Usage: "polyglot make-book <<options>".
"make-book" options are:
- "-pgn"
Name of the input PGN file. PolyGlot should support any
standard-conforming file. Let me know if you encounter a problem.
- "-bin"
Name of the output binary file. I suggest ".bin" as the extension but
in fact PolyGlot does not care.
- "-max-ply" (default: infinite)
How many plies (half moves) to read for each game. E.g. if set to
"20", only the first 10 full moves of each game will be scanned.
- "-min-game" (default: 3)
How many times must a move be played to be kept in the book. In other
words, moves that were played too rarely will be left out. If you
scan full games "2" seems a minimum, but if you selected lines
manually "1" will make sense.
Example: "polyglot make-book -pgn games.pgn -bin book.bin -max-ply 30".
Building a book is usually very fast (a few minutes at most). Note
however that a lot of memory may be required. To reduce memory usage,
select a ply limit.
