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