kts.StartTutorialManager – legacy function, no longer used
This function was used to implement a previous version of the Tutorial but it no longer does anything useful. Instead, the tutorial is now implemented entirely in Lua code, see the files in knights_data/server/tutorial.
This function should probably be removed entirely in a future version of Knights.
Note that knights_data/server/classic/tutorial.lua also appears to be part of the old (no longer used) tutorial system, so this could also be a candidate for removal.
kts.PopUpWindow – used for showing tutorial messages.
