+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+
+This is a large database of mime types and information about them.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+### Database Download
+
+If you're crazy enough to use this in the browser, you can just grab the
+JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
+replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
+as the JSON format may change in the future.
+
+```
+https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db')
+
+// grab data on .js files
+var data = db['application/javascript']
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom-types.json` or
+`src/custom-suffix.json`.
+
+The `src/custom-types.json` file is a JSON object with the MIME type as the
+keys and the values being an object with the following keys:
+
+- `compressible` - leave out if you don't know, otherwise `true`/`false` to
+  indicate whether the data represented by the type is typically compressible.
+- `extensions` - include an array of file extensions that are associated with
+  the type.
+- `notes` - human-readable notes about the type, typically what the type is.
+- `sources` - include an array of URLs of where the MIME type and the associated
+  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
+  links to type aggregating sites and Wikipedia are _not acceptable_.
+
+To update the build, run `npm run build`.
+
+### Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.
+
+If that is not possible / feasible, they can be added directly here as a
+"custom" type. To do this, it is required to have a primary source that
+definitively lists the media type. If an extension is going to be listed as
+associateed with this media type, the source must definitively link the
+media type and extension as well.

+
+The ultimate javascript content-type utility.
+
+Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type,
+  `mime-types` simply returns `false`, so do
+  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- No `.define()` functionality
+- Bug fixes for `.lookup(path)`
+
+Otherwise, the API is compatible with `mime` 1.x.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json') // 'application/json'

+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+When given an extension, `mime.lookup` is used to get the matching
+content-type, otherwise the given content-type is used. Then if the
+content-type does not already have a `charset` parameter, `mime.charset`
+is used to get the default charset and add to the returned content-type.
+
+```js
+mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+mime.contentType('text/html') // 'text/html; charset=utf-8'
+mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
+
+// from a full path
+mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]
+
+A map of extensions by content-type.

+======
+Javascript module to match a string against a regular expression, glob, string,
+or function that takes the string as an argument and returns a truthy or falsy
+value. The matcher can also be an array of any or all of these. Useful for
+allowing a very flexible user-defined config to define things like file paths.
+
+__Note: This module has Bash-parity, please be aware that Windows-style backslashes are not supported as separators. See https://github.com/micromatch/micromatch#backslashes for more information.__
+
+[![NPM](https://nodei.co/npm/anymatch.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/anymatch/)
+[![NPM](https://nodei.co/npm-dl/anymatch.png?height=3&months=9)](https://nodei.co/npm-dl/anymatch/)
+
+Usage
+-----
+```sh
+npm install anymatch --save
+```
+
+#### anymatch (matchers, testString, [returnIndex], [startIndex], [endIndex])
+* __matchers__: (_Array|String|RegExp|Function_)
+String to be directly matched, string with glob patterns, regular expression
+test, function that takes the testString as an argument and returns a truthy
+value if it should be matched, or an array of any number and mix of these types.
+* __testString__: (_String|Array_) The string to test against the matchers. If
+passed as an array, the first element of the array will be used as the
+`testString` for non-function matchers, while the entire array will be applied
+as the arguments for function matchers.
+* __returnIndex__: (_Boolean [optional]_) If true, return the array index of
+the first matcher that that testString matched, or -1 if no match, instead of a
+boolean result.
+* __startIndex, endIndex__: (_Integer [optional]_) Can be used to define a
+subset out of the array of provided matchers to test against. Can be useful
+with bound matcher functions (see below). When used with `returnIndex = true`
+preserves original indexing. Behaves the same as `Array.prototype.slice` (i.e.
+includes array members up to, but not including endIndex).
