We chose to use standard tools, that have a good diffusion and that have been used for real applications, in order to increase the diffusion of our program, its growth, its understanding. We chose the ObjectCaml v2.02 programming language, developed at INRIA (France), with the tools, offered with it, for syntactical and lexical analysis, ocamlyacc and ocamllex (that are similar to the more famous GNU yacc and lex). This allowed quick development and high compatibility.
We love to say that all the used tools are available, freely, at the web site www.inria.fr.
