-Q7.2.2: XEmacs segfaults when I use very big numbers!
------------------------------------------------------
-
-GMP by default allocates temporaries on the stack. If you run out of
-stack space, you're dead; there is no way that we know of to reliably
-detect this condition, because `alloca' is typically implemented to be
-_fast_ rather than robust. If you just need a little more oomph, use a
-bigger stack (_e.g._, the `ulimit -s' command in bash(1)). If you want
-robustness at the cost of speed, configure GMP with `--disable-alloca'
-and rebuild the GMP library.
-
- We do not know whether BSD MP uses `alloca' or not. Please send any
-information you have as a bug report (`M-x report-xemacs-bug <RET>'),
-which will give us platform information. (We do know that BSD MP
-implementations vary across vendors, but how much, we do not know yet.)

-Q7.2.3: Bignums are really slow!
---------------------------------
-
-Many Linux distributions compile all their packages for the i386, and
-this is costly. An optimized version can give you two or three orders
-of magnitude better performance for a Pentium III or IV. (Yes, really.
-See `http://www.swox.com/gmp/gmp-speed.html'.)

-Q7.2.4: Equal bignums don't compare as equal! What gives?
-----------------------------------------------------------
-
-Ah, Grasshopper, I see you are using `(eq x y)'. The Bodhisattva CLTL2
-warned of the illusion that equal numbers would be `eq'! Meditate on
-the deeper truths of `eql', in which numbers of the same type which
-have equal values compare equal, and `=', which does any necessary type
-coercions before comparing for equality.
-
- Yeah, yeah, it has always worked for integer types, because fixnums
-and characters have an immediate representation. Sorry about that;
-arbitrary precision obviously requires consing new objects because the
-objects are "large" and of variable size, and the definition of `eq'
-does not permit different objects to compare as equal.

-
-Q8.0.2: What is AUCTeX? Where do you get it?
----------------------------------------------
-
-AUCTeX is a complex and sophisticated editing package dedicated to TeX
-and related text formatting languages, including LaTeX and Texinfo. It
-provides support for running TeX on a file or part of a file, include
-files, and of course shortcuts for entering common TeX macros, LaTeX
-environments, etc, and for fontlock.
-
- AUCTeX is a standard package provided by XEmacs. You can get it as
-usual through the `M-x list-packages' interface. It is also included
-in the (non-Mule) SUMO package. The AUCTeX XEmacs package is
-maintained by Uwe Brauer <GET MAIL ADDRESS>.
-
- AUCTeX is extremely complicated, and its developers primarily use
-GNU Emacs. Not all features of the bleeding edge version of AUCTeX are
-immediately ported to XEmacs; if you need these, you may be better off
-getting the most recent versions from the GNU AUCTeX project on
-`http://savannah.gnu.org'.

-Q8.0.3: Problems installing AUCTeX.
------------------------------------
-
-Jan Vroonhof <vroonhof@math.ethz.ch> writes:
-
- AUCTeX works fine on both stock Emacs and XEmacs has been doing so
- for a very very long time. This is mostly due to the work of Per
- Abrahamsen <abraham@dina.kvl.dk> (clap clap) in particular his
- `easymenu' package. Which leads to what is probably the problem...
-
- Most problems with AUCTeX are one of two things:
-
- * The TeX-lisp-directory in `tex-site.el' and the makefile don't
- match.
-
- Fix: make sure you configure AUCTeX properly *before* installing.
-
- * You have an old version of easymenu.el in your path.
-
- Fix: use `locate-library' and remove old versions to make sure it
- *only* finds the one that came with XEmacs.

-Q8.0.4: How do I turn off current chapter from AUCTeX modeline?
----------------------------------------------------------------
-
-With AUCTeX, fast typing is hard because the current chapter, section
-etc. are given in the modeline. How can I turn this off?
-
- It's not AUCTeX, it comes from `func-menu' in `func-menu.el'.
-
- David Hughes <dhughes@origin-at.co.uk> writes:
-
- Try this; you'll still get the function name displayed in the
- modeline, but it won't attempt to keep track when you modify the
- file. To refresh when it gets out of synch, you simply need click
- on the `Rescan Buffer' option in the function-menu.

