NAME

       bearoffdump - dump a position from the GNU Backgammon bearoff database

SYNOPSIS

       bearoffdump file id

DESCRIPTION

       bearoffdump takes the path to a GNU Backgammon bearoff database and a position number and
       dumps the bearoff information for that position.  It can be called on either the one-sided
       bearoff database, normally /usr/share/gnubg/gnubg_os0.bd; or the two-sided bearoff
       database, normally /usr/share/gnubg/gnubg_ts0.bd.  The output from the former includes the
       probabilities of bearing off all checkers in varying numbers of moves.  The latter only
       gives the probability of winning and doubling cube equity.

       The id is difficult to derive if you don't know GNU Backgammon internals.  Each possible
       combinatorial position of checkers and points is assigned a position number, id divided by
       that number is the player position, and id modulo that number is the opponent position.
       The number of points and checkers is set when building the bearoff database and are shown
       by bearoffdump when run with any id.
