• namespace -Wrap the generated classes with the specified namespace.
• header - Will be inserted right after ANTLRs own imports at the top of the generated file. 
• includes, pre-includes, post-includes - same meaning as in C Target
• init - Will be inserted at the end of the constructor of the lexer/parser. Here you can setup your own instance attributes.
• members - Will be inserted in the class body of the lexer/parser. This is the right place for custom methods and class attributes.

• -debug option: mostly useful for integration into ANTLRWorks.
• output=template: StringTemplate has not been ported to C++, so template-based recognizers are not supported.
• TreeParser(output = AST): useful for generating trees
