10 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
11     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
12 Everyone is permitted to copy and distribute verbatim copies
13 of this license document, but changing it is not allowed.
14
15                            Preamble
16
17  The licenses for most software are designed to take away your
18freedom to share and change it.  By contrast, the GNU General Public
19License is intended to guarantee your freedom to share and change free
20software--to make sure the software is free for all its users.  This
21General Public License applies to most of the Free Software
22Foundation's software and to any other program whose authors commit to
23using it.  (Some other Free Software Foundation software is covered by
24the GNU Library General Public License instead.)  You can apply it to
25your programs, too.
26
27  When we speak of free software, we are referring to freedom, not
28price.  Our General Public Licenses are designed to make sure that you
29have the freedom to distribute copies of free software (and charge for
30this service if you wish), that you receive source code or can get it
31if you want it, that you can change the software or use pieces of it
32in new free programs; and that you know you can do these things.
33
34  To protect your rights, we need to make restrictions that forbid
35anyone to deny you these rights or to ask you to surrender the rights.
36These restrictions translate to certain responsibilities for you if you
37distribute copies of the software, or if you modify it.
38
39  For example, if you distribute copies of such a program, whether
40gratis or for a fee, you must give the recipients all the rights that
41you have.  You must make sure that they, too, receive or can get the
42source code.  And you must show them these terms so they know their
43rights.
44
45  We protect your rights with two steps: (1) copyright the software, and
46(2) offer you this license which gives you legal permission to copy,
47distribute and/or modify the software.
48
49  Also, for each author's protection and ours, we want to make certain
50that everyone understands that there is no warranty for this free
51software.  If the software is modified by someone else and passed on, we
52want its recipients to know that what they have is not the original, so
53that any problems introduced by others will not reflect on the original
54authors' reputations.
55
56  Finally, any free program is threatened constantly by software
57patents.  We wish to avoid the danger that redistributors of a free
58program will individually obtain patent licenses, in effect making the
59program proprietary.  To prevent this, we have made it clear that any
60patent must be licensed for everyone's free use or not licensed at all.
61
62  The precise terms and conditions for copying, distribution and
63modification follow.
64
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
70a notice placed by the copyright holder saying it may be distributed
71under the terms of this General Public License.  The "Program", below,
72refers to any such program or work, and a "work based on the Program"
73means either the Program or any derivative work under copyright law:
74that is to say, a work containing the Program or a portion of it,
75either verbatim or with modifications and/or translated into another
76language.  (Hereinafter, translation is included without limitation in
77the term "modification".)  Each licensee is addressed as "you".
78
79Activities other than copying, distribution and modification are not
80covered by this License; they are outside its scope.  The act of
81running the Program is not restricted, and the output from the Program
82is covered only if its contents constitute a work based on the
83Program (independent of having been made by running the Program).
84Whether that is true depends on what the Program does.
85
86  1. You may copy and distribute verbatim copies of the Program's
87source code as you receive it, in any medium, provided that you
88conspicuously and appropriately publish on each copy an appropriate
89copyright notice and disclaimer of warranty; keep intact all the
90notices that refer to this License and to the absence of any warranty;
91and give any other recipients of the Program a copy of this License
92along with the Program.
93
94You may charge a fee for the physical act of transferring a copy, and
95you 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
98of it, thus forming a work based on the Program, and copy and
99distribute such modifications or work under the terms of Section 1
100above, 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
122These requirements apply to the modified work as a whole.  If
123identifiable sections of that work are not derived from the Program,
124and can be reasonably considered independent and separate works in
125themselves, then this License, and its terms, do not apply to those
126sections when you distribute them as separate works.  But when you
127distribute the same sections as part of a whole which is a work based
128on the Program, the distribution of the whole must be on the terms of
129this License, whose permissions for other licensees extend to the
130entire whole, and thus to each and every part regardless of who wrote it.
131
132Thus, it is not the intent of this section to claim rights or contest
133your rights to work written entirely by you; rather, the intent is to
134exercise the right to control the distribution of derivative or
135collective works based on the Program.
