  1The General Public License (GPL)
  2Version 2, June 1991
  3
  4Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
  5Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
  6verbatim copies of this license document, but changing it is not allowed.

  8Preamble
  9
 10The licenses for most software are designed to take away your freedom to share
 11and change it. By contrast, the GNU General Public License is intended to
 12guarantee your freedom to share and change free software--to make sure the
 13software is free for all its users. This General Public License applies to most of
 14the Free Software Foundation's software and to any other program whose
 15authors commit to using it. (Some other Free Software Foundation software is
 16covered by the GNU Library General Public License instead.) You can apply it to
 17your programs, too.
 18
 19When we speak of free software, we are referring to freedom, not price. Our
 20General Public Licenses are designed to make sure that you have the freedom
 21to distribute copies of free software (and charge for this service if you wish), that
 22you receive source code or can get it if you want it, that you can change the
 23software or use pieces of it in new free programs; and that you know you can do
 24these things.
 25
 26To protect your rights, we need to make restrictions that forbid anyone to deny
 27you these rights or to ask you to surrender the rights. These restrictions
 28translate to certain responsibilities for you if you distribute copies of the
 29software, or if you modify it.
 30
 31For example, if you distribute copies of such a program, whether gratis or for a
 32fee, you must give the recipients all the rights that you have. You must make
 33sure that they, too, receive or can get the source code. And you must show
 34them these terms so they know their rights.
 35
 36We protect your rights with two steps: (1) copyright the software, and (2) offer
 37you this license which gives you legal permission to copy, distribute and/or
 38modify the software.
 39
 40Also, for each author's protection and ours, we want to make certain that
 41everyone understands that there is no warranty for this free software. If the
 42software is modified by someone else and passed on, we want its recipients to
 43know that what they have is not the original, so that any problems introduced by
 44others will not reflect on the original authors' reputations.
 45
 46Finally, any free program is threatened constantly by software patents. We wish
 47to avoid the danger that redistributors of a free program will individually obtain
 48patent licenses, in effect making the program proprietary. To prevent this, we
 49have made it clear that any patent must be licensed for everyone's free use or
 50not licensed at all.
 51
 52The precise terms and conditions for copying, distribution and modification
 53follow.
 54
 55GNU GENERAL PUBLIC LICENSE
 56TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
 57MODIFICATION
 58
 590. This License applies to any program or other work which contains a notice
 60placed by the copyright holder saying it may be distributed under the terms of
 61this General Public License. The "Program", below, refers to any such program
 62or work, and a "work based on the Program" means either the Program or any
 63derivative work under copyright law: that is to say, a work containing the
 64Program or a portion of it, either verbatim or with modifications and/or translated
 65into another language. (Hereinafter, translation is included without limitation in
 66the term "modification".) Each licensee is addressed as "you".
 67
 68Activities other than copying, distribution and modification are not covered by
 69this License; they are outside its scope. The act of running the Program is not
 70restricted, and the output from the Program is covered only if its contents
 71constitute a work based on the Program (independent of having been made by
 72running the Program). Whether that is true depends on what the Program does.
 73
 741. You may copy and distribute verbatim copies of the Program's source code as
 75you receive it, in any medium, provided that you conspicuously and appropriately
 76publish on each copy an appropriate copyright notice and disclaimer of warranty;
 77keep intact all the notices that refer to this License and to the absence of any
 78warranty; and give any other recipients of the Program a copy of this License
 79along with the Program.
 80
 81You may charge a fee for the physical act of transferring a copy, and you may at
 82your option offer warranty protection in exchange for a fee.
 83
 842. You may modify your copy or copies of the Program or any portion of it, thus
 85forming a work based on the Program, and copy and distribute such
 86modifications or work under the terms of Section 1 above, provided that you also
 87meet all of these conditions:
 88
 89a) You must cause the modified files to carry prominent notices stating that you
 90changed the files and the date of any change.
 91
 92b) You must cause any work that you distribute or publish, that in whole or in
 93part contains or is derived from the Program or any part thereof, to be licensed
 94as a whole at no charge to all third parties under the terms of this License.
 95
 96c) If the modified program normally reads commands interactively when run, you
 97must cause it, when started running for such interactive use in the most ordinary
 98way, to print or display an announcement including an appropriate copyright
 99notice and a notice that there is no warranty (or else, saying that you provide a
100warranty) and that users may redistribute the program under these conditions,
101and telling the user how to view a copy of this License. (Exception: if the
102Program itself is interactive but does not normally print such an announcement,
103your work based on the Program is not required to print an announcement.)
104
105These requirements apply to the modified work as a whole. If identifiable
106sections of that work are not derived from the Program, and can be reasonably
107considered independent and separate works in themselves, then this License,
108and its terms, do not apply to those sections when you distribute them as
109separate works. But when you distribute the same sections as part of a whole
110which is a work based on the Program, the distribution of the whole must be on
111the terms of this License, whose permissions for other licensees extend to the
112entire whole, and thus to each and every part regardless of who wrote it.
113
114Thus, it is not the intent of this section to claim rights or contest your rights to
115work written entirely by you; rather, the intent is to exercise the right to control
116the distribution of derivative or collective works based on the Program.
117
118In addition, mere aggregation of another work not based on the Program with the
119Program (or with a work based on the Program) on a volume of a storage or
120distribution medium does not bring the other work under the scope of this
121License.