+
+```js
+var anymatch = require('anymatch');
+
+var matchers = [
+	'path/to/file.js',
+	'path/anyjs/**/*.js',
+	/foo\.js$/,
+	function (string) {
+		return string.indexOf('bar') !== -1 && string.length > 10
+	}
+];
+
+anymatch(matchers, 'path/to/file.js'); // true
+anymatch(matchers, 'path/anyjs/baz.js'); // true
+anymatch(matchers, 'path/to/foo.js'); // true
+anymatch(matchers, 'path/to/bar.js'); // true
+anymatch(matchers, 'bar.js'); // false
+
+// returnIndex = true
+anymatch(matchers, 'foo.js', true); // 2
+anymatch(matchers, 'path/anyjs/foo.js', true); // 1
+
+// skip matchers
+anymatch(matchers, 'path/to/file.js', false, 1); // false
+anymatch(matchers, 'path/anyjs/foo.js', true, 2, 3); // 2
+anymatch(matchers, 'path/to/bar.js', true, 0, 3); // -1
+
+// using globs to match directories and their children
+anymatch('node_modules', 'node_modules'); // true
+anymatch('node_modules', 'node_modules/somelib/index.js'); // false
+anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
+anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
+anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true
+```
+
+#### anymatch (matchers)
+You can also pass in only your matcher(s) to get a curried function that has
+already been bound to the provided matching criteria. This can be used as an
+`Array.prototype.filter` callback.
+
+```js
+var matcher = anymatch(matchers);
+
+matcher('path/to/file.js'); // true
+matcher('path/anyjs/baz.js', true); // 1
+matcher('path/anyjs/baz.js', true, 2); // -1
+
+['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
+```
+
+Change Log
+----------
+[See release notes page on GitHub](https://github.com/micromatch/anymatch/releases)
+
+NOTE: As of v2.0.0, [micromatch](https://github.com/jonschlinkert/micromatch) moves away from minimatch-parity and inline with Bash. This includes handling backslashes differently (see https://github.com/micromatch/micromatch#backslashes for more information).
+
+NOTE: As of v1.2.0, anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
+for glob pattern matching. Issues with glob pattern matching should be
+reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).

+> Normalize file path slashes to be unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes unless disabled.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save normalize-path
+```
+
+## Usage
+
+```js
+var normalize = require('normalize-path');
+
+normalize('\\foo\\bar\\baz\\');
+//=> '/foo/bar/baz'
+
+normalize('./foo/bar/baz/');
+//=> './foo/bar/baz'
+```
+
+Pass `false` as the last argument to **keep** trailing slashes:
+
+```js
+normalize('./foo/bar/baz/', false);
+//=> './foo/bar/baz/'
+
+normalize('foo\\bar\\baz\\', false);
+//=> 'foo/bar/baz/'
+```

+> Recursively flatten an array or arrays.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save arr-flatten
+```
+
+## Install
+
+Install with [bower](https://bower.io/)
+
+```sh
+$ bower install arr-flatten --save
+```
+
+## Usage
+
+```js
+var flatten = require('arr-flatten');
+
+flatten(['a', ['b', ['c']], 'd', ['e']]);
+//=> ['a', 'b', 'c', 'd', 'e']
+```
+
+## Why another flatten utility?
+
+I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.

+
+> Combines a list of arrays, returning a single array with unique values, using strict equality for comparisons.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i arr-union --save
+```
+
+## Benchmarks
+
+This library is **10-20 times faster** and more performant than [array-union](https://github.com/sindresorhus/array-union).
+
+See the [benchmarks](./benchmark).
+
+```sh
+#1: five-arrays
+  array-union x 511,121 ops/sec ±0.80% (96 runs sampled)
+  arr-union x 5,716,039 ops/sec ±0.86% (93 runs sampled)
+
+#2: ten-arrays
+  array-union x 245,196 ops/sec ±0.69% (94 runs sampled)
+  arr-union x 1,850,786 ops/sec ±0.84% (97 runs sampled)
+
+#3: two-arrays
+  array-union x 563,869 ops/sec ±0.97% (94 runs sampled)
+  arr-union x 9,602,852 ops/sec ±0.87% (92 runs sampled)
+```
+
+## Usage
+
+```js
+var union = require('arr-union');
+
+union(['a'], ['b', 'c'], ['d', 'e', 'f']);
+//=> ['a', 'b', 'c', 'd', 'e', 'f']
+```
+
+Returns only unique elements:
+
+```js
+union(['a', 'a'], ['b', 'c']);
+//=> ['a', 'b', 'c']
+```

+
+```sh
+$ npm install --save array-unique
+```
+
+## Usage
+
+```js
+var unique = require('array-unique');
+
+var arr = ['a', 'b', 'c', 'c'];
+console.log(unique(arr)) //=> ['a', 'b', 'c']
+console.log(arr)         //=> ['a', 'b', 'c']
+
+/* The above modifies the input array. To prevent that at a slight performance cost: */
+var unique = require("array-unique").immutable;
+
+var arr = ['a', 'b', 'c', 'c'];
+console.log(unique(arr)) //=> ['a', 'b', 'c']
+console.log(arr)         //=> ['a', 'b', 'c', 'c']

+# async-each
+
+No-bullshit, ultra-simple, 40-lines-of-code async parallel forEach function for JavaScript.
