*
- * Revision 1.3 2000/02/08 10:39:53 adam
- * Added a few functions to set name of operands, etc.
- *
- * Revision 1.2 2000/01/31 13:15:21 adam
- * Removed uses of assert(3). Cleanup of ODR. CCL parser update so
- * that some characters are not surrounded by spaces in resulting term.
- * ILL-code updates.
- *
- * Revision 1.1 1999/11/30 13:47:11 adam
- * Improved installation. Moved header files to include/yaz.
- *
- * Revision 1.9 1998/02/11 11:53:33 adam
- * Changed code so that it compiles as C++.
- *
- * Revision 1.8 1997/09/29 09:01:19 adam
- * Changed CCL parser to be thread safe. New type, CCL-parser, declared
- * and a create/destructor ccl_parser_create/ccl_parser_destroy has been
- * added.
- *
- * Revision 1.7 1997/09/01 08:49:47 adam
- * New windows NT/95 port using MSV5.0. To export DLL functions the
- * YAZ_EXPORT modifier was added. Defined in yconfig.h.
- *
- * Revision 1.6 1997/05/14 06:53:37 adam
- * C++ support.
- *
- * Revision 1.5 1997/04/30 08:52:08 quinn
- * Null
