    Some RapidJSON features are configurable to adapt the library to a wide

    variety of platforms, environments and usage scenarios.  Most of the

    features can be configured in terms of overriden or predefined

    preprocessor macros at compile-time.

    Some additional customization is available in the \ref CEREAL_RAPIDJSON_ERRORS APIs.

    \note These macros should be given on the compiler command-line

          (where applicable)  to avoid inconsistent values when compiling

          different translation units of a single application.
