+      This class provides a syntax similar to output-streams for convenience.
+      For compability with other libraries it is inheriting the class
+      \c std::exception.
+    
+      Here is an example how to use an instance of this class in C++:

+      
+      Mind that the macro uses a variable with the name \c _e. Make sure, that
+      you don't use this variable-name in any of the macro-arguments!
+
+      Ruby already comes with exception classes:
+      \include exceptiontest/exceptiontest.rb
