+
+> Gulp symlink module
+
+# Installation
+
+```
+npm install gulp-sym --save-dev {--production}
+```
+
+# Usage
+
+## Simple example
+
+```javascript
+var symlink = require('gulp-sym')
+
+gulp
+	.src('source')
+	.pipe(symlink('path/to/link'))
+	//note that it'll return source streams not the symlink ones
+
+```
+
+## Advanced example
+
+```javascript
+var symlink = require('gulp-sym')
+  , p = require('path')
+  , File = require('gulp-util').File
+
+gulp
+	.src(['path/**/to/some/dir/', '!path/example/to/some/dir'])
+	//source is a vinyl instance
+	.pipe(symlink(function(source) {
+
+		//for example link source is my/dest/path/dirname where dirname matches the glob pattern
+		return p.join('my/dest/path', source.relative.split(p.sep)[0])
+
+		//you might also return a vinyl instance if you wanted a different cwd
+		return new File({cwd: '/home', path: './symlink'})
+
+	}, { force: true })) //use force option to replace existant
+```
+
+## Options
+
+- `force` (bool): force overwrite symlink
+- `relative` (bool): your link will be relative
+
+### /!\ Don't do this ...
+
+If you're working on more than 1 source, use a function or an array to specify the destination path so `gulp-sym` doesn't override the previous symlink!
+
+Here is a counterexample, `dest` will be a link to `source/path/two` and the first one will not have any symlink!
+
+```javascript
+gulp
+	.src(['source/path/one', 'source/path/two'])
+	.pipe(symlink('dest', {force: true})) //bad shit WILL happen
+	
+```
+
+### ... but this
+
+That's how it should be:
+```javascript
+gulp
+	.src(['source/path/one', 'source/path/two'])
+	.pipe(symlink(['dest/one', 'dest/two']))
+	
+```
+or through a function that'll be called on each source 
+
+```javascript
+gulp
+	.src(['source/path/one', 'source/path/two'])
+	.pipe(symlink(function(source) {
+		return p.resolve(source.path, '../../dest', p.basename(source.path))
+	})
+
+```
+
+It's intendend behavior and api will not change for this, I could warn the user in this case - to be discussed.
+
+# Why?
+
+I'm aware that there is another [symlink](https://github.com/ben-eb/gulp-symlink) module for gulp but as of v0.1.0 it didn't fit my needs and seems to get messy (absolute/relative). In this plugin, `paths` are always absolute and resolves from the `cwd` that you might change by passing a [vinyl](https://github.com/wearefractal/vinyl) instance to the destination function.
+
+[gulp-symlink](https://github.com/ben-eb/gulp-symlink) :
+- has no force option to replace existing link
+- uses [fs.symlink twice](https://github.com/ben-eb/gulp-symlink/blob/master/index.js#L54) instead of using `fs.exists`. I'm aware of the nodejs docs specifying that `fs.exists` is there on an historical purpose only but why shouldn't we use it?
+- doesn't use the specified type option mentioned in the [nodejs docs](http://nodejs.org/api/fs.html#fs_fs_symlink_srcpath_dstpath_type_callback) (windows only)
+- has no test on symlinking directories (maybe why tests are good to go on windows)
+- has bad support on multiple sources (at the moment)

+> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
+
+
+## Install
+
+```sh
+$ npm install --save ansi-regex
+```
+
+
+## Usage
+
+```js
+var ansiRegex = require('ansi-regex');
+
+ansiRegex().test('\u001b[4mcake\u001b[0m');
+//=> true
+
+ansiRegex().test('cake');
+//=> false
+
+'\u001b[4mcake\u001b[0m'.match(ansiRegex());
+//=> ['\u001b[4m', '\u001b[0m']
+```
+
+*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

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

+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`

+## Information
+
+<table>
+<tr> 
+<td>Package</td><td>gulp-util</td>
+</tr>
+<tr>
+<td>Description</td>
+<td>Utility functions for gulp plugins</td>
+</tr>
+<tr>
+<td>Node Version</td>
+<td>>= 0.9</td>
+</tr>
+</table>
+
+## Usage
+
+```javascript
+var gutil = require('gulp-util');
+
+gutil.log('stuff happened', 'Really it did', gutil.colors.cyan('123'));
+gutil.beep();
+
+gutil.replaceExtension('file.coffee', '.js'); // file.js
+
+var opt = {
+  name: 'todd',
+  file: someGulpFile
+};
+gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
+```
+
+### log(msg...)
+
+Logs stuff. Already prefixed with [gulp] and all that. Use the right colors for values. If you pass in multiple arguments it will join them by a space.
+
+```
+values (files, module names, etc.) = magenta
+numbers (times, counts, etc) = cyan
+```
+
+### replaceExtension(path, newExtension)
+
+Replaces a file extension in a path. Returns the new path.
+
+### isStream(obj)
+
+Returns true or false if an object is a stream.
+
+### isBuffer(obj)
+
+Returns true or false if an object is a Buffer.
+
+### template(string[, data])
+
+This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
+
+## new File(obj)
+
+This is just [vinyl](https://github.com/wearefractal/vinyl)
+
+```javascript
+var file = new gutil.File({
+  base: join(__dirname, './fixtures/'),
+  cwd: __dirname,
+  path: join(__dirname, './fixtures/test.coffee')
+});
+```
+
+## noop()
+
+Returns a stream that does nothing but pass data straight through.
+
+```javascript
+// gulp should be called like this :
+// $ gulp --type production
+gulp.task('scripts', function() {
+  gulp.src('src/**/*.js')
+    .pipe(concat('script.js'))
+    .pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
+    .pipe(gulp.dest('dist/');
+});
+```
+
+## buffer(cb)
+
+This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
+
+Returns a stream that can be piped to.
+
+The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
+
+Callback is optional and receives two arguments: error and data
+
+```javascript
+gulp.src('stuff/*.js')
+  .pipe(gutil.buffer(function(err, files){
+  
+  });
+```
+
+## new PluginError(pluginName, message[, options])
+
+- pluginName should be the module name of your plugin
+- message can be a string or an existing error
+- By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
+- If you pass an error in as the message the stack will be pulled from that, otherwise one will be created.
+- Note that if you pass in a custom stack string you need to include the message along with that.
+
+These are all acceptable forms of instantiation:
+
+```javascript
+var err = new gutil.PluginError('test', {
+  message: 'something broke'
+});
+
+var err = new gutil.PluginError({
+  plugin: 'test',
+  message: 'something broke'
+});
+
+var err = new gutil.PluginError('test', 'something broke');
+
+var err = new gutil.PluginError('test', 'something broke', {showStack: true});
+
+var existingError = new Error('OMG');
+var err = new gutil.PluginError('test', existingError, {showStack: true});
+```

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

+***Node-core streams for userland***
+
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

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

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

+
+### isNull()
+
+Returns true if file.contents is null.
+
+### clone()
+
+Returns a new File object with all attributes cloned.
+
+### pipe(stream[, opt])
+
+If file.contents is a Buffer, it will write it to the stream.
+
+If file.contents is a Stream, it will pipe it to the stream.
+
+If file.contents is null, it will do nothing.
+
+If opt.end is true, the destination stream will not be ended (same as node core).
+
+Returns the stream.
+
+### inspect()
+
+Returns a pretty String interpretation of the File. Useful for console.log.
+
+### relative
+
+Returns path.relative for the file base and file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.relative); // file.coffee
+```

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