+
+BUILDING AND INSTALLATION:
+
+1) Make sure your system has enough swapping space allocated to handle
+a program whose pure code is 900k bytes and whose data area is at
+least 400k and can reach 8Mb or more.  If the swapping space is
+insufficient, you will get an error in the command `temacs -batch -l
+loadup dump', found in `./src/Makefile.in.in', or possibly when
+running the final dumped XEmacs.
+ 
+Building XEmacs requires about 70 Mb of disk space (including the
+XEmacs sources).  Once installed, XEmacs occupies about 50 Mb in the
+file system where it is installed; this includes the executable files,
+Lisp libraries, miscellaneous data files, and on-line documentation.
+If the building and installation take place in different directories,
+then the installation procedure momentarily requires 70+50 Mb.
+
+XEmacs requires an ANSI C compiler, such as LCC or GCC.
+
+2) Consult `./etc/MACHINES' to see what configuration name you should
+give to the `configure' program.  That file offers hints for
+getting around some possible installation problems.
+
+3) In the top directory of the XEmacs distribution, run the program
+`configure' as follows:
+
+    ./configure CONFIGURATION-NAME [--OPTION[=VALUE]] ...
+
+The CONFIGURATION-NAME argument should be a configuration name given
+in `./etc/MACHINES'.  If omitted, `configure' will try to guess your
+system type; if it cannot, you must find the appropriate configuration
+name in `./etc/MACHINES' and specify it explicitly.
+
+If you don't want X support, specify `--with-x=no'.  If you omit this
+option, `configure' will try to figure out for itself whether your
+system has X, and arrange to use it if present.
+
+Additional support can be included for the NeXTstep system by
+specifying the flag `--with-ns'.  This is not yet fully supported.
+
+The `--x-includes=DIR' and `--x-libraries=DIR' options tell the build
+process where the compiler should look for the include files and
+object libraries used with the X Window System.  Normally, `configure'
+is able to find them; these options are necessary if you have your X
+Window System files installed in unusual places.
+
+The `--site-includes=DIR' and `--site-libraries=DIR' options allow you
+to specify additional places the compiler should look for include
+files and object libraries.  You may specify multiple DIR's by
+enclosing the list in quotes.  On some systems (noticeably Solaris) you
+may need to use `--site-runtime-libraries=DIR'.  This will add -R
+versions of each path in addition to the -L versions.
+
+The `--with-gcc' option specifies that the build process should
+compile XEmacs using GCC.  The `--with-lcc' option specifies that the
+build process should compile XEmacs using Lucid C.  The `--compiler'
+option allows you to specify some other compiler to be used to compile
+XEmacs.  It is compatible with both the `--with-gcc' and `--with-lcc'
+options, so if the compiler that you specify is a special version of
+either gcc or lcc, then use the appropriate --with-gcc or --with-lcc
+flag as well as the --compiler flag.  If none of these flags is
+specified, `configure' will search for GCC in your load path, and use
+it if present.  If you don't want to use GCC, specify `--with-gcc=no'
+and the compiler will then default to 'cc'.
+
+The `--cflags' option specifies the CFLAGS the build process should
+use when compiling XEmacs.  If not used CFLAGS defaults to "-g -O" for
+gcc and "-g" for all other compilers.
+
+The `--with-gnu-make' option specifies that Makefiles should be
+written to take advantage of special features of GNU Make.  GNU Make
+works fine on Makefiles even without this option.  This flag just
+allows for simultaneous in-place and --srcdir building.
+
+The `--dynamic' option specifies that configure should try to link
+emacs dynamically rather than statically.
+
+The `--const-is-losing' option is for use if you have trouble
+compiling due to the `const' storage class in C.  This is defined by 
+default.  Most users should have no need to change this.
+
+You can build XEmacs for several different machine types from a single
+source directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  Make separate
+build directories for the different configuration types, and in each
+one, run the XEmacs `configure' script.  `configure' looks for the
+Emacs source code in the directory that `configure' is in.
+
+The `--prefix=PREFIXDIR' option specifies where the installation process
+should put XEmacs and its data files.  This defaults to `/usr/local'.
