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, nor-
       mally /usr/share/gnubg/gnubg_ts0.bd.  The output	from the former	in-
       cludes the probabilities	of bearing off all checkers in varying numbers
       of moves.  The latter only gives	the probability	of winning and dou-
       bling cube equity.

       The id is difficult to derive if	you don't know GNU Backgammon inter-
       nals.  Each possible combinatorial position of checkers and points is
       assigned	a position number, id divided by that number is	the player po-
       sition, 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.
