-Q2.0.3: Compiling XEmacs with Netaudio.
----------------------------------------
-
- What is the best way to compile XEmacs with the netaudio system,
-since I have got the netaudio system compiled but installed at a weird
-place, I am not root. Also in the READMEs it does not say anything
-about compiling with the audioserver?
-
- You should only need to add some stuff to the configure command line.
-To tell it to compile in netaudio support: `--with-sound=both', or
-`--with-sound=nas' if you don't want native sound support for some
-reason.) To tell it where to find the netaudio includes and libraries:
-
- --site-libraries=WHATEVER
- --site-includes=WHATEVER
-
- Then (fingers crossed) it should compile and it will use netaudio if
-you have a server running corresponding to the X server. The netaudio
-server has to be there when XEmacs starts. If the netaudio server goes
-away and another is run, XEmacs should cope (fingers crossed, error
-handling in netaudio isn't perfect).
-
- BTW, netaudio has been renamed as it has a name clash with something
-else, so if you see references to NAS or Network Audio System, it's the
-same thing. It also might be found at
-`ftp://ftp.x.org/contrib/audio/nas/'.

+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.
- No. The name "XEmacs" is unfortunate in the sense that it is *not*
-an X Window System-only version of Emacs. XEmacs has full color
-support on a color-capable character terminal.
+ 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>'),

+ Yeah, yeah, it has always worked for integer types, because fixnums

+---------------------------------------------
- Christopher Davis <ckd@loiosh.kei.com> writes:
+AUCTeX is a complex and sophisticated editing package dedicated to TeX

+files, and of course shortcuts for entering common TeX macros, LaTeX
+environments, etc, and for fontlock.
- That's correct [The SunOS 4.1.3 precompiled binaries don't do name
- lookup]. Since Sun figured that everyone used NIS to do name
- lookups (that DNS thing was apparently only a passing fad,
- right?), the stock SunOS 4.x systems don't have DNS-based name
- lookups in libc.
+ 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>.
- This is also why Netscape ships two binaries for SunOS 4.1.x.
-
- The best solution is to compile it yourself; the configure script
- will check to see if you've put DNS in the shared libc and will
- then proceed to link against the DNS resolver library code.
+ AUCTeX is extremely complicated, and its developers primarily use
+GNU Emacs. Not all features of the bleeding edge version of AUCTeX are

------------------------------------------
+File: xemacs-faq.info, Node: Q8.1.1, Next: Q8.1.2, Prev: Q8.0.4, Up: Other Packages
- First of all, don't panic. Whenever XEmacs crashes, it tries
-extremely hard to auto-save all of your files before dying. (The main
-time that this will not happen is if the machine physically lost power
-or if you killed the XEmacs process using `kill -9'). The next time
-you try to edit those files, you will be informed that a more recent
-auto-save file exists. You can use `M-x recover-file' to retrieve the
-auto-saved version of the file.
+Q8.1.1: Is there a reason for an Emacs package not to be included in XEmacs?
+----------------------------------------------------------------------------
- You can use the command `M-x recover-session' after a crash to pick
-up where you left off.
+The reason for an Emacs package not to be included in XEmacs is usually
+one or more of the following:
- Now, XEmacs is not perfect, and there may occasionally be times, or
-particular sequences of actions, that cause it to crash. If you can
-come up with a reproducible way of doing this (or even if you have a
-pretty good memory of exactly what you were doing at the time), the
-maintainers would be very interested in knowing about it. Post a
-message to comp.emacs.xemacs or send mail to <crashes@xemacs.org>.
-Please note that the `crashes' address is exclusively for crash reports.
+ 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.
- If at all possible, include a stack backtrace of the core dump that
-was produced. This shows where exactly things went wrong, and makes it
-much easier to diagnose problems. To do this, you need to locate the
-core file (it's called `core', and is usually sitting in the directory
-that you started XEmacs from, or your home directory if that other
-directory was not writable). Then, go to that directory and execute a
-command like:
+ 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.
- gdb `which xemacs` core
+ 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.
- and then issue the command `where' to get the stack backtrace. You
-might have to use `dbx' or some similar debugger in place of `gdb'. If
-you don't have any such debugger available, complain to your system
-administrator.
+ 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.
- It's possible that a core file didn't get produced, in which case
-you're out of luck. Go complain to your system administrator and tell
-him not to disable core files by default. Also *Note Q2.1.15::, for
-tips and techniques for dealing with a debugger.
+ 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.
- When making a problem report make sure that:
-
- 1. Report *all* of the information output by XEmacs during the crash.
-
- 2. You mention what O/S & Hardware you are running XEmacs on.
-
- 3. What version of XEmacs you are running.
-
- 4. What build options you are using.
-
- 5. If the problem is related to graphics, we will also need to know
- what version of the X Window System you are running, and what
- window manager you are using.
-
- 6. If the problem happened on a tty, please include the terminal type.
+ 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.