-8.1: Other Unbundled Packages
-=============================

-\1f
-File: xemacs-faq.info, Node: Q8.1.1, Next: Q8.1.2, Prev: Q8.0.4, Up: Other Packages
-
-Q8.1.1: Is there a reason for an Emacs package not to be included in XEmacs?
-----------------------------------------------------------------------------
-
-The reason for an Emacs package not to be included in XEmacs is usually
-one or more of the following:
-
- 1. The package has not been ported to XEmacs. This will typically
- happen when it uses GNU-Emacs-specific features, which make it
- fail under XEmacs.
-
- Porting a package to XEmacs can range from a trivial amount of
- change to a partial or full rewrite. Fortunately, the authors of
- modern packages usually choose to support both Emacsen themselves.
-
- 2. The package has been decided not to be appropriate for XEmacs. It
- may have an equivalent or better replacement within XEmacs, in
- which case the developers may choose not to burden themselves with
- supporting an additional package.
-
- Each package bundled with XEmacs means more work for the
- maintainers, whether they want it or not. If you are ready to
- take over the maintenance responsibilities for the package you
- port, be sure to say so--we will more likely include it.
-
- 3. The package simply hasn't been noted by the XEmacs development. If
- that's the case, the messages like yours are very useful for
- attracting our attention.
-
- 4. The package was noted by the developers, but they simply haven't
- yet gotten around to including/porting it. Wait for the next
- release or, even better, offer your help. It will be gladly
- accepted and appreciated.

-=====================================
-
-\1f
-File: xemacs-faq.info, Node: Q8.2.1, Next: Q8.2.2, Prev: Q8.1.3, Up: Other Packages
-
-Q8.2.1: What are SPARCworks, EOS, and WorkShop?
------------------------------------------------
-
-SPARCworks was a development environment from Sun (circa 1993-1996) and
-consisted of compilers (C, C++, FORTRAN 77, Fortran 90, Ada, and
-Pascal), a debugger, and other tools such as TeamWare (for
-configuration management), MakeTool, etc.
-
- EOS is the integration of XEmacs with the SPARCworks debugger. It
-allows one to use an XEmacs frame to view code (complete with
-fontification, etc.), set breakpoints, print variables, etc., while
-using the SPARCworks debugger.
-
- EOS stands for "Era on SPARCworks"; Era stood for "Emacs Rewritten
-Again" and was the name used by Sun for its modified version of Lucid
-Emacs (later XEmacs) in the early-mid 90's. This is documented in more
-detail in the history section of the XEmacs About page.
-
- EOS was replaced around 1996 with a newer graphical development
-environment called Sun WorkShop. The current status of this is unknown.

-
-Q8.2.2: How do I start the Sun Workshop support in XEmacs 21?
--------------------------------------------------------------
-
-Add the switch --with-workshop to the configure command when building
-XEmacs and put the following in one of your startup files (e.g.
-site-start.el or .emacs):
-
- (when (featurep 'tooltalk)
- (load "tooltalk-macros")
- (load "tooltalk-util")
- (load "tooltalk-init"))
- (when (featurep 'sparcworks)
- (load "sunpro-init")
- (load "ring")
- (load "comint")
- (load "annotations")
- (sunpro-startup))
-
- If you are not using the latest Workshop (5.0) you have to apply the
-following patch:

-Q8.2.3: What is/was Energize?
------------------------------
-
-The "Energize Programming System" was a C and C++ development
-environment sold by Lucid, Inc. It was the reason why Lucid Emacs, now
-XEmacs, was created in the first place. Unfortunately, Lucid went out
-of business in 1994. The rights to sell it in Japan were purchased by
-INS Engineering (which briefly employed Stig Hackvan aka Jonathan
-Stigelman to work on Japanese support for XEmacs, in late 1994 and
-early 1995) and Tartan bought the rights to sell it in the rest of the
-world. However, INS is not selling Energize at this point and may or
-may not have ever done so; Tartan certainly never did.

