Ppx_derivers ------------ Ppx_derivers is a tiny package whose sole purpose is to allow [ppx_deriving](https://github.com/whitequark/ppx_deriving) and [ppx_type_conv](https://github.com/janestreet/ppx_type_conv) to inter-operate gracefully when linked as part of the same [ocaml-migrate-parsetree](https://github.com/let-def/ocaml-migrate-parsetree) driver.