136
137In addition, mere aggregation of another work not based on the Program
138with the Program (or with a work based on the Program) on a volume of
139a storage or distribution medium does not bring the other work under
140the scope of this License.
141
142  3. You may copy and distribute the Program (or a work based on it,
143under Section 2) in object code or executable form under the terms of
144Sections 1 and 2 above provided that you also do one of the following:
145
146    a) Accompany it with the complete corresponding machine-readable
147    source code, which must be distributed under the terms of Sections
148    1 and 2 above on a medium customarily used for software interchange; or,
149
150    b) Accompany it with a written offer, valid for at least three
151    years, to give any third party, for a charge no more than your
152    cost of physically performing source distribution, a complete
153    machine-readable copy of the corresponding source code, to be
154    distributed under the terms of Sections 1 and 2 above on a medium
155    customarily used for software interchange; or,
156
157    c) Accompany it with the information you received as to the offer
158    to distribute corresponding source code.  (This alternative is
159    allowed only for noncommercial distribution and only if you
160    received the program in object code or executable form with such
161    an offer, in accord with Subsection b above.)
162
163The source code for a work means the preferred form of the work for
164making modifications to it.  For an executable work, complete source
165code means all the source code for all modules it contains, plus any
166associated interface definition files, plus the scripts used to
167control compilation and installation of the executable.  However, as a
168special exception, the source code distributed need not include
169anything that is normally distributed (in either source or binary
170form) with the major components (compiler, kernel, and so on) of the
171operating system on which the executable runs, unless that component
172itself accompanies the executable.
173
174If distribution of executable or object code is made by offering
175access to copy from a designated place, then offering equivalent
176access to copy the source code from the same place counts as
177distribution of the source code, even though third parties are not
178compelled to copy the source along with the object code.
179
180
181  4. You may not copy, modify, sublicense, or distribute the Program
182except as expressly provided under this License.  Any attempt
183otherwise to copy, modify, sublicense or distribute the Program is
184void, and will automatically terminate your rights under this License.
185However, parties who have received copies, or rights, from you under
186this License will not have their licenses terminated so long as such
187parties remain in full compliance.
188
189  5. You are not required to accept this License, since you have not
190signed it.  However, nothing else grants you permission to modify or
191distribute the Program or its derivative works.  These actions are
192prohibited by law if you do not accept this License.  Therefore, by
193modifying or distributing the Program (or any work based on the
194Program), you indicate your acceptance of this License to do so, and
195all its terms and conditions for copying, distributing or modifying
196the Program or works based on it.
197
198  6. Each time you redistribute the Program (or any work based on the
199Program), the recipient automatically receives a license from the
200original licensor to copy, distribute or modify the Program subject to
201these terms and conditions.  You may not impose any further
202restrictions on the recipients' exercise of the rights granted herein.
203You are not responsible for enforcing compliance by third parties to
204this License.
205
206  7. If, as a consequence of a court judgment or allegation of patent
207infringement or for any other reason (not limited to patent issues),
208conditions are imposed on you (whether by court order, agreement or
209otherwise) that contradict the conditions of this License, they do not
210excuse you from the conditions of this License.  If you cannot
211distribute so as to satisfy simultaneously your obligations under this
212License and any other pertinent obligations, then as a consequence you
213may not distribute the Program at all.  For example, if a patent
214license would not permit royalty-free redistribution of the Program by
215all those who receive copies directly or indirectly through you, then
216the only way you could satisfy both it and this License would be to
217refrain entirely from distribution of the Program.
218
219If any portion of this section is held invalid or unenforceable under
220any particular circumstance, the balance of the section is intended to
221apply and the section as a whole is intended to apply in other
222circumstances.
223
224It is not the purpose of this section to induce you to infringe any
225patents or other property right claims or to contest validity of any
226such claims; this section has the sole purpose of protecting the
227integrity of the free software distribution system, which is
228implemented by public license practices.  Many people have made
229generous contributions to the wide range of software distributed
230through that system in reliance on consistent application of that
231system; it is up to the author/donor to decide if he or she is willing
232to distribute software through any other system and a licensee cannot
233impose that choice.
