%proving nonpos_int_is_int_nonpos
With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of nonpos_int_is_int_nonpos: (see dependencies)
nonpos_int_is_int_nonpos may now be readily provable (assuming required theorems are usable). Simply execute "%qed".
