(** Command Line options *)

(* HOWTO define a new command line and config file option.

   1. Add an entry in the following let...and...and... binding.  See the documentation in
      [CommandLineOption.mli], and use the existing options as a guide.  Preferably the identifer
      and long option name are the same modulo underscores versus hyphens.

      E.g. [and new_option = CLOpt.mk_bool ~long:"new-option"]

   2. Add a line to the [Freeze initialized configuration values] section below.

      E.g. [and new_option = !new_option]

   3. Add a line to [config.mli].

      E.g. [val new_option : bool]

   These are all in alphabetical order as much as possible.

   The references representing the command line options are defined in a single
   simultaneous let...and...and... binding in order to allow the type-checker to catch
   uses of one reference in code for another. This avoids being sensitive to
   initialization-order and unintended dependence on the order in which options appear on
   the command line. For cases where order-dependence is desired, the interacting options
   can be defined together sharing a reference. See debug and specs_library below for two
   different examples. *)