+- XEmacs (and the other utilities users run) go in PREFIXDIR/bin
+  (unless the `--exec-prefix' option says otherwise).
+- The architecture-independent files go in PREFIXDIR/lib/xemacs-VERSION
+  (where VERSION is the version number of XEmacs, like `19.14').
+- The architecture-dependent files go in
+  PREFIXDIR/lib/xemacs-VERSION/CONFIGURATION
+  (where CONFIGURATION is the configuration name, like mips-dec-ultrix4.2),
+  unless the `--exec-prefix' option says otherwise.
+
+The `--exec-prefix=EXECDIR' option allows you to specify a separate
+portion of the directory tree for installing architecture-specific
+files, like executables and utility programs.  If specified,
+- XEmacs (and the other utilities users run) go in EXECDIR/bin, and
+- The architecture-dependent files go in
+  EXECDIR/lib/xemacs-VERSION/CONFIGURATION.
+EXECDIR/bin should be a directory that is normally in users' PATHs.
+
+For example, the command
+
+    ./configure mips-dec-ultrix --with-x
+
+configures XEmacs to build for a DECstation running Ultrix, with
+support for the X11 window system.
+
+The `--run-in-place' option will make the installed binaries reference
+the source tree for the elisp files.
+
+The `--with-menubars=TYPE' option allows you to specify which X
+toolkit you wish to use for the menubar.  The valid options are
+`lucid', `motif' and `none'.  The default is `lucid' which is a
+Motif-lookalike menubar.  We highly recommend its usage over the real
+Motif menubar. (In fact, the Motif menubar is currently broken.)  If
+`none' is specified then support for menubars will not be compiled in.
+
+The `--with-scrollbars=TYPE' option allows you to specify which X
+toolkit you wish to use for the scrollbars.  The valid options are
+`lucid', `motif', `athena' and `none'.  The default is `lucid' which
+is a Motif-lookalike scrollbar.  If `none' is specified then support
+for scrollbars will not be compiled in.
+
+The `--with-dialogs=TYPE' option allows you to specify which X toolkit
+you wish to use for the scrollbars.  The valid options are `athena',
+`motif, and `none.  The `lucid' option is accepted and will result in
+the `athena' toolkit being used.  If the Motif toolkit can be found
+the default is `motif'.  Otherwise, the default is `athena'.  If
+`none' is specified then support for dialog boxes will not be compiled
+in.
+
+The `--with-toolbars' option allows you to enable or disable toolbar
+support.  The default is `yes' as long as support for a windowing
+system is included.
+
+The `--with-xpm' option specifies that XEmacs should support X
+Pixmaps.  `configure' will attempt to detect if you have the Xpm
+libraries and define `--with-xpm' for you.
+
+The `--with-xface' option specifies that XEmacs should support
+X-Faces.  `configure' will attempt to detect if you have the compface
+library and define `--with-xface' for you.
+
+The `--with-gif' option specifies that XEmacs should support GIF image
+conversion.  No extra libraries are required.  This options defaults
+to `yes'.
+
+The `--with-jpeg' option specifies that XEmacs should support JPEG
+image conversion.  This option requires libjpeg from the Independent
+JPEG Group which is available on the XEmacs ftp site.  `configure'
+will attempt to detect if you have libjpeg and define `--with-jpeg'
+for you.
+
+The `--with-png option specifies that XEmacs should support PNG image
+conversion.  The valid options at `yes', `no' and `gnuz'.  This option
+requires libpng which is available on the XEmacs ftp site.  This
+option also requires a decompression library, either libz or libgz.
+The default is to use libz.  Specify `gnuz' as the option to use libgz
+instead.  `configure' will attempt to detect if you have libpng and
+define `--with-png' for you.
+
+The `--with-database' option specifies that XEmacs should be built
+with additional database support.  The valid options are `no' or a
+comma-separated list of one or more of `dbm', `gnudbm' or `berkdb'.
+`configure' will attempt to detect the necessary libraries and header
+files and define `--with-database' for you.
+
+The `--with-socks' option specifies that XEmacs should be built with
+SOCKS support.
