Play GNU Go in a buffer
Playing
-------
This file provides the command `gnugo' which allows you to play the game of
go against the external program "gnugo" (https://www.gnu.org/software/gnugo)
in a dedicated Emacs buffer, or to resume a game in progress. NOTE: In
this file, to avoid confusion w/ elisp vars and funcs, we use the term "GNU
Go" to refer to the process object created by running the external program.
At the start of a new game, you can pass additional command-line arguments
to GNU Go to specify level, board size, color, komi, handicap, etc. By
default GNU Go plays at level 10, board size 19, color white, and zero for
both komi and handicap.
To play a stone, move the cursor to the desired vertice and type `SPC' or
`RET'; to pass, `P' (note: uppercase); to quit, `q'; to undo one of your
moves (as well as a possibly intervening move by GNU Go), `u'. To undo
back through an arbitrary stone that you played, place the cursor on a
stone and type `U' (note: uppercase).
There are a great many other commands. Other keybindings are described in
the `gnugo-board-mode' documentation, which you may view with the command
`describe-mode' (normally `C-h m') in that buffer. The buffer name shows
the last move and who is currently to play. Capture counts and other info
are shown on the mode line immediately following the major mode name.
While GNU Go is pondering its next move, certain commands that rely on its
assistance will result in a "still waiting" error. Do not be alarmed; that
is normal. When it is your turn again you may retry the command. In the
meantime, you can use Emacs for other tasks, or start an entirely new game
with `C-u M-x gnugo'. (NOTE: A new game will slow down all games. :-)
If GNU Go should crash during a game the mode line will show "no process".
Please report the event to the GNU Go maintainers so that they can improve
the program.

Customization is presently limited to
vars: `gnugo-program'
`gnugo-animation-string'
`gnugo-mode-line'
`gnugo-X-face' `gnugo-O-face' `gnugo-grid-face'
`gnugo-undo-reaction'
`gnugo-xpms' (see also gnugo-imgen.el)
normal hooks: `gnugo-board-mode-hook'
`gnugo-frolic-mode-hook'
`gnugo-start-game-hook'
`gnugo-post-move-hook'
and the keymaps: `gnugo-board-mode-map'
