GSview is available from
	http://www.cs.wisc.edu/~ghost/gsview/
For technical information on GSview for Windows or PM GSview, please contact
Russell Lang ([e-mail]).  (Aladdin provides Lang with a mail alias,
but Lang is not an employee or agent of Aladdin.)  These programs are also
available for commercial licensing from Artifex Software Inc.

Users have created two packages that provide a set of GSview-like commands
that MS-DOS users can enter through the keyboard.  One is available from
	ftp.pg.gda.pl:/pub/TeX/GUST/contrib/PS/PS_VIEW/ps_view.ps
and is in the public domain.  The other is available from
	puccini.ujf-grenoble.fr:pub/contrib-ps/DOS-PSV/*
and appears to be redistributable with no restrictions.

Another user has created a Ghostscript-based bitmap previewing program for
Linux that doesn't use X Windows, called BMV.

  BMV is a very simple viewer of images in the pbm(5)-raw format
      and front end for GhostScript, based on Svgalib library for Linux

  BMV is distributed under GNU GPL (General Public License),
    you can obtain a copy from many FTP sites if you are interested in details

  Jan Kybic, Prosecka 681, Praha 9, Czech Republic, <[e-mail]>

  There is a port of BMV under SCO Unix by William Bader
  <[e-mail]>. Contact him if you are interested.

BMV is available from
	ftp://sunsite.unc.edu/pub/Linux/apps/graphics/viewers/bmv-1.1.tar.gz

Mr. Norio Katayama ([e-mail]) has done some work on making
Ghostscript work well with Kanji fonts.  Please contact him for more
information.

An extensive list of Unix systems and the fonts available on them is
available on

Genscript is a free replacement for the enscript program.  Genscript
converts ASCII files to PostScript and spools generated PostScript output to
the specified printer or leaves it to file.  Genscript can be easily
extended to handle different output media and it has many options which can
be used to customize printouts.  You can find the current version on

  ftp://prep.ai.mit.edu/pub/gnu/genscript-1.3.0.tar.gz

			(or http://www.hut.fi/~mtr/genscript/)

There is a good free utility "pstotext" that works with Ghostscript to
extract plain-text from PostScript files.  It is much better than the
ps2ascii utility distributed with Ghostscript.  You can read the pstotext
documentation at:

    http://www.research.digital.com/SRC/virtualpaper/manpages/pstotext.1.html

You can download pstotext from the following URL (after reading and agreeing
to the license offered there):

    http://www.research.digital.com/SRC/virtualpaper/pstotext.html

There is no formal technical support for pstotext, but the authors are happy
to receive your questions and comments by e-mail at the following locations:

There is a Frequently Asked Questions file available for Internet anonymous
FTP from
	ftp://ftp.cs.wisc.edu/ghost/gsfaq.txt
(i.e., FTP to ftp.cs.wisc.edu, file name /ghost/gsfaq.txt)
or, if you run AFS, by direct reference to
	/afs/cs.wisc.edu/public/ghost/gsfaq.txt
and also available by HTTP (World Wide Web) from
	http://www.cs.wisc.edu/~ghost/gsfaq.html
It isn't updated very often, so it may be a little out of date.

In December 1995, CompuServe announced that the Graphics Support Forum
offers Message Section and Library 21, "Ghostscript", for technical
assistance with Ghostscript.  Ghostscript is available for downloading in
Library 21, "Ghostscript." To access the Graphics Support Forum, GO
GRAPHSUP.  This service has no connection with Aladdin Enterprises.

Aladdin Enterprises doesn't have the resources to respond to questions from
users of the freely available versions of Ghostscript.  (Responding to
questions and bug reports is one of the benefits that Artifex Software
provides to commercial users in exchange for the licensing fee.)  If you
have problems with Ghostscript, and you have access to the Internet, we
suggest you post your question to one of the following Usenet newsgroups:

	- If your question is about GNU Ghostscript (currently, versions
3.33 and below), post it to the gnu.ghostscript.bug newsgroup.  If you have
access to Internet mail, but not news, send e-mail to
[e-mail], which is equivalent to posting to the
gnu.ghostscript.bug newsgroup.

