(* 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]. *)
