The Nano-X Window System is an Open Source project aimed at bringing the features of modern graphical windowing environments to smaller devices and platforms. Nano-X allows applications to be built and tested on the Linux desktop, as well as cross-compiled for the target device. The Nano-X Window System was previously named Microwindows, but has been renamed due to conflicts with Microsoft’s Windows trademark. There are two APIs implemented in the system, a Win32 API and an Xlib-like API.
