[xemacs-hg @ 2004-12-27 12:25:14 by michaels] 2004-12-18 Mike Sperber <mike@xemacs.org> * package-admin.el: * startup.el: Reflect the changes made in packages.el. * packages.el: * loadup.el: * make-docfile.el: * package-admin.el: * startup.el: * update-elc.el (early-package-hierarchies) (late-package-hierarchies) (last-package-hierarchies): Renamed these from `early-packages', `late-packages' and `last-packages'. * packages.el: Rewrote package-finding logic to separate the concepts of "package directories" and "package hierarchies". Added explanation of these concepts. * setup-paths.el: * find-paths.el: Added parameter descriptions to some of the docstrings. * packages.el, setup-paths.el: Make terminology more explicit about "package hierarchies" * startup.el (emacs-roots, emacs-data-roots) (user-init-directory-base, user-init-directory) (user-init-file-base, user-init-file-base-list) (user-home-init-file-base-list) (load-home-init-file, load-user-init-file-p) (startup-find-load-path, startup-setup-paths) (startup-find-load-path-for-packages): Moved these back from setup-paths.el where they belong---setup-paths.el now again, as documented, contains no code that sets global variables. (They were moved from startup.el to setup-paths.el on 2003-02-28.) Clarify that in the comment at the top. * setup-paths.el (paths-find-emacs-roots): Restored `invocation-directory' 'invocation-name' parameters removed on 2003-02-28; they're useful for debugging.
