25 ;; Major mode for editing Dos scripts (batch files). Provides syntax
26 ;; highlighting, a basic template, access to Dos help pages, imenu/outline
27 ;; navigation, and the ability to run scripts from within Emacs. The syntax
28 ;; groups for highlighting are:
31 ;; dos-label-face :LABEL
32 ;; font-lock-comment-face rem
33 ;; font-lock-builtin-face copy
34 ;; font-lock-keyword-face goto
35 ;; font-lock-warning-face cp
36 ;; font-lock-constant-face [call] prog
37 ;; font-lock-variable-name-face %var%
38 ;; font-lock-type-face -option
42 ;; See documentation of function `dos-mode'.
44 ;; Separate package `dos-indent' (Matthew Fidler) provides rudimentary
45 ;; indentation, see http://www.emacswiki.org/emacs/dos-indent.el.
49 ;; Inspired by `batch-mode' (Agnar Renolen) and `cmd-mode' (Tadamegu Furukawa).
