+/* GTK Demo
+ *
+ * GTK Demo is a collection of useful examples to demonstrate
+ * GTK widgets and features. It is a useful example in itself.
+ *
+ * You can select examples in the sidebar or search for them by
+ * typing a search term. Double-clicking or hitting the “Run” button
+ * will run the demo. The source code and other resources used in the
+ * demo are shown in this area.
+ *
+ * You can also use the GTK Inspector, available from the menu on the
+ * top right, to poke at the running demos, and see how they are put
+ * together.
