+# 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.
+
+# This file demonstrates the use of the tixDirTree widget -- you can
+# use it for the user to select a directory. For example, an installation
+# program can use the tixDirTree widget to ask the user to select the
+# installation directory for an application.
