/// The whole purpose of this extremely-simple function is to delegate execution
/// to an internal module that does not contain a proper ::main() function.
/// This is to allow unit-testing of the internal code.
///
/// \param argc The number of arguments passed on the command line.
/// \param argv NULL-terminated array containing the command line arguments.
///
/// \return 0 on success, some other integer on error.
///
/// \throw std::exception This throws any uncaught exception.  Such exceptions
///     are bugs, but we let them propagate so that the runtime will abort and
///     dump core.