-Q8.2.4: What is Infodock?
--------------------------
-
-InfoDock (http://sourceforge.net/projects/infodock/) is an integrated
-productivity toolset, mainly aimed at technical people, hosted at
-SourceForge.
-
- InfoDock is built atop the XEmacs variant of GNU Emacs and so has
-all of the power of Emacs, but with an easier to use and more
-comprehensive menu-based user interface. The bottom portion of this
-text describes how it differs from XEmacs and GNU Emacs from the Free
-Software Foundation.
-
- InfoDock is aimed at people who want a free, turn-key productivity
-environment. Although InfoDock is customizable, it is not intended for
-people who like basic versions of Emacs which need to be customized
-extensively for local use; standard Emacs distributions are better for
-such uses. InfoDock is for those people who want a complete,
-pre-customized environment in one package, which they need not touch
-more than once or twice a year to update to new revisions.
-
- InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
-and Intel Linux systems. It is intended for use on a color display,
-although most features will work on monochrome monitors. Simply unpack
-InfoDock according to the instructions in the ID-INSTALL file and you
-are ready to run.
-
- The InfoDock Manual is concise, yet sufficient as a user guide for
-users who have never used an Emacs-type editor before. For users who
-are already familiar with Emacs, it supplements the information in the
-GNU Emacs Manual.
-
- InfoDock menus are much more extensive and more mature than standard
-Emacs menus. Each menu offers a `Manual' item which displays
-documentation associated with the menu's functions.
-
-Four types of menubars are provided:
- 1. An extensive menubar providing access to global InfoDock commands.
-
- 2. Mode-specific menubars tailored to the current major mode.
-
- 3. A simple menubar for basic editing to help novices get started
- with InfoDock.
-
- 4. The standard XEmacs menubar.
-
- Most modes also include mode-specific popup menus. Additionally,
-region and rectangle popup menus are included.
-
- `Hyperbole', the everyday information manager, is a core part of
-InfoDock. This provides context-sensitive mouse keys, a rolodex-type
-contact manager, programmable hypertext buttons, and an autonumbered
-outliner with embedded hyperlink anchors.
-
- The `OO-Browser', a multi-language object-oriented code browser, is a
-standard part of InfoDock.
-
- InfoDock saves a more extensive set of user options than other Emacs
-versions.
-
- InfoDock inserts a useful file header in many file types, showing the
-author, summary, and last modification time of each file. A summary
-program can then be used to summarize all of the files in a directory,
-for easy MANIFEST file creation.
-
- Your working set of buffers is automatically saved and restored (if
-you answer yes to a prompt) between InfoDock sessions.
-
- Refined color choices for code highlighting are provided for both
-dark and light background display frames.
-
- The `C-z' key prefix performs frame-based commands which parallel the
-`C-x' key prefix for window-based commands.
-
- The Smart Menu system is included for producing command menus on dumb
-terminals.
-
- Lisp libraries are better categorized according to function.
-
- Extensions and improvements to many areas of Emacs are included,
-such as: paragraph filling, mail reading with Rmail, shell handling,
-outlining, code highlighting and browsing, and man page browsing.
-
- InfoDock questions, answers and discussion should go to the mail list
-<infodock@infodock.com>. Use <infodock-request@infodock.com> to be
-added or removed from the list. Always include your InfoDock version
-number when sending help requests.

-Q9.0.2: What's new in XEmacs 21.4?
-----------------------------------
-
-21.4 was the "stable" version of the 21.2 series, which was considered
-"experimental" throughout its life; thus there were no "official"
-releases at all. In essence, XEmacs is now following the "alternating"
-scheme of Linux, where at any point there are at least two different
-development branches, one "stable" and one "experimental". Periodic
-releases happen in both branches, but those in the experimental branch
-are not tested as well, and there's no guarantee they will work at all.
-The experiemental branch is open to any and all code that's acceptable
-to the developers; the stable branch, however, is in general limited
-only to bug fixes, and all contributions are carefully reviewed to make
-sure they will increase and not decrease stability.
-
- 21.3 never existed at all; it was decided to follow the Linux scheme
-exactly, where odd-numbered series are experimental and even-numbered
-ones stable.
-
- The following lists summarizes the essential changes made in this
-version. For a fuller list, see the `NEWS' in the `etc' directory of
-the XEmacs distribution, or use `C-h n' or the `Help' menu to view this
-file inside of XEmacs.
-

- default values changes because you upgraded your XEmacs); `M-x
- add-log-convert' (converts an old-style ChangeLog buffer to
- new-style); `M-x zap-up-to-char' (like `zap-to-char' but doesn't
- delete the char searched for); commands to store, retrieve and
- increment numbers in registers, useful for macros.
-
- * *Changes to commands, variables, and functions*: `M-x
- query-replace' and friends operate only on the region when it's
- active; `echo-keystrokes' can now be a floating-point number; `M-.'
- searches exact tag matches before inexact ones; function
- `user-full-name' with no arguments returns the var
- `user-full-name'; a prefix arg to `M-:' and `C-h c' inserts the

- `scrollbar-on-top-p', `vertical-divider-always-visible-p',
- `vertical-divider-shadow-thickness',
- `vertical-divider-line-width', `vertical-divider-spacing';
- specifiers and symbols whose value is a specifier allowed as

