+## Install
+
+```sh
+$ npm install serve-static
+```
+
+## API
+
+```js
+var serveStatic = require('serve-static')
+```
+
+### serveStatic(root, options)
+
+Create a new middleware function to serve files from within a given root
+directory. The file to serve will be determined by combining `req.url`
+with the provided root directory. When a file is not found, instead of
+sending a 404 response, this module will instead call `next()` to move on
+to the next middleware, allowing for stacking and fall-backs.
+
+#### Options
+
+##### dotfiles
+
+ Set how "dotfiles" are treated when encountered. A dotfile is a file
+or directory that begins with a dot ("."). Note this check is done on
+the path itself without checking if the path actually exists on the
+disk. If `root` is specified, only the dotfiles above the root are
+checked (i.e. the root itself can be within a dotfile when set
+to "deny").
+
+The default value is `'ignore'`.
+
+  - `'allow'` No special treatment for dotfiles.
+  - `'deny'` Send a 403 for any request for a dotfile.
+  - `'ignore'` Pretend like the dotfile does not exist and call `next()`.
+
+##### etag
+
+Enable or disable etag generation, defaults to true.
+
+##### extensions
+
+Set file extension fallbacks. When set, if a file is not found, the given
+extensions will be added to the file name and search for. The first that
+exists will be served. Example: `['html', 'htm']`.
+
+The default value is `false`.
+
+##### index
+
+By default this module will send "index.html" files in response to a request
+on a directory. To disable this set `false` or to supply a new index pass a
+string or an array in preferred order.
+
+##### lastModified
+
+Enable or disable `Last-Modified` header, defaults to true. Uses the file
+system's last modified value.
+
+##### maxAge
+
+Provide a max-age in milliseconds for http caching, defaults to 0. This
+can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
+module.
+
+##### redirect
+
+Redirect to trailing "/" when the pathname is a dir. Defaults to `true`.
+
+##### setHeaders
+
+Function to set custom headers on response. Alterations to the headers need to
+occur synchronously. The function is called as `fn(res, path, stat)`, where
+the arguments are:
+
+  - `res` the response object
+  - `path` the file path that is being sent
+  - `stat` the stat object of the file that is being sent
+
+## Examples
+
+### Serve files with vanilla node.js http server
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+// Serve up public/ftp folder
+var serve = serveStatic('public/ftp', {'index': ['index.html', 'index.htm']})
+
+// Create server
+var server = http.createServer(function(req, res){
+  var done = finalhandler(req, res)
+  serve(req, res, done)
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serve all files as downloads
+
+```js
+var contentDisposition = require('content-disposition')
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+// Serve up public/ftp folder
+var serve = serveStatic('public/ftp', {
+  'index': false,
+  'setHeaders': setHeaders
+})
+
+// Set header to force download
+function setHeaders(res, path) {
+  res.setHeader('Content-Disposition', contentDisposition(path))
+}
+
+// Create server
+var server = http.createServer(function(req, res){
+  var done = finalhandler(req, res)
+  serve(req, res, done)
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serving using express
+
+```js
+var express = require('express')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic('public/ftp', {'index': ['default.html', 'default.htm']}))
+app.listen(3000)
+```

+# parseurl
+
+[![NPM version](https://badge.fury.io/js/parseurl.svg)](http://badge.fury.io/js/parseurl)
+[![Build Status](https://travis-ci.org/expressjs/parseurl.svg?branch=master)](https://travis-ci.org/expressjs/parseurl)
+[![Coverage Status](https://img.shields.io/coveralls/expressjs/parseurl.svg?branch=master)](https://coveralls.io/r/expressjs/parseurl)
+
+Parse a URL with memoization.
+
+## Install
+
+```bash
+$ npm install parseurl
+```
+
+## API
+
+```js
+var parseurl = require('parseurl')
+```
+
+### parseurl(req)
+
+Parse the URL of the given request object (looks at the `req.url` property)
+and return the result. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.url` does
+not change will return a cached parsed object, rather than parsing again.
+
+### parseurl.original(req)
+
+Parse the original URL of the given request object and return the result.
+This works by trying to parse `req.originalUrl` if it is a string, otherwise
+parses `req.url`. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.originalUrl`
+does not change will return a cached parsed object, rather than parsing again.

