  7. GNU GENERAL PUBLIC LICENSE
  8. Version 2, June 1991
  9. Copyright (C) 1989, 1991 Free Software Foundation, Inc.
  10. 675 Mass Ave, Cambridge, MA 02139, USA
  11. Everyone is permitted to copy and distribute verbatim copies
  12. of this license document, but changing it is not allowed.
  13. Preamble
  14. The licenses for most software are designed to take away your
  15. freedom to share and change it. By contrast, the GNU General Public
  16. License is intended to guarantee your freedom to share and change free
  17. software--to make sure the software is free for all its users. This
  18. General Public License applies to most of the Free Software
  19. Foundation's software and to any other program whose authors commit to
  20. using it. (Some other Free Software Foundation software is covered by
  21. the GNU Library General Public License instead.) You can apply it to
  22. your programs, too.
  23. When we speak of free software, we are referring to freedom, not
  24. price. Our General Public Licenses are designed to make sure that you
  25. have the freedom to distribute copies of free software (and charge for
  26. this service if you wish), that you receive source code or can get it
  27. if you want it, that you can change the software or use pieces of it
  28. in new free programs; and that you know you can do these things.
  29. To protect your rights, we need to make restrictions that forbid
  30. anyone to deny you these rights or to ask you to surrender the rights.
  31. These restrictions translate to certain responsibilities for you if you
  32. distribute copies of the software, or if you modify it.
  33. For example, if you distribute copies of such a program, whether
  34. gratis or for a fee, you must give the recipients all the rights that
  35. you have. You must make sure that they, too, receive or can get the
  36. source code. And you must show them these terms so they know their
  37. rights.
  38. We protect your rights with two steps: (1) copyright the software, and
  39. (2) offer you this license which gives you legal permission to copy,
  40. distribute and/or modify the software.
  41. Also, for each author's protection and ours, we want to make certain
  42. that everyone understands that there is no warranty for this free
  43. software. If the software is modified by someone else and passed on, we
  44. want its recipients to know that what they have is not the original, so
  45. that any problems introduced by others will not reflect on the original
  46. authors' reputations.
  47. Finally, any free program is threatened constantly by software
  48. patents. We wish to avoid the danger that redistributors of a free
  49. program will individually obtain patent licenses, in effect making the
  50. program proprietary. To prevent this, we have made it clear that any
  51. patent must be licensed for everyone's free use or not licensed at all.
  52. The precise terms and conditions for copying, distribution and
  53. modification follow.
  54. GNU GENERAL PUBLIC LICENSE
  55. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  56. 0. This License applies to any program or other work which contains
  57. a notice placed by the copyright holder saying it may be distributed
  58. under the terms of this General Public License. The "Program", below,
  59. refers to any such program or work, and a "work based on the Program"
  60. means either the Program or any derivative work under copyright law:
  61. that is to say, a work containing the Program or a portion of it,
  62. either verbatim or with modifications and/or translated into another
  63. language. (Hereinafter, translation is included without limitation in
  64. the term "modification".) Each licensee is addressed as "you".
  65. Activities other than copying, distribution and modification are not
  66. covered by this License; they are outside its scope. The act of
  67. running the Program is not restricted, and the output from the Program
  68. is covered only if its contents constitute a work based on the
  69. Program (independent of having been made by running the Program).
  70. Whether that is true depends on what the Program does.
  71. 1. You may copy and distribute verbatim copies of the Program's
  72. source code as you receive it, in any medium, provided that you
  73. conspicuously and appropriately publish on each copy an appropriate
  74. copyright notice and disclaimer of warranty; keep intact all the
  75. notices that refer to this License and to the absence of any warranty;
  76. and give any other recipients of the Program a copy of this License
  77. along with the Program.
  78. You may charge a fee for the physical act of transferring a copy, and
  79. you may at your option offer warranty protection in exchange for a fee.
  80. 2. You may modify your copy or copies of the Program or any portion
  81. of it, thus forming a work based on the Program, and copy and
  82. distribute such modifications or work under the terms of Section 1
  83. above, provided that you also meet all of these conditions:
  84. a) You must cause the modified files to carry prominent notices
  85. stating that you changed the files and the date of any change.
  86. b) You must cause any work that you distribute or publish, that in
  87. whole or in part contains or is derived from the Program or any
  88. part thereof, to be licensed as a whole at no charge to all third
  89. parties under the terms of this License.
  90. c) If the modified program normally reads commands interactively
  91. when run, you must cause it, when started running for such
  92. interactive use in the most ordinary way, to print or display an
  93. announcement including an appropriate copyright notice and a
  94. notice that there is no warranty (or else, saying that you provide
  95. a warranty) and that users may redistribute the program under
  96. these conditions, and telling the user how to view a copy of this
  97. License. (Exception: if the Program itself is interactive but
  98. does not normally print such an announcement, your work based on
  99. the Program is not required to print an announcement.)