	- If your question is about Aladdin Ghostscript (currently, versions
above 3.33), post it to the comp.lang.postscript newsgroup.  If you have
access to Internet mail, but not news, send e-mail to
[e-mail], which is equivalent to posting to the
comp.lang.postscript newsgroup.  (We hope to establish a separate newsgroup
for Aladdin Ghostscript in the future, since comp.lang.postscript was not
intended for Ghostscript discussion per se.)

There are hundreds of Ghostscript user sites all over the world, and often
another user will be able to help you. If you are having trouble with
a specific device driver, look in the file devs.mak and see if it is a
user-maintained driver.  If so, please contact the person listed there
directly; please do not contact Aladdin Enterprises regarding
user-maintained drivers.

Aladdin Enterprises does want Ghostscript to be of high quality, so if you
have been running Ghostscript and encounter a problem, we encourage you to
post bugs to the newsgroups mentioned above.  We will consider investigating
problems reported to those newsgroups, or e-mailed directly to
[e-mail], if (and only if) the report meets all the following
criteria:

	- You are using the most recent version of Aladdin Ghostscript.

	- You obtained Ghostscript directly from Aladdin Enterprises, or
	from the FTP or AFS site on the Internet mentioned above (i.e., not
	from a bulletin board system or a commercial system such as
	CompuServe or GEnie).

	- You have installed Ghostscript successfully, and used it
	successfully on other input data.

	- Your problem is reproducible, and you can mail us the input
	data that evokes it (by e-mail, anonymous FTP, or PC diskette).
	(But please do not send anything unless we ask you for it.)

	- You created the bug report using the form in bug-form.txt,
	completely filled out.

Bug reports that include suggested fixes are especially welcome.

As time permits, Aladdin Enterprises may also respond to e-mail from the
following classes of users:

	- Beta testers who have actually given us at least one report on
	some beta version supplied to them.

	- People developing drivers that are for, or applications that
	are based on, Ghostscript and that will be made freely available.

	- People who express serious interest in commercial licensing
	of Ghostscript.

Aladdin Enterprises owns or has access to the following hardware and
software:

	Pentium and 486 PCs with color SuperVGA displays;
	  Epson-compatible printer (the printer also is compatible with
	  the IBM Proprinter); various H-P printers; Canon BubbleJet.
	  These systems run both MS-DOS 5.0 and 6.22 and Microsoft Windows
	  3.1 with Borland C++ 3.1 (and several older versions), and Linux
	  with gcc.

	SPARCstation, SunOS 4.1, cc and gcc, X11R5 and SunView;
	  both monochrome and color displays.

	DECstation, Ultrix.

	IBM RS/6000 and PowerPC, Unix (AIX 3.n).

	DEC AXP (Alpha), OSF/1.

If your problem turns out to be specific to some other hardware or
software configuration, it may take longer to track down, since we
will have to rely on other users to help.

Aladdin's contact information is as follows:

		Aladdin Enterprises
		P.O. box 60264
		Palo Alto, CA 94306
		phone [phone] (8:30 AM - noon, Pacific time)
		fax [phone]

Please do not contact us if all you want is help with the freely distributed
versions of Ghostscript!  Ghostscript is free, but our time is not.  If you
call for help, we will tell you politely that we cannot answer your
question.  Ghostscript's documentation, while not of commercial end-user
quality, has been adequate for thousands of users (for many of whom English
is a foreign language), so the answer to your question is very likely in it
somewhere.

******** Things you can do to help ********
********

There are some projects that users could do that are somewhat
decoupled from the main body of the code, and that would help improve
Ghostscript:

	- Someone is needed to take responsibility for texinfo and/or man
page documentation for Ghostscript.  What this would involve is updating
this documentation during the beta test period for each release, and
sending it to Aladdin to be included in the final fileset.  (Aladdin would
continue to supply the plain-text documentation as it currently exists.)

	- Adobe has donated the specification of the Display PostScript C
API to the X distribution, as well as the client-side implementation.
Modifying Ghostscript to interface with this code as a substitute for a
Display PostScript server might make Ghostscript a lot more useful, since
it would then be "plug compatible" with Display PostScript in an important
way.  Contact [e-mail] if you would like to help with this.
