Reorganize module loading.

We now use webpack instead of SystemJS, effectively bundling modules
into one file (plus commons chunks) for every entry point.  This results
in a much smaller extension size (almost half).  Furthermore we use
yarn/npm even for extension run-time dependencies.  This relieves us
from manually vendoring and building dependencies.  It's also easier to
understand for new developers familiar with node.

+## Quick Start

 

 ```js

+// require modules

+var fs = require('fs');

 var archiver = require('archiver');

-var archive = archiver.create('zip', {}); // or archiver('zip', {});

+

+// create a file to stream archive data to.

+var output = fs.createWriteStream(__dirname + '/example.zip');

+var archive = archiver('zip', {

+    store: true // Sets the compression method to STORE.

+});

+

+// listen for all archive data to be written

+output.on('close', function() {

+  console.log(archive.pointer() + ' total bytes');

+  console.log('archiver has been finalized and the output file descriptor has closed.');

+});

+

+// good practice to catch this error explicitly

+archive.on('error', function(err) {

+  throw err;

+});

+

+// pipe archive data to the file

+archive.pipe(output);

+

+// append a file from stream

+var file1 = __dirname + '/file1.txt';

+archive.append(fs.createReadStream(file1), { name: 'file1.txt' });

+

+// append a file from string

+archive.append('string cheese!', { name: 'file2.txt' });

+

+// append a file from buffer

+var buffer3 = new Buffer('buff it!');

+archive.append(buffer3, { name: 'file3.txt' });

+

+// append a file

+archive.file('file1.txt', { name: 'file4.txt' });

+

+// append files from a directory

+archive.directory('subdir/');

+

+// append files from a glob pattern

+archive.glob('subdir/*.txt');

+

+// finalize the archive (ie we are done appending files but streams have to finish yet)

+archive.finalize();

+# v2.3.0
+- Added support for ES2017 `async` functions.  Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an `async` function.  Previously, you had to wrap `async` functions with `asyncify`.  The caveat is that it will onyl work if `async` functions are supported nateively in your environment, transpilied implementations can't be detected.  (#1386, #1390)
+- Small doc fix (#1392)
+
+# v2.2.0
+- Added `groupBy`, and the `Series`/`Limit` equivalents, analogous to [`_.groupBy`](http://lodash.com/docs#groupBy) (#1364)
+- Fixed `transform` bug when `callback` was not passed (#1381)
+- Added note about `reflect` to `parallel` docs (#1385)
+
+# v2.1.5
+- Fix `auto` bug when function names collided with Array.prototype (#1358)
+- Improve some error messages (#1349)
+- Avoid stack overflow case in queue
+- Fixed an issue in `some`, `every` and `find` where processing would continue after the result was determined.
+- Cleanup implementations of `some`, `every` and `find`
+
+# v2.1.3
+- Make bundle size smaller
+- Create optimized hotpath for `filter` in array case.
+
 # v2.1.2
 - Fixed a stackoverflow bug with `detect`, `some`, `every` on large inputs (#1293).

 Async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript. Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install --save async`, it can also be used directly in the browser.

 /**
+ * An "async function" in the context of Async is an asynchronous function with
+ * a variable number of parameters, with the final parameter being a callback.
+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed.  The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.
+ *
+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that

+## 6.16.0 (2017-02-23)
+
+### :rocket: New Feature
+
+***ESTree*** compatibility as plugin ([#277](https://github.com/babel/babylon/pull/277)) (Daniel Tschinder)
+
+We finally introduce a new compatibility layer for ESTree. To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/)
+
+We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc.
+
+To enable `estree` mode simply add the plugin in the config:
+```json
+{
+  "plugins": [ "estree" ]
+}
+```
+
+If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned.
+
+Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew)
+
+Babylon exports a new function to parse a single expression
+
+```js
+import { parseExpression } from 'babylon';
+
+const ast = parseExpression('x || y && z', options);
+```
+
+The returned AST will only consist of the expression. The options are the same as for `parse()`
+
+Add startLine option ([#346](https://github.com/babel/babylon/pull/346)) (Raphael Mu)
+
+A new option was added to babylon allowing to change the intial linenumber for the first line which is usually `1`.
+Changing this for example to `100` will make line `1` of the input source to be marked as line `100`, line `2` as `101`, line `3` as `102`, ...
+
+Function predicate declaration ([#103](https://github.com/babel/babylon/pull/103)) (Panagiotis Vekris)
+
+Added support for function predicates which flow introduced in version 0.33.0
+
+```js
+declare function is_number(x: mixed): boolean %checks(typeof x === "number");
+```
+
+Allow imports in declare module ([#315](https://github.com/babel/babylon/pull/315)) (Daniel Tschinder)
+
+Added support for imports within module declarations which flow introduced in version 0.37.0
+
+```js
+declare module "C" {
+  import type { DT } from "D";
+  declare export type CT = { D: DT };
+}
+```
+
+### :eyeglasses: Spec Compliancy
+
+Forbid semicolons after decorators in classes ([#352](https://github.com/babel/babylon/pull/352)) (Kevin Gibbons)
+
+This example now correctly throws an error when there is a semicolon after the decorator:
+
+```js
+class A {
+@a;
+foo(){}
+}
+```
+
+Keywords are not allowed as local specifier ([#307](https://github.com/babel/babylon/pull/307)) (Daniel Tschinder)
+
+Using keywords in imports is not allowed anymore:
+
+```js
+import { default } from "foo";
+import { a as debugger } from "foo";
+```
+
+Do not allow overwritting of primitive types ([#314](https://github.com/babel/babylon/pull/314)) (Daniel Tschinder)
+
+In flow it is now forbidden to overwrite the primitve types `"any"`, `"mixed"`, `"empty"`, `"bool"`, `"boolean"`, `"number"`, `"string"`, `"void"` and `"null"` with your own type declaration.
+
+Disallow import type { type a } from … ([#305](https://github.com/babel/babylon/pull/305)) (Daniel Tschinder)
+
+The following code now correctly throws an error
+
+```js
+import type { type a } from "foo";
+```
+
+Don't parse class properties without initializers when classProperties is disabled and Flow is enabled ([#300](https://github.com/babel/babylon/pull/300)) (Andrew Levine)
+
+Ensure that you enable the `classProperties` plugin in order to enable correct parsing of class properties. Prior to this version it was possible to parse them by enabling the `flow` plugin but this was not intended the behaviour.
+
+If you enable the flow plugin you can only define the type of the class properties, but not initialize them.
+
+Fix export default async function to be FunctionDeclaration ([#324](https://github.com/babel/babylon/pull/324)) (Daniel Tschinder)
+
+Parsing the following code now returns a `FunctionDeclaration` AST node instead of `FunctionExpression`.
+
+```js
+export default async function bar() {};
+```

+## 6.15.0 (2017-01-10)
+
+### :eyeglasses: Spec Compliancy
+
+Add support for Flow shorthand import type ([#267](https://github.com/babel/babylon/pull/267)) (Jeff Morrison)
+
+This change implements flows new shorthand import syntax
+and where previously you had to write this code:
+
+```js
+import {someValue} from "blah";
+import type {someType} from "blah";
+import typeof {someOtherValue} from "blah";
+```
+
+you can now write it like this:
+
+```js
+import {
+  someValue,
+  type someType,
+  typeof someOtherValue,
+} from "blah";
+```
+
+For more information look at [this](https://github.com/facebook/flow/pull/2890) pull request.
+
+flow: allow leading pipes in all positions ([#256](https://github.com/babel/babylon/pull/256)) (Vladimir Kurchatkin)
+
+This change now allows a leading pipe everywhere types can be used:
+```js
+var f = (x): | 1 | 2 => 1;
+```
+
+Throw error when exporting non-declaration ([#241](https://github.com/babel/babylon/pull/241)) (Kai Cataldo)
+
+Previously babylon parsed the following exports, although they are not valid:
+```js
+export typeof foo;
+export new Foo();
+export function() {};
+export for (;;);
+export while(foo);
+```
+
+### :bug: Bug Fix
+
+Don't set inType flag when parsing property names ([#266](https://github.com/babel/babylon/pull/266)) (Vladimir Kurchatkin)
+
+This fixes parsing of this case:
+
+```js
+const map = {
+  [age <= 17] : 'Too young'
+};
+```
+
+Fix source location for JSXEmptyExpression nodes (fixes #248) ([#249](https://github.com/babel/babylon/pull/249)) (James Long)
+
+The following case produced an invalid AST
+```js
+<div>{/* foo */}</div>
+```
+
+Use fromCodePoint to convert high value unicode entities ([#243](https://github.com/babel/babylon/pull/243)) (Ryan Duffy)
+
+When high value unicode entities (e.g. 💩) were used in the input source code they are now correctly encoded in the resulting AST.
+

-- Added one more fallback for IE11 `Script Access Denied` error with iframes, [#165](https://github.com/zloirock/core-js/issues/165)
-
-##### 2.1.3 - 2016.02.29
-- Added fallback for [`es6-promise` package bug](https://github.com/stefanpenner/es6-promise/issues/169), [#176](https://github.com/zloirock/core-js/issues/176)
-
-##### 2.1.2 - 2016.02.29
-- Some minor `Promise` fixes:
-  - Browsers `rejectionhandled` event better HTML spec complaint
-  - Errors in unhandled rejection handlers should not cause any problems
-  - Fixed typo in feature detection
-
-##### 2.1.1 - 2016.02.22
-- Some `Promise` improvements:
-  - Feature detection:
-    - **Added detection unhandled rejection tracking support - now it's available everywhere**, [#140](https://github.com/zloirock/core-js/issues/140)
-    - Added detection `@@species` pattern support for completely correct subclassing
-    - Removed usage `Object.setPrototypeOf` from feature detection and noisy console message about it in FF
-  - `Promise.all` fixed for some very specific cases
-
-##### 2.1.0 - 2016.02.09
-- **API**:
-  - ES5 polyfills are split and logic, used in other polyfills, moved to internal modules
-    - **All entry point works in ES3 environment like IE8- without `core-js/(library/)es5`**
-    - **Added all missed single entry points for ES5 polyfills**
-    - Separated ES5 polyfills moved to the ES6 namespace. Why?
