# TEST	repmgr007
# TEST	Basic repmgr client shutdown/restart test.
# TEST
# TEST	Start an appointed master site and two clients. Shut down and
# TEST	restart each client, processing transactions after each restart.
# TEST	Verify all expected transactions are replicated.
# TEST
# TEST	Run for btree only because access method shouldn't matter.
