- * Revision 1.5  1995-03-08 12:12:10  quinn
+ * Revision 1.17  2001-06-26 12:14:15  adam
+ * When BER decoding a null byte is appended to the OCTET buffer.

+ * Revision 1.15  2000/01/31 13:15:21  adam
+ * Removed uses of assert(3). Cleanup of ODR. CCL parser update so

+ * 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.
