IDL compiler front-end library

This is a part of the Nirvana project.

Purpose

This library is intended for the easy creation of the CORBA IDL compilers.

It performs:

• Command line parsing
• Preprocessing
• Parsing IDL files
• Building the Abstract Syntax Tree

To create an IDL compiler:

• Derive your compiler class from class IDL_FrontEnd.
• Derive your back-end code generator from class AST::CodeGen.
• Override pure virtual method IDL_FrontEnd::generate_code(AST::Root& tree).

For the example see: https://github.com/nirvanaos/idlfe/tree/master/example
