[d7d2da3]1FastJet is released under the terms of the GNU General Public License
2v2 (GPLv2). FastJet includes a significant body of third-party code,
3for example for third party plugin algorithms and for computational
4geometry methods. These too are usually released under the GPL or
5permissive licenses. Details are given below on a case-by-case basis.
6
7A copy of the GPLv2 is to be found at the end of this file.
8
9While the GPL license grants you considerable freedom, please bear in
10mind that FastJet's use falls under guidelines similar to those that
11are standard for Monte Carlo event generators
12(http://www.montecarlonet.org/GUIDELINES). In particular, if you use
13this code as part of work towards a scientific publication, whether
14directly or contained within another program (e.g. Delphes, SpartyJet,
15Rivet, LHC collaboration software frameworks, etc.), you should
16include a citation to
17
18 arXiv:1111.6097 (FastJet User Manual)
19 and, optionally, Phys.Lett.B641 (2006) 57 [arXiv:hep-ph/0512210]
20
21A number of other citations may also be relevant, for example for jet
22areas and subtraction, boosted object taggers, plugins and the
23underlying computational geometry methods and codes. Plugins generally
24indicate the appropriate reference in a banner. References for other
25features are to be found in the FastJet manual.

88 Dear Gregory, all,
89 after some iterations with the D0 spoke persons and other programmers who
90 have been involved in writing the C++ implementation within the D0

92
93 "As an author of the D0 Run I and D0 Run II cone code, and having
94 consulted and obtained the consent of the other authors (D0 collaboration),
95 I hereby grant you permission to distribute my/our code for the

169 GNU GENERAL PUBLIC LICENSE
170 Version 2, June 1991
171
172 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
173 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
174 Everyone is permitted to copy and distribute verbatim copies
175 of this license document, but changing it is not allowed.
176
177 Preamble
178
179 The licenses for most software are designed to take away your
180freedom to share and change it. By contrast, the GNU General Public
181License is intended to guarantee your freedom to share and change free
182software--to make sure the software is free for all its users. This
183General Public License applies to most of the Free Software
184Foundation's software and to any other program whose authors commit to
185using it. (Some other Free Software Foundation software is covered by
186the GNU Library General Public License instead.) You can apply it to
187your programs, too.
188
189 When we speak of free software, we are referring to freedom, not
190price. Our General Public Licenses are designed to make sure that you
191have the freedom to distribute copies of free software (and charge for
192this service if you wish), that you receive source code or can get it
193if you want it, that you can change the software or use pieces of it
194in new free programs; and that you know you can do these things.
195
196 To protect your rights, we need to make restrictions that forbid
197anyone to deny you these rights or to ask you to surrender the rights.
198These restrictions translate to certain responsibilities for you if you
199distribute copies of the software, or if you modify it.
200
201 For example, if you distribute copies of such a program, whether
202gratis or for a fee, you must give the recipients all the rights that
203you have. You must make sure that they, too, receive or can get the
204source code. And you must show them these terms so they know their
205rights.
206
207 We protect your rights with two steps: (1) copyright the software, and
208(2) offer you this license which gives you legal permission to copy,
209distribute and/or modify the software.
210
211 Also, for each author's protection and ours, we want to make certain
212that everyone understands that there is no warranty for this free
213software. If the software is modified by someone else and passed on, we
214want its recipients to know that what they have is not the original, so
215that any problems introduced by others will not reflect on the original
216authors' reputations.
217
218 Finally, any free program is threatened constantly by software
219patents. We wish to avoid the danger that redistributors of a free
220program will individually obtain patent licenses, in effect making the
221program proprietary. To prevent this, we have made it clear that any
222patent must be licensed for everyone's free use or not licensed at all.
223
224 The precise terms and conditions for copying, distribution and
225modification follow.
226
227 GNU GENERAL PUBLIC LICENSE
228 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
229
230 0. This License applies to any program or other work which contains
231a notice placed by the copyright holder saying it may be distributed
232under the terms of this General Public License. The "Program", below,
233refers to any such program or work, and a "work based on the Program"
234means either the Program or any derivative work under copyright law:
235that is to say, a work containing the Program or a portion of it,
236either verbatim or with modifications and/or translated into another
237language. (Hereinafter, translation is included without limitation in
238the term "modification".) Each licensee is addressed as "you".
239
240Activities other than copying, distribution and modification are not
241covered by this License; they are outside its scope. The act of
242running the Program is not restricted, and the output from the Program
243is covered only if its contents constitute a work based on the
244Program (independent of having been made by running the Program).
245Whether that is true depends on what the Program does.
246
247 1. You may copy and distribute verbatim copies of the Program's
248source code as you receive it, in any medium, provided that you
249conspicuously and appropriately publish on each copy an appropriate
250copyright notice and disclaimer of warranty; keep intact all the
251notices that refer to this License and to the absence of any warranty;
252and give any other recipients of the Program a copy of this License
253along with the Program.
