It is almost my syntax! I use just:
   (* camlp4o -I some_dir some_quots.cmo some_more_quots.cmo *)

Therefore my shell script tests "(* camlp4o" in my source file with a simple
grep. With some appropriate "sed", I build the right command lines. And I
have also a "depend" entry which tests the .cmo files of this line to
create the dependencies.

Yes. If you need other preprocessors, you can do that. You can take the
version in camlp4 (tools/camlp4_comm.sh) or take the ideas in it, if you
want, no problem. It is implementable, since all compilation of camlp4
files use that (including the files not to be preprocessed).
