# TEST	rep054
# TEST	Test of internal initialization where a far-behind
# TEST	client takes over as master.
# TEST	One master, two clients.
# TEST	Run rep_test and process.
# TEST	Close client 1.
# TEST	Run rep_test, opening new databases, and processing
# TEST	messages.  Archive as we go so that log files get removed.
# TEST	Close master and reopen client 1 as master.  Process messages.
# TEST	Verify that new master and client are in sync.
# TEST	Run rep_test again, adding data to one of the new
# TEST	named databases.
