I have a patch (which, since a few days, seems to work; I will send it
as soon as it is updated to last SVN revision) that replaces the
rulesets with lua files. In this way it would be convenient to someday
write, at least, significant parts of the AI using LUA; this would
probably make it easier for ruleset authors to write (in LUA) the AI
adapted to their rulesets, and would lower the pressure on C writers.