+
+Send is a library for streaming files from the file system as a http response
+supporting partial responses (Ranges), conditional-GET negotiation, high test
+coverage, and granular events which may be leveraged to take appropriate actions
+in your application or framework.
+
+Looking to serve up entire folders mapped to URLs? Try [serve-static](https://www.npmjs.org/package/serve-static).
+
+## Installation
+
+```bash
+$ npm install send
+```
+
+## API
+
+```js
+var send = require('send')
+```
+
+### send(req, path, [options])
+
+Create a new `SendStream` for the given path to send to a `res`. The `req` is
+the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded,
+not the actual file-system path).
+
+#### Options
+
+##### dotfiles
+
+Set how "dotfiles" are treated when encountered. A dotfile is a file
+or directory that begins with a dot ("."). Note this check is done on
+the path itself without checking if the path actually exists on the
+disk. If `root` is specified, only the dotfiles above the root are
+checked (i.e. the root itself can be within a dotfile when when set
+to "deny").
+
+  - `'allow'` No special treatment for dotfiles.
+  - `'deny'` Send a 403 for any request for a dotfile.
+  - `'ignore'` Pretend like the dotfile does not exist and 404.
+
+The default value is _similar_ to `'ignore'`, with the exception that
+this default will not ignore the files within a directory that begins
+with a dot, for backward-compatibility.
+
+##### etag
+
+Enable or disable etag generation, defaults to true.
+
+##### extensions
+
+If a given file doesn't exist, try appending one of the given extensions,
+in the given order. By default, this is disabled (set to `false`). An
+example value that will serve extension-less HTML files: `['html', 'htm']`.
+This is skipped if the requested file already has an extension.
+
+##### index
+
+By default send supports "index.html" files, to disable this
+set `false` or to supply a new index pass a string or an array
+in preferred order.
+
+##### lastModified
+
+Enable or disable `Last-Modified` header, defaults to true. Uses the file
+system's last modified value.
+
+##### maxAge
+
+Provide a max-age in milliseconds for http caching, defaults to 0.
+This can also be a string accepted by the
+[ms](https://www.npmjs.org/package/ms#readme) module.
+
+##### root
+
+Serve files relative to `path`.
+
+### Events
+
+The `SendStream` is an event emitter and will emit the following events:
+
+  - `error` an error occurred `(err)`
+  - `directory` a directory was requested
+  - `file` a file was requested `(path, stat)`
+  - `headers` the headers are about to be set on a file `(res, path, stat)`
+  - `stream` file streaming has started `(stream)`
+  - `end` streaming has completed
+
+### .pipe
+
+The `pipe` method is used to pipe the response into the Node.js HTTP response
+object, typically `send(req, path, options).pipe(res)`.
+
+## Error-handling
+
+By default when no `error` listeners are present an automatic response will be
+made, otherwise you have full control over the response, aka you may show a 5xx
+page etc.
+
+## Caching
+
+It does _not_ perform internal caching, you should use a reverse proxy cache
+such as Varnish for this, or those fancy things called CDNs. If your
+application is small enough that it would benefit from single-node memory
+caching, it's small enough that it does not need caching at all ;).
+
+## Debugging
+
+To enable `debug()` instrumentation output export __DEBUG__:
+
+```
+$ DEBUG=send node app
+```
+
+## Running tests
+
+```
+$ npm install
+$ npm test
+```
+
+## Examples
+
+### Small example
+
+```js
+var http = require('http');
+var send = require('send');
+
+var app = http.createServer(function(req, res){
+  send(req, req.url).pipe(res);
+}).listen(3000);
+```
+
+Serving from a root directory with custom error-handling:
+
+```js
+var http = require('http');
+var send = require('send');
+var url = require('url');
+
+var app = http.createServer(function(req, res){
+  // your custom error-handling logic:
+  function error(err) {
+    res.statusCode = err.status || 500;
+    res.end(err.message);
+  }
+
+  // your custom headers
+  function headers(res, path, stat) {
+    // serve all files for download
+    res.setHeader('Content-Disposition', 'attachment');
+  }
+
+  // your custom directory handling logic:
+  function redirect() {
+    res.statusCode = 301;
+    res.setHeader('Location', req.url + '/');
+    res.end('Redirecting to ' + req.url + '/');
+  }
+
+  // transfer arbitrary files from within
+  // /www/example.com/public/*
+  send(req, url.parse(req.url).pathname, {root: '/www/example.com/public'})
+  .on('error', error)
+  .on('directory', redirect)
+  .on('headers', headers)
+  .pipe(res);
+}).listen(3000);
+```

