6                       51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
7 Everyone is permitted to copy and distribute verbatim copies
8 of this license document, but changing it is not allowed.

10          Preamble
11
12  The licenses for most software are designed to take away your
13freedom to share and change it.  By contrast, the GNU General Public
14License is intended to guarantee your freedom to share and change free
15software--to make sure the software is free for all its users.  This
16General Public License applies to most of the Free Software
17Foundation's software and to any other program whose authors commit to
18using it.  (Some other Free Software Foundation software is covered by
19the GNU Library General Public License instead.)  You can apply it to
20your programs, too.
21
22  When we speak of free software, we are referring to freedom, not
23price.  Our General Public Licenses are designed to make sure that you
24have the freedom to distribute copies of free software (and charge for
25this service if you wish), that you receive source code or can get it
26if you want it, that you can change the software or use pieces of it
27in 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
30anyone to deny you these rights or to ask you to surrender the rights.
31These restrictions translate to certain responsibilities for you if you
32distribute copies of the software, or if you modify it.
33
34  For example, if you distribute copies of such a program, whether
35gratis or for a fee, you must give the recipients all the rights that
36you have.  You must make sure that they, too, receive or can get the
37source code.  And you must show them these terms so they know their
38rights.
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,
42distribute and/or modify the software.
43
44  Also, for each author's protection and ours, we want to make certain
45that everyone understands that there is no warranty for this free
46software.  If the software is modified by someone else and passed on, we
47want its recipients to know that what they have is not the original, so
48that any problems introduced by others will not reflect on the original
49authors' reputations.
50
51  Finally, any free program is threatened constantly by software
52patents.  We wish to avoid the danger that redistributors of a free
53program will individually obtain patent licenses, in effect making the
54program proprietary.  To prevent this, we have made it clear that any
55patent must be licensed for everyone's free use or not licensed at all.
56
57  The precise terms and conditions for copying, distribution and
58modification 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
64a notice placed by the copyright holder saying it may be distributed
65under the terms of this General Public License.  The "Program", below,
66refers to any such program or work, and a "work based on the Program"
67means either the Program or any derivative work under copyright law:
68that is to say, a work containing the Program or a portion of it,
69either verbatim or with modifications and/or translated into another
70language.  (Hereinafter, translation is included without limitation in
71the term "modification".)  Each licensee is addressed as "you".
72
73Activities other than copying, distribution and modification are not
74covered by this License; they are outside its scope.  The act of
75running the Program is not restricted, and the output from the Program
76is covered only if its contents constitute a work based on the
77Program (independent of having been made by running the Program).
78Whether that is true depends on what the Program does.
79
80  1. You may copy and distribute verbatim copies of the Program's
81source code as you receive it, in any medium, provided that you
82conspicuously and appropriately publish on each copy an appropriate
83copyright notice and disclaimer of warranty; keep intact all the
84notices that refer to this License and to the absence of any warranty;
85and give any other recipients of the Program a copy of this License
86along with the Program.
87
88You may charge a fee for the physical act of transferring a copy, and
89you 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
92of it, thus forming a work based on the Program, and copy and
93distribute such modifications or work under the terms of Section 1
94above, 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
115These requirements apply to the modified work as a whole.  If
116identifiable sections of that work are not derived from the Program,
117and can be reasonably considered independent and separate works in
118themselves, then this License, and its terms, do not apply to those
119sections when you distribute them as separate works.  But when you
120distribute the same sections as part of a whole which is a work based
121on the Program, the distribution of the whole must be on the terms of
122this License, whose permissions for other licensees extend to the
123entire whole, and thus to each and every part regardless of who wrote it.
124
125Thus, it is not the intent of this section to claim rights or contest
126your rights to work written entirely by you; rather, the intent is to
127exercise the right to control the distribution of derivative or
128collective works based on the Program.
129
130In addition, mere aggregation of another work not based on the Program
131with the Program (or with a work based on the Program) on a volume of
132a storage or distribution medium does not bring the other work under
133the scope of this License.
134
135  3. You may copy and distribute the Program (or a work based on it,
136under Section 2) in object code or executable form under the terms of
137Sections 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
142    interchange; or,
143
144    b) Accompany it with a written offer, valid for at least three
145    years, to give any third party, for a charge no more than your
146    cost of physically performing source distribution, a complete
147    machine-readable copy of the corresponding source code, to be
148    distributed under the terms of Sections 1 and 2 above on a medium
149    customarily used for software interchange; or,
150
151    c) Accompany it with the information you received as to the offer
152    to distribute corresponding source code.  (This alternative is
153    allowed only for noncommercial distribution and only if you
154    received the program in object code or executable form with such
155    an offer, in accord with Subsection b above.)
156
157The source code for a work means the preferred form of the work for
158making modifications to it.  For an executable work, complete source
159code means all the source code for all modules it contains, plus any
160associated interface definition files, plus the scripts used to
161control compilation and installation of the executable.  However, as a
162special exception, the source code distributed need not include
163anything that is normally distributed (in either source or binary
164form) with the major components (compiler, kernel, and so on) of the
165operating system on which the executable runs, unless that component
166itself accompanies the executable.
167
168If distribution of executable or object code is made by offering
169access to copy from a designated place, then offering equivalent
170access to copy the source code from the same place counts as
171distribution of the source code, even though third parties are not
172compelled to copy the source along with the object code.
173
174  4. You may not copy, modify, sublicense, or distribute the Program
175except as expressly provided under this License.  Any attempt
176otherwise to copy, modify, sublicense or distribute the Program is
177void, and will automatically terminate your rights under this License.
178However, parties who have received copies, or rights, from you under
179this License will not have their licenses terminated so long as such
180parties remain in full compliance.
