  numbering.
end note
autonumber
act1 -[#FF0000]> Front
act1 -[#FF0000]-> Front
autonumber stop
autonumber 100
Front -[#0000FF]> Middle
Front -[#0000FF]-> Middle
autonumber stop
== Regular execution ==
hnote over Back: idle
Back --> CSV
ref over Back
  This CSV format.
end ref
... 2 minutes latter ...
CSV --> Back
== Logic ==
Middle -> Back: Request.
alt successful case
	Back -> Middle: Accepted.
else some kind of failure
	Back -> Middle: Failure.
	group My own label
		Middle -> Log : Log start
	    loop 1000 times
