- * Revision 1.6 1995-03-17 10:17:41 quinn
+ * Revision 1.17 2001-06-26 12:14:15 adam
+ * When BER decoding a null byte is appended to the OCTET buffer.
+ *
+ * Revision 1.16 2000/02/29 13:44:55 adam
+ * Check for config.h (currently not generated).
+ *
+ * Revision 1.15 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 1.14 1999/11/30 13:47:11 adam
+ * Improved installation. Moved header files to include/yaz.
+ *
+ * Revision 1.13 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 1.12 1999/01/08 11:23:24 adam
+ * Added const modifier to some of the BER/ODR encoding routines.
+ *
+ * Revision 1.11 1998/02/11 11:53:34 adam
+ * Changed code so that it compiles as C++.
+ *
+ * Revision 1.10 1995/09/29 17:12:18 quinn
+ * Smallish
+ *
+ * Revision 1.9 1995/09/27 15:02:55 quinn
+ * Modified function heads & prototypes.
+ *
+ * Revision 1.8 1995/05/16 08:50:47 quinn
+ * License, documentation, and memory fixes
+ *
+ * Revision 1.7 1995/04/18 08:15:17 quinn
+ * Added dynamic memory allocation on encoding (whew). Code is now somewhat
+ * neater. We'll make the same change for decoding one day.
+ *
+ * Revision 1.6 1995/03/17 10:17:41 quinn
* Added memory management.
