/* Modification History:
 * $Log: rcfile.cxx,v $
 * Revision 1.8  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 1.7  2004/09/04 16:02:18  jrush
 * Added Doxygen headers before each and every function definition.
 *
 * Revision 1.6  2002/05/28 03:58:42  jrush
 * Sources modified to comply with GPL licensing.
 *
 * Revision 1.5  2002/04/12 11:48:51  jrush
 * Major reorganization of includes into a single base-include style.
 *
 * Revision 1.4  2002/04/12 10:43:50  jrush
 * Moved libsrc/rcfile.cxx to server/rcfile.cxx
 *
 * Revision 1.4  2002/04/06 15:01:17  jrush
 * Changed INT to just 'int'.
 *
 * Revision 1.3  2002/02/17 10:10:45  jrush
 * Commented out unused Udanax-configuration file directives, to avoid confusion.
 *
 * Revision 1.2  2002/02/14 09:27:43  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. fixed compiler warnings re ambiguous assign/compares,
 *    needed casts and unused/uninitialized variables,
 * 4. fixed funcs that didn't specify a return type,
 * 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,
 * 8. renamed vars that conflict with C++ keywords (new, this),
 * 9. fixed global/extern confusion re some global vars.
