746: #
747: # Because of this, exclusion of items in lonnet.perm.log for nodes which are
748: # no longer part of the cluster from adding to the overall "unsend" count

753: # is a memory location, and $cmd is the command sent to the remote node.
754: #
755: # Starting with 2.2.0 (released 8/21/2006) logging for "S" (completion) events
756: # had sethost:$host_id:$cmd after LondTransaction=HASH(hexadecimal)->getClient()

761: #
762: # The net effect of these changes is that lonnet.perm.log is now accessed three
763: # times: (a) oldest record is checked, if earlier than release date for 2.5.0