  100. These requirements apply to the modified work as a whole. If
  101. identifiable sections of that work are not derived from the Program,
  102. and can be reasonably considered independent and separate works in
  103. themselves, then this License, and its terms, do not apply to those
  104. sections when you distribute them as separate works. But when you
  105. distribute the same sections as part of a whole which is a work based
  106. on the Program, the distribution of the whole must be on the terms of
  107. this License, whose permissions for other licensees extend to the
  108. entire whole, and thus to each and every part regardless of who wrote it.
  109. Thus, it is not the intent of this section to claim rights or contest
  110. your rights to work written entirely by you; rather, the intent is to
  111. exercise the right to control the distribution of derivative or
  112. collective works based on the Program.
  113. In addition, mere aggregation of another work not based on the Program
  114. with the Program (or with a work based on the Program) on a volume of
  115. a storage or distribution medium does not bring the other work under
  116. the scope of this License.
  117. 3. You may copy and distribute the Program (or a work based on it,
  118. under Section 2) in object code or executable form under the terms of
  119. Sections 1 and 2 above provided that you also do one of the following:
  120. a) Accompany it with the complete corresponding machine-readable
  121. source code, which must be distributed under the terms of Sections
  122. 1 and 2 above on a medium customarily used for software interchange; or,
  123. b) Accompany it with a written offer, valid for at least three
  124. years, to give any third party, for a charge no more than your
  125. cost of physically performing source distribution, a complete
  126. machine-readable copy of the corresponding source code, to be
  127. distributed under the terms of Sections 1 and 2 above on a medium
  128. customarily used for software interchange; or,
  129. c) Accompany it with the information you received as to the offer
  130. to distribute corresponding source code. (This alternative is
  131. allowed only for noncommercial distribution and only if you
  132. received the program in object code or executable form with such
  133. an offer, in accord with Subsection b above.)
  134. The source code for a work means the preferred form of the work for
  135. making modifications to it. For an executable work, complete source
  136. code means all the source code for all modules it contains, plus any
  137. associated interface definition files, plus the scripts used to
  138. control compilation and installation of the executable. However, as a
  139. special exception, the source code distributed need not include
  140. anything that is normally distributed (in either source or binary
  141. form) with the major components (compiler, kernel, and so on) of the
  142. operating system on which the executable runs, unless that component
  143. itself accompanies the executable.
  144. If distribution of executable or object code is made by offering
  145. access to copy from a designated place, then offering equivalent
  146. access to copy the source code from the same place counts as
  147. distribution of the source code, even though third parties are not
  148. compelled to copy the source along with the object code.
  149. 4. You may not copy, modify, sublicense, or distribute the Program
  150. except as expressly provided under this License. Any attempt
  151. otherwise to copy, modify, sublicense or distribute the Program is
  152. void, and will automatically terminate your rights under this License.
  153. However, parties who have received copies, or rights, from you under
  154. this License will not have their licenses terminated so long as such
  155. parties remain in full compliance.
  156. 5. You are not required to accept this License, since you have not
  157. signed it. However, nothing else grants you permission to modify or
  158. distribute the Program or its derivative works. These actions are
  159. prohibited by law if you do not accept this License. Therefore, by
  160. modifying or distributing the Program (or any work based on the
  161. Program), you indicate your acceptance of this License to do so, and
  162. all its terms and conditions for copying, distributing or modifying
  163. the Program or works based on it.
  164. 6. Each time you redistribute the Program (or any work based on the
  165. Program), the recipient automatically receives a license from the
  166. original licensor to copy, distribute or modify the Program subject to
  167. these terms and conditions. You may not impose any further
  168. restrictions on the recipients' exercise of the rights granted herein.
  169. You are not responsible for enforcing compliance by third parties to
  170. this License.
  171. 7. If, as a consequence of a court judgment or allegation of patent
  172. infringement or for any other reason (not limited to patent issues),
  173. conditions are imposed on you (whether by court order, agreement or
  174. otherwise) that contradict the conditions of this License, they do not
  175. excuse you from the conditions of this License. If you cannot
  176. distribute so as to satisfy simultaneously your obligations under this
  177. License and any other pertinent obligations, then as a consequence you
  178. may not distribute the Program at all. For example, if a patent
  179. license would not permit royalty-free redistribution of the Program by
  180. all those who receive copies directly or indirectly through you, then
  181. the only way you could satisfy both it and this License would be to
  182. refrain entirely from distribution of the Program.
  183. If any portion of this section is held invalid or unenforceable under
  184. any particular circumstance, the balance of the section is intended to
  185. apply and the section as a whole is intended to apply in other
  186. circumstances.