254
255You may charge a fee for the physical act of transferring a copy, and
256you may at your option offer warranty protection in exchange for a fee.
257
258 2. You may modify your copy or copies of the Program or any portion
259of it, thus forming a work based on the Program, and copy and
260distribute such modifications or work under the terms of Section 1
261above, provided that you also meet all of these conditions:
262
263 a) You must cause the modified files to carry prominent notices
264 stating that you changed the files and the date of any change.
265
266 b) You must cause any work that you distribute or publish, that in
267 whole or in part contains or is derived from the Program or any
268 part thereof, to be licensed as a whole at no charge to all third
269 parties under the terms of this License.
270
271 c) If the modified program normally reads commands interactively
272 when run, you must cause it, when started running for such
273 interactive use in the most ordinary way, to print or display an
274 announcement including an appropriate copyright notice and a
275 notice that there is no warranty (or else, saying that you provide
276 a warranty) and that users may redistribute the program under
277 these conditions, and telling the user how to view a copy of this
278 License. (Exception: if the Program itself is interactive but
279 does not normally print such an announcement, your work based on
280 the Program is not required to print an announcement.)
281
282These requirements apply to the modified work as a whole. If
283identifiable sections of that work are not derived from the Program,
284and can be reasonably considered independent and separate works in
285themselves, then this License, and its terms, do not apply to those
286sections when you distribute them as separate works. But when you
287distribute the same sections as part of a whole which is a work based
288on the Program, the distribution of the whole must be on the terms of
289this License, whose permissions for other licensees extend to the
290entire whole, and thus to each and every part regardless of who wrote it.
291
292Thus, it is not the intent of this section to claim rights or contest
293your rights to work written entirely by you; rather, the intent is to
294exercise the right to control the distribution of derivative or
295collective works based on the Program.
296
297In addition, mere aggregation of another work not based on the Program
298with the Program (or with a work based on the Program) on a volume of
299a storage or distribution medium does not bring the other work under
300the scope of this License.
301
302 3. You may copy and distribute the Program (or a work based on it,
303under Section 2) in object code or executable form under the terms of
304Sections 1 and 2 above provided that you also do one of the following:
305
306 a) Accompany it with the complete corresponding machine-readable
307 source code, which must be distributed under the terms of Sections
308 1 and 2 above on a medium customarily used for software interchange; or,
309
310 b) Accompany it with a written offer, valid for at least three
311 years, to give any third party, for a charge no more than your
312 cost of physically performing source distribution, a complete
313 machine-readable copy of the corresponding source code, to be
314 distributed under the terms of Sections 1 and 2 above on a medium
315 customarily used for software interchange; or,
316
317 c) Accompany it with the information you received as to the offer
318 to distribute corresponding source code. (This alternative is
319 allowed only for noncommercial distribution and only if you
320 received the program in object code or executable form with such
321 an offer, in accord with Subsection b above.)
322
323The source code for a work means the preferred form of the work for
324making modifications to it. For an executable work, complete source
325code means all the source code for all modules it contains, plus any
326associated interface definition files, plus the scripts used to
327control compilation and installation of the executable. However, as a
328special exception, the source code distributed need not include
329anything that is normally distributed (in either source or binary
330form) with the major components (compiler, kernel, and so on) of the
331operating system on which the executable runs, unless that component
332itself accompanies the executable.
333
334If distribution of executable or object code is made by offering
335access to copy from a designated place, then offering equivalent
336access to copy the source code from the same place counts as
337distribution of the source code, even though third parties are not
338compelled to copy the source along with the object code.
339
340 4. You may not copy, modify, sublicense, or distribute the Program
341except as expressly provided under this License. Any attempt
342otherwise to copy, modify, sublicense or distribute the Program is
343void, and will automatically terminate your rights under this License.
344However, parties who have received copies, or rights, from you under
345this License will not have their licenses terminated so long as such
346parties remain in full compliance.
347
348 5. You are not required to accept this License, since you have not
349signed it. However, nothing else grants you permission to modify or
350distribute the Program or its derivative works. These actions are
351prohibited by law if you do not accept this License. Therefore, by
352modifying or distributing the Program (or any work based on the
353Program), you indicate your acceptance of this License to do so, and
354all its terms and conditions for copying, distributing or modifying
355the Program or works based on it.
356
357 6. Each time you redistribute the Program (or any work based on the
358Program), the recipient automatically receives a license from the
359original licensor to copy, distribute or modify the Program subject to
360these terms and conditions. You may not impose any further
361restrictions on the recipients' exercise of the rights granted herein.
362You are not responsible for enforcing compliance by third parties to
363this License.
