   1.113 +;; To install, just copy this file into a directory on your load-path
   1.114 +;; (and byte-compile it). To set up Emacs to automatically edit files
   1.115 +;; ending in ".lua" or with a lua hash-bang line using lua-mode add
   1.116 +;; the following to your init file:
   1.117 +;;
   1.118 +;; (autoload 'lua-mode "lua-mode" "Lua editing mode." t)
   1.119 +;; (add-to-list 'auto-mode-alist '("\\.lua$" . lua-mode))

   1.125 -      
   1.126 +;; Lua-mode supports c-mode style formatting and sending of
   1.127 +;; lines/regions/files to a Lua interpreter. An interpreter (see
   1.128 +;; variable `lua-default-application') will be started if you try to
   1.129 +;; send some code and none is running. You can use the process-buffer
   1.130 +;; (named after the application you chose) as if it were an
   1.131 +;; interactive shell. See the documentation for `comint.el' for
   1.132 +;; details.
   1.133  
   1.134 +;; Lua-mode works with Hide Show minor mode (see ``hs-minor-mode``).
