BUILDING AND INSTALLATION

(This is for a Unix or Unix-like system.  For Windows NT or Windows
95, see the file README.NT.)

This version requires either Emacs 20.3 or later (but 20.3 is known to
be quite buggy) or XEmacs 20.4 or later.  If you're using a version
without Gnus 5.8 or later, get a more recent distribution from
gnus.org.

1) Make sure your system has enough memory to run Emacs, plus about 1
megabyte to spare.

Building Emacs/W3 requires about 2.8 Mb of disk space (including the
sources).  Once installed, Emacs/W3 occupies about 2 Mb in the file
system where it is installed.

2) To build Emacs/W3, you must configure a few simple items.  Emacs/W3 
uses the GNU 'autoconf' program for meta-configuration.  You should be 
able to run the program `configure' as follows:

   ./configure [--OPTION[=VALUE]] ...

If you wish to build with a specific version of Emacs, specify
`--with-emacs=VARIANT'.  If you wish to build with a specific version
of XEmacs, specify `--with-xemacs=VARIANT'.  If you omit these
options, `configure' will try to figure out what flavor of Emacs to
use.  It will honor the `EMACS' environment variable if it is set,
otherwise it will check for `xemacs' and `emacs' in your path.

If you had to install Gnus in a non-standard place, specify
`--with-gnus=DIR'.  If you omit this option, `configure' will try to
figure out where an acceptable version of Gnus is installed.

If you prefer not to use the GNU `makeinfo' program if it is
available, specify `--with-makeinfo=no'.  This will cause the info
files to be built using Emacs.

The `--prefix=PREFIXDIR' option specifies where the installation process
should put Emacs/W3 and its data files.  This defaults to `/usr/local'.
- Lisp files go in PREFIXDIR/share/emacs/site-lisp
  (unless the `--with-lispdir' option says otherwise).
- The architecture-independent files go in PREFIXDIR/share/emacs/w3
  (unless the `--datadir' option says otherwise).

`configure' doesn't do any compilation or installation itself.  It
just creates the files that influence those things:
`./Makefile', `texi/Makefile', and `lisp/Makefile'.

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'.  `configure'
also creates a file `config.cache' that saves the results of its tests
to make reconfiguring faster, and a file `config.log' containing
compiler output (useful mainly for debugging `configure').  You can
give `configure' the option `--cache-file=FILE' to use the results of
the tests in FILE instead of `config.cache'.  Set FILE to `/dev/null'
to disable caching, for debugging `configure'.

3) Run `make' in the top directory of the Emacs/W3 distribution to
finish building Emacs/W3 in the standard way.  You can "install" the
package with `make install'.  By default, Emacs/W3's files are
installed in the following directories:

`/usr/local/share/emacs/site-lisp' holds the Emacs/W3 lisp code.

`/usr/local/share/emacs/w3' holds any data files for Emacs/W3,
		including `stylesheet' which controls all default
		formatting settings.

`/usr/local/info' holds the on-line documentation for Emacs/W3, known
		as "info files."

4) Check the file `dir' in your site's info directory (usually
/usr/local/info) to make sure that it has a menu entry for the
Emacs/W3 info files.

5) You are done!  You can remove object files from the build directory 
by typing `make clean'.  To also remove the files that `configure'
created (so you can compile Emacs/W3 for a different configuration),
type `make distclean'.