+
+We don't need junky 30K async libs. Really.
+
+For browsers and node.js.
+
+## Usage
+
+`npm install async-each` if you're using NPM.
+
+For browsers, just include async-each before your scripts and use global variable `asyncEach`
+
+* `each(array, iterator, callback)` — `Array`, `Function`, `(optional) Function`
+* `iterator(item, next)` receives current item and a callback that will mark the item as done. `next` callback receives optional `error, transformedItem` arguments.
+* `callback(error, transformedArray)` optionally receives first error and transformed result `Array`.
+
+```javascript
+var each = require('async-each');
+each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
+  if (error) console.error(error);
+  console.log('Contents for a, b and c:', contents);
+});
+
+asyncEach(list, fn, callback); // use global var in browser
+```

+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
+BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+
+1. Definitions
+
+ a. "Adaptation" means a work based upon the Work, or upon the Work and
+    other pre-existing works, such as a translation, adaptation,
+    derivative work, arrangement of music or other alterations of a
+    literary or artistic work, or phonogram or performance and includes
+    cinematographic adaptations or any other form in which the Work may be
+    recast, transformed, or adapted including in any form recognizably
+    derived from the original, except that a work that constitutes a
+    Collection will not be considered an Adaptation for the purpose of
+    this License. For the avoidance of doubt, where the Work is a musical
+    work, performance or phonogram, the synchronization of the Work in
+    timed-relation with a moving image ("synching") will be considered an
+    Adaptation for the purpose of this License.
+ b. "Collection" means a collection of literary or artistic works, such as
+    encyclopedias and anthologies, or performances, phonograms or
+    broadcasts, or other works or subject matter other than works listed
+    in Section 1(f) below, which, by reason of the selection and
+    arrangement of their contents, constitute intellectual creations, in
+    which the Work is included in its entirety in unmodified form along
+    with one or more other contributions, each constituting separate and
+    independent works in themselves, which together are assembled into a
+    collective whole. A work that constitutes a Collection will not be
+    considered an Adaptation (as defined above) for the purposes of this
+    License.
+ c. "Distribute" means to make available to the public the original and
+    copies of the Work or Adaptation, as appropriate, through sale or
+    other transfer of ownership.
+ d. "Licensor" means the individual, individuals, entity or entities that
+    offer(s) the Work under the terms of this License.
+ e. "Original Author" means, in the case of a literary or artistic work,
+    the individual, individuals, entity or entities who created the Work
+    or if no individual or entity can be identified, the publisher; and in
+    addition (i) in the case of a performance the actors, singers,
+    musicians, dancers, and other persons who act, sing, deliver, declaim,
+    play in, interpret or otherwise perform literary or artistic works or
+    expressions of folklore; (ii) in the case of a phonogram the producer
+    being the person or legal entity who first fixes the sounds of a
+    performance or other sounds; and, (iii) in the case of broadcasts, the
+    organization that transmits the broadcast.
+ f. "Work" means the literary and/or artistic work offered under the terms
+    of this License including without limitation any production in the
+    literary, scientific and artistic domain, whatever may be the mode or
+    form of its expression including digital form, such as a book,
+    pamphlet and other writing; a lecture, address, sermon or other work
+    of the same nature; a dramatic or dramatico-musical work; a
+    choreographic work or entertainment in dumb show; a musical
+    composition with or without words; a cinematographic work to which are
+    assimilated works expressed by a process analogous to cinematography;
+    a work of drawing, painting, architecture, sculpture, engraving or
+    lithography; a photographic work to which are assimilated works
+    expressed by a process analogous to photography; a work of applied
+    art; an illustration, map, plan, sketch or three-dimensional work
+    relative to geography, topography, architecture or science; a
+    performance; a broadcast; a phonogram; a compilation of data to the
+    extent it is protected as a copyrightable work; or a work performed by
+    a variety or circus performer to the extent it is not otherwise
+    considered a literary or artistic work.
