+  <description>gtk-vnc is a project providing client side APIs for the
+RFB protocol / VNC remote desktop technology.
+
+It is built using coroutines allowing it to be completely
+asynchronous while remaining single threaded. It provides
+two core C libraries, libgvnc for interacting with the core
+RFB protocol and libgtk-vnc for a GTK display widget.
+
+There is a traditional Python binding built on PyGTK, and
+evolving support for arbitrary languages via the GObject
+Introspection system.</description>
