Each time the game runs, it generates automated documentation. This can be found in the AUTODOCS folder in My Documents/My Games/<your game>/ folder (this is the same folder your savegames etc are in). The files are:
BATTLESCRIPT.TXT SQUADDEFS.TXT TWEAKS.TXT
Which contain docs for the scripting, the squads file required attributes, and the tweaks file, respectively. The tweaks file shows both the tag and also the default value.