-      - Mainly, for prevent duplication features in different namespaces - logic of most required ES5 polyfills changed in ES6+:
-        - Already added changes for: `Object` statics - should accept primitives, new whitespaces lists in `String#trim`, `parse(Int|float)`, `RegExp#toString` logic, `String#split`, etc
-        - Should be changed in the future: `@@species` and `ToLength` logic in `Array` methods, `Date` parsing, `Function#bind`, etc
-        - Should not be changed only several features like `Array.isArray` and `Date.now`
-      - Some ES5 polyfills required for modern engines
-    - All old entry points should work fine, but in the next major release API can be changed
-  - `Object.getOwnPropertyDescriptors` moved to the stage 3, [January TC39 meeting](https://github.com/rwaldron/tc39-notes/blob/master/es7/2016-01/2016-01-28.md#objectgetownpropertydescriptors-to-stage-3-jordan-harband-low-priority-but-super-quick)
-  - Added `umd` option for [custom build process](https://github.com/zloirock/core-js#custom-build-from-external-scripts), [#169](https://github.com/zloirock/core-js/issues/169)
-  - Returned entry points for `Array` statics, removed in `2.0`, for compatibility with `babel` `6` and for future fixes
-- **Deprecated**:
-  - `Reflect.enumerate` deprecated and will be removed from the next major release, [January TC39 meeting](https://github.com/rwaldron/tc39-notes/blob/master/es7/2016-01/2016-01-28.md#5xix-revisit-proxy-enumerate---revisit-decision-to-exhaust-iterator)
-- **New Features**:
-  - Added [`Reflect` metadata API](https://github.com/jonathandturner/decorators/blob/master/specs/metadata.md) as a pre-strawman feature, [#152](https://github.com/zloirock/core-js/issues/152):
-    - `Reflect.defineMetadata`
-    - `Reflect.deleteMetadata`
-    - `Reflect.getMetadata`
-    - `Reflect.getMetadataKeys`
-    - `Reflect.getOwnMetadata`
-    - `Reflect.getOwnMetadataKeys`
-    - `Reflect.hasMetadata`
-    - `Reflect.hasOwnMetadata`
-    - `Reflect.metadata`
-  - Implementation / fixes `Date#toJSON`
-  - Fixes for `parseInt` and `Number.parseInt`
-  - Fixes for `parseFloat` and `Number.parseFloat`
-  - Fixes for `RegExp#toString`
-  - Fixes for `Array#sort`
-  - Fixes for `Number#toFixed`
-  - Fixes for `Number#toPrecision`
-  - Additional fixes for `String#split` (`RegExp#@@split`)
-- **Improvements**:
-  - Correct subclassing wrapped collections, `Number` and `RegExp` constructors with native class syntax
-  - Correct support `SharedArrayBuffer` and buffers from other realms in typed arrays wrappers 
-  - Additional validations for `Object.{defineProperty, getOwnPropertyDescriptor}` and `Reflect.defineProperty`
-- **Bug Fixes**:
-  - Fixed some cases `Array#lastIndexOf` with negative second argument
-
-##### 2.0.3 - 2016.01.11
-- Added fallback for V8 ~ Chrome 49 `Promise` subclassing bug causes unhandled rejection on feature detection, [#159](https://github.com/zloirock/core-js/issues/159)
-- Added fix for very specific environments with global `window === null`
-
-##### 2.0.2 - 2016.01.04
-- Temporarily removed `length` validation from `Uint8Array` constructor wrapper. Reason - [bug in `ws` module](https://github.com/websockets/ws/pull/645) (-> `socket.io`) which passes to `Buffer` constructor -> `Uint8Array` float and uses [the `V8` bug](https://code.google.com/p/v8/issues/detail?id=4552) for conversion to int (by the spec should be thrown an error). [It creates problems for many people.](https://github.com/karma-runner/karma/issues/1768) I hope, it will be returned after fixing this bug in `V8`.
-
-##### 2.0.1 - 2015.12.31
-- forced usage `Promise.resolve` polyfill in the `library` version for correct work with wrapper
-- `Object.assign` should be defined in the strict mode -> throw an error on extension non-extensible objects, [#154](https://github.com/zloirock/core-js/issues/154)

-##### 2.0.0 - 2015.12.24
-- added implementations and fixes [Typed Arrays](https://github.com/zloirock/core-js#ecmascript-6-typed-arrays)-related features
-  - `ArrayBuffer`, `ArrayBuffer.isView`, `ArrayBuffer#slice`
-  - `DataView` with all getter / setter methods
-  - `Int8Array`, `Uint8Array`, `Uint8ClampedArray`, `Int16Array`, `Uint16Array`, `Int32Array`, `Uint32Array`, `Float32Array` and `Float64Array` constructors
-  - `%TypedArray%.{for, of}`, `%TypedArray%#{copyWithin, every, fill, filter, find, findIndex, forEach, indexOf, includes, join, lastIndexOf, map, reduce, reduceRight, reverse, set, slice, some, sort, subarray, values, keys, entries, @@iterator, ...}`
-- added [`System.global`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/tc39/proposal-global), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-19.md#systemglobal-jhd)
-- added [`Error.isError`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/ljharb/proposal-is-error), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-19.md#jhd-erroriserror)
-- added [`Math.{iaddh, isubh, imulh, umulh}`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://gist.github.com/BrendanEich/4294d5c212a6d2254703)
-- `RegExp.escape` moved from the `es7` to the non-standard `core` namespace, [July TC39 meeting](https://github.com/rwaldron/tc39-notes/blob/master/es7/2015-07/july-28.md#62-regexpescape) - too slow, but it's condition of stability, [#116](https://github.com/zloirock/core-js/issues/116)
-- [`Promise`](https://github.com/zloirock/core-js#ecmascript-6-promise)
-  - some performance optimisations
-  - added basic support [`rejectionHandled` event / `onrejectionhandled` handler](https://github.com/zloirock/core-js#unhandled-rejection-tracking) to the polyfill
-  - removed usage `@@species` from `Promise.{all, race}`, [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-18.md#conclusionresolution-2)
-- some improvements [collections polyfills](https://github.com/zloirock/core-js#ecmascript-6-collections)
-  - `O(1)` and preventing possible leaks with frozen keys, [#134](https://github.com/zloirock/core-js/issues/134)
-  - correct observable state object keys
-- renamed `String#{padLeft, padRight}` -> [`String#{padStart, padEnd}`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/tc39/proposal-string-pad-start-end), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-17.md#conclusionresolution-2) (they want to rename it on each meeting?O_o), [#132](https://github.com/zloirock/core-js/issues/132)
-- added [`String#{trimStart, trimEnd}` as aliases for `String#{trimLeft, trimRight}`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/sebmarkbage/ecmascript-string-left-right-trim), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-17.md#conclusionresolution-2)
-- added [annex B HTML methods](https://github.com/zloirock/core-js#ecmascript-6-string) - ugly, but also [the part of the spec](http://www.ecma-international.org/ecma-262/6.0/#sec-string.prototype.anchor)
-- added little fix for [`Date#toString`](https://github.com/zloirock/core-js#ecmascript-6-date) - `new Date(NaN).toString()` [should be `'Invalid Date'`](http://www.ecma-international.org/ecma-262/6.0/#sec-todatestring)
-- added [`{keys, values, entries, @@iterator}` methods to DOM collections](https://github.com/zloirock/core-js#iterable-dom-collections) which should have [iterable interface](https://heycam.github.io/webidl/#idl-iterable) or should be [inherited from `Array`](https://heycam.github.io/webidl/#LegacyArrayClass) - `NodeList`, `DOMTokenList`, `MediaList`, `StyleSheetList`, `CSSRuleList`.
-- removed Mozilla `Array` generics - [deprecated and will be removed from FF](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array#Array_generic_methods), [looks like strawman is dead](http://wiki.ecmascript.org/doku.php?id=strawman:array_statics), available [alternative shim](https://github.com/plusdude/array-generics)
-- removed `core.log` module
-- CommonJS API
-  - added entry points for [virtual methods](https://github.com/zloirock/core-js#commonjs-and-prototype-methods-without-global-namespace-pollution)
-  - added entry points for [stages proposals](https://github.com/zloirock/core-js#ecmascript-7-proposals)
-  - some other minor changes
-- [custom build from external scripts](https://github.com/zloirock/core-js#custom-build-from-external-scripts) moved to the separate package for preventing problems with dependencies
-- changed `$` prefix for internal modules file names because Team Foundation Server does not support it, [#129](https://github.com/zloirock/core-js/issues/129)
-- additional fix for `SameValueZero` in V8 ~ Chromium 39-42 collections
-- additional fix for FF27 `Array` iterator
-- removed usage shortcuts for `arguments` object - old WebKit bug, [#150](https://github.com/zloirock/core-js/issues/150)
-- `{Map, Set}#forEach` non-generic, [#144](https://github.com/zloirock/core-js/issues/144)

-# debug
-
-  tiny node.js debugging utility modelled after node core's debugging technique.
-
-## Installation
-
-```bash
-$ npm install debug
-```
-
-## Usage
-
- With `debug` you simply invoke the exported function to generate your debug function, passing it a name which will determine if a noop function is returned, or a decorated `console.error`, so all of the `console` format string goodies you're used to work fine. A unique color is selected per-function for visibility.
-
-Example _app.js_:
-
-```js
-var debug = require('debug')('http')
-  , http = require('http')
-  , name = 'My App';
-
-// fake app
-
-debug('booting %s', name);
-
-http.createServer(function(req, res){
-  debug(req.method + ' ' + req.url);
-  res.end('hello\n');
-}).listen(3000, function(){
-  debug('listening');
-});
-
-// fake worker of some kind
-
-require('./worker');
-```
-
-Example _worker.js_:
-
-```js
-var debug = require('debug')('worker');
-
-setInterval(function(){
-  debug('doing some work');
-}, 1000);
-```
-
- The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
-
-  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
-
-  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
-
-#### Windows note
-
- On Windows the environment variable is set using the `set` command.
-
- ```cmd
- set DEBUG=*,-not_this
- ```
-
-Then, run the program to be debugged as usual.
-
-## Millisecond diff
-
-  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
-
-  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
-
-  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
-
-  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
-
-## Conventions
-
- If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
-
-## Wildcards
-
-  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
-
-  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
-
-## Browser support
-
-  Debug works in the browser as well, currently persisted by `localStorage`. Consider the situation shown below where you have `worker:a` and `worker:b`, and wish to debug both. Somewhere in the code on your page, include:
-
-```js
-window.myDebug = require("debug");
-```
-
-  ("debug" is a global object in the browser so we give this object a different name.) When your page is open in the browser, type the following in the console:
-
-```js
-myDebug.enable("worker:*")
-```
-
-  Refresh the page. Debug output will continue to be sent to the console until it is disabled by typing `myDebug.disable()` in the console.
