ocaml-smithy is an AWS SDK for OCaml that is code-generated from Smithy models representing AWS services, with the models sourced from the smithy-rs project. The project is built in OCaml using the Dune build system, though signing and performing operations are not yet implemented, and some protocols still require additional work. Development involves code generation via a Smithy executable, automated testing, and documentation building through standard Dune commands.
