-Installation on MSDOG (a.k.a. MSDOS)
-
-To install on MSDOG, you need to have the GNU C compiler for MSDOG
-(also known as djgpp), GNU Make, rm, mv, and sed.  See the remarks in
-config.bat for more information about locations and versions.  The
-file etc/FAQ includes pointers to Internet sites where you can find
-the necessary utilities; search for "MS-DOS".  The configuration step
-(see below) will test for these utilities and will refuse to continue
-if any of them isn't found.
-
-Recompiling Lisp files in the `lisp' subdirectory using the various
-targets in the lisp/Makefile file requires additional utilities:
-`find' and `xargs' (from Findutils), `touch' (from Fileutils) GNU
-`echo' and `test' (from Sh-utils), `tr, `sort', and `uniq' (from
-Textutils), and a port of Bash.  However, you should not normally need
-to run lisp/Makefile, as all the Lisp files are distributed in
-byte-compiled form as well.
-
-If you are building the MSDOG version of Emacs on an MSDOG-like system
-which supports long file names (e.g. Windows 9X or Windows XP), you
-need to make sure that long file names are handled consistently both
-when you unpack the distribution and compile it.  If you intend to
-compile with DJGPP v2.0 or later, and long file names support is
-enabled (LFN=y in the environment), you need to unpack Emacs
-distribution in a way that doesn't truncate the original long
-filenames to the DOS 8.3 namespace; the easiest way to do this is to
-use djtar program which comes with DJGPP, since it will note the LFN
-setting and behave accordingly.  DJGPP v1 doesn't support long
-filenames, so you must unpack Emacs with a program that truncates the
-filenames to 8.3 naming as it extracts files; again, using djtar after
-setting LFN=n is the recommended way.  You can build Emacs with LFN=n
-even if you use DJGPP v2, if some of your tools don't support long
-file names: just ensure that LFN is set to `n' during both unpacking
-and compiling.
-
-(By the time you read this, you have already unpacked the Emacs
-distribution, but if the explanations above imply that you should have
-done it differently, it's safer to delete the directory tree created
-by the unpacking program and unpack Emacs again, than to risk running
-into problems during the build process.)
-
-It is important to understand that the runtime support of long file
-names by the Emacs binary is NOT affected by the LFN setting during
-compilation; Emacs compiled with DJGPP v2.0 or later will always
-support long file names on Windows no matter what was the setting
-of LFN at compile time.  However, if you compiled with LFN disabled
-and want to enable LFN support after Emacs was already built, you need
-to make sure that the support files in the lisp, etc and info
-directories are called by their original long names as found in the
-distribution.  You can do this either by renaming the files manually,
-or by extracting them from the original distribution archive with
-djtar after you set LFN=y in the environment.
-
-To unpack Emacs with djtar, type this command:
-
-    djtar -x emacs.tgz
-
-(This assumes that the Emacs distribution is called `emacs.tgz' on
-your system.)
-
-If you want to print international characters, install the intlfonts
-distribution.  For this, create a directory called `fonts' under the
-Emacs top-level directory (usually called `emacs-XX.YY') created by
-unpacking emacs.tgz, chdir into the directory emacs-XX.YY/fonts, and
-type this:
-
-    djtar -x intlfonts.tgz
-
-When unpacking is done, a directory called `emacs-XX.YY' will be
-created, where XX.YY is the Emacs version.  To build and install
-Emacs, chdir to that directory and type these commands:
-
-    config msdos
-    make install
-
-Running "config msdos" checks for several programs that are required
-to configure and build Emacs; if one of those programs is not found,
-CONFIG.BAT stops and prints an error message.  If you have DJGPP
-version 2.0 or 2.01, it will complain about a program called
-DJECHO.EXE.  These old versions of DJGPP shipped that program under
-the name ECHO.EXE, so you can simply copy ECHO.EXE to DJECHO.EXE and
-rerun CONFIG.BAT.  If you have neither ECHO.EXE nor DJECHO.EXE, you
-should be able to find them in your djdevNNN.zip archive (where NNN is
-the DJGPP version number).
-
-On Windows NT, Windows 2000/XP/Vista, running "config msdos" might
-print an error message like "VDM has been already loaded".  This is
-because those systems have a program called `redir.exe' which is
-incompatible with a program by the same name supplied with DJGPP,
-which is used by config.bat.  To resolve this, move the DJGPP's `bin'
-subdirectory to the front of your PATH environment variable.
-
-To install the international fonts, chdir to the intlfonts-X.Y
-directory created when you unpacked the intlfonts distribution (X.Y is
-the version number of the fonts' distribution), and type the following
-command:
-
-    make bdf INSTALLDIR=..
-
-After Make finishes, you may remove the directory intlfonts-X.Y; the
-fonts are installed into the fonts/bdf subdirectory of the top-level
-Emacs directory, and that is where Emacs will look for them by
-default.
-
-Building Emacs creates executable files in the src and lib-src
-directories.  Installing Emacs on MSDOS moves these executables to a
-sibling directory called bin.  For example, if you build in directory
-/emacs, installing moves the executables from /emacs/src and
-/emacs/lib-src to the directory /emacs/bin, so you can then delete the
-subdirectories /emacs/src and /emacs/lib-src if you wish.  The only
-subdirectories you need to keep are bin, lisp, etc and info.  (If you
-installed intlfonts, keep the fonts directory and all its
-subdirectories as well.)  The bin subdirectory should be added to your
-PATH.  The msdos subdirectory includes a PIF and an icon file for
-Emacs which you might find useful if you run Emacs under MS Windows.
-
-Emacs on MSDOS finds the lisp, etc and info directories by looking in
-../lisp, ../etc and ../info, starting from the directory where the
-Emacs executable was run from.  You can override this by setting the
-environment variables EMACSDATA (for the location of `etc' directory),
-EMACSLOADPATH (for the location of `lisp' directory) and INFOPATH (for
-the location of the `info' directory).
-
-MSDOG is a not a multitasking operating system, so Emacs features such
-as asynchronous subprocesses that depend on multitasking will not
-work.  Synchronous subprocesses do work.
-
-Version 2.0 of djgpp has two bugs that affect Emacs.  We've included
-corrected versions of two files from djgpp in the msdos subdirectory:
-is_exec.c and sigaction.c.  To work around the bugs, compile these
-files and link them into temacs.  Djgpp versions 2.01 and later have
-these bugs fixed, so upgrade if you can before building Emacs.
