* BookUp() is used to create/add to the opening book file. typing "<file> *
* create" will erase the old book file and start from scratch, *
* *
* The format of the input data is a left bracket ("[") followed by any title*
* information desired, followed by a right bracket ("]") followed by a *
* sequence of moves. The sequence of moves is assumed to start at ply=1, *
* with white-to-move (normal opening position) and can contain as many moves*
* as desired (no limit on the depth of each variation.) The file *must* be *
* terminated with a line that begins with "end", since handling the EOF *
* condition makes portable code difficult. *
* *
* Book moves can either be typed in by hand, directly into book_add(), by *
* using the "book create/add" command. Using the command "book add/create *
* filename" will cause book_add() to read its opening text moves from *
* filename rather than from the keyboard *
* *
* In addition to the normal text for a move (reduced or full algebraic is *
* accepted, ie, e4, ed, exd4, e3d4, etc. are all acceptable) some special *
* characters can be appended to a move. *
* *
* ?? -> Never play this move. since the same book is used for both *
* black and white, you can enter moves in that white might play, *
* but prevent the program from choosing them on its own. *
* ? -> Avoid this move except for non-important games. These openings *
* are historically those that the program doesn't play very well, *
* but which aren't outright losing. *
* = -> Drawish move, only play this move if drawish moves are allowed *
* by the operator. This is used to encourage the program to play *
* drawish openings (Petrov's comes to mind) when the program needs*
* to draw or is facing a formidable opponent (deep thought comes *
* to mind.) *
* ! -> Always play this move, if there isn't a move with the !! flag *
* set also. This is a strong move, but not as strong as a !! *
* move. *
* !! -> Always play this move. This can be used to make the program *
* favor particular lines, or to mark a strong move for certain *
* opening traps. *
* *
* {Play nn%} is used to force this specific book move to be played a specific*
* percentage of the time, and override the frequency of play that *
* comes from the large pgn database. *
