The command is not in the GUI, as it seemed that few people would have
a use for it and it has the potential to fill your disc rather rapidly
when you turn it on (rolling out a cube decision or a pair of moves
for 1296 games will create 2592 files).

You activate this by doing:

set rollout logfile <template-name>
  where template-name is the pattern for the file names which will be
  generated. For example, to save a cube decision you might do (in
  Edit->Enter Command

set rollout lofgile C:\gnubg\rollouts\cube-131103

  Then when you are ready to do a rollout you use Edit->Enter command

set rollout log on

  Now when a rollout runs, the top move/cube decision in the rollout window
  (in other words, the no-double line)

C:\gnubg\rollouts\cube-131103-00000-a.sgf
C:\gnubg\rollouts\cube-131103-00001-a.sgf
...
C:\gnubg\rollouts\cube-131103-01296-a.sgf

The second line (in this case the double line) will be in files
C:\gnubg\rollouts\cube-131103-00000-b.sgf
C:\gnubg\rollouts\cube-131103-00001-b.sgf
...
C:\gnubg\rollouts\cube-131103-01296-b.sgf

If you were rolling out 5 moves instead of a cube decision, there
would be files with -a, -b, -c, -d, and -e for the five lines.

You roll by left clicking in the area of the board where the dice
would appear. You double by left clicking on the doubling cube. You
accept by clicking on the cube.
