The main issue is "bookc.bin" or "books.bin".  They point Crafty in the right
direction.

But clearly, the best book for program A is not the best book for program B.  IE
Cray Blitz played positions with a fianchettoed bishop poorly.  Crafty
understands this significantly better.  For CB we had it avoid such openings
completely, while for Crafty I don't.  Giving CB crafty's book would hurt it.
Giving Crafty CB's book would not hurt crafty near as much for that
characteristic...

That's the real point of all this.  Everyone would like to think that programs
play all openings equally well.  It just isn't true...
