From the release:
Just posted are the notes from the solo game set up for the battle of Raab and the rules that were used for the changes of situation in that battle for the French as the "non-player", automated side.
The Solo Module is designed to slowly reveal an automated plan of battle for the non-player side. The rules determine the command decisions of enemy, non-player generals. They may also be used to automate the decisions of subordinate commanders in one to one game play; adding to uncertainty and unpredictability in "normal" games.
