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