Subject:	ANNOUNCE: DJGPP port of GNU gzip-1.3
Reply-To:	djgpp AT delorie DOT com

  This is a port of GNU Gzip 1.3 to MSDOS/DJGPP.
  ==============================================

  The port consists of the usual three packages that can be downloaded
  from simtel.net and mirrors as:

  Gzip 1.3 binary, info and man format documentation:
  http://www.simtel.net/gnudlpage.php?product=/gnu/djgpp/v2gnu/gzip13b.zip&name=gzip13b.zip

  Gzip 1.3 dvi, html and ps format documentation:
  http://www.simtel.net/gnudlpage.php?product=/gnu/djgpp/v2gnu/gzip13d.zip&name=gzip13d.zip

  Gzip 1.3 source:
  http://www.simtel.net/gnudlpage.php?product=/gnu/djgpp/v2gnu/gzip13s.zip&name=gzip13s.zip



  DJGPP specific changes.
  =======================

  This port is completely based on Eli Zaretskii's port of GNU Gzip 1.2.4a
  (aka gzp124a[bds].zip). This means, that all the djgpp specific funtionality
  introduced with gzp124a will also be available in this new port.
  This port is based on the alpha release of GNU Gzip available at:
    <ftp://alpha.gnu.org/gnu/gzip/gzip-1.3.tar.gz>

  All the changes done to the original distribution are documented in the
  diffs file and located together with all the files needed to configure
  the package (config.bat, config.sed and config.site) in the djgpp subdir.
  This is different from previous ports. The old ones used a makefile located
  in the msdos subdir to compile the sources. This makefile is no longer used
  in this port. This port creates its own config.h und makefile through the
  configure shell script. I have neither inspected nor used the makefile.dj
  located in msdos subdir at all. Please, simple do not use it.
  If you want to recompile the package, run the command:
    make
  Install the products running the command:
    make install
  And reconfigure the package, if needed at all, running the command:
    make distclean
    djgpp\config


  This is a recompilation of all new features introduced with gzp124a
  and also available in this port:
  - Gzip now fully supports long file names on those platforms where DJGPP
    can access them. This means, for example, that compressing `foo.tar' on
    Windows 9X will produce `foo.tar.gz', not `foo.tgz'.
    For backward compatibility, Gzip knows about butchered DOS-style
    extensions of compressed files even when long file names are supported.
    For example, if you have `foo.tgz' and you type "gunzip foo.tar", Gzip
    will find the file even on Windows 9X. Short variants of compressed
    extensions are checked *after* the long ones, so Gzip will try to find
    `foo.tar.gz' before `foo.tgz'.
    Long file name support is checked for each file submitted to Gzip, so
    it will treat each one of them in accordance with the properties of the
    file system where that file resides. In other words, you can compress
    files that reside on DOS and Windows file systems within a single Gzip
    command.
  - Gzip will no longer appear to hang when its input comes from the console
    device. Previous ports would hang when the user typed "gzip -f [Enter]".
    This port allows you to either interrupt the program with Ctrl-C (if you
    typed that command by mistake), or type in the input and end it with a ^Z
    (if you really mean to compress the text you type from the keyboard).
    This is done by avoiding to switch the console device to binary mode,
    so any console reads are now done in text mode.
  - The default compressed file extension is now `.gz', not `z'. This is so
    that compressed file names on Windows 9X would have the usual `.gz'
    extension, but it also means that `foo.cc' will now be compressed into
    `foo.cgz' when long file names are not supported.  Use the -N option to
    `gunzip' to restore the original name, if the original file name had
    more than one character in the extension.
  - When restoring original file names, `gunzip' now converts all characters
    that are not allowed in DOS/Windows file names to similar but valid
    characters, and changes the file name if it is reserved by a DOS device
    driver (like `aux.text' or `prn.tar') by prepending an underscore to it.
  - In previous ports, uncompressing files with certain names on Windows 9X
    when numeric tails are disabled would trigger false warnings about file
    name truncation. This is now fixed.
  - Truncation of long file names on plain DOS is somewhat smarter now:
    `gunzip' treats several additional characters (like `-' and `_') as
    part delimiters.
  - Shell scripts `zmore', `zdiff', `zgrep' and others now work on DOS and
    Windows, and are distributed with the binary distribution, as are all
    the man pages supplied with the official GNU sources.
