;;; test-system-commands-resolve-and-run.el --- Tests for system-commands helpers + wrappers -*- lexical-binding: t; -*-
;;; Commentary:
;; Sibling `test-system-commands-keymap.el' locks the keymap shape.
;; This file covers the runtime helpers and commands:
;;
;; cj/system-cmd--resolve
;; cj/system-cmd
;; cj/system-cmd-exit-emacs
;; cj/system-cmd-restart-emacs
;; cj/system-command-menu
;;
;; Process and prompt primitives are stubbed.
;;; Code:

(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
