[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*'])
```
