+		<h2>Library Methods</h2>
+
+		<h4><strong>formatMoney()</strong> - format any number into currency</h4>
+
+		<p>The most basic library function for formatting numbers as money values, with customisable currency symbol, precision (decimal places), and thousand/decimal separators:</p>
+		<pre class="prettyprint lang-js">// Default usage:
+accounting.formatMoney(12345678); // $12,345,678.00
+
+// European formatting (custom symbol and separators), can also use options object as second parameter:
+accounting.formatMoney(4999.99, "&euro;", 2, ".", ","); // &euro;4.999,99
+
+// Negative values can be formatted nicely:
+accounting.formatMoney(-500000, "&pound; ", 0); // &pound; -500,000
+
+// Simple `format` string allows control of symbol position (%v = value, %s = symbol):
+accounting.formatMoney(5318008, { symbol: "GBP",  format: "%v %s" }); // 5,318,008.00 GBP</pre>
+
+
+		<h4><strong>formatColumn()</strong> - format a list of values for column-display</h4>
+
+		<p>This table demonstrates how <strong>accounting.js</strong> can take a list of numbers and money-format them with padding to line up currency symbols and decimal places</p>
+		<p>In order for the padded spaces to render correctly, the containing element must be CSS styled with <code>white-space: pre</code> (pre-formatted) - otherwise the browser will squash them into single spaces.</p>
+
+		<table id="demo-table">
+			<thead>
+				<tr>
+					<th>Original Number:</th>
+					<th>With accounting.js:</th>
+					<th>Different settings:</th>
+					<th>European format:</th>
+					<th>Symbol after value:</th>
+				</tr>
+			</thead>
+			<tbody></tbody>
+		</table>
+		<pre class="prettyprint lang-js">// Format list of numbers for display:
+accounting.formatColumn([123.5, 3456.49, 777888.99, 12345678, -5432], "$ ");</pre>
+
+
+		<h4><strong>formatNumber()</strong> - format a number with custom precision and localisation</h4>
+
+		<p>The base function of the library, which takes any number or array of numbers, runs <code>accounting.unformat()</code> to remove any formatting, and returns the number(s) formatted with separated thousands and custom precision:</p>
+		<pre class="prettyprint lang-js">accounting.formatNumber(5318008); // 5,318,008
+accounting.formatNumber(9876543.21, 3, " "); // 9 876 543.210</pre>
+
+
+		<h4><strong>toFixed()</strong> - better rounding for floating point numbers</h4>
+
+		<p>Implementation of toFixed() that treats floats more like decimal values than binary, fixing inconsistent precision rounding in JavaScript (where some .05 values round up, while others round down):</p>
+		<pre class="prettyprint lang-js">(0.615).toFixed(2); // "0.61"
+accounting.toFixed(0.615, 2); // "0.62"</pre>
+
+
+		<h4><strong>unformat()</strong> - parse a value from any formatted number/currency string</h4>
+
+		<p>Takes any number and removes all currency formatting. Aliased as <code>accounting.parse()</code></p>
+		<pre class="prettyprint lang-js">accounting.unformat("&pound; 12,345,678.90 GBP"); // 12345678.9</pre>

+**accounting.js** is a tiny JavaScript library for number, money and currency parsing/formatting. It's lightweight, fully localisable, has no dependencies, and works great client-side or server-side. Use standalone or as a nodeJS/npm and AMD/requireJS module.
+
+Visit the plugin homepage for demos and documentation: **http://openexchangerates.github.io/accounting.js/**
+
+Please checkout or download the latest stable tag before using in production. [Bug reports](https://github.com/openexchangerates/accounting.js/issues) and pull requests are welcome.
+
+Maintained by [Open Exchange Rates](https://openexchangerates.org "Free reliable exchange rates/currency conversion data API") and originally by [@josscrowcroft](http://twitter.com/josscrowcroft) and other [contributors](https://github.com/openexchangerates/accounting.js/contributors).
+
+---
+
+### Works great with:
+
+* **[money.js](http://openexchangerates.github.com/money.js "JavaScript and NodeJS Currency Conversion Library")** - a tiny (1kb) standalone JavaScript currency conversion library, for web & nodeJS
+* **[Open Exchange Rates](https://openexchangerates.org "realtime and historical exchange rates/currency conversion data API")** - the free currency conversion data API
+
+---
+
+## Changelog
+
+**v0.4.1** - Alias `accounting.formatNumber()` as `accounting.format()`
+
+**v0.4** - Transferred repository to Open Exchange Rates for ongoing maintenance
+
+**v0.3.2** - Fixed package.json dependencies (should be empty object)
+
+**v0.3.0**
+* Rewrote library structure similar to underscore.js for use as a nodeJS/npm and AMD module. Use `npm install accounting` and then `var accounting = require("accounting");` in your nodeJS scripts. 
+* Also works with requireJS or any AMD module loader.
+* **unformat** now only attempts to parse the number if it's not already a valid number. 
+* `acounting.unformat` now also aliased as `acounting.parse`
+* Fixed an IE bug in the `defaults` method
+
+**v0.2.2** - Fixed same issue as \#Num: #24 in **formatNumber**; switch to Google Closure Compiler for minified version.
+
+**v0.2.1** - Fixed issue \#Num: #24 (locally-defined settings object was being modified by **formatMoney**)
+
+**v0.2**
+* Rewrote formatting system for **formatMoney** and **formatColumn** for better control of string output
+* Now supports separate formats for negative and zero values (optionally) via `accounting.settings.currency.format`
+* Internal improvements and helper methods
+
+**v0.1.4**
+* **formatMoney** recursively formats arrays
+* Added Jasmine test suite (thanks to [millermedeiros](https://github.com/millermedeiros)) and QUnit functionality/speed tests
+
+**v0.1.3**
+* Added configurable settings object for default formatting parameters.
+* Added `format` parameter to control symbol and value position (default `"%s%v"`, or [symbol][value])
+* Methods consistently accept object as 2nd parameter, matching/overriding the library defaults
+
+**v0.1.2**
+* **formatColumn** works recursively on nested arrays (e.g. `accounting.formatColumn( [[1,12,123,1234], [1234,123,12,1]] )`, returns matching array with inner columns lined up)
+* Fix rounding in **formatNumber**
+
+**v0.1.1**
+* Added **toFixed** method (`accounting.toFixed(value, precision)`), which treats floats more like decimals for more accurate currency rounding
+* Minified version preserves semicolons
+* Fixed `NaN` errors when no value in **unformat**
+
+**v0.1** - First version

