Enabling Halloween Mode

[djotaku]

I took a look at this page http://wiki.teamfortress.com/wiki/Halloween_mode and I see that at the most simple level what I need to do is

set tf_forced_holiday 2 in server.cfg

However, I wasn't sure what else I should set up in terms of map rotation and how to control whether the bad guy is Headless Horseman, Monoculus, or Merasmus. (Or to have it happen based on the map so I can have a rotation with all the Halloween baddies)

Any help with that would be appreciated.

Thanks!

While looking through my files I found that Valve has provided a txt file with Halloween maps. So that solves part of the problem, but what do I need to do to make sure the Halloween bad guys show up?
