[xemacs-hg @ 2004-11-02 09:51:04 by ben] To: xemacs-patches@xemacs.org internals/index.texi: Deleted. Incorporated into internals.texi. Having a separate index file messes up texinfo-master-menu. internals/internals.texi: Add bunches and bunches and bunches and bunches of stuff, taken from documentation floating around in various places -- text.c, file-coding.c, other .c and .h files, stuff that I wrote up for an old XEmacs contract, proposals written up in the process of an e-mail discussion, etc. Fix up some mistakes, esp. in CCL. Extra crap from CCL, duplicated with Lispref, removed. Sections on Old Future Work and Future Work Discussion added. Bunches of other work. Add bunches of documentation taken from the source code. Fixup various places to use @strong{}, @code{}, @file{}. Create new Text chapter, split off from Buffers and Textual Representation. Create new chapter for MS Windows, mostly written from scratch. Consolidate all Mule info under "Multilingual Support". Break up chapter on modules and move some parts to the sections discussing the modules, for consolidation purposes. Add a big cross-reference table for all the modules to where they're discussed (or not). New chapter Asynchronous Events; Quit Checking. (Taken from various parts of the code.) New Introduction. New section on Focus Handling (from the code). NOTE that in the process, I discovered that we essentially have FOUR redundant introductions to Mule issues! Someone really needs to go through and clean them up and integrate them (sjt?).
