   3 Goban is a a plugin for playing, viewing and recording games of Go (also known
   4 as Weiqi, Baduk, Igo and Goe).  It uses standard Smart Game Format (SGF) files
   5 for saving and loading games.
   6
   7 You can find a short introduction to Go at
   8 \url{http://senseis.xmp.net/?WhatIsGo} and more information about SGF files
   9 can be read at \url{http://senseis.xmp.net/?SmartGameFormat} or the SGF
  10 specification at
  11 \url{http://www.red-bean.com/sgf/}.
  12
  13 This plugin can load all modern SGF files (file format 3 or 4) with few problems.
  14 It attempts to preserve SGF properties which it doesn't understand, and most common
  15 SGF properties are handled fully.  It is possible to view (and edit if you like)
  16 Kogo's Joseki Dictionary (\url{http://waterfire.us/joseki.htm}) with this plugin,
  17 although the load and save times can be on the order of a minute or two on
  18 particularly slow devices.  Large SGF files may stop audio playback for the duration
  19 of the plugin's run in order to free up more memory and some very large SGF files will
  20 not even load on devices with little available memory.
  21
  22 \emph{Note: } The plugin does \emph{NOT} support SGF files with multiple games in
  23 one file.  These are rare, but if you have one don't even try it (the file will most
  24 likely be corrupted if you save over it).  You have been warned.
  25
  26 The file \fname {"/sgf/gbn\_def.sgf"} is used by the plugin to store any unsaved
  27 changes in the most recently loaded game.  This means that if you forget to save your
  28 changes, you should load \fname {"/sgf/gbn\_def.sgf"} immediately to offload the changes
  29 to another file.  If you load another file first then your changes will be lost
  30 permanently.  The \fname {"/sgf/gbn\_def.sgf"} file is also the file loaded if another
  31 is not selected.
  32
  33 The information panel which displays the current move number may also contain
  34 these markers: \\
  35 \begin{tabularx}{\textwidth}{lX}\toprule
  36 \textbf{Mark} & \textbf{Meaning} \\ \midrule
  37     \emph{+ } & There are nodes after the current node in the SGF tree. \\

 150 \subsubsection{Menus}
 151 \begin {description}
 152 \item [Main Menu. ]
 153     The main menu for game setup and access to other menus.
 154
 155     \emph {New. } Create a new game with your choice of board size and handicaps. \\
 156     \emph {Save. } Save the current state of the game.  It will be saved to
 157     \fname {"/sgf/gbn\_def.sgf"} unless otherwise set. \\
 158     \emph {Save As. } Save to a specified file. \\
 159     \emph {Game Info. } View and modify the metadata of the current game. \\
 160     \emph {Playback Control. } Control the playback of the current playlist and
 161     modify the volume of your player. \\
 162     \emph {Zoom Level. } Zoom in or out on the board.  If you set the zoom level, it

 164     \emph {Options. } Open the Options Menu. \\
 165     \emph {Context Menu. } Open the Context Menu which allows you to set play modes
 166     and other tools. \\
 167     \emph {Quit. } Leave the plugin.  Any unsaved changes are saved to
 168     \fname {"/sgf/gbn\_def.sgf"}. \\
 169
 170 \item [Game Info. ]
 171     The menu for modifying game info (metadata) of the current game.  This
 172     information will be saved to the SGF file and can be viewed in almost all
 173     SGF readers.
 174
 175     \emph {Basic Info. } Shows a quick view of the basic game metadata, if any
 176     has been set (otherwise does nothing).  This option does not allow editing. \\
 177     \emph {Time Limit. } The time limit of the current game. \\
 178     \emph {Overtime. } The overtime settings of the current game. \\
 179     \emph {Result. } The result of the current game.  This text must follow the
 180     format specified at \url{http://www.red-bean.com/sgf/properties.html#RE} to
 181     be read by other SGF readers.  Some examples are \emph {B+R} (Black wins by
 182     resignation), \emph {B+5.5} (Black wins by 5.5 points), \emph {W+T} (White wins
 183     on Time). \\
 184     \emph {Handicap. } The handicap of the current game. \\
 185     \emph {Komi. } The komi of the current game (compensation to the white
 186     player for black having the first move). \\
 187     \emph {Ruleset. } The name of the ruleset in use for this game.  The \emph{NZ}
 188     and \emph{GOE} rulesets include suicide as a legal move (for multi-stone
 189     suicide only); the rest do not. \\
 190     \emph {Black Player. } The name of the black player. \\
 191     \emph {Black Rank. } Black's rank, in dan or kyu. \\
 192     \emph {Black Team. } The name of black's team, if any. \\
 193     \emph {White Player. } The name of the white player. \\
 194     \emph {White Rank. }  White's rank, in dan or kyu. \\
 195     \emph {White Team. } The name of white's team, if any. \\
 196     \emph {Date. } The date that this game took place.  This text must follow the
 197     format specified at \url{http://www.red-bean.com/sgf/properties.html#DT} to
 198     be read by other SGF readers. \\
 199     \emph {Event. } The name of the event which this game was a part of, if any.
