Proof of proveit.logic.booleans.implication.false_implies_false theorem

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

%proving false_implies_false

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

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

%qed

proveit.logic.booleans.implication.false_implies_false has been proven.
