Break-rewrite is just a call of the standard ACL2 read-eval-print
ld, on a ``wormhole'' state. Thus, you may execute most
commands you might normally execute at the top-level of ACL2.
However, all state changes you cause from within break-rewrite are
lost when you exit or
:eval the rule. You cannot modify stobjs from
within the break. See break-rewrite for
more details and see ld for general information about the
standard ACL2 read-eval-print loop.
