OK, a little howto for all:
1. Place the GLTDynamicAI modul anywhere on the map.
2. Place a couple of KI groups on the map (with or without waypoints)
3. Name each group in the init-line of the group leader this way: <groupname> = group this;
4. Set the DAIGROUPS variable in the init-line of the module: DAIGROUPS = [<groupname#1>,<groupname#2>,<...>];
That is the minimum you must do.
Optional you can define other values for the "DAI" variables also in the init-line of the module.
