libwayland-dev 1.16.0-1ubuntu1 (i386 binary) in ubuntu cosmic

 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 development headers for the Wayland libraries.
 Non-developers likely have little use for this package.
