# TEST	rep062
# TEST	Test of internal initialization where client has a different
# TEST  kind of database than the master.
# TEST
# TEST	Create a master of one type, and let the client catch up.
# TEST	Close the client.
# TEST	Remove the database on the master, and create a new
# TEST	database of the same name but a different type.
# TEST	Run the master ahead far enough that internal initialization
# TEST	will be required on the reopen of the client.
# TEST	Reopen the client and verify.
