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