-
-As mentioned above, Eshell comes preinstalled as of Emacs 21. If you're
-using Emacs 20.4 or later, or XEmacs 21, you can download the most
-recent version of Eshell from
-@url{http://www.gci-net.com/users/j/johnw/Emacs/eshell.tar.gz}.
-
-However, if you are using Emacs 21, you may skip this section.

-
-@section Long Form
-
-@enumerate
-@item
-Before building and installing Eshell, it is important to test that it
-will work properly on your system. To do this, first load the file
-@file{eshell-auto}, which will define certain autoloads required to run
-Eshell. This can be done using the command @kbd{M-x load-file}, and
-then selecting the file @file{eshell-auto.el}.
-
-@item
-In order for Emacs to find Eshell's files, the Eshell directory must be
-added to the @code{load-path} variable. This can be done within Emacs by
-typing:
-
-@example
-ESC : (add-to-list 'load-path "<path where Eshell resides>") RET
-ESC : (add-to-list 'load-path "<path where Pcomplete resides>") RET
-@end example
-
-@item
-Start Eshell from the distributed sources, using default settings, by
-typing @kbd{M-x eshell}.
-
-@item
-Verify that Eshell is functional by typing @command{ls} followed by
-@key{RET}. You should have already seen a version banner announcing the
-version number of this release, followed by a prompt.
-
-@item
-Run the test suite by typing @command{eshell-test} followed by @key{RET}
-in the Eshell buffer. It is important that Emacs be left alone while
-the tests are running, since extraneous command input may cause some of
-the tests to fail (they were never intended to run in the background).
-If all of the tests pass, Eshell should work just fine on your system.
-If any of the tests fail, please send e-mail to the Eshell maintainer
-using the command @kbd{M-x eshell-report-bug}.
-
-@item
-Edit the file @file{Makefile} in the directory containing the Eshell
-sources to reflect the location of certain Emacs directories at your
-site. The only things you really have to change are the definitions of
-@code{lispdir} and @code{infodir}. The elisp files will be copied to
-@code{lispdir}, and the info file to @code{infodir}.
-
-@item
-Type @kbd{make install} in the directory containing the Eshell sources.
-This will byte-compile all of the @file{*.el} files and copy both the
-source and compiled versions to the directories specified in the
-previous step. It will also copy the info file, and add a corresponding
-entry to your @file{dir} file----if the program @code{install-info} can
-be found on your system.
-
-If you only want to create the compiled elisp files, but don't want to
-install them, you can type just @kbd{make} instead.
-
-@item
-Add the directory into which Eshell was installed to your
-@code{load-path} variable. This can be done by adding the following
-line to your @file{.emacs} file:
-
-@example
-(add-to-list 'load-path "/usr/local/share/emacs/site-lisp/eshell")
-@end example
-
-The actual directory on your system may differ.
-
-@item
-To install Eshell privately, edit your @file{.emacs} file; to install
-Eshell site-wide, edit the file @file{site-start.el} in your
-@file{site-lisp} directory (usually
-@file{/usr/local/share/emacs/site-lisp} or something similar). In
-either case enter the following line into the appropriate file:
-
-@example
-(load "eshell-auto")
-@end example
-
-@item
-Restart Emacs. After restarting, customize the variable
-@code{eshell-modules-list}. This variable selects which Eshell
-extension modules you want to use. You will find documentation on each
-of those modules in the Info manual.
-@end enumerate
-
-@cindex documentation, printed version
-@cindex printed version of documentation
-If you have @TeX{} installed at your site, you can make a typeset manual
-from @file{eshell.texi}.
-
-@enumerate
-@item
-Run @TeX{} by typing @kbd{texi2dvi eshell.texi}. (With Emacs 21.1 or
-later, typing @kbd{make eshell.dvi} in the @file{man/} subdirectory of
-the Emacs source distribution will do that.)
-
-@item
-Convert the resulting device independent file @file{eshell.dvi} to a
-form which your printer can output and print it. If you have a
-postscript printer, there is a program, @code{dvi2ps}, which does that; there
-is also a program which comes together with @TeX{}, @code{dvips}, which
-you can use. For other printers, use a suitable DVI driver,
-e.g., @code{dvilj4} for LaserJet-compatible printers.