+Deprecate all the things
+
+> With great modules comes great responsibility; mark things deprecated!
+
+## Install
+
+```sh
+$ npm install depd
+```
+
+## API
+
+```js
+var deprecate = require('depd')('my-module')
+```
+
+This library allows you to display deprecation messages to your users.
+This library goes above and beyond with deprecation warnings by
+introspection of the call stack (but only the bits that it is interested
+in).
+
+Instead of just warning on the first invocation of a deprecated
+function and never again, this module will warn on the first invocation
+of a deprecated function per unique call site, making it ideal to alert
+users of all deprecated uses across the code base, rather than just
+whatever happens to execute first.
+
+The deprecation warnings from this module also include the file and line
+information for the call into the module that the deprecated function was
+in.
+
+**NOTE** this library has a similar interface to the `debug` module, and
+this module uses the calling file to get the boundary for the call stacks,
+so you should always create a new `deprecate` object in each file and not
+within some central file.
+
+### depd(namespace)
+
+Create a new deprecate function that uses the given namespace name in the
+messages and will display the call site prior to the stack entering the
+file this function was called from. It is highly suggested you use the
+name of your module as the namespace.
+
+### deprecate(message)
+
+Call this function from deprecated code to display a deprecation message.
+This message will appear once per unique caller site. Caller site is the
+first call site in the stack in a different file from the caller of this
+function.
+
+If the message is omitted, a message is generated for you based on the site
+of the `deprecate()` call and will display the name of the function called,
+similar to the name displayed in a stack trace.
+
+### deprecate.function(fn, message)
+
+Call this function to wrap a given function in a deprecation message on any
+call to the function. An optional message can be supplied to provide a custom
+message.
+
+### deprecate.property(obj, prop, message)
+
+Call this function to wrap a given property on object in a deprecation message
+on any accessing or setting of the property. An optional message can be supplied
+to provide a custom message.
+
+The method must be called on the object where the property belongs (not
+inherited from the prototype).
+
+If the property is a data descriptor, it will be converted to an accessor
+descriptor in order to display the deprecation message.
+
+### process.on('deprecation', fn)
+
+This module will allow easy capturing of deprecation errors by emitting the
+errors as the type "deprecation" on the global `process`. If there are no
+listeners for this type, the errors are written to STDERR as normal, but if
+there are any listeners, nothing will be written to STDERR and instead only
+emitted. From there, you can write the errors in a different format or to a
+logging source.
+
+The error represents the deprecation and is emitted only once with the same
+rules as writing to STDERR. The error has the following properties:
+
+  - `message` - This is the message given by the library
+  - `name` - This is always `'DeprecationError'`
+  - `namespace` - This is the namespace the deprecation came from
+  - `stack` - This is the stack of the call to the deprecated thing
+
+Example `error.stack` output:
+
+```
+DeprecationError: my-cool-module deprecated oldfunction
+    at Object.<anonymous> ([eval]-wrapper:6:22)
+    at Module._compile (module.js:456:26)
+    at evalScript (node.js:532:25)
+    at startup (node.js:80:7)
+    at node.js:902:3
+```
+
+### process.env.NO_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
+is provided as a quick solution to silencing deprecation warnings from being
+output. The format of this is similar to that of `DEBUG`:
+
+```sh
+$ NO_DEPRECATION=my-module,othermod node app.js
+```
+
+This will suppress deprecations from being output for "my-module" and "othermod".
+The value is a list of comma-separated namespaces. To suppress every warning
+across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--no-deprecation` to the `node` executable will suppress
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not suppress the deperecations given to any "deprecation"
+event listeners, just the output to STDERR.
+
+### process.env.TRACE_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
+is provided as a solution to getting more detailed location information in deprecation
+warnings by including the entire stack trace. The format of this is the same as
+`NO_DEPRECATION`:
+
+```sh
+$ TRACE_DEPRECATION=my-module,othermod node app.js
+```
+
+This will include stack traces for deprecations being output for "my-module" and
+"othermod". The value is a list of comma-separated namespaces. To trace every
+warning across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--trace-deprecation` to the `node` executable will trace
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
+
+## Display
+
+![message](files/message.png)
+
+When a user calls a function in your library that you mark deprecated, they
+will see the following written to STDERR (in the given colors, similar colors
+and layout to the `debug` module):
+
+```
+bright cyan    bright yellow
+|              |          reset       cyan
+|              |          |           |

