Credits and notices

The wopr code is MIT licensed. That licence does not cover the film’s text, or the third-party text and art that wopr uses. This page is the repository’s NOTICE.md, which also ships with every download. The screenshots on this site show some of that material.

Code

The source code of wopr is licensed under the MIT License. See LICENSE. The MIT grant covers the code only. It does not cover the material listed under “Film text”, “Third-party text” and “Third-party art” below.

Film text

wopr is a fan-made homage to the 1983 film WarGames. It quotes short passages of the text that the film shows on the WOPR computer’s terminal. They are the game list, log-on and greeting lines, NORAD notices and similar screen text. Those quotations remain the property of their copyright holders. They are not licensed under the MIT License. They are listed with a provenance tag in internal/wopr/lines.go, internal/assets/, internal/movie/scenes/ and the games’ packages under internal/games/ (Global Thermonuclear War, tic-tac-toe and the ending). Movie mode (wopr --movie) replays the film’s terminal scenes with that text, including the lines typed at the terminal. It contains no dialogue that is only spoken, no audio and no stills.

This project is not affiliated with, endorsed by, or sponsored by Metro-Goldwyn-Mayer, United Artists, or anyone involved in making the film. WarGames is a trademark of its owner. It is used here only to describe what inspired this project. “WOPR” is used as the name of the film’s fictional computer.

Third-party text

Two items of the film’s screen text come from the transcription made by the abs0/wargames project (https://github.com/abs0/wargames, wargames.sh, commit 010ed92):

  • the “backdoor” connection header block shown after log-on.
  • the list of scenario names shown in the closing montage. Thirteen of the names are spelt as two other readings of the montage have them, where both differ from abs0’s (docs/PLAN.md §2.3).

abs0’s BSD 2-clause licence, reproduced below, covers the transcription. The text itself is the film’s, so like the other film text it is not covered by the MIT grant.

Third-party art

The big board’s world map in Global Thermonuclear War is Matthew Thomas’s ASCII world map, from https://asciiart.website/art/3719, reproduced exactly as he drew it. The board shows its northern rows. The map is used under the terms its author gave with it:

Map (C) 1998 Matthew Thomas. Freely usable if this line is included.

Map data

The side-choice outlines of the United States and the Soviet Union in Global Thermonuclear War are original ASCII art. They were generated for this project from Natural Earth country polygons (1:50m scale). Natural Earth is in the public domain. This credit is a courtesy.

Earlier drafts

An early draft of this project’s plan (commit ada63a0 in the git history) contained fragments of an ASCII world map. The map is from Franklin Wei’s wargames project (https://github.com/built1n/wargames, file MAP). docs/reviews/PLAN-v1-review.md quotes three of them. Those fragments are by Franklin Wei. They are available under the Creative Commons Attribution-ShareAlike 4.0 licence. The wopr program does not contain them.

Third-party software

The wopr binary is built with Go and links third-party Go modules. Their licences are reproduced in THIRD_PARTY_NOTICES.txt. That file ships in every release archive, and wopr --licenses prints it.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions

      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,

      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,

      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS
