Short Answer:
Actually that would be the mappers. And Im afraid that there isnt one. The best at the moment is something in the desctription such as "best played with xxxxxxx mod"
Longer Answer:
There are 3 basic sets of commands for Dom3 which are all extensive enough to be a whole subject of study for anyone.
A) MODDING changing the things that the game can use
B) MAPPING changing the game for a particular map
C) COMMAND LINE (servers, default settings, automating maps, automating game creation)
You can create a command line which will tie a map and mod together. That could be a batch file, or shortcut, or executable. I havent considered it enough to be sure if thats too confusing for the average player.
