8 pcg 1.1 GNU GENERAL PUBLIC LICENSE
9     Version 2, June 1991
10    
11     Copyright (C) 1989, 1991 Free Software Foundation, Inc.
12 pcg 1.2 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
13 pcg 1.1 Everyone is permitted to copy and distribute verbatim copies
14     of this license document, but changing it is not allowed.
15    
16     Preamble
17    
18     The licenses for most software are designed to take away your
19     freedom to share and change it. By contrast, the GNU General Public
20     License is intended to guarantee your freedom to share and change free
21     software--to make sure the software is free for all its users. This
22     General Public License applies to most of the Free Software
23     Foundation's software and to any other program whose authors commit to
24     using it. (Some other Free Software Foundation software is covered by
25     the GNU Library General Public License instead.) You can apply it to
26     your programs, too.
27    
28     When we speak of free software, we are referring to freedom, not
29     price. Our General Public Licenses are designed to make sure that you
30     have the freedom to distribute copies of free software (and charge for
31     this service if you wish), that you receive source code or can get it
32     if you want it, that you can change the software or use pieces of it
33     in new free programs; and that you know you can do these things.
34    
35     To protect your rights, we need to make restrictions that forbid
36     anyone to deny you these rights or to ask you to surrender the rights.
37     These restrictions translate to certain responsibilities for you if you
38     distribute copies of the software, or if you modify it.
39    
40     For example, if you distribute copies of such a program, whether
41     gratis or for a fee, you must give the recipients all the rights that
42     you have. You must make sure that they, too, receive or can get the
43     source code. And you must show them these terms so they know their
44     rights.
45    
46     We protect your rights with two steps: (1) copyright the software, and
47     (2) offer you this license which gives you legal permission to copy,
48     distribute and/or modify the software.
49    
50     Also, for each author's protection and ours, we want to make certain
51     that everyone understands that there is no warranty for this free
52     software. If the software is modified by someone else and passed on, we
53     want its recipients to know that what they have is not the original, so
54     that any problems introduced by others will not reflect on the original
55     authors' reputations.
56    
57     Finally, any free program is threatened constantly by software
58     patents. We wish to avoid the danger that redistributors of a free
59     program will individually obtain patent licenses, in effect making the
60     program proprietary. To prevent this, we have made it clear that any
61     patent must be licensed for everyone's free use or not licensed at all.
62    
63     The precise terms and conditions for copying, distribution and
64     modification follow.
65    
66     GNU GENERAL PUBLIC LICENSE
67     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
68    
69     0. This License applies to any program or other work which contains
70     a notice placed by the copyright holder saying it may be distributed
71     under the terms of this General Public License. The "Program", below,
72     refers to any such program or work, and a "work based on the Program"
73     means either the Program or any derivative work under copyright law:
74     that is to say, a work containing the Program or a portion of it,
75     either verbatim or with modifications and/or translated into another
76     language. (Hereinafter, translation is included without limitation in
77     the term "modification".) Each licensee is addressed as "you".
78    
79     Activities other than copying, distribution and modification are not
80     covered by this License; they are outside its scope. The act of
81     running the Program is not restricted, and the output from the Program
82     is covered only if its contents constitute a work based on the
83     Program (independent of having been made by running the Program).
84     Whether that is true depends on what the Program does.
85    
86     1. You may copy and distribute verbatim copies of the Program's
87     source code as you receive it, in any medium, provided that you
88     conspicuously and appropriately publish on each copy an appropriate
89     copyright notice and disclaimer of warranty; keep intact all the
90     notices that refer to this License and to the absence of any warranty;
91     and give any other recipients of the Program a copy of this License
92     along with the Program.
93    
94     You may charge a fee for the physical act of transferring a copy, and
95     you may at your option offer warranty protection in exchange for a fee.
96    
97     2. You may modify your copy or copies of the Program or any portion
98     of it, thus forming a work based on the Program, and copy and
99     distribute such modifications or work under the terms of Section 1
100     above, provided that you also meet all of these conditions:
101    
102     a) You must cause the modified files to carry prominent notices
103     stating that you changed the files and the date of any change.
104    
105     b) You must cause any work that you distribute or publish, that in
106     whole or in part contains or is derived from the Program or any
107     part thereof, to be licensed as a whole at no charge to all third
108     parties under the terms of this License.
109    
110     c) If the modified program normally reads commands interactively
111     when run, you must cause it, when started running for such
112     interactive use in the most ordinary way, to print or display an
113     announcement including an appropriate copyright notice and a
114     notice that there is no warranty (or else, saying that you provide
115     a warranty) and that users may redistribute the program under
116     these conditions, and telling the user how to view a copy of this
117     License. (Exception: if the Program itself is interactive but
118     does not normally print such an announcement, your work based on
119     the Program is not required to print an announcement.)
