  78. as of the date such litigation is filed.

  85. (b) You must cause any modified files to carry prominent notices
  86. stating that You changed the files; and
  87. (c) You must retain, in the Source form of any Derivative Works
  88. that You distribute, all copyright, patent, trademark, and

  103. do not modify the License. You may add Your own attribution
  104. notices within Derivative Works that You distribute, alongside
  105. or as an addendum to the NOTICE text from the Work, provided
  106. that such additional attribution notices cannot be construed
  107. as modifying the License.
  108. You may add Your own copyright statement to Your modifications and

  113. the conditions stated in this License.
  114. 5. Submission of Contributions. Unless You explicitly state otherwise,
  115. any Contribution intentionally submitted for inclusion in the Work
  116. by You to the Licensor shall be under the terms and conditions of
  117. this License, without any additional terms or conditions.
  118. Notwithstanding the above, nothing herein shall supersede or modify
  119. the terms of any separate license agreement you may have executed
  120. with Licensor regarding such Contributions.
  121. 6. Trademarks. This License does not grant permission to use the trade
  122. names, trademarks, service marks, or product names of the Licensor,
  123. except as required for reasonable and customary use in describing the
  124. origin of the Work and reproducing the content of the NOTICE file.
  125. 7. Disclaimer of Warranty. Unless required by applicable law or
  126. agreed to in writing, Licensor provides the Work (and each
  127. Contributor provides its Contributions) on an "AS IS" BASIS,
  129. implied, including, without limitation, any warranties or conditions
  131. PARTICULAR PURPOSE. You are solely responsible for determining the
  132. appropriateness of using or redistributing the Work and assume any
  133. risks associated with Your exercise of permissions under this License.
  134. 8. Limitation of Liability. In no event and under no legal theory,
  135. whether in tort (including negligence), contract, or otherwise,
  136. unless required by applicable law (such as deliberate and grossly
  137. negligent acts) or agreed to in writing, shall any Contributor be
  138. liable to You for damages, including any direct, indirect, special,
  139. incidental, or consequential damages of any character arising as a
  140. result of this License or out of the use or inability to use the
  141. Work (including but not limited to damages for loss of goodwill,
  142. work stoppage, computer failure or malfunction, or any and all
  143. other commercial damages or losses), even if such Contributor
  144. has been advised of the possibility of such damages.
  145. 9. Accepting Warranty or Additional Liability. While redistributing
  146. the Work or Derivative Works thereof, You may choose to offer,
  147. and charge a fee for, acceptance of support, warranty, indemnity,
  148. or other liability obligations and/or rights consistent with this
  149. License. However, in accepting such obligations, You may act only
  150. on Your own behalf and on Your sole responsibility, not on behalf
  151. of any other Contributor, and only if You agree to indemnify,
  152. defend, and hold each Contributor harmless for any liability
  153. incurred by, or claims asserted against, such Contributor by reason
  154. of your accepting any such warranty or additional liability.
  155. ====
  156. The above license applies to all parts of Neovim except (1) parts that were
  157. contributed under the Vim license and (2) externally maintained libraries.
  158. The externally maintained libraries used by Neovim are:
  159. - Klib: a Generic Library in C. MIT/X11 license.
  160. - libuv. Copyright Joyent, Inc. and other Node contributors. Node.js license.
  161. - LuaJIT: a Just-In-Time Compiler for Lua. Copyright Mike Pall. MIT license.
  162. ====
  163. Any parts of Neovim that were contributed under the Vim license are licensed
  164. under the Vim license unless the copyright holder gave permission to license
  165. those contributions under the Apache 2.0 license.
  166. The Vim license follows:
  168. I) There are no restrictions on distributing unmodified copies of Vim except
  169. that they must include this license text. You can also distribute
  170. unmodified parts of Vim, likewise unrestricted except that they must
  171. include this license text. You are also allowed to include executables
  172. that you made from the unmodified Vim sources, plus your own usage
  173. examples and Vim scripts.
  174. II) It is allowed to distribute a modified (or extended) version of Vim,
  175. including executables and/or source code, when the following four
  176. conditions are met:
  177. 1) This license text must be included unmodified.
  178. 2) The modified Vim must be distributed in one of the following five ways:
  179. a) If you make changes to Vim yourself, you must clearly describe in
  180. the distribution how to contact you. When the maintainer asks you
  181. (in any way) for a copy of the modified Vim you distributed, you
  182. must make your changes, including source code, available to the
  183. maintainer without fee. The maintainer reserves the right to
  184. include your changes in the official version of Vim. What the
  185. maintainer will do with your changes and under what license they
  186. will be distributed is negotiable. If there has been no negotiation
  187. then this license, or a later version, also applies to your changes.
  188. The current maintainer is Bram Moolenaar <>. If this
  189. changes it will be announced in appropriate places (most likely
  190., and/or comp.editors). When it is completely
  191. impossible to contact the maintainer, the obligation to send him
  192. your changes ceases. Once the maintainer has confirmed that he has
  193. received your changes they will not have to be sent again.
  194. b) If you have received a modified Vim that was distributed as
  195. mentioned under a) you are allowed to further distribute it
  196. unmodified, as mentioned at I). If you make additional changes the
  197. text under a) applies to those changes.
  198. c) Provide all the changes, including source code, with every copy of
  199. the modified Vim you distribute. This may be done in the form of a
  200. context diff. You can choose what license to use for new code you
  201. add. The changes and their license must not restrict others from
  202. making their own changes to the official version of Vim.
  203. d) When you have a modified Vim which includes changes as mentioned
  204. under c), you can distribute it without the source code for the
  205. changes if the following three conditions are met:
  206. - The license that applies to the changes permits you to distribute
  207. the changes to the Vim maintainer without fee or restriction, and
  208. permits the Vim maintainer to include the changes in the official
  209. version of Vim without fee or restriction.
  210. - You keep the changes for at least three years after last
  211. distributing the corresponding modified Vim. When the maintainer
  212. or someone who you distributed the modified Vim to asks you (in
  213. any way) for the changes within this period, you must make them
  214. available to him.
  215. - You clearly describe in the distribution how to contact you. This
  216. contact information must remain valid for at least three years
  217. after last distributing the corresponding modified Vim, or as long
  218. as possible.
  219. e) When the GNU General Public License (GPL) applies to the changes,
  220. you can distribute the modified Vim under the GNU GPL version 2 or
  221. any later version.
  222. 3) A message must be added, at least in the output of the ":version"
  223. command and in the intro screen, such that the user of the modified Vim
  224. is able to see that it was modified. When distributing as mentioned
  225. under 2)e) adding the message is only required for as far as this does
  226. not conflict with the license used for the changes.
  227. 4) The contact information as required under 2)a) and 2)d) must not be
  228. removed or changed, except that the person himself can make
  229. corrections.
  230. III) If you distribute a modified version of Vim, you are encouraged to use
  231. the Vim license for your changes and make them available to the
  232. maintainer, including the source code. The preferred way to do this is
  233. by e-mail or by uploading the files to a server and e-mailing the URL.
  234. If the number of changes is small (e.g., a modified Makefile) e-mailing a
  235. context diff will do. The e-mail address to be used is
  236. <>
  237. IV) It is not allowed to remove this license from the distribution of the Vim
  238. sources, parts of it or from a modified version. You may use this
  239. license for previous Vim releases instead of the license that they came
  240. with, at your option.
