A rundown of Emacs archive files

The 'etc' subdirectory contains several other files, named in capital
letters, which you might consider looking at when installing GNU
Emacs.

The file 'configure' is a shell script to acclimate Emacs to the
oddities of your processor and operating system.  It creates the file
'Makefile' (a script for the 'make' program), which automates the
process of building and installing Emacs.  See INSTALL for more
detailed information.

The file 'configure.ac' is the input used by the autoconf program to
construct the 'configure' script.

The shell script 'autogen.sh' generates 'configure' and other files by
running the GNU build tools autoconf and automake, which in turn use
GNU m4 and Perl.  If you want to use it, you will need to install
recent versions of these build tools.  This should be needed only if
you edit files like 'configure.ac' that specify Emacs's autobuild
procedure.

The file 'Makefile.in' is a template used by 'configure' to create
'Makefile'.

The file 'make-dist' is a shell script to build a distribution tar
file from the current Emacs tree, containing only those files
appropriate for distribution.  If you make extensive changes to Emacs,
this script will help you distribute your version to others.

There are several subdirectories:

'src'       holds the C code for Emacs (the Emacs Lisp interpreter and
            its primitives, the redisplay code, and some basic editing
            functions).
'lisp'      holds the Emacs Lisp code for Emacs (most everything else).
'leim'      holds the original source files for the generated files
            in lisp/leim.  These form the library of Emacs input methods,
            required to type international characters that can't be
            directly produced by your keyboard.
'lib'       holds source code for libraries used by Emacs and its utilities
'lib-src'   holds the source code for some utility programs for use by or
            with Emacs, like movemail and etags.
'etc'       holds miscellaneous architecture-independent data files Emacs
            uses, like the tutorial text and tool bar images.
            The contents of the 'lisp', 'leim', 'info', and 'doc'
            subdirectories are architecture-independent too.
'info'      holds the Info documentation tree for Emacs.
'doc/emacs' holds the source code for the Emacs Manual.  If you modify the
            manual sources, you will need the 'makeinfo' program to produce
            an updated manual.  'makeinfo' is part of the GNU Texinfo
            package; you need a suitably recent version of Texinfo.
'doc/lispref'   holds the source code for the Emacs Lisp reference manual.
'doc/lispintro' holds the source code for the Introduction to Programming
                in Emacs Lisp manual.
'msdos'     holds configuration files for compiling Emacs under MS-DOS.
'nextstep'  holds instructions and some other files for compiling the
            Nextstep port of Emacs, for GNUstep and Mac OS X Cocoa.
'nt'        holds various command files and documentation files that pertain
            to building and running Emacs on Windows 9X/ME/NT/2000/XP.
'test'      holds tests for various aspects of Emacs's functionality.
