Launch CamlP4 with some help of OCamlFind

I do not know why but there is no ocamlfind camlp4o. Here is a tip for this:


# \ mark is actually a backslash.

camlp4o \
    `ocamlfind query -r -i-format $*` \
    `ocamlfind query -r -a-format -predicates syntax,preprocessor $*`

I named this script as ocamlfind-camlp4o. With this, you can launch P4 with your packages like ocamlfind-camlp4o pa_ovisitor orakuda.syntax.
