- * Revision 1.16 1999-09-07 07:19:21 adam
- * Work on character mapping. Implemented replace rules.
- *
- * Revision 1.15 1999/05/26 07:49:14 adam
- * C++ compilation.
- *
- * Revision 1.14 1998/10/13 20:09:18 adam
- * Changed call to readconf_line.
- *
- * Revision 1.13 1997/10/27 14:33:06 adam
- * Moved towards generic character mapping depending on "structure"
- * field in abstract syntax file. Fixed a few memory leaks. Fixed
- * bug with negative integers when doing searches with relational
- * operators.
- *
- * Revision 1.12 1997/09/05 15:30:11 adam
- * Changed prototype for chr_map_input - added const.
- * Added support for C++, headers uses extern "C" for public definitions.
- *
- * Revision 1.11 1997/09/05 09:52:32 adam
- * Extra argument added to function chr_read_maptab (tab path).
- *
- * Revision 1.10 1997/07/01 13:01:08 adam
- * Bug fix in routine find_entry: didn't take into account the len arg.
- *
- * Revision 1.9 1996/10/29 13:48:14 adam
- * Updated to use zebrautl.h instead of alexutil.h.
- *
- * Revision 1.8 1996/10/18 12:39:23 adam
- * Uses LOG_DEBUG instead of LOG_WARN for "Character map overlap".
- *
- * Revision 1.7 1996/06/06 12:08:56 quinn
- * Fixed bug.
