+# Tix Demostration Program
+#
+# This sample program is structured in such a way so that it can be
+# executed from the Tix demo program "widget": it must have a
+# procedure called "RunSample". It should also have the "if" statment
+# at the end of this file so that it can be run as a standalone
+# program using tixwish.
+
+# Demonstrates how to use compound images to display icons in a canvas widget.
