  13. GNU GENERAL PUBLIC LICENSE
  14. Version 2, June 1991
  15. Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
  16. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
  17. Everyone is permitted to copy and distribute verbatim copies
  18. of this license document, but changing it is not allowed.
  19. Preamble
  20. The licenses for most software are designed to take away your
  21. freedom to share and change it. By contrast, the GNU General Public
  22. License is intended to guarantee your freedom to share and change free
  23. software--to make sure the software is free for all its users. This
  24. General Public License applies to most of the Free Software
  25. Foundation's software and to any other program whose authors commit to
  26. using it. (Some other Free Software Foundation software is covered by
  27. the GNU Lesser General Public License instead.) You can apply it to
  28. your programs, too.
  29. When we speak of free software, we are referring to freedom, not
  30. price. Our General Public Licenses are designed to make sure that you
  31. have the freedom to distribute copies of free software (and charge for
  32. this service if you wish), that you receive source code or can get it
  33. if you want it, that you can change the software or use pieces of it
  34. in new free programs; and that you know you can do these things.
  35. To protect your rights, we need to make restrictions that forbid
  36. anyone to deny you these rights or to ask you to surrender the rights.
  37. These restrictions translate to certain responsibilities for you if you
  38. distribute copies of the software, or if you modify it.
  39. For example, if you distribute copies of such a program, whether
  40. gratis or for a fee, you must give the recipients all the rights that
  41. you have. You must make sure that they, too, receive or can get the
  42. source code. And you must show them these terms so they know their
  43. rights.
  44. We protect your rights with two steps: (1) copyright the software, and
  45. (2) offer you this license which gives you legal permission to copy,
  46. distribute and/or modify the software.
  47. Also, for each author's protection and ours, we want to make certain
  48. that everyone understands that there is no warranty for this free
  49. software. If the software is modified by someone else and passed on, we
  50. want its recipients to know that what they have is not the original, so
  51. that any problems introduced by others will not reflect on the original
  52. authors' reputations.
  53. Finally, any free program is threatened constantly by software
  54. patents. We wish to avoid the danger that redistributors of a free
  55. program will individually obtain patent licenses, in effect making the
  56. program proprietary. To prevent this, we have made it clear that any
  57. patent must be licensed for everyone's free use or not licensed at all.
  58. The precise terms and conditions for copying, distribution and
  59. modification follow.
  60. GNU GENERAL PUBLIC LICENSE
  61. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  62. 0. This License applies to any program or other work which contains
  63. a notice placed by the copyright holder saying it may be distributed
  64. under the terms of this General Public License. The "Program", below,
  65. refers to any such program or work, and a "work based on the Program"
  66. means either the Program or any derivative work under copyright law:
  67. that is to say, a work containing the Program or a portion of it,
  68. either verbatim or with modifications and/or translated into another
  69. language. (Hereinafter, translation is included without limitation in
  70. the term "modification".) Each licensee is addressed as "you".
  71. Activities other than copying, distribution and modification are not
  72. covered by this License; they are outside its scope. The act of
  73. running the Program is not restricted, and the output from the Program
  74. is covered only if its contents constitute a work based on the
  75. Program (independent of having been made by running the Program).
  76. Whether that is true depends on what the Program does.
  77. 1. You may copy and distribute verbatim copies of the Program's
  78. source code as you receive it, in any medium, provided that you
  79. conspicuously and appropriately publish on each copy an appropriate
  80. copyright notice and disclaimer of warranty; keep intact all the
  81. notices that refer to this License and to the absence of any warranty;
  82. and give any other recipients of the Program a copy of this License
  83. along with the Program.
  84. You may charge a fee for the physical act of transferring a copy, and
  85. you may at your option offer warranty protection in exchange for a fee.
  86. 2. You may modify your copy or copies of the Program or any portion
  87. of it, thus forming a work based on the Program, and copy and
  88. distribute such modifications or work under the terms of Section 1
  89. above, provided that you also meet all of these conditions:
  90. a) You must cause the modified files to carry prominent notices
  91. stating that you changed the files and the date of any change.
  92. b) You must cause any work that you distribute or publish, that in
  93. whole or in part contains or is derived from the Program or any
  94. part thereof, to be licensed as a whole at no charge to all third
  95. parties under the terms of this License.
  96. c) If the modified program normally reads commands interactively
  97. when run, you must cause it, when started running for such
  98. interactive use in the most ordinary way, to print or display an
  99. announcement including an appropriate copyright notice and a
  100. notice that there is no warranty (or else, saying that you provide
  101. a warranty) and that users may redistribute the program under
  102. these conditions, and telling the user how to view a copy of this
  103. License. (Exception: if the Program itself is interactive but
  104. does not normally print such an announcement, your work based on
  105. the Program is not required to print an announcement.)
