- * $Log: ber_bit.c,v $
- * Revision 1.11  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 1.10  1999/11/30 13:47:11  adam
- * Improved installation. Moved header files to include/yaz.
- *
- * Revision 1.9  1999/04/20 09:56:48  adam
- * Added 'name' paramter to encoder/decoder routines (typedef Odr_fun).
- * Modified all encoders/decoders to reflect this change.
- *
- * Revision 1.8  1999/01/08 11:23:21  adam
- * Added const modifier to some of the BER/ODR encoding routines.
- *
- * Revision 1.7  1995/09/29 17:12:16  quinn
- * Smallish
- *
- * Revision 1.6  1995/09/27  15:02:54  quinn
- * Modified function heads & prototypes.
- *
- * Revision 1.5  1995/05/16  08:50:43  quinn
- * License, documentation, and memory fixes
- *
- * Revision 1.4  1995/04/18  08:15:13  quinn
- * Added dynamic memory allocation on encoding (whew). Code is now somewhat
- * neater. We'll make the same change for decoding one day.
- *
- * Revision 1.3  1995/03/08  12:12:04  quinn
- * Added better error checking.
- *
- * Revision 1.2  1995/02/03  17:04:31  quinn
