6 * Revision 1.16 2002-01-22 10:54:46 adam
7 * MARC decode fix. Attribute set fix for scan in server. Prox logging.
9 * Revision 1.15 2001/10/29 09:17:19 adam
10 * New function marc_display_exl - used by YAZ client. Server returns
11 * bad record on position 98 (for testing).
13 * Revision 1.14 2001/10/23 21:00:20 adam
14 * Old Z39.50 codecs gone. Added ZOOM. WRBUF MARC display util.
16 * Revision 1.13 2001/10/15 19:36:48 adam
17 * New function marc_display_wrbuf.
19 * Revision 1.12 2000/10/02 11:07:44 adam
20 * Added peer_name member for bend_init handler. Changed the YAZ
21 * client so that tcp: can be avoided in target spec.
23 * Revision 1.11 2000/02/29 13:44:55 adam
24 * Check for config.h (currently not generated).
26 * Revision 1.10 2000/02/05 10:47:19 adam
27 * Identifier-length and indicator-lenght no longer set to 2 (forced).
29 * Revision 1.9 1999/12/21 16:24:48 adam
30 * More robust ISO2709 handling (in case of real bad formats).
