+// $Log$
+// Revision 1.10 1998/11/07 19:07:03 curt
+// Enable release builds using the --without-logging option to the configure
+// script. Also a couple log message cleanups, plus some C to C++ comment
+// conversion.
+//
+// Revision 1.9 1998/11/06 21:17:26 curt
+// Converted to new logstream debugging facility. This allows release
+// builds with no messages at all (and no performance impact) by using
+// the -DFG_NDEBUG flag.