  106. These requirements apply to the modified work as a whole. If
  107. identifiable sections of that work are not derived from the Program,
  108. and can be reasonably considered independent and separate works in
  109. themselves, then this License, and its terms, do not apply to those
  110. sections when you distribute them as separate works. But when you
  111. distribute the same sections as part of a whole which is a work based
  112. on the Program, the distribution of the whole must be on the terms of
  113. this License, whose permissions for other licensees extend to the
  114. entire whole, and thus to each and every part regardless of who wrote it.
  115. Thus, it is not the intent of this section to claim rights or contest
  116. your rights to work written entirely by you; rather, the intent is to
  117. exercise the right to control the distribution of derivative or
  118. collective works based on the Program.
  119. In addition, mere aggregation of another work not based on the Program
  120. with the Program (or with a work based on the Program) on a volume of
  121. a storage or distribution medium does not bring the other work under
  122. the scope of this License.
  123. 3. You may copy and distribute the Program (or a work based on it,
  124. under Section 2) in object code or executable form under the terms of
  125. Sections 1 and 2 above provided that you also do one of the following:
  126. a) Accompany it with the complete corresponding machine-readable
  127. source code, which must be distributed under the terms of Sections
  128. 1 and 2 above on a medium customarily used for software interchange; or,
  129. b) Accompany it with a written offer, valid for at least three
  130. years, to give any third party, for a charge no more than your
  131. cost of physically performing source distribution, a complete
  132. machine-readable copy of the corresponding source code, to be
  133. distributed under the terms of Sections 1 and 2 above on a medium
  134. customarily used for software interchange; or,
  135. c) Accompany it with the information you received as to the offer
  136. to distribute corresponding source code. (This alternative is
  137. allowed only for noncommercial distribution and only if you
  138. received the program in object code or executable form with such
  139. an offer, in accord with Subsection b above.)
  140. The source code for a work means the preferred form of the work for
  141. making modifications to it. For an executable work, complete source
  142. code means all the source code for all modules it contains, plus any
  143. associated interface definition files, plus the scripts used to
  144. control compilation and installation of the executable. However, as a
  145. special exception, the source code distributed need not include
  146. anything that is normally distributed (in either source or binary
  147. form) with the major components (compiler, kernel, and so on) of the
  148. operating system on which the executable runs, unless that component
  149. itself accompanies the executable.
  150. If distribution of executable or object code is made by offering
  151. access to copy from a designated place, then offering equivalent
  152. access to copy the source code from the same place counts as
  153. distribution of the source code, even though third parties are not
  154. compelled to copy the source along with the object code.
  155. 4. You may not copy, modify, sublicense, or distribute the Program
  156. except as expressly provided under this License. Any attempt
  157. otherwise to copy, modify, sublicense or distribute the Program is
  158. void, and will automatically terminate your rights under this License.
  159. However, parties who have received copies, or rights, from you under
  160. this License will not have their licenses terminated so long as such
  161. parties remain in full compliance.
  162. 5. You are not required to accept this License, since you have not
  163. signed it. However, nothing else grants you permission to modify or
  164. distribute the Program or its derivative works. These actions are
  165. prohibited by law if you do not accept this License. Therefore, by
  166. modifying or distributing the Program (or any work based on the
  167. Program), you indicate your acceptance of this License to do so, and
  168. all its terms and conditions for copying, distributing or modifying
  169. the Program or works based on it.
  170. 6. Each time you redistribute the Program (or any work based on the
  171. Program), the recipient automatically receives a license from the
  172. original licensor to copy, distribute or modify the Program subject to
  173. these terms and conditions. You may not impose any further
  174. restrictions on the recipients' exercise of the rights granted herein.
  175. You are not responsible for enforcing compliance by third parties to
  176. this License.
  177. 7. If, as a consequence of a court judgment or allegation of patent
  178. infringement or for any other reason (not limited to patent issues),
  179. conditions are imposed on you (whether by court order, agreement or
  180. otherwise) that contradict the conditions of this License, they do not
  181. excuse you from the conditions of this License. If you cannot
  182. distribute so as to satisfy simultaneously your obligations under this
  183. License and any other pertinent obligations, then as a consequence you
  184. may not distribute the Program at all. For example, if a patent
  185. license would not permit royalty-free redistribution of the Program by
  186. all those who receive copies directly or indirectly through you, then
  187. the only way you could satisfy both it and this License would be to
  188. refrain entirely from distribution of the Program.
  189. If any portion of this section is held invalid or unenforceable under
  190. any particular circumstance, the balance of the section is intended to
  191. apply and the section as a whole is intended to apply in other
  192. circumstances.
