## Support

Platform.js has been tested in at least Adobe AIR 3.1, Chrome 5-21, Firefox 1-14, IE 6-9, Opera 9.25-12, Safari 3-6, Node.js 0.8.6, Narwhal 0.3.2, RingoJS 0.8, and Rhino 1.7RC5.

## Installation and usage

In a browser or Adobe AIR:

```html
<script src="platform.js"></script>
```

Via [npm](http://npmjs.org/):

```bash
npm install platform
```

In [Node.js](http://nodejs.org/) and [RingoJS](http://ringojs.org/):

```js
var platform = require('platform');
```

In [Rhino](http://www.mozilla.org/rhino/):

```js
load('platform.js');
```

In an AMD loader like [RequireJS](http://requirejs.org/):

```js
require({
  'paths': {
    'platform': 'path/to/platform'
  }
},
['platform'], function(platform) {
  console.log(platform.name);
});
```

Usage example:

```js
// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'
