10 * Revision 1.17 2002/04/04 20:49:46 adam
11 * New functions yaz_is_abspath, yaz_path_fopen_base
13 * Revision 1.16 1999/11/30 13:47:12 adam
14 * Improved installation. Moved header files to include/yaz.
16 * Revision 1.15 1999/10/21 12:06:29 adam
17 * Retrieval module no longer uses ctype.h - functions.
19 * Revision 1.14 1999/08/27 09:40:32 adam
20 * Renamed logf function to yaz_log. Removed VC++ project files.
22 * Revision 1.13 1998/10/13 16:09:52 adam
23 * Added support for arbitrary OID's for tagsets, schemas and attribute sets.
24 * Added support for multiple attribute set references and tagset references
25 * from an abstract syntax file.
26 * Fixed many bad logs-calls in routines that read the various
27 * specifications regarding data1 (*.abs,*.att,...) and made the messages
28 * consistent whenever possible.
29 * Added extra 'lineno' argument to function readconf_line.
31 * Revision 1.12 1998/02/23 10:57:09 adam
32 * Take care of integer data nodes as well in conversion.
34 * Revision 1.11 1998/02/11 11:53:35 adam
35 * Changed code so that it compiles as C++.
37 * Revision 1.10 1997/09/30 11:50:04 adam
38 * Added handler data1_get_map_buf that is used by data1_nodetomarc.
40 * Revision 1.9 1997/09/24 13:35:45 adam
41 * Added two members to data1_marctab to ease reading of weird MARC records.
43 * Revision 1.8 1997/09/17 12:10:37 adam
46 * Revision 1.7 1997/09/05 09:50:57 adam

50 * Added data1 to marc conversion with indicators.
52 * Revision 1.5 1997/09/04 13:48:04 adam
53 * Added data1 to marc conversion.
55 * Revision 1.4 1996/03/25 10:18:03 quinn
56 * Removed trailing whitespace from data elements
58 * Revision 1.3 1995/11/01 16:34:57 quinn
59 * Making data1 look for tables in data1_tabpath
61 * Revision 1.2 1995/11/01 13:54:48 quinn
