;;; tools/upload/config.el

;; Uses `ssh-deploy'. Expects a .dir-locals.el file in your project and expects
;; `ssh-deploy-root-remote' to be defined there to tell Emacs where to upload
;; files to. Supports FTP and SSH. If unset, automatically ascertains
;; `ssh-deploy-root-local' using `doom-project-root'.
;;
;; Interactive versions of `ssh-deploy's functions are in autoload.el.
