-- Describes your account\'s Reserved Instance listings in the Reserved
-- Instance Marketplace.
--
-- 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.
--
-- As a seller, you choose to list some or all of your Reserved Instances,
-- and you specify the upfront price to receive for them. Your Reserved
-- Instances are then listed in the Reserved Instance Marketplace and are
-- available for purchase.
--
-- As a buyer, you specify the configuration of the Reserved Instance to
-- purchase, and the Marketplace matches what you\'re searching for with
-- what\'s available. The Marketplace first sells the lowest priced
-- Reserved Instances to you, and continues to sell available Reserved
-- Instance listings to you until your demand is met. You are charged based
-- on the total price of all of the listings that you purchase.
--
-- For more information, see
-- <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-market-general.html Reserved Instance Marketplace>
-- in the /Amazon EC2 User Guide/.
