/* Modification History:
 * $Log: udanax.h,v $
 * Revision 1.7  2004/08/28 13:35:26  jrush
 * Catching up CVS to various incomplete versions on local disk.
 *
 * Revision 1.6  2002/07/14 08:29:43  jrush
 * Added include of nana.h and assert.h
 *
 * Revision 1.5  2002/05/28 03:51:13  jrush
 * Updated sources to comply with a GPL licensing.
 *
 * Revision 1.4  2002/04/13 14:08:35  jrush
 * Changed typedef of structs into just structs, for C++ style.
 *
 * Revision 1.3  2002/04/13 13:43:45  jrush
 * Added extern of Diskheader structure.
 *
 * Revision 1.2  2002/04/12 11:46:25  jrush
 * Major rearrangement of include contents, to reflect a hopefully more
 * logical layout as we refactor Udanax into classes.
 *
 * Revision 1.1  2002/04/12 09:32:51  jrush
 * Renamed xanadu.h to udanax.h
 *
 * Revision 1.9  2002/04/10 18:01:54  jrush
 * Renamed class typeisa to IStreamAddr.
 *
 * Revision 1.8  2002/04/09 21:45:46  jrush
 * Renamed class 'tumbler' to 'Tumbler', for consistency with Python sources,
 * and changed typeisa from typedef to a subclass, in preparation for cleaning
 * up the type/class tree.
 *
 * Revision 1.7  2002/04/06 17:05:57  jrush
 * Switched from referring to 'task' for a client connection to 'session',
 * and converted the typetask typedef/struct into a Session C++ class.
 *
 * Revision 1.6  2002/04/06 15:00:34  jrush
 * Changed INT to just 'int'.
 *
 * Revision 1.5  2002/02/14 05:40:42  jrush
 * Cleaned up source:
 *
 * 1. ran thru the indent tool to achieve a standard look,
 * 2. added structured comments at top for use with DOxygen reporting
 *    as well as CVS keywords,
 * 3. added #ifndef/#defines to prevent duplicate inclusions,
 * 4. insured all struct/union defs have names,
 * 5. centralized prototypes in protos.h, removing incomplete ones,
 * 6. cleaned up use of bool/BOOLEAN type to suit C++ type,
 * 7. fixed initializer nesting in tumbler constants.
