-- Creates a VPC endpoint for a specified AWS service. An endpoint enables
-- you to create a private connection between your VPC and another AWS
-- service in your account. You can specify an endpoint policy to attach to
-- the endpoint that will control access to the service from your VPC. You
-- can also specify the VPC route tables that use the endpoint.
--
-- Currently, only endpoints to Amazon S3 are supported.