- There are two causes of this problem. The first usually only strikes

-
- * The binary cannot find the `XKeysymDB' file. The location is

- puts it a different place than your system does, you have
- problems. To fix, set the environment variable XKEYSYMDB to the
- location of the `XKeysymDB' file on your system or to the location
- of the one included with XEmacs which should be at
- `<xemacs_root_directory>/lib/xemacs-19.16/etc/XKeysymDB'.
-
- * The binary is finding the XKeysymDB but it is out-of-date on your
- system and does not contain the necessary lines. Either ask your

+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.
-Q2.1.6: XEmacs just locked up my Linux X server!
-------------------------------------------------
+ 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.
- There have been several reports of the X server locking up under
-Linux. In all reported cases removing speedo and scaled fonts from the
-font path corrected the problem. This can be done with the command
-`xset'.
+ 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.
- It is possible that using a font server may also solve the problem.
+ EOS was replaced around 1996 with a newer graphical development
+environment called Sun WorkShop. The current status of this is unknown.

-Q2.1.15: How to Debug an XEmacs problem with a debugger
--------------------------------------------------------
-
- If XEmacs does crash on you, one of the most productive things you
-can do to help get the bug fixed is to poke around a bit with the
-debugger. Here are some hints:
-
- * First of all, if the crash is at all reproducible, consider very
- strongly recompiling your XEmacs with debugging symbols, with no
- optimization, and with the configure options `--debug=yes' and
- `--error-checking=all'. This will make your XEmacs run somewhat
- slower but make it a lot more likely to catch the problem earlier
- (closer to its source), and a lot easier to determine what's going
- on with a debugger.
-
- * If you're able to run XEmacs under a debugger and reproduce the
- crash (if it's inconvenient to do this because XEmacs is already
- running or is running in batch mode as part of a bunch of scripts,
- consider attaching to the existing process with your debugger;
- most debuggers let you do this by substituting the process ID for
- the core file when you invoke the debugger from the command line,
- or by using the `attach' command or something similar), here are
- some things you can do:
-
- * If XEmacs is hitting an assertion failure, put a breakpoint on
- `assert_failed()'.
-
- * If XEmacs is hitting some weird Lisp error that's causing it to
- crash (e.g. during startup), put a breakpoint on
- `signal_1()'--this is declared static in eval.c.
-
- * Internally, you will probably see lots of variables that hold
- objects of type `Lisp_Object'. These are exactly what they appear
- to be, i.e. references to Lisp objects. Printing them out with
- the debugger probably won't be too useful--you'll likely just see
- a number. To decode them, do this:
-
- call debug_print (OBJECT)
-
- where OBJECT is whatever you want to decode (it can be a variable,
- a function call, etc.). This will print out a readable
- representation on the TTY from which the xemacs process was
- invoked.
-
- * If you want to get a Lisp backtrace showing the Lisp call stack,
- do this:
-
- call debug_backtrace ()
-
- * Using `debug_print' and `debug_backtrace' has two disadvantages -
- it can only be used with a running xemacs process, and it cannot
- display the internal C structure of a Lisp Object. Even if all
- you've got is a core dump, all is not lost.
-
- If you're using GDB, there are some macros in the file
- `src/.gdbinit' in the XEmacs source distribution that should make
