                          Aladdin Free Public License
                        (Version 9, September 18, 2000)

   Copyright (C) 1994, 1995, 1997, 1998, 1999, 2000 Aladdin Enterprises,
            Menlo Park, California, U.S.A. All rights reserved.

     NOTE: This License is not the same as any of the GNU Licenses
     published by the Free Software Foundation. Its terms are
     substantially different from those of the GNU Licenses. If you are
     familiar with the GNU Licenses, please read this license with extra
     care.

   Aladdin Enterprises hereby grants to anyone the permission to apply
   this License to their own work, as long as the entire License
   (including the above notices and this paragraph) is copied with no
   changes, additions, or deletions except for changing the first
   paragraph of Section 0 to include a suitable description of the work
   to which the license is being applied and of the person or entity that
   holds the copyright in the work, and, if the License is being applied
   to a work created in a country other than the United States, replacing
   the first paragraph of Section 6 with an appropriate reference to the
   laws of the appropriate country.

   This License is not an Open Source license: among other things, it
   places restrictions on distribution of the Program, specifically
   including sale of the Program. While Aladdin Enterprises respects and
   supports the philosophy of the Open Source Definition, and shares the
   desire of the GNU project to keep licensed software freely
   redistributable in both source and object form, we feel that Open
   Source licenses unfairly prevent developers of useful software from
   being compensated proportionately when others profit financially from
   their work. This License attempts to ensure that those who receive,
   redistribute, and contribute to the licensed Program according to the
   Open Source and Free Software philosophies have the right to do so,
   while retaining for the developer(s) of the Program the power to make
   those who use the Program to enhance the value of commercial products
   pay for the privilege of doing so.

0. Subject Matter

   This License applies to the computer program known as "AFPL
   Ghostscript." The "Program", below, refers to such program. The
   Program is a copyrighted work whose copyright is held by artofcode
   LLC, located in Benicia, California (the "Licensor"). Please note that
   AFPL Ghostscript is neither the program known as "GNU Ghostscript" nor
   the version of Ghostscript available for commercial licensing from
   Artifex Software Inc.

   A "work based on the Program" means either the Program or any
   derivative work of the Program, as defined in the United States
   Copyright Act of 1976, such as a translation or a modification.

   BY MODIFYING OR DISTRIBUTING THE PROGRAM (OR ANY WORK BASED ON THE
   PROGRAM), YOU INDICATE YOUR ACCEPTANCE OF THIS LICENSE TO DO SO, AND
   ALL ITS TERMS AND CONDITIONS FOR COPYING, DISTRIBUTING OR MODIFYING
   THE PROGRAM OR WORKS BASED ON IT. NOTHING OTHER THAN THIS LICENSE
   GRANTS YOU PERMISSION TO MODIFY OR DISTRIBUTE THE PROGRAM OR ITS
   DERIVATIVE WORKS. THESE ACTIONS ARE PROHIBITED BY LAW. IF YOU DO NOT
   ACCEPT THESE TERMS AND CONDITIONS, DO NOT MODIFY OR DISTRIBUTE THE
   PROGRAM. 

1. Licenses.

   Licensor hereby grants you the following rights, provided that you
   comply with all of the restrictions set forth in this License and
   provided, further, that you distribute an unmodified copy of this
   License with the Program:
   (a)
          You may copy and distribute literal (i.e., verbatim) copies of
          the Program's source code as you receive it throughout the
          world, in any medium.
   (b)
          You may modify the Program, create works based on the Program
          and distribute copies of such throughout the world, in any
          medium.