122
1233. You may copy and distribute the Program (or a work based on it, under
124Section 2) in object code or executable form under the terms of Sections 1 and 2
125above provided that you also do one of the following:
126
127a) Accompany it with the complete corresponding machine-readable source
128code, which must be distributed under the terms of Sections 1 and 2 above on a
129medium customarily used for software interchange; or,
130
131b) Accompany it with a written offer, valid for at least three years, to give any
132third party, for a charge no more than your cost of physically performing source
133distribution, a complete machine-readable copy of the corresponding source
134code, to be distributed under the terms of Sections 1 and 2 above on a medium
135customarily used for software interchange; or,
136
137c) Accompany it with the information you received as to the offer to distribute
138corresponding source code. (This alternative is allowed only for noncommercial
139distribution and only if you received the program in object code or executable
140form with such an offer, in accord with Subsection b above.)
141
142The source code for a work means the preferred form of the work for making
143modifications to it. For an executable work, complete source code means all the
144source code for all modules it contains, plus any associated interface definition
145files, plus the scripts used to control compilation and installation of the
146executable. However, as a special exception, the source code distributed need
147not include anything that is normally distributed (in either source or binary form)
148with the major components (compiler, kernel, and so on) of the operating system
149on which the executable runs, unless that component itself accompanies the
150executable.
151
152If distribution of executable or object code is made by offering access to copy
153from a designated place, then offering equivalent access to copy the source
154code from the same place counts as distribution of the source code, even though
155third parties are not compelled to copy the source along with the object code.
156
1574. You may not copy, modify, sublicense, or distribute the Program except as
158expressly provided under this License. Any attempt otherwise to copy, modify,
159sublicense or distribute the Program is void, and will automatically terminate
160your rights under this License. However, parties who have received copies, or
161rights, from you under this License will not have their licenses terminated so long
162as such parties remain in full compliance.
163
1645. You are not required to accept this License, since you have not signed it.
165However, nothing else grants you permission to modify or distribute the Program
166or its derivative works. These actions are prohibited by law if you do not accept
167this License. Therefore, by modifying or distributing the Program (or any work
168based on the Program), you indicate your acceptance of this License to do so,
169and all its terms and conditions for copying, distributing or modifying the
170Program or works based on it.
171
1726. Each time you redistribute the Program (or any work based on the Program),
173the recipient automatically receives a license from the original licensor to copy,
174distribute or modify the Program subject to these terms and conditions. You
175may not impose any further restrictions on the recipients' exercise of the rights
176granted herein. You are not responsible for enforcing compliance by third parties
177to this License.
178
1797. If, as a consequence of a court judgment or allegation of patent infringement
180or for any other reason (not limited to patent issues), conditions are imposed on
181you (whether by court order, agreement or otherwise) that contradict the
182conditions of this License, they do not excuse you from the conditions of this
183License. If you cannot distribute so as to satisfy simultaneously your obligations
184under this License and any other pertinent obligations, then as a consequence
185you may not distribute the Program at all. For example, if a patent license would
186not permit royalty-free redistribution of the Program by all those who receive
187copies directly or indirectly through you, then the only way you could satisfy
188both it and this License would be to refrain entirely from distribution of the
189Program.
190
191If any portion of this section is held invalid or unenforceable under any particular
192circumstance, the balance of the section is intended to apply and the section as
193a whole is intended to apply in other circumstances.
194
195It is not the purpose of this section to induce you to infringe any patents or other
196property right claims or to contest validity of any such claims; this section has
197the sole purpose of protecting the integrity of the free software distribution
198system, which is implemented by public license practices. Many people have
199made generous contributions to the wide range of software distributed through
200that system in reliance on consistent application of that system; it is up to the
201author/donor to decide if he or she is willing to distribute software through any
202other system and a licensee cannot impose that choice.
203
204This section is intended to make thoroughly clear what is believed to be a
205consequence of the rest of this License.
206
2078. If the distribution and/or use of the Program is restricted in certain countries
208either by patents or by copyrighted interfaces, the original copyright holder who
209places the Program under this License may add an explicit geographical
210distribution limitation excluding those countries, so that distribution is permitted
211only in or among countries not thus excluded. In such case, this License
212incorporates the limitation as if written in the body of this License.
213
2149. The Free Software Foundation may publish revised and/or new versions of the
215General Public License from time to time. Such new versions will be similar in
216spirit to the present version, but may differ in detail to address new problems or
217concerns.
218
219Each version is given a distinguishing version number. If the Program specifies a
220version number of this License which applies to it and "any later version", you
221have the option of following the terms and conditions either of that version or of
222any later version published by the Free Software Foundation. If the Program does
223not specify a version number of this License, you may choose any version ever
224published by the Free Software Foundation.
225
22610. If you wish to incorporate parts of the Program into other free programs
227whose distribution conditions are different, write to the author to ask for
228permission. For software which is copyrighted by the Free Software Foundation,
229write to the Free Software Foundation; we sometimes make exceptions for this.
230Our decision will be guided by the two goals of preserving the free status of all
231derivatives of our free software and of promoting the sharing and reuse of
232software generally.
233
234NO WARRANTY
235
23611. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
237NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
238APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
239COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
240"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
241IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
242MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
243ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
244PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
245YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
246CORRECTION.
247
24812. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED
249TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY
250WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS
251PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
252GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
253ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
254(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
255RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
256PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
257OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
258BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
259
260END OF TERMS AND CONDITIONS