+ g. "You" means an individual or entity exercising rights under this
+    License who has not previously violated the terms of this License with
+    respect to the Work, or who has received express permission from the
+    Licensor to exercise rights under this License despite a previous
+    violation.
+ h. "Publicly Perform" means to perform public recitations of the Work and
+    to communicate to the public those public recitations, by any means or
+    process, including by wire or wireless means or public digital
+    performances; to make available to the public Works in such a way that
+    members of the public may access these Works from a place and at a
+    place individually chosen by them; to perform the Work to the public
+    by any means or process and the communication to the public of the
+    performances of the Work, including by public digital performance; to
+    broadcast and rebroadcast the Work by any means including signs,
+    sounds or images.
+ i. "Reproduce" means to make copies of the Work by any means including
+    without limitation by sound or visual recordings and the right of
+    fixation and reproducing fixations of the Work, including storage of a
+    protected performance or phonogram in digital form or other electronic
+    medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+limit, or restrict any uses free from copyright or rights arising from
+limitations or exceptions that are provided for in connection with the
+copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+    Collections, and to Reproduce the Work as incorporated in the
+    Collections;
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+    including any translation in any medium, takes reasonable steps to
+    clearly label, demarcate or otherwise identify that changes were made
+    to the original Work. For example, a translation could be marked "The
+    original work was translated from English to Spanish," or a
+    modification could indicate "The original work has been modified.";
+ c. to Distribute and Publicly Perform the Work including as incorporated
+    in Collections; and,
+ d. to Distribute and Publicly Perform Adaptations.
+ e. For the avoidance of doubt:
+
+     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme cannot be waived, the Licensor
+        reserves the exclusive right to collect such royalties for any
+        exercise by You of the rights granted under this License;
+    ii. Waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme can be waived, the Licensor waives the
+        exclusive right to collect such royalties for any exercise by You
+        of the rights granted under this License; and,
+   iii. Voluntary License Schemes. The Licensor waives the right to
+        collect royalties, whether individually or, in the event that the
+        Licensor is a member of a collecting society that administers
+        voluntary licensing schemes, via that society, from any exercise
+        by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights in
+other media and formats. Subject to Section 8(f), all rights not expressly
+granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms
+    of this License. You must include a copy of, or the Uniform Resource
+    Identifier (URI) for, this License with every copy of the Work You
+    Distribute or Publicly Perform. You may not offer or impose any terms
+    on the Work that restrict the terms of this License or the ability of
+    the recipient of the Work to exercise the rights granted to that
+    recipient under the terms of the License. You may not sublicense the
+    Work. You must keep intact all notices that refer to this License and
+    to the disclaimer of warranties with every copy of the Work You
+    Distribute or Publicly Perform. When You Distribute or Publicly
+    Perform the Work, You may not impose any effective technological
+    measures on the Work that restrict the ability of a recipient of the
+    Work from You to exercise the rights granted to that recipient under
+    the terms of the License. This Section 4(a) applies to the Work as
+    incorporated in a Collection, but this does not require the Collection
+    apart from the Work itself to be made subject to the terms of this
+    License. If You create a Collection, upon notice from any Licensor You
+    must, to the extent practicable, remove from the Collection any credit
+    as required by Section 4(b), as requested. If You create an
+    Adaptation, upon notice from any Licensor You must, to the extent
+    practicable, remove from the Adaptation any credit as required by
+    Section 4(b), as requested.
