Internal Program Version: wayland  1.23.1

Wayland is a protocol for a compositor to talk to its clients as well
as a C library implementation of that protocol. The compositor can be
a standalone display server running on Linux kernel modesetting and
evdev input devices, an X application, or a wayland client itself.
The clients can be traditional applications, X servers (rootless or
fullscreen) or other display servers.