  187. It is not the purpose of this section to induce you to infringe any
  188. patents or other property right claims or to contest validity of any
  189. such claims; this section has the sole purpose of protecting the
  190. integrity of the free software distribution system, which is
  191. implemented by public license practices. Many people have made
  192. generous contributions to the wide range of software distributed
  193. through that system in reliance on consistent application of that
  194. system; it is up to the author/donor to decide if he or she is willing
  195. to distribute software through any other system and a licensee cannot
  196. impose that choice.
  197. This section is intended to make thoroughly clear what is believed to
  198. be a consequence of the rest of this License.
  199. 8. If the distribution and/or use of the Program is restricted in
  200. certain countries either by patents or by copyrighted interfaces, the
  201. original copyright holder who places the Program under this License
  202. may add an explicit geographical distribution limitation excluding
  203. those countries, so that distribution is permitted only in or among
  204. countries not thus excluded. In such case, this License incorporates
  205. the limitation as if written in the body of this License.
  206. 9. The Free Software Foundation may publish revised and/or new versions
  207. of the General Public License from time to time. Such new versions will
  208. be similar in spirit to the present version, but may differ in detail to
  209. address new problems or concerns.
  210. Each version is given a distinguishing version number. If the Program
  211. specifies a version number of this License which applies to it and "any
  212. later version", you have the option of following the terms and conditions
  213. either of that version or of any later version published by the Free
  214. Software Foundation. If the Program does not specify a version number of
  215. this License, you may choose any version ever published by the Free Software
  216. Foundation.
  217. 10. If you wish to incorporate parts of the Program into other free
  218. programs whose distribution conditions are different, write to the author
  219. to ask for permission. For software which is copyrighted by the Free
  220. Software Foundation, write to the Free Software Foundation; we sometimes
  221. make exceptions for this. Our decision will be guided by the two goals
  222. of preserving the free status of all derivatives of our free software and
  223. of promoting the sharing and reuse of software generally.
  224. NO WARRANTY
  225. 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
  226. FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
  227. OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
  228. PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
  229. OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
  230. MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
  231. TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
  232. PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
  233. REPAIR OR CORRECTION.
  234. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  235. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  236. REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  237. INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  238. OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
  239. TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
  240. YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  241. PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  242. POSSIBILITY OF SUCH DAMAGES.
  243. END OF TERMS AND CONDITIONS
  244. Appendix: How to Apply These Terms to Your New Programs
  245. If you develop a new program, and you want it to be of the greatest
  246. possible use to the public, the best way to achieve this is to make it
  247. free software which everyone can redistribute and change under these terms.
  248. To do so, attach the following notices to the program. It is safest
  249. to attach them to the start of each source file to most effectively
  250. convey the exclusion of warranty; and each file should have at least
  251. the "copyright" line and a pointer to where the full notice is found.
  252. <one line to give the program's name and a brief idea of what it does.>
  253. Copyright (C) 19yy <name of author>
  254. This program is free software; you can redistribute it and/or modify
  255. it under the terms of the GNU General Public License as published by
  256. the Free Software Foundation; either version 2 of the License, or
  257. (at your option) any later version.
  258. This program is distributed in the hope that it will be useful,
  259. but WITHOUT ANY WARRANTY; without even the implied warranty of
  260. MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
  261. GNU General Public License for more details.
  262. You should have received a copy of the GNU General Public License
  263. along with this program; if not, write to the Free Software
  264. Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
  265. Also add information on how to contact you by electronic and paper mail.
  266. If the program is interactive, make it output a short notice like this
  267. when it starts in an interactive mode:
  268. Gnomovision version 69, Copyright (C) 19yy name of author
  269. Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  270. This is free software, and you are welcome to redistribute it
  271. under certain conditions; type `show c' for details.
  272. The hypothetical commands `show w' and `show c' should show the appropriate
  273. parts of the General Public License. Of course, the commands you use may
  274. be called something other than `show w' and `show c'; they could even be
  275. mouse-clicks or menu items--whatever suits your program.
  276. You should also get your employer (if you work as a programmer) or your
  277. school, if any, to sign a "copyright disclaimer" for the program, if
  278. necessary. Here is a sample; alter the names:
  279. Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  280. `Gnomovision' (which makes passes at compilers) written by James Hacker.
  281. <signature of Ty Coon>, 1 April 1989
  282. Ty Coon, President of Vice
  283. This General Public License does not permit incorporating your program into
  284. proprietary programs. If your program is a subroutine library, you may
  285. consider it more useful to permit linking proprietary applications with the
  286. library. If this is what you want to do, use the GNU Library General
  287. Public License instead of this License.
