/* The reason this exists in C++, is that a user can trash his ai/ dir,
|
|
|
|
* leaving no AIs available. The complexity to solve this is insane, and
|
|
|
|
* therefor the alternative is used, and make sure there is always an AI
|
|
|
|
* available, no matter what the situation is. By defining it in C++, there
|
|
|
|
* is simply now way a user can delete it, and therefor safe to use. It has
|
|
|
|
* to be noted that this AI is complete invisible for the user, and impossible
|
|
|
|
* to select manual. It is a fail-over in case no AIs are available.
