4 placed by the copyright holder saying it may be distributed under the terms
5 of this General Public License. The “<span class="quote">Program</span>”, below, refers to any such
7 “<span class="quote">work based on the Program</span>” means either
8 the Program or any derivative work under copyright law: that is to say, a
9 work containing the Program or a portion of it, either verbatim or with
10 modifications and/or translated into another language. (Hereinafter, translation
11 is included without limitation in the term
12 “<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
13 this License; they are outside its scope. The act of running the Program is not
14 restricted, and the output from the Program is covered only if its contents
15 constitute a work based on the Program (independent of having been made by running
16 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
17 receive it, in any medium, provided that you conspicuously and appropriately
18 publish on each copy an appropriate copyright notice and disclaimer of warranty;
19 keep intact all the notices that refer to this License and to the absence of any
20 warranty; and give any other recipients of the Program a copy of this License
21 along with the Program.</p><p>You may charge a fee for the physical act of transferring a copy, and you may at
22 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
23 forming a work based on the Program, and copy and distribute such modifications
24 or work under the terms of
25 <a class="link" href="bk01apds02.html#gpl-2-1" title="Section 1">Section 1</a> above, provided
26 that you also meet all of these conditions:
27 </p><div class="orderedlist"><ol type="a"><li><p>You must cause the modified files to carry prominent notices stating that
28 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
29 in part contains or is derived from the Program or any part thereof, to be
30 licensed as a whole at no charge to all third parties under the terms of
31 this License.</p></li><li><p>If the modified program normally reads commands interactively when run, you
32 must cause it, when started running for such interactive use in the most
33 ordinary way, to print or display an announcement including an appropriate
34 copyright notice and a notice that there is no warranty (or else, saying
35 that you provide a warranty) and that users may redistribute the program
36 under these conditions, and telling the user how to view a copy of this
37 License. (Exception: If the Program itself is interactive but does not
38 normally print such an announcement, your work based on the Program is not
39 required to print an announcement.)</p></li></ol></div><p>
40 </p><p>These requirements apply to the modified work as a whole. If identifiable sections
41 of that work are not derived from the Program, and can be reasonably considered
42 independent and separate works in themselves, then this License, and its terms,
43 do not apply to those sections when you distribute them as separate works. But when
44 you distribute the same sections as part of a whole which is a work based on the
45 Program, the distribution of the whole must be on the terms of this License, whose
46 permissions for other licensees extend to the entire whole, and thus to each and
47 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
48 to work written entirely by you; rather, the intent is to exercise the right to control
49 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
50 (or with a work based on the Program) on a volume of a storage or distribution medium
51 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
52 <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
53 <a class="link" href="bk01apds02.html#gpl-2-1" title="Section 1">Sections 1</a> and
54 <a class="link" href="bk01apds02.html#gpl-2-2" title="Section 2">2</a> above provided that you also do one of the following:
55 </p><div class="orderedlist"><ol type="a"><li><p>Accompany it with the complete corresponding machine-readable source code, which
56 must be distributed under the terms of Sections 1 and 2 above on a medium
57 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
58 third party, for a charge no more than your cost of physically performing source
59 distribution, a complete machine-readable copy of the corresponding source code,
60 to be distributed under the terms of Sections 1 and 2 above on a medium customarily
61 used for software interchange; or,</p></li><li><p>Accompany it with the information you received as to the offer to distribute
62 corresponding source code. (This alternative is allowed only for noncommercial
63 distribution and only if you received the program in object code or executable form
64 with such an offer, in accord with Subsection b above.)</p></li></ol></div><p>
65 </p><p>The source code for a work means the preferred form of the work for making modifications
66 to it. For an executable work, complete source code means all the source code for all modules
67 it contains, plus any associated interface definition files, plus the scripts used to control
68 compilation and installation of the executable. However, as a special exception, the source
69 code distributed need not include anything that is normally distributed (in either source or
70 binary form) with the major components (compiler, kernel, and so on) of the operating system
71 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
72 designated place, then offering equivalent access to copy the source code from the same place
73 counts as distribution of the source code, even though third parties are not compelled to
74 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
75 under this License. Any attempt otherwise to copy, modify, sublicense or distribute the
76 Program is void, and will automatically terminate your rights under this License. However,
77 parties who have received copies, or rights, from you under this License will not have their
78 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
79 else grants you permission to modify or distribute the Program or its derivative works.
80 These actions are prohibited by law if you do not accept this License. Therefore, by modifying
81 or distributing the Program (or any work based on the Program), you indicate your acceptance
82 of this License to do so, and all its terms and conditions for copying, distributing or
83 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
84 automatically receives a license from the original licensor to copy, distribute or modify
85 the Program subject to these terms and conditions. You may not impose any further restrictions
86 on the recipients' exercise of the rights granted herein. You are not responsible for enforcing
87 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
88 reason (not limited to patent issues), conditions are imposed on you (whether by court order,
89 agreement or otherwise) that contradict the conditions of this License, they do not excuse you
90 from the conditions of this License. If you cannot distribute so as to satisfy simultaneously
91 your obligations under this License and any other pertinent obligations, then as a consequence
92 you may not distribute the Program at all. For example, if a patent license would not permit
93 royalty-free redistribution of the Program by all those who receive copies directly or
94 indirectly through you, then the only way you could satisfy both it and this License would be
95 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,
96 the balance of the section is intended to apply and the section as a whole is intended to apply
97 in other circumstances.</p><p>It is not the purpose of this section to induce you to infringe any patents or other property
98 right claims or to contest validity of any such claims; this section has the sole purpose of
99 protecting the integrity of the free software distribution system, which is implemented by public
100 license practices. Many people have made generous contributions to the wide range of software
101 distributed through that system in reliance on consistent application of that system; it is up
102 to the author/donor to decide if he or she is willing to distribute software through any other
103 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
104 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
105 or by copyrighted interfaces, the original copyright holder who places the Program under this License
106 may add an explicit geographical distribution limitation excluding those countries, so that
107 distribution is permitted only in or among countries not thus excluded. In such case, this License
108 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
109 from time to time. Such new versions will be similar in spirit to the present version, but may differ
110 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
111 this License which applies to it and “<span class="quote">any later version</span>”, you have the option of following the terms
112 and conditions either of that version or of any later version published by the Free Software
113 Foundation. If the Program does not specify a version number of this License, you may choose any
114 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
115 conditions are different, write to the author to ask for permission. For software which is copyrighted
116 by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions
117 for this. Our decision will be guided by the two goals of preserving the free status of all
118 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
119 PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
120 OTHER PARTIES PROVIDE THE PROGRAM “<span class="quote">AS IS</span>” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
121 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
122 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
123 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
124 ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
125 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
126 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
127 INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH
128 ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
129 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.
