Proof of proveit.logic.booleans.conjunction.true_eval theorem

import proveit
theory = proveit.Theory() # the theorem's theory

%proving true_eval

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
true_eval:
(see dependencies)

true_eval may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
