GNU Shogi is a computer program that plays the game of Shogi, also known as Japanese Chess.
GNU Shogi can be found on the main GNU ftp server: http://ftp.gnu.org/gnu/gnushogi/ (via HTTP) and ftp://ftp.gnu.org/gnu/gnushogi/ (via FTP). It can also be found on the GNU mirrors; please use a mirror if possible.
Documentation for GNU Shogi, including the rules of Shogi, is available online, as is documentation for most GNU software. You may also find more information about GNU Shogi by running info gnushogi or man gnushogi, or by looking at /usr/share/doc/gnushogi/, /usr/local/doc/gnushogi/, or similar directories on your system.
For more information on shogi, go to Pieter Stouten's shogi page, which has links to essentially all shogi-related material on the internet. Many thanks to Pieter for providing this service!
Wikipedia, also hosts useful information about the game, and versions of the rules in many languages.
Problems with GNU Shogi can be reported through the project's bug tracker.
GNU Shogi proper is only the AI engine, and you will likely want to use a GUI frontend to be more comfortable. The gnushogi program does include a text-based UI if you're into this sort of things, and the source distribution also includes the (very) old xshogi frontend for the X Window system. Suggested frontends include:
GNU Shogi has the following mailing lists:
Security reports that should not be made immediately public can be sent directly to the maintainer. If there is no response to an urgent issue, you can escalate to the general security mailing list for advice.
Development of GNU Shogi, and GNU in general, is a volunteer effort, and you can contribute. For information, please read How to help GNU. If you'd like to get involved, it's a good idea to join the discussion mailing list (see above).
