let inpath =
  match Sys.argv with
  | [| _; inpath |] -> inpath
  | _ -> usage ()
  
let () =
  match Filename.extension inpath with
  | ".byte" ->
    let bytefile = Bytefile.read inpath in (* Load the given bytecode file *)
    Bytefile.print stdout bytefile;        (* Pretty-print its contents    *)
    Interp.eval_bytefile bytefile;         (* Evaluate its code            *)
  | ".cmo" ->
    let cmofile = Cmofile.read inpath in   (* Load the given .cmo file     *)
