| 29 ;; This file is dumped with XEmacs. | |
| 30 | |
| 31 ;; This file provides low level facilities for XEmacs startup -- | |
| 32 ;; particularly regarding the package setup. This code has to run in | |
| 33 ;; what we call "bare temacs" -- i.e. XEmacs without the usual Lisp | |
| 34 ;; environment. Pay special attention: | |
| 35 | |
| 36 ;; - not to use the `lambda' macro. Use #'(lambda ...) instead. | |
| 37 ;; (this goes for any package loaded before `subr.el'.) | |
| 38 ;; | |
| 39 ;; - not to use macros, because they are not yet available (and this | |
| 442 | 40 ;; file must be loadable uncompiled.) Built in macros, such as |
| 41 ;; `when' and `unless' are fine, of course. | |
| 428 | 42 ;; |
| 43 ;; - not to use `defcustom'. If you must add user-customizable | |
| 44 ;; variables here, use `defvar', and add the variable to | |
| 45 ;; `cus-start.el'. | |
| 46 | |
| 47 ;; Because of all this, make sure that the stuff you put here really | |
| 48 ;; belongs here. | |

| 74 ;;; "Early" hierarchies are typically in the user's home directory, | |