-
-```js
-a = debug('worker:a');
-b = debug('worker:b');
-
-setInterval(function(){
-  a('doing some work');
-}, 1000);
-
-setInterval(function(){
-  b('doing some work');
-}, 1200);
-```
-
-#### Web Inspector Colors
-
-  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
-  option. These are WebKit web inspectors, Firefox ([since version
-  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
-  and the Firebug plugin for Firefox (any version).
-
-  Colored output looks something like:
-
-  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
-
-### stderr vs stdout
-
-You can set an alternative logging method per-namespace by overriding the `log` method on a per-namespace or globally:
-
-Example _stdout.js_:
-
-```js
-var debug = require('debug');
-var error = debug('app:error');
-
-// by default stderr is used
-error('goes to stderr!');
-
-var log = debug('app:log');
-// set this namespace to log via console.log
-log.log = console.log.bind(console); // don't forget to bind to console!
-log('goes to stdout');
-error('still goes to stderr!');
-
-// set all output to go via console.info
-// overrides all per-namespace log settings
-debug.log = console.info.bind(console);
-error('now goes to stdout via console.info');
-log('still goes to stdout, but via console.info now');
-```
-
-### Save debug output to a file
-
-You can save all debug statements to a file by piping them.
-
-Example:
-
-```bash
-$ DEBUG_FD=3 node your-app.js 3> whatever.log
-```

-> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
-
-## Install
-
-Install with [npm](https://www.npmjs.com/):
-
-```sh
-$ npm install --save is-glob
-```
-
-You might also be interested in [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
-
-## Usage
-
-```js
-var isGlob = require('is-glob');
-```
-
-**True**
-
-Patterns that have glob characters or regex patterns will return `true`:
-
-```js
-isGlob('!foo.js');
-isGlob('*.js');
-isGlob('**/abc.js');
-isGlob('abc/*.js');
-isGlob('abc/(aaa|bbb).js');
-isGlob('abc/[a-z].js');
-isGlob('abc/{a,b}.js');
-isGlob('abc/?.js');
-//=> true
-```
-
-Extglobs
-
-```js
-isGlob('abc/@(a).js');
-isGlob('abc/!(a).js');
-isGlob('abc/+(a).js');
-isGlob('abc/*(a).js');
-isGlob('abc/?(a).js');
-//=> true
-```
-
-**False**
-
-Escaped globs or extglobs return `false`:
-
-```js
-isGlob('abc/\\@(a).js');
-isGlob('abc/\\!(a).js');
-isGlob('abc/\\+(a).js');
-isGlob('abc/\\*(a).js');
-isGlob('abc/\\?(a).js');
-isGlob('\\!foo.js');
-isGlob('\\*.js');
-isGlob('\\*\\*/abc.js');
-isGlob('abc/\\*.js');
-isGlob('abc/\\(aaa|bbb).js');
-isGlob('abc/\\[a-z].js');
-isGlob('abc/\\{a,b}.js');
-isGlob('abc/\\?.js');
-//=> false
-```
-
-Patterns that do not have glob patterns return `false`:
-
-```js
-isGlob('abc.js');
-isGlob('abc/def/ghi.js');
-isGlob('foo.js');
-isGlob('abc/@.js');
-isGlob('abc/+.js');
-isGlob();
-isGlob(null);
-//=> false
-```
-
-Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
-
-```js
-isGlob(['**/*.js']);
-isGlob(['foo.js']);
-//=> false
-```

-</tr>
-<tr>
-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>
-<td>>= 0.10</td>
-</tr>
-</table>
-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
-
-The default gulp coloring using gutil.colors.<color>:
-```
-values (files, module names, etc.) = cyan
-numbers (times, counts, etc) = magenta
-```
-
-### colors
-
-Is an instance of [chalk](https://github.com/sindresorhus/chalk).
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/'));
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files) {
-  
-  }));
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});
-```

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

-## What is this?
-Read this for more info about how this plays into the grand scheme of things [https://medium.com/@eschoff/3828e8126466](https://medium.com/@eschoff/3828e8126466)
-
-## File
-
-```javascript
-var File = require('vinyl');
-
-var coffeeFile = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee",
-  contents: new Buffer("test = 123")
-});
-```
-
-### isVinyl
-When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
-
-```js
-var File = require('vinyl');
-
-var dummy = new File({stuff});
-var notAFile = {};
-
-File.isVinyl(dummy); // true
-File.isVinyl(notAFile); // false
-```
-
-### constructor(options)
-#### options.cwd
-Type: `String`<br><br>Default: `process.cwd()`
-
-#### options.base
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`<br><br>Default: `options.cwd`
-
-#### options.path
-Full path to the file.
-
-Type: `String`<br><br>Default: `undefined`
-
-#### options.history
-Path history. Has no effect if `options.path` is passed.
-
-Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
-
-#### options.stat
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`<br><br>Default: `null`
-
-#### options.contents
-File contents.
-
-Type: `Buffer, Stream, or null`<br><br>Default: `null`
-
-### isBuffer()
-Returns true if file.contents is a Buffer.
-
-### isStream()
-Returns true if file.contents is a Stream.
-
-### isNull()
-Returns true if file.contents is null.
-
-### clone([opt])
-Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
-
-If opt or opt.deep is false, custom attributes will not be deep-cloned.
-
-If opt.contents is false, it will copy file.contents Buffer's reference.
-
-### pipe(stream[, opt])
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### contents
-The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
-
-For example:
-
-```js
-if (file.isBuffer()) {
-    console.log(file.contents.toString()); // logs out the string of contents
-}
-```
-
-### path
-Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
-
-### history
-Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
-
-### relative
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee
-```
-
-### dirname
-Gets and sets path.dirname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.dirname); // /test
-
-file.dirname = '/specs';
-
-console.log(file.dirname); // /specs
-console.log(file.path); // /specs/file.coffee
-`
-```
-
-### basename
-Gets and sets path.basename for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.basename); // file.coffee
-
-file.basename = 'file.js';
-
-console.log(file.basename); // file.js
-console.log(file.path); // /test/file.js
-`
-```
-
-### extname
-Gets and sets path.extname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.extname); // .coffee
-
-file.extname = '.js';
-
-console.log(file.extname); // .js
-console.log(file.path); // /test/file.js
-`
-```

-## Information
-
-<table>
-<tr> 
-<td>Package</td><td>gulp-util</td>
-</tr>
-<tr>
-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>
-<td>>= 0.10</td>
-</tr>
-</table>
-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
-
-The default gulp coloring using gutil.colors.<color>:
-```
-values (files, module names, etc.) = cyan
-numbers (times, counts, etc) = magenta
-```
-
-### colors
-
-Is an instance of [chalk](https://github.com/sindresorhus/chalk).
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/'));
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files) {
-  
-  }));
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});
-```

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

-Read this for more info about how this plays into the grand scheme of things [https://medium.com/@eschoff/3828e8126466](https://medium.com/@eschoff/3828e8126466)
-
-## File
-
-```javascript
-var File = require('vinyl');
-
-var coffeeFile = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee",
-  contents: new Buffer("test = 123")
-});
-```
-
-### isVinyl
-When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
-
-```js
-var File = require('vinyl');
-
-var dummy = new File({stuff});
-var notAFile = {};
-
-File.isVinyl(dummy); // true
-File.isVinyl(notAFile); // false
-```
-
-### constructor(options)
-#### options.cwd
-Type: `String`<br><br>Default: `process.cwd()`
-
-#### options.base
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`<br><br>Default: `options.cwd`
-
-#### options.path
-Full path to the file.
-
-Type: `String`<br><br>Default: `undefined`
-
-#### options.history
-Path history. Has no effect if `options.path` is passed.
-
-Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
-
-#### options.stat
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`<br><br>Default: `null`
-
-#### options.contents
-File contents.
-
-Type: `Buffer, Stream, or null`<br><br>Default: `null`
-
-### isBuffer()
-Returns true if file.contents is a Buffer.
-
-### isStream()
-Returns true if file.contents is a Stream.
-
-### isNull()
-Returns true if file.contents is null.
-
-### clone([opt])
-Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
-
-If opt or opt.deep is false, custom attributes will not be deep-cloned.
-
-If opt.contents is false, it will copy file.contents Buffer's reference.
-
-### pipe(stream[, opt])
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### contents
-The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
-
-For example:
-
-```js
-if (file.isBuffer()) {
-    console.log(file.contents.toString()); // logs out the string of contents
-}
-```
-
-### path
-Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
-
-### history
-Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
-
-### relative
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee
-```
-
-### dirname
-Gets and sets path.dirname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.dirname); // /test
-
-file.dirname = '/specs';
-
-console.log(file.dirname); // /specs
-console.log(file.path); // /specs/file.coffee
-`
-```
-
-### basename
-Gets and sets path.basename for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.basename); // file.coffee
-
-file.basename = 'file.js';
-
-console.log(file.basename); // file.js
-console.log(file.path); // /test/file.js
-`
-```
-
-### extname
-Gets and sets path.extname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.extname); // .coffee
-
-file.extname = '.js';
-
-console.log(file.extname); // .js
-console.log(file.path); // /test/file.js
-`
-```

-## Information
-
-<table>
-<tr> 
-<td>Package</td><td>gulp-util</td>
-</tr>
-<tr>
-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>
-<td>>= 0.10</td>
-</tr>
-</table>
-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
-
-The default gulp coloring using gutil.colors.<color>:
-```
-values (files, module names, etc.) = cyan
-numbers (times, counts, etc) = magenta
-```
-
-### colors
-
-Is an instance of [chalk](https://github.com/sindresorhus/chalk).
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/'));
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files) {
-  
-  }));
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});
-```

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

-
-## File
-
-```javascript
-var File = require('vinyl');
-
-var coffeeFile = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee",
-  contents: new Buffer("test = 123")
-});
-```
-
-### isVinyl
-When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
-
-```js
-var File = require('vinyl');
-
-var dummy = new File({stuff});
-var notAFile = {};
-
-File.isVinyl(dummy); // true
-File.isVinyl(notAFile); // false
-```
-
-### constructor(options)
-#### options.cwd
-Type: `String`<br><br>Default: `process.cwd()`
-
-#### options.base
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`<br><br>Default: `options.cwd`
-
-#### options.path
-Full path to the file.
