   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: \\

 158 \subsubsection{Menus}
 159 \begin {description}
 160 \item [Main Menu. ]
 161     The main menu for game setup and access to other menus.
 162
 163     \emph {New. } Create a new game with your choice of board size and handicaps. \\
 164     \emph {Save. } Save the current state of the game.  It will be saved to
 165     \fname {"/sgf/gbn\_def.sgf"} unless otherwise set. \\
 166     \emph {Save As. } Save to a specified file. \\
 167     \emph {Game Info. } View and modify the metadata of the current game. \\
 168     \emph {Playback Control. } Control the playback of the current playlist and
 169     modify the volume of your player. \\
 170     \emph {Zoom Level. } Zoom in or out on the board.  If you set the zoom level, it
 171     will be saved and used again the next time you open this plugin. \\
 172     \emph {Options. } Open the Options Menu. \\
 173     \emph {Context Menu. } Open the Context Menu which allows you to set play modes
 174     and other tools. \\
 175     \emph {Quit. } Leave the plugin.  Any unsaved changes are saved to
 176     \fname {"/sgf/gbn\_def.sgf"}. \\
 177
 178 \item [Game Info. ]
 179     The menu for modifying game info (metadata) of the current game.  This
 180     information will be saved to the SGF file and can be viewed in almost all
 181     SGF readers.
 182
 183     \emph {Basic Info. } Shows a quick view of the basic game metadata, if any
 184     has been set (otherwise does nothing).  This option does not allow editing. \\
 185     \emph {Time Limit. } The time limit of the current game. \\
 186     \emph {Overtime. } The overtime settings of the current game. \\
 187     \emph {Result. } The result of the current game.  This text must follow the
 188     format specified at \url{http://www.red-bean.com/sgf/properties.html#RE} to
 189     be read by other SGF readers.  Some examples are \emph {B+R} (Black wins by
 190     resignation), \emph {B+5.5} (Black wins by 5.5 points), \emph {W+T} (White wins
 191     on Time). \\
 192     \emph {Handicap. } The handicap of the current game. \\
 193     \emph {Komi. } The komi of the current game (compensation to the white
 194     player for black having the first move). \\
 195     \emph {Ruleset. } The name of the ruleset in use for this game.  The \emph{NZ}
 196     and \emph{GOE} rulesets include suicide as a legal move (for multi-stone
 197     suicide only); the rest do not. \\
 198     \emph {Black Player. } The name of the black player. \\
 199     \emph {Black Rank. } Black's rank, in dan or kyu. \\
 200     \emph {Black Team. } The name of black's team, if any. \\
 201     \emph {White Player. } The name of the white player. \\
 202     \emph {White Rank. }  White's rank, in dan or kyu. \\
 203     \emph {White Team. } The name of white's team, if any. \\
 204     \emph {Date. } The date that this game took place.  This text must follow the
 205     format specified at \url{http://www.red-bean.com/sgf/properties.html#DT} to
 206     be read by other SGF readers. \\
 207     \emph {Event. } The name of the event which this game was a part of, if any.
 208     \\
 209     \emph {Place. } The place that this game took place. \\
 210     \emph {Round. } If part of a tournament, the round number for this game. \\
 211     \emph {Done. } Return to the previous menu. \\
 212
 213 \item [Options. ]
 214     Customize the behavior of the plugin in certain ways.
 215
 216     \emph {Show Child Variations? } Enable this to mark child variations on the board
 217     if there are more than one.  Note: variations which don't start with a move are
 218     not visible in this way. \\
 219     \emph {Disable Idle Poweroff? } Enable this if you do not want the \dap{} to turn
 220     off after a certain period of inactivity (depends on your global Rockbox
 221     settings). \\
 222     \emph {Idle Autosave Time. } Set the amount of idle time to wait before
 223     automatically saving any unsaved changes.  These autosaves go to the file
 224     \fname {"/sgf/gbn\_def.sgf"} regardless of if you have loaded a game or used
 225     \emph {Save As} to save the game before or not.  Set to \emph {Off} to disable
 226     this functionality completely. \\
 227     \emph {Automatically Show Comments? } If this is enabled and you navigate to a
 228     node containing game comments, they will automatically be displayed. \\
 229
 230 \item [Context Menu. ]
 231     The menu for choosing different play modes and tools, adding or editing
 232     comments, adding pass moves, or switching between sibling variations.
 233
 234     \emph {Play Mode. } Play moves normally on the board.  If there are
 235     child moves from the current node, this mode will let you follow variations
 236     by simply playing the first move in the sequence.  Unless it is following a
 237     variation, this mode will not allow you to play illegal moves.  This is the
 238     default mode before another is set after loading a game or creating a new
 239     one. \\
 240     \emph {Add Black Mode. } Add black stones to the board as desired. These
 241     stones are not moves and do not perform captures or count as ko threats. \\
 242     \emph {Add White Mode. } Add white stones to the board as desired. These
 243     stones are not moves and do not perform captures or count as ko threats. \\
 244     \emph {Erase Stone Mode. } Remove stones from the board as desired.  These
 245     removed stones are not counted as captured, they are simply removed. \\
 246     \emph {Pass. } Play a single pass move.  This does not change the mode of
 247     play. \\
 248     \emph {Next Variation. } If the game is at the first move in a variation,
 249     this will navigate to the next variation after the current one.  This is
 250     the only way to reach variations which start with adding or removing
 251     stones, as you cannot follow them by "playing" the same move. \\
 252     \emph {Force Play Mode. } The same as Play Mode except that this mode will
 253     allow you to play illegal moves such as retaking a ko immediately without a
 254     ko threat, suicide on rulesets which don't allow it (including single stone
 255     suicide), and playing a move where there is already a stone. \\
 256     \emph {Mark Mode. } Add generic marks to the board, or remove them. \\
 257     \emph {Circle Mode. } Add circle marks to the board, or remove them. \\
 258     \emph {Square Mode. } Add square marks to the board, or remove them. \\
 259     \emph {Triangle Mode. } Add triangle marks to the board, or remove them. \\
 260     \emph {Label Mode. } Add one character labels to the board.  Each label
 261     starts at the letter 'a' and each subsequent application of a label will
 262     increment the letter.  To remove a label, click on it until it cycles
 263     through the allowed letters and disappears. \\
 264     \emph {Add/Edit Comment. } Add or edit a comment at the current node. \\
 265     \emph {Done. } Go back to the previous screen. \\
