-- | 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. For more information, see Reserved Instance Marketplace in the
-- Amazon Elastic Compute Cloud User Guide.
