  <name xml:lang="en">GNOME Shell</name>
  <shortdesc xml:lang="en">Next generation GNOME desktop shell</shortdesc>
+  <description>GNOME Shell provides core user interface functions for the GNOME 3
+desktop, like switching to windows and launching applications.
+GNOME Shell takes advantage of the capabilities of modern graphics
+hardware and introduces innovative user interface concepts to
+provide a visually attractive and easy to use experience.
+
+Tarball releases are provided largely for distributions to build
+packages. If you are interested in building GNOME Shell from source,
+we would recommend building from version control using the build
+script described at:
+
+ http://live.gnome.org/GnomeShell
+
+Not only will that give you the very latest version of this rapidly
+changing project, it will be much easier than get GNOME Shell and
+its dependencies to build from tarballs.</description>
