## API
### osName(platform?, release?)
By default, the name of the current operating system is returned.
You can optionally supply a custom [`os.platform()`](https://nodejs.org/api/os.html#os_os_platform) and [`os.release()`](https://nodejs.org/api/os.html#os_os_release).
Check out [`getos`](https://github.com/wblankenship/getos) if you need the Linux distribution name.
