    BNF Converter: C++ abstract syntax generator
    Copyright (C) 2004  Author:  Michael Pellauer

    Description   : This module generates the C++ Abstract Syntax
                    tree classes. It generates both a Header file
                    and an Implementation file, and uses the Visitor
                    design pattern. It uses STL (Standard Template Library).

    Author        : Michael Pellauer
    Created       : 4 August, 2003