+|              |          |           |
+namespace      |          |           location of mycoolmod.oldfunction() call
+               |          deprecation message
+               the word "deprecated"
+```
+
+If the user redirects their STDERR to a file or somewhere that does not support
+colors, they see (similar layout to the `debug` module):
+
+```
+Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22
+▲                             ▲              ▲          ▲              ▲
+|                             |              |          |              |
+timestamp of message          namespace      |          |             location of mycoolmod.oldfunction() call
+                                             |          deprecation message
+                                             the word "deprecated"
+```
+
+## Examples
+
+### Deprecating all calls to a function
+
+This will display a deprecated message about "oldfunction" being deprecated
+from "my-module" on STDERR.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+// message automatically derived from function name
+// Object.oldfunction
+exports.oldfunction = deprecate.function(function oldfunction() {
+  // all calls to function are deprecated
+})
+
+// specific message
+exports.oldfunction = deprecate.function(function () {
+  // all calls to function are deprecated
+}, 'oldfunction')
+```
+
+### Conditionally deprecating a function call
+
+This will display a deprecated message about "weirdfunction" being deprecated
+from "my-module" on STDERR when called with less than 2 arguments.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  }
+}
+```
+
+When calling `deprecate` as a function, the warning is counted per call site
+within your own module, so you can display different deprecations depending
+on different situations and the users will still get all the warnings:
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  } else if (typeof arguments[0] !== 'string') {
+    // calls with non-string first argument are deprecated
+    deprecate('weirdfunction non-string first arg')
+  }
+}
+```
+
+### Deprecating property access
+
+This will display a deprecated message about "oldprop" being deprecated
+from "my-module" on STDERR when accessed. A deprecation will be displayed
+when setting the value and when getting the value.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.oldprop = 'something'
+
+// message automatically derives from property name
+deprecate.property(exports, 'oldprop')
+
+// explicit message
+deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
+```

+
+Create simple ETags
+
+## Installation
+
+```sh
+$ npm install etag
+```
+
+## API
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if a "strong" or a "weak" ETag will be generated. The ETag can only
+really be a strong as the given input.
+
+## Testing
+
+```sh
+$ npm test
+```
+
+## Benchmark
+
+```bash

+
+Module for calculating Cyclic Redundancy Check (CRC).
+
+## Features
+
+* Full test suite comparing values against reference `pycrc` implementation.
+* Version 3.x is 3x to 4x faster than version 2.x.
+* Pure JavaScript implementation, no dependencies.
+* Provides CRC Tables for optimized calculations.
+* Provides support for the following CRC algorithms:
+  * CRC1 `crc.crc1(…)`
+  * CRC8 `crc.crc8(…)`
+  * CRC8 1-Wire `crc.crc81wire(…)`
+  * CRC16 `crc.crc16(…)`
+  * CRC16 CCITT `crc.crc16ccitt(…)`
+  * CRC16 Modbus `crc.crc16modbus(…)`
+  * CRC24 `crc.crc24(…)`
+  * CRC32 `crc.crc32(…)`
+
+## IMPORTANT
+
+If you've used `crc` module prior to version 2.x, you might have some inconsistentcies with the current implementation because it relied on very old code and wasn't checked against reference implementation. If you upgrading from 1.x, please take special care.
+
+## Support
+
+<a href="https://blockchain.info/address/1CZyBREeHTmy8C5zVGHZHPwqBuWFmEuUCQ"><img src="bitcoin.png" width="150" align="right"/></a> Please support me on [GitTip](https://www.gittip.com/alexgorbatchev/). I've spend days developing and grooming this module and hope to spend more time. If you have bitcoin, please use the QR code or this wallet address [`1CZyBREeHTmy8C5zVGHZHPwqBuWFmEuUCQ`](https://blockchain.info/address/1CZyBREeHTmy8C5zVGHZHPwqBuWFmEuUCQ):
+
+## Installation
+
+    npm install crc
+
+## Running tests
+
+    $ npm install
+    $ npm test
+
+## Usage Example
+
+Calculate a CRC32:
+
+    var crc = require('crc');
+
+    crc.crc32('hello').toString(16);
+    # => "3610a686"
+
+Calculate a CRC32 of a file:
+
+    crc.crc32(fs.readFileSync('README.md', 'utf8')).toString(16);
+    # => "127ad531"
+
+Or using a `Buffer`:
+
+    crc.crc32(fs.readFileSync('README.md')).toString(16);
+    # => "127ad531"
+
+Incrementally calculate a CRC32:
+
+    value = crc32('one');
+    value = crc32('two', value);
+    value = crc32('three', value);
+    value.toString(16);
+    # => "09e1c092"
+
+## Thanks!
+