- it easier for you to decode Lisp objects. This file is
- automatically read by gdb if gdb is run in the directory where
- xemacs was built, and contains these useful macros to inspect the
- state of xemacs:
-
- `pobj'
- Usage: pobj lisp_object
- Print the internal C representation of a lisp object.
-
- `xtype'
- Usage: xtype lisp_object
- Print the Lisp type of a lisp object.
-
- `lbt'
- Usage: lbt
- Print the current Lisp stack trace. Requires a running
- xemacs process.
-
- `ldp'
- Usage: ldp lisp_object
- Print a Lisp Object value using the Lisp printer. Requires a
- running xemacs process.
-
- `run-temacs'
- Usage: run-temacs
- Run temacs interactively, like xemacs. Use this with
- debugging tools (like purify) that cannot deal with dumping,
- or when temacs builds successfully, but xemacs does not.
-
- `dump-temacs'
- Usage: dump-temacs
- Run the dumping part of the build procedure. Use when
- debugging temacs, not xemacs! Use this when temacs builds
- successfully, but xemacs does not.
-
- `check-xemacs'
- Usage: check-xemacs
- Run the test suite. Equivalent to 'make check'.
-
- `check-temacs'
- Usage: check-temacs
- Run the test suite on temacs. Equivalent to 'make
- check-temacs'. Use this with debugging tools (like purify)
- that cannot deal with dumping, or when temacs builds
- successfully, but xemacs does not.
-
- If you are using Sun's `dbx' debugger, there is an equivalent file
- `src/.dbxrc', which defines the same commands for dbx.
-
- * If you're using a debugger to get a C stack backtrace and you're
- seeing stack traces with some of the innermost frames mangled, it
- may be due to dynamic linking. (This happens especially under
- Linux.) Consider reconfiguring with `--dynamic=no'. Also,
- sometimes (again under Linux), stack backtraces of core dumps will
- have the frame where the fatal signal occurred mangled; if you can
- obtain a stack trace while running the XEmacs process under a
- debugger, the stack trace should be clean.
-
- Curtiss <1CMC3466@ibm.mtsac.edu> suggests upgrading to ld.so
- version 1.8 if dynamic linking and debugging is a problem on Linux.
-
- * If you're using a debugger to get a C stack backtrace and you're
- getting a completely mangled and bogus stack trace, it's probably
- due to one of the following:
-
- a. Your executable has been stripped. Bad news. Tell your
- sysadmin not to do this--it doesn't accomplish anything
- except to save a bit of disk space, and makes debugging much
- much harder.
-
- b. Your stack is getting trashed. Debugging this is hard; you
- have to do a binary-search type of narrowing down where the
- crash occurs, until you figure out exactly which line is
- causing the problem. Of course, this only works if the bug
- is highly reproducible.
-
- c. If your stack trace has exactly one frame in it, with address
- 0x0, this could simply mean that XEmacs attempted to execute
- code at that address, e.g. through jumping to a null function
- pointer. Unfortunately, under those circumstances, GDB under
- Linux doesn't know how to get a stack trace. (Yes, this is
- the third Linux-related problem I've mentioned. I have no
- idea why GDB under Linux is so bogus. Complain to the GDB
- authors, or to comp.os.linux.development.system). Again,
- you'll have to use the narrowing-down process described above.
-
- d. You will get a Lisp backtrace output when XEmacs crashes, so
- you'll have something useful.
-
-
- * If you compile with the newer gcc variants gcc-2.8 or egcs, you
- will also need gdb 4.17 or above. Earlier releases of gdb can't
- handle the debug information generated by the newer compilers.
-
- * In versions of XEmacs before 21.2.27, `src/.gdbinit' was named
- `src/gdbinit'. This had the disadvantage of not being sourced
- automatically by gdb, so you had to set that up yourself.

