NoAI is an API (a framework) to build your own AIs in. See: http://wiki.openttd.org/wiki/index.php/AI:Main_Page With many thanks to: - glx and Rubidium for their syncing, feedback and hard work - Yexo for his feedback, patches, and AIs which tested the system very deep - Morloth for his feedback and patches - TJIP for hosting a challenge which kept NoAI on track - All AI authors for testing our AI API, and all other people who helped in one way or another -Remove: all old AIs and their cheats/hacks
