This stuff is now kept locally in the bot code so that it doesn't infest the rest of the engine. And please don't read the new botsupp.txt file as some new means to configure bots! This was merely done to get this data out of the way. The bots are still broken beyond repair and virtually unusable, even if proper data is provided for all weapons.
