Here's Crafty's outline of creating a book: >>>>>>>> EPD Kit revision date: 1996.04.21 found computer opening book file [./bookc.bin]. 4 piece tablebase files found 1385kb of RAM used for TB indices and decompression tables hash table memory = 6M bytes. pawn hash table memory = 1M bytes. Crafty v17.8 White(1): book create usage: book|books create filename maxply [minplay] [win/lose ] White(1): <<<<<<<< So you could get by with something like: book create games.pgn 50 and that would make a book from the file "games.pgn" and it would be able to follow that book for 25 moves (50 plys). See the Crafty.doc file for a better more complete explanation. But if you have the space for the 12mb book at the Crafty ftp site, that takes a little bit of download time, but it's a good book.
