+      Wayland is a project to define a protocol for a compositor to talk to its
+      clients as well as a library implementation of the protocol.
+      The wayland protocol is essentially only about input handling and buffer
+      management, but also handles drag and drop, selections, window management
+      and other interactions that must go through the compositor (but not
+      rendering).
