/* Modification History:
 * $Log: get1fe.cxx,v $
 * Revision 1.15  2004/09/11 15:02:00  jrush
 * Fixed Doxygen tags on all Session parameter arguments.
 *
 * Revision 1.14  2004/09/11 13:59:21  jrush
 * Changed all fprintf's to stderr to use the Nana library L() macro.  Also
 * removed a 2-3 minor compiler warnings.
 *
 * Revision 1.13  2004/09/04 16:02:18  jrush
 * Added Doxygen headers before each and every function definition.
 *
 * Revision 1.12  2002/05/28 03:58:42  jrush
 * Sources modified to comply with GPL licensing.
 *
 * Revision 1.11  2002/04/16 22:39:50  jrush
 * Converted many #defines into enumeration types instead, and adjusted
 * function prototypes accordingly.
 *
 * Revision 1.10  2002/04/12 11:48:50  jrush
 * Major reorganization of includes into a single base-include style.
 *
 * 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 19:51:30  jrush
 * Renamed TRUE/FALSE constant use to the C++ standard of true/false.
 *
 * Revision 1.6  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 1.5  2002/04/06 15:01:45  jrush
 * Changed INT to just 'int'.
 *
 * Revision 1.4  2002/02/14 10:08:25  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. centralized prototypes in protos.h, removing incomplete ones,
 * 4. cleaned up use of bool/BOOLEAN type to suit C++ type,
 * 5. fixed initializer nesting in tumbler constants,
 * 6. converted select() int bits into ANSI fd_set type,
 * 7. added Makefile.am for use by automake.
