| placed by the copyright holder saying it may be distributed under the terms |
| of this General Public License. The “<span class="quote">Program</span>”, below, refers to any such |
| program or work, and a |
| “<span class="quote">work based on the Program</span>” means either |
| the Program or any derivative work under copyright law: that is to say, a |
| work containing the Program or a portion of it, either verbatim or with |
| modifications and/or translated into another language. (Hereinafter, translation |
| is included without limitation in the term |
| “<span class="quote">modification</span>”.) Each licensee is addressed as “<span class="quote">you</span>”.</p><p>Activities other than copying, distribution and modification are not covered by |
| this License; they are outside its scope. The act of running the Program is not |
| restricted, and the output from the Program is covered only if its contents |
| constitute a work based on the Program (independent of having been made by running |
| the Program). Whether that is true depends on what the Program does.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-1"></a>Section 1</h3></div></div></div><p>You may copy and distribute verbatim copies of the Program's source code as you |
| receive it, in any medium, provided that you conspicuously and appropriately |
| publish on each copy an appropriate copyright notice and disclaimer of warranty; |
| keep intact all the notices that refer to this License and to the absence of any |
| warranty; and give any other recipients of the Program a copy of this License |
| along with the Program.</p><p>You may charge a fee for the physical act of transferring a copy, and you may at |
| your option offer warranty protection in exchange for a fee.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-2"></a>Section 2</h3></div></div></div><p>You may modify your copy or copies of the Program or any portion of it, thus |
| forming a work based on the Program, and copy and distribute such modifications |
| or work under the terms of |
| <a class="link" href="bk01apds02.html#gpl-2-1" title="Section 1">Section 1</a> above, provided |
| that you also meet all of these conditions: |
| </p><div class="orderedlist"><ol type="a"><li><p>You must cause the modified files to carry prominent notices stating that |
| you changed the files and the date of any change.</p></li><li><p>You must cause any work that you distribute or publish, that in whole or |
| in part contains or is derived from the Program or any part thereof, to be |
| licensed as a whole at no charge to all third parties under the terms of |
| this License.</p></li><li><p>If the modified program normally reads commands interactively when run, you |
| must cause it, when started running for such interactive use in the most |
| ordinary way, 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) and that users may redistribute the program |
| under these conditions, and telling the user how to view a copy of this |
| License. (Exception: If the Program itself is interactive but does not |
| normally print such an announcement, your work based on the Program is not |
| required to print an announcement.)</p></li></ol></div><p> |
| </p><p>These requirements apply to the modified work as a whole. If identifiable sections |
| of that work are not derived from the Program, and can be reasonably considered |
| independent and separate works in themselves, then this License, and its terms, |
| do not apply to those sections when you distribute them as separate works. But when |
| you distribute the same sections as part of a whole which is a work based on the |
| Program, the distribution of the whole must be on the terms of this License, whose |
| permissions for other licensees extend to the entire whole, and thus to each and |
| every part regardless of who wrote it.</p><p>Thus, it is not the intent of this section to claim rights or contest your rights |
| to work written entirely by you; rather, the intent is to exercise the right to control |
| the distribution of derivative or collective works based on the Program.</p><p>In addition, mere aggregation of another work not based on the Program with the Program |
| (or with a work based on the Program) on a volume of a storage or distribution medium |
| does not bring the other work under the scope of this License.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-3"></a>Section 3</h3></div></div></div><p>You may copy and distribute the Program (or a work based on it, under |
| <a class="link" href="bk01apds02.html#gpl-2-2" title="Section 2">Section 2</a> in object code or executable form under the terms of |
| <a class="link" href="bk01apds02.html#gpl-2-1" title="Section 1">Sections 1</a> and |
| <a class="link" href="bk01apds02.html#gpl-2-2" title="Section 2">2</a> above provided that you also do one of the following: |
| </p><div class="orderedlist"><ol type="a"><li><p>Accompany it with the complete corresponding machine-readable source code, which |
| must be distributed under the terms of Sections 1 and 2 above on a medium |
| customarily used for software interchange; or,</p></li><li><p>Accompany it with a written offer, valid for at least three years, to give any |
| third party, for a charge no more than your cost of physically performing source |
| distribution, a complete machine-readable copy of the corresponding source code, |
| to be distributed under the terms of Sections 1 and 2 above on a medium customarily |
| used for software interchange; or,</p></li><li><p>Accompany it with the information you received as to the offer to distribute |
| corresponding source code. (This alternative is allowed only for noncommercial |
| distribution and only if you received the program in object code or executable form |
| with such an offer, in accord with Subsection b above.)</p></li></ol></div><p> |
| </p><p>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. However, as a special exception, the source |
