- * options_func. options_func allows us to specify a different function
- * to interogate the command line arguments. The other members allow us
- * to pass the full service details accross to the service manager (CW).
- *
- *
- * Revision 1.46 1998/01/30 15:24:57 adam

- *
- * Revision 1.42 1997/10/27 14:03:02 adam
- * Added new member to statserver_options_block, pre_init, which
- * specifies a callback to be invoked after command line parsing and
- * before the server listens for the first time.
- *
- * Revision 1.41 1997/09/29 07:19:32 adam
- * Server library uses nmem_init/nmem_exit. The log prefix no longer

- * Revision 1.40 1997/09/17 12:10:41 adam
- * YAZ version 1.4.
- *
- * Revision 1.39 1997/09/09 10:10:19 adam
