# LAF OS Library
`os` is an abstraction layer to access in different way the Operating
System graphics interface. We have our own implementation to create
windows and handle mouse/keyboard input. The graphics are rendered
using the [Skia](https://skia.org/) library.
* Minimum Windows platform: Windows Vista
