+      Glade is a RAD tool to enable quick & easy development of user
+      interfaces for the GTK+ toolkit and the GNOME desktop
+      environment, released under the GNU GPL License.
+
+      The user interfaces designed in Glade are saved as XML, and by
+      using the libglade library these can be loaded by applications
+      dynamically as needed.
+
+      By using libglade, Glade XML files can be used in numerous
+      programming languages including C, C++, Java, Perl, Python, C#,
+      Pike, Ruby, Haskell, Objective Caml and Scheme.  Adding support
+      for other languages is easy too.