+
+The `--with-term' option specifies that XEmacs should be built with
+TERM support.  TERM is a way to multiplex serial lines over a simple
+dialup connection, used on Linux and other systems.  We cannot
+guarantee that our TERM support coexists well with standard Internet
+connections.
+
+The `--with-tooltalk' option specifies that XEmacs should be built
+with ToolTalk support for interconnecting with other applications.
+ToolTalk is not yet supported on all architectures.
+
+The `--with-sparcworks' option specifies that XEmacs should be built
+with support for Sun Sparcworks 3.0.1 and up.  This functionality is
+only of use on SunOS 4.1.x and Solaris 2.x systems.
+
+The `--with-cde option allows you to enable or disable CDE drag and
+drop support.  `configure' will attempt to detect this option and
+define `--with-cde' for you.
+
+The `--with-energize' option specifies that XEmacs should be built
+with support for the Lucid Energize system.  (If you have not
+purchased Energize, specifying this option won't gain you anything.)
+Currently this doesn't work.
+
+The `--external-widget' option specifies that XEmacs should be built
+with support for being used as a widget.  This functionality should be
+considered beta.
+
+The `--with-mocklisp' option specifies that XEmacs should be built
+with support for Mocklisp.  Do not use this option unless you have a
+Mocklisp program that you need to run.
+
+The `--with-xmu=no' option can be used if your vendor doesn't ship
+the Xmu library.
+
+The `--puresize' option can be used to change the amount of purespace
+allocated for the dumped XEmacs.
+
+The `--with-sound=TYPE' option specifies that XEmacs should be built
+with sound support.  Native (`--with-sound=native') sound support is
+currently available only on Sun SparcStations, SGI's, HP9000s, and
+Linux.  Network Audio Support (NAS) (`--with-sound=nas' or
+`--with-sound=both') is an extension to X that you may or may not have
+for your system.  For NAS, you will probably need to provide the paths
+to the nas include and library directories to configure.  `configure'
+will attempt to determine if your configuration supports sound and
+define --with-sound for you.  If your native sound library is not in a
+standard location you can specify where it is with the
+`--native-sound-lib=LIB' flag.  For Linux, `/dev/audio' is required
+for SunAudio files and `/dev/dsp' is required for raw data and WAVE
+format files.
+
+The `--rel-alloc' option can be used to either enable or disable use
+of the relocating allocator.  Generally, it's best to go with the
+default configuration for your system.
+
+The `--use-system-malloc' option can be use to either enable or
+disable use of the relocating allocator.  Generally, it's best to go
+with the default configuration for your system.  Note that on many
+systems using the system malloc disables the use of the relocating
+allocator.
+
+The `--with-epoch' option enables functionality taken from Epoch.
+Currently this doesn't work.
+
+The `--debug' and `--error-checking' options are intended for use only
+by the developers.  `--debug' adds code to be compiled in for
+performing various tests.  `--error-checking' adds additional tests to
+many of the commonly used macros.
+
+The `--verbose' and `--extra-verbose' options are intended for use
+only by the developers.  `--verbose' causes the results of all
+configure tests to be displayed.  `--extra-verbose' also displays the
+output of any compiler invocations done by configure.
+
+`configure' doesn't do any compilation or installation
+itself.  It just creates the files that influence those things:
+`./Makefile', `src/Makefile', `lwlib/Makefile', `lib-src/Makefile',
+`man/Makefile', `dynodump/Makefile', and `./src/config.h'.  For
+details on exactly what it does, see the section called `CONFIGURATION
+BY HAND', below.
+
+When it is done, `configure' prints a description of what it did and
+creates a shell script `config.status' which, when run, recreates the
+same configuration.  If `configure' exits with an error after
+disturbing the status quo, it removes `config.status'.
+
+The work of `configure' can be done by editing various files in the
+distribution, but using `configure' is supposed to be simpler.  See
+the section called "CONFIGURATION BY HAND" below if you want to do the
+configuration yourself.
