I don't use carbonite because the core code is ugly, uncommented, not correctly tabbed(see below), not split in modules(I mean comon, the quest database is in the core file) and it's just too plain big. I use Jame's leveling guides, they are free and fast(tourguide supported).
Tabbed example:
Code:
function dummy(t)
if (t=="something") then
print("you entered the password!")
else
print("access not granted")
end
end
