-- Creates a listing for Amazon EC2 Reserved Instances to be sold in the
-- Reserved Instance Marketplace. You can submit one Reserved Instance
-- listing at a time. To get a list of your Reserved Instances, you can use
-- the DescribeReservedInstances operation.
--
-- The Reserved Instance Marketplace matches sellers who want to resell
-- Reserved Instance capacity that they no longer need with buyers who want
-- to purchase additional capacity. Reserved Instances bought and sold
-- through the Reserved Instance Marketplace work like any other Reserved
-- Instances.
--
-- To sell your Reserved Instances, you must first register as a seller in
-- the Reserved Instance Marketplace. After completing the registration
-- process, you can create a Reserved Instance Marketplace listing of some
-- or all of your Reserved Instances, and specify the upfront price to
-- receive for them. Your Reserved Instance listings then become available
-- for purchase. To view the details of your Reserved Instance listing, you
-- can use the DescribeReservedInstancesListings operation.