-
-Type: `String`<br><br>Default: `undefined`
-
-#### options.history
-Path history. Has no effect if `options.path` is passed.
-
-Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
-
-#### options.stat
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`<br><br>Default: `null`
-
-#### options.contents
-File contents.
-
-Type: `Buffer, Stream, or null`<br><br>Default: `null`
-
-### isBuffer()
-Returns true if file.contents is a Buffer.
-
-### isStream()
-Returns true if file.contents is a Stream.
-
-### isNull()
-Returns true if file.contents is null.
-
-### clone([opt])
-Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
-
-If opt or opt.deep is false, custom attributes will not be deep-cloned.
-
-If opt.contents is false, it will copy file.contents Buffer's reference.
-
-### pipe(stream[, opt])
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### contents
-The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
-
-For example:
-
-```js
-if (file.isBuffer()) {
-    console.log(file.contents.toString()); // logs out the string of contents
-}
-```
-
-### path
-Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
-
-### history
-Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
-
-### relative
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee
-```
-
-### dirname
-Gets and sets path.dirname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-

-</tr>
-<tr>
-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>
-<td>>= 0.10</td>
-</tr>
-</table>
-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
-
-The default gulp coloring using gutil.colors.<color>:
-```
-values (files, module names, etc.) = cyan
-numbers (times, counts, etc) = magenta
-```
-
-### colors
-
-Is an instance of [chalk](https://github.com/sindresorhus/chalk).
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/'));
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files) {
-  
-  }));
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});

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

-## What is this?
-Read this for more info about how this plays into the grand scheme of things [https://medium.com/@eschoff/3828e8126466](https://medium.com/@eschoff/3828e8126466)
-
-## File
-
-```javascript
-var File = require('vinyl');
-
-var coffeeFile = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee",
-  contents: new Buffer("test = 123")
-});
-```
-
-### isVinyl
-When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
-
-```js
-var File = require('vinyl');
-
-var dummy = new File({stuff});
-var notAFile = {};
-
-File.isVinyl(dummy); // true
-File.isVinyl(notAFile); // false
-```
-
-### constructor(options)
-#### options.cwd
-Type: `String`<br><br>Default: `process.cwd()`
-
-#### options.base
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`<br><br>Default: `options.cwd`
-
-#### options.path
-Full path to the file.
-
-Type: `String`<br><br>Default: `undefined`
-
-#### options.history
-Path history. Has no effect if `options.path` is passed.
-
-Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
-
-#### options.stat
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`<br><br>Default: `null`
-
-#### options.contents
-File contents.
-
-Type: `Buffer, Stream, or null`<br><br>Default: `null`
-
-### isBuffer()
-Returns true if file.contents is a Buffer.
-
-### isStream()
-Returns true if file.contents is a Stream.
-
-### isNull()
-Returns true if file.contents is null.
-
-### clone([opt])
-Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
-
-If opt or opt.deep is false, custom attributes will not be deep-cloned.
-
-If opt.contents is false, it will copy file.contents Buffer's reference.
-
-### pipe(stream[, opt])
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### contents
-The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
-
-For example:
-
-```js
-if (file.isBuffer()) {
-    console.log(file.contents.toString()); // logs out the string of contents
-}
-```
-
-### path
-Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
-
-### history
-Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
-
-### relative
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee
-```
-
-### dirname
-Gets and sets path.dirname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.dirname); // /test
-
-file.dirname = '/specs';
-
-console.log(file.dirname); // /specs
-console.log(file.path); // /specs/file.coffee
-`
-```
-
-### basename
-Gets and sets path.basename for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.basename); // file.coffee
-
-file.basename = 'file.js';
-
-console.log(file.basename); // file.js
-console.log(file.path); // /test/file.js
-`
-```
-
-### extname
-Gets and sets path.extname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.extname); // .coffee
-
-file.extname = '.js';
-
-console.log(file.extname); // .js
-console.log(file.path); // /test/file.js
-`
-```

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

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

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

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

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

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

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

-Default: `process.cwd()`
+var dummy = new File({stuff});
+var notAFile = {};

 ### isBuffer()
-
 Returns true if file.contents is a Buffer.
 
 ### isStream()
-
 Returns true if file.contents is a Stream.
 
 ### isNull()
-
 Returns true if file.contents is null.
 
-### clone()
+### clone([opt])
+Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
 
-Returns a new File object with all attributes cloned.
+If opt or opt.deep is false, custom attributes will not be deep-cloned.
 
-### pipe(stream[, opt])
+If opt.contents is false, it will copy file.contents Buffer's reference.
 
+### pipe(stream[, opt])
 If file.contents is a Buffer, it will write it to the stream.
 
 If file.contents is a Stream, it will pipe it to the stream.
 
 If file.contents is null, it will do nothing.
 
-If opt.end is true, the destination stream will not be ended (same as node core).
+If opt.end is false, the destination stream will not be ended (same as node core).
 
 Returns the stream.
 
 ### inspect()
-
 Returns a pretty String interpretation of the File. Useful for console.log.
 
-### relative
+### contents
+The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
+
+For example:
+
+```js
+if (file.isBuffer()) {
+    console.log(file.contents.toString()); // logs out the string of contents
+}
+```
 
+### path
+Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
+
+### history
+Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
+
+### relative
 Returns path.relative for the file base and file path.

-# xtend

-[![browser support][3]][4]
-
-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes presedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a"
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }
-```

-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
-
-The default gulp coloring using gutil.colors.<color>:
-```
-values (files, module names, etc.) = cyan
-numbers (times, counts, etc) = magenta
-```
-
-### colors
-
-Is an instance of [chalk](https://github.com/sindresorhus/chalk).
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.

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

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

-## Information
-<table><br><tr><br><td>Package</td><td>vinyl</td><br></tr><br><tr><br><td>Description</td><br><td>A virtual file format</td><br></tr><br><tr><br><td>Node Version</td><br><td>>= 0.9</td><br></tr><br></table>

-## What is this?
-Read this for more info about how this plays into the grand scheme of things [https://medium.com/@eschoff/3828e8126466](https://medium.com/@eschoff/3828e8126466)
-
-## File
-
-```javascript
-var File = require('vinyl');
-
-var coffeeFile = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee",
-  contents: new Buffer("test = 123")
-});
-```
-
-### isVinyl
-When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
-
-```js
-var File = require('vinyl');
-
-var dummy = new File({stuff});
-var notAFile = {};
-
-File.isVinyl(dummy); // true
-File.isVinyl(notAFile); // false
-```
-
-### constructor(options)
-#### options.cwd
-Type: `String`<br><br>Default: `process.cwd()`
-
-#### options.base
-Used for relative pathing. Typically where a glob starts.
-
-Type: `String`<br><br>Default: `options.cwd`
-
-#### options.path
-Full path to the file.
-
-Type: `String`<br><br>Default: `undefined`
-
-#### options.history
-Path history. Has no effect if `options.path` is passed.
-
-Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
-
-#### options.stat
-The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
-
-Type: `fs.Stats`<br><br>Default: `null`
-
-#### options.contents
-File contents.
-
-Type: `Buffer, Stream, or null`<br><br>Default: `null`
-
-### isBuffer()
-Returns true if file.contents is a Buffer.
-
-### isStream()
-Returns true if file.contents is a Stream.
-
-### isNull()
-Returns true if file.contents is null.
-
-### clone([opt])
-Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
-
-If opt or opt.deep is false, custom attributes will not be deep-cloned.
-
-If opt.contents is false, it will copy file.contents Buffer's reference.
-
-### pipe(stream[, opt])
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### contents
-The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
-
-For example:
-
-```js
-if (file.isBuffer()) {
-    console.log(file.contents.toString()); // logs out the string of contents
-}
-```
-
-### path
-Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
-
-### history
-Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
-
-### relative
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee
-```
-
-### dirname
-Gets and sets path.dirname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.dirname); // /test
-
-file.dirname = '/specs';
-
-console.log(file.dirname); // /specs
-console.log(file.path); // /specs/file.coffee
-`
-```
-
-### basename
-Gets and sets path.basename for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.basename); // file.coffee
-
-file.basename = 'file.js';
-
-console.log(file.basename); // file.js
-console.log(file.path); // /test/file.js
-`
-```
-
-### extname
-Gets and sets path.extname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.extname); // .coffee
-
-file.extname = '.js';
-
-console.log(file.extname); // .js
-console.log(file.path); // /test/file.js
-`
-```

-## Information
-
-<table>
-<tr> 
-<td>Package</td><td>gulp-util</td>
-</tr>
-<tr>
-<td>Description</td>
-<td>Utility functions for gulp plugins</td>
-</tr>
-<tr>
-<td>Node Version</td>
-<td>>= 0.10</td>
-</tr>
-</table>
-
-## Usage
-
-```javascript
-var gutil = require('gulp-util');
-
-gutil.log('stuff happened', 'Really it did', gutil.colors.magenta('123'));
-gutil.beep();
-
-gutil.replaceExtension('file.coffee', '.js'); // file.js
-
-var opt = {
-  name: 'todd',
-  file: someGulpFile
-};
-gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
-```
-
-### log(msg...)
-
-Logs stuff. Already prefixed with [gulp] and all that. If you pass in multiple arguments it will join them by a space.
-
-The default gulp coloring using gutil.colors.<color>:
-```
-values (files, module names, etc.) = cyan
-numbers (times, counts, etc) = magenta
-```
-
-### colors
-
-Is an instance of [chalk](https://github.com/sindresorhus/chalk).
-
-### replaceExtension(path, newExtension)
-
-Replaces a file extension in a path. Returns the new path.
-
-### isStream(obj)
-
-Returns true or false if an object is a stream.
-
-### isBuffer(obj)
-
-Returns true or false if an object is a Buffer.
-
-### template(string[, data])
-
-This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
-
-## new File(obj)
-
-This is just [vinyl](https://github.com/wearefractal/vinyl)
-
-```javascript
-var file = new gutil.File({
-  base: path.join(__dirname, './fixtures/'),
-  cwd: __dirname,
-  path: path.join(__dirname, './fixtures/test.coffee')
-});
-```
-
-## noop()
-
-Returns a stream that does nothing but pass data straight through.
-
-```javascript
-// gulp should be called like this :
-// $ gulp --type production
-gulp.task('scripts', function() {
-  gulp.src('src/**/*.js')
-    .pipe(concat('script.js'))
-    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
-    .pipe(gulp.dest('dist/'));
-});
-```
-
-## buffer(cb)
-
-This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
-
-Returns a stream that can be piped to.
