+ * File update uses modify-time instead of change-time.
+ *
+ * Revision 1.6 1996/02/02 13:44:43 adam
+ * The public dictionary functions simply use char instead of Dict_char
+ * to represent search strings. Dict_char is used internally only.
+ *
+ * Revision 1.5 1996/01/17 14:54:44 adam
+ * Function dirs_rmdir uses dict_delete.
+ *
+ * Revision 1.4 1995/11/30 08:34:27 adam
+ * Started work on commit facility.
+ * Changed a few malloc/free to xmalloc/xfree.
+ *
+ * Revision 1.3 1995/11/20 16:59:45 adam
+ * New update method: the 'old' keys are saved for each records.
+ *
+ * Revision 1.2 1995/11/20 11:56:23 adam
* Work on new traversal.
