Hello,

You can add options with the Command_options.add function.
Exemple:

let my_options = [
  "-nl", Arg.Unit print_newline, "just print a newline" ;
  (* other options ... *)  
]
in
List.iter (fun (o,spec,s) -> Command_options.add o spec s) my_options;

They will be handled when ocamlp3l analyzes the command line.
