libwayland-doc 1.18.0-2~exp1.1 (s390x binary) in ubuntu groovy

 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.
 .
 This package contains the documentation for the Wayland libraries.
 Non-developers likely have little use for this package.
