+# Ridiculously simple test of the os.startfile function for Windows.
+#
+# empty.vbs is an empty file (except for a comment), which does
+# nothing when run with cscript or wscript.
+#
+# A possible improvement would be to have empty.vbs do something that
+# we can detect here, to make sure that not only the os.startfile()
+# call succeeded, but also the the script actually has run.
