Artifex does not offer commercial support as a separate service; support is
available only to OEM licensees (that is, licensees who redistribute
Ghostscript in a product).

<h2><a name="Platforms"></a>What platforms does Ghostscript run on?</h2>

<p>
Ghostscript is written entirely in C (with some optional assembly-language
accelerators for DOS platforms), with special care taken to make it run
properly on systems of either byte order ("low-endian" and "high-endian")
and of various word lengths.  GNU Ghostscript is known to run on the
following platform families:

<ul>
<li>A wide variety of Unix systems using X Windows version 11, releases 4, 5,
and 6, including

<ul compact>
<li>Sun-3, Sun-4, Sun-386i, Sun SPARCStation with SunOS 4 and Solaris 2.[56]
<li>Generic Intel-based systems running Linux, 386/ix, 386BSD, FreeBSD, ISC Unix, SCO Unix, and Solaris
<li>H-P 9000/300 and 9000/800
<li>DECStation 2100, 3100, and 5xxx
<li>Alpha systems running Digital Unix
<li>VAX running Ultrix
<li>Sequent Symmetry
<li>Convex C1 and C2
<li>Tektronix 4300
<li>SGI Iris Indigo
<li>4.4BSD Unix systems (FreeBSD on Intel)
<li>NetBSD on Intel, Sun SPARC, Motorola M68K (Apple, Amiga, Sun, H-P), and VAX
</ul>

<li>Sun workstations running SunView

<li>VAX and Alpha systems running OpenVMS with X11 compiled with
either DEC C or gcc
</ul>

<p>
Aladdin Ghostscript is known to run on all of the above, and additionally
on the following platform families:

<ul>
<li>IBM PC and compatibles with EGA, VGA, SuperVGA, or compatible graphics under MS-DOS 3.1, 3.3, 5.0, or 6.22, and Microsoft Windows 3.1, NT, 95, or 98;

<li>IBM PC and compatibles under DR DOS 6.0;

<li>IBM PC and compatibles under OS/2 2.0, 2.1 and Warp 3.0.

<li>Apple Macintosh with System 7 or later, both Motorola 680x0 and PowerPC
native. For specific information on the Macintosh implementation, see

<blockquote>
<a href="http://www.cs.wisc.edu/~ghost/mac/">http://www.cs.wisc.edu/~ghost/mac/</a>
</blockquote>
</ul>

<p>
It is very likely that Ghostscript will run under other versions of DOS,
and other versions of Unix that support X11, but it has not been tested in
these environments.  (Ghostscript does not run well on PC-compatibles with
Hercules display cards, since text and graphics output interfere with each
other, but you can work around this by redirecting the text output to a file.)

<p>
Ghostscript has also been ported to a number of platforms by users, who are
willing to be contacted about problems on those specific platforms:

<h1><a name="Related_work"></a>Related work</h1>

<h2><a name="PDF_encryption"></a>PDF encryption</h2>

<p>
Geoff Keating has created code to allow processing encrypted PDF files.
Unfortunately, current U.S. export control laws don't allow redistribution
of this code from a site in the U.S., even though it's freely available to
anyone anywhere in the world from Geoff's site in Australia:

<blockquote>
<a href="http://www.ozemail.com.au/~geoffk/pdfencrypt/">http://www.ozemail.com.au/~geoffk/pdfencrypt/</a>
</blockquote>

<p>
The change is a single file of PostScript code, <b><tt>pdf_sec.ps</tt></b>,
which replaces a file in the standard Ghostscript fileset, so it can be
added to a running version of Ghostscript without rebuilding anything.  A
full explanation and instructions are on Geoff's page.

<h2><a name="Previewers"></a>Previewers</h2>

<p>
The Ghostscript user interface is very primitive, so several people have
contributed screen previewers with better user interfaces.

<h3><a name="Previewer_X"></a>Previewers for X Windows</h3>

<p>
We know of three freely available X Windows screen previewers based on
Ghostscript: <b><tt>Ghostview</tt></b>, <b><tt>gv</tt></b>, and
<b><tt>GSPreview</tt></b>.  Most users who have expressed an opinion prefer
<b><tt>gv</tt></b> over <b><tt>Ghostview</tt></b>.

<dl>
<dt><b><tt>gv</tt></b>
<dd>gv, which is derived from Ghostview, is available from CTAN sites and
through the site of its author, Johannes Plass

the generated PostScript output to the specified printer or to a file.
<b><tt>genscript</tt></b> can be easily extended to handle different output
media, and it has many options which can be used to customize printouts,
including 2-up printing, pagination, complex headers, and many more.  You