+
+4) Look at `./lisp/paths.el'; if some of those values are not right
+for your system, set up the file `./lisp/site-init.el' with XEmacs
+Lisp code to override them; it is not a good idea to edit paths.el
+itself.  YOU MUST USE THE LISP FUNCTION `setq' TO ASSIGN VALUES,
+rather than `defvar', as used by `./lisp/paths.el'.  For example,
+
+     (setq news-inews-program "/usr/bin/inews")
+
+is how you would override the default value of the variable
+news-inews-program (which is "/usr/local/inews").
+
+Before you override a variable this way, *look at the value* that the
+variable gets by default!  Make sure you know what kind of value the
+variable should have.  If you don't pay attention to what you are
+doing, you'll make a mistake.
+
+Things may malfunction if the variable `directory-abbrev-alist' is not set
+up to translate "temporary" automounter mount points into the canonical
+form.  The default value of this variable contains the translation
+
+	("^/tmp_mnt/" . "/")
+
+meaning translate "/tmp_mnt/net/FOO" into "/net/FOO", which is appropriate
+for the default configuration of the Sun automounter, but which may be
+inappropriate for different vendor's automounters, or if you have customized
+your mount-point names.
+
+5) Put into `./lisp/site-init.el' or `./lisp/site-load.el' any Emacs
+Lisp code you want XEmacs to load before it is dumped out.  Use
+site-load.el for additional libraries if you arrange for their
+documentation strings to be in the lib-src/DOC file (see
+src/Makefile.in.in if you wish to figure out how to do that).  For all
+else, use site-init.el.
+
+If you set load-path to a different value in site-init.el or
+site-load.el, XEmacs will use *precisely* that value when it starts up
+again.  If you do this, you are on your own!
+
+Note that, on some systems, the code you place in site-init.el must
+not use expand-file-name or any other function which may look
+something up in the system's password and user information database.
+See `./PROBLEMS' for more details on which systems this affects.
+
+The `site-*.el' files are nonexistent in the distribution.  You do not
+need to create them if you have nothing to put in them.
+
+6) Refer to the file `./etc/TERMS' for information on fields you may
+wish to add to various termcap entries.  The files `./etc/termcap.ucb'
+and `./etc/termcap.dat' may already contain appropriately-modified
+entries.
+
+7) Run `make' in the top directory of the XEmacs distribution to finish
+building XEmacs in the standard way.  The final executable file is
+named `src/emacs'.  You can execute this file "in place" without
+copying it, if you wish; then it automatically uses the sibling
+directories ../lisp, ../lib-src, ../info.
+
+Or you can "install" the executable and the other XEmacs into their
+installed locations, with `make install'.  By default, XEmacs's files
+are installed in the following directories:
+
+By default, XEmacs installs its files in the following directories:
+
+`/usr/local/bin' holds the executable programs users normally run -
+		`xemacs', `etags', `ctags', `b2m', `emacsclient',
+		`gnuclient', `gnudoit', `gnuattach', and `rcs-checkin'.
+
+`/usr/local/lib/xemacs-VERSION/lisp' holds the Emacs Lisp libraries;
+		`VERSION' stands for the number of the XEmacs version
+		you are installing, like `18.59' or `19.14'.  Since
+		the lisp libraries change from one version of XEmacs to
+		another, including the version number in the path
+		allows you to have several versions of XEmacs installed
+		at the same time; this means that you don't have to
+		make XEmacs unavailable while installing a new version.
+
+		XEmacs searches for its lisp files in these
+		directories, and then in
+		`/usr/local/lib/xemacs/site-lisp/*'.
+
+`/usr/local/lib/xemacs-VERSION/etc' holds the XEmacs tutorial, the
+		`yow' database, and other architecture-independent
+		files XEmacs might need while running.  VERSION is as
+		specified for `.../lisp'.
+
+`/usr/local/lib/xemacs/lock' contains files indicating who is
+		editing what, so XEmacs can detect editing clashes
+		between users.