+ b. If You Distribute, or Publicly Perform the Work or any Adaptations or
+    Collections, You must, unless a request has been made pursuant to
+    Section 4(a), keep intact all copyright notices for the Work and
+    provide, reasonable to the medium or means You are utilizing: (i) the
+    name of the Original Author (or pseudonym, if applicable) if supplied,
+    and/or if the Original Author and/or Licensor designate another party
+    or parties (e.g., a sponsor institute, publishing entity, journal) for
+    attribution ("Attribution Parties") in Licensor's copyright notice,
+    terms of service or by other reasonable means, the name of such party
+    or parties; (ii) the title of the Work if supplied; (iii) to the
+    extent reasonably practicable, the URI, if any, that Licensor
+    specifies to be associated with the Work, unless such URI does not
+    refer to the copyright notice or licensing information for the Work;
+    and (iv) , consistent with Section 3(b), in the case of an Adaptation,
+    a credit identifying the use of the Work in the Adaptation (e.g.,
+    "French translation of the Work by Original Author," or "Screenplay
+    based on original Work by Original Author"). The credit required by
+    this Section 4 (b) may be implemented in any reasonable manner;
+    provided, however, that in the case of a Adaptation or Collection, at
+    a minimum such credit will appear, if a credit for all contributing
+    authors of the Adaptation or Collection appears, then as part of these
+    credits and in a manner at least as prominent as the credits for the
+    other contributing authors. For the avoidance of doubt, You may only
+    use the credit required by this Section for the purpose of attribution
+    in the manner set out above and, by exercising Your rights under this
+    License, You may not implicitly or explicitly assert or imply any
+    connection with, sponsorship or endorsement by the Original Author,
+    Licensor and/or Attribution Parties, as appropriate, of You or Your
+    use of the Work, without the separate, express prior written
+    permission of the Original Author, Licensor and/or Attribution
+    Parties.
+ c. Except as otherwise agreed in writing by the Licensor or as may be
+    otherwise permitted by applicable law, if You Reproduce, Distribute or
+    Publicly Perform the Work either by itself or as part of any
+    Adaptations or Collections, You must not distort, mutilate, modify or
+    take other derogatory action in relation to the Work which would be
+    prejudicial to the Original Author's honor or reputation. Licensor
+    agrees that in those jurisdictions (e.g. Japan), in which any exercise
+    of the right granted in Section 3(b) of this License (the right to
+    make Adaptations) would be deemed to be a distortion, mutilation,
+    modification or other derogatory action prejudicial to the Original
+    Author's honor and reputation, the Licensor will waive or not assert,
+    as appropriate, this Section, to the fullest extent permitted by the
+    applicable national law, to enable You to reasonably exercise Your
+    right under Section 3(b) of this License (right to make Adaptations)
+    but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
+OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
+ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
+ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate
+    automatically upon any breach by You of the terms of this License.
+    Individuals or entities who have received Adaptations or Collections
+    from You under this License, however, will not have their licenses
+    terminated provided such individuals or entities remain in full
+    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+    survive any termination of this License.
+ b. Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the
+    Work under different license terms or to stop distributing the Work at
+    any time; provided, however that any such election will not serve to
+    withdraw this License (or any other license that has been, or is
+    required to be, granted under the terms of this License), and this
+    License will continue in full force and effect unless terminated as
+    stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection,
+    the Licensor offers to the recipient a license to the Work on the same
+    terms and conditions as the license granted to You under this License.
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+    offers to the recipient a license to the original Work on the same
+    terms and conditions as the license granted to You under this License.
+ c. If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this License, and without further action
+    by the parties to this agreement, such provision shall be reformed to
+    the minimum extent necessary to make such provision valid and
+    enforceable.
+ d. No term or provision of this License shall be deemed waived and no
+    breach consented to unless such waiver or consent shall be in writing
+    and signed by the party to be charged with such waiver or consent.
+ e. This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings,
+    agreements or representations with respect to the Work not specified
+    here. Licensor shall not be bound by any additional provisions that
+    may appear in any communication from You. This License may not be
+    modified without the mutual written agreement of the Licensor and You.
+ f. The rights granted under, and the subject matter referenced, in this
+    License were drafted utilizing the terminology of the Berne Convention
+    for the Protection of Literary and Artistic Works (as amended on
+    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
+    and the Universal Copyright Convention (as revised on July 24, 1971).
