I see what you're getting at, but personally i really like having plenty of documentation in the config files. That way when you're editing the config file, you can know exactly what you're doing and have good descriptions right in front of you....
Of course this is no substitute for other documentation like manual/wiki etc
Maybe the answer is to have two .conf files - one, the example, that contains the comments as it is now, and the other, the basic config file, with bare minimum comments.
Of course, this means twice as much work for Timo, unless he can do this with his IDE somehow (have two different 'comment' fields, one for the .example.conf, and one for the minimal version)? Since I'm not a programmer and never used an IDE or cvs, not sure how dumb this sounds... ;)
