The bare-bones internationalization library used by yargs.

Inspired by [i18n](https://www.npmjs.com/package/i18n).

## Examples

_simple string translation:_

```js
var __ = require('y18n').__

console.log(__('my awesome string %s', 'foo'))
```

output:

`my awesome string foo`

_pluralization support:_

```js
var __n = require('y18n').__n

console.log(__n('one fish %s', '%d fishes %s', 2, 'foo'))
```

output:

`2 fishes foo`

## JSON Language Files

The JSON language files should be stored in a `./locales` folder.
File names correspond to locales, e.g., `en.json`, `pirate.json`.

When strings are observed for the first time they will be
added to the JSON file corresponding to the current locale.

## Methods

### require('y18n')(config)

Create an instance of y18n with the config provided, options include:

* `directory`: the locale directory, default `./locales`.
* `updateFiles`: should newly observed strings be updated in file, default `true`.
* `locale`: what locale should be used.
* `fallbackToLanguage`: should fallback to a language-only file (e.g. `en.json`)
  be allowed if a file matching the locale does not exist (e.g. `en_US.json`),
  default `true`.
