+<h2><a name="Free_version"></a>Use of the public-access "free"
+version of Ghostscript</h2>
+
+<p>
+Ghostscript is a copyrighted work whose copyright is owned by Aladdin
+Enterprises. Some versions of Ghostscript are distributed freely under the
+name AFPL Ghostscript; these versions are always distributed with a
+license, called the <a href="Public.htm">Aladdin Free Public
+License</a>
+(also known as the AFPL), which permits AFPL Ghostscript to be
+redistributed freely under certain conditions. These conditions will
+almost always be met easily by individuals in their personal use of AFPL
+Ghostscript. AFPL Ghostscript may be <em>used</em> freely, including by
+commercial entities for evaluation or unsupported internal use. However,
+<em>distribution</em> for commercial purposes of Ghostscript, or anything
+containing or derived from Ghostscript in whole or in part, generally
+requires a written commercial license from <a href="#Artifex">Artifex
+Software Inc.</a>, the sole entity authorized by Aladdin Enterprises to
+grant such licenses. More specifically, the AFPL states:
+
+<blockquote>
+Distribution of the Program or any work based on the Program by a
+commercial organization to any third party is prohibited if any payment is
+made in connection with such distribution, whether directly (as in payment
+for a copy of the Program) or indirectly (as in payment for some service
+related to the Program, or payment for some product or service that
+includes a copy of the Program "without charge"; these are only examples,
+and not an exhaustive enumeration of prohibited activities). However, the
+following methods of distribution involving payment shall not in and of
+themselves be a violation of this restriction:
+
+<dl compact>
+<dt>(i)<dd>Posting the Program on a public access information storage and
+retrieval service for which a fee is received for retrieving information
+(such as an on-line service), provided that the fee is not
+content-dependent (i.e., the fee would be the same for retrieving the same
+volume of information consisting of random data).
+
+<dt>(ii)<dd>Distributing the Program on a CD-ROM, provided that the files
+containing the Program are reproduced entirely and verbatim on such CD-ROM,
+and provided further that all information on such CD-ROM be redistributable
+for non-commercial purposes without charge.
+</dl>
+</blockquote>
+
+<p>
+The intent of the exception provided in clause (i) is to allow commercial
+organizations operating an FTP server or a bulletin board to distribute
+AFPL Ghostscript freely from it, provided that:
+
+<dl compact>
+<dt>(1)<dd>the organization complies with the other provisions of the
+AFPL, which include among other things a requirement to distribute the
+full source code of AFPL Ghostscript and of any derived work, and to
+distribute the AFPL itself along with AFPL Ghostscript;
+
+<dt>(2)<dd>the only charge for downloading AFPL Ghostscript is a charge
+based on the distribution service and not one based on the content of the
+information being retrieved (i.e., the charge would be the same for
+retrieving a random collection of bits of the same size);
+
+<dt>(3)<dd>the server or BBS is accessible to the general public, i.e.,
+the phone number or IP address is not kept secret, and anyone may obtain
+access to the information (possibly by paying a subscription or access fee
+that is not dependent on or related to purchasing anything else).
+</dl>
+
+<p>
+Similarly, the exception in clause (ii) is intended to allow inclusion of
+AFPL Ghostscript on "freeware" CD-ROMs that contain only material that
+is in the public domain, or is freely redistributable provided only that a
+copyright notice is retained (such as the Independent JPEG Group
+libraries), or is distributed under some other kind of license allowing
+free redistribution such as the GNU
+<a href="http://www.gnu.org/copyleft/gpl.html">General Public License</a>.
+
+<p>
+If you want to distribute software in a commercial context that
+incorporates Ghostscript and you do <em>not</em> want to meet these
+conditions, you should contact <a href="#Artifex">Artifex Software</a> to
+find out about commercial licensing. Commercial licenses involve a
+(negotiated) payment, and include support and other benefits. These are
+the only ways you legally can distribute Ghostscript or anything containing
+Ghostscript: either by distributing AFPL Ghostscript under the
+requirements of the AFPL, or by getting a commercial license from Artifex
+Software.

