(* This module provides the official functions to declare new variables, 
   parameters, constants and inductive types. Using the following functions
   will add the entries in the global environment (module [Global]), will
   register the declarations in the library (module [Lib]) --- so that the
   reset works properly --- and will fill some global tables as [Nametab] and
   [Impargs]. *)

(*s It also provides a function [global_reference] to construct a global
  constr (a constant, an inductive or a constructor) from an identifier.
  To do so, it first looks for the section path using [Nametab.sp_of_id] and
  then constructs the corresponding term, associated to the current 
  environment of variables. *)
