+/* -----------------------------------------------------------------------------
+ * 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.
