   or can be selected using the menu.

============
Installation
============
Create three 1.44M floppies containing the following files, or
put them all in the same directory on your hard disk.

Disk 1:
  For Win32, unzip gsv23w32.zip
      README.TXT    (this file)
      LICENCE
      FILE_ID.DIZ
      README32.TXT
      win32.zip
      setup.exe     Installation program
      setp32de.dll  German language resources
      setp32fr.dll  French language resources
      wizunz32.dll  Info-ZIP unzip utility

  For Win16, unzip gsv23w16.zip
      README.TXT   (this file)
      LICENCE
      FILE_ID.DIZ
      README16.TXT
      win16.zip
      setup16.exe   Installation program
      setp16de.dll  German language resources
      setp16fr.dll  French language resources
      wizunz16.dll  Info-ZIP unzip utility

  For OS/2, unzip gsv23os2.zip
      README.TXT    (this file)
      LICENCE
      FILE_ID.DIZ
      README2.TXT
      os2.zip
      os2setup.exe  Installation program
      setup2de.dll  German language resources
      setup2fr.dll  French language resources
      unzip2.dll    Info-ZIP unzip utility

Disk 2:
  gs503ini.zip      Aladdin Ghostscript library files
    PLUS
  gs503w32.zip      MS-Windows Win32 Aladdin Ghostscript
     OR 
  gs503os2.zip      OS/2 Aladdin Ghostscript

  (for Windows 3.1/Win16 use gs403ini.zip plus gs403win.zip)

Disk 3:
  gs503fn1.zip      Aladdin Ghostscript fonts.

Disk 1 is the contents of gsv23w32.zip or gsv23w16.zip or gsv23os2.zip
(all of which are contained in gsview23.zip).
Disks 2 and 3 are obtained from ftp://ftp.cs.wisc.edu/ghost/aladdin/

If using the floppy install method, 10 Mbytes of hard disk space is 
required.

The installation will overwrite any version of GSview or
Aladdin Ghostscript in the destination directories.  If you
wish to save your Fontmap file, back it up to another directory.
Make sure that the zip files are transferred in binary mode and
are all present.

To install from OS/2, run 'os2setup.exe' from disk 1.
If you do not already have EMX isntalled on your system, you will 
also need a Disk 4:
  emxrt.zip         EMX Run Time library (OS/2 only).
from ftp://ftp.cdrom.com/pub/os2/emx09c/emxrt.zip
or   ftp://ftp-os2.nmsu.edu/pub/os2/dev/emx/v0.9c/emxrt.zip

For Windows NT or Windows 95, run 'setup.exe' from disk 1.
If you get a "Can't open DDE connection to Program Manager"
message, your system is corrupted.  Reboot Windows then try again.

For MS-Windows 3.1, it is recommended that you use the
Win32 version.  You must have Win32s installed before
installing GSview.  See http://www.microsoft.com/ or
  ftp://ftp.microsoft.com/softlib/mslfiles/PW1118.EXE
GSview and Ghostscript will not work with some versions
of Win32s.  If it doesn't work with your version, try 
updating to a later version of Win32s.  Some computers
will work with Win32s v1.15, others will not.
To install from MS-Windows, run 'setup.exe' from disk 1.
If you wish to use the slower 16-bit version, install
using 'setup16.exe' from gsv23w16.zip.

If you don't like automatic installation programs, it is 
possible to install GSview and Ghostscript manually.  See
the Setup topic below for more details.

If you wish to use install GSview without any prompts, give
a destination directory on the command line.  For example:
  setup c:\gstools
This will not prompt for a destination directory and will
overwrite files without asking.

Configuration of GSview will occur the first time it is run.

===========
Compilation
===========
To compile GSview for OS/2 you need IBM NMAKE.EXE and EMX/GCC 0.9c.
To create the GSview online help you need the IBM toolkit.
Copy gvpm.mak to Makefile and edit COMPBASE and EMXPATH as required.
Type 'nmake'

To compile GSview for Windows you need Borland C++ 4.5.
Copy gvwin.mak to Makefile then edit COMPBASE as required.
Type 'make'.

=====
Setup
=====
These are the manual setup instructions.
It is recommended that you use the installation program
as described in the Installation section above.

Create the directories gsview and gsN.NN (where N.NN is the
Ghostscript version number).

Copy 
  gvpm.exe, gvpgs.exe, gvpmen.dll, gvpmde.dll, gvpmfr.dll,
  gvpmen.hlp, gvpmde.hlp and gvpmfr.hlp (OS/2)
     and/or
  gsview32.exe, gvwgs32.exe, gsv16spl.exe, 
  gsvw32en.dll, gsvw32de.dll, gsvw32fr.dll
  gsviewen.hlp, gsviewde.hlp and gsviewen.hlp (MS-Windows)
    and 
  printer.ini
to the GSview directory.  
Unzip Ghostscript into the gsN.NN directory and the Ghostscript
fonts into gsN.NN\fonts.

Start GSview and follow the configuration wizard instructions.

GSview (gvpm.exe) will run under OS/2 2.1 and OS/2 Warp. 
It may run under OS/2 2.0.
PM GSview has been compiled with EMX/GCC 0.9c and requires
the emx 0.9c DLL's.  These are available from
  ftp://ftp.cdrom.com/pub/os2/emx09c/emxrt.zip
  ftp://ftp-os2.nmsu.edu/pub/os2/dev/emx/v0.9c/emxrt.zip

GSview (gsview32.exe) will run under Windows NT, Windows 95 and
Windows 3.1/Win32s.  It will not run under Windows 3.0.

See the on-line help for more details.
The 'Common Problems' topic is worth reading if GSview won't work.

GSview uses Ghostscript to display the contents of the PostScript
files.  Ghostscript is a separate program from GSview; it is
written and owned by Aladdin Enterprises, not by Russell Lang.

Aladdin Ghostscript comes with a licence that is more restrictive than 
the GNU Licence; in particular, it restricts the distribution of
Aladdin Ghostscript in commercial contexts.  Please see the file PUBLIC
that accompanies Aladdin Ghostscript for more details.  

GSview uses pstotext in an external DLL. pstotext was written by 
Andrew Birrell and Paul McJones.  It is
  Copyright (C) 1995-1996, Digital Equipment Corporation.
See the licence in pstotext.txt or pstotext.zip for more details.
If you do not agree to the pstotext licence, delete pstotext.zip,
pstotxt2.dll and pstotxt3.dll.

GSview uses zlib 1.0.4 in an external DLL.  zlib is
  Copyright (C) 1995-1996 Jean-loup Gailly and Mark Adler.
  See http://www.cdrom.com/pub/infozip/zlib/

The installation programs use an unzip decompression library (DLL)
by the Info-ZIP group.  The original sources are freely available
from ftp://ftp.cdrom.com/pub/infozip/ on the Internet.