| code distributed need not include anything 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, unless that component itself accompanies the executable.</p><p>If distribution of executable or object code is made by offering access to copy from a |
| designated place, then offering equivalent access 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 along with the object code.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-4"></a>Section 4</h3></div></div></div><p>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.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-5"></a>Section 5</h3></div></div></div><p>You are not required to accept this License, since you have not signed it. However, nothing |
| else grants you permission to modify or distribute the Program or its derivative works. |
| These actions are prohibited by law if you do not accept this License. Therefore, 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.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-6"></a>Section 6</h3></div></div></div><p>Each time you redistribute the Program (or any work based on the Program), the recipient |
| automatically receives a license from the original licensor to copy, distribute or modify |
| the Program subject to these terms and conditions. You may not impose any further restrictions |
| on the recipients' exercise of the rights granted herein. You are not responsible for enforcing |
| compliance by third parties to this License.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-7"></a>Section 7</h3></div></div></div><p>If, as a consequence of a court judgment or allegation of patent infringement or for any other |
| reason (not limited to patent issues), conditions are imposed on you (whether by court order, |
| agreement or otherwise) that contradict the conditions of this License, they do not excuse you |
| from the conditions of this License. If you cannot distribute so as to satisfy simultaneously |
| your obligations under this License and any other pertinent obligations, then as a consequence |
| you may not distribute the Program at all. For example, if a patent license would not permit |
| royalty-free redistribution of the Program by all those who receive copies directly or |
| indirectly through you, then the only way you could satisfy both it and this License would be |
| to refrain entirely from distribution of the Program.</p><p>If any portion of this section is held invalid or unenforceable under any particular circumstance, |
| the balance of the section is intended to apply and the section as a whole is intended to apply |
| in other circumstances.</p><p>It is not the purpose of this section to induce you to infringe any patents or other property |
| right claims or to contest validity of any such claims; this section has the sole purpose of |
| protecting the integrity of the free software distribution system, which is implemented by public |
| license practices. Many people have made generous contributions to the wide range of software |
| distributed through that system in reliance on consistent application of that system; it is up |
| to the author/donor to decide if he or she is willing to distribute software through any other |
| system and a licensee cannot impose that choice.</p><p>This section is intended to make thoroughly clear what is believed to be a consequence of the |
| rest of this License.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-8"></a>Section 8</h3></div></div></div><p>If the distribution and/or use of the Program is restricted in certain countries either by patents |
| or by copyrighted interfaces, the original copyright holder who places the Program under this License |
| 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.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-9"></a>Section 9</h3></div></div></div><p>The Free Software Foundation may publish revised and/or new versions of the General Public License |
| from time to time. Such new versions will be similar in spirit to the present version, but may differ |
| in detail to address new problems or concerns.</p><p>Each version is given a distinguishing version number. If the Program specifies a version number of |
| this License which applies to it and “<span class="quote">any later version</span>”, you have the option of following the terms |
| and conditions either of that version or of any later version published by the Free Software |
| Foundation. If the Program does not specify a version number of this License, you may choose any |
| version ever published by the Free Software Foundation.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-10"></a>Section 10</h3></div></div></div><p>If you wish to incorporate parts of the Program into other free programs whose distribution |
| conditions are different, write to the author to ask for permission. For software which is copyrighted |
| by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions |
| for this. Our decision will be guided by the two goals of preserving the free status of all |
| derivatives of our free software and of promoting the sharing and reuse of software generally.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-11"></a>NO WARRANTY Section 11</h3></div></div></div><p>BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT |
| PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR |
| OTHER PARTIES PROVIDE THE PROGRAM “<span class="quote">AS IS</span>” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, |
| INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
| PURPOSE. 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.</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="gpl-2-12"></a>Section 12</h3></div></div></div><p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, 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.</p><p>END OF TERMS AND CONDITIONS</p></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="bk01apd.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="bk01apd.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="bk01apds03.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Appendix D.
