044: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
045: Everyone is permitted to copy and distribute verbatim copies
046: of this license document, but changing it is not allowed.
047:
048:                             Preamble
049:
050:   The licenses for most software are designed to take away your
051: freedom to share and change it.  By contrast, the GNU General Public
052: License is intended to guarantee your freedom to share and change free
053: software--to make sure the software is free for all its users.  This
054: General Public License applies to most of the Free Software
055: Foundation's software and to any other program whose authors commit to
056: using it.  (Some other Free Software Foundation software is covered by
057: the GNU Lesser General Public License instead.)  You can apply it to
058: your programs, too.
059:
060:   When we speak of free software, we are referring to freedom, not
061: price.  Our General Public Licenses are designed to make sure that you
062: have the freedom to distribute copies of free software (and charge for
063: this service if you wish), that you receive source code or can get it
064: if you want it, that you can change the software or use pieces of it
065: in new free programs; and that you know you can do these things.
066:
067:   To protect your rights, we need to make restrictions that forbid
068: anyone to deny you these rights or to ask you to surrender the rights.
069: These restrictions translate to certain responsibilities for you if you
070: distribute copies of the software, or if you modify it.
071:
072:   For example, if you distribute copies of such a program, whether
073: gratis or for a fee, you must give the recipients all the rights that
074: you have.  You must make sure that they, too, receive or can get the
075: source code.  And you must show them these terms so they know their
076: rights.
077:
078:   We protect your rights with two steps: (1) copyright the software, and
079: (2) offer you this license which gives you legal permission to copy,
080: distribute and/or modify the software.
081:
082:   Also, for each author's protection and ours, we want to make certain
083: that everyone understands that there is no warranty for this free
084: software.  If the software is modified by someone else and passed on, we
085: want its recipients to know that what they have is not the original, so
086: that any problems introduced by others will not reflect on the original
087: authors' reputations.
088:
089:   Finally, any free program is threatened constantly by software
090: patents.  We wish to avoid the danger that redistributors of a free
091: program will individually obtain patent licenses, in effect making the
092: program proprietary.  To prevent this, we have made it clear that any
093: patent must be licensed for everyone's free use or not licensed at all.
094:
095:   The precise terms and conditions for copying, distribution and
096: modification follow.
097:
098:                     GNU GENERAL PUBLIC LICENSE
099:    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
100:
101:   0. This License applies to any program or other work which contains
102: a notice placed by the copyright holder saying it may be distributed
103: under the terms of this General Public License.  The "Program", below,
104: refers to any such program or work, and a "work based on the Program"
105: means either the Program or any derivative work under copyright law:
106: that is to say, a work containing the Program or a portion of it,
107: either verbatim or with modifications and/or translated into another
108: language.  (Hereinafter, translation is included without limitation in
109: the term "modification".)  Each licensee is addressed as "you".
110:
111: Activities other than copying, distribution and modification are not
112: covered by this License; they are outside its scope.  The act of
113: running the Program is not restricted, and the output from the Program
114: is covered only if its contents constitute a work based on the
115: Program (independent of having been made by running the Program).
116: Whether that is true depends on what the Program does.
117:
118:   1. You may copy and distribute verbatim copies of the Program's
119: source code as you receive it, in any medium, provided that you
120: conspicuously and appropriately publish on each copy an appropriate
121: copyright notice and disclaimer of warranty; keep intact all the
122: notices that refer to this License and to the absence of any warranty;
123: and give any other recipients of the Program a copy of this License
124: along with the Program.
125:
126: You may charge a fee for the physical act of transferring a copy, and
127: you may at your option offer warranty protection in exchange for a fee.
128:
129:   2. You may modify your copy or copies of the Program or any portion
130: of it, thus forming a work based on the Program, and copy and
131: distribute such modifications or work under the terms of Section 1
132: above, provided that you also meet all of these conditions:
133:
134:     a) You must cause the modified files to carry prominent notices
135:     stating that you changed the files and the date of any change.
136:
137:     b) You must cause any work that you distribute or publish, that in
138:     whole or in part contains or is derived from the Program or any
139:     part thereof, to be licensed as a whole at no charge to all third
140:     parties under the terms of this License.
141:
142:     c) If the modified program normally reads commands interactively
143:     when run, you must cause it, when started running for such
144:     interactive use in the most ordinary way, to print or display an
145:     announcement including an appropriate copyright notice and a
146:     notice that there is no warranty (or else, saying that you provide
147:     a warranty) and that users may redistribute the program under
148:     these conditions, and telling the user how to view a copy of this
149:     License.  (Exception: if the Program itself is interactive but
150:     does not normally print such an announcement, your work based on
151:     the Program is not required to print an announcement.)
