5 | ;;; Singular interactive mode. |

9 | ;;; |
---|
10 | ;;; How you use this file very much depends on your attitude |
---|
11 | ;;; towards Emacs: |
---|
12 | ;;; |
---|
13 | ;;; 1) If you are going to use Emacs solely as frontend to |
---|
14 | ;;; Singular you do not have to worry at all about this file. |
---|
15 | ;;; 2) If you are already an experienced Emacs user you may |
---|
16 | ;;; want to copy this file's contents to your .emacs file. |
---|
17 | ;;; 3) If you are planning to become an experienced Emacs user |
---|
18 | ;;; you may use this file as starting point for your .emacs |
---|
19 | ;;; file, that is, for your Emacs initialization file. Simply |
---|
20 | ;;; copy it to your home directory and rename it to ".emacs" |
---|
21 | ;;; (without the quotes, of course). Then edit it as |
---|
22 | ;;; described below. |
---|
23 | ;;; |
---|
24 | ;;; In cases 2) and 3) you should be careful what exactly to copy |
---|
25 | ;;; to your .emacs file. In general, you need the following: |
---|
26 | ;;; |
---|
27 | ;;; o the hook-customizations with `add-hook'; |
---|
28 | ;;; o the pre-customized settings with `custom-set-variables' and |
---|
29 | ;;; `custom-set-faces'; |
---|
30 | ;;; o the code which creates menus for starting Singular; |
---|
31 | ;;; o the code which loads singular.el (located at the end of |
---|
32 | ;;; this file) you have to replace by something else, for |
---|
33 | ;;; example, an `autoload'. |
---|
34 | ;;; o the code which is in .emacs-general |
---|
35 | ;;; |
---|
36 | ;;; Here is how the Singular customization in your .emacs may |
---|
37 | ;;; look like: |
---|
38 | ;;; |
---|
39 | ;;; ;; extra key bindings |