+
+`/usr/local/lib/xemacs-VERSION/CONFIGURATION-NAME' contains executable
+		programs used by XEmacs that users are not expected to
+		run themselves, and the DOC file. `VERSION' is the
+		number of the XEmacs version you are installing, and
+		`CONFIGURATION-NAME' is the argument you gave to the
+		`configure' program to identify the architecture and
+		operating system of your machine, like
+		`mips-dec-ultrix' or `sparc-sun-sunos'.  Since these
+		files are specific to the version of XEmacs, operating
+		system, and architecture in use, including the
+		configuration name in the path allows you to have
+		several versions of XEmacs for any mix of machines and
+		operating systems installed at the same time; this is
+		useful for sites at which different kinds of machines
+		share the file system XEmacs is installed on.
+
+`/usr/local/lib/xemacs-VERSION/info' holds the on-line documentation
+		for XEmacs, known as "info files".
+
+`/usr/local/man/man1' holds the man pages for the programs installed
+		in `/usr/local/bin'.
+
+If these directories are not what you want, you can specify where to
+install XEmacs's libraries and data files or where XEmacs should search
+for its lisp files by giving values for `make' variables as part of
+the command.  See the section below called `MAKE VARIABLES' for more
+information on this.
+
+8) If your system uses lock files to interlock access to mailer inbox files,
+then you might need to make the movemail program setuid or setgid
+to enable it to write the lock files.  We believe this is safe.
+The setuid/setgid bits need not be set on any other XEmacs-related
+executables.
+
+9) You are done!  You can remove executables and object files from
+the build directory by typing `make clean'.  To also remove the files
+that `configure' created (so you can compile XEmacs for a different
+configuration), type `make distclean'.
+
+
+MAKE VARIABLES
+
+You can change where the build process installs XEmacs and its data
+files by specifying values for `make' variables as part of the `make'
+command line.  For example, if you type
+
+    make install bindir=/usr/local/gnubin
+
+the `bindir=/usr/local/gnubin' argument indicates that the XEmacs
+executable files should go in `/usr/local/gnubin', not
+`/usr/local/bin'.
+
+Here is a complete list of the variables you may want to set.
+
+`bindir' indicates where to put executable programs that users can
+	run.  This defaults to /usr/local/bin.
+
+`datadir' indicates where to put the architecture-independent
+	read-only data files that XEmacs refers to while it runs; it
+	defaults to /usr/local/lib.  We create the following
+	subdirectories under `datadir':
+	- `xemacs-VERSION/lisp', containing the XEmacs lisp libraries, and
+
+	- `xemacs-VERSION/etc', containing the XEmacs tutorial and the
+		`yow' database.
+	`VERSION' is the number of the XEmacs version you are installing,
+	like `18.59' or `19.14'.  Since these files vary from one version
+	of XEmacs to another, including the version number in the path
+	allows you to have several versions of XEmacs installed at the
+	same time; this means that you don't have to make XEmacs
+	unavailable while installing a new version.
+
+`statedir' indicates where to put architecture-independent data files
+	that XEmacs modifies while it runs; it defaults to
+	/usr/local/lib as well.  We create the following
+	subdirectories under `statedir':
+	- `xemacs/lock', containing files indicating who is editing
+		what, so XEmacs can detect editing clashes between
+		users.
+
+`libdir' indicates where to put architecture-specific data files that
+	XEmacs refers to as it runs; it too defaults to `/usr/local/lib'.
+	We create the following subdirectories under `libdir':
+	- `xemacs-VERSION/CONFIGURATION-NAME', containing executable
+		programs used by XEmacs that users are not expected to run
+		themselves and the DOC file.
+	`VERSION' is the number of the XEmacs version you are installing,
+	and `CONFIGURATION-NAME' is the argument you gave to the
+	`configure' program to identify the architecture and operating
+	system of your machine, like `mips-dec-ultrix' or
+	`sparc-sun-sunos'.  Since these files are specific to the version
+	of XEmacs, operating system, and architecture in use, including
+	the configuration name in the path allows you to have several
+	versions of XEmacs for any mix of machines and operating systems
+	installed at the same time; this is useful for sites at which
+	different kinds of machines share the file system XEmacs is
+	installed on.
+
+`infodir' indicates where to put the info files distributed with
+	XEmacs; it defaults to `/usr/local/lib/xemacs-VERSION/info'.
