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

  337. This General Public License does not permit incorporating your program into\par
  338. proprietary programs. If your program is a subroutine library, you may\par
  339. consider it more useful to permit linking proprietary applications with the\par
  340. library. If this is what you want to do, use the GNU Lesser General\par
  341. Public License instead of this License.\par
  342. \par