181
182  5. You are not required to accept this License, since you have not
183signed it.  However, nothing else grants you permission to modify or
184distribute the Program or its derivative works.  These actions are
185prohibited by law if you do not accept this License.  Therefore, by
186modifying or distributing the Program (or any work based on the
187Program), you indicate your acceptance of this License to do so, and
188all its terms and conditions for copying, distributing or modifying
189the Program or works based on it.
190
191  6. Each time you redistribute the Program (or any work based on the
192Program), the recipient automatically receives a license from the
193original licensor to copy, distribute or modify the Program subject to
194these terms and conditions.  You may not impose any further
195restrictions on the recipients' exercise of the rights granted herein.
196You are not responsible for enforcing compliance by third parties to
197this License.
198
199  7. If, as a consequence of a court judgment or allegation of patent
200infringement or for any other reason (not limited to patent issues),
201conditions are imposed on you (whether by court order, agreement or
202otherwise) that contradict the conditions of this License, they do not
203excuse you from the conditions of this License.  If you cannot
204distribute so as to satisfy simultaneously your obligations under this
205License and any other pertinent obligations, then as a consequence you
206may not distribute the Program at all.  For example, if a patent
207license would not permit royalty-free redistribution of the Program by
208all those who receive copies directly or indirectly through you, then
209the only way you could satisfy both it and this License would be to
210refrain entirely from distribution of the Program.
211
212If any portion of this section is held invalid or unenforceable under
213any particular circumstance, the balance of the section is intended to
214apply and the section as a whole is intended to apply in other
215circumstances.
216
217It is not the purpose of this section to induce you to infringe any
218patents or other property right claims or to contest validity of any
219such claims; this section has the sole purpose of protecting the
220integrity of the free software distribution system, which is
221implemented by public license practices.  Many people have made
222generous contributions to the wide range of software distributed
223through that system in reliance on consistent application of that
224system; it is up to the author/donor to decide if he or she is willing
225to distribute software through any other system and a licensee cannot
226impose that choice.
227
228This section is intended to make thoroughly clear what is believed to
229be a consequence of the rest of this License.
230
231  8. If the distribution and/or use of the Program is restricted in
232certain countries either by patents or by copyrighted interfaces, the
233original copyright holder who places the Program under this License
234may add an explicit geographical distribution limitation excluding
235those countries, so that distribution is permitted only in or among
236countries not thus excluded.  In such case, this License incorporates
237the limitation as if written in the body of this License.
238
239  9. The Free Software Foundation may publish revised and/or new versions
240of the General Public License from time to time.  Such new versions will
241be similar in spirit to the present version, but may differ in detail to
242address new problems or concerns.
243
244Each version is given a distinguishing version number.  If the Program
245specifies a version number of this License which applies to it and
246"any later version", you have the option of following the terms and
247conditions either of that version or of any later version published by
248the Free Software Foundation.  If the Program does not specify a
249version number of this License, you may choose any version ever
250published by the Free Software Foundation.
251
252  10. If you wish to incorporate parts of the Program into other free
253programs whose distribution conditions are different, write to the author
254to ask for permission.  For software which is copyrighted by the Free
255Software Foundation, write to the Free Software Foundation; we sometimes
256make exceptions for this.  Our decision will be guided by the two goals
257of preserving the free status of all derivatives of our free software and
258of promoting the sharing and reuse of software generally.
259
260          NO WARRANTY
261
262  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
263WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
264EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
265OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY
266KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
267IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
268PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
269PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
270THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
271
272  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
273WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
274AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
275FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
276CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
277PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
278RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
279FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
280SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
281DAMAGES.
282
283         END OF TERMS AND CONDITIONS
284
285      How to Apply These Terms to Your New Programs
286
287  If you develop a new program, and you want it to be of the greatest
288possible use to the public, the best way to achieve this is to make it
289free software which everyone can redistribute and change under these
290terms.
291
292  To do so, attach the following notices to the program.  It is safest
293to attach them to the start of each source file to most effectively
294convey the exclusion of warranty; and each file should have at least
295the "copyright" line and a pointer to where the full notice is found.
296
297    <one line to give the program's name and a brief idea of what it does.>
298    Copyright (C) <year>  <name of author>
299
300    This program is free software; you can redistribute it and/or modify
301    it under the terms of the GNU General Public License as published by
302    the Free Software Foundation; either version 2 of the License, or
303    (at your option) any later version.
304
305    This program is distributed in the hope that it will be useful,
306    but WITHOUT ANY WARRANTY; without even the implied warranty of
307    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
308    GNU General Public License for more details.
309
310    You should have received a copy of the GNU General Public License
311    along with this program; if not, write to the Free Software
312    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
313
314
315Also add information on how to contact you by electronic and paper mail.
316
317If the program is interactive, make it output a short notice like this
318when it starts in an interactive mode:
319
320    Gnomovision version 69, Copyright (C) year name of author
321    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
322    This is free software, and you are welcome to redistribute it
323    under certain conditions; type `show c' for details.
324
325The hypothetical commands `show w' and `show c' should show the appropriate
326parts of the General Public License.  Of course, the commands you use may
327be called something other than `show w' and `show c'; they could even be
328mouse-clicks or menu items--whatever suits your program.
329
330You should also get your employer (if you work as a programmer) or your
331school, if any, to sign a "copyright disclaimer" for the program, if
332necessary.  Here is a sample; alter the names:
333
334  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
335  `Gnomovision' (which makes passes at compilers) written by James Hacker.
336
337  <signature of Ty Coon>, 1 April 1989
338  Ty Coon, President of Vice
339
340This General Public License does not permit incorporating your program into
341proprietary programs.  If your program is a subroutine library, you may
342consider it more useful to permit linking proprietary applications with the
343library.  If this is what you want to do, use the GNU Library General
344Public License instead of this License.
