open Coqdep_common

(** [coqdep_boot] is a stripped-down version of [coqdep], whose
    behavior is the one of [coqdep -boot]. Its only dependencies
    are [Coqdep_lexer], [Coqdep_common] and [Unix], and it should stay so.
    If it needs someday some additional information, pass it via
    options (see for instance [option_natdynlk] below).
