+# This procedure displays a dialog box, waits for a button in the dialog
+# to be invoked, then returns the index of the selected button. If the
+# dialog somehow gets destroyed, -1 is returned.
+#
+# Arguments:
+# w - Window to use for dialog top-level.
+# title - Title to display in dialog's decorative frame.
+# text - Message to display in dialog.
+# bitmap - Bitmap to display in dialog (empty string means none).
+# default - Index of button that is to display the default ring
+# (-1 means none).
+# args - One or more strings to display in buttons across the
+# bottom of the dialog box.
