/* -----------------------------------------------------------------------------
 * std_except.i
 *
 * SWIG library file with typemaps to handle and throw STD exceptions in a
 * language and STL independent way, i.e., the target language doesn't
 * require to support STL but only the 'exception.i' mechanism.
 *
 * These typemaps are used when methods are declared with an STD
 * exception specification, such as
 *
 *   size_t at() const throw (std::out_of_range);
 *
 * The typemaps here are based on the language independent
 * 'exception.i' library. If that is working in your target language,
 * this file will work.
 * 
 * If the target language doesn't implement a robust 'exception.i'
 * mechanism, or you prefer other ways to map the STD exceptions, write
 * a new std_except.i file in the target library directory.
