|-f filename, --outfile filename|
|Write the bearoff database to filename. This option must be given.|
|-t PxC, --two-sided PxC|
|Generate a two-sided bearoff database for P points and C chequers for each player. Be warned that the size of the database grows rapidly with larger numbers of points and chequers.|
|-o P, --one-sided P|
|Generate a one-sided bearoff database for P points. One-sided bearoff databases are always generated for up to fifteen chequers.|
|-s N, --xhash-size N|
|Use a memory cache of size N while building the database. If the cache is smaller than the database size, database generation will be slower due to disk writes.|
|-O filename, --old-bearoff filename|
|Reuse an already generated bearoff database. Any needed data already in this database will just be copied without regenerating it.|
|Do not write the normal bearoff database header.|
|Do not calculate cubeful equities for two-sided databases.|
|Do not compress one-sided databases.|
|Do not include gammon distributions in one-sided databases.|
|Rather than storing exact probabilities, approximate probabilities in a one-sided database with a normal distribution.|
|Show version information and exit.|
|Display usage and exit.|
To generate a two-sided database for up to eight chequers on six points:
makebearoff -t 6x8 -f gnubg_ts.bd
Note that this database is 72MB in size. To generate a one-sided database for up to fifteen chequers on ten points:
makebearoff -o 10 -f gnubg_os.bd
Note that this database is 118MB in size.