 200     \\
 201     \emph {Place. } The place that this game took place. \\
 202     \emph {Round. } If part of a tournament, the round number for this game. \\
 203     \emph {Done. } Return to the previous menu. \\
 204
 205 \item [Options. ]
 206     Customize the behavior of the plugin in certain ways.
 207
 208     \emph {Show Child Variations? } Enable this to mark child variations on the board
 209     if there are more than one.  Note: variations which don't start with a move are
 210     not visible in this way. \\
 211     \emph {Disable Idle Poweroff? } Enable this if you do not want the \dap{} to turn
 212     off after a certain period of inactivity (depends on your global Rockbox
 213     settings). \\
 214     \emph {Idle Autosave Time. } Set the amount of idle time to wait before
 215     automatically saving any unsaved changes.  These autosaves go to the file
 216     \fname {"/sgf/gbn\_def.sgf"} regardless of if you have loaded a game or used
 217     \emph {Save As} to save the game before or not.  Set to \emph {Off} to disable
 218     this functionality completely. \\
 219     \emph {Automatically Show Comments? } If this is enabled and you navigate to a
 220     node containing game comments, they will automatically be displayed. \\
 221
 222 \item [Context Menu. ]
 223     The menu for choosing different play modes and tools, adding or editing
 224     comments, adding pass moves, or switching between sibling variations.
 225
 226     \emph {Play Mode. } Play moves normally on the board.  If there are
 227     child moves from the current node, this mode will let you follow variations
 228     by simply playing the first move in the sequence.  Unless it is following a
 229     variation, this mode will not allow you to play illegal moves.  This is the
 230     default mode before another is set after loading a game or creating a new
 231     one. \\
 232     \emph {Add Black Mode. } Add black stones to the board as desired. These
 233     stones are not moves and do not perform captures or count as ko threats. \\
 234     \emph {Add White Mode. } Add white stones to the board as desired. These
 235     stones are not moves and do not perform captures or count as ko threats. \\
 236     \emph {Erase Stone Mode. } Remove stones from the board as desired.  These
 237     removed stones are not counted as captured, they are simply removed. \\
 238     \emph {Pass. } Play a single pass move.  This does not change the mode of
 239     play. \\
 240     \emph {Next Variation. } If the game is at the first move in a variation,
 241     this will navigate to the next variation after the current one.  This is
 242     the only way to reach variations which start with adding or removing
 243     stones, as you cannot follow them by "playing" the same move. \\
 244     \emph {Force Play Mode. } The same as Play Mode except that this mode will
 245     allow you to play illegal moves such as retaking a ko immediately without a
 246     ko threat, suicide on rulesets which don't allow it (including single stone
 247     suicide), and playing a move where there is already a stone. \\
 248     \emph {Mark Mode. } Add generic marks to the board, or remove them. \\
 249     \emph {Circle Mode. } Add circle marks to the board, or remove them. \\
 250     \emph {Square Mode. } Add square marks to the board, or remove them. \\
 251     \emph {Triangle Mode. } Add triangle marks to the board, or remove them. \\
 252     \emph {Label Mode. } Add one character labels to the board.  Each label
 253     starts at the letter 'a' and each subsequent application of a label will
 254     increment the letter.  To remove a label, click on it until it cycles
 255     through the allowed letters and disappears. \\
 256     \emph {Add/Edit Comment. } Add or edit a comment at the current node. \\
 257     \emph {Done. } Go back to the previous screen. \\
