-                      Precompiled Distributions of
-                           Emacs for Windows
-
-                            Version 24.3
-
-                           March 18, 2013
-
-  This directory contains precompiled distributions for GNU Emacs on
-  Windows (versions before Windows 95 and NT4 are not supported).
-  This port is a part of the standard GNU Emacs distribution from the
-  Free Software Foundation; the precompiled distributions are provided
-  here for convenience since the majority of Windows users are not
-  accustomed to compiling programs themselves.  Corresponding source
-  can be found in the parent directory in emacs-24.3.tar.gz.
-
-* IMPORTANT LEGAL REMINDER
-
-  If you want to redistribute any of the precompiled distributions of
-  Emacs, be careful to check the implications of the GPL.  For instance,
-  if you put the emacs-24.3-bin-i386.zip file from this directory on
-  an Internet site, you must arrange to distribute the source files of
-  the SAME version (i.e. ../emacs-24.3.tar.gz).
-
-  Making a link to our copy of the source is NOT sufficient, since we
-  might upgrade to a new version while you are still distributing the
-  old binaries.
-
-
-* Files in this directory
-
-  + emacs-24.3-bin-i386.zip
-    Windows binaries of Emacs-24.3, with all lisp code and documentation
-    included.
-
-    Download this file if you want a single installation package, and
-    are not interested in the C source code for Emacs. After
-    unpacking, you can optionally run the file bin/addpm.exe to have
-    Emacs add icons to the Start Menu.
-
-    If you need the C source code at a later date, it will be safe to
-    unpack the source distribution on top of this installation.
-
-  + libXpm-3.5.8-w32-src.zip
-    Source code required to compile libXpm-3.5.8 on Windows. Contains
-    a basic Makefile for compiling with mingw32 and a .def file for
-    generating a DLL with the appropriate exports in addition to the
-    source code to provide the subset of functionality Emacs uses from
-    libXpm. This corresponds to the libXpm.dll in emacs-24.3-bin-i386.zip.
-
-* Prerequisites for running Emacs on Windows 9X
-
-  Using Emacs in GUI mode on Windows 95/98/Me requires the UNICOWS.DLL
-  dynamic library, which provides MSLU, the Microsoft Unicode Layer
-  for Windows 9X.  You can freely download it from the Microsoft site.
-
-* Image support
-
-  Emacs 24.3 contains support for images, however for most image
-  formats supporting libraries are required.  This distribution has
-  been tested with the libraries that are distributed with GTK for
-  Windows (http://www.gtk.org/download/win32.php), and the libraries
-  found at http://gnuwin32.sourceforge.net/. The following image
-  formats are supported:
-
-      PBM/PGM/PPM: Supported natively by Emacs. This format is used for
-      the black and white versions of the toolbar icons.
-
-      XPM: a Windows port of the XPM library corresponding to the x.org
-      release of X11R7.3 is included with the binary distribution, but
-      can be replaced by other versions with the name xpm4.dll,
-      libxpm-nox4.dll or libxpm.dll.
-
-      PNG: requires the PNG reference library 1.4 or later, which will
-      be named libpng14.dll or libpng14-14.dll.  LibPNG requires zlib,
-      which should come from the same source as you got libpng.
-      Starting with Emacs 23.3, the precompiled Emacs binaries are
-      built with libpng 1.4.x and later, and are incompatible with
-      earlier versions of libpng DLLs.  So if you have libpng 1.2.x,
-      the PNG support will not work, and you will have to download
-      newer versions.
-
-      JPEG: requires the Independent JPEG Group's libjpeg 6b or later,
-      which will be called jpeg62.dll, libjpeg.dll, jpeg-62.dll or jpeg.dll.
-
-      TIFF: requires libTIFF 3.0 or later, which will be called libtiff3.dll
-      or libtiff.dll.
-
-      GIF: requires libungif or giflib 4.1 or later, which will be
-      called giflib4.dll, libungif4.dll or libungif.dll.
-
-      SVG: not compiled into the binary release, but available if you
-      compile Emacs yourself if you have development packages for all the
-      dependencies. Requires many libraries from GTK and Gnome
-      as well as the base librsvg library. Known to crash Emacs on many
-      sample images.
-
-* XML support
-
-  In order to support XML via libxml2 at runtime, a libxml2-enabled
-  Emacs must be able to find the relevant DLLs during startup; failure
-  to do so is not an error, but libxml2 features won't be available to
-  the running session.
-
-  You can get pre-built binaries (including any required DLL and the
-  header files) at http://sourceforge.net/projects/ezwinports/files/.
-
-* Distributions in .tar.gz and .zip format
-
-  Emacs is distributed primarily as source code in a large gzipped tar
-  file (*.tar.gz).  Because Emacs is quite large and therefore
-  difficult to download over unreliable connections, the Windows
-  binaries are provided in two combinations. The complete lisp source
-  plus executables (bin), and executables only (barebin) for unpacking
-  over the top of the source distribution.  Formerly, we used the same
-  .tar.gz format but since there are no longer legal problems with
-  .zip files, and the latest versions of Windows support these
-  natively, the Windows binaries of Emacs are now distributed as .zip
-  files.