-
-The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
-
-Callback is optional and receives two arguments: error and data
-
-```javascript
-gulp.src('stuff/*.js')
-  .pipe(gutil.buffer(function(err, files) {
-  
-  }));
-```
-
-## new PluginError(pluginName, message[, options])
-
-- pluginName should be the module name of your plugin
-- message can be a string or an existing error
-- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
-- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
-- Note that if you pass in a custom stack string you need to include the message along with that.
-- Error properties will be included in `err.toString()`. Can be omitted by including `{showProperties: false}` in the options.
-
-These are all acceptable forms of instantiation:
-
-```javascript
-var err = new gutil.PluginError('test', {
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError({
-  plugin: 'test',
-  message: 'something broke'
-});
-
-var err = new gutil.PluginError('test', 'something broke');
-
-var err = new gutil.PluginError('test', 'something broke', {showStack: true});
-
-var existingError = new Error('OMG');
-var err = new gutil.PluginError('test', existingError, {showStack: true});
-```

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

-***Node-core streams for userland***
-
-This package is a mirror of the Streams2 and Streams3 implementations in
-Node-core, including [documentation](doc/stream.markdown).
-
-If you want to guarantee a stable streams base, regardless of what version of
-Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
-
-As of version 2.0.0 **readable-stream** uses semantic versioning.

-# 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.
-
-#### 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 Object}
-
-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 = new Buffer(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: '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
-
-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.
-
-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>
-  <thead>

-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 = new Buffer(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;
-
-  var self = this;
-  source.on('end', () => {
-    self.push(null);
-  });
-
-  // give it a kick whenever the source is readable
-  // read(0) will not consume any bytes
-  source.on('readable', () => {
-    self.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 {
-        this.header = JSON.parse(header);
-      } catch (er) {
-        this.emit('error', new Error('invalid simple protocol data'));
-        return;
-      }
-      // and let them know that we are done parsing the header.
-      this.emit('header', this.header);
-
-      // now, because we got some extra data, emit this first.
-      this.push(chunk.slice(split));
-    }
-  } else {
-    // from there on, just provide the data to our consumer as-is.
-    this.push(chunk);
-  }
-  done();
-};
-
-// Usage:
-// var parser = new SimpleProtocol();
-// source.pipe(parser)
-// Now parser is a readable stream that will emit 'header'
-// with the parsed header data.
-```
-
-### 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
-

-
-## 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.

-* mathias: always flow on data – eliminates third state
-  * explore what it breaks
-
-**action items:**
-* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)

-// 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.

-# through2
-
-[![NPM](https://nodei.co/npm/through2.png?downloads&downloadRank)](https://nodei.co/npm/through2/)
-
-**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
-
-Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
-
-Note: As 2.x.x this module starts using **Streams3** instead of Stream2. To continue using a Streams2 version use `npm install through2@0` to fetch the latest version of 0.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
-
-```js
-fs.createReadStream('ex.txt')
-  .pipe(through2(function (chunk, enc, callback) {
-    for (var i = 0; i < chunk.length; i++)
-      if (chunk[i] == 97)
-        chunk[i] = 122 // swap 'a' for 'z'
-
-    this.push(chunk)
-
-    callback()
-   }))
-  .pipe(fs.createWriteStream('out.txt'))
-```
-
-Or object streams:
-
-```js
-var all = []
-
-fs.createReadStream('data.csv')
-  .pipe(csv2())
-  .pipe(through2.obj(function (chunk, enc, callback) {
-    var data = {
-        name    : chunk[0]
-      , address : chunk[3]
-      , phone   : chunk[10]
-    }
-    this.push(data)
-
-    callback()
-  }))
-  .on('data', function (data) {
-    all.push(data)
-  })
-  .on('end', function () {
-    doSomethingSpecial(all)
-  })
-```
-
-Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
-
-## API
-
-<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
-
-Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
-
-### options
-
-The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
-
-The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2({ objectMode: true, allowHalfOpen: false },
-    function (chunk, enc, cb) {
-      cb(null, 'wut?') // note we can use the second argument on the callback
-                       // to provide data as an alternative to this.push('wut?')
-    }
-  )
-  .pipe(fs.createWriteStream('/tmp/wut.txt'))
-```
-
-### transformFunction
-
-The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
-
-To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
-
-Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
-
-If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
-
-### flushFunction
-
-The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2(
-    function (chunk, enc, cb) { cb(null, chunk) }, // transform is a noop
-    function (cb) { // flush function
-      this.push('tacking on an extra buffer to the end');
-      cb();
-    }
-  ))
-  .pipe(fs.createWriteStream('/tmp/wut.txt'));
-```
-
-<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
-
-Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
-
-```js
-var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
-  if (record.temp != null && record.unit == "F") {
-    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
-    record.unit = "C"
-  }
-  this.push(record)
-  callback()
-})
-
-// Create instances of FToC like so:
-var converter = new FToC()
-// Or:
-var converter = FToC()
-// Or specify/override options when you instantiate, if you prefer:
-var converter = FToC({objectMode: true})
-```

-File contents.
-
-Type: `Buffer, Stream, or null`<br><br>Default: `null`
-
-### isBuffer()
-Returns true if file.contents is a Buffer.
-
-### isStream()
-Returns true if file.contents is a Stream.
-
-### isNull()
-Returns true if file.contents is null.
-
-### clone([opt])
-Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
-
-If opt or opt.deep is false, custom attributes will not be deep-cloned.
-
-If opt.contents is false, it will copy file.contents Buffer's reference.
-
-### pipe(stream[, opt])
-If file.contents is a Buffer, it will write it to the stream.
-
-If file.contents is a Stream, it will pipe it to the stream.
-
-If file.contents is null, it will do nothing.
-
-If opt.end is false, the destination stream will not be ended (same as node core).
-
-Returns the stream.
-
-### inspect()
-Returns a pretty String interpretation of the File. Useful for console.log.
-
-### contents
-The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
-
-For example:
-
-```js
-if (file.isBuffer()) {
-    console.log(file.contents.toString()); // logs out the string of contents
-}
-```
-
-### path
-Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
-
-### history
-Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
-
-### relative
-Returns path.relative for the file base and file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.relative); // file.coffee
-```
-
-### dirname
-Gets and sets path.dirname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.dirname); // /test
-
-file.dirname = '/specs';
-
-console.log(file.dirname); // /specs
-console.log(file.path); // /specs/file.coffee
-`
-```
-
-### basename
-Gets and sets path.basename for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.basename); // file.coffee
-
-file.basename = 'file.js';
-
-console.log(file.basename); // file.js
-console.log(file.path); // /test/file.js
-`
-```
-
-### extname
-Gets and sets path.extname for the file path.
-
-Example:
-
-```javascript
-var file = new File({
-  cwd: "/",
-  base: "/test/",
-  path: "/test/file.coffee"
-});
-
-console.log(file.extname); // .coffee
-
-file.extname = '.js';
-
-console.log(file.extname); // .js
-console.log(file.path); // /test/file.js
-`
-```

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

-semver(1) -- The semantic versioner for npm
-===========================================
-
-## Usage
-
-    $ npm install semver
-    $ node
-    var semver = require('semver')
-
-    semver.valid('1.2.3') // '1.2.3'
-    semver.valid('a.b.c') // null
-    semver.clean('  =v1.2.3   ') // '1.2.3'
-    semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
-    semver.gt('1.2.3', '9.8.7') // false
-    semver.lt('1.2.3', '9.8.7') // true
-
-As a command-line utility:
-
-    $ semver -h
-
-    SemVer 5.1.0
-
-    A JavaScript implementation of the http://semver.org/ specification
-    Copyright Isaac Z. Schlueter
-
-    Usage: semver [options] <version> [<version> [...]]
-    Prints valid versions sorted by SemVer precedence
-
-    Options:
-    -r --range <range>
-            Print versions that match the specified range.
-
-    -i --increment [<level>]
-            Increment a version by the specified level.  Level can
-            be one of: major, minor, patch, premajor, preminor,
-            prepatch, or prerelease.  Default level is 'patch'.
-            Only one version may be specified.
-
-    --preid <identifier>
-            Identifier to be used to prefix premajor, preminor,
-            prepatch or prerelease version increments.
-
-    -l --loose
-            Interpret versions and ranges loosely
-
-    Program exits successfully if any valid version satisfies
-    all supplied ranges, and prints all satisfying versions.
-
-    If no satisfying versions are found, then exits failure.
-
-    Versions are printed in ascending order, so supplying
-    multiple versions to the utility will just sort them.
-
-## Versions
-
-A "version" is described by the `v2.0.0` specification found at
-<http://semver.org/>.
-
-A leading `"="` or `"v"` character is stripped off and ignored.
-
-## Ranges
-
-A `version range` is a set of `comparators` which specify versions
-that satisfy the range.
-
-A `comparator` is composed of an `operator` and a `version`.  The set
-of primitive `operators` is:
-
-* `<` Less than
-* `<=` Less than or equal to
-* `>` Greater than
-* `>=` Greater than or equal to
-* `=` Equal.  If no operator is specified, then equality is assumed,
-  so this operator is optional, but MAY be included.
-
-For example, the comparator `>=1.2.7` would match the versions
-`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
-or `1.1.0`.
-
-Comparators can be joined by whitespace to form a `comparator set`,
-which is satisfied by the **intersection** of all of the comparators
-it includes.
-
-A range is composed of one or more comparator sets, joined by `||`.  A
-version matches a range if and only if every comparator in at least
-one of the `||`-separated comparator sets is satisfied by the version.
-
-For example, the range `>=1.2.7 <1.3.0` would match the versions
-`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
-or `1.1.0`.
-
-The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
-`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
-
-### Prerelease Tags
-
-If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
-it will only be allowed to satisfy comparator sets if at least one
-comparator with the same `[major, minor, patch]` tuple also has a
-prerelease tag.
-
-For example, the range `>1.2.3-alpha.3` would be allowed to match the
-version `1.2.3-alpha.7`, but it would *not* be satisfied by
-`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
-than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
-range only accepts prerelease tags on the `1.2.3` version.  The
-version `3.4.5` *would* satisfy the range, because it does not have a
-prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
-
-The purpose for this behavior is twofold.  First, prerelease versions
-frequently are updated very quickly, and contain many breaking changes
-that are (by the author's design) not yet fit for public consumption.
-Therefore, by default, they are excluded from range matching
-semantics.
