OK, I'll release my tool: http://www.gnubg.org/media/boa.tar.gz

The tar file contains source code and executable for windows. It reads a
file gnubg_os0.bd for each instance. The database file must be in the
same directory as you run the tool.

It works as you suggested. Example: type at the prompt:
boa 1234 4101

(boa = bearoff analyser)

Player on roll has 4 men on acepoint, 1 man on 2-point, no men on
3-point, and 1 man on four point. Opponent (not on roll) has 1 man on
acepoint, 2 men on his twopoint, 3 men on 3-point, 4 men on his four point.

This is just meant as an example of how to turn the database into
something simple. I would guess it's pretty simple to make this program

Features: Source code provided. Reports gammons
Requirements: glib and gobject, gnubg_os0.bd
Known bugs: no checking whenever board contains less than 16 checkers.

Good luck!
