### ACL2-PC::USE

(atomic macro) `` use a lemma instance

    Major Section:  PROOF-CHECKER-COMMANDS

    Example:
    (USE true-listp-append
         (:instance assoc-of-append (x a) (y b) (z c)))
    -- Add two top-level hypotheses, one the lemma called
       true-listp-append, and the other an instance of the lemma called
       assoc-of-append by the substitution in which x is assigned a, y
       is assigned b, and z is assigned c.

    General Form:
    (use &rest args)

Add the given lemma instances to the list of top-level hypotheses. See hints for the syntax of `:use` hints in `defthm`, which is essentially the same as the syntax here (see the example above).

This command calls the `prove` command, and hence should only be used at the top of the conclusion.