2. Restrictions.

   This license is subject to the following restrictions:
   (a)
          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).
          The following methods of distribution involving payment shall
          not in and of themselves be a violation of this restriction:
        (i)
               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) and that access to
               the service and to the Program is available independent of
               any other product or service. An example of a service that
               does not fall under this section is an on-line service
               that is operated by a company and that is only available
               to customers of that company. (This is not an exhaustive
               enumeration.)
        (ii)
               Distributing the Program on removable computer-readable
               media, provided that the files containing the Program are
               reproduced entirely and verbatim on such media, that all
               information on such media be redistributable for
               non-commercial purposes without charge, and that such
               media are distributed by themselves (except for
               accompanying documentation) independent of any other
               product or service. Examples of such media include CD-ROM,
               magnetic tape, and optical storage media. (This is not
               intended to be an exhaustive list.) An example of a
               distribution that does not fall under this section is a
               CD-ROM included in a book or magazine. (This is not an
               exhaustive enumeration.)
   (b)
          Activities other than copying, distribution and modification of
          the Program are not subject to this License and they are
          outside its scope. Functional use (running) of the Program is
          not restricted, and any output produced through the use of the
          Program is subject to this license only if its contents
          constitute a work based on the Program (independent of having
          been made by running the Program).
   (c)
          You must meet all of the following conditions with respect to
          any work that you distribute or publish that in whole or in
          part contains or is derived from the Program or any part
          thereof ("the Work"):
        (i)
               If you have modified the Program, you must cause the Work
               to carry prominent notices stating that you have modified
               the Program's files and the date of any change. In each
               source file that you have modified, you must include a
               prominent notice that you have modified the file,
               including your name, your e-mail address (if any), and the
               date and purpose of the change;
        (ii)
               You must cause the Work to be licensed as a whole and at
               no charge to all third parties under the terms of this
               License;
        (iii)
               If the Work normally reads commands interactively when
               run, you must cause it, at each time the Work commences
               operation, to print or display an announcement including
               an appropriate copyright notice and a notice that there is
               no warranty (or else, saying that you provide a warranty).
               Such notice must also state that users may redistribute
               the Work only under the conditions of this License and
               tell the user how to view the copy of this License
               included with the Work. (Exceptions: if the Program is
               interactive but normally prints or displays such an
               announcement only at the request of a user, such as in an
               "About box", the Work is required to print or display the
               notice only under the same circumstances; if the Program
               itself is interactive but does not normally print such an
               announcement, the Work is not required to print an
               announcement.);
        (iv)
               You must accompany the Work with the complete
               corresponding machine-readable source code, delivered on a
               medium customarily used for software interchange. The
               source code for a work means the preferred form of the
               work for making modifications to it. For an executable
               work, complete source code means all the source code for
               all modules it contains, plus any associated interface
               definition files, plus the scripts used to control
               compilation and installation of the executable code. If
               you distribute with the Work any component that is
               normally distributed (in either source or binary form)
               with the major components (compiler, kernel, and so on) of
               the operating system on which the executable runs, you
               must also distribute the source code of that component if
               you have it and are allowed to do so;
        (v)
               If you distribute any written or printed material at all
               with the Work, such material must include either a written
               copy of this License, or a prominent written indication
               that the Work is covered by this License and written
               instructions for printing and/or displaying the copy of
               the License on the distribution medium;
        (vi)
               You may not impose any further restrictions on the
               recipient's exercise of the rights granted herein.

   If distribution of executable or object code is made by offering the
   equivalent ability to copy from a designated place, then offering
   equivalent ability to copy the source code from the same place counts
   as distribution of the source code, even though third parties are not
   compelled to copy the source code along with the object code.

  3. Reservation of Rights.

   No rights are granted to the Program except as expressly set forth
   herein. You may not copy, modify, sublicense, or distribute the
   Program except as expressly provided under this License. Any attempt
   otherwise to copy, modify, sublicense or distribute the Program is
   void, and will automatically terminate your rights under this License.
   However, parties who have received copies, or rights, from you under
   this License will not have their licenses terminated so long as such
   parties remain in full compliance.

  4. Other Restrictions.

   If the distribution and/or use of the Program is restricted in certain
   countries for any reason, Licensor may add an explicit geographical
   distribution limitation excluding those countries, so that
   distribution is permitted only in or among countries not thus
   excluded. In such case, this License incorporates the limitation as if
   written in the body of this License.

  5. Limitations.

   THE PROGRAM IS PROVIDED TO YOU "AS IS," WITHOUT WARRANTY. THERE IS NO
   WARRANTY FOR THE PROGRAM, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
   NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
   FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF THIRD PARTY RIGHTS.
   THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS
   WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
   ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 

   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   WILL LICENSOR, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
   THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
   INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
   ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
   NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
   LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
   TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
   PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 

  6. General.

   This License is governed by the laws of the State of California,
   U.S.A., excluding choice of law rules.

   If any part of this License is found to be in conflict with the law,
   that part shall be interpreted in its broadest meaning consistent with
   the law, and no other parts of the License shall be affected.

   For United States Government users, the Program is provided with
   RESTRICTED RIGHTS. If you are a unit or agency of the United States
   Government or are acquiring the Program for any such unit or agency,
   the following apply:

     If the unit or agency is the Department of Defense ("DOD"), the
     Program and its documentation are classified as "commercial
     computer software" and "commercial computer software documentation"
     respectively and, pursuant to DFAR Section 227.7202, the Government
     is acquiring the Program and its documentation in accordance with
     the terms of this License. If the unit or agency is other than DOD,
     the Program and its documentation are classified as "commercial
     computer software" and "commercial computer software documentation"
     respectively and, pursuant to FAR Section 12.212, the Government is
     acquiring the Program and its documentation in accordance with the
     terms of this License.