364
365 7. If, as a consequence of a court judgment or allegation of patent
366infringement or for any other reason (not limited to patent issues),
367conditions are imposed on you (whether by court order, agreement or
368otherwise) that contradict the conditions of this License, they do not
369excuse you from the conditions of this License. If you cannot
370distribute so as to satisfy simultaneously your obligations under this
371License and any other pertinent obligations, then as a consequence you
372may not distribute the Program at all. For example, if a patent
373license would not permit royalty-free redistribution of the Program by
374all those who receive copies directly or indirectly through you, then
375the only way you could satisfy both it and this License would be to
376refrain entirely from distribution of the Program.
377
378If any portion of this section is held invalid or unenforceable under
379any particular circumstance, the balance of the section is intended to
380apply and the section as a whole is intended to apply in other
381circumstances.
382
383It is not the purpose of this section to induce you to infringe any
384patents or other property right claims or to contest validity of any
385such claims; this section has the sole purpose of protecting the
386integrity of the free software distribution system, which is
387implemented by public license practices. Many people have made
388generous contributions to the wide range of software distributed
389through that system in reliance on consistent application of that
390system; it is up to the author/donor to decide if he or she is willing
391to distribute software through any other system and a licensee cannot
392impose that choice.
393
394This section is intended to make thoroughly clear what is believed to
395be a consequence of the rest of this License.
396
397 8. If the distribution and/or use of the Program is restricted in
398certain countries either by patents or by copyrighted interfaces, the
399original copyright holder who places the Program under this License
400may add an explicit geographical distribution limitation excluding
401those countries, so that distribution is permitted only in or among
402countries not thus excluded. In such case, this License incorporates
403the limitation as if written in the body of this License.
404
405 9. The Free Software Foundation may publish revised and/or new versions
406of the General Public License from time to time. Such new versions will
407be similar in spirit to the present version, but may differ in detail to
408address new problems or concerns.
409
410Each version is given a distinguishing version number. If the Program
411specifies a version number of this License which applies to it and "any
412later version", you have the option of following the terms and conditions
413either of that version or of any later version published by the Free
414Software Foundation. If the Program does not specify a version number of
415this License, you may choose any version ever published by the Free Software
416Foundation.
417
418 10. If you wish to incorporate parts of the Program into other free
419programs whose distribution conditions are different, write to the author
420to ask for permission. For software which is copyrighted by the Free
421Software Foundation, write to the Free Software Foundation; we sometimes
422make exceptions for this. Our decision will be guided by the two goals
423of preserving the free status of all derivatives of our free software and
424of promoting the sharing and reuse of software generally.
425
426 NO WARRANTY
427
428 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
429FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
430OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
431PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
432OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
433MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
434TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
435PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
436REPAIR OR CORRECTION.
437
438 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
439WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
440REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
441INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
442OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
443TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
444YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
445PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
446POSSIBILITY OF SUCH DAMAGES.
447
448 END OF TERMS AND CONDITIONS
449
450 How to Apply These Terms to Your New Programs
451
452 If you develop a new program, and you want it to be of the greatest
453possible use to the public, the best way to achieve this is to make it
454free software which everyone can redistribute and change under these terms.
455
456 To do so, attach the following notices to the program. It is safest
457to attach them to the start of each source file to most effectively
458convey the exclusion of warranty; and each file should have at least
459the "copyright" line and a pointer to where the full notice is found.
460
461 <one line to give the program's name and a brief idea of what it does.>
462 Copyright (C) <year> <name of author>
463
464 This program is free software; you can redistribute it and/or modify
465 it under the terms of the GNU General Public License as published by
466 the Free Software Foundation; either version 2 of the License, or
467 (at your option) any later version.
468
469 This program is distributed in the hope that it will be useful,
470 but WITHOUT ANY WARRANTY; without even the implied warranty of
471 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
472 GNU General Public License for more details.
473
474 You should have received a copy of the GNU General Public License
475 along with this program; if not, write to the Free Software
476 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
477
478
479Also add information on how to contact you by electronic and paper mail.
480
481If the program is interactive, make it output a short notice like this
482when it starts in an interactive mode:
483
484 Gnomovision version 69, Copyright (C) year name of author
485 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
486 This is free software, and you are welcome to redistribute it
487 under certain conditions; type `show c' for details.
488
489The hypothetical commands `show w' and `show c' should show the appropriate
490parts of the General Public License. Of course, the commands you use may
491be called something other than `show w' and `show c'; they could even be
492mouse-clicks or menu items--whatever suits your program.
493
494You should also get your employer (if you work as a programmer) or your
495school, if any, to sign a "copyright disclaimer" for the program, if
496necessary. Here is a sample; alter the names:
497
498 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
499 `Gnomovision' (which makes passes at compilers) written by James Hacker.

503
504This General Public License does not permit incorporating your program into
505proprietary programs. If your program is a subroutine library, you may
506consider it more useful to permit linking proprietary applications with the
507library. If this is what you want to do, use the GNU Library General
508Public License instead of this License.