-
- * *Frame focus changes*: `focus-follows-mouse' works like FSF,
- prevents any attempt to permanently change the selected frame; new
- function `focus-frame' sets the window system focus a frame; new
- special forms `save-selected-frame' and `with-selected-frame'.
-
- * *Window function changes*: `select-window' now has optional
- argument NORECORD to inhibit recording a buffer change;
- `vertical-motion' now correctly handles optional WINDOW argument
- and has new optional argument PIXELS, to have the returned values
- be in pixels; new function `vertical-motion-pixels'; new functions
- `window-text-area-pixel-{width,height,edges}'; new functions
- `shrink-window-pixels' and `enlarge-window-pixels'; new function
- `window-displayed-text-pixel-height'.
-
- * *Other function changes*: Arithmetic comparison functions `<',
- `>', `=', `/=' now accept a variable number of arguments;
- hashtables now have a consistent read/print syntax; keyword
- symbols cannot be set to a value other than themselves; `concat' no
- longer accepts integer arguments; new function `string', like
- `list', `vector', etc.; new function `temp-directory'
- (OS-independent way to get a temp directory); `load-average' has
- optional argument USE-FLOATS; `make-event' implemented completely;
- new function `function-interactive' (returns a function's
- interactive spec); new functions `lmessage', `lwarn' (printf-like
- versions of `display-wessage', `display-warning'); new keyword
- `:version' to `defcustom'.
-
- * *Performance*: when the new GNU Malloc aka Doug Lea Malloc is
- available, it will be used (better performance on libc6 Linux
- systems); tracking line-numbers in modeline is now efficient;
- profiling records a call-count of all called functions,
- retrievable through `profile-call-count-results'.
-
- * *Startup and path searching*: code to assemble paths at startup
- rewritten for new package system; new function `split-path' (splits
- by `path-separator'); `Info-default-directory-list' obsolete, use
- `Info-directory-list' instead; site-lisp is deprecated and no
- longer on the load-path by default.

-Q9.0.4: What's new in XEmacs 20.4?
-----------------------------------
-
-XEmacs 20.4 is a bugfix release with no user-visible changes.

-Q9.0.5: What's new in XEmacs 20.3?
-----------------------------------
-
-XEmacs 20.3 was released in November 1997. It contains many bugfixes,
-and a number of new features, including Autoconf 2 based configuration,
-additional support for Mule (Multi-language extensions to Emacs), many
-more customizations, multiple frames on TTY-s, support for multiple info
-directories, an enhanced gnuclient, improvements to regexp matching,
-increased MIME support, and many, many synches with GNU Emacs 20.
-
- The XEmacs/Mule support has been only seriously tested in a Japanese
-locale, and no doubt many problems still remain. The support for
-ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a
-price--about a 30% slowdown from 19.16. We're making progress on
-improving performance and XEmacs 20.3 compiled without Mule (which is
-the default) is definitely faster than XEmacs 19.16.
-
- XEmacs 20.3 is the first non-beta v20 release, and will be the basis
-for all further development.

-Q9.0.6: What's new in XEmacs 20.2?
-----------------------------------
-
-The biggest changes in 20.2 include integration of EFS (the next
-generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
-major mode for editing Tex and LaTeX, and a lot of other stuff). Many
-bugs from 20.0 have been fixed for this release. 20.2 also contains a
-new system for customizing XEmacs options, invoked via `M-x customize'.
-
- XEmacs 20.2 is the development release (20.0 was beta), and is no
-longer considered unstable.
-
- For older news, see the file `ONEWS' in the `etc' directory of the
-XEmacs distribution.

-10 New information about old XEmacsen
-*************************************
-
-This is part 10 of the XEmacs Frequently Asked Questions list. It will
-occasionally be updated to reflect new information about versions which
-are no longer being revised by the XEmacs Project. The primary purpose
-is advice on compatibility of older XEmacsen with new packages and
-updated versions of packages, but bug fixes (which will not be applied
-to released XEmacsen, but users can apply themselves) are also accepted.

- After a bit of sleuthing, I discovered the essence of the problem.
- For me, the form:
-
- (with-temp-buffer
- (insert-file-contents "foo.xpm")
- (buffer-string))
-
- returns the empty string. This is because something somewhere
- replaces the XPM data with a glyph -- I haven't figured out where
- this occurs.

-
- Do this:
-
- (setq format-alist nil)
-
- The image-mode stuff is gone from format-alist in the 21.4 branch,
- praise be.

-Q10.0.2: XEmacs won't start on Windows in XEmacs 21.1.
-------------------------------------------------------
-
-XEmacs relies on a process called "dumping" to generate a working
-executable. Under MS-Windows this process effectively fixes the memory
-addresses of information in the executable. When XEmacs starts up it
-tries to reserve these memory addresses so that the dumping process can
-be reversed - putting the information back at the correct addresses.
-Unfortunately some .DLLs (for instance the soundblaster driver) occupy
-memory addresses that can conflict with those needed by the dumped
-XEmacs executable. In this instance XEmacs will fail to start without
-any explanation. Note that this is extremely machine specific.
-
- 21.1.10 includes a fix for this that makes more intelligent guesses
-about which memory addresses will be free, and this should cure the
-problem for most people. 21.4 implements "portable dumping", which
-eliminates the problem altogether. We recommend you use the 21.4
-binaries, but you can use the 21.1 binaries if you are very paranoid
-about stability. *Note Are binaries available?: Q1.1.2.
