What are the .trn files in the botprofiles folder?
The .trn files are training files for the bot. Each bot profile can specify a certain .trn file for it to train the megaHAL brain if none exists so that it has something it can say without needing bots to see humans say messages. If no .trn file is specified in the botprofile then it will load it’s own if it exists. See the botprofile readme for info.
