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

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