25 Notes:  This command is used by biller.ec.  Projects are billed for the
26 usage recorded in the administrative copies of the PDTs.  (These copies
27 are created by the crank, called by master.ec, from the system copies
28 of the PDTs.)  Meanwhile, logged in users are accruing additional usage
29 charges, recorded in the system copies of the PDTs.  Execution of this
30 command subtracts the charges that have just been billed, leaving in
31 the system PDTs only the most recently accrued charges that have not
32 yet been billed.

34 If the system crashes while this command is running, the command can be
35 restarted from the beginning.
