       Glade is a RAD tool to enable quick &amp; easy development of user interfaces
       for the GTK+ 3 toolkit and the GNOME desktop environment.

+    <_p>
       The user interfaces designed in Glade are saved as XML and these can be
       loaded by applications dynamically as needed by using GtkBuilder or used
       directly to define a new GtkWidget derived object class using
       Gtk+ new template feature.
     </p>

+<!-- To translators: AppData description third paragraph -->
+    <_p>
       By using GtkBuilder, Glade XML files can be used in numerous programming 
       languages including C, C++, C#, Vala, Java, Perl, Python,and others.