-
-Second, a user who has opted into using a prerelease version has
-clearly indicated the intent to use *that specific* set of
-alpha/beta/rc versions.  By including a prerelease tag in the range,
-the user is indicating that they are aware of the risk.  However, it
-is still not appropriate to assume that they have opted into taking a
-similar risk on the *next* set of prerelease versions.
-
-#### Prerelease Identifiers
-
-The method `.inc` takes an additional `identifier` string argument that
-will append the value of the string as a prerelease identifier:
-
-```javascript
-> semver.inc('1.2.3', 'prerelease', 'beta')
-'1.2.4-beta.0'
-```
-
-command-line example:
-
-```shell
-$ semver 1.2.3 -i prerelease --preid beta
-1.2.4-beta.0
-```
-
-Which then can be used to increment further:
-
-```shell
-$ semver 1.2.4-beta.0 -i prerelease
-1.2.4-beta.1
-```
-
-### Advanced Range Syntax
-
-Advanced range syntax desugars to primitive comparators in
-deterministic ways.
-
-Advanced ranges may be combined in the same way as primitive
-comparators using white space or `||`.
-
-#### Hyphen Ranges `X.Y.Z - A.B.C`
-
-Specifies an inclusive set.
-
-* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
-
-If a partial version is provided as the first version in the inclusive
-range, then the missing pieces are replaced with zeroes.
-
-* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
-
-If a partial version is provided as the second version in the
-inclusive range, then all versions that start with the supplied parts
-of the tuple are accepted, but nothing that would be greater than the
-provided tuple parts.
-
-* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
-* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
-
-#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
-
-Any of `X`, `x`, or `*` may be used to "stand in" for one of the
-numeric values in the `[major, minor, patch]` tuple.
-
-* `*` := `>=0.0.0` (Any version satisfies)
-* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
-* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
-
-A partial version range is treated as an X-Range, so the special
-character is in fact optional.
-
-* `""` (empty string) := `*` := `>=0.0.0`
-* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
-* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
-
-#### Tilde Ranges `~1.2.3` `~1.2` `~1`
-
-Allows patch-level changes if a minor version is specified on the
-comparator.  Allows minor-level changes if not.
-
-* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
-* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
-* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
-* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
-* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
-* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
-* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
-  the `1.2.3` version will be allowed, if they are greater than or
-  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
-  `1.2.4-beta.2` would not, because it is a prerelease of a
-  different `[major, minor, patch]` tuple.
-
-#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
-
-Allows changes that do not modify the left-most non-zero digit in the
-`[major, minor, patch]` tuple.  In other words, this allows patch and
-minor updates for versions `1.0.0` and above, patch updates for
-versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
-
-Many authors treat a `0.x` version as if the `x` were the major
-"breaking-change" indicator.
-
-Caret ranges are ideal when an author may make breaking changes
-between `0.2.4` and `0.3.0` releases, which is a common practice.
-However, it presumes that there will *not* be breaking changes between
-`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
-additive (but non-breaking), according to commonly observed practices.
-
-* `^1.2.3` := `>=1.2.3 <2.0.0`
-* `^0.2.3` := `>=0.2.3 <0.3.0`
-* `^0.0.3` := `>=0.0.3 <0.0.4`
-* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
-  the `1.2.3` version will be allowed, if they are greater than or
-  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
-  `1.2.4-beta.2` would not, because it is a prerelease of a
-  different `[major, minor, patch]` tuple.
-* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
-  `0.0.3` version *only* will be allowed, if they are greater than or
-  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
-
-When parsing caret ranges, a missing `patch` value desugars to the
-number `0`, but will allow flexibility within that value, even if the
-major and minor versions are both `0`.
-
-* `^1.2.x` := `>=1.2.0 <2.0.0`
-* `^0.0.x` := `>=0.0.0 <0.1.0`
-* `^0.0` := `>=0.0.0 <0.1.0`
-
-A missing `minor` and `patch` values will desugar to zero, but also
-allow flexibility within those values, even if the major version is
-zero.
-
-* `^1.x` := `>=1.0.0 <2.0.0`
-* `^0.x` := `>=0.0.0 <1.0.0`
-
-### Range Grammar
-
-Putting all this together, here is a Backus-Naur grammar for ranges,
-for the benefit of parser authors:
-
-```bnf
-range-set  ::= range ( logical-or range ) *
-logical-or ::= ( ' ' ) * '||' ( ' ' ) *
-range      ::= hyphen | simple ( ' ' simple ) * | ''
-hyphen     ::= partial ' - ' partial
-simple     ::= primitive | partial | tilde | caret
-primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
-partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
-xr         ::= 'x' | 'X' | '*' | nr
-nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
-tilde      ::= '~' partial

-## Functions
-
-All methods and classes take a final `loose` boolean argument that, if
-true, will be more forgiving about not-quite-valid semver strings.
-The resulting output will always be 100% strict, of course.
-
-Strict-mode Comparators and Ranges will be strict about the SemVer
-strings that they parse.
-
-* `valid(v)`: Return the parsed version, or null if it's not valid.
-* `inc(v, release)`: Return the version incremented by the release
-  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
-  `prepatch`, or `prerelease`), or null if it's not valid
-  * `premajor` in one call will bump the version up to the next major
-    version and down to a prerelease of that major version.
-    `preminor`, and `prepatch` work the same way.
-  * If called from a non-prerelease version, the `prerelease` will work the
-    same as `prepatch`. It increments the patch version, then makes a
-    prerelease. If the input version is already a prerelease it simply
-    increments it.
-* `prerelease(v)`: Returns an array of prerelease components, or null
-  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
-* `major(v)`: Return the major version number.
-* `minor(v)`: Return the minor version number.
-* `patch(v)`: Return the patch version number.
-
-### Comparison
-
-* `gt(v1, v2)`: `v1 > v2`
-* `gte(v1, v2)`: `v1 >= v2`
-* `lt(v1, v2)`: `v1 < v2`
-* `lte(v1, v2)`: `v1 <= v2`
-* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
-  even if they're not the exact same string.  You already know how to
-  compare strings.
-* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
-* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
-  the corresponding function above.  `"==="` and `"!=="` do simple
-  string comparison, but are included for completeness.  Throws if an
-  invalid comparison string is provided.
-* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
-  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
-* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
-  in descending order when passed to `Array.sort()`.
-* `diff(v1, v2)`: Returns difference between two versions by the release type
-  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
-  or null if the versions are the same.
-
-
-### Ranges
-
-* `validRange(range)`: Return the valid range or null if it's not valid
-* `satisfies(version, range)`: Return true if the version satisfies the
-  range.
-* `maxSatisfying(versions, range)`: Return the highest version in the list
-  that satisfies the range, or `null` if none of them do.
-* `minSatisfying(versions, range)`: Return the lowest version in the list
-  that satisfies the range, or `null` if none of them do.
-* `gtr(version, range)`: Return `true` if version is greater than all the
-  versions possible in the range.
-* `ltr(version, range)`: Return `true` if version is less than all the
-  versions possible in the range.
-* `outside(version, range, hilo)`: Return true if the version is outside
-  the bounds of the range in either the high or low direction.  The
-  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
-  the function called by `gtr` and `ltr`.)
-
-Note that, since ranges may be non-contiguous, a version might not be
-greater than a range, less than a range, *or* satisfy a range!  For
-example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
-until `2.0.0`, so the version `1.2.10` would not be greater than the
-range (because `2.0.1` satisfies, which is higher), nor less than the
-range (since `1.2.8` satisfies, which is lower), and it also does not
-satisfy the range.
-
-If you want to know if a version satisfies or does not satisfy a
-range, use the `satisfies(version, range)` function.

-### Version 2.0.0 (2016-06-19) ###
-
-- Added: Support for ES2016. In other words, support for the `**` exponentiation
-  operator.
-
-These are the breaking changes:
-
-- `'**'.match(jsTokens)` no longer returns `['*', '*']`, but `['**']`.
-- `'**='.match(jsTokens)` no longer returns `['*', '*=']`, but `['**=']`.
-
-
-### Version 1.0.3 (2016-03-27) ###
-
-- Improved: Made the regex ever so slightly smaller.
-- Updated: The readme.
-
-
-### Version 1.0.2 (2015-10-18) ###
-
-- Improved: Limited npm package contents for a smaller download. Thanks to
-  @zertosh!
-
-
-### Version 1.0.1 (2015-06-20) ###
-
-- Fixed: Declared an undeclared variable.
-
-
-### Version 1.0.0 (2015-02-26) ###
-
-- Changed: Merged the 'operator' and 'punctuation' types into 'punctuator'. That
-  type is now equivalent to the Punctuator token in the ECMAScript
-  specification. (Backwards-incompatible change.)
-- Fixed: A `-` followed by a number is now correctly matched as a punctuator
-  followed by a number. It used to be matched as just a number, but there is no
-  such thing as negative number literals. (Possibly backwards-incompatible
-  change.)
-
-
-### Version 0.4.1 (2015-02-21) ###
-
-- Added: Support for the regex `u` flag.
-
-
-### Version 0.4.0 (2015-02-21) ###
-
-- Improved: `jsTokens.matchToToken` performance.
-- Added: Support for octal and binary number literals.
-- Added: Support for template strings.
-
-
-### Version 0.3.1 (2015-01-06) ###
-
-- Fixed: Support for unicode spaces. They used to be allowed in names (which is
-  very confusing), and some unicode newlines were wrongly allowed in strings and
-  regexes.
-
-
-### Version 0.3.0 (2014-12-19) ###
-
-- Changed: The `jsTokens.names` array has been replaced with the
-  `jsTokens.matchToToken` function. The capturing groups of `jsTokens` are no
-  longer part of the public API; instead use said function. See this [gist] for
-  an example. (Backwards-incompatible change.)
-- Changed: The empty string is now considered an “invalid” token, instead an
-  “empty” token (its own group). (Backwards-incompatible change.)
-- Removed: component support. (Backwards-incompatible change.)
-
-[gist]: https://gist.github.com/lydell/be49dbf80c382c473004
-
-
-### Version 0.2.0 (2014-06-19) ###
-
-- Changed: Match ES6 function arrows (`=>`) as an operator, instead of its own
-  category (“functionArrow”), for simplicity. (Backwards-incompatible change.)
-- Added: ES6 splats (`...`) are now matched as an operator (instead of three
-  punctuations). (Backwards-incompatible change.)
-
-
-### Version 0.1.0 (2014-03-08) ###
-
-- Initial release.