+
+`mandir' indicates where to put the man pages for XEmacs and its
+	utilities (like `etags'); it defaults to
+	`/usr/local/man/man1'.
+
+`prefix' doesn't give a path for any specific part of XEmacs; instead,
+	its value is used to determine the defaults for all the
+	architecture-independent path variables - `datadir',
+	`statedir', `infodir', and `mandir'.  Its default value is
+	`/usr/local'; the other variables add on `lib' or `man' to it
+	by default.
+
+	For example, suppose your site generally places GNU software
+	under `/usr/users/software/gnusoft' instead of `/usr/local'.
+	By including
+	    `prefix=/usr/users/software/gnusoft'
+	in the arguments to `make', you can instruct the build process
+	to place all of the XEmacs data files in the appropriate
+	directories under that path.
+
+`exec_prefix' serves the same purpose as `prefix', but instead
+	determines the default values for the architecture-dependent
+	path variables - `bindir' and `libdir'.
+
+The above variables serve analogous purposes in the makefiles for all
+GNU software; here are some variables specific to XEmacs.
+
+`lispdir' indicates where XEmacs installs and expects its lisp
+	libraries.  Its default value, based on `datadir' (see above),
+	is `/usr/local/lib/xemacs-VERSION/lisp' (where `VERSION' is as
+	described above).
+
+`sitelispdir' indicates where XEmacs should search for lisp libraries
+	specific to your site. XEmacs checks them in order before
+	checking `lispdir'.  Its default value, based on `datadir'
+	(see above), is `/usr/local/lib/xemacs/site-lisp'.
+
+`etcdir' indicates where XEmacs should install and expect the rest of
+	its architecture-independent data, like the tutorial and yow
+	database.  Its default value, based on `datadir'
+	(see above), is `/usr/local/lib/xemacs-VERSION/etc' (where
+	`VERSION' is as described above).
+
+`lockdir' indicates the directory where XEmacs keeps track of its
+	locking information.  Its default value, based on `statedir'
+	(see above), is `/usr/local/lib/xemacs/lock'.
+
+`archlibdir' indicates where XEmacs installs and expects the
+	executable files and other architecture-dependent data it uses
+	while running.  Its default value, based on `libdir' (see
+	above), is `/usr/local/lib/xemacs-VERSION/CONFIGURATION-NAME'
+	(where VERSION and CONFIGURATION-NAME are as described above).
+
+Remember that you must specify any variable values you need each time
+you run `make' in the top directory.  If you run `make' once to build
+xemacs, test it, and then run `make' again to install the files, you
+must provide the same variable settings each time.  To make the
+settings persist, you can edit them into the `Makefile' in the top
+directory, but be aware that running the `configure' program erases
+`Makefile' and rebuilds it from `Makefile.in'.
+
+The top-level Makefile stores the variable settings it used in the
+Makefiles for the subdirectories, so you don't have to specify them
+when running make in the subdirectories.
+
+
+CONFIGURATION BY HAND
+
+Instead of running the `configure' program, you have to perform the
+following steps.
+
+1) Copy `./src/config.h.in' to `./src/config.h'.
+
+2) Consult `./etc/MACHINES' to see what configuration name you should
+use for your system.  Look at the code of the `configure' script to
+see which operating system and architecture description files from
+`src/s' and `src/m' should be used for that configuration name.  Edit
+`src/config.h', and change the two `#include' directives to include
+the appropriate system and architecture description files.
+
+2) Edit `./src/config.h' to set the right options for your system.  If
+you need to override any of the definitions in the s/*.h and m/*.h
+files for your system and machine, do so by editing config.h, not by
+changing the s/*.h and m/*.h files.  Occasionally you may need to
+redefine parameters used in `./lib-src/movemail.c'.
