    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/datasets
```

</section>

<section class="usage">

## Usage

```javascript
var datasets = require( '@stdlib/datasets' );
```

#### datasets( name\[, options] )

Returns standard library datasets.

```javascript
var data = datasets( 'MONTH_NAMES_EN' );
/* returns
    [
        'January',
        'February',
        'March',
        'April',
        'May',
        'June',
        'July',
        'August',
        'September',
        'October',
        'November',
        'December'
    ]
*/
```

The function forwards provided `options` to the dataset interface specified by `name`. 

```javascript
var opts = {
    'data': 'cities'
};

var data = datasets( 'MINARD_NAPOLEONS_MARCH', opts );
/* returns
    [
        {'lon': 24,'lat': 55,'city': 'Kowno',
        {'lon': 25.3,'lat': 54.7,'city': 'Wilna',

### Usage

```text
Usage: datasets [options] [--name=<name>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --name name           Dataset name.

<section class="notes">

### Notes

-   Dataset specific options should follow two hyphen characters `--` in order to indicate that those options should not be parsed as normal command-line options.

</section>

<!-- /.notes -->

<section class="examples">

### Examples

```bash
$ datasets --name MONTH_NAMES_EN
January
February
March
...
```

Use two hyphen characters `--` to delineate dataset specific options.

```bash
$ datasets --name MINARD_NAPOLEONS_MARCH -- --data army
lon,lat,size,direction,division
24.0,54.9,340000,A,1
24.5,55.0,340000,A,1
25.5,54.5,340000,A,1
