Hello,

I would like to write a preprocessor of my own (to make a lisp
syntax). In the process, I am slowly catching up with the Ocaml AST.

However, I am clueless about how I should feed the compiler with my
generated AST. Should I use Marshall? should I output the same as the
option -dparsetree? Should I use some "purple magic"?

Can anybody give me a pointer about how to do this?

Thanks,
Loup Vaillant
