Proof of proveit.logic.booleans.true_not_false theorem

import proveit
from proveit.logic.booleans  import false_not_true
theory = proveit.Theory() # the theorem's theory

%proving true_not_false

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

true_not_false has been proven.  Now simply execute "%qed".