+## Installation
+
+```
+$ npm install fresh
+```
+
+## API
+
+```js
+var fresh = require('fresh')
+```
+
+### fresh(req, res)
+
+ Check freshness of `req` and `res` headers.
+
+ When the cache is "fresh" __true__ is returned,
+ otherwise __false__ is returned to indicate that
+ the cache is now stale.
+
+## Example
+
+```js
+var req = { 'if-none-match': 'tobi' };
+var res = { 'etag': 'luna' };
+fresh(req, res);
+// => false
+
+var req = { 'if-none-match': 'tobi' };
+var res = { 'etag': 'tobi' };
+fresh(req, res);
+// => true

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

+
+Execute a callback when a request closes, finishes, or errors.
+
+## Install
+
+```sh
+$ npm install on-finished
+```
+
+## API
+
+```js
+var onFinished = require('on-finished')
+```
+
+### onFinished(res, listener)
+
+Attach a listener to listen for the response to finish. The listener will
+be invoked only once when the response finished. If the response finished
+to to an error, the first argument will contain the error. If the response
+has already finished, the listener will be invoked.
+
+Listening to the end of a response would be used to close things associated
+with the response, like open files.
+
+Listener is invoked as `listener(err, res)`.
+
+```js
+onFinished(res, function (err, res) {
+  // clean up open fds, etc.
+  // err contains the error is request error'd
+})
+```
+
+### onFinished(req, listener)
+
+Attach a listener to listen for the request to finish. The listener will
+be invoked only once when the request finished. If the request finished
+to to an error, the first argument will contain the error. If the request
+has already finished, the listener will be invoked.
+
+Listening to the end of a request would be used to know when to continue
+after reading the data.
+
+Listener is invoked as `listener(err, req)`.
+
+```js
+var data = ''
+
+req.setEncoding('utf8')
+res.on('data', function (str) {
+  data += str
+})
+
+onFinished(req, function (err, req) {
+  // data is read unless there is err
+})
+```
+
+### onFinished.isFinished(res)
+
+Determine if `res` is already finished. This would be useful to check and
+not even start certain operations if the response has already finished.
+
+### onFinished.isFinished(req)
+
+Determine if `req` is already finished. This would be useful to check and
+not even start certain operations if the request has already finished.
+
+### Example
+
+The following code ensures that file descriptors are always closed
+once the response finishes.
+
+```js
+var destroy = require('destroy')
+var http = require('http')
+var onFinished = require('on-finished')
+
+http.createServer(function onRequest(req, res) {
+  var stream = fs.createReadStream('package.json')
+  stream.pipe(res)
+  onFinished(res, function (err) {
+    destroy(stream)
+  })
+})
+```

+

+Get the first event in a set of event emitters and event pairs,

+then clean up after itself.

+

+## Install

+

+```sh

+$ npm install ee-first

+```

+

+## API

+

+```js

+var first = require('ee-first')

+```

+

+### first(arr, listener)

+

+Invoke `listener` on the first event from the list specified in `arr`. `arr` is

+an array of arrays, with each array in the format `[ee, ...event]`. `listener`

+will be called only once, the first time any of the given events are emitted. If

+`error` is one of the listened events, then if that fires first, the `listener`

+will be given the `err` argument.

+

+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the

+first argument emitted from an `error` event, if applicable; `ee` is the event

+emitter that fired; `event` is the string event name that fired; and `args` is an

+array of the arguments that were emitted on the event.

+

+```js

+var ee1 = new EventEmitter()

+var ee2 = new EventEmitter()

+

+first([

+  [ee1, 'close', 'end', 'error'],

+  [ee2, 'error']

+], function (err, ee, event, args) {

+  // listener invoked

+})

+```

+

+#### .cancel()

+

+The group of listeners can be cancelled before being invoked and have all the event

+listeners removed from the underlying event emitters.

+

+```js

+var thunk = first([

+  [ee1, 'close', 'end', 'error'],

+  [ee2, 'error']

+], function (err, ee, event, args) {

+  // listener invoked

+})

+

+// cancel and clean up

+thunk.cancel()

+```
