Those options can be used by any program that parses command line arguments using the standard module Arg. It may modify some global parameters, and return a parameter type for other options.
val default : tDefault options
val make : t Pervasives.ref -> (string * Arg.spec * string) listProduce of list of options suitable for Arg.parse, that may modify global parameters and the given option reference. After parsing, the reference content will reflect CLI options
val global : t Pervasives.refGlobal parameters, can be used as a mutable default
val global_opts : (string * Arg.spec * string) listOptions that modify global. Caution, this might miss some options from modules that aren't registered yet.
since 0.6.1 , use mk_global_opts instead
val mk_global_opts : unit -> (string * Arg.spec * string) list
