This document is a roadmap to the Ghostscript documentation.
After looking through it, if you want to install Ghostscript and not only
use it, we recommend you read <a href="Install.htm">how to install
Ghostscript</a>, and <a href="Make.htm">how to compile Ghostscript</a> from
source code (which is necessary before installing it on Unix and VMS
systems).

<h2><a name="Theme_roadmap"></a>Document roadmap by theme</h2>
<h3><a name="New_users"></a>What should I read if I'm a new user?</h3>
<ul>
<li>how to <a href="Use.htm">use Ghostscript</a>. This includes both
a quickstart introduction to the commandline version and more extensive
reference material.
<li>detailed information about <a href="Devices.htm">specific
devices</a> that Ghostscript can use for output
<li>more detailed information about how to use Ghostscript under
Unix with <tt>lpr</tt> <a href="Unix-lpr.htm">as a filter</a>
for printing
<li>for information about known problems or to report a new one,
please visit <a href="http://bugs.ghostscript.com/">bugs.ghostscript.com</a>
but remember that free versions of Ghostscript come with with
<strong>NO WARRANTY</strong> and <strong>NO SUPPORT</strong>
</ul>
<h3><a name="Two_Ghostscripts"></a>GPL and commercial Ghostscript</h3>
<p>
GPL Ghostscript, Artifex Ghostscript and AFPL Ghostscript are <a href="Commprod.htm">different releases</a>.
<ul>
<li>additional information about <a href="COPYING">GPL Ghostscript
releases</a> that is not relevant to commercial versions.
</ul>
<p>
If you run into any questions, or if you are going to be using Ghostscript
extensively, you should at least skim, and probably eventually read:
<ul>
<li> about the <a href="Fonts.htm">fonts distributed with
Ghostscript</a>, including how to add or replace fonts
<li> a description of <a href="Language.htm">the Ghostscript language</a>,
and its differences from the documented PostScript language
<li> about the <a href="Psfiles.htm">postscript files distributed with
Ghostscript</a> (other than fonts)
</ul>
<h3><a name="Before_building"></a>Before building Ghostscript</h3>
<p>
If you are going to compile Ghostscript from source, rather than just use an executable
you got from somewhere, you may want to read:
<ul>
<li> <a href="Make.htm">how to build Ghostscript</a> and
<a href="Install.htm">install it</a>
</ul>
<hr>
<h2><a name="Not_a_new_user"></a>What should I read if I'm not a new user?</h2>
<p>
If you have already used Ghostscript, when you receive a new release you
should begin by reading this file, then
<ul>
<li> <a href="News.htm">News.htm</a>, for incompatible changes and new
features in the current release;
<li> if you wish, History#.htm (currently <a
href="History9.htm">History9.htm</a>), for changes in the current and earlier releases.
</ul>
<hr>
<h2><a name="Developer"></a>What if I'm a developer?</h2>
<p>
If you are going to do any development on or with Ghostscript at all, you
should at least look at
<ul>
<li>the <a href="Develop.htm">roadmap documentation</a> for Ghostscript's
source files and architecture
</ul>
<p>
If you are going to write a new driver for Ghostscript, you should read
<ul>
<li> the <a href="Source.htm">guide to the Ghostscript source code</a>
<li> the interface between Ghostscript and <a href="Drivers.htm">device
drivers</a>
<li> about the <a href="Xfonts.htm">external font interface</a> between
Ghostscript and platform-supplied fonts
</ul>
<p>
If you are considering distributing GPL Ghostscript in conjunction
with a commercial product, you should read the
<a href="COPYING">license</a> carefully, and you should also read
<ul>
<li> additional clarification of the circumstances under which Ghostscript
can be distributed <a href="Commprod.htm">with a commercial product</a>
</ul>
<p>
If you intend to use Ghostscript in the form of a dynamic link library
(DLL) under OS/2 or Microsoft Windows or in the form of shared object
under Linux, read
<ul>
<li> documentation on <a href="API.htm">Ghostscript Interpreter API</a>
</ul>
<p>
If you want to use Ghostscript as part of another program--as a callable
PostScript language interpreter--and not as a DLL or as a self-contained
executable application, you should begin by reading
<ul>
<li> the source file <code>imain.h</code>, the documented
API for Ghostscript <em>not</em> as a DLL
</ul>
<p>
or if you are going to use only the Ghostscript graphics library,
<ul>
<li> about the structure of the <a href="Lib.htm">Ghostscript library</a>
and its interfaces
</ul>
<hr>
<h2><a name="Writer"></a>What if I'm writing documentation?</h2>
<p>
If you are editing or adding to Ghostscript's existing documentation in
HTML format, or writing a new document, you should read
<hr>
<h2><a name="Web_presence"></a>Presence on the World Wide Web</h2>
<h3><a name="Web_home_page"></a>Ghostscript's home page</h3>
<p>
Ghostscript has a home page on the World Wide Web with helpful information
such as the FAQ (Frequently Asked Questions) and a list of known problems
and workarounds for the current GPL Ghostscript release (in the
"Obtaining" file for that release):
