29 ;; This package provides Emacs support for Octave. |
|
|
30 ;; It defines Octave mode, a major mode for editing |
|
|
31 ;; Octave code. |
|
|
32 |
|
|
33 ;; The file octave-hlp.el provides `octave-help', a facility for looking up |
|
|
34 ;; documentation on a symbol in the Octave info files. |
|
|
35 |
|
|
36 ;; The file octave-inf.el contains code for interacting with an inferior |
|
|
37 ;; Octave process using comint. |
|
|
38 |
|
|
39 ;; See the documentation of `octave-mode', `octave-help' and |
|
|
40 ;; `run-octave' for further information on usage and customization. |

492 |
|
|
493 To begin using this mode for all `.m' files that you edit, add the |

500 To automatically turn on the abbrev, auto-fill and font-lock features, |
|
|
501 add the following lines to your `.emacs' file as well: |
|
|
502 |
|
|
503 (add-hook 'octave-mode-hook |