-`npm install js-tokens`
-
-```js
-var jsTokens = require("js-tokens")
-```
-
-
-Usage
-=====
-
-### `jsTokens` ###
-
-A regex with the `g` flag that matches JavaScript tokens.
-
-The regex _always_ matches, even invalid JavaScript and the empty string.
-
-The next match is always directly after the previous.
-
-### `var token = jsTokens.matchToToken(match)` ###
-
-Takes a `match` returned by `jsTokens.exec(string)`, and returns a `{type:
-String, value: String}` object. The following types are available:
-
-- string
-- comment
-- regex
-- number
-- name
-- punctuator
-- whitespace
-- invalid
-
-Multi-line comments and strings also have a `closed` property indicating if the
-token was closed or not (see below).
-
-Comments and strings both come in several flavors. To distinguish them, check if
-the token starts with `//`, `/*`, `'`, `"` or `` ` ``.
-
-Names are ECMAScript IdentifierNames, that is, including both identifiers and
-keywords. You may use [is-keyword-js] to tell them apart.
-
-Whitespace includes both line terminators and other whitespace.
-
-For example usage, please see this [gist].

-
-
-ECMAScript support
-==================
-
-The intention is to always support the latest stable ECMAScript version.
-
-If adding support for a newer version requires changes, a new version with a
-major verion bump will be released.
-
-Currently, [ECMAScript 2016] is supported.
-
-[ECMAScript 2016]: http://www.ecma-international.org/ecma-262/7.0/index.html
-
-
-Invalid code handling
-=====================
-
-Unterminated strings are still matched as strings. JavaScript strings cannot
-contain (unescaped) newlines, so unterminated strings simply end at the end of
-the line. Unterminated template strings can contain unescaped newlines, though,
-so they go on to the end of input.
-
-Unterminated multi-line comments are also still matched as comments. They
-simply go on to the end of the input.
-
-Unterminated regex literals are likely matched as division and whatever is
-inside the regex.
-
-Invalid ASCII characters have their own capturing group.
-
-Invalid non-ASCII characters are treated as names, to simplify the matching of
-names (except unicode spaces which are treated as whitespace).
-
-Regex literals may contain invalid regex syntax. They are still matched as
-regex literals. They may also contain repeated regex flags, to keep the regex
-simple.
-
-Strings may contain invalid escape sequences.
-
-
-Limitations
-===========
-
-Tokenizing JavaScript using regexes—in fact, _one single regex_—won’t be
-perfect. But that’s not the point either.
-
-You may compare jsTokens with [esprima] by using `esprima-compare.js`.
-See `npm run esprima-compare`!
-
-[esprima]: http://esprima.org/
-
-### Template string interpolation ###
-
-Template strings are matched as single tokens, from the starting `` ` `` to the
-ending `` ` ``, including interpolations (whose tokens are not matched
-individually).
-
-Matching template string interpolations requires recursive balancing of `{` and
-`}`—something that JavaScript regexes cannot do. Only one level of nesting is
-supported.
-
-### Division and regex literals collision ###
-
-Consider this example:
-
-```js
-var g = 9.82
-var number = bar / 2/g
-
-var regex = / 2/g
-```
-
-A human can easily understand that in the `number` line we’re dealing with
-division, and in the `regex` line we’re dealing with a regex literal. How come?
-Because humans can look at the whole code to put the `/` characters in context.
-A JavaScript regex cannot. It only sees forwards.
-
-When the `jsTokens` regex scans throught the above, it will see the following
-at the end of both the `number` and `regex` rows:
-
-```js
-/ 2/g
-```
-
-It is then impossible to know if that is a regex literal, or part of an
-expression dealing with division.
-
-Here is a similar case:
-
-```js
-foo /= 2/g
-foo(/= 2/g)
-```
-
-The first line divides the `foo` variable with `2/g`. The second line calls the
-`foo` function with the regex literal `/= 2/g`. Again, since `jsTokens` only
-sees forwards, it cannot tell the two cases apart.
-
-There are some cases where we _can_ tell division and regex literals apart,
-though.
-
-First off, we have the simple cases where there’s only one slash in the line:
-
-```js
-var foo = 2/g
-foo /= 2
-```
-
-Regex literals cannot contain newlines, so the above cases are correctly
-identified as division. Things are only problematic when there are more than
-one non-comment slash in a single line.
-
-Secondly, not every character is a valid regex flag.
-
-```js
-var number = bar / 2/e
-```
-
-The above example is also correctly identified as division, because `e` is not a
-valid regex flag. I initially wanted to future-proof by allowing `[a-zA-Z]*`
-(any letter) as flags, but it is not worth it since it increases the amount of
-ambigous cases. So only the standard `g`, `m`, `i`, `y` and `u` flags are
-allowed. This means that the above example will be identified as division as
-long as you don’t rename the `e` variable to some permutation of `gmiyu` 1 to 5
-characters long.
-
-Lastly, we can look _forward_ for information.
-
-- If the token following what looks like a regex literal is not valid after a
-  regex literal, but is valid in a division expression, then the regex literal
-  is treated as division instead. For example, a flagless regex cannot be
-  followed by a string, number or name, but all of those three can be the
-  denominator of a division.
-- Generally, if what looks like a regex literal is followed by an operator, the
-  regex literal is treated as division instead. This is because regexes are
-  seldomly used with operators (such as `+`, `*`, `&&` and `==`), but division
-  could likely be part of such an expression.
-
-Please consult the regex source and the test cases for precise information on
-when regex or division is matched (should you need to know). In short, you
-could sum it up as:
-
-If the end of a statement looks like a regex literal (even if it isn’t), it
-will be treated as one. Otherwise it should work as expected (if you write sane
-code).

-- Node/Browser compatible. Published as [`ms`](https://www.npmjs.org/package/ms) in [NPM](http://nodejs.org/download).
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
 - If a number is supplied to `ms`, a string with a unit is returned.
-- If a string that contains the number is supplied, it returns it as
-a number (e.g: it returns `100` for `'100'`).
-- If you pass a string with a number and a valid unit, the number of
-equivalent ms is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.

+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!

-semver(1) -- The semantic versioner for npm
-===========================================
-
-## Usage
-
-    $ npm install semver
-    $ node
-    var semver = require('semver')
-
-    semver.valid('1.2.3') // '1.2.3'
-    semver.valid('a.b.c') // null
-    semver.clean('  =v1.2.3   ') // '1.2.3'
-    semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
-    semver.gt('1.2.3', '9.8.7') // false
-    semver.lt('1.2.3', '9.8.7') // true
-
-As a command-line utility:
-
-    $ semver -h
-
-    SemVer 5.1.0
-
-    A JavaScript implementation of the http://semver.org/ specification
-    Copyright Isaac Z. Schlueter
-
-    Usage: semver [options] <version> [<version> [...]]
-    Prints valid versions sorted by SemVer precedence
-
-    Options:
-    -r --range <range>
-            Print versions that match the specified range.
-
-    -i --increment [<level>]
-            Increment a version by the specified level.  Level can
-            be one of: major, minor, patch, premajor, preminor,
-            prepatch, or prerelease.  Default level is 'patch'.
-            Only one version may be specified.
-
-    --preid <identifier>
-            Identifier to be used to prefix premajor, preminor,
-            prepatch or prerelease version increments.
-
-    -l --loose
-            Interpret versions and ranges loosely
-
-    Program exits successfully if any valid version satisfies
-    all supplied ranges, and prints all satisfying versions.
-
-    If no satisfying versions are found, then exits failure.
-
-    Versions are printed in ascending order, so supplying
-    multiple versions to the utility will just sort them.
-
-## Versions
-
-A "version" is described by the `v2.0.0` specification found at
-<http://semver.org/>.
-
-A leading `"="` or `"v"` character is stripped off and ignored.
-
-## Ranges
-
-A `version range` is a set of `comparators` which specify versions
-that satisfy the range.
-
-A `comparator` is composed of an `operator` and a `version`.  The set
-of primitive `operators` is:
-
-* `<` Less than
-* `<=` Less than or equal to
-* `>` Greater than
-* `>=` Greater than or equal to
-* `=` Equal.  If no operator is specified, then equality is assumed,
-  so this operator is optional, but MAY be included.
-
-For example, the comparator `>=1.2.7` would match the versions
-`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
-or `1.1.0`.
-
-Comparators can be joined by whitespace to form a `comparator set`,
-which is satisfied by the **intersection** of all of the comparators
-it includes.
-
-A range is composed of one or more comparator sets, joined by `||`.  A
-version matches a range if and only if every comparator in at least
-one of the `||`-separated comparator sets is satisfied by the version.
-
-For example, the range `>=1.2.7 <1.3.0` would match the versions
-`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
-or `1.1.0`.
-
-The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
-`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
-
-### Prerelease Tags
-
-If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
-it will only be allowed to satisfy comparator sets if at least one
-comparator with the same `[major, minor, patch]` tuple also has a
-prerelease tag.
-
-For example, the range `>1.2.3-alpha.3` would be allowed to match the
-version `1.2.3-alpha.7`, but it would *not* be satisfied by
-`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
-than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
-range only accepts prerelease tags on the `1.2.3` version.  The
-version `3.4.5` *would* satisfy the range, because it does not have a
-prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
-
-The purpose for this behavior is twofold.  First, prerelease versions
-frequently are updated very quickly, and contain many breaking changes
-that are (by the author's design) not yet fit for public consumption.
-Therefore, by default, they are excluded from range matching
-semantics.
-
-Second, a user who has opted into using a prerelease version has
-clearly indicated the intent to use *that specific* set of
-alpha/beta/rc versions.  By including a prerelease tag in the range,
-the user is indicating that they are aware of the risk.  However, it
-is still not appropriate to assume that they have opted into taking a
-similar risk on the *next* set of prerelease versions.
-
-#### Prerelease Identifiers
-
-The method `.inc` takes an additional `identifier` string argument that
-will append the value of the string as a prerelease identifier:
-
-```javascript
-> semver.inc('1.2.3', 'prerelease', 'beta')
-'1.2.4-beta.0'
-```
-
-command-line example:
-
-```shell
-$ semver 1.2.3 -i prerelease --preid beta
-1.2.4-beta.0
-```
-
-Which then can be used to increment further:
-
-```shell
-$ semver 1.2.4-beta.0 -i prerelease
-1.2.4-beta.1
-```
-
-### Advanced Range Syntax
-
-Advanced range syntax desugars to primitive comparators in
-deterministic ways.
