[xemacs-hg @ 2002-03-18 10:07:30 by ben] config.inc.samp, xemacs.mak: Deal with never-ending perl quoting problems. README: Include a long, long description of the suggested directory layout for developing XEmacs. This should probably go as part of a larger document, a "Getting Started with Developing XEmacs". #### Does such a document exist? etc\unicode\mule-ucs\*: New directory, containing translation files for the remaining charsets that are not in unicode\unicode-consortium but are in mule-ucs. etc\unicode\other\*: New directory, containing translation files made up on an ad-hoc basis. etc\unicode\README: Update. * Some ChangeLog entries from stuff that got applied long ago never got checked in, due to the nasty SCCS "oops, i forgot again ..." bug. mule\lao.el: Convert stuff to XEmacs-style. mule\thai-xtis.el: Move thai-xtis-chars.el stuff to here, since we can now handle encountering characters of a charset before the charset is defined. mule\thai-xtis-chars.el: Removed, moved into thai-xtis.el. mule\mule-msw-init.el: Move some stuff into mule-msw-init-late.el, which references charsets and thus needs to be delayed until after all charsets have been created. mule\mule-msw-init-late.el: New file, some stuff from mule-msw-init.el. dumped-lisp.el: Load the remaining languages -- lao, indian, devanagari, tibetan. Load new file mule-msw-init-late. unicode.el: Load the new tables for Ethiopic, Vietnamese, and other languages extracted from mule-ucs. mule\lao.el: Convert stuff to XEmacs-style. mule\thai-xtis.el: Move thai-xtis-chars.el stuff to here, since we can now handle encountering characters of a charset before the charset is defined. mule\thai-xtis-chars.el: Removed, moved into thai-xtis.el. mule\mule-msw-init.el: Move some stuff into mule-msw-init-late.el, which references charsets and thus needs to be delayed until after all charsets have been created. mule\mule-msw-init-late.el: New file, some stuff from mule-msw-init.el. mule\lao.el: Convert stuff to XEmacs-style. mule\thai-xtis.el: Move thai-xtis-chars.el stuff to here, since we can now handle encountering characters of a charset before the charset is defined. mule\thai-xtis-chars.el: Removed, moved into thai-xtis.el. mule\mule-msw-init.el: Move some stuff into mule-msw-init-late.el, which references charsets and thus needs to be delayed until after all charsets have been created. mule\mule-msw-init-late.el: New file, some stuff from mule-msw-init.el. dumped-lisp.el: Load the remaining languages -- lao, indian, devanagari, tibetan. Load new file mule-msw-init-late. unicode.el: Load the new tables for Ethiopic, Vietnamese, and other languages extracted from mule-ucs. mule\lao.el: Convert stuff to XEmacs-style. mule\thai-xtis.el: Move thai-xtis-chars.el stuff to here, since we can now handle encountering characters of a charset before the charset is defined. mule\thai-xtis-chars.el: Removed, moved into thai-xtis.el. mule\mule-msw-init.el: Move some stuff into mule-msw-init-late.el, which references charsets and thus needs to be delayed until after all charsets have been created. mule\mule-msw-init-late.el: New file, some stuff from mule-msw-init.el. fns.c, lread.c: Add variable require-prints-loading-message to cause loading messages to get printed when a file is loading during a `require', which normally doesn't happen. This can be set using env var XEMACSDEBUG to debug problems with non-interactive compilation. Modify load-internal so it prints "Requiring: ..." instead of "Loading: ..." when appropriate.
