cb) {
-  this._buffer += this._decoder.write(chunk);
-  // split on newlines
-  var lines = this._buffer.split(/\r?\n/);
-  // keep the last partial line buffered
-  this._buffer = lines.pop();
-  for (var l = 0; l < lines.length; l++) {
-    var line = lines[l];
-    try {
-      var obj = JSON.parse(line);
-    } catch (er) {
-      this.emit('error', er);
-      return;
-    }
-    // push the parsed object out to the readable consumer
-    this.push(obj);
-  }
-  cb();
-};
-
-JSONParseStream.prototype._flush = function(cb) {
-  // Just handle any leftover
-  var rem = this._buffer.trim();
-  if (rem) {
-    try {
-      var obj = JSON.parse(rem);
-    } catch (er) {
-      this.emit('error', er);
-      return;
-    }
-    // push the parsed object out to the readable consumer
-    this.push(obj);
-  }
-  cb();
-};
-```
-
-### `stream.read(0)`
-
-There are some cases where you want to trigger a refresh of the
-underlying readable stream mechanisms, without actually consuming any
-data. In that case, you can call `stream.read(0)`, which will always
-return null.
-
-If the internal read buffer is below the `highWaterMark`, and the
-stream is not currently reading, then calling `stream.read(0)` will trigger
-a low-level [`stream._read()`][stream-_read] call.
-
-There is almost never a need to do this. However, you will see some
-cases in Node.js's internals where this is done, particularly in the
-Readable stream class internals.
-
-### `stream.push('')`
-
-Pushing a zero-byte string or Buffer (when not in [Object mode][]) has an
-interesting side effect. Because it *is* a call to
-[`stream.push()`][stream-push], it will end the `reading` process. However, it
-does *not* add any data to the readable buffer, so there's nothing for
-a user to consume.
-
-Very rarely, there are cases where you have no data to provide now,
-but the consumer of your stream (or, perhaps, another bit of your own
-code) will know when to check again, by calling [`stream.read(0)`][stream-read].
-In those cases, you *may* call `stream.push('')`.
-
-So far, the only use case for this functionality is in the
-[`tls.CryptoStream`][] class, which is deprecated in Node.js/io.js v1.0. If you
-find that you have to use `stream.push('')`, please consider another
-approach, because it almost certainly indicates that something is
-horribly wrong.

-// 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.

-===
-
-functions to make sure the new buffer methods work in older browsers.
-
-```js
-var bufferShim = require('buffer-shims');
-bufferShim.from('foo');
-bufferShim.alloc(9, 'cafeface', 'hex');
-bufferShim.allocUnsafe(15);
-bufferShim.allocUnsafeSlow(21);
-```
-
-should just use the original  in newer nodes and on older nodes uses fallbacks.
-
-Known Issues
-===
-- this does not patch the buffer object, only the constructor stuff
-- it's actually a polyfill

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

-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();
-```
