# rep065script - procs to use at each replication site in the
# replication upgrade test.
#
# type: START, PROCMSGS, VERIFY
# 	START starts up a replication site and performs an operation.
#		the operations are:
#		REPTEST runs the rep_test_upg procedure on the master.
#		REPTEST_GET run a read-only test on a client.
#		REPTEST_ELECT runs an election on the site.
# 	PROCMSGS processes messages until none are left.
#	VERIFY dumps the log and database contents.
# role: master or client
# op: operation to perform
# envid: environment id number for use in replsend
# allids: all env ids we need for sending
# ctldir: controlling directory
# mydir: directory where this participant runs
# reputils_path: location of reputils.tcl
