|

31
|
|
|
32 ;; This file provides low level facilities for XEmacs startup --
|
|
|
33 ;; particularly regarding the package setup. This code has to run in
|
|
|
34 ;; what we call "bare temacs" -- i.e. XEmacs without the usual Lisp
|
|
|
35 ;; environment. Pay special attention:
|
|
|
36
|
|
|
37 ;; - not to use the `lambda' macro. Use #'(lambda ...) instead.
|
|
|
38 ;; (this goes for any package loaded before `subr.el'.)
|
|
|
39 ;;
|
|
|
40 ;; - not to use macros, because they are not yet available (and this
|
|
442
|
41 ;; file must be loadable uncompiled.) Built in macros, such as
|
|
|
42 ;; `when' and `unless' are fine, of course.
|
|
428
|
43 ;;
|
|
|
44 ;; - not to use `defcustom'. If you must add user-customizable
|
|
|
45 ;; variables here, use `defvar', and add the variable to
|
|
|
46 ;; `cus-start.el'.
|
|
|
47
|
|
|
48 ;; Because of all this, make sure that the stuff you put here really
|
|
|
49 ;; belongs here.