152:
153: These requirements apply to the modified work as a whole.  If
154: identifiable sections of that work are not derived from the Program,
155: and can be reasonably considered independent and separate works in
156: themselves, then this License, and its terms, do not apply to those
157: sections when you distribute them as separate works.  But when you
158: distribute the same sections as part of a whole which is a work based
159: on the Program, the distribution of the whole must be on the terms of
160: this License, whose permissions for other licensees extend to the
161: entire whole, and thus to each and every part regardless of who wrote it.
162:
163: Thus, it is not the intent of this section to claim rights or contest
164: your rights to work written entirely by you; rather, the intent is to
165: exercise the right to control the distribution of derivative or
166: collective works based on the Program.
167:
168: In addition, mere aggregation of another work not based on the Program
169: with the Program (or with a work based on the Program) on a volume of
170: a storage or distribution medium does not bring the other work under
171: the scope of this License.
172:
173:   3. You may copy and distribute the Program (or a work based on it,
174: under Section 2) in object code or executable form under the terms of
175: Sections 1 and 2 above provided that you also do one of the following:
176:
177:     a) Accompany it with the complete corresponding machine-readable
178:     source code, which must be distributed under the terms of Sections
179:     1 and 2 above on a medium customarily used for software interchange; or,
180:
181:     b) Accompany it with a written offer, valid for at least three
182:     years, to give any third party, for a charge no more than your
183:     cost of physically performing source distribution, a complete
184:     machine-readable copy of the corresponding source code, to be
185:     distributed under the terms of Sections 1 and 2 above on a medium
186:     customarily used for software interchange; or,
187:
188:     c) Accompany it with the information you received as to the offer
189:     to distribute corresponding source code.  (This alternative is
190:     allowed only for noncommercial distribution and only if you
191:     received the program in object code or executable form with such
192:     an offer, in accord with Subsection b above.)
193:
194: The source code for a work means the preferred form of the work for
195: making modifications to it.  For an executable work, complete source
196: code means all the source code for all modules it contains, plus any
197: associated interface definition files, plus the scripts used to
198: control compilation and installation of the executable.  However, as a
199: special exception, the source code distributed need not include
200: anything that is normally distributed (in either source or binary
201: form) with the major components (compiler, kernel, and so on) of the
202: operating system on which the executable runs, unless that component
203: itself accompanies the executable.
204:
205: If distribution of executable or object code is made by offering
206: access to copy from a designated place, then offering equivalent
207: access to copy the source code from the same place counts as
208: distribution of the source code, even though third parties are not
209: compelled to copy the source along with the object code.
210:
211:   4. You may not copy, modify, sublicense, or distribute the Program
212: except as expressly provided under this License.  Any attempt
213: otherwise to copy, modify, sublicense or distribute the Program is
214: void, and will automatically terminate your rights under this License.
215: However, parties who have received copies, or rights, from you under
216: this License will not have their licenses terminated so long as such
217: parties remain in full compliance.
218:
219:   5. You are not required to accept this License, since you have not
220: signed it.  However, nothing else grants you permission to modify or
221: distribute the Program or its derivative works.  These actions are
222: prohibited by law if you do not accept this License.  Therefore, by
223: modifying or distributing the Program (or any work based on the
224: Program), you indicate your acceptance of this License to do so, and
225: all its terms and conditions for copying, distributing or modifying
226: the Program or works based on it.
227:
228:   6. Each time you redistribute the Program (or any work based on the
229: Program), the recipient automatically receives a license from the
230: original licensor to copy, distribute or modify the Program subject to
231: these terms and conditions.  You may not impose any further
232: restrictions on the recipients' exercise of the rights granted herein.
233: You are not responsible for enforcing compliance by third parties to
234: this License.
235:
236:   7. If, as a consequence of a court judgment or allegation of patent
237: infringement or for any other reason (not limited to patent issues),
238: conditions are imposed on you (whether by court order, agreement or
239: otherwise) that contradict the conditions of this License, they do not
240: excuse you from the conditions of this License.  If you cannot
241: distribute so as to satisfy simultaneously your obligations under this
242: License and any other pertinent obligations, then as a consequence you
243: may not distribute the Program at all.  For example, if a patent
244: license would not permit royalty-free redistribution of the Program by
245: all those who receive copies directly or indirectly through you, then
246: the only way you could satisfy both it and this License would be to
247: refrain entirely from distribution of the Program.
248:
249: If any portion of this section is held invalid or unenforceable under
250: any particular circumstance, the balance of the section is intended to
251: apply and the section as a whole is intended to apply in other
252: circumstances.