-
-Advanced ranges may be combined in the same way as primitive
-comparators using white space or `||`.
-
-#### Hyphen Ranges `X.Y.Z - A.B.C`
-
-Specifies an inclusive set.
-
-* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
-
-If a partial version is provided as the first version in the inclusive
-range, then the missing pieces are replaced with zeroes.
-
-* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
-
-If a partial version is provided as the second version in the
-inclusive range, then all versions that start with the supplied parts
-of the tuple are accepted, but nothing that would be greater than the
-provided tuple parts.
-
-* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
-* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
-
-#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
-
-Any of `X`, `x`, or `*` may be used to "stand in" for one of the
-numeric values in the `[major, minor, patch]` tuple.
-
-* `*` := `>=0.0.0` (Any version satisfies)
-* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
-* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
-
-A partial version range is treated as an X-Range, so the special
-character is in fact optional.
-
-* `""` (empty string) := `*` := `>=0.0.0`
-* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
-* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
-
-#### Tilde Ranges `~1.2.3` `~1.2` `~1`
-
-Allows patch-level changes if a minor version is specified on the
-comparator.  Allows minor-level changes if not.
-
-* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
-* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
-* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
-* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
-* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
-* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
-* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
-  the `1.2.3` version will be allowed, if they are greater than or
-  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
-  `1.2.4-beta.2` would not, because it is a prerelease of a
-  different `[major, minor, patch]` tuple.
-
-#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
-
-Allows changes that do not modify the left-most non-zero digit in the
-`[major, minor, patch]` tuple.  In other words, this allows patch and
-minor updates for versions `1.0.0` and above, patch updates for
-versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
-
-Many authors treat a `0.x` version as if the `x` were the major
-"breaking-change" indicator.
-
-Caret ranges are ideal when an author may make breaking changes
-between `0.2.4` and `0.3.0` releases, which is a common practice.
-However, it presumes that there will *not* be breaking changes between
-`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
-additive (but non-breaking), according to commonly observed practices.
-
-* `^1.2.3` := `>=1.2.3 <2.0.0`
-* `^0.2.3` := `>=0.2.3 <0.3.0`
-* `^0.0.3` := `>=0.0.3 <0.0.4`
-* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
-  the `1.2.3` version will be allowed, if they are greater than or
-  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
-  `1.2.4-beta.2` would not, because it is a prerelease of a
-  different `[major, minor, patch]` tuple.
-* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
-  `0.0.3` version *only* will be allowed, if they are greater than or
-  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
-
-When parsing caret ranges, a missing `patch` value desugars to the
-number `0`, but will allow flexibility within that value, even if the
-major and minor versions are both `0`.
-
-* `^1.2.x` := `>=1.2.0 <2.0.0`
-* `^0.0.x` := `>=0.0.0 <0.1.0`
-* `^0.0` := `>=0.0.0 <0.1.0`
-
-A missing `minor` and `patch` values will desugar to zero, but also
-allow flexibility within those values, even if the major version is
-zero.
-
-* `^1.x` := `>=1.0.0 <2.0.0`
-* `^0.x` := `>=0.0.0 <1.0.0`
-
-### Range Grammar
-
-Putting all this together, here is a Backus-Naur grammar for ranges,
-for the benefit of parser authors:
-
-```bnf
-range-set  ::= range ( logical-or range ) *
-logical-or ::= ( ' ' ) * '||' ( ' ' ) *
-range      ::= hyphen | simple ( ' ' simple ) * | ''
-hyphen     ::= partial ' - ' partial
-simple     ::= primitive | partial | tilde | caret
-primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
-partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
-xr         ::= 'x' | 'X' | '*' | nr
-nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
-tilde      ::= '~' partial
-caret      ::= '^' partial
-qualifier  ::= ( '-' pre )? ( '+' build )?
-pre        ::= parts
-build      ::= parts
-parts      ::= part ( '.' part ) *
-part       ::= nr | [-0-9A-Za-z]+
-```
-
-## Functions
-
-All methods and classes take a final `loose` boolean argument that, if
-true, will be more forgiving about not-quite-valid semver strings.
-The resulting output will always be 100% strict, of course.
-
-Strict-mode Comparators and Ranges will be strict about the SemVer
-strings that they parse.
-
-* `valid(v)`: Return the parsed version, or null if it's not valid.
-* `inc(v, release)`: Return the version incremented by the release
-  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
-  `prepatch`, or `prerelease`), or null if it's not valid
-  * `premajor` in one call will bump the version up to the next major
-    version and down to a prerelease of that major version.
-    `preminor`, and `prepatch` work the same way.
-  * If called from a non-prerelease version, the `prerelease` will work the
-    same as `prepatch`. It increments the patch version, then makes a
-    prerelease. If the input version is already a prerelease it simply
-    increments it.
-* `prerelease(v)`: Returns an array of prerelease components, or null
-  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
-* `major(v)`: Return the major version number.
-* `minor(v)`: Return the minor version number.
-* `patch(v)`: Return the patch version number.
-
-### Comparison
-
-* `gt(v1, v2)`: `v1 > v2`
-* `gte(v1, v2)`: `v1 >= v2`
-* `lt(v1, v2)`: `v1 < v2`
-* `lte(v1, v2)`: `v1 <= v2`
-* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
-  even if they're not the exact same string.  You already know how to
-  compare strings.
-* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
-* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
-  the corresponding function above.  `"==="` and `"!=="` do simple
-  string comparison, but are included for completeness.  Throws if an
-  invalid comparison string is provided.
-* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
-  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
-* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
-  in descending order when passed to `Array.sort()`.
-* `diff(v1, v2)`: Returns difference between two versions by the release type
-  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
-  or null if the versions are the same.
-
-
-### Ranges
-
-* `validRange(range)`: Return the valid range or null if it's not valid
-* `satisfies(version, range)`: Return true if the version satisfies the
-  range.
-* `maxSatisfying(versions, range)`: Return the highest version in the list
-  that satisfies the range, or `null` if none of them do.
-* `minSatisfying(versions, range)`: Return the lowest version in the list
-  that satisfies the range, or `null` if none of them do.
-* `gtr(version, range)`: Return `true` if version is greater than all the
-  versions possible in the range.
-* `ltr(version, range)`: Return `true` if version is less than all the
-  versions possible in the range.
-* `outside(version, range, hilo)`: Return true if the version is outside
-  the bounds of the range in either the high or low direction.  The
-  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
-  the function called by `gtr` and `ltr`.)
-
-Note that, since ranges may be non-contiguous, a version might not be
-greater than a range, less than a range, *or* satisfy a range!  For
-example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
-until `2.0.0`, so the version `1.2.10` would not be greater than the
-range (because `2.0.1` satisfies, which is higher), nor less than the
-range (since `1.2.8` satisfies, which is lower), and it also does not
-satisfy the range.
-
-If you want to know if a version satisfies or does not satisfy a
-range, use the `satisfies(version, range)` function.

-# osenv
-
-Look up environment settings specific to different operating systems.
-
-## Usage
-
-```javascript
-var osenv = require('osenv')
-var path = osenv.path()
-var user = osenv.user()
-// etc.
-
-// Some things are not reliably in the env, and have a fallback command:
-var h = osenv.hostname(function (er, hostname) {
-  h = hostname
-})
-// This will still cause it to be memoized, so calling osenv.hostname()
-// is now an immediate operation.
-
-// You can always send a cb, which will get called in the nextTick
-// if it's been memoized, or wait for the fallback data if it wasn't
-// found in the environment.
-osenv.hostname(function (er, hostname) {
-  if (er) console.error('error looking up hostname')
-  else console.log('this machine calls itself %s', hostname)
-})
-```
-
-## osenv.hostname()
-
-The machine name.  Calls `hostname` if not found.
-
-## osenv.user()
-
-The currently logged-in user.  Calls `whoami` if not found.
-
-## osenv.prompt()
-
-Either PS1 on unix, or PROMPT on Windows.
-
-## osenv.tmpdir()
-
-The place where temporary files should be created.
-
-## osenv.home()
-
-No place like it.
-
-## osenv.path()
-
-An array of the places that the operating system will search for
-executables.
-
-## osenv.editor() 
-
-Return the executable name of the editor program.  This uses the EDITOR
-and VISUAL environment variables, and falls back to `vi` on Unix, or
-`notepad.exe` on Windows.
-
-## osenv.shell()
-
-The SHELL on Unix, which Windows calls the ComSpec.  Defaults to 'bash'
-or 'cmd'.

 ## Usage
@@ -70,15 +64,13 @@ randomize('Aa0!', 10);
 
 If `length` is left undefined, the length of the pattern in the first parameter will be used. For example:
 
-+ `randomize('00')` will generate a 2-digit random number
+* `randomize('00')` will generate a 2-digit random number
 * `randomize('000')` will generate a 3-digit random number
 * `randomize('0000')` will generate a 4-digit random number...
 * `randomize('AAAAA')` will generate a 5-character, uppercase alphabetical random string...
 
 These are just examples, [see the tests](./test.js) for more use cases and examples.

+
+* Added warning log messages when the user creates new managed promises, or

+
+  ```js
+  const {logging} = require('selenium-webdriver');
+  logging.installConsoleHandler();
+  logging.getLogger('promise.ControlFlow').setLevel(logging.Level.WARNING);
+  ```
+* If the `JAVA_HOME` environment variable is set, use it to locate java.exe.
+
+
+## v3.2.0
+
+* Release skipped to stay in sync with the main Selenium project.
+
+
+## v3.1.0
+
+* The `lib` package is once again platform agnostic (excluding `lib/devmode`).
+* Deprecated `promise.when(value, callback, errback)`.
+  Use `promise.fulfilled(value).then(callback, errback)`
+* Changed `promise.fulfilled(value)`, `promise.rejected(reason)` and
+  `promise.defer()` to all use native promises when the promise manager is
+  disabled.
+* Properly handle W3C error responses to new session commands.
+* Updated `selenium-webdriver/testing` to export `describe.only` along with
+  `describe.skip`.
+* Fixed `selenium-webdriver/lib/until.ableToSwitchToFrame`. It was previously
+  dropping arguments and would never work.
+* Added the ability to use Firefox Nightly
+* If Firefox cannot be found in the default location, look for it on the PATH
+* Allow SafariDriver to use Safari Technology Preview.
+* Use the proper wire command for WebElement.getLocation() and
+  WebElement.getSize() for W3C compliant drivers.
+
+
 ## v3.0.1
 
 * More API adjustments to align with native Promises

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