52 : : // std::clog. This is used to initialize str to a local stringstream into
53 : : // which all verbose output goes by default, i.e., it will not be shown.
54 : : // This solution is chosen instead of trickery with null-streams, as
55 : : // boost:formatted output into null-streams caused invalid reads in

58 : : // std::clog, is only used to detect whether client code passed a default