  193. It is not the purpose of this section to induce you to infringe any
  194. patents or other property right claims or to contest validity of any
  195. such claims; this section has the sole purpose of protecting the
  196. integrity of the free software distribution system, which is
  197. implemented by public license practices. Many people have made
  198. generous contributions to the wide range of software distributed
  199. through that system in reliance on consistent application of that
  200. system; it is up to the author/donor to decide if he or she is willing
  201. to distribute software through any other system and a licensee cannot
  202. impose that choice.
  203. This section is intended to make thoroughly clear what is believed to
  204. be a consequence of the rest of this License.
  205. 8. If the distribution and/or use of the Program is restricted in
  206. certain countries either by patents or by copyrighted interfaces, the
  207. original copyright holder who places the Program under this License
  208. may add an explicit geographical distribution limitation excluding
  209. those countries, so that distribution is permitted only in or among
  210. countries not thus excluded. In such case, this License incorporates
  211. the limitation as if written in the body of this License.
  212. 9. The Free Software Foundation may publish revised and/or new versions
  213. of the General Public License from time to time. Such new versions will
  214. be similar in spirit to the present version, but may differ in detail to
  215. address new problems or concerns.
  216. Each version is given a distinguishing version number. If the Program
  217. specifies a version number of this License which applies to it and "any
  218. later version", you have the option of following the terms and conditions
  219. either of that version or of any later version published by the Free
  220. Software Foundation. If the Program does not specify a version number of
  221. this License, you may choose any version ever published by the Free Software
  222. Foundation.
  223. 10. If you wish to incorporate parts of the Program into other free
  224. programs whose distribution conditions are different, write to the author
  225. to ask for permission. For software which is copyrighted by the Free
  226. Software Foundation, write to the Free Software Foundation; we sometimes
  227. make exceptions for this. Our decision will be guided by the two goals
  228. of preserving the free status of all derivatives of our free software and
  229. of promoting the sharing and reuse of software generally.
  230. NO WARRANTY
  231. 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
  232. FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
  233. OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
  234. PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
  235. OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
  236. MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
  237. TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
  238. PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
  239. REPAIR OR CORRECTION.
  240. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  241. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  242. REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  243. INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  244. OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
  245. TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
  246. YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  247. PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  248. POSSIBILITY OF SUCH DAMAGES.
  249. END OF TERMS AND CONDITIONS
  250. How to Apply These Terms to Your New Programs
  251. If you develop a new program, and you want it to be of the greatest
  252. possible use to the public, the best way to achieve this is to make it
  253. free software which everyone can redistribute and change under these terms.
  254. To do so, attach the following notices to the program. It is safest
  255. to attach them to the start of each source file to most effectively
  256. convey the exclusion of warranty; and each file should have at least
  257. the "copyright" line and a pointer to where the full notice is found.
  258. <one line to give the program's name and a brief idea of what it does.>
  259. Copyright (C) <year> <name of author>
  260. This program is free software; you can redistribute it and/or modify
  261. it under the terms of the GNU General Public License as published by
  262. the Free Software Foundation; either version 2 of the License, or
  263. (at your option) any later version.
  264. This program is distributed in the hope that it will be useful,
  265. but WITHOUT ANY WARRANTY; without even the implied warranty of
  266. MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
  267. GNU General Public License for more details.
  268. You should have received a copy of the GNU General Public License along
  269. with this program; if not, write to the Free Software Foundation, Inc.,
  270. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
  271. Also add information on how to contact you by electronic and paper mail.
  272. If the program is interactive, make it output a short notice like this
  273. when it starts in an interactive mode:
  274. Gnomovision version 69, Copyright (C) year name of author
  275. Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  276. This is free software, and you are welcome to redistribute it
  277. under certain conditions; type `show c' for details.
  278. The hypothetical commands `show w' and `show c' should show the appropriate
  279. parts of the General Public License. Of course, the commands you use may
  280. be called something other than `show w' and `show c'; they could even be
  281. mouse-clicks or menu items--whatever suits your program.
  282. You should also get your employer (if you work as a programmer) or your
  283. school, if any, to sign a "copyright disclaimer" for the program, if
  284. necessary. Here is a sample; alter the names:
  285. Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  286. `Gnomovision' (which makes passes at compilers) written by James Hacker.
  287. <signature of Ty Coon>, 1 April 1989
  288. Ty Coon, President of Vice
  289. This General Public License does not permit incorporating your program into
  290. proprietary programs. If your program is a subroutine library, you may
  291. consider it more useful to permit linking proprietary applications with the
  292. library. If this is what you want to do, use the GNU Lesser General
  293. Public License instead of this License.
