-- | 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 <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-market-general.html Reserved Instance Marketplace> in the /AmazonElastic Compute Cloud User Guide/.
