wayland-info is a utility for displaying information about the Wayland
protocols supported by a Wayland compositor.

It can be used to check which Wayland protocols and versions are 
advertised by the Wayland compositor.

wayland-info also provides additional information for a subset of 
Wayland protocols it knows about, namely Linux DMABUF, 
presentation time, tablet and XDG output protocols.
