   <shortdesc xml:lang="en">Window and compositing manager based on Clutter</shortdesc>
+  <description>Mutter is a window and compositing manager that displays and
+manages your desktop via OpenGL. Mutter combines a sophisticated display engine
+using the Clutter toolkit with solid window-management logic inherited from the
+Metacity window manager.
+
+While Mutter can be used stand-alone, it is primarily intended to be used as
+the display core of a larger system such as GNOME Shell. For this reason,
+Mutter is very extensible via plugins, which are used both to add fancy visual
+effects and to rework the window management behaviors to meet the needs of the
+environment.</description>
