 The Wayland display server is a minimal graphics server which relies on
 the kernel for modesetting, batchbuffer submission, and hardware
 initialization. It leaves window management and most desktop policy to
 clients and their toolkit libraries. Everything is direct rendered and
 composited. X11 protocol is not supported.
 .
 This package provides headers and development files for the Wayland
 compositor.
