6 * Revision 1.17 2000-01-31 13:15:21 adam
7 * Removed uses of assert(3). Cleanup of ODR. CCL parser update so
8 * that some characters are not surrounded by spaces in resulting term.
11 * Revision 1.16 1999/11/30 13:47:11 adam
12 * Improved installation. Moved header files to include/yaz.
14 * Revision 1.15 1999/01/08 11:23:20 adam
15 * Added const modifier to some of the BER/ODR encoding routines.
17 * Revision 1.14 1998/02/11 11:53:34 adam
18 * Changed code so that it compiles as C++.

30 * License, documentation, and memory fixes
32 * Revision 1.9 1995/04/18 08:15:12 quinn
33 * Added dynamic memory allocation on encoding (whew). Code is now somewhat