253:
254: It is not the purpose of this section to induce you to infringe any
255: patents or other property right claims or to contest validity of any
256: such claims; this section has the sole purpose of protecting the
257: integrity of the free software distribution system, which is
258: implemented by public license practices.  Many people have made
259: generous contributions to the wide range of software distributed
260: through that system in reliance on consistent application of that
261: system; it is up to the author/donor to decide if he or she is willing
262: to distribute software through any other system and a licensee cannot
263: impose that choice.
264:
265: This section is intended to make thoroughly clear what is believed to
266: be a consequence of the rest of this License.
267:
268:   8. If the distribution and/or use of the Program is restricted in
269: certain countries either by patents or by copyrighted interfaces, the
270: original copyright holder who places the Program under this License
271: may add an explicit geographical distribution limitation excluding
272: those countries, so that distribution is permitted only in or among
273: countries not thus excluded.  In such case, this License incorporates
274: the limitation as if written in the body of this License.
275:
276:   9. The Free Software Foundation may publish revised and/or new versions
277: of the General Public License from time to time.  Such new versions will
278: be similar in spirit to the present version, but may differ in detail to
279: address new problems or concerns.
280:
281: Each version is given a distinguishing version number.  If the Program
282: specifies a version number of this License which applies to it and "any
283: later version", you have the option of following the terms and conditions
284: either of that version or of any later version published by the Free
285: Software Foundation.  If the Program does not specify a version number of
286: this License, you may choose any version ever published by the Free Software
287: Foundation.
288:
289:   10. If you wish to incorporate parts of the Program into other free
290: programs whose distribution conditions are different, write to the author
291: to ask for permission.  For software which is copyrighted by the Free
292: Software Foundation, write to the Free Software Foundation; we sometimes
293: make exceptions for this.  Our decision will be guided by the two goals
294: of preserving the free status of all derivatives of our free software and
295: of promoting the sharing and reuse of software generally.
296:
297:                             NO WARRANTY
298:
299:   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
300: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
301: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
302: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
303: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
304: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
305: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
306: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
307: REPAIR OR CORRECTION.
308:
309:   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
310: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
311: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
312: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
313: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
314: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
315: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
316: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
317: POSSIBILITY OF SUCH DAMAGES.
318:
319:                      END OF TERMS AND CONDITIONS
320:
321:             How to Apply These Terms to Your New Programs
322:
323:   If you develop a new program, and you want it to be of the greatest
324: possible use to the public, the best way to achieve this is to make it
325: free software which everyone can redistribute and change under these terms.
326:
327:   To do so, attach the following notices to the program.  It is safest
328: to attach them to the start of each source file to most effectively
329: convey the exclusion of warranty; and each file should have at least
330: the "copyright" line and a pointer to where the full notice is found.
331:
332:     <one line to give the program's name and a brief idea of what it does.>
333:     Copyright (C) <year>  <name of author>
334:
335:     This program is free software; you can redistribute it and/or modify
336:     it under the terms of the GNU General Public License as published by
337:     the Free Software Foundation; either version 2 of the License, or
338:     (at your option) any later version.
339:
340:     This program is distributed in the hope that it will be useful,
341:     but WITHOUT ANY WARRANTY; without even the implied warranty of
342:     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
343:     GNU General Public License for more details.
344:
345:     You should have received a copy of the GNU General Public License along
346:     with this program; if not, write to the Free Software Foundation, Inc.,
347:     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
348:
349: Also add information on how to contact you by electronic and paper mail.
350:
351: If the program is interactive, make it output a short notice like this
352: when it starts in an interactive mode:
353:
354:     Gnomovision version 69, Copyright (C) year name of author
355:     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
356:     This is free software, and you are welcome to redistribute it
357:     under certain conditions; type `show c' for details.
358:
359: The hypothetical commands `show w' and `show c' should show the appropriate
360: parts of the General Public License.  Of course, the commands you use may
361: be called something other than `show w' and `show c'; they could even be
362: mouse-clicks or menu items--whatever suits your program.
363:
364: You should also get your employer (if you work as a programmer) or your
365: school, if any, to sign a "copyright disclaimer" for the program, if
366: necessary.  Here is a sample; alter the names:
367:
368:   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
369:   `Gnomovision' (which makes passes at compilers) written by James Hacker.
370:
371:   <signature of Ty Coon>, 1 April 1989
372:   Ty Coon, President of Vice
373:
374: This General Public License does not permit incorporating your program into
375: proprietary programs.  If your program is a subroutine library, you may
376: consider it more useful to permit linking proprietary applications with the
377: library.  If this is what you want to do, use the GNU Lesser General
378: Public License instead of this License.
