+   //  The intent is to propose the following for addition to namespace std
+   //  in the C++ Standard Library, and to then deprecate EXIT_SUCCESS and
+   //  EXIT_FAILURE.  As an implementation detail, this header defines the
+   //  new constants in terms of EXIT_SUCCESS and EXIT_FAILURE.  In a new
+   //  standard, the constants would be implementation-defined, although it
+   //  might be worthwhile to "suggest" (which a standard is allowed to do)
+   //  values of 0 and 1 respectively.
+
+   //  Rationale for having multiple failure values: some environments may
+   //  wish to distinguish between different classes of errors.
+   //  Rationale for choice of values: programs often use values < 100 for
+   //  their own error reporting.  Values > 255 are sometimes reserved for
+   //  system detected errors.  200/201 were suggested to minimize conflict.
