(* 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 such as 
   [Nametab] and [Impargs]. *)
