Metagene: a C++ meta-program generation tool

The C++ language offers a two layer evaluation model. Thus, it is possible to evaluate a program in two steps: the so-called static and dynamic evaluations. Static evaluation is used for reducing the amount of work done at execution-time. Programs executed statically (called metaprograms) are written in C++ through an intensive use of template classes. Due to the complexity of these structures, writing, debugging and maintaining C++ meta-programs is a difficult task. Metagene is a program transformation tool which simplifies the development of such programs. Due to the similarities between C++ meta-programming and functional programming, the input language of Metagene is an ML language. Given a functional input program, Metagene outputs the corresponding C++ meta-program expressed using template classes.