+
+<h2><a name="GPL"></a>The GNU General Public License (GPL)</h2>
+
+<p>
+Older versions of Ghostscript (versions of 5.50 and previous) were
+distributed with a license called the GNU
+<a href="http://www.gnu.org/copyleft/gpl.html">General Public License</a>
+(also known as the "GNU License", the "GPL", or "copyleft"), which
+allowed distribution with commercial products under certain conditions.
+Aladdin Enterprises may choose to distribute other versions of Ghostscript
+with the GPL in the future; however, these versions will be identified as
+"GNU Ghostscript." The remainder of this section applies only to versions
+identified explicitly as GNU Ghostscript versions; the generic name
+Ghostscript, when applied to versions above 4.03, refers to AFPL
+Ghostscript, which is governed by the Aladdin Free Public License, not the
+GPL.
+
+<p>
+The full GPL is included under the name
+<b><tt>COPYING</tt></b> in the GNU Ghostscript fileset, and
+can also be obtained directly from the Free Software Foundation:
+
+<blockquote><address><a name="FSF_address"></a>

+or in Japan by free dial fax:
+
+<blockquote><address>

+</address></blockquote>
+
+<p>
+The GPL gotten directly from the FSF or the contents of the
+<b><tt>COPYING</tt></b> file are authoritative, but for those
+unfamiliar with the GPL, we now summarize its provisions.
+
+<dl compact>
+<dt>1.<dd>Anyone may copy and distribute GNU Ghostscript (both source and
+object code), but they must distribute the source code as well as the
+object code (or, if they distribute only the object code, they must
+include an offer in writing to provide the source code at no more than
+reproduction cost), keep all copyright and other notices, and include the
+GPL with the copies. (Note that this allows anyone receiving such a copy
+to distribute it freely as well.)
+
+<dt>2.<dd>Anyone may modify GNU Ghostscript, but the provisions of (1)
+apply to modified or derived works as well.
+
+<dt>3.<dd>GNU Ghostscript may be "aggregated" with another program; in
+this case, (1) and (2) do not apply to the other program, but only to GNU
+Ghostscript.
+</dl>
+
+<p>
+Provision (1) makes it much harder to have a commercial business based only
+on selling copies of GNU Ghostscript (as distributed with the GPL) or
+products that contain GNU Ghostscript, since any customer is free to make
+as many copies as they want for any purpose. Provision (2) effectively
+prevents the development of proprietary commercial products that
+incorporate GNU Ghostscript without a commercial license as a part, since
+these are "derived works" in the legal sense.
+
+<p>
+Questions have arisen at times in particular cases regarding provision (3)
+as to whether GNU Ghostscript is "aggregated" with other parts of a
+commercial product, or whether the product has become a "derived work."
+Normally, combining GNU Ghostscript with another piece of software creates
+a "derived work"; we consider GNU Ghostscript to be "aggregated" with
+another piece of software, which we will refer to as "the application",
+only if all of the following conditions are met:
+
+<ul>
+<li> The code and documentation for GNU Ghostscript are physically
+separated from the code and documentation for the application. For
+electronic form, it is both necessary and sufficient to put the GNU
+Ghostscript code and documentation in their own directory tree(s).
+
+<li> GNU Ghostscript, as delivered with the application, is usable
+independently of the application. More precisely, if a user deletes from
+the computer system all files delivered with the application except those
+in the GNU Ghostscript directories, the user will still be able to use GNU
+Ghostscript as described in GNU Ghostscript's documentation. Among other
+things, this requires that GNU Ghostscript not call any routines in the
+application, and not require any data or other files supplied as part of
+the application.
+
+<li> The application calls GNU Ghostscript in a way that allows an ordinary
+user to substitute another program for GNU Ghostscript. (Typically this
+requires use of a shell script or batch file, or a system call like
+"<b><tt>exec</tt></b>".) More precisely, if the user deletes from the
+computer system all the files in the GNU Ghostscript directories, and
+replaces the GNU Ghostscript executable with another program with the same
+name and conforming to the same documentation, the application will
+continue to work with it. One implication of this is that the GNU
+Ghostscript documentation must specify all properties of GNU Ghostscript on
+which the application relies; for example, if GNU Ghostscript has been
+modified by the addition of command line switches or language elements such
+as new operators, the documentation must describe any such additions that
+the application uses.
+
+<li> The conditions of the GPL are met with respect to GNU Ghostscript,
+including the requirement for propagation of the GPL and the requirement
+for delivering (or an offer to deliver) source code.
+</ul>
+
+<p>
+Regarding this last point, the GPL clearly intends that if the distributor
+only offers to provide the GNU Ghostscript source code (as opposed to
+actually distributing the source code with every copy of the application),
+then they must deliver the source code in a timely way to anyone
+requesting it.
+
+<p>
+The GPL makes it clear that if someone receives GNU Ghostscript only in
+its GPL-licensed form, they only have a right to distribute it if they
+comply with the GPL. Aladdin Enterprises, as the copyright holder, takes
+this requirement very seriously, and will, if necessary, take legal action
+to ensure that anyone distributing GNU Ghostscript with the GPL complies
+with the conditions set forth above.
