+# This sample program is structured in such a way so that it can be
+# executed from the Tix demo program "tixwidgets": 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.
+
+# This file demonstrates how to use the TixTree widget to display
+# dynamic hierachical data (the files in the Unix file system)