+    These rights and subject matter take effect in the relevant
+    jurisdiction in which the License terms are sought to be enforced
+    according to the corresponding provisions of the implementation of
+    those treaty provisions in the applicable national law. If the
+    standard suite of rights granted under applicable copyright law
+    includes additional rights not granted under this License, such
+    additional rights are deemed to be included in the License; this
+    License is not intended to restrict the license of any rights under
+    applicable law.

+Uses `Buffer` to emulate the exact functionality of the browser's atob.
+
+Note: Unicode may be handled incorrectly (like the browser).
+
+It turns base64-encoded <strong>a</strong>scii data back **to** <strong>b</strong>inary.

+
+> base is the foundation for creating modular, unit testable and highly pluggable node.js applications, starting with a handful of common methods, like `set`, `get`, `del` and `use`.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base
+```
+
+## What is Base?
+
+Base is a framework for rapidly creating high quality node.js applications, using plugins like building blocks.
+
+### Guiding principles
+
+The core team follows these principles to help guide API decisions:
+
+* **Compact API surface**: The smaller the API surface, the easier the library will be to learn and use.
+* **Easy to extend**: Implementors can use any npm package, and write plugins in pure JavaScript. If you're building complex apps, Base simplifies inheritance.
+* **Easy to test**: No special setup should be required to unit test `Base` or base plugins
+
+### Minimal API surface
+
+[The API](#api) was designed to provide only the minimum necessary functionality for creating a useful application, with or without [plugins](#plugins).
+
+**Base core**
+
+Base itself ships with only a handful of [useful methods](#api), such as:
+
+* `.set`: for setting values on the instance
+* `.get`: for getting values from the instance
+* `.has`: to check if a property exists on the instance
+* `.define`: for setting non-enumerable values on the instance
+* `.use`: for adding plugins
+
+**Be generic**
+
+When deciding on method to add or remove, we try to answer these questions:
+
+1. Will all or most Base applications need this method?
+2. Will this method encourage practices or enforce conventions that are beneficial to implementors?
+3. Can or should this be done in a plugin instead?
+
+### Composability
+
+**Plugin system**
+
+It couldn't be easier to extend Base with any features or custom functionality you can think of.
+
+Base plugins are just functions that take an instance of `Base`:
+
+```js
+var base = new Base();
+
+function plugin(base) {
+  // do plugin stuff, in pure JavaScript
+}
+// use the plugin
+base.use(plugin);
+```
+
+**Inheritance**
+
+Easily inherit Base using `.extend`:
+
+```js
+var Base = require('base');
+
+function MyApp() {
+  Base.call(this);
+}
+Base.extend(MyApp);
+
+var app = new MyApp();
+app.set('a', 'b');
+app.get('a');
+//=> 'b';
+```
+
+**Inherit or instantiate with a namespace**
+
+By default, the `.get`, `.set` and `.has` methods set and get values from the root of the `base` instance. You can customize this using the `.namespace` method exposed on the exported function. For example:
+
+```js
+var Base = require('base');
+// get and set values on the `base.cache` object
+var base = Base.namespace('cache');
+
+var app = base();
+app.set('foo', 'bar');
+console.log(app.cache.foo);
+//=> 'bar'
+```
+
+## API
+
+**Usage**
+
+```js
+var Base = require('base');
+var app = new Base();
+app.set('foo', 'bar');
+console.log(app.foo);
+//=> 'bar'
+```
+
+### [Base](index.js#L44)
+
+Create an instance of `Base` with the given `config` and `options`.
+
+**Params**
+
+* `config` **{Object}**: If supplied, this object is passed to [cache-base](https://github.com/jonschlinkert/cache-base) to merge onto the the instance upon instantiation.
+* `options` **{Object}**: If supplied, this object is used to initialize the `base.options` object.
+
+**Example**
+
+```js
+// initialize with `config` and `options`
+var app = new Base({isApp: true}, {abc: true});
+app.set('foo', 'bar');
+
+// values defined with the given `config` object will be on the root of the instance
+console.log(app.baz); //=> undefined
+console.log(app.foo); //=> 'bar'
+// or use `.get`
+console.log(app.get('isApp')); //=> true
+console.log(app.get('foo')); //=> 'bar'
+
+// values defined with the given `options` object will be on `app.options
+console.log(app.options.abc); //=> true
+```
+
+### [.is](index.js#L107)
+
+Set the given `name` on `app._name` and `app.is*` properties. Used for doing lookups in plugins.
