+[Vinyl][vinyl] adapter for the file system.
+
+## What is Vinyl?
+
+[Vinyl][vinyl] is a very simple metadata object that describes a file. When you think of a file, two attributes come to mind: `path` and `contents`. These are the main attributes on a [Vinyl][vinyl] object. A file does not necessarily represent something on your computer’s file system. You have files on S3, FTP, Dropbox, Box, CloudThingly.io and other services. [Vinyl][vinyl] can be used to describe files from all of these sources.
+
+## What is a Vinyl Adapter?
+
+While Vinyl provides a clean way to describe a file, we now need a way to access these files. Each file source needs what we call a "Vinyl adapter". A Vinyl adapter simply exposes a `src(globs)` and a `dest(folder)` method. Each return a stream. The `src` stream produces Vinyl objects, and the `dest` stream consumes Vinyl objects. Vinyl adapters can expose extra methods that might be specific to their input/output medium, such as the `symlink` method `vinyl-fs` provides.
+
+## Usage
+
+```javascript
+var map = require('map-stream');
+var vfs = require('vinyl-fs');
+
+var log = function(file, cb) {
+  console.log(file.path);
+  cb(null, file);
+};
+
+vfs.src(['./js/**/*.js', '!./js/vendor/*.js'])
+  .pipe(map(log))
+  .pipe(vfs.dest('./output'));
+```
+
+## API
+
+### `src(globs[, options])`
+
+Takes a glob string or an array of glob strings as the first argument and an options object as the second.
+Returns a stream of [vinyl] `File` objects.
+
+__Note: UTF-8 BOM will be removed from all UTF-8 files read with `.src` unless disabled in the options.__
+
+#### Globs
+
+Globs are executed in order, so negations should follow positive globs.
+
+For example:
+
+```js
+fs.src(['!b*', '*'])
+```
+
+would not exclude any files, but the following would exclude all files starting with "b":
+
+```js
+fs.src(['*', '!b*'])
+```
+
+#### Options
+
+- Values passed to the options must be of the expected type, otherwise they will be ignored.
+- All options can be passed a function instead of a value. The function will be called with the [vinyl] `File` object as its only argument and must return a value of the expected type for that option.
+
+##### `options.buffer`
+
+Whether or not you want to buffer the file contents into memory. Setting to `false` will make `file.contents` a paused Stream.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.read`
+
+Whether or not you want the file to be read at all. Useful for stuff like removing files. Setting to `false` will make `file.contents = null` and will disable writing the file to disk via `.dest()`.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.since`
+
+Only streams files that have been modified since the time specified.
+
+Type: `Date` or `Number`
+
+Default: `undefined`
+
+##### `options.removeBOM`
+
+Causes the BOM to be removed on UTF-8 encoded files. Set to `false` if you need the BOM for some reason.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.sourcemaps`
+
+Enables sourcemap support on files passed through the stream.  Will load inline sourcemaps and resolve sourcemap links from files.
+
+Type: `Boolean`
+
+Default: `false`
+
+##### `options.resolveSymlinks`
+
+Whether or not to recursively resolve symlinks to their targets. Set to `false` to preserve them as symlinks and make `file.symlink` equal the original symlink's target path.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.dot`
+
+Whether or not you want globs to match on dot files (e.g. `.gitignore`).
+
+__Note: This option is not resolved from a function because it is passed verbatim to node-glob.__
+
+Type: `Boolean`
+
+Default: `false`
+
+##### other
+
+Any glob-related options are documented in [glob-stream] and [node-glob] and are forwarded verbatim.
+
+### `dest(folder[, options])`
+
+Takes a folder path string or a function as the first argument and an options object as the second. If given a function, it will be called with each [vinyl] `File` object and must return a folder path.
+Returns a stream that accepts [vinyl] `File` objects, writes them to disk at the folder/cwd specified, and passes them downstream so you can keep piping these around.
+
+Once the file is written to disk, an attempt is made to determine if the `stat.mode`, `stat.mtime` and `stat.atime` of the [vinyl] `File` object differ from the file on the filesystem.
+If they differ and the running process owns the file, the corresponding filesystem metadata is updated.
+If they don't differ or the process doesn't own the file, the attempt is skipped silently.
+__This functionality is disabled on Windows operating systems or any other OS that doesn't support `process.getuid` or `process.geteuid` in node. This is due to Windows having very unexpected results through usage of `fs.fchmod` and `fs.futimes`.__
+
+__Note: The `fs.futimes()` method internally converts `stat.mtime` and `stat.atime` timestamps to seconds; this division by `1000` may cause some loss of precision in 32-bit Node.js.__
+
+If the file has a `symlink` attribute specifying a target path, then a symlink will be created.
+
+__Note: The file will be modified after being written to this stream.__
+  - `cwd`, `base`, and `path` will be overwritten to match the folder.
+  - `stat` will be updated to match the file on the filesystem.
+  - `contents` will have it's position reset to the beginning if it is a stream.
+
+#### Options
+
+- Values passed to the options must be of the expected type, otherwise they will be ignored.
+- All options can be passed a function instead of a value. The function will be called with the [vinyl] `File` object as its only argument and must return a value of the expected type for that option.
+
+##### `options.cwd`
+
+The working directory the folder is relative to.