120    
121     These requirements apply to the modified work as a whole. If
122     identifiable sections of that work are not derived from the Program,
123     and can be reasonably considered independent and separate works in
124     themselves, then this License, and its terms, do not apply to those
125     sections when you distribute them as separate works. But when you
126     distribute the same sections as part of a whole which is a work based
127     on the Program, the distribution of the whole must be on the terms of
128     this License, whose permissions for other licensees extend to the
129     entire whole, and thus to each and every part regardless of who wrote it.
130    
131     Thus, it is not the intent of this section to claim rights or contest
132     your rights to work written entirely by you; rather, the intent is to
133     exercise the right to control the distribution of derivative or
134     collective works based on the Program.
135    
136     In addition, mere aggregation of another work not based on the Program
137     with the Program (or with a work based on the Program) on a volume of
138     a storage or distribution medium does not bring the other work under
139     the scope of this License.
140    
141     3. You may copy and distribute the Program (or a work based on it,
142     under Section 2) in object code or executable form under the terms of
143     Sections 1 and 2 above provided that you also do one of the following:
144    
145     a) Accompany it with the complete corresponding machine-readable
146     source code, which must be distributed under the terms of Sections
147     1 and 2 above on a medium customarily used for software interchange; or,
148    
149     b) Accompany it with a written offer, valid for at least three
150     years, to give any third party, for a charge no more than your
151     cost of physically performing source distribution, a complete
152     machine-readable copy of the corresponding source code, to be
153     distributed under the terms of Sections 1 and 2 above on a medium
154     customarily used for software interchange; or,
155    
156     c) Accompany it with the information you received as to the offer
157     to distribute corresponding source code. (This alternative is
158     allowed only for noncommercial distribution and only if you
159     received the program in object code or executable form with such
160     an offer, in accord with Subsection b above.)
161    
162     The source code for a work means the preferred form of the work for
163     making modifications to it. For an executable work, complete source
164     code means all the source code for all modules it contains, plus any
165     associated interface definition files, plus the scripts used to
166     control compilation and installation of the executable. However, as a
167     special exception, the source code distributed need not include
168     anything that is normally distributed (in either source or binary
169     form) with the major components (compiler, kernel, and so on) of the
170     operating system on which the executable runs, unless that component
171     itself accompanies the executable.
172    
173     If distribution of executable or object code is made by offering
174     access to copy from a designated place, then offering equivalent
175     access to copy the source code from the same place counts as
176     distribution of the source code, even though third parties are not
177     compelled to copy the source along with the object code.
178    
179     4. You may not copy, modify, sublicense, or distribute the Program
180     except as expressly provided under this License. Any attempt
181     otherwise to copy, modify, sublicense or distribute the Program is
182     void, and will automatically terminate your rights under this License.
183     However, parties who have received copies, or rights, from you under
184     this License will not have their licenses terminated so long as such
185     parties remain in full compliance.
186    
187     5. You are not required to accept this License, since you have not
188     signed it. However, nothing else grants you permission to modify or
189     distribute the Program or its derivative works. These actions are
190     prohibited by law if you do not accept this License. Therefore, by
191     modifying or distributing the Program (or any work based on the
192     Program), you indicate your acceptance of this License to do so, and
193     all its terms and conditions for copying, distributing or modifying
194     the Program or works based on it.
195    
196     6. Each time you redistribute the Program (or any work based on the
197     Program), the recipient automatically receives a license from the
198     original licensor to copy, distribute or modify the Program subject to
199     these terms and conditions. You may not impose any further
200     restrictions on the recipients' exercise of the rights granted herein.
201     You are not responsible for enforcing compliance by third parties to
202     this License.
203    
204     7. If, as a consequence of a court judgment or allegation of patent
205     infringement or for any other reason (not limited to patent issues),
206     conditions are imposed on you (whether by court order, agreement or
207     otherwise) that contradict the conditions of this License, they do not
208     excuse you from the conditions of this License. If you cannot
209     distribute so as to satisfy simultaneously your obligations under this
210     License and any other pertinent obligations, then as a consequence you
211     may not distribute the Program at all. For example, if a patent
212     license would not permit royalty-free redistribution of the Program by
213     all those who receive copies directly or indirectly through you, then
214     the only way you could satisfy both it and this License would be to
215     refrain entirely from distribution of the Program.
216    
217     If any portion of this section is held invalid or unenforceable under
218     any particular circumstance, the balance of the section is intended to
219     apply and the section as a whole is intended to apply in other
220     circumstances.