+
+**Params**
+
+* `name` **{String}**
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+app.is('foo');
+console.log(app._name);
+//=> 'foo'
+console.log(app.isFoo);
+//=> true
+app.is('bar');
+console.log(app.isFoo);
+//=> true
+console.log(app.isBar);
+//=> true
+console.log(app._name);
+//=> 'bar'
+```
+
+### [.isRegistered](index.js#L145)
+
+Returns true if a plugin has already been registered on an instance.
+
+Plugin implementors are encouraged to use this first thing in a plugin
+to prevent the plugin from being called more than once on the same
+instance.
+
+**Params**
+
+* `name` **{String}**: The plugin name.
+* `register` **{Boolean}**: If the plugin if not already registered, to record it as being registered pass `true` as the second argument.
+* `returns` **{Boolean}**: Returns true if a plugin is already registered.
+
+**Events**
+
+* `emits`: `plugin` Emits the name of the plugin being registered. Useful for unit tests, to ensure plugins are only registered once.
+
+**Example**
+
+```js
+var base = new Base();
+base.use(function(app) {
+  if (app.isRegistered('myPlugin')) return;
+  // do stuff to `app`
+});
+
+// to also record the plugin as being registered
+base.use(function(app) {
+  if (app.isRegistered('myPlugin', true)) return;
+  // do stuff to `app`
+});
+```
+
+### [.use](index.js#L175)
+
+Define a plugin function to be called immediately upon init. Plugins are chainable and expose the following arguments to the plugin function:
+
+* `app`: the current instance of `Base`
+* `base`: the [first ancestor instance](#base) of `Base`
+
+**Params**
+
+* `fn` **{Function}**: plugin function to call
+* `returns` **{Object}**: Returns the item instance for chaining.
+
+**Example**
+
+```js
+var app = new Base()
+  .use(foo)
+  .use(bar)
+  .use(baz)
+```
+
+### [.define](index.js#L197)
+
+The `.define` method is used for adding non-enumerable property on the instance. Dot-notation is **not supported** with `define`.
+
+**Params**
+
+* `key` **{String}**: The name of the property to define.
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+// arbitrary `render` function using lodash `template`
+app.define('render', function(str, locals) {
+  return _.template(str)(locals);
+});
+```
+
+### [.mixin](index.js#L222)
+
+Mix property `key` onto the Base prototype. If base is inherited using `Base.extend` this method will be overridden by a new `mixin` method that will only add properties to the prototype of the inheriting application.
+
+**Params**
+
+* `key` **{String}**
+* `val` **{Object|Array}**
+* `returns` **{Object}**: Returns the `base` instance for chaining.
+
+**Example**
+
+```js
+app.mixin('foo', function() {
+  // do stuff
+});
+```
+
+### [.base](index.js#L268)
+
+Getter/setter used when creating nested instances of `Base`, for storing a reference to the first ancestor instance. This works by setting an instance of `Base` on the `parent` property of a "child" instance. The `base` property defaults to the current instance if no `parent` property is defined.
+
+**Example**
+
+```js
+// create an instance of `Base`, this is our first ("base") instance
+var first = new Base();
+first.foo = 'bar'; // arbitrary property, to make it easier to see what's happening later
+
+// create another instance
+var second = new Base();
+// create a reference to the first instance (`first`)
+second.parent = first;
+
+// create another instance
+var third = new Base();
+// create a reference to the previous instance (`second`)
+// repeat this pattern every time a "child" instance is created
+third.parent = second;
+
+// we can always access the first instance using the `base` property
+console.log(first.base.foo);
+//=> 'bar'
+console.log(second.base.foo);
+//=> 'bar'
+console.log(third.base.foo);
+//=> 'bar'
+// and now you know how to get to third base ;)
+```
+
+### [#use](index.js#L293)
+
+Static method for adding global plugin functions that will be added to an instance when created.