+# Async-Limiter
+
+A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
+
+[![npm](http://img.shields.io/npm/v/async-limiter.svg?style=flat-square)](http://www.npmjs.org/async-limiter)
+[![tests](https://img.shields.io/travis/STRML/async-limiter.svg?style=flat-square&branch=master)](https://travis-ci.org/STRML/async-limiter)
+[![coverage](https://img.shields.io/coveralls/STRML/async-limiter.svg?style=flat-square&branch=master)](https://coveralls.io/r/STRML/async-limiter)
+
+This module exports a class `Limiter` that implements some of the `Array` API.
+Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
+
+## Motivation
+
+Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
+run at infinite concurrency.
+
+In this case, it is actually faster, and takes far less memory, to limit concurrency.
+
+This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
+make this module faster or lighter, but new functionality is not desired.
+
+Style should confirm to nodejs/node style.
+
+## Example
+
+``` javascript
+var Limiter = require('async-limiter')
+
+var t = new Limiter({concurrency: 2});
+var results = []
+
+// add jobs using the familiar Array API
+t.push(function (cb) {
+  results.push('two')
+  cb()
+})
+
+t.push(
+  function (cb) {
+    results.push('four')
+    cb()
+  },
+  function (cb) {
+    results.push('five')
+    cb()
+  }
+)
+
+t.unshift(function (cb) {
+  results.push('one')
+  cb()
+})
+
+t.splice(2, 0, function (cb) {
+  results.push('three')
+  cb()
+})
+
+// Jobs run automatically. If you want a callback when all are done,
+// call 'onDone()'.
+t.onDone(function () {
+  console.log('all done:', results)
+})
+```
+
+## Zlib Example
+
+```js
+const zlib = require('zlib');
+const Limiter = require('async-limiter');
+
+const message = {some: "data"};
+const payload = new Buffer(JSON.stringify(message));
+
+// Try with different concurrency values to see how this actually
+// slows significantly with higher concurrency!
+//
+// 5:        1398.607ms
+// 10:       1375.668ms
+// Infinity: 4423.300ms
+//
+const t = new Limiter({concurrency: 5});
+function deflate(payload, cb) {
+  t.push(function(done) {
+    zlib.deflate(payload, function(err, buffer) {
+      done();
+      cb(err, buffer);
+    });
+  });
+}

+
+## Install
+
+`npm install async-limiter`
+
+## Test
+
+`npm test`
+
+## API
+
+### `var t = new Limiter([opts])`
+Constructor. `opts` may contain inital values for:
+* `t.concurrency`
+
+## Instance methods
+
+### `t.onDone(fn)`
+`fn` will be called once and only once, when the queue is empty.
+
+## Instance methods mixed in from `Array`
+Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
+### `t.push(element1, ..., elementN)`
+### `t.unshift(element1, ..., elementN)`
+### `t.splice(index , howMany[, element1[, ...[, elementN]]])`
+
+## Properties
+### `t.concurrency`
+Max number of jobs the queue should process concurrently, defaults to `Infinity`.
+
+### `t.length`
+Jobs pending + jobs to process (readonly).

+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!
+
+[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
+[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
+
+[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre  {   in{nest}   }  post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.

