- * Revision 1000.1 2004/04/12 17:16:14 gouriano
- * PRODUCTION: UPGRADED [CATCHUP_003] Dev-tree R1.8
- *
- * Revision 1.8 2004/02/25 19:45:47 gouriano
- * Made it possible to define DEFAULT for data members of type REAL
- *
- * Revision 1.7 2002/09/26 16:57:31 vasilche
- * Added flag for compatibility with asntool
- *
- * Revision 1.6 2001/06/11 14:34:58 grichenk
- * Added support for numeric tags in ASN.1 specifications and data streams.
- *
- * Revision 1.5 2000/11/15 20:34:43 vasilche
- * Added user comments to ENUMERATED types.
- * Added storing of user comments to ASN.1 module definition.
- *
- * Revision 1.4 2000/11/14 21:41:13 vasilche
- * Added preserving of ASN.1 definition comments.
- *
- * Revision 1.3 2000/08/25 15:58:46 vasilche
- * Renamed directory tool -> datatool.
- *
- * Revision 1.2 2000/04/07 19:26:09 vasilche
- * Added namespace support to datatool.
- * By default with argument -oR datatool will generate objects in namespace
- * NCBI_NS_NCBI::objects (aka ncbi::objects).
- * Datatool's classes also moved to NCBI namespace.
- *
- * Revision 1.1 2000/02/01 21:46:19 vasilche
- * Added CGeneratedChoiceTypeInfo for generated choice classes.
- * Removed CMemberInfo subclasses.
- * Added support for DEFAULT/OPTIONAL members.
- * Changed class generation.
- * Moved datatool headers to include/internal/serial/tool.