-
-* Distributions for non-x86 platforms
-
-  Distributions for non-x86 platforms are no longer supplied. Older
-  platforms supported by Windows NT no longer seem to be in demand,
-  and Emacs is yet to be ported to 64 bit Windows platforms. If you
-  are willing to help port Emacs 24 to 64 bit versions of Windows,
-  your contribution will be welcome on the emacs-devel mailing list.
-
-* Unpacking distributions
-
-  Ports of GNU gzip and GNU tar for handling the source distribution file
-  format can be found in several places that distribute ports of GNU
-  programs, for example:
-
-    Cygwin:   http://www.cygwin.com/
-    GnuWin32: http://gnuwin32.sourceforge.net/
-
-  Many other popular file compression utilities for Windows are also
-  able to handle gzipped tar files. 7zip is one free Windows graphical
-  program that is able to handle many archive formats.
-
-  Open a command prompt (MSDOS) window.  Decide on a directory in which
-  to place Emacs.  Move the distribution to that directory, and then
-  unpack it as follows.
-
-  If you have the gzipped tar version, use gunzip to uncompress the tar
-  file on the fly, and pipe the output through tar with the "xvf" flags
-  to extract the files from the tar file:
-
-    % gunzip -c some.tar.gz | tar xvf -
-
-  You may see messages from tar about not being able to change the
-  modification time on directories, and from gunzip complaining about a
-  broken pipe.  These messages are harmless and you can ignore them.  On
-  Windows NT, unpacking tarballs this way leaves them in compressed
-  form, taking up less space on disk.  Unfortunately, on Windows 95 and
-  98, a large temporary file is created, so it is better to use the
-  djtarnt.exe program, which performs the equivalent operation in one
-  step:
-
-    % djtarnt -x some.tar.gz
-
-  You may be prompted to rename or overwrite directories when using
-  djtarnt: simply type return to continue (this is harmless).
-
-  Zip files can be unpacked using unzip.exe from info-zip.org
-  if you do not already have other tools to do this.
-
-    % unzip some.zip
-
-  The precompiled binaries can be unpacked using unzip.exe from info-zip.org
-  if you do not already have other tools to do this.
-
-    % unzip some.zip
-
-  Once you have unpacked a precompiled distribution of Emacs, it should
-  have the following subdirectories:
-
-        bin     etc     info    lisp    site-lisp
-
-
-* Unpacking with other tools
-
-  If you do use other utility programs to unpack the distribution, check
-  the following to be sure the distribution was not corrupted:
-
-  + Be sure to disable the CR/LF translation or the executables will
-    be unusable.  Older versions of WinZip would enable this
-    translation by default when unpacking .tar files.  If you are
-    using WinZip, disable it.  (I don't have WinZip myself, and I do
-    not know the specific commands necessary to disable it.)
-
-  + Check that filenames were not truncated to 8.3.  For example, there
-    should be a file lisp/abbrevlist.el; if this has been truncated to
-    abbrevli.el, your distribution has been corrupted while unpacking
-    and Emacs will not start.
-
-  + Check that filenames were not changed by your web-browser.  Some
-    proprietary web-browsers save .tar.gz files as .tar.tar. You might
-    like to consider switching to a Free modern browser if your browser
-    has this bug.
-
-  + I've also had reports that some older "gnuwin32" port of tar
-    corrupts the executables.  Use the latest version from the gnuwin32
-    site or another port of tar instead.
-
-  If you believe you have unpacked the distributions correctly and are
-  still encountering problems, see the section on Further Information
-  below.
-
-
-* Compiling from source
-
-  If you would like to compile Emacs from source, download the source
-  distribution, unpack it in the same manner as a precompiled
-  distribution, and look in the file nt/INSTALL for detailed
-  directions.  It is recommended to use GCC 2.95 or later with MinGW
-  support to compile the source.  The port of GCC included in Cygwin
-  is supported, but check the nt/INSTALL file if you have trouble
-  since some builds of GNU make aren't supported.
-
-
-* Further information
-
-  The Emacs on MS Windows FAQ is distributed with Emacs (info
-  manual "efaq-w32"), and at
-
-        https://www.gnu.org/software/emacs/manual/efaq-w32.html
-
-  In addition to the FAQ, there is a mailing list for discussing issues
-  related to the Windows port of Emacs.  For information about the
-  list, see this Web page:
-
-        https://lists.gnu.org/mailman/listinfo/help-emacs-windows
-
-  To ask questions on the mailing list, send email to
-  help-emacs-windows@gnu.org.  (You don't need to subscribe for that.)
-  To subscribe to the list or unsubscribe from it, fill the form you
-  find at https://mail.gnu.org/mailman/listinfo/help-emacs-windows as
-  explained there.
-
-  Another valuable source of information and help which should not be
-  overlooked is the various Usenet news groups dedicated to Emacs.
-  These are particularly good for help with general issues which aren't
-  specific to the Windows port of Emacs.  The main news groups to use
-  for seeking help are:
-
-        gnu.emacs.help
-        comp.emacs
-
-  There are also fairly regular postings and announcements of new or
-  updated Emacs packages on this group:
-
-        gnu.emacs.sources
-
-  Enjoy!
