+Send is a library for streaming files from the file system as a http response
+supporting partial responses (Ranges), conditional-GET negotiation (If-Match,
+If-Unmodified-Since, If-None-Match, If-Modified-Since), high test coverage,
+and granular events which may be leveraged to take appropriate actions in your
+application or framework.

+
+## 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):
+
+```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
+
+##### acceptRanges
+
+Enable or disable accepting ranged requests, defaults to true.
+Disabling this will not send `Accept-Ranges` and ignore the contents
+of the `Range` request header.
+
+##### cacheControl
+
+Enable or disable setting `Cache-Control` response header, defaults to
+true. Disabling this will ignore the `immutable` and `maxAge` 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.
+
+##### end
+
+Byte offset at which the stream ends, defaults to the length of the file
+minus 1. The end is inclusive in the stream, meaning `end: 3` will include
+the 4th byte in the stream.
+
+##### 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.
+
+##### immutable
+
+Enable or disable the `immutable` directive in the `Cache-Control` response
+header, defaults to `false`. If set to `true`, the `maxAge` option should
+also be specified to enable caching. The `immutable` directive will prevent
+supported clients from making conditional requests during the life of the
+`maxAge` option to check if the file has changed.
+
+##### 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`.
+
+##### start
+
+Byte offset at which the stream starts, defaults to 0. The start is inclusive,
+meaning `start: 2` will include the 3rd byte in the stream.
+
+#### Events
+
+The `SendStream` is an event emitter and will emit the following events:
+
+  - `error` an error occurred `(err)`
+  - `directory` a directory was requested `(res, path)`
+  - `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)`.
+
+### .mime
+
+The `mime` export is the global instance of of the
+[`mime` npm module](https://www.npmjs.com/package/mime).
+
+This is used to configure the MIME types that are associated with file extensions
+as well as other options for how to resolve the MIME type of a file (like the
+default type to use for an unknown file extension).
+
+## 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
+
+### Serve a specific file
+
+This simple example will send a specific file to all requests.
+
+```js
+var http = require('http')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, '/path/to/index.html')
+    .pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Serve all files from a directory
+
+This simple example will just serve up all the files in a
+given directory as the top-level. For example, a request
+`GET /foo.txt` will send back `/www/public/foo.txt`.
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, { root: '/www/public' })
+    .pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Custom file types
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+// Default unknown types to text/plain
+send.mime.default_type = 'text/plain'
+
+// Add a custom type
+send.mime.define({
+  'application/x-my-type': ['x-mt', 'x-mtt']
+})
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, { root: '/www/public' })
+    .pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Custom directory index view
+
+This is a example of serving up a structure of directories with a
+custom function to render a listing of a directory.
+
+```js
+var http = require('http')
+var fs = require('fs')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+// Transfer arbitrary files from within /www/example.com/public/*
+// with a custom handler for directory listing
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, { index: false, root: '/www/public' })
+    .once('directory', directory)
+    .pipe(res)
+})
+
+server.listen(3000)
+
+// Custom directory handler
+function directory (res, path) {
+  var stream = this
+
+  // redirect to trailing slash for consistent url
+  if (!stream.hasTrailingSlash()) {
+    return stream.redirect(path)
+  }
+
+  // get directory list
+  fs.readdir(path, function onReaddir (err, list) {
+    if (err) return stream.error(err)
+
+    // render an index for the directory
+    res.setHeader('Content-Type', 'text/plain; charset=UTF-8')
+    res.end(list.join('\n') + '\n')
+  })
+}
+```
+
+### Serving from a root directory with custom error-handling
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+var server = http.createServer(function onRequest (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, parseUrl(req).pathname, { root: '/www/public' })
+    .on('error', error)
+    .on('directory', redirect)
+    .on('headers', headers)
+    .pipe(res)
+})
+
+server.listen(3000)
+```

+
+
+
+A tiny node.js debugging utility modelled after node core's debugging technique.
+
+**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+ Note that PowerShell uses different syntax to set environment variables.
+
+ ```cmd
+ $env:DEBUG = "*,-not_this"
+  ```
+
+Then, run the program to be debugged as usual.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+  If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Environment Variables
+
+  When running through Node.js, you can set a few environment variables that will
+  change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+  __Note:__ The environment variables beginning with `DEBUG_` end up being
+  converted into an Options object that gets used with `%o`/`%O` formatters.
+  See the Node.js documentation for
+  [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+  for the complete list.
+
+## Formatters
+
+
+  Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+### Custom formatters
+
+  You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+## Browser support
+  You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+  or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+  if you don't want to build it yourself.
+
+  Debug's enable state is currently persisted by `localStorage`.
+  Consider the situation shown below where you have `worker:a` and `worker:b`,
+  and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example _stdout.js_:
+
+```js
+var debug = require('debug');

+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`