+Q9.0.2: What's new in XEmacs 21.4?
+----------------------------------
- Two things you can do:
+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.
- 1) C level:
+ 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.
- When you see it going mad like this, you might want to use gdb
- from an 'xterm' to attach to the running process and get a stack
- trace. To do this just run:
+ 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.
- gdb /path/to/xemacs/xemacs ####
+User-visible changes in XEmacs 21.4
+...................................
- Where `####' is the process id of your xemacs, instead of
- specifying the core. When gdb attaches, the xemacs will stop [1]
- and you can type `where' in gdb to get a stack trace as usual. To
- get things moving again, you can just type `quit' in gdb. It'll
- tell you the program is running and ask if you want to quit
- anyways. Say 'y' and it'll quit and have your emacs continue from
- where it was at.
+ * The delete key now deletes forward by default.
- 2) Lisp level:
+ * Shifted motion keys now select text by default.
- Turn on debug-on-quit early on. When you think things are going
- slow hit C-g and it may pop you in the debugger so you can see
- what routine is running. Press `c' to get going again.
+ * You can now build XEmacs with support for GTK+ widget set.
- debug-on-quit doesn't work if something's turned on inhibit-quit
- or in some other strange cases.
+ * ~/.xemacs/init.el is now the preferred location for the init file.
+ (XEmacs now supports a `~/.xemacs/init.el' startup file. Custom
+ file will move to ~/.xemacs/custom.el.)
-\1f
-File: xemacs-faq.info, Node: Q2.1.23, Next: Q2.1.24, Prev: Q2.1.22, Up: Installation
+ * Much-improved sample init.el, showing how to use many useful
+ features.
-Q2.1.23: Movemail on Linux does not work for XEmacs 19.15 and later.
----------------------------------------------------------------------
+ * XEmacs support for menu accelerators has been much improved.
- Movemail used to work fine in 19.14 but has stopped working in 19.15
-and 20.x. I am using Linux.
+ * Default menubar improvements. (Default menubar has many new
+ commands and better organization. The font-menu is now available
+ under MS Windows.)
- SL Baur <steve@xemacs.org> writes:
+ * Dialog box improvements, including a real file dialog box. (XEmacs
+ now has a proper file dialog box under MS Windows (and GTK)! The
+ old clunky file dialog box is improved. Keyboard traversal now
+ works correctly in MS Windows dialog boxes. There is a Search
+ dialog box available from `Edit->Find...')
- Movemail on Linux used to default to using flock file locking.
- With 19.15 and later versions it now defaults to using `.lock' file
- locking. If this is not appropriate for your system, edit
- src/s/linux.h and uncomment the line that reads:
+ * New buffer tabs.
- #define MAIL_USE_FLOCK
+ * There is a new MS Windows installer, netinstall, ported from

-Q2.1.24: XEmacs won't start without network. (NEW)
----------------------------------------------------
+ * Printing support now available under MS Windows.
- If XEmacs starts when you're on the network, but fails when you're
-not on the network, you may be missing a "localhost" entry in your
-`/etc/hosts' file. The file should contain an entry like:
+ * Selection improvements. (Kill and yank now interact with the
+ clipboard under Windows. MS Windows support for selection is now
+ much more robust. Motif selection support is now more correct
+ (but slower).)
- 127.0.0.1 localhost
+ * Mail spool locking now works correctly.
- Add that line, and XEmacs will be happy.
+ * International support changes. (The default coding-priority-list
+ is now safer. International keysyms are now supported under X.
+ MS Windows 1251 code page now supported. Czech, Thai,
+ Cyrillic-KOI8, Vietnamese, Ethiopic now supported. Proper support
+ for words in Latin 3 and Latin 4.)

