I've updated the addtext docu:
http://graal.net/index.php/Creation/...Ctrl#Functions
The ultimative plan is to add the documentation directly to the game (Graal.exe) so that you get all needed information from calling "Graal.exe -listscriptfunctions". The next version will also print events there. That function and variable list is also copied from time to time to the servers so that /scripthelp can use the same information.
