| 31 ;; This file is dumped with XEmacs. | |
| 32 | |
| 33 ;; This file provides low level facilities for XEmacs startup -- | |
| 34 ;; particularly regarding the package setup. This code has to run in | |
| 35 ;; what we call "bare temacs" -- i.e. XEmacs without the usual Lisp | |
| 36 ;; environment. Pay special attention: | |
| 37 | |
| 38 ;; - not to use the `lambda' macro. Use #'(lambda ...) instead. | |
| 39 ;; (this goes for any package loaded before `subr.el'.) | |
| 40 ;; | |
| 41 ;; - not to use macros, because they are not yet available (and this | |
| 442 | 42 ;; file must be loadable uncompiled.) Built in macros, such as |
| 43 ;; `when' and `unless' are fine, of course. | |
| 428 | 44 ;; |
| 45 ;; - not to use `defcustom'. If you must add user-customizable | |
| 46 ;; variables here, use `defvar', and add the variable to | |
| 47 ;; `cus-start.el'. | |
| 48 | |
| 49 ;; Because of all this, make sure that the stuff you put here really | |
| 50 ;; belongs here. | |
| 51 | |
| 52 ;; This file requires find-paths.el. | |

| 63 ;;; Terminology: | |
| 64 | |
| 65 ;;; A *package hierarchy* is a directory that contains a collection of | |
| 66 ;;; packages; it has lisp/, info/, etc/ etc. subdirectories that | |
| 67 ;;; contain the files constituting the packages. | |
| 68 | |
| 69 ;;; A *package directory* contains package hierarchies---the package | |
| 70 ;;; hierarchies are typically in directories "xemacs-packages", | |
| 71 ;;; "mule-packages", and so on. A package hierarchy might only be | |
| 72 ;;; applicable for specific variants of XEmacs. | |
| 73 | |
| 74 ;;; Package hierarchies come in "early", "late", and "last" variants, | |
| 75 ;;; depending on their relative location in the various paths. | |
| 76 ;;; "Early" hierarchies are typically in the user's home directory, | |
| 77 ;;; "late" hierarchies are typically part of the XEmacs installation, | |
| 78 ;;; and "last" package hierarchies are for special purposes, such as | |
| 79 ;;; making the packages of some previous XEmacs version available. | |
