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

  295. This General Public License does not permit incorporating your program into
  296. proprietary programs. If your program is a subroutine library, you may
  297. consider it more useful to permit linking proprietary applications with the
  298. library. If this is what you want to do, use the GNU Library General
  299. Public License instead of this License.