-Q2.1.25:: After upgrading, XEmacs won't do `foo' any more! (NEW)
------------------------------------------------------------------
+ * The modeline's text is now scrollable.
- You have been used to doing `foo', but now when you invoke it (or
-click the toolbar button or select the menu item), nothing (or an error)
-happens. The simplest explanation is that you are missing a package
-that is essential to you. You can either track it down and install it
-(there is a list of packages and brief descriptions of their contents in
-`etc/PACKAGES'), or install the `Sumo Tarball' (see *note Q2.0.14::).

-======================================================
+ * Operation progress can be displayed using graphical widgets.
-Q3.0.1: What version of Emacs am I running?
--------------------------------------------
+ * User names following a tilde can now be completed at file name
+ prompts.
- How can `init.el'/`.emacs' determine which of the family of Emacsen
-I am using?
+ * XEmacs can now play sound using Enlightenment Sound Daemon (ESD).
- To determine if you are currently running GNU Emacs 18, GNU Emacs 19,
-XEmacs 19, XEmacs 20, or Epoch, and use appropriate code, check out the
-example given in `etc/sample.init.el' (`etc/sample.emacs' in XEmacs
-versions prior to 21.4). There are other nifty things in there as well!
+ * X-Face support is now available under MS Windows.
- For all new code, all you really need to do is:
+ * The PostgreSQL Relational Database Management System is now
+ supported.
- (defvar running-xemacs (string-match "XEmacs\\|Lucid" emacs-version))
+ * Indentation no longer indents comments that begin at column zero.

---------------------------------------------------
+ * New locations for early package hierarchies.
- I know I can evaluate Elisp expressions from `*scratch*' buffer with
-`C-j' after the expression. How do I do it from another buffer?
+ * The `auto-save' library has been greatly improved.
- Press `M-:' (the default binding of `eval-expression'), and enter
-the expression to the minibuffer.
+ * New variable `mswindows-alt-by-itself-activates-menu'.

+ -user-init-file and -user-init-directory.)
-Q3.0.3: `(setq tab-width 6)' behaves oddly.
--------------------------------------------
+ * Etags changes. See `NEWS' for full details.
- If you put `(setq tab-width 6)' in your `init.el'/`.emacs' file it
-does not work! Is there a reason for this? If you do it at the EVAL
-prompt it works fine!! How strange.
+Lisp and internal changes in XEmacs 21.4

------------------------------------------------------
-
- Here are two ways to do that, one that puts your directories at the
-front of the load-path, the other at the end:
-
- ;;; Add things at the beginning of the load-path, do not add
- ;;; duplicate directories:
- (pushnew "bar" load-path :test 'equal)
-
- (pushnew "foo" load-path :test 'equal)

+
+User-visible changes in XEmacs 21.1
+...................................
+
+ * XEmacs is now supported under Microsoft Windows 95/98 and Windows
+ NT/2000/XP operating systems. To discuss Windows-specific issues,
+ subscribe to the mailing list at <xemacs-winnt-request@xemacs.org>.
+
+ * XEmacs has been unbundled into constituent installable packages.
+
+ * *Other notable changes*: The `Options' menu has been ported to
+ Custom; XEmacs now is able to choose X visuals and use private
+ colormaps; You can drag the vertical divider of "horizontally"
+ (side-by-side) split windows.
+
+ * *Building changes*: XEmacs can be built with support for 31-bit
+ Lisp integers and 32-bit pointers (previously, it was 28-bit
+ integers and pointers); XEmacs can be built with LDAP support;
+ `dir' files can be removed in the Info subsystem, and will be
+ regenerated on-the-fly.
+
+ * *New packages*: `imenu', `popper', `gdb-highlight'
+
+ * *Package changes*: Many changes to `cc-mode', `gnus', `gnuclient'.
+ See `NEWS' for full details.
+
+ * *New commands, variables and functions*: `center-to-window-line'
+ (like `recenter' but doesn't force a redisplay); variable
+ `user-full-name' (customize what your full name looks like in
+ mail); `M-x customize-changed-options' (customize options whose
+ 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
+ result in the current buffer.
+
+ * *Other changes*: Under X, new application class `XEmacs';
+ byte-compilation of user-specs now works.
+
+ * *XEmacs/Mule (internationalization) changes*: Mule support now
+ works on TTY's; Egg/SJ3 input method now officially supported

+ `vertical-divider-line-width', `vertical-divider-spacing';
+ specifiers and symbols whose value is a specifier allowed as
+ modeline specifications.
+
+ * *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'.