234
235This section is intended to make thoroughly clear what is believed to
236be a consequence of the rest of this License.
237
238
239  8. If the distribution and/or use of the Program is restricted in
240certain countries either by patents or by copyrighted interfaces, the
241original copyright holder who places the Program under this License
242may add an explicit geographical distribution limitation excluding
243those countries, so that distribution is permitted only in or among
244countries not thus excluded.  In such case, this License incorporates
245the limitation as if written in the body of this License.
246
247  9. The Free Software Foundation may publish revised and/or new versions
248of the General Public License from time to time.  Such new versions will
249be similar in spirit to the present version, but may differ in detail to
250address new problems or concerns.
251
252Each version is given a distinguishing version number.  If the Program
253specifies a version number of this License which applies to it and "any
254later version", you have the option of following the terms and conditions
255either of that version or of any later version published by the Free
256Software Foundation.  If the Program does not specify a version number of
257this License, you may choose any version ever published by the Free Software
258Foundation.
259
260  10. If you wish to incorporate parts of the Program into other free
261programs whose distribution conditions are different, write to the author
262to ask for permission.  For software which is copyrighted by the Free
263Software Foundation, write to the Free Software Foundation; we sometimes
264make exceptions for this.  Our decision will be guided by the two goals
265of preserving the free status of all derivatives of our free software and
266of promoting the sharing and reuse of software generally.
267
268                            NO WARRANTY
269
270  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
271FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
272OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
273PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
274OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
275MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
276TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
277PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
278REPAIR OR CORRECTION.
279
280  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
281WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
282REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
283INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
284OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
285TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
286YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
287PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
288POSSIBILITY OF SUCH DAMAGES.
289
290                     END OF TERMS AND CONDITIONS
291
292
293            How to Apply These Terms to Your New Programs
294
295  If you develop a new program, and you want it to be of the greatest
296possible use to the public, the best way to achieve this is to make it
297free software which everyone can redistribute and change under these terms.
298
299  To do so, attach the following notices to the program.  It is safest
300to attach them to the start of each source file to most effectively
301convey the exclusion of warranty; and each file should have at least
302the "copyright" line and a pointer to where the full notice is found.
303
304    <one line to give the program's name and a brief idea of what it does.>
305    Copyright (C) <year>  <name of author>
306
307    This program is free software; you can redistribute it and/or modify
308    it under the terms of the GNU General Public License as published by
309    the Free Software Foundation; either version 2 of the License, or
310    (at your option) any later version.
311
312    This program is distributed in the hope that it will be useful,
313    but WITHOUT ANY WARRANTY; without even the implied warranty of
314    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
315    GNU General Public License for more details.
316
317    You should have received a copy of the GNU General Public License
318    along with this program; if not, write to the Free Software
319    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
320
321
322Also add information on how to contact you by electronic and paper mail.
323
324If the program is interactive, make it output a short notice like this
325when it starts in an interactive mode:
326
327    Gnomovision version 69, Copyright (C) year  name of author
328    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
329    This is free software, and you are welcome to redistribute it
330    under certain conditions; type `show c' for details.
331
332The hypothetical commands `show w' and `show c' should show the appropriate
333parts of the General Public License.  Of course, the commands you use may
334be called something other than `show w' and `show c'; they could even be
335mouse-clicks or menu items--whatever suits your program.
336
337You should also get your employer (if you work as a programmer) or your
338school, if any, to sign a "copyright disclaimer" for the program, if
339necessary.  Here is a sample; alter the names:
340
341  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
342  `Gnomovision' (which makes passes at compilers) written by James Hacker.
343
344  <signature of Ty Coon>, 1 April 1989
345  Ty Coon, President of Vice
346
347This General Public License does not permit incorporating your program into
348proprietary programs.  If your program is a subroutine library, you may
349consider it more useful to permit linking proprietary applications with the
350library.  If this is what you want to do, use the GNU Library General
351Public License instead of this License.
