There's also a new version of Dueller available. As well as even more
general robustness, version 1.2 adds the option to repeatedly play a
single game (at any match score) instead of playing the match to
completion. This will allow more in-depth investigation of the outcome
at particular scorelines.
There probably won't be any more major versions of Dueller released
before the gnu-playing version.
