+ * Revision 1.38 1996/04/12 07:02:23 adam
+ * File update of single files.
+ *
+ * Revision 1.37 1996/03/26 16:01:13 adam

+ *
+ * Revision 1.34 1995/12/11 11:43:29 adam
+ * Locking based on fcntl instead of flock.
+ * Setting commitEnable removed. Command line option -n can be used to
+ * prevent commit if commit setting is defined in the configuration file.
+ *
+ * Revision 1.33 1995/12/08 16:22:53 adam
+ * Work on update while servers are running. Three lock files introduced.