+base64-js
+=========
+
+`base64-js` does basic base64 encoding/decoding in pure JS.
+
+[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
+
+Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
+
+Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
+
+## install
+
+With [npm](https://npmjs.org) do:
+
+`npm install base64-js` and `var base64js = require('base64-js')`
+
+For use in web browsers do:
+
+`<script src="base64js.min.js"></script>`
+
+[Get supported base64-js with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-base64-js?utm_source=npm-base64-js&utm_medium=referral&utm_campaign=readme)
+
+## methods
+
+`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
+
+* `byteLength` - Takes a base64 string and returns length of byte array
+* `toByteArray` - Takes a base64 string and returns a byte array
+* `fromByteArray` - Takes a byte array and returns a base64 string

node_modules/bl/node_modules/readable-stream/GOVERNANCE.md

@@ -0,0 +1,136 @@
+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+```bash
+npm install --save readable-stream
+```
+
+This package is a mirror of the streams implementations in Node.js.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v10.19.0/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+## Version 3.x.x
+
+v3.x.x of `readable-stream` is a cut from Node 10. This version supports Node 6, 8, and 10, as well as evergreen browsers, IE 11 and latest Safari. The breaking changes introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/) and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
+
+1. Error codes: https://github.com/nodejs/node/pull/13310,
+   https://github.com/nodejs/node/pull/13291,
+   https://github.com/nodejs/node/pull/16589,
+   https://github.com/nodejs/node/pull/15042,
+   https://github.com/nodejs/node/pull/15665,
+   https://github.com/nodejs/readable-stream/pull/344
+2. 'readable' have precedence over flowing
+   https://github.com/nodejs/node/pull/18994
+3. make virtual methods errors consistent
+   https://github.com/nodejs/node/pull/18813
+4. updated streams error handling
+   https://github.com/nodejs/node/pull/18438
+5. writable.end should return this.
+   https://github.com/nodejs/node/pull/18780
+6. readable continues to read when push('')
+   https://github.com/nodejs/node/pull/18211
+7. add custom inspect to BufferList
+   https://github.com/nodejs/node/pull/17907
+8. always defer 'readable' with nextTick
+   https://github.com/nodejs/node/pull/17979
+
+## Version 2.x.x
+v2.x.x of `readable-stream` is a cut of the stream module from Node 8 (there have been no semver-major changes from Node 4 to 8). This version supports all Node.js versions from 0.8, as well as evergreen browsers and IE 10 & 11.
+
+### Big Thanks

+Cross-browser Testing Platform and Open Source <3 Provided by [Sauce Labs][sauce]
+
+# Usage
+
+You can swap your `require('stream')` with `require('readable-stream')`
+without any changes, if you are just using one of the main classes and
+functions.
+
+```js
+const {
+  Readable,
+  Writable,
+  Transform,
+  Duplex,
+  pipeline,
+  finished
+} = require('readable-stream')
+````
+
+Note that `require('stream')` will return `Stream`, while
+`require('readable-stream')` will return `Readable`. We discourage using
+whatever is exported directly, but rather use one of the properties as
+shown in the example above.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+// 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.

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

+# Buffer From
+
+A [ponyfill](https://ponyfill.com) for `Buffer.from`, uses native implementation if available.
+
+## Installation
+
+```sh
+npm install --save buffer-from
+```
+
+## Usage
+
+```js
+const bufferFrom = require('buffer-from')
+
+console.log(bufferFrom([1, 2, 3, 4]))
+//=> <Buffer 01 02 03 04>
+
+const arr = new Uint8Array([1, 2, 3, 4])
+console.log(bufferFrom(arr.buffer, 1, 2))
+//=> <Buffer 02 03>
+
+console.log(bufferFrom('test', 'utf8'))
+//=> <Buffer 74 65 73 74>
+
+const buf = bufferFrom('test')
+console.log(bufferFrom(buf))
+//=> <Buffer 74 65 73 74>
+```

+## API
+
+### bufferFrom(array)
+
+- `array` &lt;Array&gt;
+
+Allocates a new `Buffer` using an `array` of octets.
+
+### bufferFrom(arrayBuffer[, byteOffset[, length]])
+
+- `arrayBuffer` &lt;ArrayBuffer&gt; The `.buffer` property of a TypedArray or ArrayBuffer
+- `byteOffset` &lt;Integer&gt; Where to start copying from `arrayBuffer`. **Default:** `0`
+- `length` &lt;Integer&gt; How many bytes to copy from `arrayBuffer`. **Default:** `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a TypedArray instance, the
+newly created `Buffer` will share the same allocated memory as the TypedArray.
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+### bufferFrom(buffer)
+
+- `buffer` &lt;Buffer&gt; An existing `Buffer` to copy data from
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+### bufferFrom(string[, encoding])
+
+- `string` &lt;String&gt; A string to encode.
+- `encoding` &lt;String&gt; The encoding of `string`. **Default:** `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `string`. If
+provided, the `encoding` parameter identifies the character encoding of
+`string`.