+
+3) If you're going to use the make utility to build XEmacs, you will
+still need to run `configure' first, giving the appropriate values for
+the variables in the sections entitled "Things `configure' Might Edit"
+and "Where To Install Things."  Note that you may only need to change
+the variables `prefix' and `exec_prefix', since the rest of the
+variables have reasonable defaults based on them.  For each Makefile
+variable of this type, there is a corresponding configure option; for
+example, to change the location of the lock directory, you might use
+
+	 ./configure --lockdir=/nfs/xemacslock
+
+The `configure' script is built from `configure.in' by the `autoconf'
+program.  However, since XEmacs has configuration requirements that
+autoconf can't meet, `configure.in' uses an marriage of custom-baked
+configuration code and autoconf macros.  New versions of autoconf
+could very well break this arrangement, so it may be wise to avoid
+rebuilding `configure' from `configure.in' when possible.
+
+
+BUILDING XEMACS BY HAND
+
+Once XEmacs is configured, running `make' in the top directory performs
+the following steps.
+
+1) Run `make src/paths.h' in the top directory.  This produces
+`./src/paths.h' from the template file `./src/paths.h.in', changing
+the paths to the values specified in `./Makefile'.
+
+2) Cd to `./lib-src' and run `make'.  This creates executables named
+`ctags' and `etags' and `wakeup' and `make-docfile' and `digest-doc'
+and `test-distrib'.  And others.
+
+3) Cd to `./src' and Run `make'.  This refers to files in the `./lisp'
+and `./lib-src' subdirectories using names `../lisp' and
+`../lib-src'.
+
+This creates a file `./src/xemacs' which is the runnable XEmacs,
+assigning it a new build version number by incrementing the build
+version stored in `./lisp/version.el'.
+
+It also creates a file in `./lib-src' whose name is `DOC' followed by
+the current XEmacs version.  This file contains documentation strings
+for all the functions in XEmacs.  Each time you run make to make a new
+xemacs, a new DOC file with a new name is made.  You must keep the DOC
+file for an XEmacs version as long as you keep using that XEmacs
+version.
+
+
+INSTALLATION BY HAND
+
+The steps below are done by running `make install' in the main
+directory of the XEmacs distribution.
+
+1) Copy `./lisp' and its subdirectories, `./etc', and the executables
+in `./lib-src' to their final destinations, as selected in `./src/paths.h'.
+
+Strictly speaking, not all of the executables in `./lib-src' need be copied.
+- The programs `cvtmail', `emacsserver', `env', `fakemail', `hexl',
+    `movemail', `timer', `vcdiff', `wakeup', and `yow' are used by
+    XEmacs; they do need to be copied.
+- The programs `etags', `ctags', `emacsclient', `b2m', `rcs2log',
+    `gnuclient', `gnudoit', and `gnuattach' are intended to be run
+    by users; they are handled below.
+- The programs `make-docfile' and `test-distrib' were
+    used in building XEmacs, and are not needed any more.
+- The programs `digest-doc' and `sorted-doc' convert a `DOC' file into
+    a file for users to read.  There is no important reason to move them.
+
+2) Copy the files in `./info' to the place specified in
+`./lisp/site-init.el' or `./lisp/paths.el'.  Note that if the
+destination directory already contains a file named `dir', you
+probably don't want to replace it with the `dir' file in the XEmacs
+distribution.  Instead, you should make sure that the existing `dir'
+file contains an appropriate menu entry for the XEmacs info.
+
+3) Create a directory for XEmacs to use for clash detection, named as
+indicated by the PATH_LOCK macro in `./src/paths.h'.
+
+4) Copy `./src/xemacs' to `/usr/local/bin', or to some other directory
+in users' search paths.  `./src/xemacs' has an alternate name
+`./src/emacs-EMACSVERSION'; you may wish to make a symbolic link named
+`/usr/local/bin/xemacs' pointing to that alternate name, as an easy way
+of installing different versions.
+
+You can delete `./src/temacs'.
+
+5) Copy the programs `b2m', `emacsclient', `ctags', `etags', `rcs2log',
+`gnuclient', `gnudoit', and `gnuattach' from `./lib-src' to
+`/usr/local/bin'.  These programs are intended for users to run.
+
+6) Copy the man pages in `./etc' for xemacs, ctags, etags, and gnuserv
+into the appropriate man directories.
+
+7) The files in the `./src' subdirectory, except for `xemacs', are not
+used by XEmacs once it is built.  The source would be handy for
+debugging.
