Overview
--------

Thanks to the keyword template, and  almost by accident, C++ is a very
special language where one can not only specify what a program will do
once compiled, but  in addition one can specify  how the compiler will
compile  a program. This  feature gave  birth to  powerful programming
techniques,  commonly referred to  as ``metaprogramming''.  Because of
its  committment in  the Olena  and Vaucanson  projects, the  LRDE has
developped    expertize   in   metaprogramming.    Unfortunately   the
implementation is tricky and very error-prone.

Starting  from   the  simple  idea  that   ``we  want  metaprogramming
efficiency, but we don't want  to write it'', the Transformers project
was  initiated.   It  aims  at  converting  naive   (but  decent)  C++
programming into  high-speed (but indecent)  C++ source code.  To this
end,  several  tasks must  be  addressed:  basically the  Transformers
project aims at designing a set of tools to manipulate C++ programs.

The  software  we   use  to  build  those  tools   comes  mainly  from
Stratego/XT.

Its main goal  is to ease the use of  static C++ programming patterns,
such as the  ones which are currently in use in  Olena or Vaucanson by
letting  the programmer use  classical (human  readable) C++  code and
transform it into efficient generic code.

There are several steps to go before we have a usable tool.