+ 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.

----------------------------------------------------
+File: xemacs-faq.info, Node: Q9.0.5, Next: Q9.0.6, Prev: Q9.0.4, Up: Current Events
- Use the following elisp:
-
- (fboundp 'foo)
-
- It's almost always a mistake to test `emacs-version' or any similar
-variables.
+Q9.0.5: What's new in XEmacs 20.3?
+----------------------------------
- Instead, use feature-tests, such as `featurep', `boundp', `fboundp',
-or even simple behavioral tests, eg.:
+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.
- (defvar foo-old-losing-code-p
- (condition-case nil (progn (losing-code t) nil)
- (wrong-number-of-arguments t)))
+ 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.
- There is an incredible amount of broken code out there which could
-work much better more often in more places if it did the above instead
-of trying to divine its environment from the value of one variable.
+ XEmacs 20.3 is the first non-beta v20 release, and will be the basis
+for all further development.

-Q3.0.6: Can I force the output of `(face-list)' to a buffer?
-------------------------------------------------------------
+Q9.0.6: What's new in XEmacs 20.2?
+----------------------------------
- It would be good having it in a buffer, as the output of
-`(face-list)' is too wide to fit to a minibuffer.
+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'.
- Evaluate the expression in the `*scratch*' buffer with point after
-the rightmost paren and typing `C-j'.
+ XEmacs 20.2 is the development release (20.0 was beta), and is no
+longer considered unstable.
- If the minibuffer smallness is the only problem you encounter, you
-can simply press `C-h l' to get the former minibuffer contents in a
-buffer.
+ For older news, see the file `ONEWS' in the `etc' directory of the
+XEmacs distribution.

-Q3.0.9: What is `Customize'?
-----------------------------
+Q10.0.1: Gnus 5.10 won't display smileys in XEmacs 21.1.

- Starting with XEmacs 20.2 there is new system 'Customize' for

+ After a bit of sleuthing, I discovered the essence of the problem.
+ For me, the form:
-3.1: X Window System & Resources
-================================
+ (with-temp-buffer
+ (insert-file-contents "foo.xpm")
+ (buffer-string))
-Q3.1.1: Where is a list of X resources?
----------------------------------------
+ returns the empty string. This is because something somewhere
+ replaces the XPM data with a glyph -- I haven't figured out where
+ this occurs.
- Search through the `NEWS' file for `X Resources'. A fairly
-comprehensive list is given after it.
+ Kyle Jones <kyle_jones@wonderworks.com> replies:
- In addition, an `app-defaults' file is supplied, `etc/Emacs.ad'
-listing the defaults. The file `etc/sample.Xdefaults' gives a set of
-defaults that you might consider. It is essentially the same as
-`etc/Emacs.ad' but some entries are slightly altered. Be careful about
-installing the contents of this file into your `.Xdefaults' or
-`.Xresources' file if you use GNU Emacs under X11 as well.

-Q3.1.2: How can I detect a color display?
------------------------------------------
-
- You can test the return value of the function `(device-class)', as
-in:
+ (setq format-alist nil)
- (when (eq (device-class) 'color)
- (set-face-foreground 'font-lock-comment-face "Grey")
- (set-face-foreground 'font-lock-string-face "Red")
- ....
- )
+ The image-mode stuff is gone from format-alist in the 21.4 branch,
+ praise be.

+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.