+
+Type: `String`
+
+Default: `process.cwd()`
+
+##### `options.mode`
+
+The mode the files should be created with. This option is only resolved if the [vinyl] `File` is not symbolic.
+
+Type: `Number`
+
+Default: The `mode` of the input file (`file.stat.mode`) if any, or the process mode if the input file has no `mode` property.
+
+##### `options.dirMode`
+
+The mode directories should be created with.
+
+Type: `Number`
+
+Default: The process `mode`.
+
+##### `options.overwrite`
+
+Whether or not existing files with the same path should be overwritten.
+
+Type: `Boolean`
+
+Default: `true` (always overwrite existing files)
+
+##### `options.append`
+
+Whether or not new data should be appended after existing file contents (if any).
+
+Type: `Boolean`
+
+Default: `false` (always replace existing contents, if any)
+
+##### `options.sourcemaps`
+
+Enables sourcemap support on files passed through the stream.  Will write inline soucemaps if specified as `true`.
+Specifying a `String` path will write external sourcemaps at the given path.
+
+Examples:
+
+```js
+// Write as inline comments
+vfs.dest('./', { sourcemaps: true });
+
+// Write as files in the same folder
+vfs.dest('./', { sourcemaps: '.' });
+```
+
+Type: `Boolean` or `String`
+
+Default: `undefined` (do not write sourcemaps)
+
+##### `options.relativeSymlinks`
+
+When creating a symlink, whether or not the created symlink should be relative. If `false`, the symlink will be absolute.
+
+__Note: This option will be ignored if a `junction` is being created, as they must be absolute.__
+
+Type: `Boolean`
+
+Default: `false`
+
+##### `options.useJunctions`
+
+When creating a symlink, whether or not a directory symlink should be created as a `junction`.
+This option is only relevant on Windows and ignored elsewhere. Please refer to the [Symbolic Links on Windows][symbolic-caveats] section below.
+
+Type: `Boolean`
+
+Default: `true`
+
+### `symlink(folder[, options])`
+
+Takes a folder path string or a function as the first argument and an options object as the second. If given a function, it will be called with each [vinyl] `File` object and must return a folder path.
+Returns a stream that accepts [vinyl] `File` objects, creates a symbolic link (i.e. symlink) at the folder/cwd specified, and passes them downstream so you can keep piping these around.
+
+__Note: The file will be modified after being written to this stream.__
+  - `cwd`, `base`, and `path` will be overwritten to match the folder.
+  - `stat` will be updated to match the symlink on the filesystem.
+  - `contents` will be set to `null`.
+  - `symlink` will be added or replaced to be the original path.
+
+__Note: On Windows, directory links are created using Junctions by default. Use the `useJunctions` option to disable this behavior.__
+
+#### Options

+- Values passed to the options must be of the expected type, otherwise they will be ignored.
+- All options can be passed a function instead of a value. The function will be called with the [vinyl] `File` object as its only argument and must return a value of the expected type for that option.
+
+##### `options.cwd`
+

+
+Type: `String`
+
+Default: `process.cwd()`
+
+##### `options.dirMode`
+
+The mode directories should be created with.
+
+Type: `Number`
+
+Default: The process mode.
+
+##### `options.overwrite`
+
+Whether or not existing files with the same path should be overwritten.
+
+Type: `Boolean`
+
+Default: `true` (always overwrite existing files)
+
+##### `options.relativeSymlinks`
+
+Whether or not the created symlinks should be relative. If `false`, the symlink will be absolute.
+
+__Note: This option will be ignored if a `junction` is being created, as they must be absolute.__
+
+Type: `Boolean`
+
+Default: `false`
+
+##### `options.useJunctions`
+
+When creating a symlink, whether or not a directory symlink should be created as a `junction`.
+This option is only relevant on Windows and ignored elsewhere. Please refer to the [Symbolic Links on Windows][symbolic-caveats] section below.
+
+Type: `Boolean`
+
+Default: `true`
+
+#### Symbolic Links on Windows
+
+When creating symbolic links on Windows, we pass a `type` argument to Node's
+`fs` module which specifies the kind of target we link to (one of `'file'`,
+`'dir'` or `'junction'`). Specifically, this will be `'file'` when the target
+is a regular file, `'junction'` if the target is a directory, or `'dir'` if
+the target is a directory and the user overrides the `useJunctions` option
+default.
+
+However, if the user tries to make a "dangling" link (pointing to a non-existent
+target) we won't be able to determine automatically which type we should use.
+In these cases, `vinyl-fs` will behave slightly differently depending on
+whether the dangling link is being created via `symlink()` or via `dest()`.
+
+For dangling links created via `symlink()`, the incoming vinyl represents the
+target and so we will look to its stats to guess the desired type. In
+particular, if `isDirectory()` returns false then we'll create a `'file'` type
+link, otherwise we will create a `'junction'` or a `'dir'` type link depending
+on the value of the `useJunctions` option.
+
+For dangling links created via `dest()`, the incoming vinyl represents the link -
+typically read off disk via `src()` with the `resolveSymlinks` option set to
+false. In this case, we won't be able to make any reasonable guess as to the
+type of link and we default to using `'file'`, which may cause unexpected behavior
+if you are creating a "dangling" link to a directory. It is advised to avoid this
+scenario.
