-- You can no longer purchase Scheduled Instances.
--
-- Purchases the Scheduled Instances with the specified schedule.
--
-- Scheduled Instances enable you to purchase Amazon EC2 compute capacity
-- by the hour for a one-year term. Before you can purchase a Scheduled
-- Instance, you must call DescribeScheduledInstanceAvailability to check
-- for available schedules and obtain a purchase token. After you purchase
-- a Scheduled Instance, you must call RunScheduledInstances during each
-- scheduled time period.
--
-- After you purchase a Scheduled Instance, you can\'t cancel, modify, or
-- resell your purchase.
