"Mega Evil" in setting.txt

[Ratqueen]

Could someone explain to me exactly what the following lines in the settings.txt file do?

AI Uses Mega Evil Empire := True
AI Mega Evil Empire Threshold Score Thousands := 500
AI Human Mega Evil Empire Score Percent := 170
AI Computer Mega Evil Empire Score Percent := 250

I've read in MM's FAQ that they have to do with how soon all computer-controlled players break their treaties with our empire and declare war. They do so a little too quickly for my taste and I would like to modify the related setting. I'm just not sure which one it is.

What if I put "False" in the first field? Would it turn it off completely? (I'd rather just make it so they declare war a little later though.)

Thanks.