+
+**Params**
+
+* `fn` **{Function}**: Plugin function to use on each instance.
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.use(function(app) {
+  app.foo = 'bar';
+});
+var app = new Base();
+console.log(app.foo);
+//=> 'bar'
+```
+
+### [#extend](index.js#L337)
+
+Static method for inheriting the prototype and static methods of the `Base` class. This method greatly simplifies the process of creating inheritance-based applications. See [static-extend](https://github.com/jonschlinkert/static-extend) for more details.
+
+**Params**
+
+* `Ctor` **{Function}**: constructor to extend
+* `methods` **{Object}**: Optional prototype properties to mix in.
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+var extend = cu.extend(Parent);
+Parent.extend(Child);
+
+// optional methods
+Parent.extend(Child, {
+  foo: function() {},
+  bar: function() {}
+});
+```
+
+### [#mixin](index.js#L379)
+
+Used for adding methods to the `Base` prototype, and/or to the prototype of child instances. When a mixin function returns a function, the returned function is pushed onto the `.mixins` array, making it available to be used on inheriting classes whenever `Base.mixins()` is called (e.g. `Base.mixins(Child)`).
+
+**Params**
+
+* `fn` **{Function}**: Function to call
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.mixin(function(proto) {
+  proto.foo = function(msg) {
+    return 'foo ' + msg;
+  };
+});
+```
+
+### [#mixins](index.js#L401)
+
+Static method for running global mixin functions against a child constructor. Mixins must be registered before calling this method.
+
+**Params**
+
+* `Child` **{Function}**: Constructor function of a child class
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.extend(Child);
+Base.mixins(Child);
+```
+
+### [#inherit](index.js#L420)
+
+Similar to `util.inherit`, but copies all static properties, prototype properties, and getters/setters from `Provider` to `Receiver`. See [class-utils](https://github.com/jonschlinkert/class-utils#inherit) for more details.
+
+**Params**
+
+* `Receiver` **{Function}**: Receiving (child) constructor
+* `Provider` **{Function}**: Providing (parent) constructor
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.inherit(Foo, Bar);
+```
+

+
+Generic basic auth Authorization header field parser for whatever.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```
+$ npm install basic-auth
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var auth = require('basic-auth')
+```
+
+### auth(req)
+
+Get the basic auth credentials from the given request. The `Authorization`
+header is parsed and if the header is invalid, `undefined` is returned,
+otherwise an object with `name` and `pass` properties.
+
+### auth.parse(string)
+
+Parse a basic auth authorization header string. This will return an object
+with `name` and `pass` properties, or `undefined` if the string is invalid.
+
+## Example
+
+Pass a Node.js request object to the module export. If parsing fails
+`undefined` is returned, otherwise an object with `.name` and `.pass`.
+
+<!-- eslint-disable no-unused-vars, no-undef -->
+
+```js
+var auth = require('basic-auth')
+var user = auth(req)
+// => { name: 'something', pass: 'whatever' }
+```
+
+A header string from any other location can also be parsed with
+`auth.parse`, for example a `Proxy-Authorization` header:
+
+<!-- eslint-disable no-unused-vars, no-undef -->
+
+```js
+var auth = require('basic-auth')
+var user = auth.parse(req.getHeader('Proxy-Authorization'))
+```
+
+### With vanilla node.js http server
+
+```js
+var http = require('http')
+var auth = require('basic-auth')
+var compare = require('tsscmp')
+
+// Create server
+var server = http.createServer(function (req, res) {
+  var credentials = auth(req)
+
+  // Check credentials
+  // The "check" function will typically be against your user store
+  if (!credentials || !check(credentials.name, credentials.pass)) {
+    res.statusCode = 401
+    res.setHeader('WWW-Authenticate', 'Basic realm="example"')
+    res.end('Access denied')
+  } else {
+    res.end('Access granted')
+  }
+})
+
+// Basic function to validate credentials for example
+function check (name, pass) {
+  var valid = true
+
+  // Simple method to prevent short-circut and use timing-safe compare
+  valid = compare(name, 'john') && valid
+  valid = compare(pass, 'secret') && valid
+
+  return valid
+}
+
+// Listen
+server.listen(3000)
+```
