6 This command is used by a person examining a game in order to move backward
7 in the sequence of the game's moves. If # is not specified, 1 will be used.
9 In the case of a stored game, you may move forward again using the "forward"
10 command, but in the case of a new game you will need to move the pieces again.
12 SPECIAL NOTE: The "revert" command is a way to move backward to the branch
13 from the main variation being examined.
