+     "Wayflan is a from-scratch Wayland communication library for Common Lisp.
+It makes a good-faith effort to mimic @code{libwayland} behavior not defined
+in the Wayland spec, to keep compatibility between the two libraries.
+
+Wayflan is not a compositor nor a GUI toolkit.  Its purpose is to parse Wayland
+protocol XML documents and exchange Wayland messages between other processes.
+
+Features:
+@itemize
+@item Client support
+@item All implementation done in Common Lisp from the socket up
+@item Enum values are translated into keywords
+@item Wayland protocol introspection
+@item ASDF component @code{:wayflan-client-impl} generates code from
+XML.  ASDF's extensible components make it possible to teach your program new
+protocols for Wayland without the need of a special build system.
+@end itemize")
