3     Version 2, June 1991

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