tron@2549:  * This AI was created as a direct reaction to the big demand for some good AIs
tron@2549:  * in OTTD. Too bad it never left alpha-stage, and it is considered dead in its
tron@2549:  * current form.
tron@2549:  * By the time of writing this, we, the creator of this AI and a good friend of
tron@2549:  * mine, are designing a whole new AI-system that allows us to create AIs
tron@2549:  * easier and without all the fuzz we encountered while I was working on this
tron@2549:  * AI. By the time that system is finished, you can expect that this AI will
tron@2549:  * dissapear, because it is pretty obselete and bad programmed.
truelight@2381:  *
tron@2549:  * Meanwhile I wish you all much fun with this AI; if you are interested as
tron@2549:  * AI-developer in this AI, I advise you not stare too long to some code, some
tron@2549:  * things in here really are... strange ;) But in either way: enjoy :)
