If graphics are enabled (default), then the user will be prompted to choose any of the two players not supplied as arguments.
+ --reveal
+ If graphics are enabled, the two states for pieces will always be shown, regardless of whether both states have been revealed.
+ Note that this switch only affects the GUI and does not provide any information to agent players.
- --file[=filename]
+ If graphics are disabled, has no effect.
+
+ --file[=filename][:events]
Replay a game saved in file, or read from stdin if no filename given
+ If a number of events is supplied, the game will advance that many events before stopping.
+
+ If no players are given, the GUI will NOT ask for player selections.
+ The game will exit after the replay finishes. Events in the replay will be subject to the normal delay (see --delay).
+
+ If black and white players are supplied, the game will continue using those players.
+ In this case, there will be no delays between events in the replay (the game starts at the end of the replay)
+
+ (We hope that) this feature will be useful for comparing how different versions of an agent respond to the same situation.
