Yeah, you are right, i was just showing you the final step... Ie what
the user will have to write to compile...

I don't want to specify a full language schemes... Too much complicated.
I just want to make it in ocaml in order to ease ocaml user to write
ocaml script to compile ocaml ( i repeat a lot of time ocaml because i
still think that it is enough expressive to describe a makefile process
and i don't want people to learn 10 language to create : a configure.in,
a Makefile.am... ).

Maybe i miss one step : where can i found interscript ( i am not an
expert, i am sorry ).