221    
222     It is not the purpose of this section to induce you to infringe any
223     patents or other property right claims or to contest validity of any
224     such claims; this section has the sole purpose of protecting the
225     integrity of the free software distribution system, which is
226     implemented by public license practices. Many people have made
227     generous contributions to the wide range of software distributed
228     through that system in reliance on consistent application of that
229     system; it is up to the author/donor to decide if he or she is willing
230     to distribute software through any other system and a licensee cannot
231     impose that choice.
232    
233     This section is intended to make thoroughly clear what is believed to
234     be a consequence of the rest of this License.
235    
236     8. If the distribution and/or use of the Program is restricted in
237     certain countries either by patents or by copyrighted interfaces, the
238     original copyright holder who places the Program under this License
239     may add an explicit geographical distribution limitation excluding
240     those countries, so that distribution is permitted only in or among
241     countries not thus excluded. In such case, this License incorporates
242     the limitation as if written in the body of this License.
243    
244     9. The Free Software Foundation may publish revised and/or new versions
245     of the General Public License from time to time. Such new versions will
246     be similar in spirit to the present version, but may differ in detail to
247     address new problems or concerns.
248    
249     Each version is given a distinguishing version number. If the Program
250     specifies a version number of this License which applies to it and "any
251     later version", you have the option of following the terms and conditions
252     either of that version or of any later version published by the Free
253     Software Foundation. If the Program does not specify a version number of
254     this License, you may choose any version ever published by the Free Software
255     Foundation.
256    
257     10. If you wish to incorporate parts of the Program into other free
258     programs whose distribution conditions are different, write to the author
259     to ask for permission. For software which is copyrighted by the Free
260     Software Foundation, write to the Free Software Foundation; we sometimes
261     make exceptions for this. Our decision will be guided by the two goals
262     of preserving the free status of all derivatives of our free software and
263     of promoting the sharing and reuse of software generally.
264    
265     NO WARRANTY
266    
267     11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
268     FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
269     OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
270     PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
271     OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
272     MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
273     TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
274     PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
275     REPAIR OR CORRECTION.
276    
277     12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
278     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
279     REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
280     INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
281     OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
282     TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
283     YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
284     PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
285     POSSIBILITY OF SUCH DAMAGES.
286    
287     END OF TERMS AND CONDITIONS
288    
289 pcg 1.2 How to Apply These Terms to Your New Programs
290 pcg 1.1
291     If you develop a new program, and you want it to be of the greatest
292     possible use to the public, the best way to achieve this is to make it
293     free software which everyone can redistribute and change under these terms.
294    
295     To do so, attach the following notices to the program. It is safest
296     to attach them to the start of each source file to most effectively
297     convey the exclusion of warranty; and each file should have at least
298     the "copyright" line and a pointer to where the full notice is found.
299    
300     <one line to give the program's name and a brief idea of what it does.>
301 pcg 1.2 Copyright (C) <year> <name of author>
302 pcg 1.1
303 pcg 1.4 This program is free software; you can redistribute it and/or modify
304 pcg 1.1 it under the terms of the GNU General Public License as published by
305     the Free Software Foundation; either version 2 of the License, or
306     (at your option) any later version.
307    
308     This program is distributed in the hope that it will be useful,
309     but WITHOUT ANY WARRANTY; without even the implied warranty of
310     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
311     GNU General Public License for more details.
312    
313     You should have received a copy of the GNU General Public License
314 pcg 1.4 along with this program; if not, write to the Free Software
315 pcg 1.2 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
316    
317 pcg 1.1
318     Also add information on how to contact you by electronic and paper mail.
319    
320     If the program is interactive, make it output a short notice like this
321     when it starts in an interactive mode:
322    
323 pcg 1.2 Gnomovision version 69, Copyright (C) year name of author
324 pcg 1.1 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
325     This is free software, and you are welcome to redistribute it
326     under certain conditions; type `show c' for details.
327    
328     The hypothetical commands `show w' and `show c' should show the appropriate
329     parts of the General Public License. Of course, the commands you use may
330     be called something other than `show w' and `show c'; they could even be
331     mouse-clicks or menu items--whatever suits your program.
332    
333     You should also get your employer (if you work as a programmer) or your
334     school, if any, to sign a "copyright disclaimer" for the program, if
335     necessary. Here is a sample; alter the names:
336    
337     Yoyodyne, Inc., hereby disclaims all copyright interest in the program
338     `Gnomovision' (which makes passes at compilers) written by James Hacker.
339    
340     <signature of Ty Coon>, 1 April 1989
341     Ty Coon, President of Vice
342    
343     This General Public License does not permit incorporating your program into
344     proprietary programs. If your program is a subroutine library, you may
345     consider it more useful to permit linking proprietary applications with the
346     library. If this is what you want to do, use the GNU Library General
347     Public License instead of this License.
