-Takes all the arguments of calc_recur, and calculates a prorated charge
-in one of two ways:
+Takes all the arguments of calc_recur. Calculates a prorated charge from
+the $sdate to the cutoff day for this package definition, and sets the $sdate
+and $param->{months} accordingly. base_recur() will be called to determine
+the base price per billing cycle.
-- If 'sync_bill_date' is set: Charge for a number of days to synchronize
- this package to the customer's next bill date. If this is their only
- package (or they're already synchronized), that will take them through
- one billing cycle.
-- If 'cutoff_day' is set: Prorate this package so that its next bill date
- falls on that day of the month.
+Options:
+- add_full_period: Bill for the time up to the prorate day plus one full
+billing period after that.
+- prorate_round_day: Round the current time to the nearest full day,
+instead of using the exact time.
+- prorate_defer_bill: Don't bill the prorate interval until the prorate
+day arrives.
